The Mining and Exploration News in Mexico: Highlights on the Second Week of July, 2021

By Jorge Cirett

During the 27th week of the year (July 5th to July 11th, 2021), at least 22 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, four on quarterly production and one about the end of an illegal blockade 17 months long, one posted on financing, five more on project development or resource definition and one posted an update on a law suite. ON MEXICO ISSUES, the illegal blockade on Americas Gold and Silver Cosalá operations in Sinaloa was terminated. Mexico has fallen 13 places on the Fraser’s Index on Mining Attractiveness, affected by perceptions on security and rule of law. ON EXPLORATION, in Sonora, Benjamin Hill Mining released surface assay results high in Cu and Au; Tocvan Ventures released results from RC drilling at Pilar. In Sinaloa, Brigadier Gold released drilling and underground sampling results from Picachos. In Durango, Canasil started drilling at Nora. In Zacatecas, Zacatecas Silver signed surface access agreements to the San Gill zone at its Zacatecas Silver project. In Oaxaca, Madoro Metals updated on exploration at Yautepec. ON MINING, GoGold Resources, Gatos Silver, Endeavour Silver and Torex Gold presented second quarter 2021 production results. Americas Gold and Silver signed an agreement with several ministries to reopen Its Cosalá operations in Sinaloa.  ON FINANCING, Gold79 Mines commenced trading on the OTCQB Venture Market in USA.

ON MEXICO ISSUES

  • Mexico has fallen 13 places in the Fraser’s Index of Mining attractiveness from 2008 to 2020. Investment also saw a 42.8% reduction in the same period, including some effect by the pandemic. Security, labor regulations, political instability, lack of mining concessions and a nationalization streak in the current government were cited as deterrents to investment in the country. Those viewpoints are reflected in less investment, less employment and fewer opportunities to find new orebodies, factors that will lead to  reductions in production and taxes to be paid in the coming years.
  • The illegal blockade on Americas Gold and Silver Cosalá operations is off. After 17 months of illegal blockade, the negotiations aided by the federal government can hardly be called a success. Events like this one add to the deterioration on the global perception of Mexico as a good place for mining investment.
  • The AIMMGM (Asociación de Ingenieros de Minas, Metalurgista y Geólogos de México) stated through its president Sergio Almazán, that investment in the Mexican mining sector has been affect by the lack of certitude.

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of May, 2021

By Jorge Cirett

During the 21st week of the year (May 24th to May 30th, 2021), at least 33 press releases were announced by companies working in Mexico. To note, seven companies posted exploration advances on their properties, three presented mining related news, seven posted on financing (C$6M, $60 M, C$5 M, C$10 M, $2.6 M, $C$11.5 M) and one on share distribution, six more on project development or resource definition and two posted on corporate issues. ON MEXICO ISSUES, CanCham complained on the lack of clear policies and opacity on the rule of law that are affecting Canadian investments in Mexico.  The push from the Mexican government to create an institution to manage the lithium industry from the optics of sovereignty sees opposition from the mining industry, and reality. Camimex released a list of mining investments to be realized in the next few years, amounting to several billion dollars. ON EXPLORATION, in Sonora, Ridgestone Mining applied for drilling permits at Rebeico. Tocvan Ventures released results from drilling at Pilar. In Chihuahua, Kootenay Silver released high-grade results from drilling at Columba. In Durango, Mithril Resources, updated on drilling at Copalquin. In Sinaloa, Riverside Resources released surface sample results; Vizsla Silver informed on geophysical results supported by drilling, and more surveys to come; Brigadier Gold discovered bulk tonnage copper mineralization in trenching of soil anomalies. ON MINING, Impact Silver and Telson Mining presented Q1 2021 results. Magna Gold informed it has exceeded 3 M man-hours of work without lost-time incidents. ON FINANCING, Silver Bull Resources is to distribute 34.2 M shares of Arras Minerals among its shareholders. Six companies informed on financing rounds: Silver Viper Minerals (C$6 M), Vizsla Silver ($60 M), Reyna Silver (C$5 M), Sable Resources (C$10M, Defiance Silver (C$11.5 M) and Mammoth Resources ($2.58 M). ON RESOURCES AND DEVELOPMENT, Prime Mining released drilling results from Los Reyes. GR Silver Mining reported near surface drill results from Plomosas. GoGold Resources released drilling results from the Casados deposit at Los Ricos North. Discovery Silver released results from 12 drill holes targeting high-grade vein trends at Cordero. Sailfish Royalty filed a technical report with a new resource estimate for Gavilanes. Discovery Silver updated on exploration at Cordero, with 75,000 m of drilling completed on 178 holes, and four drills continuing the phase 2 program. Golden Tag announced the discovery of a shallow zone of epithermal mineralization at San Diego.   ON DEALS AND CORPORATE ISSUES, Mexus Gold informed Fresnillo PLC is reviewing its Santa Elena mine. Riverside Resources announced BHP is funding a third year of generative work in Sonora. ON SOCIAL RESPONSIBILITY, Peñoles and Fresnillo PLC informed on their policies and programs to aid in education on a wide range of communities. Minera San Xavier informed Cerro San Pedro in San Luis Potosi has been declared as “Cyanide Free Site” by the International Cyanide Management Institute.

ON MEXICO ISSUES

  • CanCham (Cámara de Comercio de Canadá en México) pointed out that the lack of clear policies and the opacity on rule of law is affecting Canadian investments, which show an 18% decrement in the last year, holding the investment of thousands of millions (Mexican number notation) of dollars in the energy, mining, pharmaceutical and agricultural sectors. These remarks were expressed by Enrique Zorrilla, Cancham’s president, in the meeting between the Commerce ministers of Mexico, Canada and the United States.
  • Mexico is preparing its strategy to develop the lithium market. The federal government intends to become a lithium producer by controlling several deposits, Bolivia’s advice and a commerce treatise to facilitate establishing an electric battery factory. The current government senate fraction is preparing a proposal to create the Instituto Nacional del Litio. (Lithium National Institute) and to declare lithium as Nation’s exclusive property (Note. – This federal initiative push misses the point that so far there is not a single lithium mine in Mexico, that its lithium in brines potential is limited at best, and that the economics of lithium extraction from clays -like in the Bacanora Lithium’s deposit in Sonora- is not yet clear).
  • Fernando Alanís, president of Camimex (Cámara Minera de México) informed that lithium deposits in Mexico have a very low grade, and lack the technology for its extraction, reason for which the country is far from becoming a world power in lithium production. Lithium presents in three kind of deposits: hard rock (pegmatites), brines (from salt lakes) and clays. Rock and brine lithium extraction accounts for 100% of the world production, whereas the extraction of lithium from clays is very energy intensive and expensive, not having a single producing mine in the entire planet.
  • Camimex released a table with the Mexican Mining Developments programmed for the next few years, same that reach US$7,820 Million in investment (Mexican number notation, equivalent to US$7.8 billion).
