In the opinion of management, the unaudited interim consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the financial position as of June 30, 2013, and the results of operations and cash flows for the period then ended. The financial data and other information disclosed in the notes to the interim consolidated financial statements related to this period are unaudited. The results for the three and six-month periods ended June 30, 2013 are not necessarily indicative of the results to be expected for any subsequent quarter or the entire year ending December 31, 2013. The unaudited interim consolidated financial statements have been condensed pursuant to the SEC’s rules and regulations and do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. Therefore, these unaudited interim consolidated financial statements should be read in conjunction with the Company’s annual audited consolidated financial statements and notes thereto for the year ended December 31, 2012, included in the Company’s Annual Report on Form 10-K/A filed on April 29, 2013 with the SEC.</p>

United States regulatory authorities require the Company to restore and reclaim its mine area after mining is completed. Pursuant to ASC 410,
<i>Asset Retirement and Environmental Obligations</i>
, the fair value of asset retirement obligation is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. Upon initial recognition of a liability, the fair value of the liability is expensed or added to the carrying amount of the associated asset and this additional carrying amount is depreciated over the life of the asset. Future reclamation and remediation costs are accrued based on management's best estimate at the end of each period of the costs expected to be incurred to remediate each project.

Estimated site restoration costs for exploration activities are accrued when incurred. Costs for environmental remediation are estimated each period by management based on current regulations, actual expenses incurred, available technology and industry standards. Any change in these estimates is included in mineral property expenditures during the period and the actual restoration expenditure incurred is charged to the accumulated asset retirement obligation provision as the restoration work is completed. At June 30, 2013 and December 31, 2012, the Company has recorded $39,000

Potential benefits of income tax losses are not recognized in the accounts until realization is more likely than not. The Company has adopted ASC 740,
