GOLDEN, Colo., Sept. 12, 2019 (GLOBE NEWSWIRE) -- Golden Minerals Company (“Golden Minerals”, “Golden” or “the Company”) (NYSE American and TSX: AUMN) has released final results from the 2019 drilling program conducted at its El Quevar silver property located in Salta Province, Argentina.  3,004 meters were drilled in 19 holes.

A new shallow high-grade zone was partially outlined in the Vince area about two kilometers southwest of the known Yaxtché deposit.  Four drill holes cut silver intercepts with grades of 500 to over 600 grams per tonne (g/t) silver (Ag) over widths of 1 to 4 meters (m).  These results extend a historical drill intercept by about 200 meters northeast along strike. The zone is open to the north. 

Other significant results of the program include a 2.1m interval grading 340 g/t Ag, in Yaxtché East.  This hole represents an approximate 50m step out from previous drilling and demonstrates the potential to add to the mineral resources in the northeast sector of the Yaxtché deposit.  Drilling at the Argentina prospect located approximately one kilometer east of Yaxtché has also returned silver values in one drill hole, with 2m of 358 g/t Ag.  These results coincide with previous drilling in the area (8m of 779 g/t Ag) and are considered encouraging for the area to host mineralization of potential economic significance.

The Yaxtché deposit is an intermediate-sulfidation epithermal silver-gold system within the Quevar volcanic complex.  All holes drilled to date have intercepted highly altered dacitic and volcaniclastic units with mineralization occurring within an envelope of advanced argillic alteration typical of this deposit type.  Outside of the Yaxtché area there are expansive zones of hydrothermal alteration which are considered highly prospective for additional mineralization.

The drilling program commenced in late February 2019 with the goals of extending the strike length of the Yaxtché deposit and testing prospective targets outside of the current Mineral Resource area.  The currently-defined resource includes over 45 million ounces of Indicated silver resources at an average grade of 482 g/t silver1 and covers only the 20-hectare Yaxtché deposit area within the property’s expansive 57,000-hectare boundaries.

Significant intercepts from the 19 completed holes of the 2019 drilling program include:

Vince Area

  • 658 g/t Ag over 1.0m
  • 306 g/t Ag over 4.0m
  • 513 g/t Ag over 1.0m
  • 626 g/t Ag over 3.0m
  • 605 g/t Ag over 1.9m

Argentina Area

  • 565 g/t Ag over 1.0m
  • 341 g/t Ag over 1.9m

Yaxtché East Area

  • 340 g/t Ag over 2.1m
  • 249 g/t Ag over 0.8m
  • 246 g/t Ag over 2.0m
  • 218 g/t Ag over 2.0m
  • 194 g/t Ag over 1.1m
  • 174 g/t Ag over 7.0m
  • 1.0 g/t Gold (Au) over 11.6m

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

This press release uses the terms "mineral resources" and "indicated mineral resources" which are defined in and required to be disclosed by NI 43-101. We advise U.S. investors that these terms are not recognized under the 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. US investors are cautioned not to assume that any or all of Minerals 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 and other SEC filings.

Forward?Looking Statements

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended, and applicable Canadian securities legislation, including statements regarding expectations surrounding the geologic potential of the El Quevar project. These statements are subject to risks and uncertainties, including:  the reasonability of the economic assumptions at the basis of the results of the El Quevar PEA and technical report; changes in interpretations of geological, geostatistical, metallurgical, mining or processing information; and interpretations of the information resulting from future exploration, analysis or mining and processing experience.  Golden Minerals assumes no obligation to update this information.
