ON MEXICO ISSUES
- Mexico fell 37 positions on the Fraser Institute index of mining competitiveness from 2022 to 2023, reflecting the difficulty to do business imposed in the new Mining Law.
- Camimex (Cámara Minera de México) indicated that mining exploration by the government as stated by the new mining law is just not viable. According to the new mining law, the only player able to do exploration before an auction of mining concessions is the SGM (Servicio Geológico Mexicano), and that in 2022 the SGM had a budget of just US$2.4 million dollars, compared with the annual average in the last 12 years of US$633 million dollars invested by private mining companies.
- Workers of Arcelor Mittal rejected a proposal by the company to end the more than a month and a half old illegal strike. The proposed agreement included more than US2,000 dollars per worker and 75% of the salaries not received during the strike, as well as an audit on the profits of the company for 2022 and 2023, to assess the correct application of the profit-sharing scheme in the law.

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

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of September, 2022.
By Miguel A Heredia
During the 38th week of the year (September 19th to September 25th, 2022), at least 12 press releases were announced by companies working in Mexico, and 3 news published by the media with four informing on exploration results, four reporting resources and developments of their properties, four commenting on Mexican issues, two announcing financing issues, and one discussing social issues. ON MEXICO ISSUES, Enrique Zorrilla, president of the Canadian Chamber of Commerce in Mexico stated that Canada has its eyes fixed on Mexico as an investment destination for its mining companies, mainly in exploration expenses to find new gold deposits. According to a recent report by the Ministry of Finance, Mexico values its lithium deposits in Sonora at USD $602,000M. In Mexico, only 33% of mines have access to a computer with an Internet connection to reduce accidents. On a striking difference with last week news releases, only Vizsla Silver Corp., posted drilling results in Mexico on the fourth week of September, 2022. ON EXPLORATION, In Sonora, Tocvan and its JV partner Colibri announced the next steps to be conducted at both the Pilar and the El Picacho projects. In Sinaloa, Prismo provided an update of its ongoing drilling program being conducted at its Palos Verdes project. In Durango, Regency entered into an option agreement to acquire a 100% undivided interest in the El Tablon claims. ON MINING, no relevant news. ON FINANCING, Tocvan announced that it has filed to extend the expiration date of 1,244,668 common share purchase warrants by six months (The Pilar project, Sonora). Barksdale closed a non-brokered private placement for gross proceeds of $2M and issued a total of 4,622,917 units at a price of $0.48 per Unit for gross proceeds of $2.22 (San Javier project, Sonora). ON RESOURCES AND DEVELOPMENT, Oroco announced the commencement of a Preliminary Economic Assessment (PEA) for its Santo Tomas project in Sinaloa. Galore provided an update on the exploitation activities carried out at its Duraznillo mine in Zacatecas. Golden Tag reported positive metallurgical results from the Fernandez Zone at its San Diego project, Durango.

ON SOCIAL RESPONSIBILITY, Almaden signed new and expanded cooperation agreements with the two communities closest to its Ixtaca project, Puebla.
ON MEXICO ISSUE
- Enrique Zorrilla, president of the Canadian Chamber of Commerce in Mexico stated that Canada has its eyes fixed on Mexico as an investment destination for its mining companies, mainly in exploration expenses to find new gold deposits. He declared that 35% of the capital invested by that country goes to the mining sector.
- According to a recent report by the Ministry of Finance, Mexico values its lithium deposits in Sonora at USD $602,000M. Although Mexico does not currently produce the metal, the finance ministry estimated that Sonora’s reserves could add about 0.3% to potential GDP in the medium term. While the ultra light white metal is usually extracted from rock or brine deposits, lithium in Sonora is mostly trapped in clays, from which it has not yet been extracted on a commercial scale.
- In Mexico, only 33% of mines have access to a computer with an Internet connection to reduce accidents. Ericsson revealed that the use of tools such as telemetry, satellite geolocation, wireless sensors and remote operation help improve mining operations, because with them and with the speed of the 5G network, information can be obtained practically in real time.
