Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of Estimates In preparing financial statements in conformity with generally accepted accounting principles, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenditures during the reported periods. Actual results could differ materially from those estimates. Estimates may include those pertaining to valuation of inventories, stockpiles and mineralized material on leach pads, the estimated useful lives and valuation of plant and equipment, mineral rights, deferred tax assets, derivative assets and liabilities, reclamation liabilities, stock-based compensation and payments, and contingent liabilities.
Income Taxes	Income Taxes We recognize deferred tax assets and liabilities based on differences between the consolidated financial statement carrying amounts and tax bases of certain recorded assets and liabilities and for tax loss carryforwards. Realization of deferred tax assets is dependent upon our ability to generate sufficient future taxable earnings. Where it is more likely than not that the deferred tax asset will not be realized, we have provided a full valuation allowance.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Compensation - Stock Compensation (Topic 718). This standard is intended to simplify the accounting for several aspects of the accounting for equity-based compensation, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016 and early adoption is permitted. The Company is currently evaluating the effect that adopting this new accounting guidance will have on its consolidated results of operations and financial position. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 affects any entity that enters into a lease, with some specified scope exceptions. For public business entities, the amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. Early application is permitted for all entities. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements, which will require right of use assets and lease liabilities be recorded in the consolidated balance sheet for operating leases. In May 2014, the FASB issued ASU 2014-09, which introduces a new five-step revenue recognition model in which an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This standard was originally effective for fiscal years beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers, which defers the effective date of ASU 2014-09 for all entities by one year to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing, which is an amendment that clarifies the following two aspects of the new five-step revenue recognition model: identifying performance obligations and the licensing implementation guidance. The effective date and transition requirements for the amendments in this update are the same as ASU 2015-014. The Company is currently evaluating the new guidance to determine the impact it will have on its consolidated financial statements.
