GOLDEN MINERALS IDENTIFIES HIGH-GRADE GOLD AND SILVER VEINS AT YOQUIVO

Golden Minerals Company has released high-grade silver-gold assays from its Yoquivo project located in Chihuahua, Mexico.

Yoquivo sampling highlights:

• Six metres assaying 5.9 grams per tonne (g/t) gold and 937 g/t silver from the Pertenencia vein;
• Four m assaying 2.3 g/t Au and 489 g/t Ag from the Central breccia zone;
• 2.9 m assaying 2.3 g/t Au and 345 g/t Ag from the San Francisco vein;
• Six m assaying 1.7 g/t Au and 399 g/t Ag from the Pertenencia vein.

The Yoquivo district is located on the headwaters of the Mayo River in the northern part of the Sierra Madre Occidental, approximately 45 kilometres west of San Juanito. The property is located 32 km south of Agnico Eagle's Pinos Altos mine (2018 production estimated at 170,000 ounces Au) and 35 km southeast of the Ocampo mining district (a gold producer sold to Minera Frisco for $750-million (U.S.) in 2012).

The Yoquivo property covers an erosional window of andesites beneath Oligocene-aged rhyolites. Multiple silver-gold-bearing epithermal veins have been mapped and sampled. The two most important veins are the San Francisco and Pertenencia veins, both of which have been mapped and sampled over a two km strike length. Numerous splays and parallel structures have also been identified and sampled.

To date, 756 samples have been collected, and the sampling program has identified and sampled a series of low-sulphidation quartz veins and breccias. The most promising results from the surface sampling program are summarized in the associated table, with surface sample results shown in images on the company's website.

Note  
AuEq and AgEq are calculated using metal prices of Au at 
$1,120/ounce and Ag at $14/ounce for an 80:1 ratio; results were 
reported for samples returning greater than 300 g/t AgEq.
 

Complete results (from 756 samples collected to date) are available on the Golden Minerals website. There is also a more detailed surface map.

The sampling program has systematically collected channel samples from the 2.2 km long San Francisco vein as well as several splays and parallel structures. The San Francisco vein occurs as a series of quartz-calcite veins and vein breccias with widths up to 3.4 m.

A new vein, the La Nina vein, was discovered in the northwest of the property where it splits off from the main San Francisco vein. It consists of a prominent banded epithermal quartz-calcite vein up to 2.1 m wide which has been mapped and sampled along a 350 m strike length. Initial results have returned assays up to 3.4 g/t Au and 105 g/t Ag over 2.1 m width.

Exploration is now focusing on the Pertenencia vein which consists of a series of 0.5 m to three m wide quartz-calcite epithermal veins and breccias. The mineralization appears to be more silver rich compared with the San Francisco vein, but sampling is still in progress.

"Our progress to date in defining high-grade veins outcropping at surface at Yoquivo is excellent. We expect to continue with the surface work in preparation for identifying the best drill targets, which we plan to test in a drill program in 2019. The discovery of additional untested veins on the property is promising. We believe the Yoquivo district is emerging as a very interesting exploration play in this well-mineralized portion of the Sierra Madre," stated Warren Rehn, president and chief executive officer of Golden Minerals.

Next steps

Mapping and sampling have only been conducted on approximately 40 per cent of the property. Golden Minerals has commenced a regional exploration program to search for additional veins that might outcrop on the property. In addition, the company hopes to conduct underground mapping and sampling of the various accessible mine workings, including those of the Creel mine, the largest historic workings on the property. The targeting work is expected to lead up to a drill program to test the most promising portions of the veins in 2019.

About Yoquivo

Golden holds an option to purchase six concessions that comprise the Yoquivo property, totalling 2,367.6 hectares located in western Chihuahua state in northern Mexico, for payments totalling $500,000 over four years and subject to a 2-per-cent NSR (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.

Core is photographed and sawn in half with one-half retained in a secured facility for verification purposes. Sample preparation (crushing and pulverizing) is performed at an independent ISO 9001:2001-certified laboratory in Chihuahua or Zacatecas, Mexico. Prepared samples are direct shipped to an ISO 9001:2001-certified laboratory in Canada.
