Management believes that drill results support the results of its previous resource estimation at Santa Maria and should allow greater confidence in the location of the higher grade ore shoots.  Complete results will be reported on the Golden Minerals website with a location map.


On August 2, 2016, the Company entered into an earn-in agreement with a wholly-owned subsidiary of Electrum Global Holdings, L.P. ("Electrum") related to the Company's Celayaexploration project in Mexico.  Golden Minerals received an upfront payment of $200,000 and Electrum has agreed to incur at least $0.5 million in exploration expenditures in the first year, reduced by costs previously incurred in its ongoing surface exploration program on the property.  Electrum can elect to acquire an undivided 60 percent interest in a joint venture company to be formed to hold the Celaya project after incurring exploration expenditures totaling $2.5 million during the first three years of the agreement.  Electrum would be the manager of the joint venture.  If the Company did not contribute to additional exploration or development expenditures after the initial earn-in period, Electrum would have the right to earn an additional 20 percent interest in the joint venture company by incurring an additional $2.5 million of exploration or development expenditures over a second three year period.  Following the second earn-in period, the Company could maintain its 20 percent interest or its interest could ultimately be converted into a 10 percent net profits interest.   

The 6,200-hectare silver and gold Celaya project contains a strongly developed alteration system on the main Mexico Silver belt trend, located 10 kilometers east of Plata Latina'sNaranjillo silver and gold discovery and 45 kilometers southeast of and on trend with the historic Guanajuato District.  Golden has conducted mapping and sampling activities at Celayasince 2012.  The Company completed a 2,000 meter, three-hole drilling program in 2015 that identified epithermal gold and silver mineralization beneath a portion of the widespread clay-silica alteration on the claims comprising the project.  

Warren Rehn, President and Chief Executive Officer of Golden Minerals, stated, "We are very pleased to have Electrum as a partner in this exploration project.  The consummation of this agreement with a company of Electrum's standing confirms our views regarding the importance of this exploration discovery and the prospective nature of the property to potentially contain a significant epithermal silver deposit.  Combined with the recently reported agreement between Fresnillo and Plata Latina on the neighboring property, Naranjillo, we are seeing momentum toward the emergence of a new mining camp with similarities to the historic Guanajuato District, 45 kilometers to the northwest."


In June 2016, Golden Minerals began a 2,000-meter core drilling program at the Rodeo gold project located approximately 80 kilometers west of the Velardena Properties in Durango State, Mexico, at an estimated cost of $0.3-$0.4 million. 

San Luis del Cordero

Golden Minerals began a 20-hole, 4,600-meter exploration drilling program at the Santa Rosa vein of the San Luis del Cordero project in the first quarter 2016.  The program was concluded in June 2016 with the final assessment of results available in July.  Results did not expand or advance the resource estimate of the previous owner and the Company's evaluation indicated that further work on the project is not likely to meet near-term objectives.  Golden Minerals intends to terminate the farm-in arrangement for the property in August 2016.

San Diego

On August 2, 2016, the Company sold its 50 percent interest in the San Diego silver exploration property to Golden Tag Resources Ltd., the party holding the other 50 percent interest in the property.  Golden Minerals received approximately $0.38 million in cash, 2.5 million shares of Golden Tag and a 2 percent net smelter return royalty on production from the San Diego property.  Following this transaction, and including 5 million Golden Tag shares acquired in previous transactions, the Company holds approximately 10 percent of Golden Tag'soutstanding shares.
