Golden Minerals Announces Positive Initial Results from its Rodeo Gold-Silver Mine Expansion Drilling, Including 14.7m @ 3.94 g/t Au

Golden, Colorado, UNITED STATES

GOLDEN, Colo., June 10, 2021 (GLOBE NEWSWIRE) -- Golden Minerals Company (NYSE American and TSX: AUMN) (“Golden Minerals”, “Golden” or “the Company”) is pleased to announce initial results from its ongoing expansion drill program at its Rodeo open pit gold mine in Durango State, Mexico.

The Company announced in March 2021 it was beginning a program encompassing approximately 2,000 meters of exploration drilling at selected near-surface targets located immediately adjacent to the current open pit, as well as additional near-site surface targets. The program is being conducted to outline possible extension of the life of the Rodeo mine well beyond the currently estimated life of around 2.5 years. To date the exploration program has drilled 606 meters through the first ten holes.

Highlights of the program’s initial results include the following:


  • 14.65m grading 3.94 g/t Au and 8.0 g/t Ag including
  • 9.30m grading 5.38 g/t Au and 9.8 g/t Ag;
  • 3.70m grading 7.02 g/t Au and 21.5 g/t Ag including
  • 0.90m grading 21.09 g/t Au and 50.4 g/t Ag


  • 13.75m grading 2.64 g/t Au and 10.5 g/t Ag including
  • 1.60m grading 9.17 g/t Au and 18.5 g/t Ag;
  • 6.35m grading 1.41 g/t Au and 36.4 g/t Ag including
  • 2.70m grading 1.94 g/t Au and 58.5 g/t Ag


  • 3.80m grading 2.69 g/t Au and 26.0 g/t Ag including
  • 2.35m grading 3.31 g/t Au and 32.2 g/t Ag

Warren Rehn, President and Chief Executive Officer of Golden Minerals, commented, “We are pleased with the first results of the near-pit exploration drilling program, as these intercepts indicate that we should be able to expand the currently modelled high-grade zone to the north. The intercept in hole 10 is a newly discovered zone that is open up and down dip and to the northwest. These encouraging results demonstrate that the current pit can likely be expanded with additional drilling which could lead to an increase in the life of mine.”

Note: Historic drill holes are not shown in the location map. Prior drilling is at about a 25-meter spacing throughout the high-grade mineralized area.

The continuation of the exploration program will include additional near-pit targets, as well as other surface targets within a few hundred meters of the currently planned open pit, with the goal of finding additional high-grade mineralization to extend the life of mine.

Summary assay results are shown as follows:
