ON MEXICO ISSUE

  • Members of the Mining Cluster of Chihuahua met with federal deputies of the Partido Acción Nacional (PAN) to let them know of the importance of mining not only in the state but in the entire country. Deductions of the mining exploration expenses as well as the electricity reform were some of the issues addressed to the deputies. According to the mining sector, if the electricity reform is approved, it will affect the competitiveness of mining. The Mining Cluster, in communion with government authorities, seeks to generate the development of local supply, as well as attracting greater mining investment in the state.
  • President AMLO announced a proposal that would put end the current system of lithium concessions and leave exploration and production in the hands of the State. However, the owner of the USD $420M project Bacanora Lithium stated that the Mexican government’s plans to bring lithium resources under state control will not affect progress in Sonora, since the new reforms will not affect lithium licenses already granted to private companies, as long as exploration work has already started and all licensing requirements have been met.

ON EXPLORATION

  • One World Lithium Inc., provided an update of its current drilling program at its Salar del Diablo project in Baja. The company announced that hole DDH-4 reached a depth of 381m on October 2, 2021 with an expected total depth of 600m. If the results of DDH-4 warrant it, other boreholes will be drilled in the area.
  • Benjamin Hill Mining Corp., provided an update of details on the recently released NI 43-101 report on its Benjamin Hill project in Sonora. “Detailed mapping at 1:1,000 scale has indicated the presence of a large magmatic-hydrothermal system, including mineralized structures, stockworks, sheeted veins, alteration halos, all of which are hosted in granitoids, an eroded skarn system, a volcaniclastic sequence, and volcanic rocks, as well local orogenic quartz veins. This large hydrothermal system could be co-genetic with a bimodal dike swarm mapped on the property and related to a buried fertile plutonic system, suggesting that geological structures and mineralization seen at surface are indicative of a Cu-Au porphyry system at depth”. Recommended activities to be conducted at the property over the next 2-3 months are completing the mapping and sampling on the areas of Caracahui, la Salada, Caracahui Norte and the Sonora Copper; mapping and channel sampling of the Cascabel and Guadalupe adits; dating studies of the plutonic rocks, prospection of the new areas generated by geochemistry (La Falsa, San Felix, and La Berrenda); and channel sampling on the Sonora Copper adit.
  • Almadex Minerals Ltd announced Q4, 2021 plans for its San Pedro project in Jalisco. The company reported that the property is fully permitted and is currently mobilizing a team and rig to site to conduct a drill testing prior to year-end.
  • Kootenay Silver Inc., reported results from the last six holes collared at its Columba project in Chihuahua. The company announced the best drill intercept to date in hole CDH-21-103 with 333 g/t Ag over 44m, including 805 g/t Ag over 17m, including 1,201 g/t Ag over 11m, including 2,035 g/t Ag over 6m, and a high of 9,840 g/t Ag over 0.92m.

While the Company continues to proactively engage CONAGUA to expedite the permitting process, the operating assumption is that a permit will not be forthcoming and numerous longer-term solutions are currently being assessed, including processing ore at third-party facilities”.
  • McEwen Mining Inc., reported Q3, 2021 production results from its El Gallo property in Sinaloa. In Q3, El Gallo produced 560 Gold Equivalents Ounces (GEOs) from residual leaching of the heap leach pad.
