GOLDEN, CO - /BUSINESS WIRE/ - March 22, 2022 – Golden Minerals Company (“Golden Minerals”, “Golden” or the “Company”) (NYSE-A: AUMN and TSX: AUMN) announces that a Technical Report (“TR”) has been completed for each of its Rodeo open pit gold-silver mine and its Velardeña Properties, both located in Durango State, Mexico.

Each TR has been completed in accordance with Canadian National Instrument 43-101 - Standards of Disclosure of Mineral Projects (“NI 43-101”). The Resources used for each report were developed by the independent engineering firm of Tetra Tech and comply with the requirements of NI 43-101. Preliminary results of each economic analysis are shown in pre-tax U.S. Dollars. The Company also plans to file a technical report summary pursuant to Subpart 1300 of Regulation S-K for each of the Rodeo mine and the Velardeña Properties in connection with its annual report on Form 10-K.

Rodeo

The Rodeo mine is currently in operation and the Rodeo TR assumes a life of mine (“LOM”) starting point of November 1, 2021. The TR assumes prices of $1,800/ounce (“oz”) gold (“Au”) and $25.00/oz silver (“Ag”). Mineral resources were calculated having an effective date of October 31, 2021 with a cutoff grade of 1.6 grams per tonne (“g/t”) for processing and 1.0 g/t for stockpiling.

Estimated Resources

Table 1

Capital and Operating Costs

Required capital costs for the Rodeo mine consist of an estimated $0.4 million for closure and reclamation. No additional capital is required at the mine. No capital costs are estimated for Plant 2 for the life of the Project. Estimated operating costs are shown below.

Table 2

Economic Analysis

The LOM (life of mine) consists of 24 months of operation and assumes 12 months to perform closure and reclamation. The starting point for the LOM is November 1, 2021. The pre-tax net present value (“NPV”) of the project is $22.9 million using a discount rate of 8%. Royalties are calculated at 2% for La Cuesta and 0.5% for the Mexico precious metals royalty.

Table 3

Sensitivity Analysis

Sensitivity analyses on metal price and operating costs were performed on the economic model results. Due to the lack of capital cost requirements, no sensitivity analysis was conducted on capital costs. Results of sensitivity analyses show that a reduction in gold price of $100/oz would result in a 10% reduction in NPV, while an increase in operating costs of 10% would result in a 9% decrease in NPV.

Velardeña

The Velardeña Technical report (TR) assumes prices of $1,744/oz gold, $23.70/oz silver, $0.97/pound (“lb”) lead (“Pb”) and $1.15/lb zinc (“Zn”). Mineral resources were calculated having an effective date of February 28, 2022, as diluted to a minimum of 0.7 meters and are reported at a $175 NSR cutoff. A federal precious metal royalty of 0.5% is assumed.

Estimated Resources

Table 4

Economic Analysis

Economic model results are summarized below. The model includes Measured, Indicated, and Inferred resources. Reclamation costs are assumed to be canceled by salvage value and are therefore not included. The LOM is 11 years, with a pre-tax NPV of $119 million using a discount rate of 8%.

Table 5

Sensitivity Analysis

Results of the sensitivity analyses show the project is most sensitive to operating costs and gold price. A 10% increase in operating costs results in a 16% reduction in project NPV. Due to the sensitivity to operating costs, efforts to control or reduce the operating costs are material to the economic success of the project.

Cautionary Note Regarding Inferred Resources

The discounted cash flows shown above are prepared in compliance with NI 43-101. There is no certainty that the economic results described above will be realized. The Company proceeded to production at the Rodeo project without completion of customary feasibility studies demonstrating the economic viability of the Rodeo project, and may elect to do likewise at the Velardeña Properties. A mine production decision that is made without a feasibility study carries additional potential risks which include, but are not limited to, (i) increased uncertainty as to projected initial and sustaining capital costs and operating costs, rates of production and average grades, and (ii) the inclusion of Inferred Mineral Resources, as defined by NI 43-101 that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be converted to a Mineral Reserve, as defined by NI 43-101. Mine design and mining schedules, metallurgical flow sheets and process plant designs may require additional detailed work and economic analysis and internal studies to ensure satisfactory operational conditions and decisions regarding future targeted production.

No mineral reserves have been estimated for either the Rodeo mine or the Velardeña Properties. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The economic model for each of the Rodeo project and the Velardeña Properties is preliminary in nature and includes inferred mineral resources that are too speculative geologically to have economic considerations applied to them that would enable the inferred mineral resources to be classified as mineral reserves, and there is no certainty that the preliminary economic model for the Rodeo project, the Velardeña Properties, or both, will be realized.
