ON MEXICO ISSUE

  • Colibri Resource Corporation and Oroco Resource Corp., reported the best drilling intercepts in Mexico on the fourth week of August, 2022. Details are shown in the table below:
·        The government of Mexico announced, through a decree in the Official Gazette of the Federation, the creation of the state company Litio para Mexico (LitioMx). The Government of Mexico created LitioMx as a decentralized public organism of the Federal Public Administration and coordinated by the Ministry of Energy, with its own legal personality and assets and with technical, operational and management autonomy. The objective of LitioMx will be the exploration, exploitation, benefit and use of lithium, located in national territory, as well as the administration and control of the economic value chains of such mineral.
·        According to the Mining Chamber of Mexico (CAMIMEX), a total of 822 mining projects remain on hold and represent an amount of USD $959M, which are still waiting for better conditions to be able to reactivate. Jaime Núñez, president of CAMIMEX stated that is essential to encourage exploration since unfortunately in the last seven years we have seen a decrease in investments in exploration, leaving several projects on standby.
·        Jaime Gutierrez Núñez, president of CAMIMEX stated that small-scale coal mining is like “the blood diamonds” of Africa, and that the Federal Electricity Commission (CFE) should certify where the mineral it buys comes from and its conditions.
·        Mexico’s mining industry plans to invest USD $5.5B in 2022, 15.2% more than in 2021, but according to the Mexican Mining Chamber (CAMIMEX), it will remain below the record figure of USD $8.04B seen in 2012 amid difficult conditions. Growing security problems, a high tax burden and the government’s decision to stop granting concessions for projects have prevented investments in the sector from increasing faster, said CAMIMEX head Jaime Gutiérrez.
·        Mining in Mexico grew by 7.1% in 2021 despite friction with the government. According to CAMIMEX’s annual report, this increase positioned it as the only productive activity that recovered and even exceeded the fall of 2020, when the covid-19 pandemic initially stopped its operations because the government did not consider it “essential activity”. Even without tax incentives, the mining sector presented an increase in its contribution to the gross domestic product (GDP) going from 2.3% in 2020 to 2.5% in 2021, and an annual advance in the proportion of industrial GDP from 8.3% to 8.6% in the same period.
·        The Governor of Durango, José Rosas Aispuro, considered unfair that the mining-metallurgical sector is one of the economic sectors with the highest tax burden in the country, even though it is an enabler that prevents the migration of people in the communities where it develops its production processes, for job creation and social benefits. Mining Entrepreneurs stated that mining generates jobs and is one of the industries that pays the most taxes, since in 7 years it has contributed more than MXP $240,000M (approximately USD $12B) in taxes and other rights.
·        In Mexico there are more than 1,209 mining projects that have been developed in 26 states of the Republic, in which 406,179 jobs have been generated and a production value that already exceeds MXP $334,782M (approximately USD $16.7B). Among the main minerals extracted from these deposits are gold, copper, silver, zinc, iron, molybdenum, lead, fluorite, among others. For its exploration and exploitation, in 2021 alone, investments have been made for more than USD $4,810M and more than USD $5,538M are expected by the end of 2022. Of the 1,209 mining projects that exist in Mexico, 286 are in Sonora, Chihuahua has 160 and Durango has 128, which positions them as the entities with the greatest economic benefit thanks to mining concessions. Of the total number of projects, 749 correspond to precious metals; 180 to polymetallic minerals, 167 to copper, 71 to iron ore and the remaining 42 to other metals and minerals. According to the Mexican Mining Chamber (CAMIMEX), there are currently a total of 263 projects in the exploration stage, 76 in production, 39 in the development stage, while 822 projects are being postponed and 9 operations are reported as closed. However, the agency assures that, since the start of the current administration, the federal government has stopped granting permits or concessions for the exploration and development of new projects, since so far more than USD $959.7M dollars have not been invested. .

ON EXPLORATION

  • Silver Spruce Resources Inc., filed environmental permits with the Secretariat of Natural Resources and Environment (SEMARNAT) to drill at their the Diamante, Mezquite and Jackie projects in Sonora. Approvals from SEMARNAT are expected to be obtained by late March, 2022.
  • Canasil Resources Inc., provided a review of the results from its 2020-21 drill program on the Candy Vein at its Nora project. 13 drill holes were completed for a total of 3,296m to test the Candy vein over a strike distance of 500m and to a vertical depth of 250m below surface. All the holes encountered the mineralized vein with the highest true width x grade value on hole NRE-21-11 with 5.31 g/t Au and 336 g/t Ag (748 g/t AgEq) over a true width (TW) of 11.29m, giving a TW x grade value of 8,445 g/t AgEq x m. The drill results show that the Candy vein hosts consistently high grade gold and silver mineralization over appreciable widths. The Candy vein is known over 3km long but only 500m have been drill tested. Additionally, Canasil reported that systematic grid soil sampling over a 2km east-west and 3km north-south area covering the central zone of the project returned widespread silver, gold, copper, zinc and lead geochemical anomalies. “The gold and silver anomalies are particularly strong over the 3-Km strike extent of the Candy vein structure on the western side of the project area, as well as to the southwest and east of the Candy vein structure. A strong silver and gold anomaly also extends for 1.5 Km southwest from the location of the above high grade drill intercepts on the Candy vein and a breccia target has been identified to the south with potential for hosting bulk tonnage disseminated silver-gold mineralization”.
  • Silver Wolf Exploration Ltd., provided a 2021 year in review and 2022 outlook on its Ana Maria property in Durango. The accomplished goals on 2021 include the completion of a NI-43-101 compliant technical report on the properties; an Aster satellite imaging survey, an airborne LiDAR and Hyperspectral imaging survey, an Airborne geophysical data survey, the application to expand the land package by 3x, and the completion of the 2021 mapping and sampling program to identify prospective areas and uncover previous historical workings.

ON MEXICO ISSUE

  • AMLO reaffirmed this week his foolish and unfortunate policy of not granting more mining concessions in Mexico. He declared that mining companies were speculating in the financial market. López Obrador asserted that the existing mining concessions will be respected; however, his government will no longer give more, as many companies “cheated” and have not carried out exploitation tasks.
  • President Andrés Manuel López Obrador offered to meet the request of residents of San José del Progreso and collaborators of Compañía Minera Cuzcatlán, who asked him to avoid the closure of the San José mining unit, located in that Oaxacan municipality. The president was asked to avoid the loss of more than 1,200 direct jobs and around 8,000 indirect ones.
  • The current government has stopped the issuance of mining concessions and investment in Mexico. Parallel to the policy of null concessions, the president has presented a bill that intends to reserve strategic minerals such as lithium only for the State, denying any concession for their exploration, production or commercialization. Both their decisions not to grant a single concession in three years of government “and the promise not to do so in the entire six-year term”and to reserve strategic minerals for the State have been strongly criticized by specialists and representatives of the mining industry, to the point of warning that the future of the country is being“mortgaged.

By Jorge Cirett

During the 43rd week of the year (October 25th to October 31st, 2021), at least 34 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, six released Q3 reports, one on commencement of mining and one other in red tape issues, there were no financing related news, while ten companies posted on project development or resource definition and one more on a project acquisition. ON MEXICO ISSUES, a leftist senator asked for the Mining Fund to be reinstated for the benefit of communities. The head of the Energy Secretariat confirmed plans to create a lithium State company, and the government’s drive to monopolize the electricity market. Mixed market results for Mexican companies in 2021. ON EXPLORATION, In Sonora, Colibri Resources updated on drilling preparations. In Chihuahua, Reyna Silver has drilled the first skarn intervals in the Guigui project, rising the stakes and probing that pursuing geological models can pay off. Radius Gold released good drill results from the California target in the Amalia project. In Durango, Silverton updated on exploration activities at Pluton. In Sinaloa, Brigadier Gold released trench results from El Placer vein system at its Picachos property. In Nayarit, Sierra Madre Gold and Silver released surface sample results.   ON MINING, Fortuna Silver is awaiting a resolution on an application to continue mining at San José, in Oaxaca. Agnico Eagle, Altaley Mining, Guanajuato Silver, Alamos Gold, Coeur Mining, Gold Resource and Fresnillo PLC presented their Q3 2021 reports. Guanajuato Silver shipped its first concentrate from El Cubo mill. ON FINANCING, for the first time in a long period, no relevant news on this matter.

  • Rocío Nahle, head of the Energy Secretariat, confirmed plans to create a lithium State company, as part of a wider reform in the electricity industry, same that is seen as containing expropriation streaks. The private sector is overwhelmingly against this reform, that is seen to conduct to higher energy prices and pollution, as well to scare other investments from the country.
  • Mixed results for Mexican Mining companies reflect changes in metal prices. Companies that have seen their stock tumble during 2021 include Fresnillo (-20.7% in Mexico, -18.3% in London). Peñoles (-11.4%) and Frisco (-4.2%) by their exposure to precious metals that have contracted by 5% in the case of gold and 7.4% for silver. Companies that have seen their stock appreciate include Autlán (+23.5%) and Grupo Mexico (+13.5%), the latter due to the 26.7% increase in the copper price.

ON EXPLORATION

  • Silverton Metals Corp. updated on the exploration activities at the Pluton project 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).
