Golden Minerals Company ("Golden Minerals", "Golden" or "the Company") announces that Minera Hecla S.A. de C.V. ("Hecla") has exercised its right to extend the lease of Golden's oxide mill in Durango State, Mexico for an additional 18 months, through December 31, 2018. Additionally, Golden announces its filing of the National Instrument 43-101 ("NI 43-101") compliant mineral resource estimate for the Santa Maria silver and gold project, under slightly amended terms from those announced in February 2017.
Oxide Mill Lease
Golden leased its then-vacant oxide mill to Minera Hecla S.A. de C.V., a wholly-owned subsidiary of Hecla Mining Company, in July 2015 for an initial period of 18 months. The lease agreement contained several lease extension options, and in the third quarter 2016 the lease was extended through June 2017. The 2016 extension included an agreement under which Hecla would construct, at its cost, certain tailings expansion facilities to accommodate Hecla's increased use of tailings capacity. On March 24, 2017, Golden was notified of Hecla's exercise of its option to extend the lease term through December 31, 2018. Tailings expansion work began earlier this year and is expected to be completed in April 2017. This lease has provided a source of revenue to the Company during a period in which Golden has not had active mining operations at its own properties. The lease provided approximately $4.4 million in net cash flow to the Company in 2016, and at Hecla's anticipated average 400 tonnes per day production rate, Golden anticipates net cash of approximately $0.4 million per month or $4.8 million annually, in 2017.
Santa Maria Mineral Resource Estimate and PEA Dated March 30, 2017
On March 31, 2017, Golden Minerals intends to file on SEDAR the NI 43-101 compliant resource estimate and related Preliminary Economic Assessment ("PEA") announced in February 2017, under slightly amended terms from those previously communicated. Due to an adjustment in the precise location of the claim, the updated property position results in an approximate 25 percent reduction to the previously announced inferred resource estimate, from a reported 160,000 tonnes to approximately 120,000 tonnes. Indicated resources are not affected by the adjustment and remain the same as previously communicated. The resource adjustment reduces the net present value of the project under the PEA by less than three percent, from $6.4 million to $6.3 million. The adjustment has not changed the Company's belief that there is excellent potential for expansion of the Santa Maria project, and that such expansion could lead to production beyond the initial three-year period considered in the PEA. Work continues at Santa Maria in support of potential expansion.
Santa Maria Mineral Resource Estimate Dated March 30, 2017
In conjunction with the PEA, the independent firm of Tetra Tech prepared an updated NI 43-101 compliant mineral resource estimate. Indicated and inferred mineral resource estimates as of March 30, 2017 are shown as follows:

PEA Information
The discounted cash flows in the PEA are provided post-tax and the PEA and updated resource is in compliance with NI 43-101 requirements. Tetra Tech is an independent engineering firm that served as principal author of the PEA prepared on behalf of the Company. Geoff Elson, PG is the independent Qualified Person from Tetra Tech who reviewed and approved the portions of this press release regarding mineral resources. Mark Horan, P.Eng of Tetra Tech is the independent Qualified Person who has reviewed and approved the portions of this press release regarding the results of the PEA. Dr. Deepak Malhotra of Resource Development Inc. is the independent Qualified Person who has reviewed and approved the metallurgical recoveries.
The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Standalone economics have not been undertaken for the indicated resources and as such no reserves have been estimated for the Project. There is no certainty that the economic results described in the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
