The objectives of the drilling program are to provide greater detail on the gold mineralization at Rodeo and to provide sample material for metallurgical and geotechnical testing, an important step towards the future development of the Rodeo project outlined in the recent Preliminary Economic Assessment filed on May 28, 2020 (link), Drips, D., April 1, 2020, NI 43-101 Technical Report, Preliminary Economic Assessment, Rodeo Project, Rodeo, Durango, Mexico, Mineral Resources Engineering, Salt Lake City, UT.

Warren Rehn, President and Chief Executive Officer of Golden Minerals, commented, "The proximity of the Rodeo project to our existing processing facilities at Velardeña presents an excellent opportunity to generate significant revenue from Rodeo starting in early 2021. We are optimistic that the drilling will improve our confidence in the deposit and enable us to continue to move towards development."

Rodeo is an open pit gold project within a 1,900-hectare claim located in the State of Durango, Mexico, approximately 80 kilometers west of the Company's Velardeña Properties and processing mills. Golden acquired the Rodeo property subject to a royalty interest due to La Cuesta International in the second quarter 2015, prior to which exploration by other companies identified a gold-bearing system exposed at the surface. Golden conducted a 2,080-meter core drilling program in 2016 and outlined a minable open pit with a high-grade resource base of:

ClassificationCut-off grade
g/t Au
Tonnes (Mt)Au g/tAg g/tAu (Koz)Ag (Koz)
Indicated0.830.43.31146200

Notes:

(1) Cut-off grade and Au equivalent calculated using metal prices of $1,220 and $17 per troy ounce of Au and Ag, recoveries of 77% and 90% Au and Ag.
(2) Mineral resources have been constrained by a pit shell calculated using the Lerch Grossman algorithm with cost inputs per tonne of $7.50 mining, $10 trucking, and $20 processing. A breakeven cut-off including trucking and processing costs per block was applied to a block model within the optimized shell.
(3) Metal prices do not exceed three-year trailing average as of the end of December 2016, per United States Securities and Exchange Commission (the “SEC”) guidance.
(4) Reported indicated mineral resources are equivalent to mineralized material under SEC Industry Guide 7.
(5) Resource reported in technical report: Elson, G., 2017, NI 43-101 Technical Report, Mineral Resource Estimate, Rodeo Project, Rodeo, Durango, Mexico, Tetra Tech, Golden, CO, 91pp.

Cautionary Note to United States Investors Regarding Estimates of Indicated Mineral Resources

This press release uses the terms "mineral resources" and "indicated mineral resources" which are defined in, and required to be disclosed by, Canadian National Instrument NI 43-101 (“NI 43-101”). We advise U.S. investors that these terms are not recognized under SEC Industry Guide 7. Accordingly, the disclosures regarding mineralization in this news release may not be comparable to similar information disclosed by Golden Minerals in the reports it files with the SEC. The estimation of measured resources and indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any or all mineral resources are economically or legally mineable or that these mineral resources will ever be converted into mineral reserves. In addition, the SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant “reserves” as in-place tonnage and grade without reference to unit amounts. U.S. investors are urged to consider closely the disclosure in our Form 10-K for the year ended December 31, 2019 and other SEC filings.
