Silver Dollar Resources Inc., outlined 2026 plans at its La Joya project, Durango. The company is shifting its exploration strategy from potential open-pit to underground development, focusing on higher-grade underground mineralization. The focus is on targeting higher-grade underground mineralization within the 2 x 3 kilometer La Joya mineralized complex. Key activities include enhanced modeling of known high-grade areas, detailed underground and surface mapping and sampling, and the re-logging of selected historical drill core. The areas of focus include targets that demonstrate similarities to the nearby San Martin mine, known for significant silver mineralization. Five targets are identified for drilling to test for deep San Martin-type mineralization.
Guanajuato Silver Company Ltd., announced its ambitious consolidated drilling plans for 2026 at their five Mexican mine operations (Topia in Durango, and Bolañitos, El Cubo, Valenciana, and San Ignacio in Guanajuato), with a total of approximately 75,000m of drilling expected. This represents significant increases over previous years, specifically 731% more than 2025 and 1,660% more than 2024. The drilling will be divided into 45,000m of exploration drilling and 30,000m of infill drilling, aimed at establishing reserves, enhancing material definition, and expanding resource bases at various mines under its ownership in Mexico. The plan marks a strategic commitment to invest in resource growth and long-term production increases.
Mithril Silver and Gold Limited provided a summary of the Q4, 2025 exploration activities carried out at their Copalquin and La Dura properties in Durango. In 2025, Mithril made significant advancements in exploration activities at the Copalquin district. Throughout the year, drilling at Target 1 expanded the mineralized system and an update of the maiden resource at Target 1 is planned for Q2, following a 3,000m drill program to infill key areas in the mode. Target 5, with multiple, parallel NW trending veins hosted in the granodiorite intrusive in the southwest area of the district emerged as a promising silver-rich growth opportunity. Preparations were made for drilling at Target 3, which commenced in January 2026. On the other hand, additional exploration efforts included systematic mapping, sampling, and geophysical work are currently being carried out to strengthen the geological model across the district. The overall focus on these activities indicates a firm belief in Copalquin’s potential as a large, vertically extensive epithermal gold-silver system with mineralization defined over 9km strike length and 1,200m vertical extent, with multiple targets, a dominant east-west structural corridor, and multiple northwest-trending structures within the 70 square km mining concession area, suggesting a considerable resource growth potential. Finally, the company acquired La Dura mining concessions, which comprise five contiguous concessions totaling 2,052 hectares, located just 5 km from El Durazno and 20 km from the flagship Copalquin property. This area is noted for a significant Au-Ag sheeted to stockwork vein system associated with NW striking faults.

EV Resources finalized plans for a maiden drill program at its Los Lirios project in Oaxaca and reported preliminary metallurgical recovery results. This Phase 1 drill program will consists of 1,500-2,000m and will test high-grade antimony beneath historical old workings along the Lirios Fault Zone over approximately 900m of strike within a broader 4kmmapped system. The drill program is a critical since step as it moves from surface exploration to subsurface definition, targeting a maiden JORC resource in Q3, 2026. It also reported exceptional preliminary metallurgical recovery results with 90.8% recovery established in preliminary metallurgical test work using a simple reagent-free , two stages gravity process, and 99.2% from a high-grade sulphide flotation test followed by regrinding of rougher concentrate and two-stages cleaning.

ON MINING

ON MEXICO ISSUES

The Association of Mining, Metallurgical, and Geological Engineers of Mexico (AIMMGM) expressed its concern about the reform to the Water Law, which according to the miners threatens the operational continuity of the sector, the production of strategic minerals, and the live hoods of approximately 3 million families who depend directly and indirectly on mining. This amendment would allow water concessions to be granted to the mining industry under new restrictions and usage priorities, which could significantly limit or modify their access to and operation of water in areas where the resource is currently used. The association, which represents professionals and technicians in the mining industry, highlighted that currently 76% of Mexico’s water is allocated for agricultural use, 14% for public supply, 5% for the energy sector, and 5% for the industrial sector, and mining uses an estimated 0.27% of the total national volume.

·         In agreement with the Mexican Mining Chamber (CAMIMEX), the Association of Mining, Metallurgical, and Geological Engineers of Mexico (AIMMGM) called for legislation on water resources that balances industrial, social, and environmental considerations, and warned that potential negative impacts could arise from proposed changes to article 118 of the National Water Law. It also stated that efficient and responsible water management is a fundamental pillar of sustainable development strategies for economic activity in Mexico and that human consumption should be prioritized. However, the proposed reform would negatively impact the mining industry and other economic sectors.  “Formal mining in Mexico adheres to strict standards and safely contains its waste. With guidance from federal agencies such as the National Water Commission (CONAGUA), mining units establish clear guidelines for the responsible management of water resources, guaranteeing their preservation and sustainable use during the operational phase and after the conclusion of mining activities. The AIMMGM reaffirmed its willingness to collaborate with the Government of Mexico in building an effective, sustainable regulatory framework that is fully aligned with national objectives for mining.

Pan American Silver Corp., provided a 2025 year end exploration update on its La Colorada mine in Zacatecas-Durango. In 2025, the company drilled nearly 23,000m to expand its mineral resources. The company particularly focused on the eastern and deeper parts of the mine, where recent drilling confirmed high grades of silver, gold, lead, and zinc, and extended mineralization beyond current resource estimates. A key highlight was the success in exploring the eastern extensions of high-grade veins, especially along the NC2 and Mariana vein systems. These efforts have helped increase the estimated inferred silver mineral resources to about 52.7M Oz in all mineralization styles, thanks to new discoveries and resource expansion campaigns. Overall, the focus is on enhancing the existing resource base and exploring new zones to sustain long-term production.
Torex Gold Resources Inc., released drill results from Media Luna West in its Morelos Complex in Guerrero. “A mineralized footprint of 400 x 300 m has now been defined.
