Exhibit 99.2

INDEPENDENT AUDITORS' REPORT

To the Stockholders of

  Sociedad de Servicios Técnicos Geológicos Geotec Boyles Bros S.A.

We have audited the accompanying balance sheets of Sociedad de Servicios Técnicos Geológicos Geotec Boyles Bros S.A. (the "Company") as of December 31, 2011 and the related statements of income, stockholders' equity, and cash flows for the years ended December 31, 2011 and 2009. These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America.  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting.  Accordingly, we express no such opinion.  An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2011 and 2009 and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS

(In thousands of United States dollars - ThUS$)

(The 2010 financial statements are unaudited)

Note 1. Description of business

The Company provides mining prospection services principally in the area of drilling and maintenance and recovery of water wells.

Note 2. Summary of significant accounting policies

Basis of Presentation - The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America.

Foreign Currency Transactions and Translation - The currency of the country in which the Company is incorporated is the Chilean pesos.  Management determined the U.S. dollar as the Company’s functional currency in accordance with the Statement of Financial Accounting Standards (“SFAS”) No. 52 (codified in FASB ASC Topic 830).  Accordingly, the Company remeasured into U.S. dollars monetary assets and liabilities at year-end exchange rates while nonmonetary items are remeasured at historical rates. Income and expense accounts are remeasured at the average rates in effect during the year, except for depreciation which is remeasured at historical rates.  Gains or losses from changes in exchange rates are recognized in income in the year of occurrence. Foreign exchange gains (losses) for 2011, 2010 and 2009 amounted toThUS$(3,304), ThUS$822 and ThUS$(144), respectively.

Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Inventories - Inventories are valued at the lower of cost or market (net realizable value). Cost is determined by the weighted average method. Allowances are recorded for inventory considered to be excess or obsolete.  The amount of allowance for inventory reserve as of December 31, 2011 and 2010 was ThUS$533 and ThUS$423, respectively.

Property, plant and equipment - Property, plant and equipment are recorded at acquisition cost, net of accumulated depreciation. Routine maintenance cost are expense as incurred.  Assets acquired under capital leases are recorded as acquisitions of property, plant and equipment, in an amount equivalent to the lower of; present value of the minimum lease payments, plus the present value of the purchase option and market value.  The assets will be legally owned by the company only when it exercises the purchase option.

1

Depreciation is provided using the straight-line method over the estimated useful lives of the assets. Depreciation expense for assets owned was ThUS$6,664, ThUS$5,395 and ThUS$4,564 in 2011, 2010 and 2009, respectively.  Depreciation expense for leased assets was ThUS$4,061, ThUS$3,629 and ThUS$3,245 in 2011, 2010 and 2009, respectively.  The useful lives used for the items within each property classification are as follows:

	Years
Buildings	20
Camps	1
Machinery and equipment	5
Vehicles	3 to 5
Leased assets	5

Impairment of Long-Lived Assets - Long-lived assets, such as property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset.  If the carrying amount of an asset exceeds its estimated future cash flows, then an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.  The Company has determined that no impairment of long-lived assets was required, as of December 31, 2011 and 2010.

Revenue recognition- Revenues from contracts for the Company’s mineral exploration drilling services are billable based on the quantity of drilling performed. Thus, revenues for these drilling contracts are recognized on the basis of actual footage or meterage drilled. Revenues from contracts for maintenance and recovery of water wells are recognized upon rendering of such services.

Allowance for doubtful accounts receivables - The Company estimates the allowance based on an individual analysis of customer credit worthiness and payment capacity.  The Company has determined that no allowance for doubtful accounts receivables was required, as of December 31, 2011 and 2010.

Cash and cash equivalents - The Company considers investments with an original maturity of three months or less when purchased to be cash equivalents.  As of December 31, 2011 and 2010, cash and cash equivalent include cash on hand and in banks.  The carrying value of cash and cash equivalents approximates fair value.

Accrued expenses - Vacation cost and compensation plan for executives accruals are accrued as an expense in the year in which earned.

Income taxes - Income taxes are provided using the asset-and-liability method, in which deferred taxes are recognized for the tax consequences of temporary differences between the financial statement carrying amounts and tax bases of existing assets and liabilities.  Deferred tax assets are reviewed for recoverability and valuation allowances are provided as necessary. Provisions for income taxes are made in accordance with Chilean tax regulations.

2

The Company’s estimate of uncertainty in income taxes is based on the framework established in the accounting for income taxes guidance. This guidance addresses the determination of how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. For tax positions that meet this recognition threshold, the Company applies judgment, taking into account applicable tax laws and experience in managing tax audits and relevant GAAP, to determine the amount of tax benefits to recognize in the financial statements. For each position, the difference between the benefit realized on our tax return and the benefit reflected in the financial statements is recorded as a liability in the consolidated balance sheet. This liability is updated at each financial statement date to reflect the impacts of audit settlements and other resolution of audit issues, expiration of statutes of limitation, developments in tax law and ongoing discussions with taxing authorities. As of December 31, 2011 and 2010 there are no uncertain tax positions that should be recorded in the financial statements. In addition, the Company does not have any accrued interest and penalties related to unrecognized tax benefits.

Investment in affiliated companies - Investments in affiliates (20% to 50% owned) in which the Company has the ability to exercise significant influence over operating and financial policies are accounted for by the equity method.

Fair Value of Financial Instruments - The carrying amounts of financial instruments, including cash and cash equivalents, trade and note receivables, accounts and notes payable and accrued expenses approximate fair value as of December 31, 2011 and 2010, because of the relatively short maturity of those instruments. See Note 7 for disclosure regarding the fair value of indebtedness of the Company.

Note 13. Subsequent events

Between January 1st, 2012 and March 7, 2012, the issuance date of these financial statements, no subsequent events occurred that could materially affect the financial results of the Company.

Note 14. New accounting pronouncements

In May 2011, the Financial Accounting Standards Board, or FASB, issued a FASB ASU 2011-04 – Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. ASU 2011-04 clarifies the application of certain existing fair value measurement guidance and expands the disclosures for fair value measurements that are estimated using significant unobservable (Level 3) inputs. This new guidance is effective on a prospective basis for annual and interim reporting periods beginning on or after December 15, 2011. We do not expect that adoption of this new standard will have a material impact on our consolidated financial statements.
