Golden Minerals' Mining Underway; Additional Vein Added To Plan

GOLDEN, Colo., July 14, 2014 /PRNewswire/ -- Golden Minerals Company ("Golden Minerals" or the "Company") (NYSE MKT: AUMN) (TSX: AUM) is pleased to announce it restarted mining at its Velardena Properties on July 1, 2014. Velardena was previously held in care and maintenance after production was suspended in mid-2013 due to depressed precious metals prices. The Company used the operating down time to conduct a 9,000-meter drilling program and to develop a new mining plan that indicates positive net cash flow from the Velardena Properties after production is ramped up through the second quarter 2015. Planning economics assume precious metals prices of $20 per ounce silver and $1,250 per ounce gold.

Golden Minerals has hired approximately 50 employees who are now working at Velardena, including a new General Manager, managers for both the mine and mill and roughly 40 miners. The Company has scheduled workers for two ten-hour shifts per day. Underground activity is currently focused on driving a ramp to access the Terneras vein at deeper levels and a crosscut to the San Mateo East vein, as well as stoping on the San Mateo West and Roca Negra veins, where mined material is removed from the mine in 20-ton trucks. The Company expects mining of the Terneras vein to commence during the fourth quarter 2014.

The Roca Negra vein is sub-parallel to the Terneras vein and about 50 meters to the north. The Company did not consider the Roca Negra vein in its initial restart plan; however, based on recent drill results now partially confirmed by underground drifting, the Roca Negra vein should be an important and positive addition to the mine plan. These recent drill results are from holes drilled to test the portions of the Terneras and Roca Negra veins that Golden Minerals will be able to access early in the mining sequence (with the exception of TS-08, which intersects the eastern portion of the Roca Negra vein).

Drill results not previously reported include significant gold (Au) and silver (Ag) grades from the Roca Negra and Terneras veins. Selected results include:

• TS-13 Roca Negra vein: 1.4 meters of 12.2 grams per tonne (gpt) Au and 107 gpt Ag
• TS-15 Terneras vein: 0.9 meters of 5.5 gpt Au and 100 gpt Ag
• TS-17: Roca Negra vein: 0.4 meters of 6.6 gpt Au and 3,860 gpt Ag
• TS-18 Terneras vein: 0.8 meters of 7.6 gpt Au and 241 gpt Ag

A table of selected drill results follows:

Complete drill results will be posted on the Golden Minerals website at www.goldenminerals.com.

Golden's Senior Vice President of Exploration and Chief Geologist Warren Rehn has spearheaded Velardena's drilling and restart planning efforts during the last year. Rehn commented, "I am extremely pleased with our team's dedication and successful execution to date. We have employees in Mexico who go well beyond the call of duty in performing their roles, and we are proud to count them as team members. We are delighted to have restarted mining slightly ahead of schedule and we look forward to successfully driving Velardena to profitability."
