Santa Maria

At the Santa Mariamine west of Hildalgo de Parral, Chihuahua, which the Company has the right to acquire under an option agreement, Golden Minerals has recently completed an underground drilling program of 2,200 meters in 24 drill holes. Assay results are complete and the Company is evaluating the results to update the resource estimate and complete a Preliminary Economic Assessment during the second half of 2016.

Significant drill results including all intercepts of the Santa Mariavein of at least 0.5 meters true width are reported below:

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

Celaya

On August 2, 2016, the Company entered into an earn-in agreement with a wholly-owned subsidiary ofElectrum Global Holdings, L.P. ('Electrum') related to the Company's Celayaexploration project in Mexico. Golden Minerals received an upfront payment of $200,000and Electrum has agreed to incur at least $0.5 millionin 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 Celayaproject after incurring exploration expenditures totaling $2.5 millionduring 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 companyby incurring an additional $2.5 millionof 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 Celayaproject 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'sstanding 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 Latinaon the neighboring property, Naranjillo, we are seeing momentum toward the emergence of a new mining camp with similarities to the historic GuanajuatoDistrict, 45 kilometers to the northwest.'

Rodeo

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 Luisdel Cordero

Golden Minerals began a 20-hole, 4,600-meter exploration drilling program at the Santa Rosavein of the San Luisdel Cordero project in the first quarter 2016. The program was concluded in June 2016with 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 Diegosilver exploration property to Golden Tag Resources Ltd., the party holding the other 50 percent interest in the property. Golden Minerals received approximately $0.38 millionin cash, 2.5 million shares of Golden Tagand a 2 percent net smelter return royalty on production from the San Diegoproperty. Following this transaction, and including 5 million Golden Tagshares acquired in previous transactions, the Company holds approximately 10 percent of Golden Tag'soutstanding shares.
