ON MEXICO ISSUES

Vizsla Silver Corp., provided information regarding a security incident at its Copala project in Concordia, Sinaloa. Ten individuals were taken during the incident. The incident is currently under investigation and information remains limited. As a precautionary measure, Vizsla Silver has temporarily suspended certain activities at and near the site.
According to financial analysts, The 10 largest publicly traded mining companies have registered a gain of USD $528.63 B in the last year. This increase in value is driven by a historic rally in the prices of gold and silver, and sustained demand for copper for the energy transition. The gold price has rebounded by more than 20% so far this year, and the silver price by around 63% in 2026. The 10 largest mining companies reached a combined market capitalization of USD $1.33 trillion as of January 28, 2026. Compared to January 2025, the same companies had a combined market value of USD $678.57B, representing an increase of 96.47% or USD $654.6B. Included in this list is Southern Copper Corporation, one of the world´s largest integrated copper producers, with mail operations in Peru and Mexico, which added USD $88.37B to its market capitalization. In January, 2026, the mining company´s value is projected at USD $162.3B. On the other hand, in the last year, Grupo Mexico became the largest company on the Mexican Stock Exchange by market capitalization exceeding USD $73.46B.

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.

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.

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.
