ON MEXICO ISSUES
- Almadex Minerals Ltd., dropped several of its legacy projects in Mexico (Yago and Las Lajas projects in Nayarit and San Luis Potosi States respectively), “where exploration progress is challenged by numerous impediments to timely progress”.
- Galore Resources Inc., announced that due to some recent changes in the mining laws, enacted by the Mexican Government, Galore employed the services of a Law firm in Mexico to file an Amparo (injunction). “An Amparo is a constitutional remedy that protects individuals and entities against violations of their constitutional rights, in which this Amparo is the only legal remedy to challenge the constitutionality of the new mining laws. In the case of the Mining Concessionaires, it is important to exercise this right and obtain a resolution to make sure the authority will respect rights of previous concessions”.
- In 2022, the production of zinc, one of the six main metals that Mexico produces for its internal use and for export, was reduced because the federal authorities decided to reduce the operations of the mines. According to the Mexican Mining Chamber (CAMIMEX), the 2022 national mining production registered 744,324 tons, showing a decrease because in Zacatecas Newmont’s Peñasquito project reduced its tonnage to 34,473, while Fresnillo plc’s El Saucito project also limited its production to 9,054 tons less. In addition, the mines La Platosa owned by Excellon Resources, La Cienega owned by Fresnillo plc and Velardeña owned by Industrias Peñoles decreased their volumes by 40.6%, 15.5% and 4.6%, respectively. Chihuahua is another state whose production decreased with Grupo Mexico’s Santa Barbara project, which registered 20,696 tons, 11.5% lower than the previous year; and San Francisco del Oro from Minera Frisco with 17,923 tons, 4.3% less compared to 2021. Other states in which their mines decreased their production were: San Luis Potosí, with Charcas from Grupo Mexico, with an annual decrease of 16.4%; in Aguascalientes, Asientos of Minera Frisco, with 11.3%; in the State of Mexico, Tizapa with 5.9%, and in Guerrero with Capela, with 5.4%, both from Industrias Peñoles. Also, located in Guerrero, Luca Mining’s Campo Morado reduced its production by 23.2%. Zacatecas continued to be the most important, since its participation represented 48.4% of the national total and meant an increase of 1% compared to 2021. Durango was in second place in zinc mining production, but reduced its production by 2.2% in 2022 compared to 2021, due to lower production in Santiago Papasquiaro of 16.3%. While Chihuahua was positioned in third place, where production remained unchanged compared to 2021; the largest reduction in state tonnage was due to the municipality of San Francisco del Oro. “By company, Newmont was the largest national zinc producer in 2022, with a 23% share. The four most important companies of national origin that participate in the extraction of this metal are: Industrias Peñoles, Fresnillo plc, Grupo Mexico and Minera Frisco, which represented 50% of the total last year”, the document reiterates. CAMIMEX assured that there are projects that will boost the growth of zinc production in Mexico in the next five years and that, if they are taken advantage of, they could place Mexico among the top five producers worldwide. The foregoing would also mean a recovery of the industry after the impact of the pandemic and the impact on mineral prices. Among the main projects with this metal content in Mexico, Grupo Mexico’s Buenavista Zinc in Sonora stands out, as well as the San Nicolas development of Agnico Eagle-Teck in Zacatecas.
- Torex Gold Resources Inc., Sierra Madre Gold and Silver Ltd., Vizsla Silver Corp., and Prime Mining Corp., reported the best drilling intercepts in Mexico on the second week of July, 2023. Details are shown in the table below:
