“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.

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.
