ON MEXICO ISSUES
- Mexico is to review the proposed bill to ban open pit mining, announced Claudia Shienbaum, Mexico’s president. The proposal was approved by the lower chamber of Congress in August, and also seeks to prohibit fracking and restrict water usage in areas of scarcity. She emphasized that the review will focus on ensuring environmental protection and is independent of corporate interests. “The Mexican Mining Chamber (Camimex) has voiced strong opposition to the proposed ban. Open-pit mining accounts for 60% of the value of Mexico’s national mining and metallurgical production. Camimex warns that the prohibition could lead to a 1% contraction in the country’s GDP and jeopardize nearly 200,000 jobs.”
ON EXPLORATION

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.
