CAUTIONARY NOTE TO UNITED STATES INVESTORS

National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all mineral reserve and mineral resource estimates in the material change report and technical review attached as exhibits hereto (the “Exhibits”) have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Classification System. These standards differ significantly from the requirements of the United States Securities and Exchange Commissions (the “SEC”).

Without limiting the foregoing, the Exhibits use the terms “indicated” and “inferred” resources. United States investors are advised that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Under United States standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves. Further, “inferred resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the “inferred resources” will ever be upgraded to a higher category. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist, or that they can be mined legally or economically. Under Canadian rules, estimates of “inferred resources” may not form the basis of feasibility or pre-feasibility studies except in limited cases. Disclosure of “contained ounces” is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” as in place tonnage and grade without reference to unit measures. Accordingly, information concerning descriptions of mineralization, mineral resources and mineral reserves contained in the Exhibits may not be comparable to information made public by United States companies subject to the reporting and disclosure requirements of the SEC.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain statements included herein, including those that express management’s expectations or estimates of our future performance, constitute forward-looking statements within the meaning of the United States Private Securities Litigation Reform Act of 1995. Statements about mineral reserves and resources may also be deemed to constitute forward-looking statements to the extent they involve estimates, based on certain assumptions, of mineralization that may be encountered if a deposit were to be developed and mined. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as “expects”, “anticipates”, “plans”, “projects”, “estimates”, “assumes”, “intends”, “strategy”, “goals”, “objectives”, “potential”, “target” or variations thereof or stating that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and may be “forward-looking statements.”

Forward-looking statements are subject to a variety of known and unknown risks, uncertainties and other factors that could cause the actual events or results to differ from those expressed or implied by the forward-looking statements, including, without limitation, those risk set forth in the Company’s annual report on Form 40-F for the year ended December 31, 2005, under the heading “Risk Factors.” The Company’s forward-looking statements are based on the beliefs, expectations and opinions of management on the date the statements are made, and the Company does not assume any obligation to update forward-looking statements if circumstances or management’s beliefs, expectations or opinions should change. For the reasons set forth above, investors should not place undue reliance on forward-looking statements.

The following is a summary of certain portions of the WGM Report. Unless otherwise indicated, all dollar amounts set forth herein are presented in Canadian dollars.

Property Location and Description

The Hope Bay project area is located 685 kilometres (“km”) northeast of Yellowknife, in Nunavut Territory and is situated east of Bathurst Inlet in the Slave Structural Province of the Canadian Shield. The centre of the Hope Bay Property lies approximately 160 km above the Arctic Circle at 67º30’N Latitude and 107ºW Longitude. The nearest settlements are Omingmaktok, located 65 km to the west on the east coast of Bathurst Inlet, and Cambridge Bay, 170 km to the northeast, on southern Victoria Island.

The property consists of 25 Crown mineral claims, 24 Crown mineral leases, 29 Crown mineral leases pending and seven Inuit Owned Land (“IOL”) Exploration Agreements with a combined total area of approximately 110,151 hectares (“ha”). In general, there are four types of land tenure disposition on the Hope Bay Belt namely:

(a)	IOL mineral and surface rights;
(b)	Crown mineral and surface rights;
(c)	IOL surface rights and Crown mineral rights. The Nunavut Land Claims Agreement ceded both surface and mineral rights in these areas, however, it grandfathered existing rights. These grandfathered rights will revert to Nunavut Tunngavik Inc. (“NTI”) in the event they are dropped; and
(d)	IOL surface rights and Crown mineral rights. The Nunavut Land Claims Agreement ceded only surface rights in these areas.

The 25 Crown mineral claims, covering 16,491 ha, are currently in good standing with anniversary dates between 2006 and 2008. The annual assessment work requirements are $2.00 per acre ($4.94 per ha) per year. Expenditures in excess of this amount are credited against future requirements, up to a maximum of ten years, when the claims must be legally surveyed and brought to lease. The anticipated assessment work requirement in 2006 is $4,648.50 and it is to be recorded no later than December 3rd. Neither a claim nor a lease conveys surface rights.

- 3 -

The 24 Crown mineral leases and 29 Crown leases pending cover a total area of approximately 37,684 ha. There is no assessment work requirement, and the annual lease rental fee is $1.00 per acre ($2.47 per ha) and will total approximately $93,117 in 2006. The Crown is entitled to a graduated annual royalty from 5% to 14% on net profits from production from these leases.

NTI owns/administers the subsurface rights to parts of the Hope Bay Belt, including the Doris and South Patch areas. Annual assessment work requirements for the seven IOL Exploration Agreements (covering 55,976 ha) are $30.00 per ha per year. In 2006, work requirements will total approximately $1.68 million against which $578,000 in available credits have been applied, leaving a requirement for an additional $1.1 million in work. Annual fees of $4.00 per ha are payable and will amount to $223,904 in 2006. Miramar Hope Bay Ltd. (“MHBL”) has the right to convert the IOL Exploration Agreements (also referred to as concessions) into production leases prior to commencement of production. NTI is entitled to an annual royalty of 12% of pre-tax profits from production, this amount being effectively set by a limit in allowable deductions.

All claims, leases and leases pending are 100% owned by MHBL. The IOL Exploration Agreements are in the name of MHBL.

Accessibility

There is no road access to the property. Personnel, supplies and equipment are flown into the site, generally from Yellowknife using float, wheel or ski-equipped aircraft. The project area is also accessible by barge or by ship at Hope Bay or Roberts Bay, both on tidewater on the Arctic Ocean, from mid-July to the end of September. In the winter and spring, airstrips on the lake ice are able to accommodate planes as large as a C-130 (Hercules) to bring in equipment and supplies. There is an 800 metre (“m”) long packed gravel airstrip at the Boston deposit site. This can be used when activity is underway at Boston but it is too far away from Madrid and Doris (+50 km) to be of much use for those areas. During the snow-cover months, on-property movement is accomplished with snowmobiles, tracked 4WD pick-ups, other tracked vehicles and heavy equipment. In the summer months, on-property movement, including drill moves, is almost all by helicopter. The use of ATVs is restricted to a small area around the camps.

Climate

The climate is classified as Arctic, semi-arid. Snow cover can extend from early October to mid-June with some drifts persisting through July on the lee side of the larger ridges. The short summer can be plagued by unreliable weather and ground exploration can be curtailed as early as the last week of August. Winter whiteouts can last over a day and result in work stoppages. Due to its position above the Arctic Circle, the property experiences 24-hour sunlight in mid-summer and 24-hour darkness at the height of winter.

Temperatures range from -40°C to 20°C. Average annual rainfall is approximately 80 millimetres (“mm”) and snowfall 100 mm. The property is a permafrost area, with permafrost known to extend to at least 500 m vertical at Boston. Winters are harsh and often lead to poor flying conditions. The practical field season is from June through September, although major drilling campaigns, such as the ongoing 2006 program, begin as early as March. The severe weather is not expected to have a major negative impact on northern mining operations in general, although certain safety and equipment maintenance precautions are required.

Local Resources and Infrastructure

There is a more than adequate supply of water available for exploration and mining purposes, however, there is no timber on the property. There is ample and suitable room available for the establishment of mining and processing operations, waste piles and a tailings management area.

The project has two camps, the Windy Lake camp for the Doris and Madrid deposits and the Boston camp for the Boston deposit. The Windy Lake camp is a Weatherhaven tent camp with a semi-permanent central complex housing kitchen, first aid and office facilities. The camp has capacity to house approximately 80 people. The Boston camp, located on the southeastern shore of Spyder Lake is a modular “ATCO” trailer style camp, which can house approximately 50 people.

The nearest settlements are Omingmaktok (population 10), located 65 km to the west on the east coast of Bathurst Inlet, and Cambridge Bay (population 2,000), 170 km to the northeast, on the southeastern corner of Victoria Island. There is a small, variably-skilled labour pool in Cambridge Bay. Extensive training would be required for any mining operation and the bulk of the workforce would have to come from the south. There is seasonal charter float-plane and helicopter service in Cambridge Bay and there are daily commercial scheduled flights to Yellowknife and other villages in the Arctic.

Physiography

The project lies within an area of moderate relief extending south from Hope Bay and Roberts Bay, which are part of Bathurst Inlet, on the south shore of the Arctic Ocean. Maximum elevation is about 300 m above mean sea level on drumlin-like hills. The predominant drainage in the area is north into Hope Bay. Areas of felsenmeer are common and swampy areas are also present. Tundra and moss cover the ground even at higher elevations. Vegetation consists primarily of lichen, moss, dwarf willows and birches. Outcrop exposure varies from 35% to 80%. Outcrops tend to form relatively continuous, north-northwest trending ridges throughout the area with broad tundra-covered flat valleys. The many lakes are also elongate in a north-northwest direction. The area is covered by relatively thick overburden ranging up to 20 m in thickness. It consists of locally and regionally derived tills and boulder tills with lacustrine and marine sediments and clay up to 15 m thick present in larger valleys.

History

The Hope Bay Volcanic Belt (the “HBVB”) was first outlined in 1962 by J.A. Fraser of the Geological Survey of Canada during a reconnaissance-scale mapping program, known as “Operation Bathurst.” Since that time, prior to the involvement of Miramar, a number of exploration and mining companies have explored the area for gold, silver and base metal deposits.

In 1991, BHP Mineral Canada Ltd. (“BHP”) commenced a systematic exploration program along the entire Hope Bay Greenstone Belt. Mapping, prospecting, till sampling, and airborne and ground geophysical surveys were conducted. Almost 200,000 m of drilling were carried out. The BHP work led to the discovery of the Boston deposit in 1992, the Doris deposit in 1995 and the Madrid deposit in 1994. In 1996 and 1997, BHP conducted an underground bulk sampling program at Boston. From 1991 to 1998, BHP spent some $85 million on exploration of the entire belt.

In June 1999, Cambiex Exploration Inc. (“Cambiex”) of Montréal optioned the Hope Bay Project from BHP Diamonds, which had acquired all the mineral assets of BHP through an internal corporate reorganization. In December 1999, Miramar acquired a 50% interest in the Hope Bay Project from

- 5 -

Cambiex and they formed the Hope Bay Joint Venture. Cambiex later changed its name to Hope Bay Gold Corp Inc. (“HBGC”).

In 2002, Miramar and HBGC completed a business combination pursuant to which HBGC became a wholly owned subsidiary of Miramar consolidating 100% ownership of the Hope Bay Project in Miramar.

Geological Setting

The HBVB is located in the northeast portion of the Slave Structural Province (“SSP”), which is predominantly an Archean granite-greenstone-metasedimentary terrain that lies between Great Slave Lake and Coronation Gulf.

The Hope Bay Project covers most of the land underlain by the Hope Bay Greenstone Belt. The greenstone belt extends over 80 km north-south direction and is between 7 and 20 km wide, and is part of the Bathurst Block, which covers approximately 16,000 km² in the northeast portion of the SSP. The Bathurst Block is the portion of the SSP northeast of Bathurst Inlet. It is isolated from the rest of the Slave by Proterozoic cover of the Kilohigok Basin. The HBVB is within the northern portion of the Bathurst Block and is dominated by mafic volcanics with felsic volcanic and volcaniclastic products and subordinate ultramafic bodies and metasedimentary rocks.

Mineralization

     Boston Deposit

Gold mineralization at the Boston deposit is present in sub-vertical horizons of extensive hydrothermal alteration within a large iron-rich carbonate altered shear zone. Organic carbon/graphite is a common component of the Boston mineralized system. Gold occurs within and around structurally controlled quartz-carbonate veins, which have developed along lithologic contacts. Gold is associated with sulphide mineralization, mainly as clots of pyrite within the veins, as well as in the wall rocks.

Three major zones of gold mineralization have been identified. These are the B2, B3 and B4 zones. Each zone extends to over 1 km in length and is composed of numerous narrow quartz-carbonate veins with disseminated pyrite. The veins are 5 centimetres (“cm”) to 3 m in width and of variable lengths, within a 10 m to 40 m wide mineralized zone. The B2 zone is the most extensive mineralized unit of the Boston deposit. It has been drill tested down to approximately 1,000 m vertical and contains approximately 75% of the total mineral resources at the Boston deposit. It is characterized by a series of parallel, en-echelon quartz-carbonate veins along the contact between basaltic and sedimentary rocks. Gold mineralization within the B3 zone is present in an altered zone parallel to the B2 zone, but is more erratic in size and shape than the B2 zone. The B3 zone comprises a stockwork of quartz-carbonate veins within basaltic rocks near the contact with ultramafic rocks. Gold mineralization within the B4 zone is present at or near the contact between basaltic rocks to the west and sedimentary rocks to the east, some 100 m east of the B3 zone. To date, only a limited amount of diamond drilling has tested this zone and the mode of mineralization is not yet well understood.

     Doris Deposit

The overall Doris (Lakeshore Vein) system comprises several sub-parallel veins traced for more than 5,000 m along strike and extending to depths of up to 400 m below the surface. Although mineralized throughout its extent, presently only two areas of concentrated gold mineralization have been defined and they are referred to as Doris North and Doris Central. The Doris North resource area includes, from north to south, the Hinge zone and the Connector zone. The Doris Central resource is located approximately 1 km south of the Doris Hinge zone and is comprised of the Doris Central and Stringer zones. Additional mineralized veins are located west of and east of the main Lakeshore Vein system; these are known as West Valley Wall Veins and the Island Veins. The host rocks are basalts and lesser gabbros, which are variably carbonate (dolomite) altered and deformed. Little work has been completed on these narrower, more discontinuous structures.

Throughout the Doris deposits and surrounding veins, visible gold is present with the highest gold grades within stylolitic, bull quartz veins. Coarse flecks of gold, locally with pyrite and occasionally with tourmaline, occur within discrete green-yellow, micaceous stylolites. Free gold grains also occur within bull quartz, preferentially near vein contacts and along discrete fractures. Sulphide content in the veins is typically low and averages less than 2% pyrite. Rare chalcopyrite is present locally. Grey and chocolate-coloured sphalerite occurs locally with high-grade gold mineralization. Within the carbonate/paragonite altered shear zones, unmineralized fibrous quartz-dolomite with or without tourmaline knots occur up to 10 cm across. Their irregular morphology suggests significant late stretching.

The Doris North zone extends from section 14025N to 15800N, a distance of some 1,775 m including the area about 450 m north of the northern end of Doris Lake called the Hinge zone. The mineralization in the southern 550 m is referred to as the Connector zone. The Hinge zone includes that portion of Doris

- 8 -

North where the Central Vein and the Lakeshore Vein are joined at the crest of the isoclinal fold. The 2000 drilling was done to confirm the presence of the Hinge zone, and the 2002 infill drilling focused on the delineation of the zone along sections spaced 12.5 m apart with drill intercepts every 10 m vertically. Results of the 2002 drilling demonstrated that the morphology of the folded quartz vein is more complex than the earlier interpretation. Based on these results, the Hinge zone is interpreted to comprise three geologic domains. The southern two domains are separated from the northern domain by a left-lateral northwest trending brittle fault, named the Glacier Fault, with about 5 m of displacement. Another northwest trending fault, the Valley Fault, cuts the Hinge zone at its northern end. The northern fault block is significantly thinner than the southern block. Gold grades increase toward the northern extremity of the zone. Generally the best gold grades occur within the Central Vein limb, and on the Central Vein side of the Hinge crest. The table below presents several representative mineralized intersections from the Doris North zone. Hinge zone true width is approximately 70-75% of core length for the limbs and approximately 95% for the immediate hinge area itself.

Multiple phases of quartz ± carbonate veining associated with various episodes of alteration and strain occur at Doris, although only one appears to be associated with gold mineralization. At the Connector zone, the best mineralization occurs within the C2 structure. The C2 occurs at the same stratigraphic position as the Central Vein of the Hinge zone to the north, but they are separate and distinct structures. This stratigraphic position occurs at the western contact of the core and iron-rich basalt. Near 15075N there is an overlap between the Central Vein and C2 Vein. The C2 Vein ranges from 1 to 10 m in width, averaging about 4 m. From north to south at the Connector zone, the C2 structure widens from a narrow discrete structure into a shear zone often exceeding 20 m in width at shallower levels. It is typified by 10 to 80% quartz veining, of varying age and composition. The C2 structure grades southward into the Stringer zone at Doris Central, which displays an identical style of mineralization. Gold is evenly distributed throughout C2, generally as free-milling grains. It is associated with 2-3% coarse-grained pyrite and traces of sphalerite and chalcopyrite in the highest grade zones. The size and grade of the C2 structure decreases significantly below the –120 m level in the Connector zone area, although some high-grades have been intercepted to the north of 14550N within the C2 Vein.

The Lakeshore Vein varies significantly in thickness at the Connector zone, ranging from 1 to over 23 m. This variation occurs irregularly along both strike and dip. The vein itself is typified by bull quartz with irregular tourmaline septa, and commonly encapsulates strongly carbonate and sericite altered wall-rock fragments. Dolomite/sericite alteration occurs as three to four meter wide selvages to the vein. Gold mineralization is associated with 1-5% pyrite, with the highest grades occurring as free-milling grains in quartz, often associated with narrow, light yellow-green sericite partings. Highest grades occur along the hanging wall contact.

- 9 -

The Doris Central zone lies approximately 1.2 km south of Doris North. Two styles of mineralization have been identified, the Lakeshore Vein and the Stringer zone. The Stringer zone lies up to 15 m west of but locally merges with the Lakeshore Vein. The Stringer zone typically is a zone of veining in dolomite/sericite-altered basalts. Vein percentage in the Stringer zone varies from 20 to 75%, although locally the zone can appear as a massive quartz vein. Vein size varies from centimetre to metre-scale veins. The Lakeshore Vein is typically a massive quartz vein, but occasionally can appear as a zone of veining typical of the Stringer zone. In both zones, the presence of fine- to medium-grained subhedral to anhedral pyrite with the black stylolites is a good indicator of gold. The highest gold grades occur within stylolitic, bull quartz veins. Free gold grains also occur within cherty grey quartz, preferentially near vein contacts and along discrete fractures. Sulphide content in the veins is typically low and averages less than 2% pyrite. Rare chalcopyrite is locally zoned adjacent to strong gold mineralization. Grey- and chocolate-coloured sphalerite occurs locally with high-grade gold mineralization. Geological continuity is good, with variable, often high-grade gold intersections.

The table below presents several representative mineralized intersections from the Doris Central zone. True lengths are generally 70% of core length.

     Madrid Deposit Area

Gold mineralization at the Madrid area is hosted by sericitic and iron-carbonate altered iron and titanium rich basaltic rocks, and less commonly by gabbro, ultramafic rocks and interlayered argillaceous sedimentary rocks. Alteration minerals are albite, dolomite and quartz. Unlike the Doris deposit, gold mineralization at the Madrid area is characterized by multistage brecciation and alteration with at least two separate gold mineralization events. Gold occurs within north-northeast, east, southeast and north-northwest trending brecciated and carbonate altered zones, and is associated with disseminated pyrite, which replaces brecciated mafic fragments. The deposit area comprises the Naartok West, Naartok East, Rand, Spur and Suluk zones.

The Madrid system consists of numerous bifurcating and/or intersecting zones of hydrothermal alteration and mineralization that develop in predictable lithological settings and within proximity to the main structure, referred to as the Deformation Zone (“DEFZ”). Mineralization is associated with pervasive alteration, which remains poorly understood. However, although the hydrothermal alteration assemblages are slightly variable with different mineralization horizons (i.e., Naartok West, Naartok East, Suluk) and host rocks, they are essentially represented by dolomite/ankerite, sericite/paragonite, silica, albite,

- 10 -

hematite, and pyrite. An ongoing study to characterize the alteration in these areas began in 2005 to better understand the alteration processes and fluids associated with gold mineralization.

The Naartok West zone consists of two main mineralized lenses, each with a lateral east-west strike length of approximately 350 m, referred to as the Y and Z lenses. The Z lens comprises the lower structural/stratigraphic lens which sits in the immediate hanging wall of the DEFZ. The Y lens lies within the hanging wall of the Z lens. In general, the Y lens is less continuous and is associated with a weaker tenor of mineralization.

The Naartok East zone consists of two lenses, each with a north-northeast strike and a moderate northwest dip, referred to as the A1 and Ye lenses. Both lenses are very similar with only a few visually notable differences. The overall gold tenor for the A1 lens is lower than for the other zones at Naartok. The Ye lens is the most recently discovered mineralized zone of the Naartok system. The Ye lens is approximately 75 to 100 m vertically lower than the A1 lens, which is possibly related to a fault offset. Gold grades are significantly higher than in the A1 lens. However, on the whole, the alteration assemblages and primary host rocks are very similar between two lenses.

The Rand zone is roughly west striking and north dipping and occurs east of the Naartok East zone. Rand mineralization is hosted within A-type (Fe-Ti) volcanics, gabbros and graphitic argillite rocks, which are weakly to strongly brecciated. The Rand Spur mineralized area is situated north of the Suluk and Rand zones and east of the Naartok East zone. Stratigraphically, it sits in a similar position as the Suluk T2 zones, however, is more weakly mineralized. This area has received only limited drill testing.

The Suluk zone is located southeast of Rand and is situated adjacent to and east of the DEFZ near the western shore of Patch Lake. Based on 2001 drilling results, the Suluk zone was interpreted to consist of two parallel mineralized lenses. Recent compilation, however, suggests a facies change in the host basalts and that the two lenses represent one mineralized zone, with the main zone joining with the upper (and thicker) zone.

By the start of the 2003 program, four lenses had been defined in the Suluk area based on linking grade; following recognition of geological controls and stratigraphic re-interpretation along with the results of the 2003 program the lenses were further refined. The lenses were defined by the rock packages that controlled them. The T1 Horizon consists of mineralization immediately adjacent to or within the deformation zone, the west lens consists of pyrite mineralization associated with dolomite/silica/sericite alteration with local wormy sub-centimetre locally hematite-bearing veins. Visible gold sometimes occurs within these veins. The major mineralized lens is the central lens. This is a brecciated and silica/sericite/dolomite-flooded mafic volcanic and mixed volcaniclastic zone, with the host rocks replaced by locally up to 40% very fine-grained pyrite. This Fe-Ti tholeiitic flow is bounded by black argillite interflow/intraflow sediments to the west and a visually distinct spilitized flow (P.G.P.) to the east. The easternmost lens is the T3 lens, which is very similar in character to the T2 lenses but is more poorly developed and less explored. The T3 zone is characterized by numerous flow sequences of variolitic basalt, pillowed basalt, massive basalt and ultramafic rocks sporadically intercalated with moderately to strongly altered volcaniclastic packages with argillaceous material. Minor graphitic argillite lenses are also common within the T3 package of Patch Group volcanic rocks. The zone itself is proximal to the eastern P.G.P. contact, similar to the central lens along the western P.G.P. contact, and has mineralized under brittle deformation conditions. The T3 lens is variable in thickness, has moderate to strong sericite/dolomite alteration with weak silica and weak to moderate pyrite mineralization (usually 1-5%). Visible gold is rare.

The Suluk mineral resource reported by Miramar at the end of 2002 and reviewed by RPA, was a polygonal based estimation focusing on higher grade mineralization and utilized a 7 g Au/t cutoff grade. The total Inferred Mineral Resource reported was 1,475,000 tonnes grading 12 to 13 g Au/t containing 580,000 ounces. The Suluk resource represented 13% of the total Hope Bay mineral resources as of December 31, 2002.

Following the 2003 drilling, a block model was created and reviewed by RPA in January 2004 prior to Miramar’s press release of January 2004 in which it disclosed mineral resources. The Suluk mineral resource was estimated for a range of cutoff grades from 1.0 to 10.0 g Au/t. Miramar used the 5 g Au/t cutoff figure for reporting purposes and reported an Indicated Mineral Resource of 527,000 tonnes grading 8.2 g Au/t containing 138,000 ounces of gold and an additional Inferred Mineral Resource of 3,615,000 tonnes grading 6.3 g Au/t containing 751,000 ounces of gold. At that time, the Suluk zones were recognized as being part of a continuous system of mineralization and as such were reported as part of the greater Madrid area mineral resource. The Suluk portion represented 16% of the total Hope Bay mineral resources as of December 31, 2003.

There was no significant drilling at Suluk in 2004 and 2005 and no new or revised mineral resource estimations have been made since the initial reporting in January 2004 and review at that time by RPA. The mineral resources disclosed in Miramar’s press release in February 2005 reported Suluk resources using a lower cutoff of 2 g Au/t to correspond with that used for reporting the overall Madrid area mineral resources. The Suluk mineral resource increased to an Indicated Mineral Resource of 1,125,300 tonnes grading 4.2 g Au/t containing 152,500 ounces of gold and an additional Inferred Mineral Resource of 14,559,600 tonnes grading 4.0 g Au/t containing 1,889,600 ounces of gold. The Suluk deposit represents 23% of the total Hope Bay mineral resource as of December 31, 2005.

Patch 14 is an additional area of defined mineralization in the Madrid trend and is located adjacent to the DEFZ approximately 4 km south of the Suluk zone. Mineralization is hosted within a zone of moderately to strongly carbonate-sericite altered, mafic volcanics and narrow intermediate porphyry dykes (Wolverine porphyry dykes). This moderately to strongly strained zone is wedged between two wider (+20 m) thick dykes of porphyry. Mineralization occurs as visible gold and disseminated pyrite, hosted within massive bull quartz and quartz-carbonate veins. At least three sub-parallel veins have been identified and exhibit a north-south strike and steep (80º) dip to the west.

The most significant structure of Patch 14, the West vein, has been traced discontinuously along strike for 400 m, however, the mineralized portion has only about a 100 m strike extent. The East vein extends for about 80 m along strike, but has much less vertical extent. Mineralization is open down a steep southerly plunge (about 70º), and along strike at depth. Drilling to the 300 m level below the bottom of Patch Lake has intersected multiple veins and gold mineralization. The main quartz lenses and corresponding grade-thickness contours at Patch 14 appear to define steep southerly plunging bodies. Although the strike extent of the mineralized zones appears to be limited, the down dip and plunge extensions of the quartz veining appear to be open.

Exploration

     2000

The Miramar/HBGC joint venture (“HBJV”) commenced a major exploration program on the Boston and Doris deposits in 2000 and for the entire project area, some 45,580.1 m of diamond drilling in 319 holes were completed.

- 12 -

The Boston ramp/decline was dewatered and 16,024.3 m were drilled in 145 holes of detailed in-fill underground drilling on a nominal 10 m by 15 m spacing. This work further defined a high-grade trend in the central portion of the B2 zone. A small number of these holes tested various possible vein orientations in the B3 zone. Twenty surface holes totaling 3,927.6 m were drilled at Boston.

Drilling at Doris concentrated on the Hinge zone on what became Doris North and Doris Central and on Doris Connector. Diamond drilling totaled 23,460.1 m in 142 holes.

Drilling in the Madrid area totaled 2,168.1 m in 12 holes.

     2001

During 2001, the HBJV completed 35,044.4 m of diamond drilling in 356 holes and 5,008.6 m of reverse circulation (“RC”) drilling in 154 holes.

The HBJV discovered two new zones in the Madrid area, the Suluk and Naartok, and completed infill drilling on the Boston deposit and the Doris Connector resource. A small amount of diamond drilling was carried out elsewhere on Madrid. The RC drilling concentrated on Madrid outside of the resource areas and on regional targets over the entire project area.

In addition, the HBJV carried out till surveys and detailed mapping and various lithogeochemical and other research projects.

     2002

During 2002, Miramar acquired 100% ownership of the project in a stock transaction with HBGC and completed 24,594.2 m of diamond drilling in 286 holes and 4,911.4 m of RC drilling in 38 holes. In addition, nineteen condemnation and geotechnical diamond drillholes totaling 752.0 m were drilled on Doris Connector.

Diamond drilling concentrated on Doris Hinge, Madrid outside of resource areas and regional targets. RC drilling concentrated on Madrid outside of resource areas and regional targets.

A Miramar contractor carried out seismic refraction surveys on the Twin Peaks (Maximus option), North Windy, Gas Cache and Nexus areas. In the case of Nexus, a bedrock seismic velocity model was generated in order to assist in interpreting alteration and structural corridors.

Heavy mineral separates till sampling was undertaken in the Doris, North Madrid and Daiwa areas. Samples in the North Madrid area indicated potential for additional resources based on gold grain morphology and assumed travel distance of the grains. In the Daiwa area, a number of unexplained anomalous till samples was returned.

Lithogeochemical studies of the existing whole rock database and new samples collected from the drilling and mapping programs were used to design a Hope Bay rock classification scheme, which was subsequently used to screen unknown samples.

Baseline environmental surveys were carried out as part of permitting activities.

- 13 -

     2003

In 2003, Miramar completed 43,238.3 m of diamond drilling in 169 holes and 1,808.8 m of RC drilling in 82 holes. In addition, eight condemnation and geotechnical diamond drillholes totaling 252.3 m were drilled on Doris Hinge, seven geotechnical diamond drillholes totaling 264.3 m were drilled on Doris Connector and seven geotechnical diamond drillholes totaling 181.5 m were drilled on Doris Central.

Deep drilling targeting the Boston deposit extended mineralization to approximately 1,000 m below surface and 600 m on strike and a surface re-mapping program was completed and generated a revised working model for the deposit. The highlight was an intersection of 54.5 g Au/t over 9.0 m true width in hole S03-293 at over 1,000 m vertical on the B2 zone.

Elsewhere diamond drilling was concentrated on the Madrid Suluk resource area, doubling the depth extent and confirming a revised geological interpretation. Elsewhere on Madrid, diamond drilling tested mineralized zones in structures and splays parallel to or adjacent to the Deformation Zone in the Patch/Rand areas. Two holes were drilled on Doris Connector and several regional targets were drilled.

RC drilling concentrated on Madrid outside the resource areas and on regional showings/target areas, including South Nexus, Gas Cache and Boston NE, all of which demonstrated potential to host significant gold mineralization.

Twelve regional targets, including those RC drilled, were the subject of regional mapping and geophysical programs. Miramar carried out detailed geophysical surveys, ground magnetics by a contractor and an E-Scan conductivity survey by another contractor over certain areas and conducted various lithogeochemical and other research projects.

A draft environmental impact statement (“EIS”) for the Doris North deposit was submitted to the Nunavut Impact Review Board (“NIRB”) in early 2003. Permitting activities continued throughout the year.

     2004

During 2004, Miramar completed 43,447.5 m of diamond drilling in 86 holes and 1,577.4 m of RC drilling in 86 holes. In addition, six geotechnical diamond drillholes totaling 290.9 m were drilled on Doris Hinge.

Diamond drilling was concentrated on Madrid Naartok where the resource area was expanded. Further drilling was carried out at Boston and a small number of holes was drilled at Doris Hinge and Madrid Suluk and Rand.

The RC drilling was concentrated on Madrid outside the resource areas and on regional targets.

Miramar also carried out detailed mapping and various lithogeochemical and other research projects.

Permitting studies and activities continued and the formal Doris North EIS was submitted to NIRB late in the year. It was returned with a request for additional studies and information.

     2005

During 2005, Miramar completed 33,197.70 m of diamond drilling in 133 holes. In addition, six geotechnical diamond drillholes totaling 66.3 m were drilled on Doris Connector. There was no RC drilling.

- 14 -

Drilling was concentrated on the Madrid Naartok zone and added to the resource base. A small number of holes were drilled elsewhere on the Madrid Trend and on regional targets, which included the North and South Nexus areas on the southern portion of the Madrid Trend, at West Kink and the Eastern Contact and Twin Peaks areas on portions of the property optioned to Maximus. In addition, infill drilling was carried out to upgrade resources in the Doris Central zone.

18 km of Induced Polarization surveying were carried out over portions of the Madrid area and the Kink and Nexus areas. In addition, Miramar carried out mapping, prospecting and various lithogeochemical, thin section and other research projects.

The Doris North Project EIS was re-submitted to the NIRB.

     2006

On March 6, 2006 the NIRB recommended to the Minister of Indian and Northern Affairs Canada that the Doris North Project proceed. Once this recommendation is accepted by the Minister, the NIRB can issue a project certificate.

The 2006 program began March 1 with camp opening and supply haulage and diamond drilling commenced March 11. To April 30, 2006, 40 holes totalling 11,934.2 were completed. Twelve holes were completed on Doris Connector and Doris Central, with the remainder on Madrid.

Drilling

WGM has not reviewed the drilling practices and details of the large amount of historic drilling carried out by BHP and the small amount carried out by Noranda Exploration Company, Limited. Based on its knowledge of these companies, it is WGM’s opinion that this historic drilling would have been carried out by reliable contractors employing industry standards common at the time.

With the exception of the 2000 underground drilling at Boston, which was carried out by Advanced Diamond Drilling of Surrey, B.C., all the Miramar drilling programs have been carried out by Major Drilling Group International Inc. (“Major”), headquartered in Moncton, N.B. The Hope Bay program is directly supervised and supported by Major’s Yellowknife office.

Drilling is carried out 24 hours a day, seven days a week from as early as March until as late as September and crews are rotated in and out of camp on a regular basis. Major has an on-site shop and supply centre and Miramar provides the camp and logistical services. At the time of writing this report, there were six diamond drills operating. There is a variety of drill types but all core is NQ2 sized (~50.7 mm in diameter).

An RC drilling rig purchased by Miramar arrived on site in late April, however, it is unlikely to see any use during the 2006 program. Reverse circulation drilling completed between 1998 and 2004 was carried out by Major and JT Thomas Drilling of Smithers, B.C. (subsequently purchased by Major in 2001). The RC drill rigs were capable of drilling only vertical holes with the exception of the 2001 program when rigs had the capability of completing angled holes.

Sampling Method and Approach

WGM has not reviewed the practices employed by historic operators, mainly BHP. Based on its knowledge of BHP and the general quality of its work, it is WGM’s opinion that BHP’s practices would have met or exceeded industry standards at the time. The remainder of this section describes Miramar practices.

The logging geologist chooses the areas to be sampled and marks the beginning and end of each sample on the core box and the core, and draws a line along the sample length indicating how the sample is to be split. He or she places two parts of a three-part numbered paper sample tag, on which basic information, including assaying/analytical instructions are marked, in the box at the end of the sample. For security reasons, neither hole number nor meterage is marked on these tags. The third portion of the tag, which does record hole number and meterage, stays in the sample tag book. The sample number is also written on the core. Samples are a minimum of 0.3 m in length, a maximum of 1.5 m and must not straddle lithological contacts, vein contacts or alteration fronts. One metre shoulder samples are taken on both the footwall and hanging wall of the mineralized areas.

The logging geologist is responsible for choosing the appropriate commercial standard for insertion into the sample stream. There must be one standard inserted in each batch of 20 samples. He or she also prepares the numbered sample tag in the manner described above, places a portion of the tag along with the standard in a plastic sample bag, writes the sample number on the bag and passes this bag on to the sample splitters/geotechnicians who ensure that the standard sample gets into the sample stream in the proper sequence. One blank sample (using locally derived sawed diabase core to disguise it as much as possible) is also included in each batch of 20 samples. The blank is often inserted immediately after highly mineralized samples to test for contamination during sample preparation at the laboratory.

Following logging, the core is photographed then passed on to the samplers. One of the two numbered tags is placed in a plastic sample bag and the same sample number is written on the bag. The sample is then diamond sawed as per the core markings, one half going into the bag and the other returned to the box and retained for future reference and further testwork as required. Once splitting of a sample is complete, the second portion of the sample tag is stapled to the core box at the end of the sample in question. The plastic bags are sealed with zap straps (plastic straps used by tradespeople to bundle wires, etc.), and put into rice bags holding a maximum of 22.6 kg to avoid excess air cargo charges. Individual rice bags contain only samples from a specific hole or portion of a hole and shipments comprise complete holes only. Shipments are flown to Yellowknife on Miramar charter aircraft.

- 18 -

Quality Assurance/Quality Control

Miramar has a comprehensive quality assurance/quality control (“QA/QC”) program in place that in WGM’s opinion meets industry standards. Miramar currently uses the services of TSL Laboratories (“TSL”) of Saskatoon, Saskatchewan to carry out check analyses as part of the QA/QC program.

Commercial standards and field blanks (one of each per batch of 20 drill core samples) are inserted into the sample stream in the field and the results of these assays are monitored and the database updated on an ongoing basis. Should any standard return a value more than two standard deviations from its expected value, that sample and all the samples in that batch are reassayed. The batch may not be re-assayed in cases where sample values in the batch are below the detection limit or if the sample population for a new standard is too small to provide a representative mean value.

The commercial laboratories used by Miramar have their own internal QA/QC protocols involving the use of standards and blanks.

Security of Samples

Miramar has protocols in place to ensure the security of its core samples and the analytical data derived from them. Among these are:

• Individual plastic sample bags are securely sealed with non-reusable zap straps prior to being placed in larger rice bags for shipment off site in charter aircraft;

• Discovery Mining Services Limited (“Discovery”), based in Yellowknife, which acts as expeditor for Miramar, unloads the sample shipments from the charter aircraft in Yellowknife. If the First Air cargo office is open, Discovery delivers the shipments into First Air’s custody and if not, Discovery holds the shipment in its secure warehouse until First Air is open;

• The shipments are flown to Edmonton using First Air/Air Canada and then are transferred to Canadian Freightways for truck transport to ALS Chemex in North Vancouver which is Miramar’s primary laboratory;

• Neither drillhole numbers nor meterages are written on the sample tags included with the samples shipped so the laboratory cannot identify the locations of the samples; and

• Assay results are restricted to a small number of Miramar personnel and only a limited number of Miramar personnel can relate the sample numbers and assays to the hole from which they came.

WGM is of the opinion that Miramar’s data and analytical security meets or exceeds industry standards. While WGM has no reason to believe any samples have or might be tampered with, a modest security improvement, at considerable expense, would involve the use of numbered zap straps to secure sample bags and thereby make any overt tampering obvious, however, someone seriously intent on contaminating samples could simply inject contaminants into bags without opening them, thereby circumventing this precaution.

Data security is maintained in large part by the fact that sample numbers do not directly identify the source of the sample. Only with extreme difficulty could a non-authorized party gain access to the data required to tie assay results to individual holes and meterages.

Data Corroboration

WGM Senior Geologist John Sullivan carried out a site visit April 22-25, 2006. During the site visit Mr. Sullivan visited the Doris deposit area, which is readily accessible via snowmobile from the Windy Lake camp and visited the Madrid deposit area where drilling was focussed at that time. Given the snow cover it was not possible to take any meaningful surface samples. The Boston deposit is some 55 km by snowmobile from the Windy Lake camp. Given safety concerns, the fact that there was no winter program at Boston and snow cover prevented making any useful observations, no visit was made there.

In addition, Mr. Sullivan reviewed a selection of current and historic drill core for the Madrid, Doris and Boston deposit areas and took three independent core samples. These were essentially core duplicates of Miramar samples. The samples were chosen to correspond with intervals sampled by Miramar to see how closely they corresponded although that was not their main purpose, which was to determine the general character and tenor of the gold mineralization. He also inspected the core logging and sawing facilities, reviewed core logging and sawing protocols, and QA/QC and security procedures. He held a considerable number of discussions with Darren Lindsay, P. Geo., the Hope Bay Project Manager, who has been involved with the project since 2001 and other Miramar technical staff on site, including the environmental officer.

Following the site visit, Mr. Sullivan visited Miramar’s North Vancouver office, where he held additional discussions with Miramar technical and management staff and gathered information and data required to prepare and complete the report. John Reddick, a WGM Senior Associate Geologist, specializing in Mineral Resource estimation, visited the North Vancouver office from April 24-28, 2006 and held discussions with Miramar technical personnel and the Miramar consultant responsible for the preparation of the Madrid Deposit Mineral Resource estimate. Mr. Michel Dagbert, B.Sc., P.Eng., of Geostat Systems International Inc., another mineral resource estimate specialist, had numerous communications with the Miramar consultant responsible for the preparation of the Madrid deposit mineral resource estimate, carried out the audit and co-authored the WGM Report.

The independent core samples were kept in WGM’s care during and after the site visit and transported to Vancouver as checked baggage. They were then taken to the ACME Analytical Laboratories Ltd. (“ACME”) ISO 9001:2000 accredited laboratory in Vancouver for analysis. They were each assayed for Au (fire assay with a gravimetric finish on 2 Assay Ton (58.3 g) subsamples) and subjected to 30-element Inductively Coupled Plasma-Atomic Emission Spectrometer analysis (ACME Group 1D procedure on 0.5 g sub-samples).

Correlation between the WGM and Miramar samples was good for the Naartok samples. The WGM sample from Doris ran considerably higher than that of Miramar, likely reflecting the often nuggety nature of the Doris mineralization. The Naartok samples exhibited elevated arsenic, nickel and strontium. The sample population is far too small to draw any conclusions regarding these elevated values.

Mineral Resource and Mineral Reserve Estimates

WGM’s assignment regarding Mineral Resources consisted of an audit of the December 31, 2005 estimates, as prepared in-house, for the Madrid Deposit Area resource zones, namely Naartok West, Naartok East and Rand.

Miramar has also prepared updated in-house Mineral Resource estimates for the Boston and Doris deposits and other zones in the Madrid Deposit Area. These estimates have been updated by Miramar periodically since they were last the subject of an independent NI 43-101-compliant technical report,

- 20 -

namely one prepared by RPA and dated September 2, 2003. In Miramar’s opinion, the changes since the RPA report have not been material. WGM has neither reviewed nor audited the estimates. For the sake of completeness, WGM reported them as supplied by Miramar.

In WGM’s opinion, the independent audit results and its acceptance and approval of Miramar’s Mineral Resource estimates for the Naartok West, Naartok East and Rand Zones fulfil the requirement of NI 43-101.

The following tables set forth the indicated and inferred mineral resources at the Hope Bay Project as set forth in the WGM Report as at December 31, 2005:

Cautionary Note to U.S. Investors concerning estimates of Resources. This table uses the terms “indicated resources” and “inferred resources”. The Company advises U.S. investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. See “Cautionary Note to United States Investors.”

Cautionary Note to U.S. Investors concerning estimates of Inferred Resources. This table uses the term “inferred resources.” “Inferred resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable. See “Cautionary Note to United States Investors.”

Miramar reports a Probable Mineral Reserve of 458,200 t grading 22 g Au/t for the Doris Hinge Zone which is included in the Indicated Mineral Resource. This Probable Mineral Reserve was estimated during the course of a Feasibility Study carried out by Steffen Robertson and Kirsten (Canada) Inc. (“SRK”) on the Doris North Project in 2002. A summary of the Feasibility Study supporting the Probable

- 22 -

Mineral Resource was presented in an independent technical report dated February 2003 and filed on SEDAR February 10, 2003. This Probable Mineral Reserve is included within the Indicated Mineral Resource reported in Table 10, to which dilution of 39% and a mining recovery factor of 95% have been applied. The price of gold used in the Feasibility Study was US$325/ounce.

Doris North Feasibility Study

In 2002, Miramar commissioned a Feasibility Study on the Doris North deposit. SRK managed the study and the principal base case parameters and conclusions were as follows:

Gold Price	US$325
Exchange Rate	1.575
Total Ore Milled	467,157 t *
Daily Throughput	668 t
Diluted Grade	21.9 g Au/t
Metallurgical Recovery	94.9%
Total Gold Recovered (2.1 years)	311,693 oz
Cash Cost	US$109/oz
Total Cost	US$190/oz
CAPEX	C$39.3M
Net Pre-tax Cash Flow	C$69.3M (incl. a 1.8% NSR payable to NTI)
Pre-tax ROR	136%
Payback Period	6.6 months

* Total made up of the 458,200 t Probable Mineral Reserve at Doris Hinge plus 9,000 t of mineralized underground material stockpiled at Boston.

The Feasibility Study also pointed to a robust project. The results were detailed in a technical report filed on SEDAR on February 10, 2003.

Portions of the Feasibility Study and certain of its parameters and conclusions have been revisited by Miramar since its completion, in particular with regard to the recent and general rapid increase in the cost of energy generation, plant equipment and construction materials. Miramar feels that these increases have been more than offset by the increase in the price of gold since 2003.

Environmental Matters

     General

Reportable spills are those over 25 litres, including fuel, sewage, salt and grey water. During 2005, there were two reportable fuel spills, both at the Windy Lake camp. Remediation had been undertaken and it is hoped the spills will be “closed off” before the end of 2006.

There was a 19,000 l fuel spill at the Windy Lake camp during 2004. On May 26, 2006, Miramar, MHBL and Miramar subsidiary, Miramar Con Mine Ltd. were each charged in relation to the spill. Miramar does

- 23 -

not anticipate that the charges will materially adversely affect Miramar’s financial condition or results of operations, or its ability to develop the Hope Bay Project.

There were two reportable spills at Boston in 2003. It is planned to apply for close off during 2006.

In general, remediation involves treating contaminated water and soil and leaving it on site, however, depending on circumstances it may be required to take such material off site for permanent disposal.

A contractor is carrying out certain of the monitoring and soil and water testing activities related to the outstanding incidents.

     Environmental and Land Use Licenses

Miramar holds two water licences issued by the Nunavut Territorial Government. These are for water use and waste disposal sites for the Boston and Windy Lake camps, require that certain tests be carried out on a regular basis and they must be renewed on an annual basis. Starting in 2006, there are certain measurable usage amounts prescribed with the licence fees based to some extent on actual usage. The cost for these licences is small.

There are two Nunavut Land Use Licences; one licence is for underground and exploration work in and around the Boston deposit site and another is for all other exploration work and the camps in the Hope Bay project area. These licences must also be renewed annually and the cost is nominal.

     Doris North EIS

Miramar filed a draft EIS with the NIRB in early 2003. The draft EIS provided details on the Doris North Project including the project description, environmental baseline studies, impact assessments, socio-economic considerations, environmental management plans and reclamation and closure plans, which responded to the NIRB guidelines issued in October 2002. The project was reviewed under a NIRB Part 5 review as provided under Article 12 of the Nunavut Land Claims Agreement.

In late 2004 the “final” EIS was submitted and returned by NIRB with a request for more studies and information. The EIS was submitted again in late 2005 and on March 6, 2006, the NIRB recommended to the Minister of Indian and Northern Affairs Canada that the Doris North Project proceed. If this recommendation is accepted by the Minister, the NIRB can issue a project certificate, which will govern the conditions under which development of the mining and processing operation may proceed.

2006 Work Plan and Budget

WGM has reviewed and supports Miramar’s 2006 work plan and budget.

Miramar plans to spend approximately $31 million at Hope Bay in 2006. The program will be directed toward two key objectives:

1. To complete drilling and technical studies sufficient to define a second phase of development at Hope Bay following the proposed Doris North Project, which is now advancing through the permitting process. There are two scenarios being contemplated which define the range of future production, a) A 350,000 ounce per year combined open pit and underground operation, and b) A large open pit concept, which would determine if the northern-most part of the Madrid system can support a larger scale open pit operation potentially producing 500,000 – 750,000 ounces per

- 24 -

	year. This scenario would also incorporate high-grade feed from the Doris and Boston deposits; and
2.	Initiate a new exploration model for Hope Bay that focuses on the geological similarities including regional faults, alternation and mineralization with the Timmins and Larder Lake areas in Ontario and ensure sufficient exploration is completed on the Hope Bay belt to meet or exceed any assessment work requirements.

The estimated cost breakdown for the 2006 program is presented in the table below.

1. SUMMARY

Miramar Mining Corporation (“Miramar”) retained Watts, Griffis and McOuat Limited (“WGM”) to carry out an independent technical review of the Hope Bay gold project located in the West Kitikmeot area of Nunavut, near Bathurst Inlet and Coronation Gulf on the northeastern corner of the Archean-aged Slave geological province. John R. Sullivan, P.Geo., B.Sc., is solely responsible for all sections of the report with the exception of the Summary, Section 16.2, Section 20 and Section 21. Michel Dagbert, B.Sc., P.Eng., is solely responsible for Section 16.2 of this report. Messrs. Sullivan and Dagbert share responsibility for the Summary, Section 20 and Section 21 of the report.

Miramar is North Vancouver based and listed on the Toronto Stock Exchange. It owns the Con property in Yellowknife, NWT, a large past producing high-grade gold mine. Production ceased at the Con in 2003 and reclamation activities are ongoing. The Hope Bay property is 100% owned by Miramar subsidiary Miramar Hope Bay Ltd. and hosts several zones of significant gold mineralization grouped into the Doris and Boston deposits and the Madrid Deposit Area.

Miramar requires this report as part of its public disclosure obligations and it may be used to support financing activities. As part of its assignment, WGM audited the recently completed Mineral Resource estimates prepared by Miramar for the Naartok East, Naartok West and Rand gold zones, which comprise a large portion of the Madrid Deposit Area. WGM’s audit was carried out and the report was prepared in compliance with the standards of the Canadian Securities Administrators’ National Instrument 43-101 (“NI 43-101”) and the Council of the Canadian Institute of Mining, Metallurgy and Petroleum definitions (“CIM Standards”).

Miramar has also prepared updated in-house Mineral Resource estimates for the Boston and Doris Deposits and other zones in the Madrid Deposit Area. These estimates have been updated by Miramar periodically since they were last the subject of an independent NI 43-101-compliant technical report, namely one prepared by Roscoe Postle Associates Inc. (“RPA”) and dated September 2, 2003. In Miramar’s opinion the changes since the RPA report have not been material. WGM has neither reviewed nor audited the estimates. For the sake of completeness, WGM is reporting them as supplied by Miramar.

Watts, Griffis and McOuat

The Doris Deposit, Boston deposits and Madrid Deposit Area occur in close proximity to a major structure or structural zone known to extend for at least the 80 km north-south strike length of the Miramar Hope Bay property. The deposits and setting are similar to lode gold deposits found elsewhere in the Archean and favourable comparisons can be made with the Porcupine and Holloway Camps found on the Destor-Porcupine Fault Zone and the Kirkland Lake, Larder Lake, Cadillac-Malartic and Val d’Or Camps found on the Cadillac-Larder Lake Break, all in the Abitibi Belt of Ontario and Quebec.

In recent times, gold was documented in the area in 1965. The first significant modern work was carried out by BHP Minerals Canada Ltd. between 1991 and 1998. This work culminated with an underground exploration and bulk sampling program on the Boston deposit.

Miramar acquired its initial interest in the property in 1999 and since then has carried out continual aggressive exploration programs, largely focussed on diamond drilling and has succeeded in finding several new significant gold zones and numerous showings, many of which have yet to be fully explored.

WGM has audited the December 31, 2005 Mineral Resource estimates, as prepared by Miramar for the Naartok-Rand sectors of the Madrid Deposit Area and is satisfied that the estimates have been prepared in an acceptable manner and in compliance with the requirements of NI 43-101 and the CIM Standards. WGM accepts the results as supplied by Miramar.

In WGM’s opinion, the independent audit results and our acceptance and approval of Miramar’s Mineral Resource estimates for the Naartok West, Naartok East and Rand zones fulfil the requirement of NI 43-101.

The Hope Bay Indicated and Inferred Mineral Resource estimates as of December 31, 2005 are documented below.

In addition to Indicated and Inferred Mineral Resources, Miramar reports a Probable Mineral Reserve of 458,200 t grading 22 g Au/t for the Doris Hinge Zone. This Probable Mineral Reserve was estimated during the course of a Feasibility Study carried out by Steffen Robertson and Kirsten (Canada) Inc. (“SRK”) on the Doris North Project in 2002. A

summary of the Feasibility Study supporting the Probable Mineral Resource was presented in an independent technical report dated February 2003 and filed on SEDAR February 10, 2003. This Probable Mineral Reserve is included within the Indicated Mineral Resource, to which dilution of 39% and a mining recovery factor of 95% have been applied. The price of gold used in the Feasibility Study was US$325/ounce.

In a relatively short period of time, Miramar has succeeded in outlining significant Archean lode gold Mineral Resources hosted by several deposits/groups of deposits on the Hope Bay property. The gold mineralization is hosted within or very close to a major deformation zone, the DEFZ, similar in age and nature to the prolific Destor-Porcupine Fault Zone and Cadillac-Larder Lake Break in the Abitibi Belt of Central Canada. Such major deformation zones are known to host significant deposits on a regular, if not exactly predictable, basis.

The Hope Bay property is 80 km in strike length and a large portion of it remains relatively underexplored. Upwards of 75 surface showings and isolated anomalous drill intersections in favourable geological settings are being evaluated and plans prepared for systematically testing these targets. Detailed ground magnetic surveying is being carried out on some this winter and lithogeochemical data are being evaluated as appropriate. The targets will be prioritized, initially emphasizing targets on and near the DEFZ, and selective drilling will begin later in 2006.

It is WGM’s opinion that the Hope Bay property is underexplored and retains considerable potential for the discovery of additional gold deposits. Miramar’s programs are well focussed and managed, and strongly supported by senior management. The ingredients for further success are in place.

Watts, Griffis and McOuat

Since beginning work on the Hope Bay property in 2000 until the end of 2005, Miramar spent approximately $112 million on exploration and development and drilled over 200,000 m in 1,670 holes.

WGM has reviewed and supports Miramar’s 2006 work plan and budget. We recommend that it be completed as planned.

Miramar plans to spend approximately $31 million at Hope Bay in 2006. The program will be directed toward two key objectives:

1.

To complete drilling and technical studies sufficient to define a second phase of development at Hope Bay following the proposed Doris North Project, which is now advancing through the permitting process. There are two scenarios being contemplated which define the range of future production, a) A 350,000 ounce per year combined open pit and underground operation, and b) A large open pit concept, which would determine if the northern-most part of the Madrid system can support a larger scale open pit operation potentially producing 500,000 – 750,000 ounces per year. This scenario would also incorporate high-grade feed from the Doris and Boston deposits; and

2.

Initiate a new exploration model for Hope Bay that focuses on the geological similarities including regional faults, alteration and mineralization with the Timmins and Larder Lake areas in Ontario and ensure sufficient exploration is completed on the Hope Bay belt to meet or exceed any assessment work requirements.

The work plan includes 55,300 m of diamond drilling, the direct cost of which will amount to $12,900,000. The majority of the meterage will be on the Naartok Zones and elsewhere in the Madrid Deposit Area and overall Madrid Trend. Smaller programs are planned at Doris and Boston, and on regional targets. The program is flexible and priorities will be re-evaluated on an ongoing basis depending on the success achieved on individual targets. This is a prudent approach supported by WGM.

4. PROPERTY LOCATION AND DESCRIPTION

4.1 PROPERTY LOCATION

The Hope Bay project area is located 685 km northeast of Yellowknife, in Nunavut Territory and is situated east of Bathurst Inlet in the Slave Structural Province of the Canadian Shield. The centre of the Hope Bay Property lies approximately 160 km above the Arctic Circle at 67º30’N Latitude and 107ºW Longitude. The nearest settlements are Omingmaktok, located 65 km to the west on the east coast of Bathurst Inlet, and Cambridge Bay, 170 km to the northeast, on southern Victoria Island. The property location is shown on Figure 1.

4.2 PAST MINING ACTIVITY

Previous owner BHP Mineral Canada Ltd. (“BHP”) carried out an underground exploration/test mining/bulk sampling program via a decline on the Boston deposit in 1996/1997. Numerous rock piles comprising mineralized underground material remain near the portal, which is securely blocked from access. To the best of Miramar’s knowledge, this material is not acid generating. There is no settling pond at or near the mining area. There have been no mineral processing activities on or near the property; therefore there are no tailings impoundment areas in the vicinity.

4.3 PROPERTY DESCRIPTION

The property consists of 25 Crown mineral claims, 24 Crown mineral leases, 29 Crown mineral leases pending and seven Inuit Owned Land (“IOL”) Exploration Agreements with a combined total area of approximately 110,151 ha (Figure 2). In general, there are four types of land tenure disposition on the Hope Bay Belt (Figure 3), namely:

1.	IOL mineral and surface rights;
2.	Crown mineral and surface rights;
3.	IOL surface rights and Crown mineral rights. The Nunavut Land Claims Agreement ceded both surface and mineral rights in these areas, however, it grandfathered existing rights. These grandfathered rights will revert to Nunavut Tunngavik Inc. (“NTI”) in the event they are dropped; and

4. IOL surface rights and Crown mineral rights. The Nunavut Land Claims Agreement ceded only surface rights in these areas.

The 25 Crown mineral claims, covering 16,491 ha, are currently in good standing with anniversary dates between 2006 and 2008. The annual assessment work requirements are $2.00 per acre ($4.94 per ha) per year. Expenditures in excess of this amount are credited against future requirements, up to a maximum of ten years, when the claims must be legally surveyed and brought to lease. The anticipated assessment work requirement in 2006 is $4,648.50 and it is to be recorded no later than December 3^rd. Neither a claim nor a lease conveys surface rights.

The 24 Crown mineral leases and 29 Crown leases pending cover a total area of approximately 37,684 ha. There is no assessment work requirement, and the annual lease rental fee is $1.00 per acre ($2.47 per ha) and will total approximately $93,117 in 2006. The Crown is entitled to a graduated annual royalty from 5% to 14% on net profits from production from these leases.

NTI owns/administers the subsurface rights to parts of the Hope Bay Belt, including the Doris and South Patch areas. Annual assessment work requirements for the seven NTI Exploration Agreements (covering 55,976 ha) are $30.00 per ha per year. In 2006, work requirements will total approximately $1.68 million against which $578,000 in available credits have been applied, leaving a requirement for an additional $1.1 million in work. Annual fees of $4.00 per ha are payable and will amount to $223,904 in 2006. MHBL has the right to convert the NTI Exploration Agreements (also referred to as concessions) into Production Leases prior to commencement of production. NTI is entitled to an annual royalty of 12% of pre-tax profits from production, this amount being effectively set by a limit in allowable deductions.

All claims, leases and leases pending are 100% owned by MHBL. The NTI Exploration Agreements are in the name of MHBL. The tenure data are summarized in Table 1 below and details are provided in Appendix 1.

4.4 UNDERLYING AGREEMENTS

Neither BHP nor Cambiex/Hope Bay Gold Corp Inc., both previous owners/vendors of the property, hold any equity interest in the property nor are entitled to a royalty on production from the property.

4.5 SHERWOOD AGREEMENTS

On June 10, 2002, Sherwood Mining Corporation (“Sherwood”) signed an option agreement with Miramar to earn up to a 70% interest in any diamondiferous bodies discovered on the Hope Bay property. The terms of the agreement allowed Sherwood to earn a 50% interest by spending $2 million on diamond exploration over four years. Sherwood could have increased its interest by another 20% by solely funding a 20 tonne bulk sample project on any diamondiferous body on the property. The agreement was subsequently terminated.

On December 29, 2003, Sherwood signed a separate option agreement with Miramar to earn up to a 60% interest in the Chicago Trend, located on the southwest portion of the property, by spending $3.1 million on exploration work in phases over a period of three years. The agreement terminated March 29, 2005.

4.6 MAXIMUS AGREEMENT

On June 25, 2004, Maximus Ventures Ltd. (“Maximus”) signed a letter of intent whereby Maximus could earn a 75% interest in the Eastern Contact and Twin Peaks areas. The initial terms of the agreement allowed Maximus to earn its interest by spending $7.5 million on exploration over three years; once the Maximus option has vested, the property will be explored through a joint venture. This agreement was amended on March 20, 2006 at which

- 15 -

Watts, Griffis and McOuat

time Maximus dropped the Eastern Contact area and added the Chicago area to the agreement. The option property now comprises eight Crown claims, three Crown leases, three Crown leases pending and portions of two NTI Exploration Agreements, totalling 11,147 ha. Required expenditures remain $7.5 million, but now must be incurred by April 30, 2009. Magnetic and Horizontal Loop electromagnetic (“HLEM”) surveys, along with mapping and 3,000 m of drilling are planned for various portions of the optioned properties during 2006. Miramar is the operator.

5. ACCESSIBILITY, CLIMATE AND LOCAL RESOURCES AND
INFRASTRUCTURE AND PHYSIOGRAPHY

5.1 ACCESSIBILITY

There is no road access to the property. Personnel, supplies and equipment are flown into the site, generally from Yellowknife using float, wheel or ski-equipped aircraft. The project area is also accessible by barge or by ship at Hope Bay or Roberts Bay, both on tidewater on the Arctic Ocean, from mid-July to the end of September. In the winter and spring, airstrips on the lake ice are able to accommodate planes as large as a C-130 (Hercules) to bring in equipment and supplies. There is an 800 m long packed gravel airstrip at the Boston deposit site. This can be used when activity is underway at Boston but it is too far away from Madrid and Doris (+50 km) to be of much use for those areas. During the snow-cover months, on-property movement is accomplished with snowmobiles, tracked 4WD pick-ups, other tracked vehicles and heavy equipment. In the summer months, on-property movement, including drill moves, is almost all by helicopter. The use of ATVs is restricted to a small area around the camps.

5.2 CLIMATE

The climate is classified as Arctic, semi-arid. Snow cover can extend from early October to mid-June with some drifts persisting through July on the lee side of the larger ridges. The short summer can be plagued by unreliable weather and ground exploration can be curtailed as early as the last week of August. Winter whiteouts can last over a day and result in work stoppages. Due to its position above the Arctic Circle, the property experiences 24-hour sunlight in mid-summer and 24-hour darkness at the height of winter.

Temperatures range from -40°C to 20°C. Average annual rainfall is approximately 80 mm and snowfall 100 mm. The property is a permafrost area, with permafrost known to extend to at least 500 m vertical at Boston. Winters are harsh and often lead to poor flying conditions. The practical field season is from June through September, although major drilling campaigns, such as the ongoing 2006 program, begin as early as March. The severe weather does not have a major negative impact on northern mining operations in general, although certain safety and equipment maintenance precautions are required.

- 17 -

Watts, Griffis and McOuat

5.3 LOCAL RESOURCES AND INFRASTRUCTURE

The property has no permanent inhabitants. Some Inuit cross through and hunt in the area on occasion and there is limited archeological evidence of historic activity of this sort. There is a more than adequate supply of water available for exploration and mining purposes, however, there is no timber on the property. There is ample and suiTable room available for the establishment of mining and processing operations, waste piles and a tailings management area.

The project has two camps, the Windy Lake camp for the Doris and Madrid deposits and the Boston camp for the Boston deposit. The Windy Lake camp is a Weatherhaven tent camp with a semi-permanent central complex housing kitchen/first aid/dry/office facilities. The camp has capacity to house approximately 80 people. Certain upgrades were underway during the WGM site visit. The Boston camp, located on the southeastern shore of Spyder Lake is a modular “ATCO” trailer style camp, which can house approximately 50 people.

The nearest settlements are Omingmaktok (population 10), located 65 km to the west on the east coast of Bathurst Inlet, and Cambridge Bay (population 2,000), 170 km to the northeast, on the southeastern corner of Victoria Island. There is a small, variably-skilled labour pool in Cambridge Bay. Extensive training would be required for any mining operation and the bulk of the workforce would have to come from the south.

In Cambridge Bay there are several stores, a hotel, restaurant, limited office space and some Nunavut government services available. There is a primary and secondary school and a staffed nursing station. There is seasonal charter float-plane and helicopter service and there are daily commercial scheduled flights to Yellowknife and other villages in the Arctic.

5.4 PHYSIOGRAPHY

The project lies within an area of moderate relief extending south from Hope Bay and Roberts Bay, which are part of Bathurst Inlet, on the south shore of the Arctic Ocean. Maximum elevation is about 300 m above mean sea level on drumlin-like hills. Relief is approximately 100 m. The predominant drainage in the area is north into Hope Bay. Areas of felsenmeer are common and swampy areas are also present. Tundra and moss cover the ground even at

- 18 -

Watts, Griffis and McOuat

higher elevations. Vegetation consists primarily of lichen, moss, dwarf willows and birches. Outcrop exposure varies from 35% to 80%. Outcrops tend to form relatively continuous, north-northwest trending ridges throughout the area with broad tundra-covered flat valleys. The many lakes are also elongate in a north-northwest direction. The area is covered by relatively thick overburden ranging up to 20 m in thickness. It consists of locally and regionally derived tills and boulder tills with lacustrine and marine sediments and clay up to 15 m thick present in larger valleys.

6. HISTORY

The Hope Bay Volcanic Belt was first outlined in 1962 by J. A. Fraser of the Geological Survey of Canada during a reconnaissance-scale mapping program, known as “Operation Bathurst.” Since that time, prior to the involvement of Miramar, a number of exploration and mining companies have explored the area for gold, silver and base metal deposits, with encouraging results, as follows:

• In 1965, trench sampling by Roberts Mining Company (“Roberts”) revealed up to 0.32 oz Au/T and 2.72 oz Ag/T at Roberts Lake near the current Doris deposit;

• In 1967, trench sampling by Radiore Uranium Mines revealed up to 2 oz Au/T over 1.41 ft, at a showing presumed to be some 10 km southwest of the present Madrid deposit, i.e., within the current Wizard grid area;

• In 1973, Hope Bay Mines Ltd. (“HBML”) outlined a silver resource, based on underground exploration, and extracted some 100,000 ounces of silver, about 10 km north of the Doris Lake deposit, off of the present Hope Bay property;

• In 1976, Perry River Nickel Mines reported assay results of more than 1 oz Au/T in quartz veins. The exact location of this showing is not known;

• In 1981, Noranda Exploration Company, Limited (“Noranda”) reported assay results of 0.53% Cu, 1.8% Zn, 0.16 oz Ag/T and 0.008 oz Au/T from diamond drill testing of EM conductors over the Wombat Zone, near the Kamik claims, in the central part of the Hope Bay property. Almost a decade later, Noranda intersected 50 to 69 g Au/t over 3 m in drillhole WBT-90-3;

• In 1985, Roberts discovered the Roberts Lake Silver showing, but could not continue further exploration due to lack of funding;

• From 1987 to 1989, Abermin Corporation (“Abermin”) explored the area from a camp at Windy Lake and discovered several showings, including the Ida Bay Silver, Ida Point Gold, and the Granite/Wombat showings. Abermin also detected gold mineralization in the southern part of the Hope Bay Belt, which later became the Boston deposit;

• In 1991, BHP Mineral Canada Ltd. (“BHP”) commenced a systematic exploration program along the entire Hope Bay Greenstone Belt. Mapping, prospecting, till sampling, and airborne and ground geophysical surveys were conducted. Almost 200,000 m of

- 20 -

Watts, Griffis and McOuat

drilling were carried out. The BHP work led to the discovery of the Boston deposit in 1992, the Doris Deposit in 1995 and the Madrid Deposit in 1994. In 1996 and 1997, BHP conducted an underground bulk sampling program at Boston. This program is discussed in Sections 17, 18 and 19. From 1991 to 1998, BHP spent some $85 million on exploration of the entire belt;

• In June 1999, Cambiex Exploration Inc. (“Cambiex”) of Montréal optioned the Hope Bay Project from BHP Diamonds (“BHP”), which had acquired all the mineral assets of BHP Minerals Canada Ltd. through an internal corporate reorganization;

• In December 1999, Miramar acquired a 50% interest in the Hope Bay Project from Cambiex and they formed the Hope Bay Joint Venture (“HBJV”). Cambiex later changed its name to Hope Bay Gold Corp Inc. (“HBGC”); and

• In 2002, Miramar and HBGC completed a business combination pursuant to which HBGC became a wholly owned subsidiary of Miramar consolidating 100% ownership of the Hope Bay Project in Miramar.

Exploration work carried out by Miramar, both during and subsequent to formation of the HBJV is discussed in Section 10.

7. GEOLOGY

7.1 REGIONAL GEOLOGY

The Hope Bay Volcanic Belt (“HBVB”) is located in the northeast portion of the Slave Structural Province (Figure 4). The Slave Province is predominantly an Archean granite-greenstone-metasedimentary terrane that lies between Great Slave Lake and Coronation Gulf and is bounded to the east by the Thelon Orogen (2020 to 1910 Ma) and to the west by the Wopmay Orogen (1950-1840 Ma; Hoffman, 1988).

Twenty-six or so granite-greenstone belts are recognized in the Slave, which were subdivided into mafic volcanic-dominated (Yellowknife-type) and felsic volcanic-dominated (Hackett River-type) by Padgham (1985). Yellowknife-type belts are typically massive to pillowed tholeiitic flows interbedded with calc-alkaline felsic volcanic and volcaniclastic rocks, clastic sedimentary rocks and rarely synvolcanic conglomerate and carbonate units. Hackett River-type belts are dominated by calc-alkaline felsic and intermediate rocks intercalated with turbidites. The HBVB is classified as Yellowknife-type. U-Pb geochronology brackets volcanism in the Slave to between about 2715 and 2610 Ma (Mortensen et al., 1988 and Isachsen et al., 1991). The volcanic belts are typically isoclinally folded and contain belt-parallel shear zones. A late (circa 2.6 Ga) “Timiskaming-type” sedimentary assemblage, consisting of conglomerate and sandstone, may overlie the main greenstone belts (Fyson and Helmsteadt, 1988). Villeneuve (1997) has subdivided the intrusive rocks into 2.70 to 2.64 Ga pre-deformation tonalite and diorite, 2.62-2.59 Ga K-feldspar megacrystic granite and post-deformation 2.60-2.58 Ga two-mica granites. In general a regional pan-Slave deformation event is recognized between 2.7 and 2.6 Ga, characterized by regional compression, plutonism and late extension (<2.583 Ga).

7.2 PROPERTY GEOLOGY

7.2.1 GENERAL

The Hope Bay Project covers most of the land underlain by the Hope Bay Greenstone Belt. The greenstone belt extends over 80 km north-south direction and is between 7 and 20 km

- 22 -

Watts, Griffis and McOuat

Figure 4. Miramar Mining Corporation Hope Bay Project Nunavut, Canada Regional Geology Map

- 23 -

Watts, Griffis and McOuat

wide, and is part of the Bathurst Block, which covers approximately 16,000 km² in the northeast portion of the Slave Structural Province (“SSP”) (Figure 4). The Bathurst block is the portion of the Slave Structural Province northeast of Bathurst Inlet. It is isolated from the rest of the Slave by Proterozoic cover of the Kilohigok Basin (Campbell and Cecile, 1976). The belt (HBVB) is within the northern portion of the Bathurst Block and is dominated by mafic volcanics with felsic volcanic and volcaniclastic products and subordinate ultramafic bodies and metasedimentary rocks. Existing U-Pb geochronology of the belt indicates that felsic volcanism spanned a period of at least 53 Ma (2716-2663 Ma; Hebel, 1999).

To the east, the belt is bordered by felsic intrusions that separate the Hope Bay belt from the Elu Inlet belt. A granodiorite northeast of the Hope Bay belt gave a U-Pb zircon age of 2672 +4/-1 Ma, suggesting a syn- to late-volcanic age of emplacement (Bevier and Gebert, 1991). The southeastern contact of the Hope Bay belt is a heterogeneous gneiss terrane that yielded a U-Pb zircon age of 2649.5 +2.9/-2.5 Ma and a titanite age of 2589 Ma, which may represent a metamorphic age (Hebel, 1999). The Hope Bay belt is bordered to the west by plutonic rocks that contain foliated mafic fragments at 2608 ± 5 Ma placing a lower limit on deformation and metamorphism (Bevier and Gebert, 1991). The metamorphic grade in the interior of the belt is lower greenschist with amphibolite grade near the belt margins.

7.2.2 BOSTON AREA

The Boston deposit is one of the larger known gold resources in the Hope Bay belt. Recent deep drilling has indicated the potential to significantly expand these resources. The geology around the Boston deposit is a bimodal assemblage of mafic and felsic volcanic rocks along with sedimentary rocks all of which are complexly folded about a large-scale synformal-anticline. Figure 5 presents the property geology in the Boston area.

Structural Geology

A large scale fold dominates the geology of the Boston area. The core of the anticline is occupied by mafic volcanic rocks that host the Boston deposit and these are in turn overlain by sedimentary rocks. The structure is best defined by facing directions recognized by graded bedding, bedding-cleavage relationships in the sedimentary rocks and from pillow shelves in the mafic volcanic rocks.

and facing directions, is unusual in that it has the broad geometry of a synform with the facing directions of an anticline making it a synformal anticline or an overturned anticline. The fold is south plunging.

Lithologies

Several suites of mafic volcanic rocks are recognized in the Boston area; these include the Boston and the East and West Spyder suites. Pillow shapes are similar between the three suites and tend to be rather small, with thin selvages and aspect ratios of about 5:1. The pillows are commonly strongly amygdaloidal, filled with calcite and epidote, which are often weathered out. Due to their flattened nature, pillow geometry does not provide reliable facing indicators. However, pillow shelves are relatively common and are often filled with calcite and epidote, which provide good facing indicators. Interflow sediments are relatively common but volumetrically minor and consist mainly of argillite with lesser chert.

Variolitic and non-variolitic mafic volcanic rocks are recognized and form consistent map units. The non-variolitic unit is the most abundant, underlying much of the map area. In the Boston suite, a distinct variolitic phase is recognized which can be correlated over several kilometres. In this unit the varioles are large and mainly developed around pillow selvages, but locally form coalesced varioles that occupy the bulk of a pillow structure. Locally the varioles are highly elongate, defining a strong stretching lineation. The variolitic unit appears to wrap around the main F2 synformal antiform (discussed below) and may be the main host rock for the Boston deposit, however, in the deposit area, strong hydrothermal alteration obscures most primary textures.

This unit tends to weather recessively and is poorly exposed. Where exposed on the lakeshores the sedimentary rocks range from quartzo-feldspathic wackes to a fine-grained argillite. Most outcrops are well-graded, providing excellent facing directions.

7.2.3 DORIS AREA

The Doris deposits are typical of the “Archean lode” or “greenstone-hosted” deposit style and occur within a steeply dipping, over 3 km-long quartz vein system in folded and metamorphosed pillow basalts. At the north end, the veins are folded to create a high-grade anticlinal hinge zone lying close to surface (the Doris Hinge), which will be the first Hope Bay resource to be brought into production. The anticlinal fold axis extends south through

- 26 -

Watts, Griffis and McOuat

Doris Lake, marking the transition between east-facing strata on the east shore of Doris Lake and west-facing strata on the west shore of Doris Lake. Figure 6 presents the property geology in the Wolverine through Doris area, taking in the Madrid Deposit Area.

Structural Geology

The dominant structure in the area is a tight to isoclinal antiform structure (Figure 7). The fold axis strikes approximately north-south and is doubly plunging. The antiform plunges shallowly to the north around the Doris deposit, and shallowly to the south at the south end of Doris Lake. The antiform axial plane is slightly inclined with an east vergence. The antiform is mapped based on younging directions from gas cavities in the pillowed Mg tholeiitic basalts. The Fe tholeiites only rarely contain gas cavities and their younging direction is inferred from adjacent Mg tholeiites.

Late brittle faults are recognized in outcrop as distinct brittle breaks, which have been preferentially weathered. These typically are less then one metre across but can be traced for over one kilometre. In several cases, stratigraphic offsets up to 5 m are recognized across these structures with a consistent apparent sinistral displacement. These structures offset the mineralization and three distinct faults are mapped and inferred in drill core; the Lakeshore Fault, the Glacier Fault and the Valley Fault. Interpreted displacements for all of these faults include left-lateral and north-side down movement. A constructed geometric model indicated that a maximum displacement of 20 m in either sense (lateral/throw) was required to give the map offsets observed on the Lakeshore Fault. These faults do not cross-cut or offset the Franklin diabase.

Several distinct suites of mafic volcanic rocks are recognized in the Doris area and are broadly divisible into Mg and Fe tholeiites. The Mg and Fe tholeiite distinction is based on the existing lithogeochemical database, however, the chemically distinct units were field located and visual descriptors for each unit were developed. Additionally, the Fe tholeiites can contain elevated TiO2 values and all rock units can be broken into subunits based on the presence or absence of varioles, amygdules and magnetism (Carpenter and Quang, 2003).

7.2.4 MADRID AREA

The Madrid Deposit Area and Madrid trend corridor is a belt of prospective lithologies and favourable gold mineralization located within the northern portion of the Hope Bay Volcanic Belt. The Madrid Deposit Area is host to the Naartok, Rand, and Suluk resources while the Madrid trend hosts the Rand Spur, Marianas, Patch 7 and Patch 14 zones. The rocks within this corridor are predominantly a north-south striking package of mafic volcanics, comprising a sequence of Fe-Ti Tholeiites, Mg Tholeiites, komatiitic basalts, synvolcanic to late gabbro and ultramafic rocks.

Gold mineralization in this corridor is most commonly associated with the high Fe-Ti tholeiites and is structurally controlled by a large-scale zone of deformation referred to as the Deformation Zone (“DEFZ”). The DEFZ trends north-south from its southern extent at the Nexus area (south of Patch Lake) through to the northern portion of Patch Lake, where the DEFZ then sharply changes orientation to an east-west trend across to Windy Lake.

Structural Geology

Ductile strain is largely represented in the Madrid area by the main strain corridor of the DEFZ and its splays, as well as within local zones of moderate to high strain (outside of the DEFZ). Intensity of the ductile strain increases towards the DEFZ where mafic volcanic rocks begin to exhibit pervasive intense foliation and locally show mylonitic textures. Splays off of the DEFZ preferentially develop along volcanic-sediment horizons, possibly related to the large competency contrast between massive flows and argillite-volcaniclastic layers. It is clear in both section and plan views that the DEFZ is not a single planar structure, but a complicated anastomosing feature with several splays and local pinch-and-swell textures.

Brittle and brittle/ductile structures are being recognised as drilling density increases in the Madrid area. Apparent discontinuities in alteration, mineralization and lithological units

- 30 -

Watts, Griffis and McOuat

generally define a set of NW trending steep structures in the Naartok area and a structure partially defining the footwall contact of the Naartok East mineralised horizon.

Lithologies

Rocks of the Naartok to Suluk Zones are classified based on textural and lithogeochemical similarities. The general stratigraphy of the northern Madrid area (Naartok West to Suluk) is composed of three major volcanic packages: the Wolverine Group (C-type rocks), the Patch Group (A-type rocks), and a C-type tholeiitic andesite (P.G.P). Stratigraphy from Naartok West includes a moderately to steeply westerly dipping package of intercalated C-type and A-type basalts and interflow sediments. At Naartok East the stratigraphy comprises a moderately westerly dipping package of intercalated C-type and A-type basalts and interflow sediments (Figure 9). The Suluk stratigraphy is similar to the other areas of Madrid.

The three major volcanic groups are distinguished primarily based on whole rock (“WR”) geochemistry and Inductively Coupled Plasma (“ICP”) trace-element geochemistry. Other factors such as volcanic textures (variolites, flow breccias), the presence of interflow sediments, volcaniclastics, and magnetically susceptible units within the Patch Group have also been used to distinguish it from the Wolverine basalt and the “pale green pillows.” The Wolverine and Patch Group contacts have a NNE strike within the Naartok area, extending from the DEFZ. These contacts are interpreted through sub-surface and surface data and appear to terminate at a NW-SE trending inferred fault, only to reappear further to the east, just north of the Rand area, as an apparent right lateral offset. The apparent thickness of all units is variable and displacement has yet to be determined.

Wolverine Group (C-type)

The Wolverine volcanic suite (“WOLV”) is separated into north and south components by the DEFZ. The rocks of the Wolverine Group south of the DEFZ comprise a series of distinctive C-type pillowed flows which are in gradational contact with intercalated aphanitic to massive to amygdaloidal basalt flows that also represent normal tholeiites. They demonstrate weak to moderate strain and have a predominantly chlorite-calcite alteration assemblage.

North of the DEFZ, the Wolverine volcanic suite is composed of a series of coalesced variolitic pillowed flows and subordinate flow breccias. The suite exhibits weak to moderate

strain and is overprinted by a predominantly chlorite-calcite alteration assemblage. The suite may also be locally unstrained to strongly strained and strongly (sericite-dolomite) altered. The normal tholeiitic (C-type) geochemistry is verified through WR geochemistry.

C-type Pillows with Argillite Matrix

The C-type pillowed basalt with argillite matrix is visually identical to an A-type equivalent. C-type varieties are found within the hanging wall relative to their A-type equivalent at Naartok West.

Textural differences (i.e., harrisitic texture in A-type variety) are sometimes recognizable and when present can be applied to distinguish the two geochemically distinctive volcanic packages.

The most effective method for elucidating the boundaries of the C- and A-type volcanic packages is WR geochemical analyses across a suite of these pillow-sediment units.

Deformation Zone

The DEFZ is an east-west trending (from Naartok West to Suluk) to north-south trending (from Suluk to South Patch Lake) corridor of intense strain and alteration. The DEFZ presents as the contact between the Wolverine and Patch Groups near the western shore of Patch Lake and through the east-west oriented valley between Windy and Patch Lakes.

Four lithologies have been truncated and entrained in this high strain-alteration zone: the Wolverine volcanics, Wolverine porphyry (quartz-feldspar phyric porphyry), argillaceous sedimentary rocks and Patch Group A-type volcanics. The proportions of these components vary from hole to hole but overall the DEFZ consists primarily of basalt of the Wolverine volcanic suite.

The volcanic rocks of the DEFZ are defined as strongly foliated (schistose) with domains of dolomite (grey) and mm-width bands of sericite (straw yellow to pale green) defining the foliation. Within the DEFZ the Wolverine porphyry occurs as salmon pink to beige coloured segregations, which are also affected by and demonstrate the pervasive foliation.

- 33 -

Watts, Griffis and McOuat

Patch Group (A-type)

The Patch Group volcanic suite is composed of a series of flows which grade from aphanitic-massive basal flows, to pillowed flows exhibiting poorly formed, small, rubbly pillows, to flow top breccias, capped by argillaceous interflow sediments. Gabbroic intrusive phases are rarely present, and where present are found near the bottom of flows. Some of the flows to the east are variolitic and their occurrence is correlated with that of ultramafics and “melanocratic” basalts. Patch Group volcanics are characteristically A-type volcanics with rare horizons of B-type. At Suluk, variolitic phases are olive green, fine-grained chloritized basalt with discontinuous variolitic texture; variolites are ovoid to round and are typically less than a few centimetres in size, but are generally larger than varioles seen in the Wolverine basalts.

8. DEPOSIT TYPES

The Hope Bay Deposits are classified as Archean lode gold-type, associated with large-scale regional structures. They are similar to deposits found in the prolific Abitibi Belt of the Superior Province of Ontario and Quebec, in particular those found along the Destor-Porcupine Fault Zone and the Cadillac-Larder Lake Break, where over 150 million ounces of gold have been produced since the early 1900s.

Gold deposits in the Hope Bay Project area display regional variations in structural and stratigraphic setting and associated mineralogy, and are subdivided into four types, as follows:

• Large carbonate (±sericite) alteration zones containing auriferous quartz and quartz-carbonate veins, such as the Boston and Doris Deposits and the South Patch zone;

• Large alteration zones within iron rich basalts containing wide areas of pyritized, silicified and albitized rock such as the Naartok, Suluk and Rand zones, and other potential zones/deposits within the Madrid trend;

• Gold in quartz-carbonate veins hosted in narrow zones along and/or cross cutting the contact between granitic and volcanic rocks; and

• Gold (+Ag) mineralization hosted by felsic volcanic rocks, such as the Chicago occurrence about 15 km southwest of the Boston deposit and the QSP area in the central portion of the property.

9. MINERALIZATION

9.1 BOSTON DEPOSIT

Gold mineralization at the Boston deposit is present in sub-vertical horizons of extensive hydrothermal alteration within a large iron-rich carbonate-altered shear zone. Organic carbon/graphite is a common component of the Boston mineralized system. Gold occurs within and around structurally controlled quartz-carbonate veins, which have been developed along lithologic contacts. Gold is associated with sulphide mineralization, mainly as clots of pyrite within the veins as well as in the wallrocks. Three major zones of gold mineralization have been identified. These are the B2, B3 and B4 Zones. Each zone extends over 1 km in length and is composed of numerous narrow quartz-carbonate veins with disseminated pyrite. The veins are 5 cm to 3 m in width and of variable lengths, within a 10 m to 40 m wide mineralized zone.

During the past year Miramar has reinterpreted the geology of the Boston area based on lithogeochemical data and detailed lithologic logging of recent deep diamond drilling, which tested the down plunge extensions of the mineralized shoots of the B2 Zone. Miramar now interprets that the various mineralized veins at Boston define the area near the hinge of a fold, with the B2 Zone on one limb, the B3 Zone in the core and the B4 Zone on the other limb, as illustrated by the schematic cross section (Figure 10). Figure 11 presents a longitudinal section for Boston.

B2 Zone

The B2 Zone is the most extensive mineralized unit of the Boston deposit. It has been drill tested to 1,000 m vertical and contains approximately 75% of the total Mineral Resources at Boston. It is characterized by a series of parallel, en-echelon quartz-carbonate veins along the contact between basaltic and sedimentary rocks. Individual veins are 20 cm to 3 m wide, extend up to 70 m along strike and are tightly folded about a fold axis plunging due south (McElroy, 1997a). Previously, the B2 Zone had been subdivided into three segments (panels), namely B2 North, B2 Central and B2 South.

Miramar underground in-fill drilling on a nominal 10 m x 15 m grid pattern defined a high-grade zone in the central portion of the zone. The B2 Zone has been subdivided into five sub-

zones. These are the 200, 210, 220, 240 and 260 lenses. These lenses extend 50 m to 70 m along strike and have been traced for approximately 300 m vertically. Mineralized intersections (of uncut gold values) range from 5.76 g Au/t over 2.2 m in Hole B348 to 277 g Au/t over 1.2 m in Hole B360. Mineralized intersections are often higher than 15 g Au/t over 2 m, including a wide intersection of 40.37 g Au/t over 23.12 m in Hole B270.

B3 Zone

Gold mineralization within the B3 Zone is present in an altered zone parallel to the B2 Zone, but is more erratic in size and shape than the B2 Zone. B3 comprises a stockwork of quartz-carbonate veins within basaltic rocks near the contact with ultramafic rocks. Mineralized intervals are marked by intense quartz-carbonate alteration – as veins associated with pyrite mineralization – and they occur in boudinaged lenses. Consequently, individual veins are irregular, up to 1 m wide and appear to have shorter strike lengths than the quartz-carbonate veins of the B2 horizon (McElroy, 1994 and 1997b). Nevertheless, based on 2000 drilling, this zone is interpreted to consist of six subzones. These are the 300, 310, 320, 330, 340 and 360 lenses.

B4 Zone

Gold mineralization within the B4 Zone is present at or near the contact between basaltic rocks to the west and sedimentary rocks to the east, some 100 m east of the B3 Zone. To date, only a limited amount of diamond drilling has tested this zone and the mode of mineralization is not yet well understood. The over-all structure of the Boston area, however, has been reinterpreted, as mentioned before and discussed in Section 7.2.2.

Table 2 presents several representative mineralized intersections from the Boston deposit. True lengths are generally 75% of core length.

9.2 DORIS DEPOSIT

9.2.1 GENERAL

The overall Doris (Lakeshore Vein) system comprises several sub-parallel veins traced for more than 5,000 m along strike and extending to depths of up to 400 m below the surface. Although mineralized throughout its extent, presently only two areas of concentrated gold mineralization have been defined and they are referred to as Doris North and Doris central. The Doris North resource area includes, from north to south, the Hinge Zone and the Connector Zone. The Doris central resource is located approximately 1 km south of the Doris Hinge Zone and is comprised of the Doris central and Stringer Zones. Additional mineralized veins are located west of and east of the main Lakeshore Vein system; these are known as West Valley Wall Veins and the Island Veins. The host rocks are basalts and lesser gabbros, which are variably carbonate (dolomite) altered and deformed. Little work has been completed on these narrower, more discontinuous structures.

Throughout the Doris Deposits and surrounding veins, visible gold is present with the highest gold grades within stylolitic, bull quartz veins. Coarse flecks of gold, locally with pyrite and occasionally with tourmaline, occur within discrete green-yellow, micaceous stylolites. Free gold grains also occur within bull quartz, preferentially near vein contacts and along discrete fractures. Sulphide content in the veins is typically low and averages less than 2% pyrite. Rare chalcopyrite is present locally. Grey- and chocolate-coloured sphalerite occurs locally with high-grade gold mineralization. Within the carbonate/paragonite altered shear zones, unmineralized fibrous quartz-dolomite ± tourmaline knots occur up to 10 cm across. Their irregular morphology suggests significant late stretching.

9.2.2 DORIS NORTH ZONE

The Doris North Zone extends from section 14025N to 15800N, a distance of some 1,775 m including the area about 450 m north of the northern end of Doris Lake called the Hinge Zone. The mineralization in the southern 550 m is referred to as the Connector Zone.

- 40 -

Watts, Griffis and McOuat

Hinge Zone

The Hinge Zone includes that portion of Doris North where the Central Vein and the Lakeshore Vein are joined at the crest of the isoclinal fold, as described and illustrated in Figure 7 above. The 2000 drilling was done to confirm the presence of the Hinge Zone, and the 2002 infill drilling focused on the delineation of the zone along sections spaced 12.5 m apart with drill intercepts every 10 m vertically. Results of the 2002 drilling demonstrated that the morphology of the folded quartz vein is more complex than the earlier interpretation. Based on these results, the Hinge Zone is interpreted to comprise three geologic domains. The southern two domains are separated from the northern domain by a left-lateral northwest trending brittle fault, named the Glacier Fault, with about 5 m of displacement. Another northwest trending fault, the Valley Fault, cuts the Hinge Zone at its northern end. The northern fault block is significantly thinner than the southern block. Gold grades increase toward the northern extremity of the zone. Generally the best gold grades occur within the central vein limb, and on the Central vein side of the Hinge crest. Contact metamorphism is present due to the proximity of a diabase sill, and remobilization of gold is considered to have contributed to the increased gold grades in this portion of the zone. Strong, pervasive magnetite and chlorite alteration overprints all rocks, with local fracture fillings in the quartz.

Multiple vein-bearing subparallel structures, referred to as the West Valley Wall veins, occur to the west of the Hinge. They generally strike north-south and dip about 60º to the west. The West Valley Wall alteration envelopes are generally three to four metres in width, with variable and generally weak quartz ± carbonate veining. Gold values are generally low, but anomalous.

Table 3 presents several representative mineralized intersections from the Doris North Zone. Hinge Zone true width is approximately 70-75% of core length for the limbs and approximately 95% for the immediate hinge area itself.

Watts, Griffis and McOuat

Connector Zone

Multiple phases of quartz ± carbonate veining associated with various episodes of alteration and strain occur at Doris, although only one appears to be associated with gold mineralization. At the Connector Zone, the best mineralization occurs within the C2 structure. The C2 occurs at the same stratigraphic position as the Central vein of the Hinge Zone to the north, but they are separate and distinct structures. This stratigraphic position occurs at the western contact of the core and Fe-rich basalt. Near 15075N there is an overlap between the Central vein and C2 vein. The C2 vein ranges from 1 to 10 m in width, averaging about 4 m. From north to south at the Connector zone, the C2 structure widens from a narrow discrete structure into a shear zone often exceeding 20 m in width at shallower levels. It is typified by 10 to 80% quartz veining, of varying age and composition. The C2 structure grades southward into the Stringer Zone at Doris central, which displays an identical style of mineralization. Gold is evenly distributed throughout C2, generally as free-milling grains. It is associated with 2-3% coarse-grained pyrite and traces of sphalerite and chalcopyrite in the highest grade zones. The size and grade of the C2 structure decreases significantly below the –120 m level in the Connector Zone area, although some high-grades have been intercepted to the north of 14550N within the C2 vein.

The Lakeshore Vein varies significantly in thickness at the Connector Zone, ranging from 1 to over 23 m. This variation occurs irregularly along both strike and dip. The vein itself is typified by bull quartz with irregular tourmaline septa, and commonly encapsulates strongly carbonate and sericite altered wall-rock fragments. Dolomite/sericite alteration occurs as 3-4 m wide selvages to the vein. Gold mineralization is associated with 1-5% pyrite, with the highest grades occurring as free-milling grains in quartz, often associated with narrow, light
yellow-green sericite partings. Highest grades occur along the hanging wall contact.

Multiple subparallel structures, referred to as the West Valley Wall set of shears, occur to the west of the C2 vein. They generally strike
north-south and dip about 60º to the west. The West Valley Wall shears are generally three to four metres in width, with variable and generally weak quartz ± carbonate veining. Gold values are generally low, but anomalous. It is interpreted that the high-grade subhorizontal shoot at the Connector zone is a result of the intersection between one of the easternmost West Valley Wall shears and the C2 vein. An alternate interpretation suggests that a late sill that follows an older structure may control mineralization.

9.2.3 DORIS CENTRAL ZONE

The Doris Central Zone lies approximately 1.2 km south of Doris North. Two styles of mineralization have been identified, the Lakeshore Vein and the Stringer Zone. The Stringer Zone lies up to 15 m west of but locally merges with the Lakeshore Vein. The Stringer Zone typically is a zone of veining in dolomite/sericite-altered basalts. Vein percentage in the Stringer Zone varies from 20 to 75%, although locally the zone can appear as a massive quartz vein. Vein size varies from centimetre to metre-scale veins. The Lakeshore Vein is typically a massive quartz vein, but occasionally can appear as a zone of veining typical of the Stringer Zone. In both zones, the presence of fine- to medium-grained subhedral to anhedral pyrite with the black stylolites is a good indicator of gold. The highest gold grades occur within stylolitic, bull quartz veins. Free gold grains also occur within cherty grey quartz, preferentially near vein contacts and along discrete fractures. Sulphide content in the veins is typically low and averages less than 2% pyrite. Rare chalcopyrite is locally zoned adjacent to strong gold mineralization. Grey- and chocolate-coloured sphalerite occurs locally with high-grade gold mineralization. Geological continuity is good, with variable, often high-grade gold intersections.

Table 4 presents several representative mineralized intersections from the Doris Central Zone. True lengths are generally 70% of core length.

9.3 MADRID DEPOSIT AREA

9.3.1 GENERAL

Gold mineralization at the Madrid area is hosted by sericitic and iron-carbonate altered iron and titanium rich basaltic rocks, and less commonly by gabbro, ultramafic rocks and interlayered argillaceous sedimentary rocks. Alteration minerals are albite, dolomite and quartz. Unlike the Doris Deposit, gold mineralization in the Madrid area is characterized by multistage brecciation and alteration with at least two separate gold mineralization events. Gold occurs within north-northeast, east, southeast and north-northwest trending brecciated and carbonate altered zones, and is associated with disseminated pyrite, which replaces brecciated mafic fragments. The deposit area comprises the Naartok West, Naartok East, Rand, Spur and Suluk Zones, all controlled by the DEFZ as described in Section 7 above.

The Madrid system consists of numerous bifurcating and/or intersecting zones of hydrothermal alteration and mineralization that develop in predicTable lithological settings and within proximity to the DEFZ. Mineralization is associated with pervasive alteration, which remains poorly understood, however, although the hydrothermal alteration assemblages are slightly variable with different mineralization horizons (i.e., Naartok West, Naartok East, Suluk) and host rocks, they are essentially represented by dolomite/ankerite, sericite/paragonite, silica, albite, hematite, and pyrite. An ongoing study to characterize the alteration in these areas began in 2005 to better understand the alteration processes and fluids associated with gold mineralization. The lenses reviewed in the study include the A1 lens, which is the main mineralized lens of Naartok East, the highly silicified Naartok West Z lens, and the Ye lens, which bridges the gap between these lenses (and which also may be an extension of the Naartok West Y lens). Lenses from the Rand and Suluk areas were also examined. More detailed descriptions of the main lenses are presented below.

The average composition for each of the zones was found to be fairly similar. For example, in the Madrid area, the most noTable difference is that the A1 lens has more sulphides than Z or Ye. In addition, the A1 lens demonstrates a much higher W content. These high W values may reflect a true geochemical difference or instead may reflect a discrepancy between different analytical laboratories, as the data for the A1 lens were obtained from BHP drill core assay results and may not be comparable to the ICP data for the other lenses, which were obtained by Miramar.

A modified Spider diagram was devised in order to provide a clear visual representation to highlight the differences between the geochemical signatures of each lens. For this diagram, the elemental averages from each resource lens were normalized to the composition of typical unaltered volcanic rocks. The unaltered compositions were taken from a general basaltic average, providing a level basis for inter-element comparison between the different zones.

The normalized data for each of the four areas (Naartok East, Naartok West, Rand and Suluk) display very similar trends. Each area shows strong enrichments in Au and As and lesser enrichments in Ag, S, Cu, Mo. There is essentially no difference in Zn, Mo, Pb and Ba. Some areas show elevated Ni, Co, and Cr, but these enrichments are likely a result of their association with basalts that have a primary enrichment in these elements compared to the normalizing basalt.

The most pronounced differences between the four areas are manifested in Hg and W. Naartok East, Rand and Suluk demonstrate significant enrichments in W and Hg, whereas Naartok West does not have a significant enrichment in W and Hg. This relationship suggests that the Naartok West area may represent a slightly different mineralized system.

The main zones of the Madrid area and the mineralized lenses are described below.

9.3.2 NAARTOK WEST ZONE – Y & Z LENSES

The Naartok West Zone consists of two main mineralized lenses, each with a lateral east-west strike length of approximately 350 m, between 433000E and 433350E. These two mineralized lenses have been labelled the Y and Z lenses. The Z lens comprises the lower structural/stratigraphic lens, which sits in the immediate hanging wall of the DEFZ. The Y lens lies within the hanging wall of the Z lens. In general, the Y lens is less continuous and is associated with a weaker tenor of mineralization.

The Z lens lithology is very distinctive in the core as it exhibits a cryptocrystalline texture, resulting from strong silicification and albitization. All primary volcanic textures are obliterated. Visually, the Z lens is translucent grey to brown to white in colour and has a “dirty-looking” appearance likely due to fine grained disseminated sulphides and gold. Gold-

bearing quartz ± carbonate veins at or near the hanging wall contact with the DEFZ are commonly associated with the lens.

The Y lens is defined as a zone of strongly altered brecciated basalt with a common but variable sedimentary component. The lens is characterized by strong sericite-paragonite and iron carbonate alteration, with mm to cm scale quartz veins. Overprinting these veins are secondary quartz-dolomite veins that form a “crackle breccia” texture, which is associated with this zone. Visible gold is commonly observed within the narrow quartz–dolomite veinlets and within an earlier veining phase. Pyrite content is variable and is positively correlated with gold mineralization. Pyrite is commonly observed as fine-grained disseminations within the basalt, to subeuhedral and medium grained within the quartz veining. Larger (<1 m) gold-bearing white quartz veins are also associated with the Y lens.

Figure 12 shows a longitudinal section of Naartok West.

9.3.2 NAARTOK EAST ZONE – A1 & YE LENSES

The Naartok East A1 and Ye lenses have a NNE strike with a moderate NW dip and are located approximately between 433350E and 433600E. Both lenses are very similar with only a few visually noTable differences.

The A1 lens, formerly known as the Perrin zone, is a distinctive zone of strong alteration, brecciation and sulphidation. The zone has strong sericite-paragonite and dolomite alteration with local silicification and albitization. As in the Naartok West Zone, mineralization occurs

in moderately to strongly brecciated rocks. The brecciated volcanic clasts exhibit a moderate to strong sericite-dolomite alteration ± albite ± silica within a strongly dolomitic matrix. Generally the upper portion of the zone is hosted in an altered and brecciated variolitic volcanic unit, grading downwards into a weak to moderately strained non-variolitic suite of moderate to strong “crackle breccia” textured basalt that has heavily disseminated fine-gained pyrite (usually 5–25%) and local associated siliceous zones. The lens is commonly bounded on the footwall side by strongly silicified argillite, which also represents a possible structure. The argillite is in turn underlain by dark green ultramafics and flow breccias. Visible gold is rare, however, it has been observed within the small mm to cm scale silica ± albite ± dolomite veins. The overall gold tenor for the A1 lens is lower than for the other zones at Naartok.

The Ye lens is the most recently discovered mineralized zone of the Naartok system. This lens is almost identical to its counterpart, the A1 lens. The noTable exception is that the Ye lens is approximately 75 to 100 m vertically lower, which is possibly related to a fault offset. The Ye lens is observed in drill core to be moderately to strongly brecciated, with a higher silica-albite component. Gold grades are significantly higher than in the A1 lens, however, on the whole, the alteration assemblages and primary host rocks are very similar between the Ye and A1 lenses. Another distinctive feature of the Ye lens is the stronger hematite content in comparison to the A1 lens. This hematite alteration forms a strong salmon-pink colouration. The footwall to the Ye lens comprises weakly strained, massive and commonly fuchsitic basalt.

9.3.3 RAND ZONE

The Rand Zone is roughly west striking and north dipping and occurs east of the Naartok East Zone. Rand mineralization is hosted within A-type (Fe-Ti) volcanics, gabbros and graphitic argillite rocks, which are weakly to strongly brecciated. The Rand Zone is similar to the Naartok East A1 lens with respect to its moderate to strong sericite/dolomite ± albite ± silica alteration and pyrite percentage. Like the Naartok East Zone, in particular the A1 lens, the Rand Zone is always terminated at a strongly siliceous, and sometimes graphitic, argillite.

Figure 15 shows a longitudinal section of the Rand Zone.

9.3.4 RAND SPUR ZONE

The Rand Spur mineralized area is situated north of the Suluk and Rand Zones and east of the Naartok East Zone. Stratigraphically it sits in a similar position as the Suluk T2 zones, however, is more weakly mineralized. This area has received only limited drill testing.

9.3.5 SULUK ZONE

The Suluk Zone is located southeast of Rand. It is situated adjacent to and east of the DEFZ near the western shore of Patch Lake. Based on 2001 drilling results, the zone was interpreted to consist of two parallel mineralized lenses. Recent compilation, however, suggests a facies change in the host basalts and that the two lenses represent one mineralized zone, with the main zone joining with the upper (and thicker) zone.

By the start of the 2003 program four lenses had been defined in the Suluk area based on linking grade; following recognition of geological controls and stratigraphic re-interpretation along with the results of the 2003 program the lenses were further refined. The lenses were defined by the rock packages that controlled them. The T1 Horizon consists of mineralization immediately adjacent to or within the deformation zone, the T2_HW or west lens consists of pyrite mineralization associated with dolomite/silica/sericite alteration with local wormy sub-centimetre locally hematite-bearing veins. Visible gold sometimes occurs within these veins. The major mineralized lens is the T2_FW or central lens (intersected in 2004 with drillhole 04PMD250). This is a brecciated and silica/sericite/dolomite-flooded mafic volcanic and

mixed volcaniclastic zone, with the host rocks replaced by locally up to 40% very fine-grained pyrite. This Fe-Ti tholeiitic flow is bounded by black argillite interflow/intraflow sediments to the west and a visually distinct spilitized flow (P.G.P.) to the east. The easternmost lens is the T3 lens, which is very similar in character to the T2 lenses but is more poorly developed and less explored (intersected in 2004 with drillholes 04PMD244 and 04PMD247). The T3 zone is characterized by numerous flow sequences of variolitic basalt, pillowed basalt, massive basalt and ultramafic rocks sporadically intercalated with moderately to strongly altered volcaniclastic packages with argillaceous material. Minor graphitic argillite lenses are also common within the T3 package of Patch Group volcanic rocks. The zone itself is proximal to the eastern P.G.P. contact, similar to the T2_FW along the western P.G.P. contact, and has mineralized under brittle deformation conditions. The T3 lens is variable in thickness, has moderate to strong sericite/dolomite alteration with weak silica and weak to moderate pyrite mineralization (usually 1-5%). Visible gold is rare.

The Suluk Mineral Resource reported by Miramar at the end of 2002 and reviewed by RPA, was a polygonal based estimation focusing on higher grade mineralization and utilized a 7 g Au/t cutoff grade. The total Inferred Mineral Resource reported was 1,475,000 tonnes grading 12 to 13 g Au/t containing 580,000 ounces. The Suluk resource represented 13% of the total Hope Bay Mineral Resources as of December 31, 2002.

Following the 2003 drilling, a block model was created and reviewed by RPA in January 2004 prior to the Mineral Resource press release of January 2004. The Suluk Mineral Resource was estimated for a range of cutoff grades from 1.0 to 10.0 g Au/t. Miramar used the 5 g Au/t cutoff figure for reporting purposes and reported an Indicated Mineral Resource of 527,000 tonnes grading 8.2 g Au/t containing 138,000 ounces of gold and an additional Inferred Mineral Resource of 3,615,000 tonnes grading 6.3 g Au/t containing 751,000 ounces of gold.

At that time the Suluk Zones were recognized as being part of a continuous system of mineralization and as such were reported as part of the greater Madrid area Mineral Resource. The Suluk portion represented 16% of the total Hope Bay Mineral Resources as of December 31, 2003.

There was no significant drilling at Suluk in 2004 and 2005 and no new or revised Mineral Resource estimations have been made since the initial reporting in January 2004 and review

at that time by RPA. The Mineral Resource press release made by Miramar in February 2005 reported Suluk resources using a lower cutoff of 2 g Au/t to correspond with that used for reporting the overall Madrid area Mineral Resources. The Suluk Mineral Resource increased to an Indicated Mineral Resource of 1,125,300 tonnes grading 4.2 g Au/t containing 152,500 ounces of gold and an additional Inferred Mineral Resource of 14,559,600 tonnes grading 4.0 g Au/t containing 1,889,600 ounces of gold. The Suluk deposit represents 23% of the total Miramar Hope Bay Mineral Resource as of December 31, 2005.

Figures 16 and 17 present a schematic cross section and a longitudinal section of Suluk respectively.

Table 7 presents several representative mineralized intersections from the Suluk Zone. True lengths are generally 60% to 75% of core length.

9.3.6 PATCH 14 ZONE

Patch 14 is an additional area of defined mineralization in the Madrid trend and is located adjacent to the DEFZ approximately 4 km south of the Suluk Zone. Mineralization is hosted within a zone of moderately to strongly carbonate-sericite altered, mafic volcanics and narrow intermediate porphyry dykes (Wolverine porphyry dykes). This moderately to strongly strained zone is wedged between two wider (+20 m) thick dykes of porphyry. Mineralization occurs as visible gold and disseminated pyrite, hosted within massive bull quartz and quartz-carbonate veins. At least three sub-parallel veins have been identified and exhibit a north-south strike and steep (80º) dip to the west.

The most significant structure of Patch 14, the West vein, has been traced discontinuously along strike for 400 m, however, the mineralized portion has only about a 100 m strike extent. The East vein extends for about 80 m along strike, but has much less vertical extent. Mineralization is open down a steep southerly plunge (about 70º), and along strike at depth. Drilling to the 300 m level below the bottom of Patch Lake has intersected multiple veins and gold mineralization. The main quartz lenses and corresponding grade-thickness contours at Patch 14 appear to define steep southerly plunging bodies. Although the strike extent of the mineralized zones appears to be limited, the down dip and plunge extensions of the quartz veining appear to be open.

10. EXPLORATION

10.1 2000

The Miramar/Hope Bay Gold Corp Inc. (“HBGC,” successor to Cambiex) joint venture (“HBJV”) commenced a major exploration program on the Boston and Doris Deposits in 2000 and for the entire project area, some 45,580.1 m of diamond drilling in 319 holes were Completed.

The Boston ramp/decline was dewatered and 16,024.3 m were drilled in 145 holes of detailed in-fill underground drilling on a nominal 10 m by 15 m spacing. The drilling was carried out by Advanced Diamond Drilling of Surrey, B.C. This work further defined a high-grade trend in the central portion of the B2 Zone. A small number of these holes tested various possible vein orientations in the B3 Zone. Twenty surface holes totaling 3,927.6 m were drilled at Boston.

Drilling at Doris concentrated on the Hinge Zone on what became Doris North and Doris central and on Doris connector. Diamond drilling totaled 23,460.1 m in 142 holes.

Drilling in the Madrid area totaled 2,168.1 m in 12 holes.

Details of meterage, type of drilling and number of holes by year and general location is
Provided in Section 11.

10.2 2001

The HBJV completed 35,044.4 m of diamond drilling in 356 holes and 5,008.6 m of reverse circulation (“RC”) drilling in 154 holes.

The HBJV discovered two new zones in the Madrid area, the Suluk and Naartok and completed infill drilling on the Boston deposit and the Doris connector resource. A small amount of diamond drilling was carried out elsewhere on Madrid. The RC drilling concentrated on Madrid outside of the resource areas and on regional targets over the entire project area.

- 58 -

Watts, Griffis and McOuat

In addition, the HBJV carried out till surveys and detailed mapping and various lithogeochemical and other research projects.

10.3 2002

Miramar acquired 100% ownership of the project in a stock transaction with HBGC and completed 24,594.2 m of diamond drilling in 286 holes and 4,911.4 m of RC drilling in 38 holes. In addition, nineteen condemnation and geotechnical diamond drillholes totaling 752.0 m were drilled on Doris connector.

Diamond drilling concentrated on Doris Hinge, Madrid outside of resource areas and regional targets. RC drilling concentrated on Madrid outside of resource areas and regional targets.

Miramar contractor Frontier Geosciences of North Vancouver carried out seismic refraction surveys on the Twin Peaks (Maximus option), North Windy, Gas Cache and Nexus areas. In the case of Nexus, a bedrock seismic velocity model was generated in order to assist in interpreting alteration and structural corridors.

Heavy mineral separates till sampling was undertaken in the Doris, North Madrid and Daiwa areas. Samples in the North Madrid area indicated potential for additional resources based on gold grain morphology and assumed travel distance of the grains. In the Daiwa area, a number of unexplained anomalous till samples was returned.

Lithogeochemical studies of the existing whole rock database and new samples collected from the drilling and mapping programs were used to design a Hope Bay rock classification scheme, which was subsequently used to screen unknown samples.

Baseline environmental surveys were carried out as part of permitting activities.

10.4 2003

In 2003, Miramar completed 43,238.3 m of diamond drilling in 169 holes and 1,808.8 m of RC drilling in 82 holes. In addition, eight condemnation and geotechnical diamond drillholes totaling 252.3 m were drilled on Doris Hinge, seven geotechnical diamond drillholes totaling

- 59 -

Watts, Griffis and McOuat

264.3 m were drilled on Doris connector and seven geotechnical diamond drillholes totaling 181.5 m were drilled on Doris central.

Deep drilling targeting the Boston deposit extended mineralization to approximately 1,000 m below surface and 600 m on strike and a surface re-mapping program was completed and generated a revised working model for the deposit. The highlight was an intersection of 54.5 g Au/t over 9.0 m true width in hole S03-293 at over 1,000 m vertical on the B2 Zone.

Elsewhere diamond drilling was concentrated on the Madrid Suluk resource area, doubling the depth extent and confirming a revised geological interpretation. Elsewhere on Madrid, diamond drilling tested mineralized zones in structures and splays parallel to or adjacent to the Deformation Zone in the Patch/Rand areas. Two holes were drilled on Doris connector and several regional targets were drilled.

RC drilling concentrated on Madrid outside the resource areas and on regional showings/target areas, including South Nexus, Gas Cache and Boston NE, all of which demonstrated potential to host significant gold mineralization.

Twelve regional targets, including those RC drilled, were the subject of regional mapping and geophysical programs. Miramar carried out detailed geophysical surveys, ground magnetics by Aurora Geosciences Ltd. of Yellowknife, NWT and an E-Scan conductivity survey by Premier Geophysics of Aurora, Ontario, over certain areas and conducted various lithogeochemical and other research projects.

A draft environmental impact statement (“EIS”) for the Doris North Deposit was submitted to the Nunavut Impact Review Board (“NIRB”) in early 2003. Permitting activities continued throughout the year.

10.5 2004

Miramar completed 43,447.5 m of diamond drilling in 86 holes and 1,577.4 m of RC drilling in 86 holes. In addition, six geotechnical diamond drillholes totaling 290.9 m were drilled on Doris Hinge.

- 60 -

Watts, Griffis and McOuat

Diamond drilling was concentrated on Madrid Naartok where the resource area was expanded. Further drilling was carried out at Boston and a small number of holes was drilled at Doris Hinge and Madrid Suluk and Rand. The RC drilling was concentrated on Madrid outside the resource areas and on regional targets.

Miramar also carried out detailed mapping and various lithogeochemical and other research projects.

Permitting studies and activities continued and the formal Doris North EIS was submitted to NIRB late in the year. It was returned with a request for additional studies and information.

10.6 2005

Miramar completed 33,197.70 m of diamond drilling in 133 holes. In addition, six geotechnical diamond drillholes totaling 66.3 m were drilled on Doris connector. There was no RC drilling.

Drilling was concentrated on the Madrid Naartok Zone and added to the resource base. A small number of holes was drilled elsewhere on the Madrid Trend and on regional targets, which included the North and South Nexus areas on the southern portion of the Madrid Trend, at West Kink and the Eastern Contact and Twin Peaks areas on portions of the property optioned to Maximus. In addition, infill drilling was carried out to upgrade resources in the Doris Central Zone.

Aurora Geosciences Ltd., of Yellowknife carried out 18 km of Induced Polarization surveying over portions of the Madrid area and the Kink and Nexus areas. In addition, Miramar carried out mapping, prospecting and various lithogeochemical, thin section and other research projects.

The Doris North Project EIS was re-submitted to the NIRB.

10.7 2006 — ONGOING AND PLANNED ACTIVITIES

On March 6, 2006, the NIRB recommended to the Minister of Indian and Northern Affairs Canada that the Doris North Project proceed. Once this recommendation is accepted by the Minister, the NIRB can issue a project certificate.

- 61 -

Watts, Griffis and McOuat

The 2006 program began March 1 with camp opening and supply haulage and diamond drilling commenced March 11. At the time of the WGM site visit, 6 diamond drills were in operation. To April 30, 2006, 40 holes totalling 11,934.2 were completed. Twelve holes were completed on Doris connector and Doris central, with the remainder on Madrid.

On May 25 and June 20, 2006, Miramar issued press releases providing updates on the 2006 drilling program and other activities on the property. Assay results for 32 holes on Suluk/South Suluk, Rand and Doris North Connector were released on May 25 and Miramar reported results for a further 22 holes on Suluk, Rand and South Suluk, and that to June 20, some 83 holes totalling 26,500 m had been drilled to date in 2006. Results continue to be encouraging, and are typical of historic representative intersections quoted in Section 9.

Miramar has budgeted $31 million towards approximately 55,300 m of drilling, ongoing permitting activities for Doris North and development activities designed to, amongst other things, determine the size of a second development phase to follow Doris North. Conceptually this second larger phase of development would incorporate material from the Doris Central and upper portions of the Madrid and Boston deposits. Kitnuna Constructions of Cambridge Bay and Steffen Robertson and Kirsten (Canada) Inc. (“SRK”), Golder and Associates and AMEC Americas, all of Vancouver, have provided and are providing services on various aspects of the Doris North Project.

Early in the winter program, a Ground Penetrating Radar survey was carried out over the land portion of the Madrid Deposit Area by Aurora Geosciences Ltd., of Yellowknife. Ground magnetic surveys totalling 1,500 km have been carried out over selected areas of the property by Clearview Geophysics Ltd. of Brampton, Ontario.

Ongoing research projects, as part of two M.Sc. studies, are examining the petrology of altered zones and mineralized lenses, and lithogeochemical screening of data.

On April 20, Miramar issued a press release documenting the in-house prepared Mineral Resource estimates as of December 31, 2005 for all the Hope Bay Project deposits.

11. DRILLING

11.1 GENERAL

WGM has not reviewed the drilling practices and details of the large amount of historic drilling carried out by BHP and the small amount carried out by Noranda. Based on its knowledge of these companies, it is WGM’s opinion that this historic drilling would have been carried out by reliable contractors employing industry standards common at the time.

With the exception of the 2000 underground drilling at Boston, which was carried out by Advanced Diamond Drilling of Surrey, B.C., all the Miramar drilling programs have been carried out by Major Drilling Group International Inc. (“Major”), headquartered in Moncton, N.B. The Hope Bay program is directly supervised and supported by Major’s Yellowknife office.

Drilling is carried out 24 hours a day, seven days a week from as early as March until as late as September and crews are rotated in and out of camp on a regular basis. Major has an onsite shop and supply centre and Miramar provides the camp and logistical services. At the time of writing this report, there were six diamond drills operating. There is a variety of drill types but all core is NQ2 sized (~50.7 mm in diameter).

An RC drilling rig purchased by Miramar arrived on site in late April, however, it is unlikely to see any use during the 2006 program. Reverse circulation drilling completed between 1998 and 2004 was carried out by Major and JT Thomas Drilling of Smithers, B.C. (subsequently purchased by Major in 2001). The RC drill rigs were capable of drilling only vertical holes with the exception of the 2001 program when rigs had the capability of completing angled holes.

Miramar and historic drilling details for the property to April 30, 2006 are summarized in Table 8.

11.2 HOLE COLLAR AND DOWN-HOLE ATTITUDE SURVEYS

All drillhole collars are established by total station surveying carried out by a Miramar contract surveyor. The head angle is also generally set by the surveyor. Once coring is underway the surveyor surveys the drill stem to determine that the dip and azimuth are acceptable in the circumstances. For most holes, at 30 m into bedrock a Maxibor survey is carried out by Miramar geotechnical/surveying staff. Again, depending on circumstances, the hole may be allowed to proceed or may be recollared. Another Maxibor survey is carried out at approximately 175 m for infill holes and a final Maxibor survey is carried out at the bottom of all holes. The drillers carry out a Reflex EZ-Shot dip survey every 50 m and generally at the end of each shift.

RC drill collars were laid out and surveyed post-drilling using a differential GPS system. No down-hole surveying was completed to determine true dips of vertical holes; an inclinometer was utilized on angled holes to estimate hole inclination.

11.3 CORE HANDLING AND LOGGING PROTOCOLS

Miramar has developed a comprehensive set of protocols that are reviewed and revised as appropriate based on recent-past in-house experience and developments elsewhere in the industry in similar environments. Geotechnical and geological logging data are recorded on Palm Pilots and laptops. Miramar has a young but competent and dedicated group of geologists and several geotechnicians, who receive excellent training on site. Generally new geological hires begin with geotechnical logging then move to geological logging, each geologist taking full responsibility for one drill and on call to monitor hole progress and for hole shut down 24 hours per day.

There is an 82 page manual documenting the protocols. WGM has reviewed the manual and prepared the following brief summary of the highlights:

Geotechnical Logging Protocols

1.	Core is laid out, cleaned and blocks inspected;
2.	Draw metre marks on the core with a black permanent marker and record Core Recovery into the Palm pilot;
3.	Measure RQD length and RQD%;

- 66 -

Watts, Griffis and McOuat

4.	Measure Magnetic Susceptibility of core;
5.	Measure Specific Gravity (“SG”) of hanging wall, mineralized, and footwall zones. SG is determined on a 5-7 cm representative length of core by the “weighing in air, weighing in water” method without wax immersion;
6.	On request of logging geologist, draw orientated core lines on core with permanent marker;
7.	Label each core box. At this point core is geologically logged; then
8.	Photograph the core;
9.	Sampled core boxes are moved to the splitters’ shack and other core boxes are stacked outside;
10.	Compile data on the server;
11.	On request of logging geologist (detailed geotech log) – Measure Internal Rock Strength; and
12.	On request of logging geologist (detailed geotech log) – Describe different joint sets.

Geological Logging

Logging focuses on the collection of lithological, structural, and mineralogical parameters, as well as veining relationships and alteration intensity, which have a suspected or demonstrated relationship to gold mineralization. Data are entered into an Access database, with parameters largely described using pick-lists developed for each deposit or zone and there are areas available for free-form descriptions as appropriate. The geologist is responsible for marking the core for sampling and assigning sample numbers using three-part sample tickets as described further in Section 12 below.

A similar manual exists for each season of RC drilling (2001-2004) documenting planned projects and all procedures related to working on the RC drill from locating collars through chip logging, sampling and site clean-up. WGM has not reviewed this manual.

12. SAMPLING METHOD AND APPROACH

WGM has not reviewed the practices employed by historic operators, mainly BHP. Based on its knowledge of BHP and the general quality of its work, it is WGM’s opinion that BHP’s practices would have met or exceeded industry standards at the time. The remainder of this section describes Miramar practices.

The logging geologist chooses the areas to be sampled and marks the beginning and end of each sample on the core box and the core, and draws a line along the sample length indicating how the sample is to be split. He or she places two parts of a three-part numbered paper sample tag, on which basic information, including assaying/analytical instructions are marked, in the box at the end of the sample. For security reasons, neither hole number nor meterage is marked on these tags. The third portion of the tag, which does record hole number and meterage, stays in the sample tag book. The sample number is also written on the core. Samples are a minimum of 0.3 m in length, a maximum of 1.5 m and must not straddle lithological contacts, vein contacts or alteration fronts. One metre shoulder samples are taken on both the footwall and hanging wall of the mineralized areas.

The logging geologist is responsible for choosing the appropriate commercial standard for insertion into the sample stream. There must be one standard inserted in each batch of 20 samples. He or she also prepares the numbered sample tag in the manner described above, places a portion of the tag along with the standard in a plastic sample bag, writes the sample number on the bag and passes this bag on to the sample splitters/geotechnicians who ensure that the standard sample gets into the sample stream in the proper sequence. One blank sample (using locally derived sawed diabase core to disguise it as much as possible) is also included in each batch of 20 samples. The blank is often inserted immediately after highly mineralized samples to test for contamination during sample preparation at the laboratory.

Following logging, the core is photographed then passed on to the samplers. One of the two numbered tags is placed in a plastic sample bag and the same sample number is written on the bag. The sample is then diamond sawed as per the core markings, one half going into the bag and the other returned to the box and retained for future reference and further testwork as required. Once splitting of a sample is complete, the second portion of the sample tag is stapled to the core box at the end of the sample in question. The plastic bags are sealed with zap straps (plastic straps used by tradespeople to bundle wires, etc.), and put into rice bags holding a maximum of

- 68 -

Watts, Griffis and McOuat

22.6 kg to avoid excess air cargo charges. Individual rice bags contain only samples from a specific hole or portion of a hole and shipments comprise complete holes only. Shipments are flown to Yellowknife on Miramar charter aircraft.

Following is “Sampling” information related to RC drilling as taken from Miramar documentation.

“CHIP SAMPLE COLLECTION. Holes are to be drilled vertically. Dry drilling will be utilized with material collected every 2.5 feet (4 samples per rod) with the final sample in the vertical holes being a composite 10-foot test of bedrock. Representative samples of every 2.5 ft of bedrock will be collected in bags labelled with the hole number and footage and stored at base camp. Samples from the cyclone are to be collected in 5 gallon buckets (25 buckets, 1 set with 5 spares). Cleaning the buckets consists of dumping the remaining cuttings either in a single pile close to the collar or scattered about the working area. Muds are easily removed after letting the material freeze. Upon completion of a hole the rig tows the shack to the next set-up. The hole will be picketed and identified for later survey by GPS.

“SAMPLING. Representative: Each 2.5 foot interval in bedrock is to have a representative sample collected and labelled with the hole number and footage. These samples will be stored at base camp. Geochemical: Intervals to be assayed are given a unique sample number from a sample book. Two samples will be collected per vertical hole, one till sample and one bedrock sample. ‘Basal’ till samples (10 kg, ~2.5 ft run) will be collected from the till located at the bedrock-overburden interface. Bedrock samples will be split using a riffle splitter to arrive at a 1kg representative sample for geochemical assay, the paired split will be retained as a reference sample. The reference sample will be used for carbonate alteration staining (see section Sample Handling and Appendix B) and allow for re-assays if required.

“STANDARDS AND DUPLICATES. In every 20 assay samples taken at least one standard and one duplicate sample will be collected. The low standards (IME02UN) will be used; two packages are required for adequate amounts of material for a fire assay. A suggestion for tracking this is to pre-label sample books with an alternating standard or duplicate every 20 tags and pre-bagging the standard with the sample tag.

“CHIP TRAYS. A summary of each hole will be kept in chip trays labelled with the hole ID and footage. Overburden samples can be grouped by lithology and may span from 2.5 to 60+ feet for a single chip tray compartment. Every 2.5 feet of bedrock should be represented by a single chip tray compartment providing an accurate summary of the hole.

“SAMPLE HANDLING. Upon return from shift, in addition to data entry, samples collected for assay will be placed in the sample storage tent in the appropriate bag,

- 69 -

Watts, Griffis and McOuat

one for tills and one for rocks. Till samples will be sent to Overburden Drilling Management for gold grain picking. A 0.5kg sample of till with coarse material sifted out will also be sent to TSL for assay. Rock samples are to be assayed at TSL labs for 32 element analysis and gold. Bedrock samples will also receive a whole rock analysis package to aid in lithological and alteration identification.

“The representative samples from each 2.5ft in bedrock and the assay sample duplicate will be stored in an area to be determined at base camp.”

13. SAMPLE PREPARATION, TESTWORK AND ANALYSIS, AND SECURITY

13.1 HISTORICAL AND GENERAL INFORMATION

WGM has not reviewed the practices employed by historic operators, mainly BHP. Based on its knowledge of BHP and the general quality of its work, it is WGM’s opinion that BHP’s practices would have met or exceeded industry standards at the time. The remainder of this section describes Miramar practices.

Information regarding sample shipments is generated in the field and forwarded by e-mail to Discovery Mining Services Limited (“Discovery”), which acts as expeditor for Miramar, in Yellowknife and ALS Chemex and Miramar in North Vancouver. This enables cross checking of sample shipments during transportation and on their receipt at the laboratory, and the timely reporting and rectification of discrepancies, if any.

Until 2006, Miramar used the services of TSL Laboratories Inc. (“TSL”) in Saskatoon, Saskatchewan, as the primary laboratory with ALS Chemex (“ALS Chemex”) of North Vancouver providing check analytical services. The 2006 program utilizes ALS Chemex as the primary laboratory and TSL to carry out check analyses as part of the Miramar Quality Assurance/Quality Control (“QA/QC”) program. ALS Chemex has attained ISO 9001:2000 and ISO/IEC Standard 17025 accreditation. TSL has attained ISO/IEC Standard 17025 accreditation.

13.2 SAMPLE PREPARATION

All sample preparation activities are undertaken in the analytical laboratory and a summary is as follows:

• Samples are dried and jaw crushed to 95% passing through a 10 mesh sieve (1.70 mm);

• A 1,000 g split is riffled off and the remainder is stored at the laboratory as a coarse reject;

• For samples with a total weight less than 1,000 g, the total sample is taken and there is no reject left over;

• The entire 1,000 g split is pulverized to 95% passing 150 mesh (106 microns):

o The pulverizer is cleaned with silica sand after every sample;

- 71 -

Watts, Griffis and McOuat

• The sample is placed on a mat, homogenized and sub-samples taken:

o 2 assay ton (58.3 g) sub-sample for fire assay;

o 5 g sub-sample for ICP scan when requested;

o The unused pulp is stored;

• Should the fire assay be + 20 g Au/t, visible gold be seen in the core sample or the logging geologist suspect high gold content, a screen metallic assay is carried out also:

o This process starts with a new 1,000 g pulp being sieved through a 150 mesh screen;

o The entire +150 mesh fraction is subjected to fire assaying with a gravimetric finish, being split into two (or more) equal parts to do so should the portion be more than 50 g; and

o A 2 assay ton sub-sample of the –150 mesh portion is subjected to fire assaying with a gravimetric finish.

13.3 ANALYSIS

As noted above and with the exception of surface rock and a few other samples, all gold assaying is by fire assay with a gravimetric finish on 2 assay ton sub-samples (ALS Chemex procedure Au-GRA22). Surface rock sample and RC chip sample golds are determined by fire assay with an Atomic Absorption (“AA”) finish on 50 g sub-samples, 0.005–10 ppm (ALS Chemex procedure Au-AA24). Screen metallic fire assay (Au 0.05 to 1,000 ppm) is performed on a 1,000 g sample split, which is screened to 100 micron. Duplicate assays are complete on the undersize fraction (2 assay ton) and an assay on the entire oversize fraction (ALS Chemex procedure Au-SCR21).

Whole rock analysis and/or trace element analysis is carried out on a certain number of core and samples. A prepared sample (1.000 g) is added to lithium tetraborate flux (9.000 g), mixed well and fused in a furnace at 1,100°C. A flat glass disc is prepared from the resulting melt. This disc is then analyzed by X-ray fluorescence spectrometry. Oxide concentration is calculated from the determined elemental concentration and the result is reported in that format.

A prepared sample (0.200 g) is added to lithium metaborate flux (0.90 g), mixed well and fused in a furnace at 1,050°C. The resulting melt is then cooled and dissolved in 100 ml of 4% nitric acid. This solution is then analyzed by inductively coupled plasma – mass spectrometry (“ICP_MS”).

13.4 QUALITY ASSURANCE/QUALITY CONTROL

13.4.1 GENERAL

Miramar has a comprehensive QA/QC program in place that in WGM’s opinion meets industry standards. The program includes provision for the re-assaying of sample batches under certain circumstances as described in Section 13.4.2. There are exceptions to these circumstances and it is WGM’s opinion that the QA/QC program would be enhanced if exceptions were eliminated.

13.4.2 STANDARDS AND BLANKS

Commercial standards and field blanks (one of each per batch of 20 drill core samples as described in Section 12) are inserted into the sample stream in the field and the results of these assays are monitored and the database updated on an ongoing basis. Should any standard return a value more than two standard deviations from its expected value, that sample and all the samples in that batch are reassayed. The batch may not be re-assayed in cases where sample values in the batch are below the detection limit or if the sample population for a new standard is too small to provide a representative mean value. Miramar has not collected duplicate core samples. BHP did so in the 1997 and 1998 programs on Doris. Duplicate samples were collected by Miramar for RC chips during the sample splitting procedure.

The commercial laboratories used by Miramar have their own internal QA/QC protocols involving the use of standards and blanks.

During 2005 Miramar used nine standards, varying in expected gold content from 1.48 g/t to 15.52 g/t. Four of these were commercial standards acquired from International Metallurgical and Environmental Inc. (“IME”) in 2001 and 2002, one was the last of several prepared for Miramar via a round-robin process by ALS Chemex in 2004, and the other four were commercially prepared ones acquired from CDN Resources in 2004 for use in 2005 as the others were depleted.

- 73 -

Watts, Griffis and McOuat

For the 2006 program, a new set of four standards was acquired from Ore Research & Exploration Pty Ltd in Australia. The standards were prepared in 2003 and 2004 using industry standard round-robin protocols involving laboratories in several countries. Recommended gold values are 0.72 g/t, 3.36 g/t, 9.64 g/t and 11.33 g/t.

13.4.3 THIRD PARTY CHECK ASSAYING

In 2004, the combined total of all QA/QC samples (exclusive of internal laboratory samples) was approximately 24% of the entire Miramar drill core sample stream. This included approximately 15% duplicate coarse rejects sent by TSL to ALS Chemex where they were prepared and analyzed using the same protocols as TSL. In 2005, the total was reduced to 15% of which 5% were duplicate rejects check assayed by ALS Chemex.

In 2006, Miramar is again check assaying 5% of its coarse rejects, however, ALS Chemex as the primary laboratory is now shipping the rejects to TSL for check assaying.

13.4.4 QA/QC RESULTS 2005

Standards

Over the course of the 2005 program 421 standards were assayed. Of these, 10 returned values out of the acceptable range and of these, three, along with the remaining samples in that batch were re-assayed. The remaining seven were not re-assayed since either the standard sample population was too small or the batch was composed of samples which had nominal or below detection limit values.

Blanks

During the course of the 2005 program 495 blanks were assayed and of these one returned a value slightly above the lower detection limit of 0.03 g Au/t. The five samples following the standard were re-assayed.

TSL Standards

TSL assayed 636 standards as part of its internal laboratory QA/QC. Miramar reported that four of these returned values out of the acceptable range. All quality controls outside of two standard deviations were either repeated or selectively confirmed

Watts, Griffis and McOuat

ALS Chemex Check Assaying

To compare the check assay results, the data are compared using a t-statistic for paired data. The rationale for this methodology is that for geochemical analysis, duplicate analyses are not expected to return the same value due to the nature of gold distribution, however, the mathematical difference between two duplicate analyses on average should fluctuate about zero. Some of the duplicate analyses should be higher and some lower, but on average the difference should be zero, if the data sets are consistent.

To test this, the mean numerical difference between assays at TSL and ALS Chemex was calculated. This mean was calculated at a 90% confidence interval (“CI”) which gives a range for the mean. If the range includes zero then the datasets are derived from the same population and the data is considered consistent. If zero falls within the 90% CI then the datasets are derived from the same population at a 90% confidence interval. If the zero value falls outside of the 90% confidence interval (either high or low) then the datasets are not derived from the same population at a 90% confidence interval and the check assays are not consistent.

Based on the drilling location and whether the original assay was fire assay or screen metallic assay, the check assays were divided into six sample sets. For each set and analysis, the mean difference for the check assays (TSL-ALS Chemex) was calculated at a 90% CI and it was found that for each set the zero was within the CI suggesting that the datasets were derived from the same population, or the check assays are consistent.

Q-Q plots are a second method of evaluating the check assays. In this case, the percentiles for each of the data populations are calculated and plotted on a log-log scale. If the datasets are derived from the same population then the percentile values should fluctuate about an equal value line. This evaluation was performed on the Madrid and Doris summer and winter fire assay checks, since they were the only datasets with sufficient data for this analysis.

For each of these plots, the lowest percentile (lowest gold values) all plotted with ALS Chemex data having higher assays then the TSL data. This was partly a detection limit issue because TSL has a lower detection limit (0.03 g Au/t) than ALS Chemex (0.05 g Au/t), however, for the data less than 0.4 g Au/t, ALS Chemex values are higher than TSL. This suggested that TSL may have under reported or ALS Chemex may have over reported the low gold values. This was not a significant problem as these values fell outside of the grade

Watts, Griffis and McOuat

envelopes and were all below any considered “cutoff” grade for the deposits. As of 2006, ALS Chemex is the primary assay lab. Checks are performed by TSL and at the time of writing the 2006 check assays to date are under review. A third lab will be used to resolve any variation in 2006

A more significant problem may be with the Doris 2005 winter fire assay data with values between 1 and 10 g Au/t. These data have TSL values higher than ALS Chemex. This could be an issue with the check samples or may have been due to a lack of data (n=63). As the CIs for the mean differences for the Doris winter program bracketed zero, it is likely that the difference in the Q-Q plot for Doris was a reflection of the lack of data rather than a problem with the check assays.

13.5 SECURITY

Miramar has protocols in place to ensure the security of its core samples and the analytical data derived from them. Among these are:

• Individual plastic sample bags are securely sealed with non-reusable zap straps prior to being placed in larger rice bags for shipment off site in charter aircraft;

• Discovery unloads the sample shipments from the charter aircraft in Yellowknife. If the First Air cargo office is open, Discovery delivers the shipments into First Air’s custody and if not, Discovery holds the shipment in its secure warehouse until First Air is open;

• The shipments are flown to Edmonton using First Air/Air Canada and then are transferred to Canadian Freightways for truck transport to ALS Chemex in North Vancouver;

• Neither drillhole numbers nor meterages are written on the sample tags included with the samples shipped so the laboratory cannot identify the locations of the samples; and

• Assay results are restricted to a small number of Miramar personnel and only a limited number of Miramar personnel can relate the sample numbers and assays to the hole from which they came.

WGM is of the opinion that Miramar’s data and analytical security meets or exceeds industry standards. While WGM has no reason to believe any samples have or might be tampered with, a modest security improvement, at considerable expense, would involve the use of numbered zap straps to secure sample bags and thereby make any overt tampering obvious,

however, someone seriously intent on contaminating samples could simply inject contaminants into bags without opening them, thereby circumventing this precaution.

Data security is maintained in large part by the fact that sample numbers do not directly identify the source of the sample. Only with extreme difficulty could a non-authorized party gain access to the data required to tie assay results to individual holes and meterages.

14. DATA CORROBORATION

WGM Senior Geologist John Sullivan carried out a site visit April 22-25, 2006. The winter diamond drilling program was in full swing, with six diamond drills in operation, during the visit, which was hosted by Darren Lindsay, P.Geo., the Hope Bay Project Manager. During the site visit Mr. Sullivan visited the Doris Deposit area, which is readily accessible via snowmobile from the Windy Lake camp and visited the Madrid Deposit area where drilling was focussed at that time. Given the snow cover it was not possible to take any meaningful surface samples. The Boston deposit is some 55 km by snowmobile from the Windy Lake camp. Given safety concerns, the fact that there was no work taking place at Boston at the time and snow cover prevented making any useful observations, no visit was made there.

In addition, Mr. Sullivan reviewed a selection of current and historic drill core for the Madrid, Doris and Boston deposit areas and took three independent core samples. These were essentially core duplicates of Miramar samples. The samples were chosen to correspond with intervals sampled by Miramar to see how closely they corresponded although that was not their main purpose, which was to determine the general character and tenor of the gold mineralization. He also inspected the core logging and sawing facilities, reviewed core logging and sawing protocols, and QA/QC and security procedures. He held a considerable number of discussions with Mr. Lindsay, who has been involved with the project since 2001 and other Miramar technical staff on site, including the environmental officer.

Following the site visit, Mr. Sullivan visited Miramar’s North Vancouver office, where he held additional discussions with Miramar technical and management staff and gathered information and data required to prepare and complete the report. John Reddick, a WGM Senior Associate Geologist, specializing in Mineral Resource estimation, visited the North Vancouver office from April 24-28, 2006 and held discussions with Miramar technical personnel and the Miramar consultant responsible for the preparation of the Madrid Deposit Mineral Resource estimate. Mr. Michel Dagbert, B.Sc., P.Eng., of Geostat Systems International Inc. (“Geostat”), another Mineral Resource estimate specialist, had numerous communications with the Miramar consultant responsible for the preparation of the Madrid Deposit Mineral Resource estimate, carried out the audit and co-authored this report.

The independent core samples were kept in WGM’s care during and after the site visit and transported to Vancouver as checked baggage. They were then taken to the ACME Analytical Laboratories Ltd. (“ACME”) ISO 9001:2000 accredited laboratory in Vancouver for analysis. They were each assayed for Au (fire assay with a gravimetric finish on 2 Assay Ton (58.3 g) subsamples) and subjected to 30-element Inductively Coupled Plasma-Atomic Emission Spectrometer (“ICP-ES”) analysis (ACME Group 1D procedure on 0.5 g sub-samples).

The sample details and both the WGM and Miramar Au results are shown in Table 9. Correlation between the WGM and Miramar samples was good for the Naartok samples. The WGM sample from Doris ran considerably higher than that of Miramar, likely reflecting the often nuggety nature of the Doris mineralization. The Naartok samples exhibited elevated As, Ni and Sr. The sample population is far too small to draw any conclusions regarding these elevated values.

15. ADJACENT PROPERTIES

In 2003, Strongbow Exploration Inc. carried out a 3,500 m drilling program on the ORO claims north of the Doris Deposit on the northeastern tip of the Hope Bay Greenstone Belt. The objective was to trace the extension of Doris Deposit stratigraphy in search of another deposit. “Interesting stratigraphy” but no gold values were reported. WGM understands that no other mining companies hold mineral properties nor are there any significant gold, base metal or diamond deposits adjacent to or nearby the Hope Bay property.

16. MINERAL RESOURCE AND MINERAL RESERVE ESTIMATION

16.1 GENERAL

WGM’s assignment regarding Mineral Resources consisted of an audit of the December 31, 2005 estimates, as prepared in-house, for the Madrid Deposit Area resource zones, namely Naartok West, Naartok East and Rand, by John Zbeetnoff, B.Sc., P.Geo, Qualified Person, who is not independent of Miramar. WGM is satisfied that Mr. Zbeetnoff is qualified to prepare such estimates, that the estimates have been prepared in an acceptable manner and in compliance with the requirements of NI 43-101 and the CIM Standards. WGM accepts the results as supplied by Miramar.

In WGM’s opinion, the independent audit results and our acceptance and approval of Miramar’s Mineral Resource estimates for the Naartok West, Naartok East and Rand zones fulfil the requirement of NI 43-101.

Miramar has also prepared updated in-house Mineral Resource estimates for the Boston and Doris Deposits and other zones in the Madrid Deposit Area. These estimates have been updated by Miramar periodically since they were last the subject of an independent NI 43-101-compliant technical report, namely one prepared by RPA and dated September 2, 2003. In Miramar’s opinion the changes since the RPA report have not been material. WGM has neither reviewed nor audited the estimates. For the sake of completeness, WGM is reporting them as supplied by Miramar. John Wakeford, P.Geo., Vice President, Exploration for Miramar, is the qualified person under National Instrument 43-101 for Miramar, and he has assumed responsibility for the Mineral Resource estimates (including the Probable Mineral Reserve referred to in the final paragraph of this Section 16.1), including those neither reviewed nor audited by WGM, as set out below in Tables 10 and 11.

Tables 10 and 11 present the December 31, 2005 Indicated and Inferred Mineral Resource estimates.

In addition to Indicated and Inferred Mineral Resources, Miramar reports a Probable Mineral Reserve of 458,200 t grading 22 g Au/t for the Doris Hinge Zone. This Probable Mineral Reserve was estimated during the course of a Feasibility Study carried out by Steffen Robertson and Kirsten (Canada) Inc. (“SRK”) on the Doris North Project in 2002. A summary of the Feasibility Study supporting the Probable Mineral Resource was presented in an independent technical report dated February 2003 and filed on SEDAR February 10, 2003. This Probable Mineral Reserve is included within the Indicated Mineral Resource reported in Table 10, to which dilution of 39% and a mining recovery factor of 95% have been applied. The price of gold used in the Feasibility Study was US$325/ounce. A brief summary of the Feasibility Study results is presented in Section 19.1.2.

16.2 REVIEW OF THE IN-HOUSE MINERAL RESOURCE MODEL FOR NAARTOK-RAND-SPUR IN THE MADRID AREA

As indicated previously, the Madrid area of the Hope Bay Project is divided in several sectors, each sector being split in several different mineralized zones. Mineral Resources of the mineralized zones of the Naartok, Rand and Spur sectors (NRS hereafter, with 46 mineralized zones all together) have been re-estimated in the early months of 2006 with results from the last drilling of 2005 on those sectors. This section describes the data, as well as the methodology used, to re-estimate those Mineral Resources.

16.2.1 DRILLHOLE DATA

Mineral Resource modelling and estimation of NRS uses data from 410 holes drilled between years 1994 to year 2005 in the Madrid area. Collar coordinates are within a region from 432,568E/ 7,549,675N/ 21Z to 434,712E/ 7,551,528N/ 76Z, i.e., about 2.15 km (EW) by 1.85 km (NS) by 55 m (Z). The total length of the holes is 110,989 m. Individual lengths vary from 10 to 830 m, with an average of 271 m. Holes are drilled in all directions (Figure 18), but more specifically to the N65°, N180°, N240° and N270°. Dip angles at the collar vary from -44° to -90° (only 3 vertical holes), with an average of - -56°. Holes have been thoroughly surveyed with deviation measurements (both azimuth and dip) approximately every 3 m.

There are up to 37,711 assay intervals in 395 of the 410 holes, totalling 41,195 m. Interval lengths range from 0.1 m to 10 m, with an average of 1.09 m. Gold values range from less than 0.03 g/t to 586.4 g/t. About half the intervals (14,268) have no (zero or less than

- 83 -

detection limit) grade. Assay intervals in the interpreted zones of NRS have been tagged with a zone code (Figure 18). There are 9,976 intervals within the zones with an average length of 0.99 m, and an overall average uncut grade of 2.71 g/t.

16.2.2 GEOLOGICAL MODEL

Limits of the 46 mineralized zones of NRS are interpreted as 3-D solids. Some of the solids overlap (e.g., the solid of the so-called high grade Z-Shoot is totally included within the solid of the Z zone and solids of small veins Q1 and 4C are cutting through solids of other zones in Naartok West, Figure 19) but a sound priority order ensures that mineralized volumes are only accounted for once. Near the top of the deposit, a solid of overburden properly erodes the solids of the mineralized zones. Small solids of barren dike or diabase also cut through some of those mineralized solids (see Figure 19).

Densities (specific gravities) used to convert volumes into tonnages vary between 2.85 and 2.90 t/m³, which is a rather narrow range. They are supported by about 400 sample data (Table 12).

The total tonnage of potentially mineralized material in NRS is 69.2 Mt. Table 12 shows that 60% of that material is concentrated in six zones: A1_N of Naartok East with a low dip to the NW (11.4 Mt), Z of Naartok West with a high dip to the N (9.2 Mt), YE of Naartok West with a low dip to the NW (5.9 Mt), Y of Naartok West with a high dip to the N (5.2 Mt), YE_N of Naartok West with a low dip to the NW (5.0 Mt) and A1 of Naartok East with a low dip to the NW (4.8 Mt).

16.2.3 INTERCEPTS OF MINERALIZED ZONES WITH DRILLHOLES

The 46 mineralized zones of NRS are intersected by 267 of the 410 Madrid drillholes. Table 13 gives the average length along the hole and uncut grade of the corresponding 634 intercepts (most drillholes intersect more than one zone and in some cases, there are several different intercepts of the same zone in the same hole). All together, the average intercept length is 16 m and the average uncut grade is 2.7 g/t.

Intercept lengths, when combined with drillhole and average zone orientation, allow the verification of the consistency of solid volumes (hence overall tonnage of potentially mineralized material) with what is actually intersected by the drillhole. For each zone, a longitudinal projection plane can be selected, which is vertical for zones dipping at more than 45° and horizontal otherwise. Projection of the zone solid on the projection plane gives a contour of maximum extension of the zone in the projection plane and the area within that contour. The length of the intercept of any given drillhole within the zone is converted into a zone thickness perpendicular to the projection plane (that computation takes into account the azimuth and dip angle of the drillhole at the intercept and the average dip and strike of zones listed in Table 12). For some holes with two intercepts with the same zone, a single projected intercept with a thickness equal to the sum of the thicknesses of each piece replaces the two intercepts. On the projection plane, each projected intercept is given a polygon of influence within the contour of maximum extension, hence an extension volume which is the product of the polygon area by the thickness of the intercept (Figure 20). An estimate of the mineralized volume for the zone is the sum of those extension volumes for all projected intercepts in the same zone.

For the audit, this exercise has been completed for the most important zones. In all cases, that independent estimate of the mineralized volume is close to the volume of the actual solids, notwithstanding overlaps: 3,453 km³ vs. 3,689 km³ for Zone Z, 423 km³ vs. 323 km³ for Z-Shoot, 1,691 km³ vs. 1,853 m³ for Zone Y, 4,166 km³ vs. 4,031 km³ for Zone A1_N and 2,045 km³ vs. 2,088 km³ for Zone YE. For those five zones, the total mineralized volume derived from the actual 3-D solids is just 1.7% more (11,984 vs. 11,778 km³) than the polygonal estimate from intercept lengths and maximum extension on a projection plane.

As illustrated by Figure 20, the polygonal maps of the zones on projection planes give some good insight on the density of control information for various parts of the zone and they can be used as a guide for the classification of zone Mineral Resources.

16.2.4 GOLD ASSAYS WITHIN INTERCEPTS AND CAPPING

Table 13 (shown previously) gives the statistics of gold assays for individual intervals within each zone. All together, there are 9,995 intervals of about 1 m within the 634 intercepts of 267 holes with the 46 zones.

Table 13 also lists the cap limits applied to original assay data in each zone. Applying that capping scheme, 29 intervals out of about 10,000 are capped and 6.2% of the gold metal is lost in the process. After capping, the average gold grade of all samples in the zones decreases from approximately 2.7 g/t to 2.5 g/t.

As illustrated by Figure 21, selected cap limits generally correspond to sudden slope increases of the high end of the cumulative frequency curve with a log scale. Unfortunately, those inflexion points are not unique and it is possible to propose a more severe capping scheme whereby 72 original gold assays are capped (about 0.7% of total) and the gold loss increases to 9.1%, i.e., 3% more than gold loss in the first scheme.

16.2.5 COMPOSITING AND VARIOGRAMS OF COMPOSITES

Prior to block grade interpolation, cut assay interval gold values within zone intercepts are numerically composited into fixed length (and longer) intervals so that composites can be considered as control points for grade with the same support, therefore sample length does not have to be taken into account in the block interpolation. The selected composite size is 2.5 m with an actual range from 0.5 to 3.5 m.

Overall the 9,995 assay intervals within the 634 drillhole zone intercepts are converted into 4,203 composites with the same average cut grade of 2.5 g Au/t. As expected, variability is high in all zones with coefficients of variation anywhere between 100% and 200% in the most important ones (see Table 14). Overall, that coefficient of variation is 172%.

- 91 -

Watts, Griffis and McOuat

Cap limits are preferentially taken in places where we see a sudden slope increase of the high end of the cumulative frequency curve with a log scale. In the Z zone case, 72 g/t is indeed such a point, but we could also pick 30 g/t, which is the next point. In the Y Zone case, the selected limit of 55 g/t is an inflexion point, but we could also pick 35 g/t, which is the next point down the curve.

Some attempts at characterizing the spatial continuity of the gold grade of composites by 3-D variograms have been made. Rather than having specific variograms in each zone (some of the smaller zones do not have enough composites to compute meaningful variograms), zones have been grouped according to average orientation (Table 12) into at least five sets:

• Set 1: Zones Z, Z-FW, Z-HW and Z-Shoot: average plane dipping 65° to N – 730 composites;

• Set 2: Zones Y, Y-HW, Y-HW2, X-1, X-2, X-3 and X-4: average plane dipping 55° to N – 999 composites;

• Set 3: Zones A1, A1_N, A1_S, A1_SE, A1_SW, A2, A2_S, A2_SW, B1, B2 and B3: average plane dipping 35° to N315° – 1186 composites;

• Set 4: Zones YE, YE_N, YE_FW, YE_HW and YEN_FW: average plane dipping 35° to N315° – 537 composites; and

• Set 5: Zones RZ, RZ_FW, RZ_HW, R1A, R1A_FW, R1A_HW, R1B, R1B_HW, R2 and PGP: average plane dipping 80° to N15° – 564 composites.

The remaining composites (the two crossing veins, i.e., Q1 and Vein 4C + T2, TX, TX_HW, AC, AR, CC and CR) are not plentiful enough for meaningful 3-D variogram computation.

For each set, variograms were computed along five directions plus the average variogram in all directions:

• the four principal directions of the average plane, i.e., horizontal strike + dip + the two intermediate directions called plunge east and plunge west). Lag distance is 30 m and tolerance is ±20°; and

• the direction perpendicular to the average plane (called “Across”), which is not far from the direction of drillholes crossing the zone. Lag distance is 2.5 m and angular tolerance is ±30°.

Variograms are actually 1-correlogram, i.e., the sill is 1 (corresponds to a correlation coefficient of 0).

In each set, there are no pairs made of a composite in one zone and another composite in another zone.

Experimental variograms and tentative models are shown on Figure 22. In all cases, the average variogram (which fits the “across” variogram for very short distances) indicates a moderate relative nugget effect of about 30%. Range across the zones appears shorter and are in the order of 10 m in all sets, except the third one where variograms look very isotropic. In the average plane of the zone, there is no obvious anisotropy (in other words, strike=dip) and ranges do not seem to exceed 40 m.

16.2.6 BLOCK GRADE INTERPOLATION

Cut grade of 2.5 m composites are distributed among blocks or portion of blocks on a 3-D grid and filling mineralized solids. The average grade of each block is interpolated from cut grades of available composites around the block, within a search ellipsoid of given size and orientation.

Selected blocks are 5 m cubes to account for the different orientations of zones, the generally complex geometry of mineralized solids and the minimum spacing between intercepts, which is of the order of 25 m. The block matrix has a maximum of 350 columns (along EW) from 432650E to 434400E, 280 rows (along NS) from 7550000N to 7551400N and 180 benches (along vertical) from Z=-780 to Z=+120. This is large enough to cover the maximum extent of the mineralized solids (from 432815E to 434220E, 7550185N to 7551200N and –665Z to +55Z).

As a general rule, blocks or portion of blocks in any given mineralized zone are interpolated only from composites in the same zone. The only exceptions are zones Z and RZ, where blocks are interpolated from composites in both zones together, the justification being that RZ zone is the continuation of the Z zone in the Rand sector.

For the Madrid Mineral Resource estimate, the search for composites around a block uses ellipsoids of increasing size, together with a minimum number of composites within an ellipsoid and a maximum number of composites in the same hole. The more stringent search starts with a 150 x 75 x 50 m ellipsoid and a minimum of 9 composites within the ellipsoid, together with a maximum of 3 composites in the same hole (which guarantees that interpolation is done from data from at least 3 intercepts). If those conditions are not met, the second attempt to interpolate the block uses the same ellipsoid, but the minimum number of composites is reduced to 4 (hence, now blocks may be interpolated from data from just two different intercepts). The next step relaxes the search conditions further by increasing the size of the search ellipsoid by about 30% (and slightly reducing its anisotropy) to 200 x 100 x 75 m, while keeping the minimum number of composites at 4, but sometimes reducing the maximum number of composites in the same hole to 2 (still allowing interpolation from data from only two different intercepts). A fourth step is also possible with a 250 x 170 x 110 m ellipsoid, but this step seems to be rarely used. In all cases, interpolation is done with the closest (with anisotropic distances) 18 composites within the search ellipsoid. No octant search is implemented.

Great care has been taken to adapt the orientation of the search ellipsoids to the local changes in the orientation of the mineralized zones, which is definitely good practice in order to avoid artefacts in the pattern of grade variation within zones (elongation of high and low grade shoots oblique with respect to zone limits), especially when anisotropic distances are used. Table 15 details the 28 “orientation” sectors defined in the mineralized zones Z and Z-Shoot. In this case, those sectors correspond to rectangular panels on the EW vertical long section. Orientation of ellipsoids is defined according to Gemcom’s 3 rotation angles (along Z, rotated Y and finally rotated Z). The first two angles can be considered as first approximations to the 90°-azimuth and dip of the long axis (e.g., 90/72 = dip 72° to N). They define the plane of the long + intermediate axis which fits the average plane of the zone (e.g., 90/72 means that this average plane strikes EW and dips 72° to N). The third angle gives the final plunge of the long axis in the average strike + dip plane (e.g., –15 means that azimuth of the long axis is more like N15° than N0°). According to the numbers in Table 15, the strike of Z and Z-Shoot varies from NW-SE (Z = 48) to NE-SW (Z = 135), while the dip varies from 45° to 82° to the N. The third angle is always 15°. In all cases, the long axis is near the dip of zone, while the intermediate axis is near the strike.

Z, Y and Z are the angles of the 3 successive rotations to set the search ellipsoid (according to Gemcom’s convention). Max, Int and Min are the 3 principal radii of that search ellipsoid. Maxsh is the maximum number of composites from the same hole. Xmin/Xmax, Ymin/Ymax and Zmin/Zmax are the limit column, row and bench indices for the interpolated panel. Mins and Maxs are the minimum and maximum number of composites in the search ellipsoid, #blk is the number of blocks in the panel interpolated in the run and g Au/t is the average interpolated value.

Watts, Griffis and McOuat

Once composites have been selected, interpolation of the grade of the block from the composite grades is by inverse squared distance (“ID²”). In that weighting, distances are recomputed using the radii and orientation of the ellipsoid (= anisotropic distances). In other words, for a 150 x 75 x 50 m ellipsoid, a composite at a distance of 30 m from the block in the direction of the long radius (150 m) has the same weight as another composite at a distance of 15 m along the direction of the intermediate radius (75 m) or another one at a distance of 10 m along the direction of the short axis (50 m).

Views of the Z and Z-Shoot blocks are shown on Figure 23. Visually speaking, there is always a good agreement between block values and that of nearby composites. The orientation and anisotropy of most ellipsoids used to interpolate the blocks of Z and Z-Shoot show well on the long section with elongated shoots of high and low grade along a high plunge to the east (which is the main axis of the Z-Shoot zone itself).

Statistics of final block interpolated values are summarized on Table 14. All together, 321,943 blocks or block fractions have been interpolated. In a majority of cases, the mean interpolated grade in a zone is less than the mean composite grade, which corresponds to the usual situation of less data in not densely drilled areas. Overall, the mean interpolated block grade (2.25 g Au/t) is 10% less than the mean composite grade (2.50 g Au/t).

16.2.7 MINERAL RESOURCE CATEGORIZATION

Individual blocks or block fractions in any given mineralized zone are classified as either an Indicated or Inferred Mineral Resource. A block is classified as Indicated if there are sufficient composites of the same zone (or both zones, in the Z and RZ case) in order for the interpolation to be completed. The criterion used is a minimum of 5 composites from at least 3 different intercepts (maximum of two composites in the same hole) within a search ellipsoid of 66 x 45 x 30 m (hence smaller and less anisotropic than the standard search ellipsoid used for grade interpolation). The orientation of that search ellipsoid is the same as that for grade interpolation, i.e., it is defined by panels based on local changes of the orientation of the zones themselves (i.e., 28 panels for Z and Z-Shoot and 135 panels for all zones together). Miramar’s justification for this criterion is that it matches the traditional rule used by the company for the other Hope Bay deposits, i.e., an Indicated Resource is material recognized by holes drilled on a 50 m x 50 m grid.

Table 14 (last column) gives the percentage (by volume or tonnage) of blocks or block fractions classified as Indicated in each zone based on the above criterion. That percentage varies from 0% (by definition, all small zones with less than 3 intercepts but also zones with more intercepts like the Q1 and Vein_4C veins) to 100% (Zone X_2) with an overall average of only 38%. In other words, tonnage wise, about 2/3 of the estimated Naartok-Rand-Spur Mineral Resources are in the Inferred category. As expected, the Indicated fraction has a better average grade than the Inferred fraction (2.67 g/t vs. 1.99 g/t), but more than 50% of total estimated ounces are categorized as an Inferred Mineral Resource.

Figure 24 shows the categorization of Mineral Resource blocks of the Z and Z-Shoot zones by Miramar. It compares that categorization to a simpler one based on average intercept grid on the long section. In that latter case, Inferred Mineral Resources are predominantly from marginal zones, especially at depth, with no data or a much longer spacing (in this case 100 m or more) between intercepts. In those two zones, it appears that the Miramar`s classification is more conservative than our suggested categorization based on a visual delineation of sectors with about the same intercept spacing on the long section. This tendency is confirmed in other zones and it explains the high percentage of Inferred Mineral Resources in Miramar`s classification.

16.2.8 RESULTS

Indicated and Inferred Mineral Resources are summarized in Tables 16 and 17, respectively, at no cutoff and at cutoffs of 1, 2 3 and 4 g Au/t directly applied to block or block fraction grade estimates in each mineralized zone.

It is important to stress that Mineral Resources above a selected cutoff is not indicative of the average production grade, if such a cutoff is applied in a future mining operation. In that case, Mineral Reserves would have to be determined with the appropriate mining dilution and losses properly added to the Mineral Resources. Presently, there are no Mineral Reserves defined in the NRS sectors of Madrid. Mineral Resources above cutoff (especially with an ID² interpolation) are just indicative of the in-situ grade distribution of fairly small blocks (much smaller than mining blocks) in the different zones.

Top right: projected intercepts (Z zone only) with extension polygons of 30 m radius. Those polygons help define the limit of an upper central sector with about a 40 m grid of intercepts across the zone, which would be an acceptable sector of Indicated Mineral Resources. Bottom left: projection of blocks classified as Indicated by Miramar. All are within the alternative limits. Bottom right: projection of blocks classified as Inferred by Miramar. They cover the entire alternative Inferred sector, plus a significant part of the alternative Indicated sector.

Notwithstanding the previous remark, the numbers in Tables 16 and 17 show that:

• at the low cutoff of 1 g Au/t, for the Indicated Mineral Resources, 63% of the gold metal (2.19 Moz) is contained within just six zones: YE (420 Koz), Z (390 Koz), A1 (340 Koz), Y and Z-Shoot (230 Koz each) and A1_N (190 Koz);

• at the high cutoff of 3 g Au/t, the same six zones with the highest contained gold has their contribution increased to 88% of the total (1.30 Moz); and

• Inferred Mineral Resources are more evenly distributed among the zones. At the 1 g Au/t cutoff, only 48% of the total metal (2.51 Moz) is contained within five zones (three being the same as in the Indicated category), distributed as follows: A1_N (400 Koz), Z (360 Koz), YE (320 Koz), and two new zones: YE_NFW (170 Koz) and RZ_FW (150 Koz). At the higher 3 g Au/t cutoff, zones YE and Z have the most contained gold at 220 Koz and 210 Koz, respectively.

16.2.9 SENSITIVITY ANALYSIS

The estimated quantity of metal in a Mineral Resource is sensitive to the cap limits applied to high assay values in each zone. As indicated in Section 16.2.4, it is possible to implement a more severe capping approach, which would tend to maintain a 10:1 ratio between cap limit and average uncapped grade in all zones. If the blocks are re-interpolated from the new set of capped composites, about 3.4% of the Indicated gold and 2.7% of the Inferred gold at no cutoff (Table 18) would be lost. At the 2% cutoff, differences are a little bit more pronounced, as 4.6% of the estimated gold metal is lost in both categories. Nevertheless, those percentages are within the uncertainty of Mineral Resource estimates and the possible gold loss in Indicated resources is largely offset by the conservative resource classification adopted by Miramar.

Estimated Mineral Resources above a cutoff are sensitive to the selected block grade interpolation and the degree of smoothing involved in each method. If the blocks are re-interpolated by ordinary kriging (“OK”) with a variogram model similar to those shown in Section 16.2.5 (i.e., a 30% relative nugget effect, a 40 m range in the average plane of zone and a 10 m range perpendicular to that plane), the additional smoothing of kriging with such a variogram generates more tonnes at a lower grade at low cutoffs, such as 1 g/t and 2 g/t and

less tonnes at a lower grade at higher cutoffs, suck as 3 g/t and 4 g/t (see Table 18). At the 2 g Au/t cutoff, kriging generates about 5% more tonnes, but about 6.5% less grade, hence an overall loss of ounces of about 2% occurs. Those differences are within acceptable limits.

Sensitivities were run on the Mineral Resources of 23 zones (out of a total of 46), which represent 91% of the Indicated ounces and 81% of the Inferred ounces at no cutoff in the base case (in yellow) . Cut: Orig. = base case scheme described in Table 13. Alt. = alternative and more severe scheme which caps about 0.7% of mineralized intervals and 9.1% of their expressed gold metal. Interp.: ID²=inverse squared distance (base case); OK=ordinary kriging.

At higher cutoffs (3 g/t and more), more differences are observed between the base case (soft capping + ID²) and alternative models with either a more severe capping or a more smoothing block grade interpolation method like OK. For those reasons, we do not recommend that the base case model be used to quote Mineral Resources at higher cutoff grades.

17. MINING ACTIVITIES

Previous owner BHP conducted an underground exploration and bulk sampling program on the Boston deposit between 1996 and 1997. The work was carried out by Procon Mining and Tunnelling Ltd. (“Procon”) of Burnaby B.C. The deposit was accessed via a portal and decline. Some 2,340 m of decline/ramp/drifting/crosscuts were excavated to 200 m vertical and 201 m of raise development was done. Drifting was done on the B2 and B3 Zones.

Approximately 27,000 tonnes of B2 and B3 mineralized material and 105,000 tonnes of waste were brought to surface and almost all of it was crushed to 1.5 to 2.0 cm size. The waste was used for local fill and the airstrip. A sampling tower was set up to collect representative samples of “ore” (~1:1,000 sample reduction). The samples from the tower were collected on a round by round basis. In 1996, 9.4 tonnes of this material and sent to the BHP Reno Lab and in 1997 an additional 11.7 tonnes were sent to Lakefield Laboratories (now SGS Lakefield) for detailed analysis of grade, recovery and metallurgical characteristics as described in Section 18.

Miramar has carried out no mining activities on the property, however, did dewater and rehabilitate the Boston decline/ramp in 2000, after which it carried out a detailed underground diamond drilling program. The dewatering/rehabilitation work was carried out by Procon and the drilling was conducted by Advanced Drilling Ltd. of Surrey, B.C. Miramar has used some of the remaining BHP underground material for local fill.

18.1.1 1992 BOSTON DEPOSIT

BHP carried out polished section and mineralogical studies and collected 726 drill core pulps from which it prepared four composite samples for in-house metallurgical studies. One sample was composed of quartz dolomite vein material with 3-15% pyrite at or near the contact between altered mafic volcanics and graphitic sediments. The head assay was 33.2 g Au/t. Two samples were composed of quartz dolomite vein material with slightly lesser pyrite in mafic volcanics. The head assays were 6.24 and 11.6 g Au/t. The fourth was composed of lesser quartz carbonate veining, 5-20% pyrite in graphitic sediments. The head assay was 5.27 g Au/t.

Both flotation and direct cyanidation testwork was carried out and concluded that all samples were amenable to both processes and satisfactory recoveries up to 95% were obtained. It was further concluded that direct cyanidation could recover 85-95% of the gold in 48 hours of leach time, although the high graphite composite returned only 82% recovery. Lime and cyanide consumption were moderate and finer feed sizes improved recoveries although no significant grinding testwork was carried out. It was concluded that flotation could recover 95% of the gold in angle rougher stage. Again, finer feed sizes improved recoveries. Cyanidation of the flotation tails was effective and increased overall recoveries to 99%.

Further cyanidation and flotation testwork was recommended, as was consideration of a gravity preconcentration circuit.

18.1.2 1996-1997 BOSTON BULK SAMPLING PROGRAM

Approximately 9.4 tonnes of bulk sample material from the 1996 program was sent to BHP’s in-house lab in Reno. BHP carried out grindability, gravity, flotation and cyanidation testwork on several individual and composite samples. The studies noted the presence of potentially preg robbing carbon in several samples but that Boston “ore” would be free milling and have recoveries of 92-95.5%. Two possible process flow-sheets were envisaged:

Watts, Griffis and McOuat

gravity and flotation circuits with a secondary cyanide leach on the tails, or the simpler whole-ore cyanide leach. BHP concluded that whole-ore leach was the preferable route given somewhat better recoveries.

Lakefield Research Limited received 10.7 tonnes of bulk sample material from the 1997 program and carried out testwork basically similar to that of BHP’s lab, namely gravity, flotation and cyanide leach testwork on three composites. The composites were designated B2 Average, B2 Low and B3.

Results for B2 Average showed that gold recoveries of 89% were achieved by a combination of gravity preconcentration followed by flotation and cyanidation of concentrate versus 94% gold recovery by a combination of gravity and leaching the gravity tailings. Lakefield seemed to favour a flotation concentrate leach processing option since a smaller plant would be required.

18.2 MIRAMAR STUDIES

18.2.1 GENERAL

Miramar has carried out a variety of metallurgical testwork on drill core from several of the Hope Bay deposits. This work has in small part been a follow-up of BHP work on Boston but has focussed largely on the Doris/Naartok/Madrid Trend deposits and zones.

As drilling has progressed and success been achieved on different areas of the property, a variety of development options have been reviewed by Miramar and this has led to several metallurgical testwork programs, some of which were curtailed prior to completion. WGM has provided brief summaries of certain of these programs below.

18.2.2 2001

Concurrent with the Preliminary Assessment discussed in Section 19.1 below, a series of metallurgical tests was carried out by Process Research Associates Limited (“PRA”) of Richmond, B.C., on drill core samples selected from the Doris, Naartok and Suluk deposits.

- 109 -

Watts, Griffis and McOuat

Doris North

Samples were obtained from three areas:

• Doris central — Stringer Zone (CSZ);

• Doris central – Lakeshore Vein (CLV); and

• Doris North.

The use of gravity recovery followed by cyanidation of gravity tailing or cyanidation of flotation concentrate provided for a promising treatment procedure:

• The gravity concentrate typically recovered 25% to 50% of the gold present depending on the composite sample tested and grind conditions used;

• The primary grind can be relatively coarse (80% passing 149 microns) and will impact the size of the mill as well as the power required. Gold recovery improved at finer grind sizes and this may be justified pending economic evaluation;

• Overall gold recoveries using gravity and cyanidation ranged from 89% to 98.5% depending on the composite sample tested and conditions used;

• The gold recovery to the flotation rougher concentrate is good and only this concentrate needs to be reground prior to cyanidation, rather than the whole ore; and

• The overall recovery of the gold by gravity and cyanidation of reground flotation concentrate ranged from 93% to 98%.

Suluk

The recognition of interbanded graphite (carbon) in the Suluk mineralization led to a series of metallurgical tests designed to examine the preg robbing characteristics of the graphite. Nine composites were prepared using core from seven drillholes.

Results of direct cyanidation, over 48 hours, for the nine composites showed that in general, with increasing graphite content there is a corresponding decline in gold recoveries Composites with only trace graphite had >85% recoveries and composites with more than 5% graphite had recoveries <29%. Gold losses may be attributed to a variety of factors, including preg robbing characteristics (natural organic carbon adsorbing dissolved gold) and the presence of refractory gold (finely disseminated gold locked within the sulphide matrix).

Overall, the test work showed that it is possible to create a high-grade gravity/flotation concentrate, which contains between 80% and 85% of the gold available. Higher recoveries

- 110 -

Watts, Griffis and McOuat

are achievable but weight pulls are too large for consideration of potential offsite processing. The program data suggested a grind size of ~149 microns, with a rougher flotation time of 25 minutes, and using 55 g/t PAX are sufficient for optimum gold recovery from material in the heart of Suluk as it was known in 2001. Flotation seems to get approximately 93% of gold into concentrate even at a coarse grind.

Naartok

Samples were collected for Naartok (Lens A and Lens B) and tested at 3 different primary grind sizes of 80% passing 140 microns, 74 microns and 44 microns respectively. The combination of gravity concentration and cyanidation achieved excellent overall Au recovery of 89% to 97% at the finest primary grind size.

Boston

A Boston composite sample with an Au grade of 14.5 g/t was also tested at three different grind sizes. The Au recovery varied between 93.9% at the coarse grind to 97.7% at the finest grind size.

18.2.3 2003 BOSTON/NAARTOK PROCESSING PLANT STUDY

A.K. Winckers & Associates, Mineral Processing Consulting of North Vancouver, reviewed all previous metallurgical testwork in the course of designing/costing a grinding and processing plant as part of a Preliminary Assessment being carried out by SRK Consulting of Vancouver. This project focussed on developing a 2,700 tonne per day plant to process Boston and Naartok “ores.” This was a project separate from the Doris “studies” referred to in Section 19.1 below and was apparently not pursued to any degree.

18.2.4 2004/2005 NAARTOK STUDY

PRA carried out baseline cyanidation and flowsheet studies for the Naartok deposit as known at that time.

18.2.5 2005 DORIS NORTH STUDY

PRA carried out a metallurgical testing program on one pulp reject composite, prepared from 18 individual drill core samples, from Doris North. The composite responded well to the

- 111 -

Watts, Griffis and McOuat

circuit developed for Naartok samples in a previous test program. Direct cyanidation, at a grind size of 80% passing 74 microns, pulp density of 40% solids with 1 g/l NaCN concentration at pH 11, achieved a 95.4% extraction in 24 hours and over 99% Au recovery in 72 hours of retention. The assay results showed that the composite contains on the order of 0.65% S^2- and 20 g Au/t, partially in the form of coarse gold. The sample had a specific gravity (“SG”) of 2.68 and gravity separation recovered 47% of the gold into a pan concentrate grading 8,635 g Au/t. An overall recovery of 97% Au was achieved using a combination of gravity + flotation and cyanidation processing, with over 90%. Modified Acid Base Accounting (“ABA”) testing indicated that the composite is not a potential acid producer. All metals in the Special Waste Extraction Procedure (“SWEP”) leachate were below the Standard Regulatory (B.C.) Guidelines of Concern.

18.2.6 2005/2006 NAARTOK STUDY

Three composites were prepared from 114 individual drill core samples from 2005 drillholes. These were stage ground and subjected to some grindability and work index testing in addition to metallurgical testwork.

Samples were near surface and higher in organic carbon, sulphide and arsenic than previously tested material. The objective was to adapt a previously developed flowsheet to achieve higher gold recovery at coarser primary grinds with better rejection of the gangue by using a combined gravity + flotation and cyanidation process. Here, the precious metal would be concentrated by a single-pass gravity with cleaning by hand panning, with or without a concentrate-upgrading step on pan tails by flotation. Three or four stages of rougher flotation were to be used to recover additional gold from the gravity tails, and regrinding of the various concentrates would be tested prior to cyanidation.

The samples were found to be amenable to the gravity + flotation and cyanidation process developed previously. The simple flowsheet appears to be robust and capable of handling feed at relatively coarse primary grinds of up to 200 microns. The gold and sulphide were effectively concentrated in well characterized products and found to leach well in dilute NaCN at relatively fine regrind sizes. Overall process extractions over the 88% Au level were indicated, for several material types tested and at various head grades. Further optimization, primarily of the gravity and flotation circuit, on a larger scale, was recommended.

19. OTHER RELEVANT DATA AND INFORMATION

19.1 DORIS NORTH DEPOSIT ECONOMIC STUDIES

19.1.1 HBJV PRELIMINARY ASSESSMENT

In 2001, the HBJV commissioned a Preliminary Assessment (also referred to as a Scoping Study) on the high-grade Doris Hinge Zone, now known as the Doris North deposit. Independent consultants SRK (with a large contribution by Bateman Engineering (“Bateman”)), in conjunction with Nuna Logistics and Miramar, prepared various portions of and completed the Scoping Study, which was prepared according to and in compliance with NI 43-101 standards. Miramar work was reviewed by SRK in terms of NI 43-101 compliance. The mining scenario involved a small open pit followed by ramp access and underground mining of the deposit. Tonnage mined included 75% Indicated and 25% Inferred Mineral Resources. Grades were uncapped. Principal base case parameters and conclusions were as follows:

Gold Price	US $280
Exchange Rate	1.57
Total Ore Milled	471,600 t
Daily Throughput	600 t
Diluted Grade	18.5 g Au/t
Metallurgical Recovery	97%
Total Gold Recovered (2.1 years)	271,724 oz
Cash Cost	US$114/oz
Total Cost	US$177/oz
CAPEX	C$26.685M
Net Pre-tax Cash Flow	C$44.786M
NPV @ 5% Discount Rate	C$37,215M (incl. a 1.8% NSR payable to NTI)
Pre-tax ROR	85.2%
Payback Period	13 months

The Scoping Study pointed to a robust project. The results were detailed in a technical report filed on SEDAR March 7, 2002.

- 113 -

Watts, Griffis and McOuat

The Scoping Study was partially updated by Miramar following infill drilling during 2002 as part of the preparation of a Feasibility Study described below. Tonnage was virtually identical but all Indicated Mineral Resource grades were capped and cutoff grades were applied as were minimum mining widths. Overall the grade increased by 19% to 22.0 g Au/t and recovered ounces by 18% to 323,900.

19.1.2 FEASIBILITY STUDY

In 2002, Miramar commissioned a Feasibility Study on the Doris North deposit. SRK managed the study and Bateman acted as the lead consultant. Nuna Logistics, and Miramar personnel again participated. In early 2003, Miramar announced that its Board had received and accepted the Feasibility Study. Principal base case parameters and conclusions were as follows:

Gold Price	US$325
Exchange Rate	1.575
Total Ore Milled	467,157 t *
Daily Throughput	668 t
Diluted Grade	21.9 g Au/t
Metallurgical Recovery	94.9%
Total Gold Recovered (2.1 years)	311,693 oz
Cash Cost	US$109/oz
Total Cost	US$190/oz
CAPEX	C$39.3M
Net Pre-tax Cash Flow	C$69.3M (incl. a 1.8% NSR payable to NTI)
Pre-tax ROR	136%
Payback Period	6.6 months

* Total made up of the 458,200 t Probable Mineral Reserve at Doris Hinge plus 9,000 t of mineralized underground material stockpiled at Boston.

The Feasibility Study also pointed to a robust project. The results were detailed in a technical report filed on SEDAR on February 10, 2003.

Portions of the Feasibility Study and certain of its parameters and conclusions have been revisited by Miramar since its completion, in particular with regard to the recent and general

- 114 -

Watts, Griffis and McOuat

rapid increase in the cost of energy generation, plant equipment and construction materials. Miramar feels that these increases have been more than offset by the increase in the price of gold since 2003.

19.2 ENVIRONMENTAL MATTERS

19.2.1 GENERAL

Miramar has comprehensive, industry standard environmental policies and practices. There is a Miramar environmental officer assigned to the project, whose workplace is the project site. He has adopted a proactive, preventative approach to the challenges of the project and has developed a strong, open and positive working relationship with Nunavut environmental authorities with the Kitikmeot Inuit Association (“KIA”). Drill site and other reclamation activities are carried out on an ongoing basis.

Reportable spills are those over 25 l, including fuel, sewage, salt and grey water. During 2005 there were two reportable fuel spills, both at the Windy Lake camp. Remediation had been undertaken and it is hoped the spills will be “closed off” before the end of 2006.

There was a 19,000 l fuel spill at the Windy Lake camp during 2004. On May 26, 2006, Miramar, MHBL and Miramar subsidiary Miramar Con Mine Ltd. were each charged in relation to the spill. Miramar does not anticipate that the charges will materially adversely affect Miramar’s financial condition or results of operations, or its ability to develop the Hope Bay Project.

There were two reportable spills at Boston in 2003. It is planned to apply for close off during 2006.

In general, remediation involves treating contaminated water and soil and leaving it on site, however, depending on circumstances it may be required to take such material off site for permanent disposal.

EBA Engineering is carrying out certain of the monitoring and soil and water testing activities related to of the outstanding incidents.

- 115 -

Watts, Griffis and McOuat

Miramar monitors the “ore” piles stored on a pad adjacent to the portal at the Boston deposit. Of the approximately 27,000 t of “ore” brought to surface by BHP, approximately 21 t were shipped off site for testwork, an unknown small amount has been used by Miramar for airstrip levelling and other local uses and there are approximately 9,000 t grading 8-9 g Au/t remaining in the piles. Water sampling indicates that there is no acid drainage from the piles or the crushed rock pad and that they pose no environmental hazard. There is no settling pond at the Boston site.

19.2.2 ENVIRONMENTAL AND LAND USE LICENCES

Miramar holds two water licences issued by the Nunavut Territorial Government. These are for water use and waste disposal sites for the Boston and Windy Lake camps, require that certain tests be carried out on a regular basis and they must be renewed on an annual basis. Starting in 2006, there are certain measurable usage amounts prescribed with the licence fees based to some extent on actual usage. Regardless, the cost for these licences is small.

There are two Nunavut Land Use Licences; one licence is for underground and exploration work in and around the Boston deposit site and another is for all other exploration work and the camps in the Hope Bay project area. These licences must also be renewed annually and the cost is nominal.

19.2.3 DORIS NORTH EIS

Miramar filed a EIS with the NIRB in early 2003. The draft EIS provided details on the Doris North Project including the project description, environmental baseline studies, impact assessments, socio-economic considerations, environmental management plans and reclamation and closure plans, which responded to the NIRB guidelines issued in October 2002. The project was reviewed under a NIRB Part 5 review as provided under Article 12 of the Nunavut Land Claims Agreement (“NLCA”).

In late 2004, the “final” EIS was submitted and returned by NIRB with a request for more studies and information. The EIS was submitted again in late 2005 and on March 6, 2006, the NIRB recommended to the Minister of Indian and Northern Affairs Canada that the Doris North Project proceed. Once this recommendation is accepted by the Minister, the NIRB can

- 116 -

Watts, Griffis and McOuat

issue a project certificate, which will govern the conditions under which development of the mining and processing operation may proceed.

19.3 HEALTH AND SAFETY MATTERS

Miramar has a comprehensive, industry standard health and safety program in place. There is a small, well-equipped medical aid station at the Windy Lake camp and there is paramedic stationed in camp at all times. His or her services are available for Miramar and contractor personnel. There are also personnel on call in the camp, who normally fulfil other duties, trained and available to participate in an Emergency Response Team for search and rescue and medical emergency operations should this be required.

19.4 COMMUNITY RELATIONS

There are no inhabitants on the property, however, there are seasonal hunting and fishing camps in the vicinity. Miramar is in the process of moving a small employment office in Coppermine to Cambridge Bay and hosts at least one Inuit Elder site visit and information session once per year. There are numerous Inuit employees on site.

20. INTERPRETATION AND CONCLUSIONS

20.1 GENERAL AND EXPLORATION POTENTIAL

In a relatively short period of time, Miramar has succeeded in outlining significant Archean lode gold Mineral Resources hosted by several deposits/groups of deposits on the Hope Bay property. The gold mineralization is hosted within or very close to a major deformation zone, the DEFZ, similar in age and nature to the prolific Destor-Porcupine Fault Zone and Cadillac-Larder Lake Break in the Abitibi Belt of Central Canada. Such major deformation zones are known to host significant deposits on a regular, if not exactly predictable, basis.

The Hope Bay property is 80 km in strike length and a large portion of it remains relatively underexplored. Upwards of 75 surface showings and isolated anomalous drill intersections in favourable geological settings are being evaluated and plans prepared for systematically testing these targets. Detailed ground magnetic surveying is being carried out on some this winter and lithogeochemical data are being evaluated as appropriate. The targets will be prioritized, initially emphasizing targets on and near the DEFZ, and selective drilling will begin later in 2006.

It is WGM’s opinion that the Hope Bay property is underexplored and retains considerable potential for the discovery of additional gold deposits. Miramar’s programs are well focussed and managed, and strongly supported by senior management. The ingredients for further success are in place.

20.2 MINERAL RESOURCE ESTIMATES

WGM has audited the December 31, 2005 Mineral Resource estimates, as prepared by Miramar for the Naartok-Rand sectors of the Madrid Deposit Area and is satisfied that the estimates have been prepared in an acceptable manner and in compliance with the requirements of NI 43-101 and the CIM Standards. WGM accepts the results as supplied by Miramar.

- 118 -

Watts, Griffis and McOuat

21. RECOMMENDATIONS

21.1 GENERAL

Miramar has a comprehensive QA/QC program in place that in WGM’s opinion meets industry standards. The program includes provision for the re-assaying of sample batches under certain circumstances as described in Section 13.3.2. There are exceptions to these circumstances, such as only a small sample population of a particular standard (early in its history of use) and it is WGM’s opinion that the QA/QC program would be enhanced if exceptions were eliminated. Miramar should also consider introducing the regular inclusion of core duplicates into its QA/QC program.

21.2 MINERAL RESOURCE ESTIMATES

The December 31, 2005 Mineral Resource estimate for the Naartok-Rand sectors of the Madrid Deposit Area has been done using standard computer-based techniques i.e., solid modelling of interpreted mineralized zones, selection of assay intervals within solid intercepts and capping of high grade values for those intervals, compositing and block grade interpolation from composites by the inverse squared distance method, and finally categorization of block resources using a search criterion, which reflects the average drilling grid in various parts of each zone.

The strength of the procedure used by Miramar in this work is the detailed splitting of zones into panels of constant zone orientation and the adaptation of search ellipsoids to those local zone orientations.

In future Mineral Resource estimation work, it is recommended that within the existing orientation panels, the block interpolation be based on a more objective analysis of grade continuity in each of the most important zones through variography and some form of kriging. That alternative approach may generate different grade-tonnage curves, depending of the magnitude of a nugget effect and its influence on the smoothing of block grade estimates.

Watts, Griffis and McOuat

21.3 2006 WORK PLAN AND BUDGET

WGM has reviewed and supports Miramar’s 2006 work plan and budget.

Miramar plans to spend approximately $31 million at Hope Bay in 2006. The program will be directed toward two key objectives:

1.

To complete drilling and technical studies sufficient to define a second phase of development at Hope Bay following the proposed Doris North Project, which is now advancing through the permitting process. There are two scenarios being contemplated which define the range of future production, a) A 350,000 ounce per year combined open pit and underground operation, and b) A large open pit concept, which would determine if the northern-most part of the Madrid system can support a larger scale open pit operation potentially producing 500,000 – 750,000 ounces per year. This scenario would also incorporate high-grade feed from the Doris and Boston deposits; and

2.

Initiate a new exploration model for Hope Bay that focuses on the geological similarities including regional faults, alteration and mineralization with the Timmins and Larder Lake areas in Ontario and ensure sufficient exploration is completed on the Hope Bay belt to meet or exceed any assessment work requirements.

INDIVIDUAL PROJECTS

Madrid Deposit/Trend Area

Exploration will continue to focus on the Madrid area in 2006 with four major drill projects (Naartok Expansion, Naartok Infill, Suluk/South of Suluk and Rand/Bend), a trenching project (Naartok Trench) and a geological targeting project (Madrid Trend). Drilling in 2004 and 2005 has demonstrated that the previously separate deposits, Naartok, Perrin, Rand, Bend and Suluk are all part of a more or less continuous mineralized system now termed the Naartok System. The mineralization at Naartok East is open at depth and along strike to the north while Naartok West has limited expansion potential. Suluk and South of Suluk have potential to expand both north and south. The Rand/Bend area has the greatest potential to impact future development plans in the Madrid area by utilizing stratigraphy and potentially productive stratigraphic units (selected Patch Group rocks) to direct drilling. The Rand/Bend

- 120 -

Watts, Griffis and McOuat

areas are under-drilled, in particular at depths (below 200m) where both Suluk and Naartok have shown a marked increase in strength, grade and thickness.

Naartok Expansion

The objective is to extend mineralization to the north and to a lesser extent at depth. This is a continuation of the 2005 project and will test the depth and strike extensions of the Naartok East Zone, and to a lesser extent the Naartok West Zone. The Naartok East Zone may be flattening, i.e., extending north and not plunging to depth. Drilling will generally consist of 100 m step out holes and where successful these will be followed by infill drilling at approximately 50 m centres. The amount of drilling will be based on success. The current allocation of drilling is 14,000 m of which 4,000 will be directed to the Rand/Bend area.

Naartok Infill

The objective is to complete infill drilling at Naartok East and West to facilitate inclusion of drilling in the 2006 Mineral Resource estimates and to provide an upgraded Mineral Resource estimate to support development studies. The upper 225 m at Naartok East and the upper 250 m at Naartok West have been largely drilled to the level of Indicated Mineral Resources. It is planned to drill selected areas of these zones to better facilitate development studies including support future feasibility studies. In addition, the Naartok expansion project outlined above will require infill drilling to support Mineral Resource estimation. The 2006 project has been allocated 16,000 m of core drilling but the amount will be governed to some extent by the success rate in the Naartok expansion drill program. This includes 2,000 m of infill drilling in the Rand/Bend area.

Suluk/South of Suluk

The objective is to complete infill and expansion of Mineral Resource drilling and to extend the Suluk system north to link with Bend and as far south as possible. The Suluk deposit is under-drilled, particularly below 150 m and on the northern and southern “limits.” Also, there are some questions regarding the southern extension and the relationship of South of Suluk to the actual Suluk stratigraphic trend. The 2006 project has an allocation of 3,300 m, but this project will require further review as early compilations indicate at least a further 1,700 m will be required for a total of 5,000 m.

- 121 -

Watts, Griffis and McOuat

Rand/Bend Area

The objective is to complete infill and expansion of Mineral Resource drilling to establish the continuity of scattered drill results and if successful link up Naartok through to Suluk. This would have a major impact of the development potential of the Madrid area. Both Rand and Bend are under-drilled relative to Suluk and Naartok. Generally, intersections have tended to be lower grade but this is not unlike the upper portions of Naartok East or Naartok west away from the higher grade shoot area. Much improved geological understanding of the volcanic stratigraphy will guide the drilling. Current development studies have difficulties establishing open pits in this area primarily due to low density of drilling, incomplete sampling and less than ideal orientation of holes. There is little drilling below 200 m where both Suluk and Naartok have shown a marked increase in strength, grade and thickness. The 2006 drilling is projected at 6,000 m. As with other programs the ultimate program will depend on success.

Madrid Trend

The objectives for 2006 will be to successfully target and drill extensions of the Madrid trend utilizing conceptual targeting based on knowledge of the Madrid system and its similarities with mineralization in the Porcupine camp at Timmins and the Kirkland Lake-Larder Lake camps in Ontario. The Madrid trend as interpreted at his time extends from the Kink area west of Doris, south to the South Nexus area, a distance of 21 km. Initial studies have noted a number of distinct similarities in terms of host lithologies, alteration and mineralization. This project will document these similarities and identify drill targets on an ongoing basis during 2006. Limited mapping and geophysics will be carried out along with 10,000 m of drilling. The program will be expanded to include fence drilling on Wolverine and Patch lakes to explore for parallel zones of Madrid style mineralization and to profile the geology below the lake.

Naartok Trench

The objective is to expose overburden covered sections of Naartok mineralization for detailed study and sampling. There are no complete exposures of the mineralizing systems at Naartok due to overburden cover. A program to open up four trenches, two at Naartok East and two at Naartok West will allow geologists to make detailed observations regarding mineralization controls and structural settings, and provide exposure for detailed character sampling. The exposure could also be used for large metallurgical samples if warranted.

Watts, Griffis and McOuat

OTHER INDIVIDUAL PROJECTS

Doris Trend

The objective is to test selected portions of the Doris trend in the Doris connector area to determine if some of the mineralization has the same shallow rake as Doris central and test the Island Vein extension target. Detailed drilling at Doris central in 2005 outlined a shallower rake to the mineralization than previously interpreted. Targeting of the mineralization at Doris connector based on a steeper rake has generally returned mixed results. Also, a new interpretation of Doris central indicated that the Doris central mineralization may be the equivalent of the West Valley Wall veins occurring to the west of Doris North. If this interpretation is valid there may be a good exploration target, the Island Vein extension, further to the east in Doris Lake. Selected portions of the Doris connector system will be drilled to test for the presence of a shallow rake. Drilling of 3,300 m is planned. A few holes will be allowed to run further to the east to determine if the Island Vein extension has potential.

Boston B4

The B4 zone will be drilled to determine the broad extents of mineralization outlined in historical drilling. The presence of a significant volume of mineralization could enhance current development studies (underground or open pit). The B4 zone is parallel to and lies to the east of B3 and B2. Limited drilling has outlined local areas of continuous mineralization but gaps as big as 200 by 200 m exist without drilling. Generally the mineralization is weaker than B2 or B3 so overall impact will be minor but given the proximity to the other zones, the development of a significant Mineral Resource, on the order of +150,000 oz Au, could have a positive impact on development studies. A 3,000 m drill program scheduled for the break-up period will test for additional mineralization.

Regional Assessment (Work) Program

The objective is to complete a regional exploration program to develop and test priority targets in order to meet and slightly exceed assessment work requirements, to maintain the Hope Bay land package in good standing. Assessment requirements for 2006 total $1.1 million. Since Nunavut does not have a transferable credit system (whereby excess credits on one claim may be spread to other claims), exploration must be completed on each claim. The 2006 program will continue from the 2005 program, which was designed to

- 123 -

Watts, Griffis and McOuat

identify high potential corridors. A limited, 1,000 m drilling program will test the best targets late in 2006.

The estimated cost breakdown for the 2006 program is presented in Table 19.
