GOLDEN, Colo., Nov. 15, 2018 (GLOBE NEWSWIRE) — Golden Minerals Company (NYSE American and TSX: AUMN) (“Golden Minerals”, “Golden” or “the Company”) is pleased to announce it has acquired the Navegantes project in southern Chihuahua state, Mexico, where recent surface and underground sampling have returned high-grade silver values from a series of epithermal silver-base metal veins outcropping on the property.
Navegantes sampling highlights:
- 1 meter (“m”) assaying 1,585.5 g/t Ag
- 1.45m assaying 759.2 g/t Ag
- 1.1m assaying 638.9 g/t Ag
- 2.1m assaying 472 g/t Ag
The project consists of six concessions totaling 521 hectares and is located approximately 60km northwest of the San Francisco del Oro-Santa Barbara District where the company’s Santa Maria project is located. Initial sampling and mapping have identified extensive zones of oxidized and leached epithermal quartz veining over an 800m strike length that has delivered high silver grades.

Mr. Warren Rehn, President and Chief Executive Officer of Golden Minerals, said; “Navegantes is an exciting prospect that hasn’t been systematically explored even though it is located in an area of several modern major discoveries. We were pleasantly surprised by the high-grade surface silver assays from heavily weathered and leached veins outcropping on the surface.
“This project was identified by our generative exploration team that is searching for under-explored projects in central Mexico to allow the company to add high-quality, early-stage projects that can be advanced quickly to create value for our shareholders.”

The mineralization occurs as iron oxides, within quartz veins that range up to 2m in width and are exposed over strike lengths in excess of 800m. Based on historic mines and prospects in the San Francisco del Oro-Santa Barbara and Hidalgo de Parral districts, we believe there exists excellent potential to define significant silver mineralization at depth.
Golden Minerals collected 103 surface and underground chip channel and grab samples from vein exposures, mine workings and mine dumps. Results from this initial sampling program are summarized in Table 1, with surface sample results shown in Figure 3.

About Navegantes
Golden Minerals holds an option to purchase six concessions totaling 521 hectares by paying $0.4M over three years. The property is located in southwestern Chihuahua state, in northern Mexico. The project covers two vein systems (Navegantes and San Pedro-San Francisco) as well as a number of smaller subsidiary veins. The property is located 68km northwest of Grupo Mexico’s Santa Barbara operation (6,000 tonnes per day) and 63km northwest of Frisco’s San Francisco Mine (4,000 tonnes per day). The project is also 61km south of Sunshine Mining’s Los Gatos project. The Navegantes property covers an underexplored epithermal precious silver-base metal district that shows similar mineralization to the adjacent Parral Mining District. The Company, through systematic exploration, hopes to identify significant high-grade mineralization.
