ON MEXICO ISSUES

  • No relevant news.

ON EXPLORATION

  • Colibri Resource Corporation retained CANMEX Perforaciones y Servicios SA de CV to conduct its next phase of drilling at the EP project in Sonora. The program will be focused on the undrilled San Perfecto and Banco de Oro target areas.
  • Kenadyr Metals Corp., provided an update on its Adelita copper-gold-silver project in Sonora. The company is preparing to commence Phase 1 exploration activities, including drilling and detailed geophysical surveys at the Cerro Grande skarn zone, following receipt of all necessary permits, including a 20-year mining license. The deal with Infinitum Copper (80%) and Minaurum Gold (20%) is basically done; just waiting on final TSXV approval, and financing is almost wrapped up with a last tranche expected soon. Overall, the project is positioned for active exploration with long-term development potential.
  • Advance Metals Limited confirmed high grade silver-gold in previously unsampled core at its Yoquivo project. More than 6,300m of unsampled core in the Pertenencia Zone has been identified, representing greater than 50% of the historic drilling completed. First batch of sample results comprising 222.7m of core across 11 holes in the southern portion of Pertenencia Zone has confirmed the untested potential, returning grades of up to 370g/t Ag & 6.2g/t Au. Sampling from holes drilled in 2022 include holes YQ-022-025 with 480 g/t AgEq over 2.05m, including 848 g/t AgEq over 1.1m, and hole YQ-022-002 with 115 g/t AgEq over 4.45m, including 249 g/t AgEq over 0.95m. Multiple additional batches of previously untested core are currently awaiting assay results.
  • Mithril Silver and Gold Limited provided exploration results and an update for multiple targets at its Copalquin project. Target 5 in the southwest area of Copalquin, which is still in the early stages of exploration but showing great promise that could significantly impact the district´s resource potential, returned impressive silver-gold drill intercepts, including a standout hit of 1,714 g/t AgEq over 1m. Drilling highlights include hole AP25-003 with 2.28 g/t Au and 500 g/t Ag (660 g/t AgEq) over 2.75m, including 5.8 g/t Au and 1,308 g/t Ag (1,714 g/t AgEq) over 1m; hole AP25-005 with 1.71 g/t Au and 246 g/t Ag (366 g/t AgEq) over 3.35m, including 5.35 g/t Au and 771 g/t Ag (1,146 g/t AgEq) over 1.05m; and hole AP25-006 with 4.55 g/t Au and 409 g/t Ag (728 g/t AgEq) over 1,25m, plus 2.41 g/t Au and 447 g/t Ag (616 g/t AgEq) over 0.90m, plus 1.51 g/t Au and 321 g/T AgEq) over 0.80m. To date, 13 drilled holes have been completed at Target 5 with assay results received for the first eight holes. On the other hand, channel sampling at Tasolera mine returned high grade results, including 2 g/t Au and 3,300 g/t Ag (3,440 g/t AgEq) over 1.4m. This target is

rapidly emerging as a major silver zone. Only around 5% of the related vein system has been tested so far, meaning there´s plenty more ground to cover. Ongoing exploration mapping and channel sampling is on progress to expand its footprint. At Target 3, preparations are underway for drilling, supported by ongoing mapping and sampling efforts. This target is a large, highly prospective gold-silver zone with multiple high-grade surface samples and extensive mapped veins. At Target 1 (El Refugio-La Soledad), which hosts the maiden JORC mineral resource estimate,  an ongoing drilling program is underway aiming to expand this existing resources by testing its western extensions and deep zones. At Target 6, new targets, including old workings have been identified with some recent sampling and mapping, indicating potential for future exploration. In general, drilling keeps revealing solid gold-silver mineralization, and the company is moving fast with more holes planned in multiple areas of the district.
