Revenue, Deferred Revenue and Related Costs	15. Revenue, Deferred Revenue and Related Costs Oxide Plant Lease and Oxide Plant Lease Costs For the nine months ended September 30, 2018 the Company recorded revenue of approximately $5.3 million and related costs of approximately $1.7 million associated with the lease of the Velardeña Properties oxide plant. The Company recognizes oxide plant lease fees and reimbursements for labor, utility and other costs as “Revenue: Oxide plant lease” in the Condensed Consolidated Statements of Operations and Comprehensive Loss following the guidance of ASC 606 regarding the income statement characterization of reimbursements received for certain expenses incurred by the Company in performing its obligations under the lease and reporting revenue gross as a principal versus net as an agent. ASC 606 supports recording as gross revenue fees received for the reimbursement of expenses in situations where the recipient is the primary obligor and has certain discretion in the incurrence of the reimbursable expense. The actual costs incurred for reimbursed direct labor and utility costs are reported as “Oxide plant lease costs” in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company recognizes lease fees during the period the fees are earned per the terms of the lease. On August 2, 2017, the Company granted Hecla an option to extend the oxide plant lease for an additional period of up to two years ending no later than December 31, 2020 (the “Extension Period”) in exchange for a $1.0 million upfront cash payment and the purchase of $1.0 million, or approximately 1.8 million shares, of the Company’s common stock, issued at par at a price of $0.55 per share, based on an undiscounted 30-day volume weighted average stock price. The option and lease extension were memorialized in (i) an Option Agreement dated August 2, 2017 among the Company and Hecla Mining Company (the “Option Agreement”), and (ii) a Second Amendment to Master Agreement and Lease Agreement dated August 2, 2017 among Minera William S.A. de C.V., an indirect subsidiary of the Company, and Minera Hecla S.A. de C.V., an indirect subsidiary of Hecla Mining Company (the “Second Amendment”). Under the Second Amendment, Hecla had an option to extend the lease to December 31, 2020 by exercising the option no later than October 3, 2018. On October 1, 2018 Hecla exercised the Second Amendment option and extended the lease to December 31, 2020. All of the fixed fees and throughput related charges remain the same as under the original lease. Similar volume limitations apply to any required future tailings expansions, which Hecla will fund, leaving unused at the end of the lease term an agreed amount of capacity in the expanded tailings facility. Pursuant to the Second Amendment, Hecla has the right to terminate the lease during the Extension Period for any reason with 120 days’ notice. Hecla will also have a one-time right of first refusal to continue to lease the plant following a termination notice through December 31, 2020 if the Company decides to use the oxide plant for its own purposes before December 31, 2020. The Company will recognize the $1.0 million of income from granting the option over the expected life of the lease from August 2, 2017 through December 31, 2020 on a straight-line basis, including such income in “Other operating income” in the Condensed Consolidated Statements of Operations and Comprehensive Loss. During the nine months ended September 30, 2018 the company recognized approximately $0.3 million of amortized income related to the upfront cash payment. As of September 30, 2018, the unamortized portion of the lease option totaled approximately $0.7 million recorded as short and long term “Deferred revenue” on the Condensed Consolidated Balance Sheets. For the nine months ended September 30, 2017 the Company recorded revenue of approximately $5.1 million and related costs of approximately $1.7 million associated with the lease of the Velardeña Properties oxide plant.
