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.

- Heliostar Metals Ltd., and Torex Gold Resources Inc., reported the best drilling intercepts in Mexico on the second week of October, 2025. Details are shown in the table below:
ON EXPLORATION
- Tocvan Ventures Corp., reported the early results from a drone magnetic survey at its Gran Pilar Gold-Silver project in Sonora, and announced the discovery of a new target with historic underground workings in the North Alteration Zone.. The survey uncovered a major structural complex in the South Block, spanning approximately 2 by 2.5km. This complex exhibits magnetic signatures suggestive of magmatic activity and correlates strongly with past sampling up to 21.2 g/t Au and over 2,000 g/t Ag. These findings highlight new and expanded exploration targets, especially near areas with historical placer mining, and support the potential for deeper mineralization. The survey results validate geological models and provide a clear pathway for upcoming drill programs to evaluate the project’s mineral resources further. Tocvan also reported that it uncovered a new mineralized zone with 80m exposed section of old underground workings within the North Alteration Zone, with waste piles of silicified vein breccia material, and intense phyllic and argillic alteration. This zone features historic underground workings and extensive alteration patterns of approximately 3.2km long, indicating significant mineralization potential. Initial sampling has returned promising high-grade results for gold and silver, and the company plans to conduct further trenching, detailed mapping, and drilling to explore this largely underexplored area.
- Pacifica Silver Corp., identified new high-priority drill targets based on assay results from 325 surface rock chips samples collected at its Claudia project in Durango. These samples yielded results up to 23.6 g/t Au and 480 g/t Ag confirming that the high-grade Au-Ag mineralization at the property is more extensive than previously recognized and may extend further south for another 300m towards the Mina de Oro vein system. Rock chips sample highlights include 111.2 g/t Au and 17 g/t Ag; 7.15 g/t Au and 143 g/t Ag; 2.74 g/t Au and 404 g/t Ag; 3.33 g/t Au and 311 g/t Ag; 2.03 g/t Au and 312 g/t Ag; 0.39 g/t Au and 408 g/t Ag; 1.83 g/t Au and 230 g/t Ag; and 2.19 g/t Au and 190 g/t Ag. The areas around Veta Justina and Mina Vieja are now considered new high-priority targets for drilling. The company also commenced a Phase I drill program, which aims to delineate and expand known mineralization at the northern extension of the Aguilareña, Guadalupana, and Veta Central veins and to drill high-priority, previously undrilled targets at the Mark Twain, Veta West and Veta Justina areas. To date it has completed 647m of drilling across the first three holes. Pacifica Silver plans to apply for permits to drill new targets as part of the program.

ON RESOURCES AND DEVELOPMENT
- Southern Silver Exploration Corp., initiated a drilling program at the Puro Corazon mine, which is adjacent to its 100% owned Cerro Las Minitas project in Durango, Mexico. Current development at the mine extends for approximately 200m laterally and to 250m below surface. The exploration program aims to integrate the nine-hectare Puro Corazon claim into the larger project and includes up to 12,000 meters of core drilling using three drill rigs. Drilling will test the further projections of the mined mineralization both laterally for an additional 200m and to depths of up to 450 metres below surface where the mineralization then transitions across the claim boundary and into the modelled Skarn Front deposit. Drilling will also target the projection of up to six hangingwall structures identified outboard of the main mineralized Skarn Front zone which was previously identified in both historic drilling within the Puro Corazon claim and in Southern Silver’s own drilling outside the claim boundary. The program will also compile existing geological data, conduct new sampling in historic underground workings, and perform a LiDAR survey to assess the extent of underground mining. Currently, the Puro Corazon mine is privately operated, producing approximately sixty tonnes of ore per day, generating silver-lead and zinc concentrates. The drilling will target lateral projections of mineralization and depths of up to 450 meters below the surface, focusing on six identified hangingwall structures. Results from this drilling will be incorporated into an updated Technical Report and Preliminary Economic Assessment (PEA) scheduled for the first quarter of 2026.

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of September, 2024

Vuggy Silica
By Miguel A Heredia
During the 39th week of the year (September 23rd to September 29th 2024), at least 28 press releases were announced by companies working in Mexico, and 7 news published by the media, with nine disclosing deals and corporate issues, eight announcing financing rounds, eight commenting on Mexican issues, three reporting resources and development of their properties, three communicating production and financial results, three informing on exploration results, and one discussing social issues.

ON MEXICO ISSUE
- The marine exploration company Odyssey Marine Exploration, in which Carlos Ancira, the former president of Altos Hornos de México S.A.B. de C.V., had a shareholding, won an arbitration from the Mexican government protected by NAFTA/TW investor protection. The company was seeking damages in the amount of just over USD $2.3 B and what was finally achieved after the lawsuit was USD $37.1M. The former president of Altos Hornos bought a shareholding in Odyssey for USD $3M in 2015 through his investment vehicle´s Epsilon. The intention of Ancira and its partners was to dredge the seabed of the Gulf of Ulloa, Baja California, on the north Pacific Coast. To extract phosphate, an input used to manufacture fertilizers, a business to which the businessman was dedicated through its firm Agronitrogenados, sold at an extra cost to PEMEX, a scandal that kept the former president of the oil company Emilio Lozoya in jail. Unfortunately, it is a victory that Ancira could not savor, who in September 2021 sold his shareholding in Odyssey, in part to raise the money he promised as a reparation agreement to the Mexican government (in favor of PEMEX) for the Agronitrogenados operation, cause for which he was even detained in the North Prison of CDMX.
- Andrés Manuel López Obrador (AMLO) expropriated from Vulcan Materials a port and a quarry in Quintana Roo, which deepened tensions days before he leaves office. The government of Mexico declared the land south of Cancun and Playa del Carmen as a protected natural area via decree in the Official Gazette of the Federation, this a few hours after US legislators sought to dissuade such a measure. Vulcan´s shares fell 1.03% to USD $249.73 during the morning of September 24, 2024. Vulcan had previously said the AMLO´s government actions are illegal and that it would add the latest measures to an ongoing arbitration case in the International Center for Settlement of Investment Disputes of the World Bank. It marks another movement by AMLO (a staunch nationalist) against private business. A new congress with a supermajority of Morena and allies in both chambers began its term last September and since then they have approved a reform of the Judiciary that has raised fear among capitals in Mexico. Claudia Sheinbaum, who will takes office on October 1, 2024 has not publicly commented on the Vulcan issue since her landslide victory, but a year ago said she hoped the company would accept AMLO´s offer to buy its land for MXP $6,500M. Last year, Vulcan sought intervention from Joe Biden administration against what it saw as the threat of a government takeover of the Riviera Maya property. It said that a valuation made by the Mexican government deeply undervalued the assets. On September 23, 2024, a bipartisan group of US senators proposed legislation to pressure Mexico to retract its expropriation plan. Vulcan is not the only foreign company that has sought legal recourse after government intervention. In December, Mexico took control of operations of a hydrogen processing plant owned by French industrial gases maker Air Liquid. Last year, AMLO announced plans to buy USD $6B worth of energy assets from Iberdrola after the Spain Company faced political hostility from Mexico that affected its permits and supply. AMLO also ordered the cancellation of projects including an airport and a brewery plan during his term. The US ambassador to Mexico, Ken Salazar, warned that companies may lose confidence in Mexico as an investment destination as a result of the judicial reform promoted by congress this month. The change eliminates a check on government power by making federal judges democratically elected, including in the Supreme Court of Justice of the Nation (SCJN).
- Andrés Manuel Lopez Obrador (AMLO), in a last surprise “play” before concluding his mandate fulfilled his warning and finally took control of a port and a quarry owned by the American company Vulcan Materials, with which maintains a dispute for several years now. On September 23, 2024, the head of the executive published a declaration of a protected natural area of an area of more than 53,000 hectares south of Cancun and Playa del Carmen, where the land occupied by Vulcan and an open pit mine of the foreign company are located, dedicated to the extraction of limestone through its subsidiary Calizas Industriales del Carmen (Calica). Vulcan said in a statement that the expropriation of the land and port owned by the company is another escalation and constitutes a new violation of Mexico´s commitments under North American trade agreements, and added that this illegal measure will have a chilling and long-term effect on trade and investment relations between USA and Mexico.
- AMLO concludes his government with the expropriation of the land and port of the Calica mine, property of the American company Vulcan Materials Company in Quintana Roo, involved in a conflict that has kept it without operations in Mexico for three years. The announcement of the expropriation is not a good sign to attract investment to Mexico and could damage business confidence. In the decree published last September 23, 2024 in the Official Gazette of the Federation, the Mexican government justifies its decision by citing the fourth article of the Constitution in its fifth paragraph, which establishes that “every person has the right to a healthy environment for their development and well-being, so the State will guarantee respect for this right.” Furthermore, it invokes article 27 of the Constitution in its third paragraph, which states that “the nation will at all times have the right to impose on private property the modalities dictated by the public interest.” The decree of the federal Executive declares a protected natural area the area located south of Cancun and Playa del Carmen, where the Vulcan lands are located under the Sac-Tun firm (formerly Calica). The measure is intended to prevent the construction company from extracting limestone from the land it owned for decades and which the AMLO government previously tried to acquire without success. The American company not only considers the expropriation of its investments in Quintana Roo illegal, but also warns of a direct conflict with provisions of the T-MEC. The reason is that the investment chapter of the Treaty between Mexico, the United States and Canada states that “no party shall expropriate or nationalize a covered investment, either directly or indirectly through equivalents to expropriation or nationalization,” except in the following cases: For reasons of public utility; in a non-discriminatory manner; through the payment of prompt, adequate and effective compensation, and in accordance with due legal process. The investment chapter contains provisions on expropriation and compensation, which must provide investors with certainty that their properties and positions will be respected, and guarantee non-discriminatory treatment and prompt, effective and adequate compensation, in cases where that their rights are substantially affected by the actions of the State. According to experts consulted, the Calica issue is very serious, since there are no precedents for similar cases since NAFTA. Although expropriation is not a good sign to attract investment to Mexico and can damage business confidence, this week two large American companies confirmed investment announcements in the country totaling USD $2.9 B.
- Metal prices hit highs and boost mining companies in the stock market, with the price of silver rising to its highest level in almost 12 years, taking advantage of gold’s rally to all-time highs, as interest rate cuts from Major central banks fueled investment interest in precious metals. Silver futures rose 0.91% on the Chicago Stock Exchange, to USD $32.31 an ounce, after reaching their highest since December 2012, of USD $32.71. Spot gold rose 0.5% to USD $2,670.52 an ounce, having hit an all-time high of USD $2,685.42 earlier in the day. US gold futures for December delivery advanced 0.39% to USD $2,694.9. Copper prices rose to their highest level in nearly 16 weeks, boosted by hopes of firmer demand for metals after China announced fiscal stimulus measures following an easing of monetary policy to boost its sluggish economy. Three-month copper on the London Metal Exchange (LME) broke the psychological level of USD $10,000 per metric ton, touching the highest level since June 7. This Thursday it gained 3.53% to USD $10,084. The securities of the main mining companies operating in Mexico led the gains in Thursday’s session (September 24, 2024) on the Mexican Stock Exchange. The securities of Grupo México and Industrias Peñoles rose 4.18 and 4.23%, respectively. Shares of Grupo México, an industrial conglomerate with interests in the mining and rail transportation industries, are trading at MXP $112.68, their highest level since May 21, 2024. The shares of Industrias Peñoles were quoted at MXP $292.35, their highest level since April 19, 2024. Meanwhile, Fresnillo shares on the BMV rose 21.69%, while those listed in London advanced 2.74 %. With Thursday’s movement, Grupo México gained MXP $35,655M pesos in market capitalization, going from MXP $842,026M to MXP $877,681M in one day. Industrias Peñoles gained MXP $4,714M in market value, going from MXP $111,488M to MXP $116,202M.

ON MEXICO ISSUE
- Rafael Rebollar, general director of Industrias Peñoles, declared that the mining industry in Mexico has been affected due it awaits response on environmental permits that must be granted by the federal government for tailings deposits, a system that collects all the waste from the mining process, once the waste has been separated from minerals. Failure to grant it could lead to the suspension of operations of some mining units. For his part, Carlos Pavón Campos, general secretary of the Mining Metallurgical Union FRENTE, said that mines throughout the country face restrictions on tailings dams, which represents a risk. He cited the case of Fresnillo and Velardeña as an example. He commented that in Velardeña, there are around 600 unionized workers and that a fundamental part of the mines are the tailings dams.
- The Government of Mexico is preparing a preliminary report with arguments to declare that Vulcan Materials’ Calica mine in Quintana Roo is located within a “protected natural area”, which represents a possible expropriation of its land. The report will be evaluated for 30 days by the governments of the state of Quintana Roo, as well as by social organizations, indigenous communities and universities, reported the Secretariat of Environment and Natural Resources (Semarnat) in a statement sent on Thursday. Vulcan Materials said in May that it received an offer from the Government of Mexico that “substantially undervalues” its property. According to Andres Manuel Lopez Obrador, the Administration offered to buy the firm’s assets on the Caribbean coast for USD $2B. Last May, U.S. senators warned that Mexico’s expropriation of Vulcan land would force them to consider “all available resources” to prevent “the theft of this property,” according to a letter officials sent to the Mexican Foreign Minister Alicia Bárcena.

ON MEXICO ISSUES
- This Sunday June 2nd presidential polls are to be held in Mexico, same that will define the bearing the country is to follow in the next six years and probably beyond that. At stake are the centralized government system with unrestricted power to the presidency sought by the current incumbent Andres Manuel Lopez Obrador, and the checks and balances system between the different government branches (executive, legislative and judicial) sought by the coalition opposition parties. Besides the obvious influence on the economy, if the officialism party´s Claudia Sheinbaum candidate wins, expect a tight grip on the mining industry from the open supporter of socialist economies, like Cuba and Venezuela.
- Nearshoring and electrical vehicles present an opportunity for copper producing Sonora, according to David Ramos Félix, president of the local AIMMGM chapter in the State that produces more than 70% of the red metal in the country
- Restrictions brought by the new Mining Law approved by Fast Track procedures in May of 2023 have delayed the investment of more than US$4.5 billion, according to Karen Flores, president of the Cámara Minera de México (CAMIMEX). The freezing of at least 220 environmental permits is hindering the investments that could generate employment to close to 50 thousand families, with salaries in the metallic mining sector that are 85% above the national average.

- Centenario Gold Corp. announced the next phase of exploration on the Eden property in Sinaloa. The geological team lead by Alain Charest and Hermilo Mendoza outlined several new targets to drill-test across the Eden property, including the northern extension, the upper and deeper portions of the Buenavista epithermal vein system and other sub-parallel mineralized structures, especially the La Proveedora prospect 1.5 Km east of Buenavista. “The upper 100 meter portion of the Buenavista structure extends directly down dip from where the high grade Au and Ag surface sample as high as 239.9 g/t Au and 1390 g/t Ag were obtained”. Quartz textures and alteration minerals at 250 m depth are interpreted as part of the upper level of the epithermal systema, enhancing the probability of further mineralized zones at depth.
