Warren Rehn, President and Chief Executive Officer of Golden Minerals, commented, “These excellent drill results from Yoquivo highlight its potential to host economic gold-silver mineralization. This recent drilling has identified multiple veins with potentially economic gold-silver grades, including a newly discovered vein without previous historic mining within our district scale property holdings. We plan to follow with a second phase drill program which could start in the next few months.”

Yoquivo covers a large, low-sulfidation epithermal vein system with limited historic production. The Company has identified four separate vein systems in which surface sampling has returned grades up to 4,050 g/t silver and 27.7 g/t gold from surface. See Golden Minerals’ press release dated Oct. 31, 2018 for details: AUMN Identifies High-Grade Gold and Silver Veins at Yoquivo.

Golden Minerals completed the phase one drill program in December 2020 (see related press release here), and drilled 15 holes totalling approximately 3,400 meters exploring the four known vein systems exposed on the property. The exploration program was designed to target the Pertenencia, San Francisco and Esperanza vein systems to better understand the nature and distribution of the gold-silver mineralization. Of substantial interest is the discovery of a new vein parallel to and east of the Pertenencia vein. While the other principal veins have been partially mined from surface to the water table (up to 130 meters) in the case of San Francisco and Pertenencia, and over a much less extensive vertical interval in the case of El Dolar and Esperanza, the new vein is unmined from surface. Summary assay results from the 2020 drill program are shown as follows:

Notes:

• Estimated true widths range from 65% to 90% of drilled widths depending on dip of the vein and inclination of the hole.

• AgEq calculations for reported drill results are based on USD $20.00/oz Ag, $1,500/oz Au. The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices.

• Intervals have been simplified to one decimal place.
