Golden Minerals Reports Continued Exploration Success at Yoquivo Gold-Silver Project, Mexico
Content was created on: February 7, 2023 GOLDEN, CO - /BUSINESS WIRE/ - February 7, 2023 – Golden Minerals Company (“Golden Minerals”, “Golden” or the “Company”) (NYSE-A: AUMN and TSX: AUMN) is pleased to report results from the final 10 holes of the third drill program conducted at its Yoquivo gold-silver project in northwest Chihuahua state, Mexico. Highlights from the program include:
*Widths reported are true widths The 2022 drill program commenced in May 2022 and was comprised of 34 holes totaling 9,268.35m. The program was designed to follow up on high-grade intercepts from the Company’s 2020 and 2021 drilling campaigns. To date, the Company has drilled 70 drill holes totaling over 16,000 meters at Yoquivo. The primary focus of the 2022 third drilling program was to sufficiently drill the Pertenencia vein system in order to advance the project towards an initial mineral resource estimate compliant with Canadian National Instrument 43-101 (“NI 43-101”) and Item 1300 of Regulation S-K promulgated by the SEC. The Company began work on the mineral resource estimate in November 2022 and currently expects it should be completed in the first quarter 2023. Partial results from the 2022 drill program were published on July 7th, 2022 (link) and September 12th, 2022 (link).

*True widths on the La Huga and San Francisco hanging wall veins are unknown as they have only been intersected by one or two drill holes that don’t allow for the true thicknesses to be accurately measured. Drill hole collar location table:

These last holes from the 2022 program continue to return high-grade gold and silver assays from both the Pertenencia and San Francisco vein systems, and with each new drilling campaign we continue to discover additional veins and extend mineralization to greater depths than previously recognized,” said Warren Rehn, President and Chief Executive Officer of Golden Minerals. “We are especially excited about hole YQ_22_034 which demonstrates that the San Francisco Footwall vein appears to be a very robust discovery. We have drilled only a small portion of the known veins in the district with numerous excellent intercepts and showings still to be offset and tested.” About Yoquivo Golden owns seven concessions that comprise the Yoquivo property, totaling 1,974.8 hectares located in western Chihuahua state in northern Mexico. The concessions owned by Golden are subject to net smelter return royalties of 2 to 3% on production, capped at $3 million. Review by Qualified Person and Quality Control The technical contents of this press release have been reviewed by Matthew Booth, a Qualified Person for the purposes of NI 43-101. Mr. Booth has over 19 years of mineral exploration experience and is a Qualified Person member of the American Institute of Professional Geologists (CPG 12044). To ensure reliable sample results, Golden Minerals uses a quality assurance/quality control (“QA/QC”) program that monitors the chain of custody of samples and includes the insertion of blanks, duplicates, and reference standards in each batch of samples. Quality Assurance / Quality Control Diamond drilling was conducted by Eco Drilling México S. de R.L. de C.V., with a Coretech CSD 1300G rig. Drill holes were drilled to depths ranging from 158m to 518m and were drilled at azimuths of 290° to 330o and a dip ranging from -45o to -65o. No water was encountered during drilling. Holes were positioned with a hand-held GPS (accuracy +/- 5 meters) and later surveyed with a Differential GPS once the drilling campaign was completed. Samples of the core were obtained using a diamond saw to cut the core in half, retaining one half for a permanent core record, and the other sent for analysis. Drill-core samples were shipped to the ALS Chemex sample preparation facility in Chihuahua, Chihuahua, Mexico for sample preparation and for analysis at the ALS laboratory in North Vancouver, British Columbia, Canada. The ALS Chihuahua and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. ALS Global in North Vancouver is a facility certified as ISO 9001:2008 and accredited to ISO/IEC 17025:2005 from the Standards Council of Canada. Samples were crushed to 70% passing 2mm (PREP-31) with a split of up to 250 grams pulverized to 85% passing 75 micrometers (-200 mesh). The sample pulps and crushed splits were transferred internally to ALS Global’s North Vancouver analytical facility for gold and multi-element analysis. Pulps (30 gram split) are submitted for Au analysis by fire assay with atomic absorption finish (Au-AA23) and silver samples were analyzed by atomic absorption (Ag-AA45). Over-limit Au (>10.0 g/t Au) and Ag (>1500 g/t Ag) samples are analyzed by fire assay with gravimetric finish (Au-GRA22 and Ag-GRA21). Over-limit base metal samples (>10,000 ppm or 1%) are re-analyzed with inductively coupled plasma atomic emission spectrometry using protocols for higher grade results (ICP-AES) for Cu, Pb and Zn (Cu-OG62, Pb-OG62, Zn-OG62). In-house quality control samples (blanks, standards, duplicates, preparation duplicates) were inserted into the sample set by Golden Minerals. ALS Global conducts its own internal QA/QC program of blanks, standards and duplicates, and the results were provided with the Company sample certificates. The results of the ALS control samples were reviewed by Golden Minerals and the Company’s Qualified Person and evaluated for acceptable tolerances. All sample and pulp rejects are stored at the Company’s secure warehouse in Velardeña, Durango, pending full review of the analytical data, and future selection of pulps for independent third-party check analyses, if required. About Golden Minerals Golden Minerals is a growing gold and silver producer based in Golden, Colorado. The Company is primarily focused on producing gold and silver from its Rodeo Mine and advancing its Velardeña Properties in Mexico and, through partner-funded exploration, its El Quevar silver property in Argentina, as well as acquiring and advancing selected mining properties in Mexico, Nevada and Argentina.
