ON RESOURCES AND DEVELOPMENT

  • Impact Silver Corp., released underground drill results from the Santo Domingo Zone at its Plomosas mine in Chihuahua. Assays results are shown in the table below.

Guanajuato Silver Company Ltd., announced high-grade gold intercepts at its Valenciana mine complex in Guanajuato. Drilling results are presented in the table below:

  • Agnico Eagle Mines Limited advanced in Q2, 2025 its Feasibility Study on San Nicolas project, Zacatecas, which remains in schedule to be completed by year-end. San Nicolas is 50/50 joint venture with Teck Resources Limited. The company also announced that it received an exploration permit authorizing additional drill pads across the property, and reported that Minas San Nicolas approved an USD $8.8M budget to conduct drilling activities focused on geotechnical, hydrological, and geological evaluation in proximity to the projected mine area.
  • Tocvan Ventures Corp., received permit for all drilling, trenching and extraction at Gran Pilar project, Sonora. The permits allow for 45 new drill pads enabling over 30,000m to expand resources and enhance the geological model as well as to explore high-grade target zones. It also includes 67 trenches across Gran Pilar for exploring and extraction of material for pilot mine. It pushes the company closer to running a 50,000 tonnes pilot mine development, refining their resource estimates, and to support its goal of advancing towards production.
  • Kootenay Silver Inc., finalized its first mineral resource estimate for the Columba Project in Chihuahua. A total of 17 epithermal veins that comprise the Columba vein system were included in the Mineral Resource Estimate (MRE). They’ve identified, at a base-case cut-off grade of 150 g/t Ag, inferred mineral resources of 5.92M tonnes grading 284 g/t Ag, 0.2% Pb, and 0.50% Zn. The MRE includes inferred mineral resources of 54.1M Oz Ag, 25.2 M Lb Pb, and 65.6M Lb Zn. The MRE is exclusive of mined out material (F Vein). Kootenay also mentioned that they´ve started a new phase of drilling to expand these mineralized zones even further.
  • Mithril Silver and Gold Limited reported significant high-grade results from channel sampling at its Copalquin property in Durango. Highlights include Target 6 with high-grade assays from channel sampling at the historical Santa Cruz underground mine, with notable results including 0.70m of 57.8 g/t Au and 2,120 g/t Ag; 0.80m of 17.4 g/t Au and 603 g/t Ag; 0.50m of 8.42 g/t Au and 188 g/t Ag; and 0.70m of 23.2 g/t Au and 755 g/t Ag; and Target 5  with surface channel sampling returning 0.5m of 27.9 g/t Au and 14 g/t Ag; 0.30m of 9.6 g/t Au and 608 g/t Ag. The mineralized corridors now cover an area of 2 km x 8 km with an elevation profile of 1,200 m within the 70 km² mining concession area. Mithril is fully funded to complete 45,000 meters of drilling over the next 12 months, with plans to commence drilling at Target 5 in mid-August 2025. 5. The results from both Targets 5 and 6 indicate a significant high-grade potential in the Copalquin District, which is developing into a notable gold-silver district in Mexico’s Sierra Madre trend. These highlights reflect the ongoing exploration success and the promising future of the Copalquin property.
  • Vizsla Silver Copor., and Vizsla Royalties Corp., announced preliminary results from a regional HLEM geophysical survey and initial fieldwork across its Panuco mining district and newly acquired Santa Fe property in Sinaloa. The HLEM survey at Panuco identified new near-surface anomalies including Santa Fe property, and supports resource expansion on known structures and proximal targets in Panuco West. Resource extension targets include Copala, Napoleon, HW4, La Luisa, and La Cruz Negra, each with potential for expansion through further drilling. Key exploration objectives for 2025 include completing +25,000 meters of drilling by the end of 2025, a TEM survey, district mapping, and generating near-mine drilling targets at Santa Fe. They’re focused on expanding their current Project #1 resource and hunting for a new major target, Project #2, using a range of techniques including drilling, mapping, and electromagnetic surveys. The work aims to better understand the structures controlling mineralization and identify fresh high-grade zones, especially around the Copala and Napoleon vein corridors. Their exploration focuses on structural controls such as NW-trending faults and vein corridors like Copala and Napoleon, which influence mineralization. The Santa Fe property’s infrastructure and prospective geology are expected to complement their ongoing district-wide exploration efforts. The Colorada-Napoleon intersection is a conceptual target supported by AI analysis and HLEM anomalies. 4 de Mayo shows high-grade silver intercepts, with HLEM geophysics identifying anomalies for follow-up drilling. San Jack and San Peter are parallel structures with quartz veining and hydrothermal alteration, with HLEM anomalies defining conductor anomalies over these targets. La Pipa is a high-grade shoot along the Animas vein system, with plans to drill +8,000 meters to follow up on the discovery. Camelia-San Dimas, San Fernando-Nacaral, El Roble, Oregano and La Wicha, and Jesusita-Palos Verdes are notable targets for testing. The San Enrique prospect comprises titled mining claims between Panuco and Santa Fe. LiDAR and airborne magnetic surveys show strong NW-trending lineaments, indicative of regional faults. Multispectral satellite imagery and a LiDAR survey will assist during target generation, with regional mapping and stream-sediment geochemistry planned. The La Garra-Metates District constrains silver-gold-rich epithermal veins. Rock chip samples returned silver equivalent grades greater than 200 g/t. The district holds strong potential for discovering high grade mineralization.
  • Gold Resource Corporation released H1, 2025 drill results from its Don David gold mine in Oaxaca, and reported operational improvements. Drilling highlights are shown in the table below:

In addition, Gold Resource has implemented several operational improvements at Don David Gold mine to enhance efficiency and productivity. The Company engaged Cominvi Servicios S.A. de C.V. for accelerated development, completing over 1,350m of underground work. New cut-and-fill mining methods were introduced to enhance grade and returns, alongside the ordering of a third dry stack filter press to boost processing throughput. A comprehensive review of the process plant is underway to optimize reagent use, which is expected to improve recoveries and increase the amount of payable metals. Initial trials have already shown promising results. These improvements are aimed at increasing operational efficiency, reducing costs, and maximizing shareholder value while integrating the newly defined vein systems into the mine’s short-term production plans.

ON DEALS AND CORPORATE ISSUES

ON MEXICO ISSUES

  • Vizsla Silver Corp., announced that it has resumed all field work activities at its Panuco project in Sinaloa due to improvement of the security conditions in the region. Ongoing programs include test mine development, geotechnical drilling, exploration drilling, mapping and geophysical surveys.
  • Carlos Pavón Campos, leader of the Miners’ Union “Frente”, asserted that the USD $55M in question belongs to the workers, confirmed by a recent ruling against the union led by Napoleón Gómez Urrutia. Pavón who worked with Napoleón Gómez Urrutia point out that the judicial process has removed Grupo Mexico and Scotiabank from the trust, leaving the responsibility solely with the union. He highlighted that the ruling mandates the union to cover any payment discrepancies for workers who received between MXP $60-80K. He also mentioned that the three emblematic strikes, which have lasted almost 18 years, are no longer effective. In Cananea, workers have returned to work and many have already been paid. In San Martín, Zacatecas, most have also returned to work, and in Taxco, Guerrero, the company had requested the termination of the collective bargaining agreement due to the lack of mineral reserves. Pavón emphasizes that the workers still waiting to return are in a precarious situation, as the mine has no reserves and many of the original workers have aged or passed away.
