ON MEXICO ISSUES

  • The United States government requested the installation of the first United States – Mexico – Canada Agreement (USMCA or T-MEC) labor panel under the Rapid Response Labor Mechanism (MLRR), for disagreeing with the Mexican government on the complaint against the San Martin Mine, of Grupo México, located in Zacatecas, who is accused of having impeded free unionization and authentic collective contracting. The Mexican government, for its part, responded that it would not review the case under the T-MEC mechanisms, arguing that the conflict dates back to 2007 (since the T-MEC entered into force in 2020) and that there is no evidence of that the mine exports to the United States, so it would not be a facility covered by the treaty. Grupo Mexico denounced that the union leader Napoleón Gómez Urrutia, presented the complaint that gave rise to this process with two objectives: “to have a new pretext to ignore the definitive award that condemns him to pay USD $55M plus accrued yields from 2005 to former mining workers and generate conflicts to press for a new political position that gives him jurisdiction / political privileges (“fuero politico”). After the lifting of the strike, in 2018, San Martin has received investments of more than USD $105M, has produced more than 1.25M tonnes of mineral each year and has generated about 1,300 jobs.
  • USMCA panel analyzes whether there was a violation in the case of the San Martin Mine, Zacatecas of Grupo Mexico. Given these facts, Grupo México indicated that it is essential for the San Martin Mine to put an end to a conflict that has harmed workers and their families for the last 15 years. Grupo México assured that the conflict in the San Martin Mine is not the product of the disagreement of the workers, but of the senator for Morena Napoleón Gómez Urrutia, who presented the complaint that gave rise to this process. “Urrutia sought to have a new pretext to ignore the final award that condemns him to pay USD $55M plus accrued income since 2005 to former mining workers, as well as generate conflicts to press for a new political position.
  • The president of the Business Coordinating Council (CCE), Francisco Cervantes pronounced on the request for a labor panel of the T-MEC in a mine of Grupo México. At the request of the United States government for the first panel of the Rapid Response Labor Mechanism under the Treaty between Mexico, the United States, and Canada at the San Martin mine of Grupo México, in Sombrerete, Zacatecas, Francisco Cervantes Díaz, president of the CCE, commented that it is a panel that has already lost a labor part here, that is why they are entering the issue in the United States and the resolution must be waited for. The Ministry of Economy indicated that Mexico rejected the request because this conflict dates from July 2007, and the law is not retroactive, since the “T-MEC would not be applicable to the facts related to this controversy.”
  • Grupo Mexico sees an impact beyond its San Martin Mine. The Mexican government will have the burden of proof to demonstrate in the T-MEC instance that there were no violations of union freedom in the San Martin Mine. If the case is lost, the sanctions could affect other company exports, beyond those originating from the facility in conflict, envisions the Grupo Mexico´s lawyer. It is worth remembering that the United States filed a labor complaint with the Mexican government accusing that, in the San Martin Mine, belonging to Grupo México, the rights of workers were violated because a strike was terminated by establishing a collective contract with another union, which would mean a violation of workers’ rights. Mexico maintained that this fact was prior to the entry into force of the trade agreement with the United States and Canada, and refused to carry out the investigation to determine a possible Remediation Plan for the company.

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of April 2023

By Jorge Cirett                                             

During the 17th week of the year (April 24th to April 30th, 2023), 17 companies working in Mexico released news on their work. Five companies informed on exploration on their properties, six companies informed on Q1 2023 or full-year 2023 production/financial results. Two companies announced the closing and opening of financing rounds. A company corrected assay information on a previously issued drill intercept; one other provided an update on its intention to sue the Mexican government under a NAFTA legacy claim regarding the lack of action to terminate an illegal blockade. ON MEXICO ISSUES, Canada’s ministry of International Commerce, Mary Ng, expressed the preoccupation of foreign investors on the incoming changes to the Mining Law. The Mining Law was passed on Saturday morning by the Senate, and is set to return discretionary powers to the State on mining concessions. ON EXPLORATION, in Sonora, Prismo Metals released assays from surface sampling at its Los Pavitos property; Regency Silver released good results from deep drilling at its Dios Padre project; Colibri Resource released results from drilling at Evelyn project. In Zacatecas, Radius Gold updated on exploration work at the Tropico property. ON MINING, Sierra Metals, Mag Silver, Santacruz Silver, Alamos Gold, Pan American Silver and Agnico Eagle released Q1 2023 production reports. ON FINANCING, Silver Viper closed a private placement for $3.3 M; Radius Gold is to raise $1.75 M. ON RESOURCES AND DEVELOPMENT, Oroco Resource corrected assay results from one hole, previously issued last week, from its Santo Tomás project in Sinaloa. ON DEALS AND CORPORATE ISSUES, Guanajuato Silver informed on managerial changes. Silver Bull is to sue the Mexican government if a deal is not reached on an incoming meeting regarding the lack of action by the government to terminate an illegal blockade on its Sierra Mojada project in Coahuila. Prismo Metals and Vizsla Silver formalized the joint technical committee to oversee exploration of the Panuco district in Sinaloa, with Peter Megaw, Craig Gibson and Jesus Velador as members. ON SOCIAL RESPONSIBILITY, no relevant news.

ON MEXICO ISSUES

  • The ministry of International Commerce of Canada, Mary Ng, expressed to Raquel Buenrostro, head of the Economy Secretariat (Secretaría de Economía) the preoccupation of foreign investors on the changes to the Mining Law, and the negative implications on North America supply chains.
  • The Senate Commission on Regional Development and Legislative Studies approved without changes, by the ruling party coalition senators of Morena, PT, PVEM and PES parties, the reforms to the Mining Law, National Waters Law, Ecologic Equilibrium Law, Environment Law, and the General Law for prevention and Comprehensive Treatment of Tailings in Matter of Mining and Water Concessions. Among the changes is the reduction of mining concessions validity from 100 to 80 years (under certain conditions), the instauration of an auction system by the government for mining concessions, establishing that the concession title is to be issued AFTER the environmental, labor, energy, social and any other federal permit needed have been received (Note by Editor. – Speaking of putting the cart before the horse).
  • On the changes to the Mining Law. (Note by editor) The reform to the Mining Law is directed to regain quasi absolute control of mining concessions by the government, establishing rules under which the concessions can be revoked on grounds of indigenous population, community issues, environmental issues and water scarcity, all on which the government plays the role of judge and party. This is part of a broader drive by the president to concentrate power in himself and his government coalition before the 2024 presidential elections.

ON EXPLORATION

ON MEXICO ISSUE

  • Servicios Industriales Peñoles S.A.B. de C.V., and Fresnillo plc recognized the role of women in mining, commemorating his legacy from the beginning of his participation in this sector. Both companies have maintained a strong gender agenda that offers equal opportunities to women and men, equal salaries that depend on the responsibilities of each employee, programs to prevent harassment and to reinforce female leadership.
  • In Mexico, women in mining have access to salaries up to 30% higher than the national average, with remunerations that exceed MXP $11K a month, above the MXP $5K and up to MXP $7K received by workers in the agricultural and construction sectors, textile employees, drivers and merchants, according to sector estimates. The mining industry has made progress on issues of diversity and inclusion, since in the last 13 years the participation of women has increased, going from 33,260 at the end of 2008 to 66,037 by 2022, according to data from Mining Chamber of Mexico (CAMIMEX).
  • According to figures from the Mexican Social Security Institute (IMSS), more than 66,000 women work in the mining-metallurgical industry, which is equivalent to 16.3% of the total workforce. The number of women who are entering careers in mining engineering, metallurgy and geology is increasing and therefore their presence in the productive field and in the management of the operation of mining units is increasing. Of the total number of women who participate in the industry, 10% hold directive positions and 14% hold management positions.
  • Proposals to modify the Mining Law lack support, say experts, since the industry complies with at least 4,000 legal obligations, before starting operations of a mining unit. The reform initiatives to the Mining Law that have been presented in the Congress of the Union lack support in the real circumstances of this industry or refer to issues that should be the subject of other legal regulations, as uncertainty for this activity. The experts explained that issues such as creating or increasing taxes and/or rights must be ruled out in the legislative drafts, since mining entrepreneurs pay, like any other taxpayer, the Income Tax, the Special Tax on Production and Services, in addition to they also pay mining rights and some local contributions, such as payroll and property taxes, as well as some of the so-called ecological taxes. They added that it is estimated that the tax burden of mining in Mexico is high, compared to other countries with mining activity. Mining is an industry misunderstood and unknown by many, even by those who promote changes to its legislation, for which they trusted that the voice of those who know and participate directly in the industry will be heard.
