SUMMARY

New Polaris (formerly Polaris-Taku) is an early Tertiary mesothermal gold mineralized body located in northwestern British Columbia about 60 miles south of Atlin B.C. and 40 miles northeast of Juneau, Alaska. The nearest roads in the area terminate five miles due south of Atlin and six miles southeast of Juneau. Access at the present time is by aircraft. A short airstrip for light aircraft exists on the property but there is a larger strip along the Tulsequah River six miles away that can accommodate DC-3 planes if it is rehabilitated. The gold property consists of 61 contiguous Crown-granted mineral claims and one modified grid claim covering 2,100 acres. All claims are 100% owned and held by New Polaris Gold Mines, a wholly owned subsidiary of Canarc Resource Corp. subject to a 15% net profit interest held by Rembrandt Gold Mines Limited. Canarc can reduce this net profit interest to a 10 percent net profit.

 

The deposit is composed of three sets of veins (quartz-carbonate stringers in altered rock), the “A-B” veins northwest striking and southwest dipping, the “Y” veins north striking and dipping steeply east and finally the “C” veins east-west striking and dipping to the south to southeast at 65° to vertical. The “C” veins appear to hook around to the north and south into the other two sets of veins so that their junctions form an arc. The gold is occluded in finely disseminated arsenopyrite grains that permeate the altered wallrock and stockwork veins. The next most abundant mineral is pyrite, followed by minor stibnite and a trace of sphalerite. The zones of mineralization range from 50 to 800 feet in length and 1 to 45 feet in width. The gold values in the veins show remarkable continuity and uniformity.

 

Several consulting groups have estimated a mineral inventory for the property. Gary Giroux of Montgomery Consultants completed the last in 1995 in which he estimated 450,000 tons grading 0.365 oz/ton Au in a probable resource and 2,509,000 tons grading 0.365 oz/ton Au as a probable resource. Under the current guidelines of 43-101, this resource would be categorized as 450,000 tons grading 0.365 oz/ton Au as an indicated resource and 2,509,000 tons grading 0.365 oz/ton Au as an inferred resource. More recently, Canarc completed an in house mineral inventory estimate showing a larger resource but it need to be updated to follow Policy 43-101 with regard to resource estimation.

 

Canarc carried out programs in 1996 and 1997 following McKay’s recommendation of further drilling from surface and underground. A total of 44 drill holes were completed with 60 new intersections. The underground was dewatered, cleaned, mapped and sampled. The complete database was re-evaluated and modeled to identify extensions and new zones, which could be targeted by drilling.

 

The property warrants further work and it is recommended that Canarc Resource Corp commission two independent reviews; one to look at the metallurgy and the other to look at incorporating the new data into an updated mineral inventory. The goal is to move the property closer to a revised prefeasibility study. Further drilling will be required to define reserves along strike and at depth.

1.0 INTRODUCTION, TERMS OF REFERENCE and DISCLAIMER

 

Mr. Bradford Cooke, President of Canarc Resource Corp, commissioned this report in June 2002 to provide a summary of the exploration activity during 1996 and 1997. The report will be used to file an Annual Information Report (AIF) with the TSX Exchange. The author is familiar with the project having visited it on numerous occasions over the last 20 years, one of which was during the exploration program when an underground visit was made to evaluate the veins, review the drilling, core logging, sampling and handling of data. In addition, the author has reviewed the drill hole database, drill hole information on sections and plans.

 

The data from this report is based upon Canarc’s exploration program in 1996 and 1997, in which 73 diamond drilling holes were completed. The author reviewed the data on site and later in looking through the sections, level plans and digital database.

 

The author has not verified the legal surveying of the crown grants and mineral claim. The author has not verified the old resource estimates and has only made comments about the historic resource estimates and how they will compile with 43-101.

 

 

2.0 PROPERTY DESCRIPTION AND LOCATION

 

  ***Graphic not available - for more information, contact Philip Yee, Canarc Resource Corp. (604) 685-9700***

 

 


 

The New Polaris (formerly the Polaris-Taku mine) properly consiting of a group of 61 contiguous crown grants and one modified grid claim totaling 2,956 acres located 60 miles south of Atlin, B.C and 40 miles northeast of Juneau, Alaska is 100% owned by New Polaris Gold Mines, a wholly-owned subsidiary of Canarc Resource Corp of Vancouver B.C. Located at approximately 133°37’W Longitude and 58°42’N Latitude, the deposit lies in close proximity to the “Tulsequah Chief” property of Redcorp on the eastern flank of the Tulsequah River Valley (Figure 1).

The claims are 100% owned and held by New Polaris Gold Mines, a wholly owned subsidiary of Canarc Resource Corp. subject to a 15% net profit interest held by Rembrandt Gold Mines Limited which Canarc has the right to reduce to 10%. The claims locations are shown on Figure 2 while Table 1 summarizes the claims shown on Figure 2. The author has not ascertained if the property has been legally surveyed.The mineralized areas are shown on Figure 4, which shows the geology of the property and the mineral showings. Notice of work for the program will be required before work on the property can start.

3.0 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY

 

The New Polaris project area lies on the eastern flank of the steep, rugged, Coast Range Mountains. Relief is on of extreme with elevations ranging from sea level to 8,500 feet.  It has the same physical features charactristic of the coastal section of the Alaska Panhandle.

 

 

 

  ***Graphic not available - for more information, contact Philip Yee, Canarc Resource Corp. (604) 685-9700***

 

 

 

Extensive glaciation of recent age has been the dominant factor in topographic development. The Taku and Tulsequah Rivers, which dissect the area, provide its most striking features, with their broad valleys bounded by steep mountains. Numerous tributary streams flow from valleys filled with glaciers. The majority of the glaciers are fingers branching from the extensive Muir ice cap, lying to the northwest of the Taku River. The Tulsequah glacier, which terminates in the Tulsequah valley about ten miles north of the New Polaris mine site, is one of the largest glaciers in the immediate area. It forms a dam causing a large lake in a tributary valley that breaks through the ice barrier (Jokülhlaup) during the spring thaw every year, flooding the Tulsequah and Taku valleys below for three to five days.

Small aircraft provides access from Atlin or Juneau. Ocean-going barges have been used in the past to access the site when heavier equipment is required. Redfern has applied to complete a road to their project site, which could change the infrastructure to the site. The property can be operated year round. Access would be difficult during break up and freeze up.

 

The climate is very characteristic of this section of the British Columbia coast, with heavy rainfall prevailing during the late summer and fall months, and comparatively heavy snowfall, interspersed with rain during the winter. The annual precipitation is approximately seventy-five inches of which twenty-eight inches occurs as rainfall. The snow seldom accumulates to a depth greater than five feet on the level. Winter temperatures are not severe and rarely fall below 10 degrees below zero Fahrenheit. Summer temperatures in July average 60°F with daytime temperatures reaching the high 80’s on occasion. The vegetation is typical of northern temperature rain forest, consisting primarily of fir, hemlock, spruce and cedar forest on the hillsides and aspen and alder groves in the river valley.

 

5.0 HISTORY

 

From 1923 to 1925 the Big Bull and Tulsequah Chief properties were discovered along the east side of the Tulsequah River and opened up the Taku River district. In 1930, Noah A. Timmins Corporation optioned some of the claims that make up the New Polaris property and conducted trenching and diamond drilling in 1931. The trenching exposed a number of veins of which 10 showed promising grades. A short exploration adit (about 30 feet long) was also driven into the side of the hill and Timmins drilled 19 holes for a total of 5297 feet but was unable to correlate the intersections and elected to drop the option in September 1932.

 

The Alaska Juneau Gold Mining Company then optioned the property and conducted underground exploration from the “AJ” (Alaska Juneau) adit. Alaska Juneau drove a total of 625 feet of drifting and, although they intersected “ore grade” mineralization, they too had problems with correlation and dropped the property in the fall of 1934.

 

H. Townsend and M.H. Gidel of the Anaconda Corporation examined the property in 1934 carefully mapping the showings. They came to the conclusion that commercial ore bodies existed even though these showed irregularity due to faulting. Samples were sent to Geo G Griswold in Butte Montana who obtained gold recoveries from flotation tests in the order of 88 percent.

 

D.C. Sharpstone then secured an option on the property on behalf of Edward C. Congdon and Associates of Duluth, Minnesota. Congdon conducted 775 feet of underground exploration in the “AJ” tunnel and collared 85 feet into the Canyon adit. The Polaris-Taku Mining Company was then incorporated in 1936 to take over the property from Congdon. Polaris-Taku erected a 150-ton per day flotation mill in 1937 and mined underground continuously until it was closed down in April 1942 due to labour restrictions brought on by the Second World War. Mining Operations resumed in April 1946 and continued until 1951 when the mine was closed due to high operating costs, a fixed gold price and the sinking of a concentrate barge shipment during a storm in March 1951.

 

An Edwards roaster and a cyanide plant to produce bullion were installed and tested in1949 in order to improve recovery and reduce shipping cost of concentrates to the Tacoma smelter. The addition of the roaster helped improve milling economics, but its capacity was somewhat limited as it could treat only about 45% of the concentrates produced from the flotation plant. After closure the mill was leased to Tulsequah Mines Ltd. (owned by Cominco) who modified it to process 600 TPD of massive sulphide polymetallic ore (containing gold, silver copper, lead and zinc) from the Tulsequah Chief and Big Bull Mines. Tulsequah Mines Ltd used the mill from 1953 to 1957.

Numalake Mines acquired the property in 1953, changed their name to New Taku Mines Ltd and undertook rehabilitation work of the mine’s plant. A negative feasibility study in 1973 halted this work. New Taku changed its name to Rembrandt Gold Mines Ltd in 1974. The property lay idle until Suntac Minerals Corp. optioned the property in 1988 and started surface exploration. Canarc merged with Suntac in 1992 and bought out Rembrandt’s interest in 1994 and has continued exploration up to the present. The Canarc’s subsidiary New Polaris Gold Mines (formerly Golden Angus Mines Ltd.) currently operates the property.

 

6.0 MINE DEVELOPMENT - HISTORICAL

 

The upper areas of the mine were developed on five levels: Canyon (elev. 580 feet. ASL), C (elev. 482 feet ASL), B (elev. 364 feet ASL), AJ (elev. 246 feet ASL), and Polaris (elev. 136 ASL). All levels except C level have been developed by adits. A vertical, three compartment timbered shaft, measuring 16-10” x 6-2”, was sunk in 1940 from the AJ level to a depth of 900 feet, from which the 150, 300, 450, 600, and 750 levels were driven to provide access to the lower portion of the deposit. The 750 Level shaft station was cut; however, the level remains undeveloped. The annual development and diamond drilling statistics are summarized in Table 2. The dewatering completed in 1996 and 1997 provided access down to the 300 level.

 

The Polaris Level was used as the main access and haulage way. Ore was directed to the Polaris level via chutes from the upper levels and hoisted from the lower levels. An Ingersoll Rand 48 x 36 inch double drum hoist equipped with a 125 HP motor hoisted men and materials at 580 feet per minute using a skip over cage arrangement. The hoist was located on the AJ level and was connected to the shaft via a horizontal ropeway. Past mining consisted primarily of conventional shrinkage stope methods although some cut and fill and open stopping methods were used where appropriate. Ground conditions are reported to be good, with little timbering required. This was verified when the dewatering was completed in 1997.

A summary of historical annual production statistics is shown in Table 3 where the grades on the second start up appear to be higher in general than the earlier mining which may reflect higher grades at depth, or high cutoff grades or better metallurgical recoveries.

7.0 1988 to 1995 DIAMOND DRILLING

 

Exploration drilling from 1988 to 1995 consisted of 104,380 feet in 129 holes. The first holes tested the “Y” vein system either down dip or along strike from old workings. The discovery of the “C” Vein system in 1989 resulted in a refocusing of efforts towards defining these veins. Drilling in 1994 and 1995 was designed to test the North Zone and the downward continuity of the “C” Zone. The “C” veins received the bulk of exploration attention during this phase. These “C” veins may represent a structural knot discovered on the lower levels immediately prior to cessation of operations in 1951. It exhibits good grade over significant widths approaching 45 feet in places and reportedly appears to be more consistently mineralized than the other veins. Table 4 summarizes the drilling completed from 1988 to 1995 and outlines the targets for these holes.

Table 4 - 1988-1995 Drilling

 

 

Drilling on the “Y” Vein system has confirmed its existence and continuity at depth and, although it is high grade in places, its character is generally narrow and consists of at least 12 different “lenses”.

 

8.0 GEOLOGY

 

The geology has been taken from regional reports, company reports and the author’s trips to the project over the last 20 years. The author worked in the area from 1980 to 1986 on a continuous basis and on an infrequent basis to the present time.

 

8.1 Regional

 

The New Polaris Mine lies on the western edge of a large body of Upper Triassic Stuhini Group volcanic rocks, which has been intruded by a Jurassic-Cretaceous granodiorite body north of the mine. Older Triassic volcanic rocks and earlier sediments underlie the Stuhini volcanic rocks. The granodiorite is part of the Coast Plutonic Complex (see Figure 3).

The structural trend in the area is northwest-southeast, paralleling major faults and folds to the east and the intrusive alignment to the west. The Triassic volcanic rocks and older sedimentary rocks have been folded and sheared with the Stuhini Group rocks being deformed into broad to isoclinal, doubly plunging symmetrical folds with large amplitudes.

 

8.2 Property

 

The gold deposit is hosted within an assemblage of mafic (basalt and andesite units) volcanic rocks altered to greenschist metamorphic facies (see Figure 4). The orientation of these units is inconclusive because there are no marker beds in the sequence. It is thought that the units are steeply dipping (70o to 80o ) to the north based on the orientation of the limestone/basalt interface at the southern portion of the property.

 


8

 

A serpentinite unit is located to the northeast, which was identified in recent (996/97) drilling and underground mapping. This unit appears to form the eastern extent of the mineralization. The age relationship is unclear, but it is assumed that the serpentinite is a later stage feature possibly associated with the tectonism in the area.

 

The ‘vein’ zones are structurally controlled shear zones and are typified by silicification and carbonitization cross cutting actual quartz-carbonate veins. These zones have sharp contacts with the wall rock and form anastamosing ribbons and dilations. These zones have been deformed several times, which makes original textures difficult to determine. The zones are generally tabular in geometry forming en-echelon sheets within the more competent host lithologies.

 

All of the strata within the property have been subjected to compression, rotation, and subsequent extension. The plunge of folds appears to be variable though generally shallow. Small-scale isoclinal folds strike north-northwesterly and plunge moderately to the north. Numerous faults are found on the property, the more significant of which are discussed later.

 

The possible extension of the Llewellyn fault, termed the South Llewellyn fault, continues south from the Chief Cross fault along mine grid coordinate 4400 East. Slightly north of Whitewater Creek it is offset to the west by an east-west fault, the 101 fault, to continue in a more southeast orientation on the opposite side of Whitewater Creek. This northwest-southeast oriented structure was named the Limestone Fault due to its bedding parallel attitude within a discontinuous limestone/marble horizon.

It marks the southwest boundary of the “mine wedge”; the wedge shaped package of rock within which all past production took place. The northern boundary of the “mine wedge” is further defined as mentioned above by the Whitewater Creek Schist Zone, a zone of schistose chlorite-amphibolite-serpentinite less than 300 feet thick. A complex network of brittle faults is also found within this zone.

 

Three major faults, Numbers 1 and 5, and an unnamed fault, lie within the mine wedge. The No.1 and No.5 faults strike northwest-southeast, dipping approximately 45° to the northeast, and are sub parallel to the unnamed fault, which dips steeply to the southwest. The No.1 fault has reverse displacement of up to 100 feet while the displacement of the No. 5 fault is poorly defined. The southwest dipping, unnamed fault shows no displacement, as it apparently parallels the A-B vein system. The mined-out areas indicate the wedge shape, the predominant orientations and continuity of the zones, and the overall plunge of the system to the southeast. An early interpretation of the structure shows that various veins appear to meet and form “junction arcs” where both thickness and grade improve.

 

 

 

 


10

The most predominant vein orientations are: northwest striking and southwest dipping, the “A-B” veins; north striking and east dipping, the “Y” veins; and the less extensive but economically important east to northeast striking and south dipping zones at the intersection of the previously mentioned vein sets. These zones were accordingly termed “junction arcs” and are known as the “C” veins. Up to 80% of total past production came from within 300 feet to either side of these junction arc centerlines.

 

9.0 1996 to 1997 DIAMOND DRILLING AND GEOLOGICAL MODELLING

 

The program included geological modeling using the Gemcom software to properly understand the historical data and put it into perspective. This was followed up by approximately 39,000 feet of diamond drilling from underground to test the targets identified by the modeling.

 

Table 5 outlines the intersections identified during the modeling which are open and have not been added to any mineral inventory estimate in the past. No mineral estimation has been calculated utilizing these intersections. They are an example of what can be found in many old mines when the assay data is carefully evaluated and combined with geological data.

 

Table 5 - Additional Underground and Surface Intersections Identified from Historic data.

The drilling planned for 1996 and 1997 was carried out from underground. It initially started in the upper levels of the mine following up some of the intersections and areas outlined in Table 5. A complete list of all the diamond drill holes completed during this phase is shown in Table 6. A total of 73 holes were drilled over the two years with a total footage of 39,611.5 feet. The drilling was carefully planned to increase the knowledge and confidence of parts of the past mineral estimations. The lower price of gold caused the program to finish prior to all of the targets could be tested.

 

Dewatering of the lower levels from the Polaris haulage way down was undertaken during the early drilling. It was completed in approximately 6 months. Each level was evaluated as it was dewatered and if necessary, rehabilitated. In many cases the ground was in excellent condition and very little rehabilitation was required prior to washing down the walls. Mapping and sampling of the levels was completed.

Diamond drilling in 1996 was focused on the AJ level in the mine targeting the “A - B” veins and the “Y” veins. This drilling was targeted at extension of known shoots defined from mining and earlier

drilling. A total of 21 intersections were obtained from these 24 drill holes. These intersections are included in the company database and are shown on the attached level plans and longitudinal sections. The mineralization is intersected by these holes is typical of the A-B Vein sets.

 

Table 7 - 1996 Drill Hole Intersections

 

 

In 1997, another 49 diamond drill holes were completed for a total footage of 29,097 feet. The intersections for this drill program are outlined in Table 8 and make up 48 separate vein intersections. These holes as can be seen on Table 6 are in the lower portion of the mine from the AJ, Polaris and 150 levels. The best intersection from the drilling program was obtained in the second last hole 97-44 where 112.2 feet grading 0.42 oz/ton Au was intersected. This intersection was on the “C” vein system where the grades appear to be higher and more consistent. The thickest intercepts have been obtained from the “C” veins. These holes and intersections are all in the database for the project.

 

Table 8 - 1997 Drill Hole Intersections

 

 


 

15

 

 

Table 9 lists the underground sampling that was completed on the AJ level during the mapping and sampling program. Since the program was cut short in 1997 some of the levels were not mapped and sampled. It is obvious from these few samples that more sampling could be beneficial to providing additional data points in any future estimation. The lower levels cannot be reached again until the mine is dewatered.

Table 9 - Underground Sampling

 

 

These samples have been added to the database for future estimations of the mineral resource.

 

10.0 MINERALIZATION

 

Mineralization of the New Polaris deposit bears strong similarities to many Archean Lode gold deposits such as the arsenical gold camp of Red Lake, Ontario where the gold-bearing arsenopyrite is disseminated in the altered rock and in quartz-carbonate stringers.

 

The vein mineralization consists of arsenopyrite, pyrite, stibnite, and gold in a gangue of quartz and carbonates. The sulphide content is up to 10%, with arsenopyrite the most abundant, and pyrite the next important. Stibnite is fairly abundant in some specimens but overall comprises less than one-tenth of 1% of the vein matter. Alteration minerals include fuchsite, silica, pyrite, sericite carbonate and albite.

 

In general, the zones of mineralization ranging from 50 to 800 feet in length with widths up to 45 feet appear to have been deposited only on the larger and stronger shears. Their walls pinch and swell showing considerable irregularity both vertically and horizontally. Gold values in the veins show remarkable continuity and uniformity, and are usually directly associated with the amount of arsenopyrite present. The prominent strike directions are north-south and northwest-southeast with weaker control of the vein systems, which is interpreted to be within a major shear zone. Up to 80% of the mine productions was from “structural knots” or what is now known as “C” zones. In detail, the C zones are arcuate and lensoid structures, while the A-B zones are regular and planar and the Y zones are irregular and planar. Figure 5 shows a 3-D view of the veins.

 

11.0 MINERAL RESOURCES - HISTORICAL

 

The previous resource calculations were reviewed to identify the order of magnitude of the “resource”. Although all of the estimations were made prior to Policy 43-101 being implemented, the estimations are useful as a guide to an order of magnitude for the resource.

 

An estimate of New Polaris reserves was made prior to closure in 1951, where i) “reasonably assured” ore was projected 25 feet in the plane of the vein above and below sampled drift sections of minable grade, ii) while “possible” ore was projected an additional 25 feet beyond these confines (Parliament 1949). These reserves were based solely on underground sampling. The “remaining reserves” at the time of closure were 105,000 tons grading 0.42 ounces of gold per ton including 17% dilution. Estimates after this have included parts of this estimate. No other information is available about this estimation.

 


17

 

Adtec Mining Consultants (1972) recalculated these “reserves”. These were recalculated to be 148,000 tons of 0.29 oz/ton Au based on similar definitions and existing mine drawings and assay plans. Adtec Consultants (1983) recalculated the remaining “reserves” within the mine workings and defined these to be in the order of 223,000 tons grading 0.32 oz/ton Au (diluted) based on a 0.15 oz/ton Au cutoff and a minimum mining width of 4 feet. These reserves were subdivided into 151,000 tons of “assured” and 72,000 tons of “reasonably assured” reserves.

 

The resources were recalculated by Beacon Hill in 1988 for Suntac Minerals Corporation using a minimum mining width of 5 feet (instead of 4 feet) with similar results. Their resource estimate was “limited to those areas where continuous sampling data was available along drifts, raises and stope backs, etc and where it appears that minimal development work would be required to access the resource”. That calculation showed a total probable and possible resource of 244,420 tons grading 0.33 oz/ton Au with 132,210 tons grading 0.33 oz/ton Au classed as probable and 112,210 tons at 0.32 oz/ton Au classed as possible. In 1989, Beacon Hill added further probable and possible mining resource from 27 drill holes completed by Suntac. They estimated that the drilling had increased the resource by 380,000 tons grading 0.39 opt (probable) and 820,000 tons grading 0.39 opt (possible) which, added to their previously calculated resource, brought the overall resource potential up to 1,450,000 tons grading 0.38 opt (diluted) above the lowest worked level of the mine (600 level at elevation - 462 feet Below Sea Level ‘BSL’). Table 10 summarizes these estimations.

 

Montgomery Consultants were commissioned to conduct a geostatistical estimation of the geological resource for the Polaris-Taku Deposit in 1991. G.H. Giroux carried out this review and calculated a total resource of 2,225,000 tons grading 0.433 oz/ton based on a geostatistical approach using a cut-off grade of 0.25 oz/ton Au (Table 11). These resources were divided into 333,000 tons grading 0.437 oz/ton Au (probable) and 1,892,000 tons grading 0.432 oz/ton (possible). The calculation discounted much of the reserves around the old workings and did not include dilution and minimum mining width provisions. These calculations were based on both old and new drilling and extended the resource base down to roughly 1200 feet BSL.

Watts, Griffis, and McOuat were contracted to review the previous resources in August 1992. Their review incorporated the residual resources within the mine workings, as calculated by Beacon Hill in 1989, into their overall estimate of a total (diluted) mineral resource of 1,600,000 tons at 0.46 oz/ton Au. Their calculations were based upon a minimum mining width of 5 feet or 15% dilution and a cut-off grade of 0.25 oz/ton Au. The improvement in grade stems from the inclusion of new deeper holes that extend the known mineralization to a depth of 1200 feet BSL and exclusion of lower grade material previously included in the Montgomery estimate.

 

Giroux was further contracted to provide resource updates throughout 1992 and in February 1995 he recalculated the resources for the deeper drilled portions of the “C” Zone. The total resources calculated by Giroux are summarized on Table 11. His calculations are based on an in-situ estimation with a 0.25 oz/ton Au cut-off. He did not include any of the North zone drilling.

 

The Giroux estimate outlined in Table 11 is the most up to date mineral inventory estimation, which includes what was left in the mine when it was closed and the new areas identified in drilling up to 1995. Although these estimations were complted prior to the implementation of National Policy 43-101 they can conform with the Probable Resource used by Giroux being called an Indicated Resource and the Possible Resource would be an Inferred Resource. This was confirmed by a telephone conversation between the author and Gary Giroux during the preparation of this report.

A new mineral inventory is warranted to add in the additional intersections identified in the geological modeling, the new intersections obtained during the 1996 and 1997 diamond drilling programs. At this time it would be beneficial for the project to re-classify the resource estimates so that they conform to National Policy 43-101.

 

Although the vein intersection require significant modeling and drilling to confirm vein continuity there are many vein intersections both in the old drilling and underground sampling and the new drilling that supports continuity. The stopes from the earlier mining also suggest good continuity of the vein systems even though they appear to have focused on mining the higher grades as evidenced by what was left on the edge of some of the stopes. The C zone is an area where significant widths have been obtained in drill holes and underground, which could develop tons quickily if continuity is demonstated.

 

12.0 SAMPLING , CORE HANDLING AND DATA VERIFICATION

 

12.1 Procedure

 

The core was logged and stored in the camp. Access to be core was only available to the geologists and the core sampler. The core was brought from the drill set up to the logging facility by the drill helper at the end of each shift. The core was geologically and geotechnically logged, recoveries calculated, and samples marked out. The core was passed to the sample cutter who cut with a regular core splitter each sample individually, wrapped them in plastic bags for shipment. The sample intervals were easily identified and correlate well with the drill logs. In the opinion of the author the sampling was properly done and every care taken to protect the secure the core but also make it clear where every sample originated. As a result when assays were received it was very easy to see why a sample had a particular value.

 

The samples where shipped out on the back-haul by supply planes to Atlin and sent by truck to Whitehorse to Northern Analytical based in Whitehorse. Northern Analytical is a reputable laboratory that the author has used on many occasions for assaying of core and rock samples from other projects. The author has found that check assays completed in the past are reliable within 5%.

 

Samples were analysed for gold (Au) by Fire Assay (FA) with an Atomic Adsorption analysis to provide an actual value for the sample. Although no sample blanks or standards were submitted during the project, the laboratory routinely checked every 20th sample and automatically re-analysed every assay over 0.2 oz/ton Au. The sampling and analysis was being done at industry normal standards for the date when the program was running. The laboratory was fully certified and accredited for gold analysis.

 

Assay sheets have been evaluated by the author and compared with the database and were accurately transposed into the database. The core-logging sheets have been compared to the digital logs to check for accuracy. All sampling in the core was carefully laid out using geological parameters. The author talked to Peter Karelse and David Watkinson who supervised the drilling program and were responsible for all of the work completed at the New Polaris property.

13.0 CONCLUSIONS AND RECOMMENDATIONS

 

The New Polaris project has been on hold since 1997 pending an increase in the gold price and a resolution of the permitting of Redcorp’s “Tulsequah Chief” project. This high grade past producer has had a significant amount of work since the mine closed including additional drilling from surface and underground that outlined further resources, last calculated in 1995. Subsequent work in 1996 and 1997 obtained 65 new vein intersections and modelling identified over 69 intersections, which have not been included in a resource estimate. Although the program stopped before all of the drilling could be completed, in the authors opinion the program was successful in identifying more mineralised intercepts within the previously mined area. The program fell short before it could clearly demonstrate continuity to depth of the mineralization on the C zone. In the opinion of the author, the next phase of drilling should focus on connecting the deeper drilling with the near surface drilling and demonstrate continuity. The mineralization in the “C” veins appears to have significant width potential as evidenced by the second last drill hole in 1997 which obtained an intersection of 112.2 feet grading 0.42 oz/ton Au.

 

The style of mineralization and the gold association at Polaris appears to be similar to the reported mineralization in the Red Lake camp in Ontario. Gold is associated with arsenopyrite, pyrite, stibnite and rare sphalerite. The mineralization appears to be refractory, with gold occluded in arsenopyrite.

 

In the current climate of increasing gold price above $300/ounce, it is worth activating the project.

 

The author recommends that further metallurgical testing be completed to evaluate the potential for enhanced recoveries of gold, further drilling to test the continuity of the “C” zone mineralization at depth and tie this deeper mineralization with the upper portion of the mine and an updated mineral inventory to re-calculate the resource under Policy 43-101 guidelines. The drilling should be completed from surface with a large drill rig. It is recommended that approximately 8 holes be completed for approximately 12,000 feet, this would provide an indication of the continuity and if successful then further drilling would be warranted to upgrade the resource in this area.

 

An estimate of the costs of the first phase is as follows:

 

Metallurgical testing $20,000 

Mineral Estimation $30,000 

Surface Drilling $500,000

 

Total $550,000

 

A second phase of drilling would be recommended if the first phase is successful. It is suggested that approximately $2 million be available for this drilling program so that a higher confidence level for the mineral estimation can be attained.

 


     21 

 

The author is of the opinion that these phased programs are justified on the property because they will enhance the level of confidence of the next mineral estimation and provide valuable data about the amenability of the mineralization to various mineral extraction methods. The extraction methods will impact the economic viability of the mineralization and is required to assist in further evaluations of this property.
