Subsequent Event	21. Subsequent Event 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 (the “Consideration Shares”), 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 must exercise the option to extend the lease no later than October 3, 2018. 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 will have 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 we decide to use the oxide plant for our own purposes before December 31, 2020. The Consideration Shares were offered and sold without registration under the Securities Act of 1933, as amended (the “Act”) in reliance on the exemptions provided by Section 4(a)(2) of the Act and/or Regulation D promulgated thereunder. Under the terms of the Option Agreement, the Company agreed to register with the SEC the resale of the Consideration Shares. The agreement requires that the Company use its commercially reasonable efforts to file a registration statement with the SEC and have it declared effective no later than six months from the date of issuance of the Consideration Shares. The Company expects to 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 Operation and Comprehensive Loss. The $1.0 million received for the Consideration Shares, net of any direct charges, will be recorded as equity in the Condensed Consolidated Balance Sheets for the quarter ended September 30, 2017.
