Revenue, Deferred Revenue and Related Costs	18.Revenue, Deferred Revenue and Related Costs Oxide Plant Lease and Oxide Plant Lease Costs For the year ended December 31, 2019 the Company recorded revenue of approximately $7.7 million and related costs of approximately $2.4 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 Consolidated Statements of Operations following the guidance of ASC 842. ASC 842 supports recording as gross revenue the reimbursement of expenses incurred directly by the Company in performing its obligations under the lease in situations where the entity has control over the specific goods or services transferred to a customer as a principal versus as an agent. The actual costs incurred for reimbursed direct labor and utility costs are reported as “Oxide plant lease costs” in the Consolidated Statements of Operations. The Company recognizes lease fees during the period the fees are earned per the terms of the lease. The oxide plant lease revenue includes a minimum fixed fee of $125,000 per month that is not dependent on tonnes processed. The monthly fixed fee remains payable for as long as the lease is in effect. 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. (“Hecla”), 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 fixed fees and throughput related charges remained 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. The Company will recognize the $1.0 million of income from granting the option over the expected life of the lease through December 31, 2020 on a straight-line basis, including such income in “Revenue: Oxide plant lease” in the Consolidated Statements of Operations and Comprehensive Loss. During each of the years ended December 31, 2019 and 2018, the company recognized approximately $0.3 million of amortized income related to the upfront cash payment, included in “Revenue: Oxide plant lease” in the Consolidated Statements of Operations and Comprehensive Loss. As of December 31, 2019, the unamortized portion of the lease option totaled approximately $0.3 million recorded as short term “Deferred revenue” on the Consolidated Balance Sheets. On December 2, 2019 the Company and Hecla entered into a Third Amendment to the Master Agreement and Lease Agreement dated August 2, 2017. Under the terms of the Third Amendment, the Company has agreed to reduce the per tonne fee payable by Hecla for the duration of the lease term, commencing on January 1, 2020 from $22.00 per tonne to $11.00 per tonne. However, the Company will receive $22.00 per tonne processed during any month in which one of the following conditions occur: (1) the Comex daily silver spot closing average price for such month is equal to or greater than $20.00 per ounce, or (2) the mill head grade average from the metallurgical balance for such month is equal to or greater than 1,000 grams per ton equivalent silver head grade. If either of the conditions are met in any month, Hecla will pay the $22.00 fee on all amounts processed in the oxide plant during such month. The reduced fee only applies to the tonnage-based payments under the Lease Agreement; the monthly lease payment of $125,000 per month is not affected by the Third Amendment. Under the terms of the Lease Agreement, Hecla had the right to terminate the Lease Agreement at any time upon 120 days written notice. The Third Amendment extended the advance notice required to 150 days. The Company has determined that the ability to receive the higher $22.00 per tonne fee, as described above, creates a derivative asset. The Company treated the derivative asset as an upfront lease payment that will be amortized over the remaining life of the lease and also recorded deferred revenue equal to the value of the derivative asset, as more fully described in Note 9. The amortization of the upfront lease payment and the increase in the derivative asset at December 31, 2019 were recorded as an increase of approximately $74,000 to “Revenue: Oxide plant lease” in the Consolidated Statements of Operations for the period ended December 31, 2019. Hecla has 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. For the year ended December 31, 2018 the Company recorded revenue of approximately $7.2 million and related costs of approximately $2.3 million associated with the lease of the Velardeña Properties oxide plant. .
