Development to the southern lobe of the Main Zone began in January, and ore is now mined from two development headings, with two levels being prepared for production. Ore from three additional headings will be added to the stockpile within the next week. The primary ramp to the bulk of the deposit is progressing, with 480 m of advance needed to reach the bottom of the Main Zone. Process plant modifications are progressing, with initial concentrate production from San Rafael expected before the end of September 2017.

The underground resources carry 6 K Oz Au, 1.3 M Oz Ag; 38 K Oz Au, 9.1 M Oz Ag as indicated and inferred resources respectively. The total hard rock resource is 25.9 M tonnes @ 0.52 g/t Au, 19g /t Ag, containing 436 K Oz Au, 15.7 M Oz Ag and 6.6 M tonnes @ 0.52 g/t Au, 89 g/t Ag as indicated and inferred resources respectively.

  • Levon Resources Ltd. completed 5,655 m of core drilling in 18 holes at its Cordero project in Chihuahua. “The 2017 holes were drilled to test for near surface, higher gold grades within multiple rhyolite intrusives that make up the volcanic Cordero Felsic Dome Complex, and higher grade mineralization in contact breccia bodies that could improve a starter open pit configuration in the southwest part of the Resource.” Assays are pending.
  • Mexican Gold Corp. filed at SEDAR the technical report on the mineral resource estimate for its Las Minas project in Veracruz. The report states an inferred resource of 719 K Oz AuEq contained in 10.3 M tonnes @ 2.17 AuEq and total measured and indicated resources of 304 K Oz Au in 4.97 M tonnes @ 1.90 g/t AuEq.


  • Endeavour Silver Corp. and Capstone Mining Corp. entered into an agreement under which Endeavour has the right to explore and mine for precious metals above 2,000 m elevation (meters above sea level, or “mas”) on Capstone’s the Toro del Cobre claim, adjacent to Endeavour’s Calicanto concessions in Zacatecas. Endeavour granted Capstone the right to explore and mine for base metals below the elevation of 2,000 m (mas). The deal was done on the understanding of mineralization zonation in the district, with precious metals mineralization over 2,000 m elevation and base metals occurring below that mark (Note of editor.- This type of deal is not common in Mexico, and reveals a “Think outside of the box” attitude by both companies).
  • Magellan Gold Corp. and Rose Petroleum PLC signed a definitive and binding stock purchase agreement on Magellan’s acquisition of the mineral processing mill operation in San Dieguito de Arriba, Nayarit.

Upon receipt of regulatory approval, Advance will issue Hot Spring Mining, a Mexican based corporation, 1 M common shares. Hot Spring is to retain a 2.5% NSR, of which Advance has the right to buy 1.5% at a rate of CAD$500 K per 0.5%.
  • Dyna Resources Mexico, S.A. de C.V. announced that it has received a favorable ruling with the dismissal by a court in Veracruz of Goldgroup Resources Inc.’s amparo trial challenge to the US$48 M damages award previously granted in favor of Dyna.
  • Orex Minerals Inc. was made aware that Canasil Resources Inc. has been named in a lawsuit brought by Pan American Silver Corp. with the BC Supreme Court, regarding the mineral claims making up the Sandra Escobar project in Durango.

Golden Minerals Announces Drill Program at Mogotes Property and Additional Project Activities


GOLDEN, Colo., Sept. 15, 2017 (GLOBE NEWSWIRE) — Golden Minerals Company (“Golden Minerals”, “Golden” or “the Company”) (NYSE American:AUMN) (TSX:AUMN) is pleased to share a business update, including:

  • 1,500 meter initial drill program at its Mogotes property (Durango, Mexico) is scheduled to start the week of September 18, 2017
  • Dewatering of El Quevar underground workings is planned to accommodate a potential drill program (Salta, Argentina)
  • A re-modeling of El Quevar’s silver deposit resource is underway to identify a potentially economic resource in the core of the Yaxtche deposit
  • Argentina Value Added Tax (“VAT”) refunds received totaling US$1.1 million in second and third quarters of 2017
  • Further to the Company’s September 7, 2017 news release announcing the start of a new drill program at its Santa Maria property (Chihuahua, Mexico), three holes totaling 700 meters have been completed as of September 11, 2017, with drilling ongoing

Golden Minerals President and Chief Executive Officer Warren M. Rehn commented, “We are dedicated to unlocking the full value of our existing resources and infrastructure in Mexico and Argentina.  The drill program at Mogotes is a first test of an extensive altered area that shows signs of being a productive epithermal system hosted in volcanic rocks within a few kilometers of our existing mills at Velardena.  Surface values from channel samples show strongly anomalous gold, arsenic and antimony values associated with hydrothermal breccia veins and silicification along a major fault structure.
