ON MEXICO ISSUES
- The Secretary of Economy, Marcelo Ebrard, stated that the Mexican mining states are the new focus to strengthen the sector and ensure that extracted metals and minerals are transformed into value-added products. The event held in Mexico City was attended by the governors of Sonora, Alfonso Durazo, and Zacatecas, David Monreal, two states with a mining vocation, as well as representatives from academia and the sector, who highlighted the importance of a coordinated strategy between the federal government, universities, and the private sector. The government aims to retain economic and technological benefits domestically through initiatives like the Mexico 2025 Mining Education Committee, which fosters industry-academia collaboration. Specifically, efforts are underway to advance lithium production, particularly in Sonora, with support from federal and state authorities, though some projects such as the Sonora Sustainable Energy Plan are still in exploration phases.
- Marcelo Ebrard, Secretary of Economy declared that mining has become fashionable due to global geopolitical changes, marking a shift from the previous administration’s policies. Ebrard highlighted the need for Mexico to scale up its capabilities in the mining industry, particularly in refining minerals like copper, to support industries like automotive. He emphasized the importance of implementing a policy of will to address challenges in obtaining critical minerals in a world with geopolitical tensions, citing silicon for semiconductors as an example.
- Axo Copper Corp., reported the best drilling intercepts in Mexico on the third week of June 2025. Details are shown in the table below:

ON EXPLORATION
- Axo Copper Corp., initiated a 15,000m phase II drilling program at its la Huerta Copper project in Jalisco. One drill is currently on site and initiating the first drillholes targeting the main La Huerta Trend in an area with a NE-SW strike length of approximately 1km, starting at Las Marias Zone and stepping out to the north along strike towards the Cornelio target. The first hole is expected to be finished in approximately two weeks, with assays being released in the first half of July. In addition, Axo reported that recent exploration efforts, including mapping and sampling, have identified a new area at La Huerta South, approximately 3km from the main Huerta Trend where surface sampling yielded high-grade assay results, with multiple samples returning > 10% Cu, particularly within N-S and E-W fault structures in andesitic volcanic rocks. Sampling along the 1km long N-S structure has returned results such as 7% Cu, 10.8% Cu, and 10.5% Cu, with numerous other showings above 2% Cu, while the approximately 500m long E-W structure returned highlighted values of 3.6% and 2.6%. In both structures Cu mineralization consists of chalcopyrite and bornite hosted in andesites.

The best drill intercepts were encountered in hole JES-24-79 with 0.82 g/t Au and 0.5 g/t Ag over 50.32m, including 0.96 g/t Au and 0.6 g/t Ag over 42.7m, including 10.9 g/t Au and 2 g/t Ag over 3.05m, including 21.4 g/t Au and 3 g/t Ag over 1.52m. “Like the Main Zone, the North Hill trend is exposed at surface along a rounded ridge top, allowing the potential for a low strip ratio during early development. The hole tested near-surface mineralization and was stopped at 125.1m, mineralization at North Hill remains open along trend and to the east.
- Silver Tiger Metals Inc., presented results from its ongoing PFS drilling program at its El Tigre project, Sonora. Hole ET-24-568 collared at the Keel Zone intercepted 6.21 g/t Au and 410 g/t Ag (11.67 g/t AuEq or 876 g/t AgEq) over 16m, including 90.9 g/t Au and 6,034 g/t Ag (171.35 g/t Au or 12,852 g/t Ag( over 1m. The hole passed through the El Tigre vein located some 15m beneath the floor of the PEA Open Pit and is referred to as the Keel Zone. Other new intersections through the Stockwork deposit include holes ET-24-570 with 1.63 g/t Au and 22 g/t Ag (1.92 g/t AuEq or 144 g/t AgEq) over 59.3m; hole ET-23-563 with 0.7 g/t Au and 35 g/t Ag (1.17 g/t AuEq or 88 g/t AgEq) over 45m, including 1.01 g/t Au and 89 g/t Ag (2.2 g/t AuEq or 165 g/t AgEq) over 15m, including 1.43 g/t Au and 634 g/t Ag (9.89 g/t AuEq or 742 g/t AgEq) over 2m, plus 0.68 g/t Au and 2 g/t Ag (0.71 g/t AuEq or 53 g/t AgEq) over 6m; and hole ET-23-552 with 0.83 g/t Au and 6 g/t Ag (0.92 g/t AuEq or 69 g/t AgEq9 over 35.5m, including 2.1m mining void, plus 1.66 g/t Au and 2 g/t Ag (1.68 g/t AuEq or 126 g/t AgEq) over 7m, plus 0.44 g/t Au and 0.5 g/t Ag (0.45 g/t AgEq or 33 g/t AgEq9 over 19.5m. “The results may increase the updated MRE associated with the PFS-level study which we expect to deliver by September 2024, which will also further de-risk the project.” Mr. Jessome (Silver Tiger CEO) continued, “We contemplate being able to make a build decision based on our upcoming PFS.”
- Luca Mining Corp., confirmed new high-grade gold zone with significant mining widths at its Tahuehueto mine, Durango. New geological mapping and sampling at the Main Creston Vein at underground Level 23 confirmed the presence of breccia ore shoots up to 20m wide with some internally assayed channel samples returning greater than 20 g/t Au.

Additionally, expansion drilling targeting the Hanging Wall 4 structure and the recently discovered El Molino Vein, returned significant gold and silver values outboard of the current resource boundary. We are very pleased with how Luisa, Napoleon and Copala are responding to tighter spaced drilling. This supports increased potential for resource conversion as we de-risk the project ahead of the preliminary economic assessment planned for early Q3.”

Prospective veins on the project are hosted within a volcanic caldera setting; the surface extent of mapped veins measuring roughly 4km by 3km. Management believes that Columba may be a newly recognized vein district that is nearly entirely preserved from erosion.
