The Company is a Nevada corporation and is subject to federal income taxes. Nevada does not impose a corporate income tax.

Significant components of the Company’s net deferred income tax assets and liabilities were as follows at:

A valuation allowance was established for net deferred tax assets due to the uncertainty of realizing these deferred tax assets based on conditions existing at December 31, 2016 and 2015, respectively.

The realizability of deferred tax assets are reviewed at each balance sheet date. The majority of the Company’s deferred tax liabilities are depletable. Such depletion will begin with the processing of mineralized material once production has commenced. Therefore, the deferred tax liabilities will reverse in similar time periods as the deferred tax assets. The Company assesses both positive and negative evidence to determine whether it is more likely than not that such reversal will occur to realize the deferred tax assets prior to their expiration.

The acquisition related liabilities are a result of the estimated future federal income tax liability associated with the temporary difference between the acquisition consideration and the tax basis. The deferred tax liabilities were reflected as an increase to the total purchase price which has been applied to the underlying mineral and Columbus project assets in the absence of there being a goodwill component associated with the acquisition transactions.

A reconciliation of the tax provision at U.S. federal tax rates to the actual tax provision recorded in the financial statements consisted of the following components for the years ended:

The Company had cumulative net operating losses of approximately $41,445,072 as of December 31, 2016 for federal income tax purposes. Cumulative net operating losses from December 31, 2006 and previous years are effectively nil due to the annual limitation imposed by the Internal Revenue Code of 1986 as a result of the ownership percentage change limitations. The net operating loss carryforwards will expire between 2027 and 2036.

The Company and its subsidiary file income tax returns in the United States. These tax returns are subject to examination by taxation authorities provided the years remain open under the relevant statutes of limitations, which may result in the payment of income taxes and/or a decrease in the net operating losses available for carryforwards. The Company has losses from inception to date, and thus all years remain open for examination. While the Company believes that its tax filings do not include uncertain tax positions, the results of potential examinations or the effect of changes in tax law cannot be ascertained at this time. The Company currently has no tax years under examination.
