Golden Minerals Company announced additional assay results from 20 recently completed diamond drill holes and to announce it has commenced a reverse circulation drill program focusing on resource definition at its Rodeo gold-silver mine located in Durango State, Mexico. The reverse circulation program is being conducted by Major Drilling and will consist of 35 drill holes totaling approximately 2,500 meters. The program is designed to expand on the high-grade resource currently being mined and to drill several exploration targets located adjacent to the open pit. The reverse circulation drilling is expected to be completed in September. The Company has reported assay results from an additional 20 holes, totaling 1,253 meters, from the ongoing diamond drilling program that is exploring for the continuation of Au-Ag mineralization to the north of the current mining area. Drilling has intersected several wide zones of disseminated gold mineralization and has identified several additional high-grade zones that appear to be hosted in a series of silicified structures running parallel to the high-grade gold zones currently being mined. Highlights of the new assay results include: RDO_21_028 - 78.7m grading 1.06 g/t Au and 10.1 g/t Ag, Including 13.9m grading 2.88 g/t Au and 4.3 g/t Ag. RDO_021_022: 70.0m grading 0.56 g/t Au and 6.0 g/t Ag, Including 14.2m grading 1.07 g/t Au and 14.8 g/t Ag. RDO_021_018 - 64.4m grading 0.85 g/t Au and 8.6 g/t Ag. RDO_021_011A - 26.0m grading 0.82 g/t Au and 6.5 g/t Ag.
