Golden Minerals Drills 2.6m Grading 7.14 g/t Au and 2,058 g/t Ag at Yoquivo
Golden Minerals Drills 2.6m Grading 7.14 g/t Au and 2,058 g/t Ag at Yoquivo
GOLDEN, Colo.--(BUSINESS WIRE)--March 3, 2022--Golden Minerals Company (“Golden
Minerals”, “Golden” or the “Company”) (NYSE-A: AUMN and TSX: AUMN) is pleased to
report results from the final seven holes of its recently completed 21-hole drill program at the
Yoquivo gold-silver project in northwest Chihuahua state, Mexico. Highlights from the drilling
include:
2.6m @ 7.14 g/t Au and 2,058 g/t Ag
2.1m @ 1.26 g/t Au and 169 g/t Ag
1.4m @ 0.26 g/t Au and 149 g/t Ag
The drill program was comprised of 21 holes totaling 3,949m and explored the Pertenencia,
Esperanza and Dolar vein systems. Drill holes were designed to follow up on the high-grade
zones intersected by the Company’s 2020 drill program and to explore additional veins to
identify new high-grade zones. The Company reported previous results from this drilling
program on January 27, 2022 [link] and February 16, 2022 [link]. These results cover the final
seven holes drilled during the 2021 exploration season.
Significant results and drill-hole locations are summarized in the tables below, with complete
results available on the Company website. [link]

Drill hole YQ_021_016 was drilled to explore the southern continuation of the high-grade
mineralization intersected by hole YQ_021_006 (6.2m grading 17.19 g/t Au and 2,403.5 g/t Ag
(link)), and the drill hole intercepted a banded quartz-sulphide vein containing significant
argentite, galena and pyrite, surrounded by a wide zone of altered and silicified andesites and
stockwork veining.
Two drill holes explored the newly identified “Huga” vein which is located between the
Pertenencia and San Francisco vein systems. Surface mapping and sampling previously
identified a quartz vein along a 500m strike length along what is now the Huga vein that returned
good gold and silver values in a 2020 surface exploration program. The drill holes intersected a
number of quartz breccia veins that contained anomalous silver and gold values, with the best
intercept returning 1.4m @ 0.26 g/t Au and 149 g/t Ag.
The Company has also recovered drill core from a 2007 program completed by West Timmins
Mining in which West Timmins Mining drilled 2,470.75m in 8 holes. Golden Minerals’
geologists are currently relogging and resampling the drill core and will incorporate this data into
the Golden Minerals database.
The Company has recently submitted an application to the Secretariat of Environment and
Natural Resources (SEMARNAT) for a 50-hole, 10,000m drill program to allow the Company to
continue to drill at Yoquivo, with the aim of fully exploring the four major vein systems on the
property and discovering additional high-grade, gold-silver zones.
“Yoquivo continues to produce excellent results, with these final holes demonstrating that the
Pertenencia vein has the potential to contain significant high-grade, gold-silver mineralization.
Our drilling has now extended the Pertenencia vein system by approximately 700 meters to the
north and more than 100 meters to the south, and with the discovery of a new mineralized
structure, the Huga vein, demonstrates that there is unrealized potential at Yoquivo,” said Warren
Rehn, President and Chief Executive Officer of Golden Minerals. “We anticipate restarting
exploration at Yoquivo in the coming months.”
About Yoquivo
Golden holds an option to purchase seven concessions that comprise the Yoquivo property,
totaling 1,974.8 hectares located in western Chihuahua State in northern Mexico, for payments
totaling $0.75 million over four years and subject to a 2% net smelter return royalty on
production capped at $2 million. The claims cover an underexplored epithermal precious metals
district that shows similar mineralization to the adjacent Ocampo mining district, and the
Company, through systematic exploration, hopes to identify significant high-grade
mineralization.

To ensure reliable sample results, Golden Minerals uses a quality assurance/quality control
program that monitors the chain of custody of samples and includes the insertion of blanks,
duplicates, and reference standards in each batch of samples.
Quality Assurance / Quality Control
Diamond drilling was conducted by Eco Drilling México S. de R.L. de C.V with a Cortech CSD
1300G rig. Drill holes were drilled to depths ranging from 102m to 351m and were drilled at
azimuths of 140° or 310° and a dip ranging from -45° to -75°. No water was encountered during
drilling. Holes were positioned with a hand-held GPS (accuracy +/- 5 meters) and later surveyed
with a Differential GPS once the drilling campaign was completed.
Samples of the core were obtained using a diamond saw to cut the core in half, retaining one half
for a permanent core record, and the other sent for analysis.
Drill-core samples were shipped to ALS Chemex sample preparation facility in Chihuahua,
Chihuahua, Mexico for sample preparation and for analysis at the ALS laboratory in North
Vancouver, British Columbia, Canada. The ALS Chihuahua and North Vancouver facilities are
ISO 9001 and ISO/IEC 17025 certified. ALS Global in North Vancouver is a facility certified as
ISO 9001:2008 and accredited to ISO/IEC 17025:2005 from the Standards Council of Canada.
Samples were crushed to 70% passing 2mm (PREP-31) with a split of up to 250 grams
pulverized to 85% passing 75 micrometers (-200 mesh). The sample pulps and crushed splits
were transferred internally to ALS Global’s North Vancouver analytical facility for gold and
multi-element analysis. Pulps (30 gram split) are submitted for Au analysis by fire assay with
atomic absorption finish (Au-AA23) and silver samples were analyzed by atomic absorption
(Ag-AA45).
Over-limit Au (>10.0 g/t Au) and Ag (>1500 g/t Ag) samples are analyzed by fire assay with
gravimetric finish (Au-GRA22 and Ag-GRA21). Over-limit base metal samples (>10,000 ppm
or 1%) are re-analyzed inductively coupled plasma atomic emission spectrometry using
protocols for higher grade results (ICP-AES) for Cu, Pb and Zn (Cu-OG62, Pb-OG62, Zn-
OG62).
In-house quality control samples (blanks, standards, duplicates, preparation duplicates) were
inserted into the sample set by Golden Minerals. ALS Global conducts its own internal QA/QC
program of blanks, standards and duplicates, and the results were provided with the Company
sample certificates. The results of the ALS control samples were reviewed by Golden Minerals
and the Company’s QP and evaluated for acceptable tolerances.
All sample and pulp rejects are stored at the Company’s secure warehouse in Velardeña,
Durango pending full review of the analytical data, and future selection of pulps for independent
third-party check analyses, if required.
