Notes to the Consolidated Financial Statements

For the nine months ended March 31 2010 (Unaudited)

(stated in Canadian dollars)

1.

NATURE OF OPERATIONS

Portal Resources Ltd. was incorporated on August 14, 2000 under the Company Act of the Province of British Columbia.  

The Company is an exploration stage company whose business activity is the exploration of mineral rights located in Mexico, and the exploration of oil and gas in central Alberta, Canada. The Company has not yet determined if any of these rights contain economic mineral reserves, oil or gas reserves, and, accordingly, the amounts shown for deferred exploration costs represent costs incurred to date, less write-downs, and do not necessarily reflect present or future values.  The recovery of these amounts is dependent upon the discovery of economically recoverable reserves, the ability of the Company to obtain the necessary financing to complete the exploration of the rights, and upon the commencement of future profitable production or, alternatively, upon the Company’s ability to dispose of its interests on an advantageous basis. To date, the Company has not earned significant revenues and has an accumulated operation defici t of $14,502,930.

Current economic conditions have limited the Company’s ability to access financing through equity markets and this has created significant uncertainty as to the Company’s ability to fund ongoing operations for the next operating period.

The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and the classification of liabilities that might be necessary should the Company be unable to continue in the normal course of business.

2.

SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation and principles of consolidation

These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in Canada (Canadian GAAP). These interim consolidated financial statements have been prepared in accordance with the accounting policies described in the Company’s annual consolidated financial statements, do not include in all respects the annual disclosure requirements of generally accepted accounting principles, and should be read in conjunction with the most recent annual consolidated financial statements. The differences between those principles and the ones that would be applied under U.S. generally accepted accounting principles (U.S. GAAP) are disclosed in Note 14.

References to the Company are inclusive of the Canadian parent company, its wholly owned U.S. subsidiary, Portal Resources US Inc., and its formerly owned subsidiary Portal del Oro S.A.  All significant inter-company transactions and balances have been eliminated.

The accounting policies followed by the Company are set out in Note 2 to the audited consolidated financial statements for the year ended June 30, 2009 and have been consistently followed in preparation of these interim consolidated financial statements, except with respect to the following new and revised accounting standards which the Company is required to adopt under Canadian GAAP for interim and annual financial statements relating to its fiscal year commencing July 1, 2009.

New accounting policies

CICA Handbook Section 3862 “Financial Instruments – Disclosure” requires an entity to classify fair value measurements using a fair value hierarchy that reflects the significance of inputs used in making the measurements. The accounting standard establishes a fair value hierarchy based on the level of independent, objecting evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. CICA Handbook Section 3862 prioritizes the inputs into three levels that may be used to measure fair value:

SIGNIFICANT ACCOUNTING POLICIES, (Continued)

New accounting policies, (Continued)

a)

Level 1 – Applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

b)

Level 2 – Applies to assets or liabilities for which there are inputs other than quoted prices included in Level 1 that are observable for the assets or liability, either directly such as quoted prices for similar assets or liabilities in active markets or indirectly such as quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions.

c)

Level 3 – Applies to assets or liabilities for which there are unobservable market data.

The Company’s financial instruments consist principally of cash, short term investments, GST receivable, accounts payable and accrued liabilities. Pursuant to CICA Handbook 3862, fair value of assets and liabilities measured on a recurring basis include cash and short term investments determined based on Level 1 inputs, which consist of quoted prices in active markets for identical assets. The Company believes that the recorded values of all the other financial instruments approximate their current fair values because of their nature and respective maturity dates or durations.

Accounting Policies Not Yet Adopted

Convergence to international Financial Reporting Standards (“IFRS”)

In February 2008, the CICA announced that Canadian GAAP for publicly accountable enterprises will be replaced by International Financial Reporting Standards (“IFRS”) for fiscal years beginning on or after January 1, 2011. Companies will be required to provide IFRS comparative information for the previous fiscal year. The transition date of July 1, 2011 will require the restatement for comparative purposes, amounts reported by the Company for the year ended June 30, 2011, for which the current and comparative information will be prepared under IFRS.

The Company has commenced its IFRS conversion project in 2008. The Company’s IFRS project consists of three phases – scoping, evaluation and design, and implementation and review. The Company has commenced the scoping phase of the project, which consists of project initiation and awareness, identification of high-level differences between Canadian GAAP and IFRS and project planning and resourcing. The Company has completed a high level scoping exercise and has prepared a preliminary comparison of financial statement areas that will be impacted by the conversion.

A detailed assessment of the impact of adopting IFRS on the Company’s consolidated financial statements, accounting policies, information technology and data systems, internal controls over financial reporting, disclosure controls and procedures, and the various covenants and capital requirements and business activities has not been completed. The impact on such elements will depend on the particular circumstances prevailing at the adoption date and the IFRS accounting policy choices made by the Company. The Company has not completed its quantification of the effects of adopting IFRS. The financial performance and financial position as disclosed in our Canadian GAAP financial statements may be significantly different when presented in accordance with IFRS.

Business combinations

In January 2009, the CICA issued the new handbook Section 1582, “Business Combinations” effective for fiscal years beginning on or after January 1, 2011. Earlier adoption of Section 1582 is permitted. This pronouncement further aligns Canadian GAAP with US GAAP and IFRS and changes the accounting for business combinations in a number of areas. It establishes principles and requirements governing how an acquiring company recognizes and measures in its financial statements identifiable assets acquired, liabilities assumed, any non-controlling interest in the acquisition, and goodwill acquired. The section also establishes disclosure requirements that will enable users of the acquiring company’s financial statements to evaluate the nature and financial effects of its

(stated in Canadian dollars)

SIGNIFICANT ACCOUNTING POLICIES, (Continued)

business combinations. Although the Company is considering the impact of adopting this pronouncement on the consolidated financial statements, it will be limited to any future acquisitions beginning in fiscal 2012.

Consolidated financial statement and non-controlling interests

In January 2009, the CICA issued the new handbook Section 1601, “Consolidated Financial Statements”, and Section1602, “Non-controlling Interests”, effective for fiscal years beginning on or after January 1, 2011. Earlier adoption of these recommendations is permitted. These pronouncements further align Canadian GAAP with US GAAP and IFRS. Sections 1601 and 1602 change the accounting and reporting for ownership interest in subsidiaries held by parties other than the parent. Non-controlling interests are to be presented in the consolidated statement of financial position within equity but separate from the parent’s equity. The amount of consolidated net income attributable to the parent and to the non-controlling interest is to be clearly identified and presented on the face of the consolidated statement of income. In addition, these pronouncements establish standards for a change in a parent’s ownership interest in a subsidiary and the valuation of retained non-controlling equity investments when a subsidiary is deconsolidated. They also establish reporting requirements for providing sufficient disclosures that clearly identify and distinguish between the interests of the parent and the interests of the non-controlling owners. The Company is currently considering the impact of adopting these pronouncements on its consolidated financial statements in fiscal 2012 in connection with the conversion to IFRS.

3.

SHORT TERM INVESTMENTS

Short term investments consists of highly liquid investments, including guaranteed investment certificates with major financial institutions, having a maturity of 12 months or less at acquisition and that are readily convertible to contracted amounts of cash.

4.

MARKETABLE SECURITIES

On May 29, 2009 Portal Resources US Inc. acquired 150,000 shares of Pengram Corporation (“Pengram”) in return for assigning all of its interest in an option agreement.  At March 31, 2010, the fair value of the Pengram shares was $15,237 (June 30, 2009 - $ 34,875). During the year the Company recorded an unrealized loss of $19,638 (June 30, 2009 - $6,229).

UNPROVEN MINERAL RIGHTS

Argentina

As at May 14, 2009, the Company held a subsidiary and mineral properties in Argentina. During the most recent completed fiscal year the Company after reviewing work done on the properties, concluded that the potential did not justify further work and renounced the mining rights held under the projects. As such the project expenditures were written off and subsequently Portal’s Argentinean subsidiary was sold.

United States

On September 2, 2008, the Company announced that it had entered into an option agreement under which it has the right to acquire, from Claremont Nevada Mines, Scoonover Exploration and JR Exploration, three properties located in the Walker Lane Belt and Battle Mountain/Eureka Trend in Nevada, USA.

On May 29, 2009, the Company closed an Assignment Agreement with Pengram Corporation (“Pengram”) to transfer all the rights on the Nevada claims, in exchange for 150,000 shares of Pengram’s common stock. The Company has no further commitments on the Nevada properties (See Note 4 – Marketable Securities).

The Company accounts for its option grants in accordance with the fair value method of accounting for stock-based compensation.  For the nine months ended March 31, 2010, the Company recognized $95,439 (2009 - $17,789) in stock-based compensation for employees, directors and consultants.

The fair value of the options has been calculated using the Black-Scholes option-pricing model, based on the following assumptions:

	Years ended June 30,
	2009	2008	2007
Stock compensation	$      21,811	$    147,744	$      340,206
Risk-free interest rate	1.50% - 2.90%	4.00%	3.4% – 4.6%
Expected stock price volatility	121% - 227%	74%	49% - 76%
Expected option life in years	5 years	1 year	3 years
Expected dividend yield	Nil	Nil	Nil

Option prices models require the input of highly subjective assumptions regarding the expected volatility and expected life. Changes in assumptions can materially affect the fair value estimate, and therefore, the existing models do not necessarily provide the reliable measure of the fair value of the company’s stock options at the date of grant.

A summary of changes to stock options outstanding is as follows:

	March 31			June 30
	2010			2009
		Weighted Average			Weighted Average
	Number of shares	Exercise Price	Number of shares		Exercise Price
Outstanding at beginning of period	3,688,600	$0.35	2,753,600		$0.54

Forfeited or cancelled	(825,000)	$0.50	(1,197,200)		$0.44
Outstanding at end of period	3,683,600	$0.28	3,688,600		$0.35

FINANCIAL INSTRUMENTS

The fair values of the Company’s cash and cash equivalents, marketable securities, short-term investments, amounts receivable, accounts payables and accrued liabilities approximate their carrying values.

The Company’s financial instruments are exposed to certain financial risks, including currency risk, credit risk, liquidity risk and interest risk.

(a)

Currency risk

The Company may have property interests in foreign jurisdictions which could make it subject to foreign currency fluctuations and inflationary pressures which may adversely affect the Company’s financial position, results of operations and cash flows. The Company is affected by changes in exchange rates between the Canadian Dollar and foreign functional currencies. The Company does not invest in foreign currency contracts to mitigate the risks.

(b)

Credit risk

The Company’s cash and cash equivalents are held in a Canadian financial institution. The Company does not have any asset-backed commercial paper in its cash and cash equivalents or short-term investments. The Company’s amount receivable consists primarily of recovered rent and office expense, and tax due from the federal government of Canada.

(c)

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk through the management of its capital structure. Accounts payable and accrued liabilities are due within the current operating period.

(d)

Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The risk that the Company will realize a loss as a result of a decline in the fair value of the cash and cash equivalents is limited because they are generally held to maturity. A 1% change in the interest rate, with other variables unchanged, would affect the Company by an annualized amount of interest equal to approximately $1,000.

12.

MANAGEMENT OF CAPITAL RISK

The Company manages its cash and cash equivalents, common shares and stock options as capital (see Note 8). The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to pursue the development of its mineral and oil and gas properties and to maintain a flexible capital structure which optimizes the cost of capital at an acceptable risk.

The Company manages the capital structure and makes adjustments to it in light of changes in economic conditions and the risk characteristics of the underlying assets. To maintain or adjust the capital structure, the Company may attempt to issue new shares, issue new debt, acquire or dispose of assets or adjust the amount of cash and cash equivalents.

In order to facilitate the management of its capital requirements, the Company prepares expenditure budgets that are updated as necessary depending on various factors, including successful capital deployment and general industry conditions.

In order to maximize ongoing development efforts, the Company does not pay out dividends. The Company’s investment policy is to invest its short-term excess cash in highly liquid short-term interest-bearing investments with maturities 90 days or less from the original date of acquisition, selected with regards to the expected timing of expenditures from continuing operations.

The Company expects its current capital resources will be sufficient to carry its exploration plans and operations through its current operating period.

The Company operates in a single reportable operating segment, being exploration and development of mineral and oil and gas properties.

DIFFERENCES BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (GAAP)

Under Canadian GAAP for junior mining exploration companies, mineral exploration expenditures can be deferred on prospective mineral rights until such time as it is determined that further exploration work is not warranted, at which time the mineral right costs are written-off. Under U.S. GAAP, all exploration expenditures are expensed until an independent feasibility study has determined that the mineral rights are capable of economic commercial production. For oil and gas companies, under the successful efforts methodology, there are no differences under Canadian and U.S. GAAP. The Company has capitalized the costs of drilling exploratory wells pending determination of whether the well has found proven reserves. As no determination has yet been made, the costs remain capitalized for Canadian GAAP which is the identical treatment U.S. GAAP. The following items (a) to (g ) provide a summary of the impact to these financial statements that would result from the application of U.S. accounting principles to deferred mineral rights.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2010 AND 2009

This review of the Results of Operations should be read in conjunction with the unaudited Consolidated Financial Statements of the Company for the nine months ended March 31, 2010 and 2009.

For the three months ended March 31, 2010 the Company incurred a net loss of $340,865 ($0.01 per share) compared to a net loss of $5,372,537 ($0.18 per share) for the three months ended March 31, 2009. The decrease of $5,031,672 in the net loss for the period from 2009 to 2010 is primarily due to: (a)  the write-off of unproven mineral rights in the three months ending March 31, 2009 of $5,134,856 due to the sale of the Argentinean subsidiary; (b) a decrease in consulting and management fees of  $29,553 due to the cessation of operations in Argentina; (c) a decrease of salaries and benefits of $24,676 due to the cessation of operations in Argentina; (d) a decrease of accounting and audit fees of $15,466 due to the sale of the Argentinean subsidiary; and (e) a decrease in travel expenses of$ 15,230 due to the reduction of trips to Argentina; offset by an increase in project investigation expenses of $72,654; the increase of unrealized  losses on marketable se curities of $39,941; an increase in investor relation expenses of $23,909 and  a decrease in the  gain on sale of equipment of $18,466.

Expenses

General and administrative costs were $301,535 for the three months ended March 31, 2010, an increase of $32,821 as compared to $268,714 for the same period in the prior year.  The six largest expense items for this fiscal period, which account for 80% (2009 – 63%) of total general and administrative expenditures are: project investigation of $74,503 (2009 - $1,849), salaries and benefits of $69,675 (2009 - $94,351), office and miscellaneous expenses of $34,071 (2009 – $33,502), investor relations expense of $28,235 (2009 – $4,326), rent of $21,083 (2009 – 26,548) and stock based compensation expense of $14,475 (2009 – $7,578). The increase in project investigation expenses is due to the Company’s increased efforts to find new opportunities, the decrease in salaries and benefits is the result of the decrease in the number of salaried employees, as well as the sale of the Argentinean subsidiary. The decrease in office and miscellaneous exp enses is the result of the sale of the Argentinean subsidiary. The increase in investor relations expenses is due to an increase of trade show attendances and the promotion of a private placement. The decrease in rent is due to the recovery of rent due to the sub-lease of office space to other companies. The increase in stock based compensation expense is due to the vesting of officers’, consultants’ and employees’ stock options.

RESULTS OF OPERATIONS FOR THE NINE MONTHS ENDED MARCH 31, 2010 AND 2009

The decrease in the net loss for the period from 2009 to 2010 of $5,383,793 is primarily due to: (a) the write-off of unproven mineral rights in the same period in the prior year of $5,138,457 due to the sale of the Argentinean subsidiary; (b) a decrease in salaries and benefits of $319,348 due to a reduction of salaried staff and a compensation package paid to the former CEO of the Company in August 2008; (c) a decrease in investor relations expenses of $63,685 due to a reduced number of trade show attendances and a decrease in the cost of the Annual General Meeting material; (d) a decrease in travel expenses of $47,611 due to the reduction of trips to Argentina; and (e) a decrease of consulting and management fees of $42,032 due to the sale of the Argentinean subsidiary; off set by an increase in project investigation expenses of $115,564 due to the Company’s increased efforts to find new opportunities; an increase of stock based compensation of $77,650 due to the vesting of officers’, consultants’ and employees’ stock options; a decrease of interest income of $49,723 due to the decrease in the interest rates and lower cash amounts invested and a decrease of foreign exchange gain of  $33,261 due to the revaluation of the Canadian dollar.

Expenses

General and administrative costs were $817,126 for the nine months ended March 31, 2010, a decrease of $334,295 as compared to $1,151,421 for the same period in the prior year.  The six largest expense items for this fiscal period, which account for 79% (2009 – 74%) of total general and administrative expenditures were: project investigation of $172,002 (2009 - $56,438),salaries and benefits of $166,298 (2009 - $485,646), stock based compensation expense of $95,439 (2009 – $17,789), office and miscellaneous expenses of $84,813 (2009 – $113,639), rent of $69,397 (2009 – 66,776) and investor relations expense of $53,584 (2009 – $117,269). The increase in project investigation expenses is due to the Company’s increased efforts in finding new opportunities, the decrease in salaries and benefits is the result of the decrease in the number of salaried employees and a compensation package paid to the former CEO of the Company in August 2008, the increase in stock based compensation expense is due to the vesting of officers’, consultants’ and employees’ stock options. The decrease in office and miscellaneous expenses is the result of the sale of the Argentinean subsidiary. The increase in rent is a result of a decrease in the recovery charge for rent to related parties which moved out of the space. The decrease in investor relation expenses is due to a reduced number of trade show attendances and the decrease in the cost of the Annual General Meeting material.

•

29,651,539 common shares

•

3,683,600 common stock options with a weighted average exercise price of $0.28 expiring at various dates until March 6, 2015.

Commitments and Contingencies

RISK FACTORS

The Company’s financial success will be dependent upon the extent to which it can discover mineralization, oil and gas reserves or acquire mineral or oil and gas properties and the economic viability of developing its properties.

The Company competes with many companies possessing greater financial resources and technical facilities than itself.  The market price of minerals, metals and/or oil and gas is volatile and cannot be controlled. There is no assurance that the Company’s mineral exploration, oil and gas exploration and development activities will be successful. The development of mineral resources and oil and gas properties involves many risks that even a combination of experience, knowledge and careful evaluation may not be able to overcome.

The development of mineral and oil and gas resources in Mexico and Canada are subject to a comprehensive review, approval and permitting process that involves various federal and regional agencies.  There can be no assurance given that the required approvals and permits for a mining or oil and gas project, if technically and economically warranted, on the Company’s claims can be obtained in a timely or cost effective manner.

All of the Company’s short to medium term operating and cash flow must be derived from external financing.  Actual funding may vary from what is planned due to a number of factors including the progress of exploration and development on its current properties.  Should changes in equity market conditions prevent the Company from obtaining additional external financing, the Company will need to review its exploration and oil and gas property holdings to prioritise project expenditures based on funding availability.

The Company competes with larger and better financed companies for exploration personnel, contractors and equipment.  Increased exploration activity has increased the demand for equipment and services.  There can be no assurance that the Company can obtain required equipment and services in a timely or cost effective manner.

The Company’s operations in Mexico and Canada and financing activities in Canada make it subject to foreign currency fluctuations and such fluctuations may materially affect its financial position and results.

OUTLOOK

Portal has planned exploration programs for the oil and gas project in Central Alberta and it is continuing to review other mineral exploration projects for acquisition.

The recently opened office in Hermosillo, Sonora, Mexico, brings together the core corporate functions and management personnel released after the takeover of Nevada Pacific Gold by US Gold in late 2007. When combined with the directors of the Company this group has the collective experience and success of acquiring, developing and producing from three different open pit gold mines in Mexico over the last 17 years. Portal intends to leverage this knowledge and the business relationships built to acquire a portfolio of quality exploration projects.

•

The Company’s expectations regarding the ability to find new projects by its recently opened office in Mexico.

•

Expectations regarding the ability to raise capital to continue its exploration and project search programs.

•

INTERNAL CONTROLS AND PROCEDURES OVER FINANCIAL REPORTING

Changes in Internal Control Over Financial Reporting (“ICFR”)

No changes occurred in the current period of the Company’s ICFR that have materially affected or are reasonable likely to materially affect the Company’s ICFR.

INTERNATIONAL FINANCIAL REPORTING STANDARDS

On February 13, 2008, the Canadian Accounting Standards Board (“AcSB”) confirmed the mandatory changeover date to International Financial Reporting Standards (“IFRS”) for Canadian profit-oriented publicly accountable entities (“PAE’s”) such as the Company.

The AcSB requires that IFRS compliant financial statements be prepared for annual and interim financial statements commencing on or after January 1, 2011. For PAE’s with a June 30 year-end, the first unaudited interim financial statements under IFRS will be the quarter ending September 30, 2011, with comparative financial information for the quarter ended September 30, 2010. The first audited annual financial statements will be for the year ending June 30, 2012, with comparative financial information for the year ended June 30, 2011. This also means that all the opening balance sheet adjustments relating to the adoption of IFRS must be reflected in the July 1, 2010 opening balance sheet which will be issued as part of the comparative financial information in the September 30, 2011 unaudited interim financial statements.

The Company intends to adopt these requirements as set out by the AcSB and other regulatory bodies. At this time, the impact of adopting IFRS cannot be reasonably quantify areas relating to IFRS that could materially affect the Company. During the fiscal 2010, the Company will continue to evaluate the impact of IFRS on the Company, The actual conversion work will occur in 2010 and 2011, in anticipation of the preparation of the July 1, 2010 balance sheet that will be required for comparative purposes for all periods ending in fiscal 2012.

FINANCIAL INSTRUMENTS AND OTHER INSTRUMENTS

The fair values of the Company’s cash and cash equivalents, marketable securities, short-term investments, amounts receivable, accounts payables and accrued liabilities approximate their carrying values.

The Company’s financial instruments are exposed to certain financial risks, including currency risk, credit risk, liquidity risk and interest risk.

(a)

Currency risk

The Company may acquire property interests in foreign jurisdictions that may make it subject to foreign currency fluctuations and inflationary pressures which may adversely affect the Company’s financial position, results of operations and cash flows. The Company is affected by changes in exchange rates between the Canadian Dollar and foreign functional currencies. The Company does not invest in foreign currency contracts to mitigate the risks.

(b)

Credit risk

The Company’s cash and cash equivalents are held in a Canadian financial institution. The Company does not have any asset-backed commercial paper in its cash and cash equivalents or short-term investments. The Company’s amount receivable consists primarily of recovered rent and office expense, and tax due from the federal government of Canada.

(c)

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk through the management of its capital structure. Accounts payable and accrued liabilities are due within the current operating period.

(d)

Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The risk that the Company will realize a loss as a result of a decline in the fair value of the cash and cash equivalents is limited because they are generally held to maturity. A 1% change in the interest rate, with other variables unchanged, would affect the Company by an annualized amount of interest equal to approximately $1,000.

SUBSEQUENT EVENTS

On April 22, 2010 the Company announced that it has agreed to purchase a 6.6% “after pay-out” working interest (the “Interest)  in the Company’s Bigwave Oil and Gas Joint Venture (the “Joint Venture”) for a total of $5,000 in cash and 500,000 common shares in the capital of the Company.

The Participation Agreement was previously announced by the Company on April 14, 2009. The Agreement currently requires the Company to assign 30% of its 22% working interest in the Joint Venture (net 6.6%) to certain other participants in the Joint Venture after the Company recovers all if its invested capital from its share of oil and gas production revenue (after pay-out). On the closing of the purchase of the interest, the Participation Agreement will be terminated and Portal will hold a 22% working interest in the Joint Venture. The Company’s obligation to complete the purchase of the Interest is subject to the satisfaction of certain normal conditions precedent, including the completion of due diligence and receipts of any required approval from the TSX Venture Exchange.

On May 13, 2010, the Company announced it has decided not to proceed with a $1 million non-brokered private placement announced on January 26, 2010.

Subsequent to the end of the quarter the Company closed its office in Hermosillo, Sonora state, Mexico.
