Project
GOLDEN, Colo.--(BUSINESS WIRE)--July 7, 2022--Golden Minerals Company (“Golden
Minerals”, “Golden” or the “Company”) (NYSE-A: AUMN and TSX: AUMN) is pleased to
report results from the first nine holes drilled in a third drill program conducted at its Yoquivo
gold-silver project in northwest Chihuahua state, Mexico. Highlights from the drilling include:
• 2.2m @ 10.21 g/t Au and 138.8 g/t Ag
• 0.4m @ 30.80 g/t Au and 5260.0 g/t Ag
• 4.2m @ 0.16 g/t Au and 229.2 g/t Ag
• 80.1m @ 0.89 g/t Au and 64.5 g/t Ag
• 1.7m @ 0.13 g/t Au, 354.6 g/t Ag
The 2022 drill program commenced in May 2022 and 17 holes totaling 4,033m have been drilled
to date. This drill program is designed to follow-up on high-grade intercepts reported from the
Company’s 2021 drilling activity, as well as to drill several holes exploring other interesting vein
systems on the property. 2021 drill program results were reported on January 27, 2022 [link],
February 16, 2022 [link] and March 3, 2022 [link].
Significant results are summarized in the table below, with complete results available on the

“This most recent drilling has focused on testing the Pertenencia vein system to extend the
known mineralized strike length into previously untested areas. The Pertenencia vein has
continued to return strong gold-silver grades, and the vein remains open to depth and to the
north. The discovery of multiple, previously unknown, high-grade gold-silver structures,
particularly the Camila vein, demonstrates that there is also significant potential at Yoquivo to
discover additional high-grade structures on the property. The current drill program is expected
to allow us to report an initial gold-silver resource on the property later this year,” said Warren
Rehn, President and Chief Executive Officer of Golden Minerals.
About Yoquivo
Golden owns six concessions and holds an option to purchase one additional concession that
comprise the Yoquivo property, totaling 1,974.8 hectares located in western Chihuahua State in
northern Mexico. The remaining concession can be purchased for payments totaling $0.2 million
over four years. The six concessions already owned by Golden are subject to a 2% net smelter
return royalty on production capped at $3 million.
Review by Qualified Person and Quality Control
The technical contents of this press release have been reviewed by Matthew Booth, a Qualified
Person for the purposes of NI 43-101. Mr. Booth has over 18 years of mineral exploration
experience and is a Qualified Person member of the American Institute of Professional
Geologists (CPG 12044).
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 Coretech CSD
1300G rig. Drill holes were drilled to depths ranging from 143m to 306m and were drilled at
azimuths of 53° to 318° 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.
