Quartz Vein-Breccia

By Miguel A Heredia

During the 24th week of the year (June 14th to June 20th, 2021), at least 15 press releases were announced by companies working in Mexico and 6 news published by the media, with seven reporting on resources and developments, five informing on exploration results, four commenting on Mexican issues, two announcing financial rounds, two discussing social issues, and one disclosing deals and corporate issues.  ON MEXICO ISSUES, Dhipna Yanssen Weichselbaum, head of the Federal Programs in Baja California explained that 12,000 people will be consulted in Mulegé to carry out the consultation of El Boleo. The Argentine Embassy in Mexico along with the Ministry of Mining of that country carried out a working seminar with the Mexican company Baluarte Minero (Industrias Peñoles and Fresnillo PLC). The consultation for the nationalization of lithium, proposed by President Andrés Manuel López Obrador, is not necessary, since, it is already owned by Mexico. ON EXPLORATION, In Sonora, Tocvan and its JV partner Colibri reported drill results from its the El Pilar project, and Tarachi started a second drilling program on its San Javier mining concession at La Colorada gold bearing breccia pipe. In Chihuahua, Mammoth reported results from an additional 1.7km of 3D geophysical modeling conducted at its Tenoriba project. In Nayarit, Sierra Madre provided an update on the activities developed at its Tepic project. ON MINING, no relevant news. ON FINANCING, Azucar granted stock options to certain directors and officers of the company (El Cobre project, Veracruz). Advance Gold closed a private placement financing for gross proceeds of $200K (Tabasqueña project, Zacatecas). ON RESOURCES AND DEVELOPMENT, Almaden completed a surface induced polarization geophysical (IP) program at its Ixtaca project in Puebla. GoGold released results from eight drill holes collared at its Los Ricos project in Jalisco. Silver Viper filed on SEDAR a NI 43-101 technical report supporting the maiden mineral resource estimate for its La Virginia project in Sonora. Torex released an updated mineral resource estimate for its media Luna project in Guerrero. Zacatecas Silver announced positive preliminary metallurgical test results from its Zacatecas Silver property. Excellon filed on SEDAR an independent NI 43-101 technical report for its La Platosa mine in Durango.

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).

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

Rich-silver banded quartz vein

By Miguel A Heredia

ON MEXICO ISSUES

  • Minera Penmont (Fresnillo plc) thanked the President of Mexico for his comments on the insecurity registered in Sonora. Two years ago, Minera Penmont denounced before state authorities the commission of various crimes, including the invasion of their property, perpetrated by a criminal group that claims to be part of the ejido. This group has absolutely no legal arguments and intends to take over the private property of the company to carry out mining exploitation actions outside the law, without the concession required for it, nor the corresponding environmental permits, using dangerous and controlled materials, directly affecting the Mexican State, the environment, the company and maintaining its criminal acts in the region.
  • Maria Luisa Albores, Head of the Ministry of Environmental and Natural Resources (SEMARNAT), traveled to Santa Rosalia to meets with businessmen and workers from El Boleo mining company.  She was entrusted with a consultation to find out the opinion of the population about the expansion of the environmental impact statement (MIA). Minera Boleo requested to expand the area of extraction, processing and shipment of copper minerals.
  • Plenary of the Guerrero State Congress approved recently the creation of the Mining Commission.  The president of the Political Coordination Board (Jucopo) of the local Congress, Alfredo Sánchez Esquivel pointed out that there is a real problem in the case of mining companies and the environment, for which the creation of this Commission was necessary. For his part, the state secretary of Promotion and Economic Development, Álvaro Burgos Barrera, considered the incorporation of a legislative commission to monitor the mining sector as highly relevant. He reported that in the current state administration headed by Héctor Astudillo Flores, governance allowed mining companies to invest approximately USD $2B in Guerrero.
  • Maria Luisa Albores, Head of the Ministry of Environmental and Natural Resources (SEMARNAT) made a series of unfortunate statements against the Mexican mining industry. She assured that the country’s mining activity has caused strong environmental effects, monopolizing water and causing social inequality. Her statements are full of biased and wrong information and caused immediately the strong reaction of different actors of the mining sector. Specialists of the sector declared that the view of the federal government has on mining is wrong. CAMIMEX has indicated that of the total water consumption in Mexico, 77% is used by agriculture; 14% is for public use; 5% to generate energy and 4% for industrial use and of the latter only 0.9% corresponds to milling. CAMIMEX also stated that 74% of the water used by this industry is recycled and, of that amount, 55% is continuously reused. In addition, the mining sector has 70 sewage treatment plants in the communities where it operates. There are dams that capture rainwater, which is given to the municipality, piped and sent to homes, when it is necessary. A large percentage of companies carry out social and human rights proceedings. They generate social and environmental programs. In 2019, mining companies allocated MXP $7,450M to actions in favor of the environment and MXP $1,756M to community development, in addition to the MXP $3,496M that were paid to the Mining Fund. Many companies have the largest plant nurseries in the country and have large animal rescue zoos that are delivered to the State. Mining is one of the industries that produces and plants the most trees, 6.6M million trees produced in the nurseries of mining companies; 2.93 million trees planted reforesting an area of more than 3,000 hectares in 2019. The Mexican mining industry is over-regulated and has to comply with seven environmental permits in the stage of exploration and nineteen environmental permits throughout the life of a mine. For the reasons stated above, the mining sector rejects the indications that point to that its activity does not respect the norms of protection of the environment and that it does not generate social welfare for the neighboring communities. That is why the sector unlocks the doors to the authorities with an open invitation to visit the operations and verify for themselves these realities of the mining sector and reliably inform the population.
