ON MEXICO ISSUES

  • According to an analysis of SP Global Market Intelligence, the Mexican Mining Policy may affect Mexico-USA Critical Minerals Plan. Mexico is among the largest producers of six of the 60 minerals it imports from the United States, but the 2023 mining reform could limit the attraction of new investment. The agreement on critical minerals recently reached with the United States represents an opportunity for Mexico to boost its mining sector. Despite the agreement, President Sheinbaum has reiterated that no new mining concessions will be granted, nor will the strict 2022 law be modified, which could limit the attraction of new investments and the development of new projects.
  • Minaurum Silver Inc., Silverco Mining Ltd., Heliostar Metals Ltd., Capitan Silver Corp., and Axo Copper Corp., reported the best drilling intercepts in Mexico on the fourth week of February, 2026. Details are shown in the table below:

ON EXPLORATION

  • Barksdale Resources Corp., informed that it is reviewing a sample collection program to assay historic core drill samples and core from 2021 Barksdale drilling program for gold content. During the 2021 drill campaign, Barksdale encountered three broad intercepts of gold, including 1.97 g/t Au over 27m in hole SJ21-04; and two 21m intervals of 0.55 g/t Au followed by 1.57 g/t Au in hole SJ21-05.
  • Riverside Resources Inc., reported new assay results and exploration updates from its Ariel project in Sonora. Highlights include high-grade mineralization from veins in the northern Maria Luisa area, with values of up to 320 g/t Ag, 5.4% Pb, and 0.66 g/t Au. The company also completed detailed geological mapping and alteration mineral studies using spectral analysis to identify minerals associated with porphyry copper and high-sulphidation systems. In addition, a regional geophysical dataset was analyzed to prioritize drilling within permitted areas. Riverside expanded its land position through the acquisition of adjacent mineral concessions, consolidating the Ariel project into a single, drill-ready property covering 1,640 hectares. The work has further refined two principal target styles: a porphyry copper target and an epithermal target interpreted as the upper portion of a porphyry system.
  • Mammoth Resources Corp., identified potential draw point locations for small-scale gold-silver and pilot leach testing at its Tenoriba project in Chihuahua. Geologists analyzed thousands of surface samples and drill results, combined with geological and geophysical data, to pinpoint promising several draw point within the Carneritos area, with average gold grades ranging from about 0.97 g/t to 3.86 g/t. The target that shows high surface grades averaging 3.86 g/t gold has not been drilled yet. Next plans of the company are to carry out a field validation of the selected draw points; estimate size and tonnage; run metallurgical tests, and drill to define resources.
  • Pinnacle Silver and Gold Corp., provided an update on its El Potrero project in Durango, as its progresses towards a production decision. Key developments include the rehabilitation of historic mine workings and the preparation of drill stations, with a a total of 2,423m of drilling across 107 holes planned. The company also has applied for an environmental permit for surface drilling; completed a second round of metallurgical testing to optimize gold and silver recoveries, and finalize a feasibility study to extend a powerline to the project site. In addition, further community agreements are expected following the recent signing of a one-year agreement with the Ejido El Carmen.
  • Mithril Silver and Gold Limited reported progress of its ongoing exploration activities at La Dura and Copalquin projects in Durango. A high-resolution LiDAR survey revealed a 1.5 km by 300m structural corridor with multiple historic mine shafts, adits and prospecting pits, identifying a high-priority key drill target. Ongoing drilling at Target 1 aims to update resources, while promising early results at Target 3 are guiding future exploration. The company is integrating LiDAR, magnetic surveys, and sampling data to prioritize areas for resource expansion and district-wide development.
  • Capitan Silver Corp., released assays from nine RC holed drilled at Cruz de Plata project in Durango., and initiated core drilling at the property, focused on extending the new high-grade silver zone at the Jesus Maria trend proximal to the Peñoles Fault. Two more rigs are expecting to arrive in the coming weeks and will target several priority drill targets in addition to testing deeper mineralization along the Jesus Maria Silver Trend. RC Drilling highlights are shown in the next table:

Mexico Freezes New Mining Concessions

President Claudia Sheinbaum has confirmed that Mexico will issue no additional mining concessions and will instead subject existing permits to an environmental review—cementing the de-facto moratorium imposed by her predecessor, Andrés Manuel López Obrador.

“There is not going to be another new concession—no, there are no new mining concessions,” Sheinbaum told reporters, adding that Environment Secretary Alicia Bárcenas “is working to solve the existing problem of contamination that remains in the mines.”

Mexico ranks as the world’s leading silver producer and a heavyweight in gold, copper, lead and zinc output. Industry lobby CAMIMEX has previously estimated the concession freeze cost …….

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.
