REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors

Casablanca Mining Ltd.

We have audited the accompanying balance sheets of Casablanca Mining Ltd. (an exploration stage company) (formerly USD Energy Corp.), as of December 31, 2010 and 2009 and the related statements of operations, stockholders' equity (deficit) and cash flows for each of the periods then ended and for the period from June 27, 2008 (inception) through December 31, 2010. 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 audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included 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 includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Casablanca Mining Ltd. as of December 31, 2010 and 2009 and the related statements of operations, stockholders' equity (deficit) and cash flows for each of the periods then ended and the period from June 27, 2008 (inception) through December 31, 2010 in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements the Company has suffered losses from operations and has no sources of revenue that raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Exhibit 99.1

Casablanca Mining Ltd.

(An Exploration Stage Company)

Notes to Audited Financial Statements

For the period June 27, 2008 (Inception) through December 31, 2010

NOTE 1:     ORGANIZATION

Casablanca Mining Ltd. was incorporated as USD Energy Corp. (the “Company,” “Casablanca” or “we”) on June 27, 2008 in the State of Nevada.  On December 31, 2010, the Company completed the exchange of 25,500,000 shares of its Common Stock for all of the issued and outstanding capital shares of Santa Teresa Minerals, S.A., a limited liability company organized under the laws of Chile (“Santa Teresa Minerals”).   On February 4, 2011, the Company filed an amendment to its Articles of Incorporation with the Nevada Secretary of State to change its name from USD Energy Corp. to Casablanca Mining Ltd.  

The Company has a plan of operations to engage in the business of the acquisition, exploration, development, and operation of precious metals properties.  The Company is an “exploration stage company” as defined in the Accounting Standards Codification Topic No. 915 “Development Stage Entities” (ASC 915).  The Company has devoted its resources to establishing the new business, and as the acquisition of Santa Teresa Minerals was not completed until December 31, 2010, planned operations had not yet commenced during the periods covered by these financial statements.  Accordingly, no revenues have been earned during the period from June 27, 2008 (date of inception) to December 31, 2010.

In the opinion of management, all adjustments (consisting only of normal recurring adjustments) which are necessary to provide a fair presentation of operating results for the interim period presented have been made.  The results of operations for the periods presented are not necessarily indicative of the results to be expected for the year.

The Company’s accounting and reporting policies conform to U.S. GAAP applicable to exploration stage enterprises.

The functional currency of Casablanca is the United States Dollar, the functional currency of its subsidiary Santa Teresa Minerals is Chilean Pesos.  The financial statements are presented in United States dollars.

NOTE 2:                      GOING CONCERN

The Company’s financial statements at December 31, 2010 and for the period June 27, 2008 (inception) through December 31, 2010 have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities and commitments in the normal course of business.  The Company has incurred a loss of $79,950 through December 31, 2010.  In addition, the Company has not generated any revenues.  These conditions raise substantial doubt as to the Company’s ability to continue as a going concern.

The Company may not be able to obtain additional funds that it may require.  The Company does not presently have adequate cash from operations to meet its long-term needs.  The Company does not currently have any established third-party bank credit arrangements.  The Company will seek additional funds through equity or debt financings, if available on terms and schedules acceptable to the Company.   If the additional funds that the Company may require are not available to it, the Company may be required to curtail significantly or eliminate some or all of its development programs.

These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

Exhibit 99.1

NOTE 3:                      SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

For purposes of the statement of cash flows, the Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Mining Properties and Equipment

The Company will follow the successful efforts method of accounting.  All developmental costs will be capitalized.  The Company is predominately engaged in the acquisition and development of proved reserves as opposed to exploration activities.  Depreciation and depletion of producing properties will be computed on the unit-of-production method based on estimated proved reserves. Repairs and maintenance will be expensed, while renewals and betterments will be generally capitalized.

At least quarterly, or more frequently if conditions indicate that long-term assets may be impaired, the carrying value of our properties will be compared to management's future estimated pre-tax cash flow from the properties. If undiscounted cash flows are less than the carrying value, then the asset value will be written down to fair value. Impairment of individually significant unproved properties will be assessed on a property-by-property basis, and impairment of other unproved properties is assessed and amortized on an aggregate basis.

Asset Retirement Obligation

The Company’s financial statements will reflect the fair value for any asset retirement obligation, consisting of future plugging and abandonment expenditures related to our properties, which can be reasonably estimated. The asset retirement obligation will be recorded as a liability at its estimated present value at the asset's inception, with an offsetting increase to producing properties on the balance sheet. Periodic accretion of the discount of the estimated liability will be recorded as an expense in the statements of operations.

Stock Based Compensation

The Company records stock based compensation in accordance with the guidance in ASC Topic 505 and 718 which requires the Company to recognize expense related to the fair value of its employee stock option awards.  This eliminates accounting for share-based compensation transactions using the intrinsic value and requires instead that such transactions be accounted for using a fair-value-based method. The Company recognizes the cost of all share-based awards on a graded vesting basis over the vesting period of the award..

Estimates

The presentation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures 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 these estimates.

Fair Value of Financial Instruments

The carrying amounts for the Company’s cash and related party payables approximate fair value due to the short-term maturity of these instruments.

7

Exhibit 99.1

Income Taxes

Accounting Standards Codification Topic No. 740 “Income Taxes” (ASC 740) requires the asset and liability method of accounting be used for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Earnings (Loss) Per Share

Per Accounting Standards Codification Topic 260 “Earnings Per Share” (ASC 260), basic EPS is determined using net income divided by the weighted average shares outstanding during the period. Diluted EPS is computed by dividing net income by the weighted average shares outstanding, assuming all dilutive potential common shares were issued.

NOTE 4:                      SANTA TERESA ACQUISITION

On December 31, 2010, the Company completed the exchange of 25,500,000 shares of its Common Stock, par value $.001 per share (“Common Stock”), valued at $.05 per share, for all of the issued and outstanding capital shares of Santa Teresa Minerals, pursuant to that certain Exchange Agreement (the “Exchange Agreement”), dated December 7, 2010, among the Company, Santa Teresa Minerals, and its shareholders, Juan Carlos Camus Villegas, Don Felipe Igancio Jimenez Gonzalez, Carolina Constanza Camus Gonzalez, Angelica Soledad Camus Gonzalez and Angelica Elisa Gonzalez Gonzalez (collectively, the “Santa Teresa Shareholders”).  The value of our shares of Common Stock was determined by a third party valuation. The Exchange Agreement was described in greater detail in our Current Report on Form 8-K filed December 13, 2010.

Before the Exchange Agreement, we had no previous relationship with Santa Teresa Minerals or any of the Santa Teresa Shareholders, except that Thomas Ronk, who immediately prior to the transaction that took place on December 31, 2010, beneficially owned 27% of our Common Stock, is the brother-in-law of Juan Carlos Camus Villegas.

Concurrent with the execution of the Exchange Agreement, we also entered into a Convertible Debt Agreement, whereby we assumed all existing debt of Santa Teresa Minerals, consisting of $1,087,000, owed to Juan Carlos Camus Villegas, a Santa Teresa Shareholder, and agreed to grant Mr. Villegas a convertible promissory note (the “Villegas Note”) for the amount of such debt.

Concurrent with the execution of the Acquisition Agreement, certain USD Principal Shareholders and the Santa Teresa Shareholders entered into a Shareholders Agreement, which grants the Santa Teresa Shareholders “drag along rights” to require the USD Shareholders to participate, on the same terms and conditions, in any change of control involving a sale of the Common Stock by the Santa Teresa Shareholders, and the USD Principal Shareholders “tag along rights” to participate, on the same terms and conditions, in any change of control involving a sale of the Common Stock by the Santa Teresa Shareholders, except such a sale to any affiliates of the selling shareholder.

We have reviewed our acquisition of Santa Teresa Minerals to determine the proper accounting for this transaction  in accordance with Accounting Standards Codification 805 – “Business Combinations” (ASC 805).  Based on our review of ASC 805-10-55-11 and ASC 805-10-55-12, we have determined that the acquisition should be treated as a purchase. The assets we acquired through Santa Teresa Minerals included principally: cash, accounts receivable, fixed assets (recorded at fair value) including land and mining equipment; and liabilities acquired consisted of accounts payable and notes and loans payable.   The difference between the value of the shares issued in consideration and the assets less liabilities was recorded as Goodwill.

NOTE 7:                      DEBT

During the period ended December 31, 2008, Ms. Malone paid $5,000 on the Company’s behalf for legal fees.This was recorded as an interest free loan due to a related party. The loan is due to Ms. Malone upon receipt of funds from a stock offering or other fundraising.The balance due on this loan at December 31, 2010 is $5,000.

On February 7, 2009, the Company issued a Convertible Note (the “Note”) to Suprafin, Ltd. in exchange for Suprafin’s agreement to lend the Company up to $25,000 for operating expenses.The Note bears an interest rate of 10.0% per annum and initially provided for payment in full on February 7, 2010.

9

Exhibit 99.1

Unpaid principal and interest under the Note were convertible at any time at the holder’s option into shares of the Company’s Common Stock at the market closing price on the day prior to conversion.On February 5, 2010, the Note was amended to extend the maturity date to February 7, 2011, to increase the amount the Company may borrow to up to $50,000, and to set the conversion price at $.0225 per share.

On July 27, 2010, Suprafin elected to convert the$45,312of then outstanding principal and interest under the Note into 2,013,867 shares of the Company’s Common Stock.During the three months ended December 31, 2010, Suprafin paid $8,650 on the Company’s behalf for legal and accounting fees, and the Company treated such payment as funds borrowed under the Note.At December 31, 2010, the principal balance due on the Note was $14,150, and accrued interest on the Note at December 31, 2010 was $338.

Concurrent with the execution of the Exchange Agreement, we also entered into a Convertible Debt Agreement, whereby we assumed all existing debt of Santa Teresa Minerals owed to Juan Carlos Camus Villegas, a Santa Teresa Shareholder, and agreed to grant Mr. Villegas a convertible promissory note (the “Villegas Note”) for, $1,087,000, the amount of such debt.

10

Exhibit 99.1

The Villegas Note will bear no interest and is payable in full, unless earlier converted, on November 1, 2012.Mr. Villegas may declare the Villegas Note immediately due and payable in the event of any material breach of the Villegas Note that remains uncured for 30 days, commencement of proceedings under bankruptcy, the Company’s dissolution, or attachment against a material portion of the Company’s assets.The Villegas Note is convertible during a period of 18 months following the closing of the Acquisition into (a) Common Stock at the conversion price of $0.01 per share of Common Stock, subject to certain adjustments in the event of merger, recapitalization or future capital stock issuances, or (b) in the event the Company issues any capital stock other than Common Stock, such new class or series of capital stock at a per share price equal to the lowest per share price at which such shares of new capital stock are issued.Such conversion right is limited so that Mr. Villegas may not convert the Villegas Note to the extent such conversion would result in the Santa Teresa Shareholders collectively holding, in the aggregate, more than 51% of the outstanding Common Stock of the Company.We have evaluated the beneficial conversion feature of this note as of December 31, 2010 and deemed it to be immaterial.We will re-evaluate this determination quarterly.

Santa Teresa Minerals also had the following outstanding notes and loans as of December 31, 2010, intercompany transactions have been eliminated in the consolidated balance sheets:

On July 14, 2009, the Company effected a 1 for 30 forward split of its Common Stock and has been applied on a retroactive basis.

NOTE 11:                      NEW ACCOUNTING PRONOUNCEMENTS

In January 2010, FASB issued ASU No. 2010-06 – Improving Disclosures about Fair Value Measurements. This update provides amendments to Subtopic 820-10 that requires new disclosure as follows: 1) Transfers in and out of Levels 1 and 2. A reporting entity should disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers. 2) Activity in Level 3 fair value measurements. In the reconciliation for fair value measurements using significant unobservable inputs (Level 3), a reporting entity should present separately information about purchases, sales, issuances, and settlements (that is, on a gross basis rather than as one net number). This update provides amendments to Subtopic 820-10 that clarifies existing disclosures as follows: 1) Level of disaggregation. A reporting entity should provide fair value measurement disclosures for each class of assets and liabilities. A class is often a subset of assets or liabilities within a line item in the statement of financial position. A reporting entity needs to use judgment in determining the appropriate classes of assets and liabilities. 2) Disclosures about inputs and valuation techniques. A reporting entity should provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements. Those disclosures are required for fair value measurements that fall in either Level 2 or Level 3. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll forward of activity in Level 3 fair value measurements. Thos disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. The Company is currently evaluating the impact of this ASU; however, we do not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

ASU 2010-28, Intangibles – Goodwill and Other (Topic 350) - When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts - a consensus of the FASB Emerging Issues Task Force This ASU modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. The Company is currently evaluating the impact of this ASU; however, we do not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

ASU 2010-29, Business Combinations (Topic 805) - Disclosure of Supplementary Pro Forma Information for Business Combinations - a consensus of the FASB Emerging Issues Task Force This ASU specifies that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The ASU also expands the supplemental pro forma disclosures under ASC Topic 805. The amendments are effective prospectively for business combinations for which the acquisition date is on or after December 15, 2010. The Company is currently evaluating the impact of this ASU; however, we do not expect the adoption of this ASU to have a material impact on our consolidated financial statements.
