Golden Minerals Company (NYSE American:AUMN) (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:

The following table summarizes the results received to date related to the 2019 drilling program:
|Significant Intervals – El Quevar Drill Results September 2019|
|Hole ID||Total Depth (m)||From (m)||To (m)||Width (m)||Ag (g/t)||Au (g/t)||Project Area|
|QVD-389||139.6||No significant intervals||Yaxtche East|
|QVD-390||82.6||No significant intervals||Yaxtche East|
|QVD-393||257.3||No significant intervals||Argentina|
|QVD-395||104.5||No significant intervals||Argentina|
|QVD-397||115.4||No significant intervals||Argentina|
|QVD-398||145.9||No significant intervals||Perlita|
|QVD-399||328.8||No significant intervals||Yaxtche West|
|QVD-400||506.0||No significant intervals||Yaxche West|
|QVD-401||251.0||No significant intervals||Carolina|
|QVD-404||79.0||No significant intervals||Vince|
|QVD-406||111.0||No significant intervals||Vince|
Note: 100 g/t Ag and/or 1.0 g/t Au cutoff grades used. Some drill hole intervals have been composited from multiple adjacent samples, and in some cases may contain up to one meter of core with less than 100 g/t Ag if the overall interval weighted average is greater than 100 g/t Ag. Individual assay intervals will be reported on the Golden Minerals website. “Significant Interval” is defined as at least 0.8 meters measured width of at least 100 g/t Ag, or 1.0 g/t Au. All widths reported as measured.
