The Mining and Exploration News in Mexico: Highlights on the Fourth Week of October, 2021

By Jorge Cirett

During the 43rd week of the year (October 25th to October 31st, 2021), at least 34 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, six released Q3 reports, one on commencement of mining and one other in red tape issues, there were no financing related news, while ten companies posted on project development or resource definition and one more on a project acquisition. ON MEXICO ISSUES, a leftist senator asked for the Mining Fund to be reinstated for the benefit of communities. The head of the Energy Secretariat confirmed plans to create a lithium State company, and the government’s drive to monopolize the electricity market. Mixed market results for Mexican companies in 2021. ON EXPLORATION, In Sonora, Colibri Resources updated on drilling preparations. In Chihuahua, Reyna Silver has drilled the first skarn intervals in the Guigui project, rising the stakes and probing that pursuing geological models can pay off. Radius Gold released good drill results from the California target in the Amalia project. In Durango, Silverton updated on exploration activities at Pluton. In Sinaloa, Brigadier Gold released trench results from El Placer vein system at its Picachos property. In Nayarit, Sierra Madre Gold and Silver released surface sample results.   ON MINING, Fortuna Silver is awaiting a resolution on an application to continue mining at San José, in Oaxaca. Agnico Eagle, Altaley Mining, Guanajuato Silver, Alamos Gold, Coeur Mining, Gold Resource and Fresnillo PLC presented their Q3 2021 reports. Guanajuato Silver shipped its first concentrate from El Cubo mill. ON FINANCING, for the first time in a long period, no relevant news on this matter. ON RESOURCES AND DEVELOPMENT, Sonoro Gold plans a 10,000 m RC drilling campaign alongside the development of a 15 K tpd leach mining operation at Cerro Caliche in Sonora. A PEA has been filed. Barksdale Resources released good drilling results from San Javier, in Sonora. SilverCrest Metals continues construction on budget and on schedule at Las Chispas, Sonora. Excellon Resources presented high-grade drilling results from Platosa, in Durango. Silver Dollar is preparing for drilling at La Joya, Durango.

Advance Gold filed a patent for lithium extraction from clays and fine sands. ON SOCIAL RESPONSIBILITY, Fresnillo PLC informed on health campaigns in Zacatecas.

ON MEXICO ISSUES

  • Geovanna Bañuelos, senator by the Partido del Trabajo (PT) asked for the Mining Fund to be reinstated in benefit to communities and municipalities where mining takes place.
  • Rocío Nahle, head of the Energy Secretariat, confirmed plans to create a lithium State company, as part of a wider reform in the electricity industry, same that is seen as containing expropriation streaks. The private sector is overwhelmingly against this reform, that is seen to conduct to higher energy prices and pollution, as well to scare other investments from the country.
  • Mixed results for Mexican Mining companies reflect changes in metal prices. Companies that have seen their stock tumble during 2021 include Fresnillo (-20.7% in Mexico, -18.3% in London). Peñoles (-11.4%) and Frisco (-4.2%) by their exposure to precious metals that have contracted by 5% in the case of gold and 7.4% for silver. Companies that have seen their stock appreciate include Autlán (+23.5%) and Grupo Mexico (+13.5%), the latter due to the 26.7% increase in the copper price.

ON EXPLORATION

  • Silverton Metals Corp. updated on the exploration activities at the Pluton project in Durango.

Permitting is underway for a seismic test line scheduled to be surveyed before year end. The seismic profile is expected to determine the depth to carbonate rocks” which might determine the depth to the favorable carbonate rocks.
  • Brigadier Gold Ltd. released results from additional trenches at El Placer Sur vein system at its 3,954-hectare Picachos project in Sinaloa.

  • No relevant news.

ON EXPLORATION

  • Benjamin Hill Mining Corp (BHM), confirmed the presence of gold and copper mineralization at depth from channel samples collected underground in the Guadalupe and Cascabel adits at its Sonora Gold project. Highlights of the underground  samples collected over 2m intervals in the Guadalupe adit include 9.6 g/t Au and 0.5% Cu; 8.4 g/t Au and 0.3% Cu; 0.4 g/t Au and 4.3% Cu; 0.3 g/t Au and 3.5% Cu; and 0.2 g/t Au and 2.1% Cu. Highlights of the underground  samples collected over 1.5m interval in the Cascabel adit include 7.7 g/t Au and 0.4% Cu; 2.2 g/t Au and 0.4% Cu; 2.2 g/t Au and 0.7% Cu; 1.5 g/t Au and 2.9% Cu ; 1.3 g/t Au and 2.5% Cu; and 0.8 g/t Au and 2.4% Cu. Highlights of composites of channel samples from the underground sampling were calculated and include 1.54 g/t Au, 0.41% Cu, and 27 g/t Ag over 14m; 1.82 g/t Au,  0.88% Cu, and 44 g/t Ag over 7.5m; and 0.83 g/t Au, 0.38% Cu, and 19 g/t Ag over 7.5m. “The results of the underground sampling program proves that surface gold and copper mineralization extends to depth and supports BHM´s model of a copper-gold epithermal system. BHM geologists have previously mapped copper-gold mineralized structures over 8km cumulative length often attaining widths of 10´s of meters. The results of the adits sampling work supports the rational that the mineralized structures are drill ready targets”.
