Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America. This responsibility includes the design, implementation and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

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 from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor's judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the Company’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. Accordingly, we express no such opinion. An audit also includes assessing the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made ​​by the Company’s management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2012 and 2011, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Other Matter

The accompanying statements of income and cash flows for the year ended December 31, 2010 were not audited, reviewed, or compiled by us and, accordingly, we do not express an opinion or any other form of assurance on them.

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 monthly 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 2012, 2011 and 2010 amounted to ThUS$1,520, ThUS$(3,304) and ThUS$822, 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. Adjustments of value are recorded for inventory considered to be excess or obsolete.  The amount of adjustments as of December 31, 2012 and 2011 was ThUS$603 and ThUS$533, respectively.

Property, plant and equipment - Property, plant and equipment are recorded at acquisition cost, net of accumulated depreciation. Routine maintenance costs 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. As of December 31,2012, accumulated depreciation for assets owned and for leased assets amounted ThUS$53,717 and ThUS$880, respectively, (ThUS$47,918 and ThUS$1,701, as of December 31, 2011, respectively). Depreciation expense for assets owned was ThUS$12,958, ThUS$9,586 and ThUS$7,963 in 2012, 2011 and 2010, respectively.  Depreciation expense for leased assets was ThUS$715, ThUS$1,139 and ThUS$1,061 in 2012, 2011 and 2010, 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, for the years ended December 31, 2012 and 2011.

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, 2012 and 2011.

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, 2012 and 2011, cash and cash equivalents include cash on hand and in banks, and marketable securities.  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.

2

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 statements carrying amounts and tax basis 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.

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 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, 2012 and 2011 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, 2012 and 2011, because of the relatively short maturity of those instruments. See Note 6 and 9, for disclosures regarding the fair value of mutual funds and indebtedness of the Company, respectively.

Note 6. Fair Value Measurements

The Company’s estimates of fair value for financial assets and liabilities are based on the framework established in the fair value accounting guidance. The framework in based on the inputs used in the valuation, gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available. The three levels of inputs used to measure fair value are listed below:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than those included in Level 1, such as quoted market prices for similar assets and liabilities in active markets or quoted prices for identical assets in inactive markets.

Level 3 – Unobservable inputs reflecting our own assumptions and best estimate of what inputs market participants would use in pricing an asset or liability.

The Company’s assessment of the significance of a particular input to the fair value in its entirety requires judgment and considers factors specific to the asset or liability. The Company’s financial instruments held at fair value are presented below as of December 31, 2012:

Financial assets held at fair value	Carrying		Fair value measurements
