Golden Minerals Drills 18m Grading 2.9 g/t Gold at Rodeo
Gold-Silver Mine
GOLDEN, CO - /BUSINESS WIRE/ - October 19, 2021 – Golden Minerals Company (“Golden Minerals”, “Golden” or
the “Company”) (NYSE-A: AUMN and TSX: AUMN) is pleased to announce assay results from 25 recently completed
reverse circulation (“RC”) drill holes at its Rodeo gold-silver mine located in Durango State, Mexico.
The company has drilled 47 RC holes totaling 3 ,187m, focusing on resource expansion and e xploration of several
targets located adjacent to the open pit. The reverse circulation drilling was completed in early October.
Highlights from the initial RC holes include:
• RRC_021_018 returned 18m grading 2.3 g/t Au and 5 g/t Ag within 54m grading 1.0 g/t Au and 5 g/t Ag
• RRC_021_020 returned 8m grading 2.4 g/t Au and 16 g/t Au within 26m grading 1.7 g/t Au and 12 g/t Ag
• RRC_021_021 returned 24m grading 2.2 g/t Au and 18 g/t Ag within 56m grading 1.3 g/t Au and 17 g/t Ag
• RRC_021_022 returned 8m grading 3.9 g/t Au and 5 g/t Ag within 56m grading 1.0 g/t Au and 4 g/t Ag
• RRC_021_025 returned 18m grading 2.9 g/t Au and 11 g/t Ag within 52m grading 1.3 g/t Au and 6 g/t Ag
Drilling has intersected several wide zones of disseminated gold mineralization and has identified several additional
high-grade zones that appear to be hosted in a series of silicified structures running parallel to the high -grade gold
zones currently being exploited. The mineralization in these new zones is very similar to the material currently being
mined and consists of highly silicified epithermal veins and breccias hosted in felsic volcanic rocks.
Warren Rehn, President and Chief Executive Officer of Golden Minerals, commented, "The initial RC drill results are
very positive. The gold-bearing intervals expand on the known zones of mill-grade gold mineralization to the south
of the current pit and indicate that there is strong potential for Rodeo to h ost additional profitable tonnage, at
current prices, to the south and west of the current pit.”

Significant results are summarized in the table below, with complete results available on the Company website. [link]
Note: Intervals in the table represent drilled length. It is expected that true thickness is approximately 80% of drilled
length as drill holes were drilled perpendicular to the gold mineralization that dips at approximately 25 degrees to
the northeast. Intervals and grades have been rounded to either one or two decimal places.

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 17 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

Quality Assurance / Quality Control
RC drilling was conducted with a Prospector W750 articulated carrier mounted RC drill rig provided by Major Drilling.
Holes were drilled at an azimuth of 240° or 60o and a dip ranging from -45o to -60°. Drill holes were drilled to depths
ranging FROM 36m to 108m. 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 hole was competed. Sampling was
conducted from the drill rig cyclone at 2-meter drill intervals. Each 2-meter sample was riffle split to approximately
6 kilograms samples for assay. RC chips were logged at the drill rig and a small, 100g sample was collected and logged
and stored in chip-trays onsite.
Drill-core, reverse circulation drill chips and rock 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.
The ALS Chihuahua and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. ALS Global in North
Vancouver, British Columbia, Canada, is a facility certified as ISO 9001:2008 and accredited to ISO/IEC 17025:2005
from the Standards Council of Canada.
The samples were crushed to 70% passing 2mm (PREP-31) and a split of up to 250 grams pulverized to 85% passing
75 micrometres (-200 mesh). The sample pulps and crushed splits were transferred internally to ALS Global’s North
Vancouver, Canada analytical facility for gold and multi-element analysis. Pulps (30gram split) are submitted for Au
analysis by Fire Assay with Atomic Absorption finish (Au -AA23) and silver samples were analyzed by an atomic
absorption (Ag-AA45).
Over-limit Au and Ag samples are analyzed by Fire Assay with Gravimetric Finish Ore Gr ade (Au-GRA22 and Ag -
GRA21). Overlimit base metals are analyzed by Four Acid Digestion followed by Ore Grade Inductively Coupled
Plasma Atomic Emission Spectrometry (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 cer tificates. 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.
