ON MEXICO ISSUES

  • Luca Mining Corp., Vizsla Silver Corp., Questcorp Mining Inc., and Kingsmen Resources Ltd., reported the best drilling intercepts in Mexico on the third week of January, 2026. Details are shown in the table below:

ON EXPLORATION

  • Regency Silver Corp., began its 2026 drill program at Dios Padre project in Sonora. The initial portion of the 2026 drill program will focus on testing the areas around hole REG25-26 with at least four holes between 500-650m in length, which intersected sulphide- specularite supported breccia in multiple zones across a broad, non-continuous ~240m interval. The goal is to systematically establish the dip and strike of the breccia.
  • Colibri Resource Corporation resumed its RC drilling program in El Plomo at its EP project in Sonora. “The current phase of work is designed to systematically evaluate priority structures and targets identified within the Plomo area, which has seen limited historical drilling, using a disciplined, first-pass exploration approach”.
  • Riverside Resources Inc., and Questcorp Mining Inc., announced drill results from La Union project in Sonora. They reported a new discovery of potential Carlin-like gold mineralization at the Luis Hill target, with hole UND-25-009 returning  0.29 g/t Au over 42.70m in black shales and carbonate strata. To date, 12 holes totalling 1,600m have been completed across six targets (Union, Union Norte, and Famosa Mine, as well as Cobre, Luis Hill, and Famosa EM). Assays of over 700 half-core samples are pending for Union, Union North and Cobre targets.
  • Alto Grande Copper Corp., informed that it will use AI-driven data reprocessing and integration across its Adelita project in Sonora. The plan is to analyze geological and geochemical zones to identify skarn zones and areas with Cu-Au and Cu-Mo anomalies; to analyze geophysical datasets to identify potential sulphide mineralization and deep-seated fault systems; reprocess all the historical datasets, ground magnetic surveys, core drilling, trenching, mapping, and geochemical sampling to create a unified 3D geological model to enhance their understanding of mineralization geometry and identifying high-confidence drill targets. The company plans to design a Phase 2 exploration program based on results and logistics, and is expected to commence in Q1, 2026.
  • Masivo Silver Corp., informed that is preparing a 1,500m Phase I drill program at its Cerro Colorado project in Sonora and finalizing logistic to support continuous drilling. It has secured drilling contractors and water supply infrastructure, and mobilized field crews to commence the rehabilitation of access routes to priority targets and construction of drill pads for the Phase 1 program.
  • Kingsmen Resources Ltd., released results from 3 holes drilled at its Las Coloradas project in Chihuahua. The most significant drill intersect was encountered in hole LC-25-004 with 0.08 g/t Au, 131 g/t Ag, 3.1% Pb, and 3.15% Zn over 3.15m, including 0.18 g/t Au, 292 g/t Ag, 7.2% Pb, and 6% Zn over 1.15m.
  • Mercado Minerals Ltd., commenced its first field exploration program at its Copalito project in Sinaloa. It include a detailed mapping and prospecting program across 40% of the project area which remains unexplored; re-sampling of silver, gold, lead, and zinc vein mineralization in selected historical drill core from the six main known veins; re-logging of targeted historic drill core to refine geological understanding; advancing logistics for the upcoming first-phase diamond drill program; and further refinement of drill targets at Copalito.
  • Mithril Silver and Gold Limited commenced a maiden drill program at Target 3 in its Copalquin project in Durango. The program plans to drill approximately 3,300m as part of a broader 25,000m drilling initiative for the district in the first half of 2026. The goal of the Target 3 program is to test the continuity and scale of mineralization, contributing to the understanding of the district’s epithermal system. Drilling at Target 1 and Target 5 is also ongoing, with Target 1 expected to be completed in Q1 2026, followed by an update to its maiden mineral resource estimate. Additionally, a drone magnetic survey over the Copalquin and La Dura mining concession areas is set to begin this month.
  • Pacifica Silver Corp., announced the commencement of a 12,000m Phase II diamond drill program at its Claudia project in Durango, scheduled to begin on January 15, 2026.This follow-up program aims to expand known high-grade mineralization zones identified in the initial Phase I drillings, which totaled nearly 8,000 meters. The company is focusing on testing extensions of existing vein systems such as Aguilareña, Guadalupana, and Veta Central, as well as exploring new high-priority targets including the Veta Justina, Mina Vieja, and Mina de Oro areas. In parallel, Pacifica continues extensive geological mapping and surface sampling, complemented by advanced geophysical surveys like LiDAR, orthophotos, and induced polarization, to identify new drill targets and better understand the district-scale potential of the project. The company is optimistic about the project’s growth potential, supported by early drill results of the 8,000m Phase I program indicating high-grade silver and gold mineralization. The company is still waiting on more assay results from 19 holes of the Phase I drill program.
  • Pinnacle Silver and Gold Corp., provided a progress update for its Potrero project in Durango. The company has mapped a large low-sulphidation epithermal vein system over a strike length of more than 1.6Km, with promising veins confirming a high-grace mineralizing system. It also has collected nearly 1,200 samples and has identified potentially economic grades sowing high grades such as up to 85.1 g/t Au and 2,280 g/t Ag. Metallurgical testing indicates promising gold recoveries averaging around 95%, although silver recoveries require further improvement. The existing processing plant, built in the late 1980s and currently idle, is capable of processing about 100 tonnes per day and will be rebuilt as part of development plans. The company has strengthened its management team with experienced local professionals and is engaging with local communities and government agencies for permitting and social license. Upcoming work in 2026 includes underground delineation drilling, surface drilling to fill exploration gaps, and continued metallurgical and mineralogical testing. Pinnacle has initiated negotiations for permits required for surface and underground operations and is exploring new targets revealed by an airborne LiDAR survey. The company aims to move rapidly toward potential near-term production, build shareholder value, and possibly increase its ownership stake in the project by generating cash flow through initial production.
  • Canasil Resources Inc., prepared drill plans for a 2,450m diamond drill program in 14 holes to test the potentially high-grade Au-Ag epithermal vein at its Vizcaino project in Durango. The vein system can be traced for over 3km with outcrop widths of 1 to 12 m. Canasil will apply for the drill permit and plan to start with a Phase I program with 1,050m in 6 holes as soon as the drill permit is obtained, which is expected in Q2, 2026. At its Salamandra project in Durango, it is conducting a comprehensive technical review and exploration plans and will be applying for drill permits in Q1, 2026. In Zacatecas-Durango, the company is also preparing detailed exploration plans, including diamond drilling to test La Esperanza vein system, and will be applying for the drill permits in Q1, 2026.
