GOLDEN MINERALS BEGINS DRILLING AT RODEO GOLD PROJECT IN DURANGO, MEXICO
Golden Minerals Company has commenced drilling at its Rodeo gold and silver property in Durango, Mexico.
Golden Minerals plans to drill approximately 20 holes to better define the high-grade core of the Rodeo deposit. The upcoming drill program will expand on the historic drilling campaigns that successfully tested multiple gold-quartz veins and breccias of the Rodeo low sulphidation vein system with encouraging results, as shown in the associated table.

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 toward the future development of the Rodeo project outlined in the recent preliminary economic assessment filed on May 28, 2020.
Warren Rehn, president and chief executive officer of Golden Minerals, commented: “The proximity of the Rodeo project to our existing processing facilities at Velardena 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 kilometres west of the company’s Velardena 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-metre core drilling program in 2016 and outlined a minable open pit with a high-grade resource base as shown in the associated table.

(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 break-even cut-off including trucking and processing costs per block was applied to a block model within the optimized shell.
