The Mining and Exploration News in Mexico: Highlights on the Third Week of July 2023

By Jorge Cirett                                              During the 29th week of the year (July 17th to July 23rd, 2023), 21 companies working in Mexico posted news releases. Two companies informed on exploration work at its properties and five more reported second quarter 2023 results. One company informed on the closing of a private placement, while six companies reported on work at their advanced properties and six more informed on acquisitions, company’s plans and issues. ON MEXICO ISSUES, mining companies are reflecting the changes in the business environment by making strategic moves, including diversification of the countries they operate in. The coal mine in Coahuila that registered two fatalities during the week had suspension orders since 2022.  Mining organization and experts question LitioMx ability to operate, and its almost non-existent budget. ON EXPLORATION, in Sonora, Regency Silver informed on drilling at Dios Padre; Prismo Metals reported on the trenching program at Los Pavitos. In Sinaloa, Prismo Metals informed on drilling at Palos Verdes. ON MINING, Americas Gold and Silver, Bear Creek Mining, First Majestic Silver, Golden Minerals and Avino Silver released production results for Q2 2023. ON FINANCING, Guanajuato Silver announced a bought deal private placement with a sole underwriter. ON RESOURCES AND DEVELOPMENT, Aura Minerals provided an exploration update for Aranzazu, in Zacatecas. First Majestic Silver reported exploration results from San Dimas, in Durango, and from Santa Elena, in Sonora. Heliostar Metals released drilling results from Ana Paula, in Guerrero, including the strongest gold intercept for Mexico in the year. GoGold Resources released drilling results from the Main Area of the Los Ricos South project in Jalisco. Gatos Silver updated on resource definition drilling at its Cerro Los Gatos property in Chihuahua. Endeavour Silver provided a construction update for its Terronera project in Jalisco. ON DEALS AND CORPORATE ISSUES, Riverside Resources provided an outlook of its ongoing activities, including a strengthening of its diversification out from Mexico. Radius Gold informed on the extension of the exclusivity agreement with Fresnillo PLC on the Plata Verde project, in Chihuahua. Newmont included several references to the suspension of activities at Peñasquito, in Zacatecas, on its Q2 2023 report. Golden Tag Resources updated on the La Parrilla (Durango) acquisition from First Majestic. Excellon Resources announced the sudden termination of the acquisition process of La Negra project in Queretaro by the vendor. Sierra Metals informed the conclusion of the “Special Committee” formed last year to tackle the challenging circumstances the company is addressing. ON SOCIAL RESPONSIBILITY, no relevant news. ON MEXICO ISSUES

  • Editor comments. The hostile stance at the mining industry since the instauration of the present federal administration in Mexico, which culminated with the passing of a mining law that is to practically stop any new exploration plays and make current operations riskier, is rendering results, with companies consolidating plans in their search for greener pastures. Riverside Resources is one of the few companies explicitly making public their diversification plans out from Mexico, but they are certainly not alone. Great Panther Silver is a company that bailed out before the president made the legal move to reflect its personal stance in the industry. Other companies are understandably doing the same, although the widespread anti-mining position in many countries generates second thoughts on the issue.
  • The Secretaría de Trabajo y Previsión Social (STPS-Work Bureau) pointed that the las visit to the Minera Fuga, in Coahuila, was in August 2022. During the review dangerous conditions were detected. Two workers died last week on the mine after falling 10 meters when the hoist winch failed. STPS ruled access restrictions and limitation of operations, which are still in force, “any operation of the mine is out of the law”.
  • Mining organizations and experts raise doubts on LitioMx ability to operate. Only US$2 M have been budgeted for exploration and evaluation of lithium deposits in 2023 and 2024. Just Bacanora Lithium has invested more than US$450 M in the definition of resources in its lithium-clay deposit in Sonora, as an example of the unreasonable amounts directed to the search for lithium. This is a large deposit with a questionable economic viability, as lithium is associated to clays, and an economic process to extract the lithium still has to be proved. In the World, 85% of lithium is mined from brines in dry lakes, and the rest from hard-rock pegmatites.

ON EXPLORATION

  • Regency Silver Corp. announced the completion of the phase 1 of the 2023 drilling program at its Dios Padre project in Sonora. Nine holes were drilled as follow up to the one that intercepted 35.8 m @ 6.84 gpt Au, 0.88% Cu, 22 gpt Ag and 9.8 m @ 13.97 gpt Au, 1.1% Cu, 50 gpt Ag on the 2022 program. Eight of nine holes intersected the target breccia zone down-dip and along strike, with the breccia appearing to widen with depth. A megacrystic quartz-feldspar porphyry appears to be the primary control for copper mineralization, with the high-grade sulfide breccia on the footwall of the porphyry. “The shallower intersections are more pyrite dominant with deeper intersections containing more specularite. Chalcopyrite appears to be highest in abundance where the breccia is proximal to the lower contact of the quartz-feldspar porphyry”. Final results will be released after reception and evaluation.
  • Prismo Metals Inc. reported that the trenching program at Los Pavitos property in Sonora has been completed. Results for 303 of the 347 samples collected from trenches have been received. “The trenching was generally focused on areas with little outcrop along strike from areas with quartz veining and high-grade surface assays”. Highlighted results comprise 6.4 m @ 0.1 gpt Au; 19.0 m @ 2.2 gpt Au, 23 gpt Ag (including 4.0 m @ 10.3 gpt Au, 104 gpt Ag) at Auras, 18.5 m @ 0.2 gpt Au; 2.1 m @ 1.7 gpt Au; 8.0 m @ 0.5 gpt Au; 7.8 m @ 2.3 gpt Au, 13 gpt Ag; 2.5 m @ 0.9 gpt Au, 70 gpt Ag; 17.70 m @ 0.13 gpt Au at Santa Cruz and 1.40 m @ 0.74 gpt Au at Española.
  • Prismo Metals Inc. is in the process of completing a 2,500 m drill program on its Palos Verdes project, in Sinaloa. The program was designed to test areas without previous drill access. Eight holes have been completed for a total of 1,500 m and assays have been received for the first seven holes. Results are expected to be announced next week.

ON MINING

  • Americas Gold and Silver Corp. provided Q2-2023 production results. The Cosalá operations in Sinaloa produced 335 K Oz Ag, 3.9 M Lb Pb, 9.9 M Lb Zn, benefitting from higher grade Ag areas in the upper zone of the San Rafael mine.

IMG_4731

By Jorge Cirett

During the 10th week of the year (March 2nd to March 8th, 2020), at least 25 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, several companies are interested exploring for lithium in Zacatecas-San Luis Potosí. Grupo Mexico plans to invest 78% more in 2020. Several mining companies are to invest more than $200 M in exploration in Mexico. The year 2019 was not good for the mining industry in the country, with an overall decrease in production. Durango’s governor announced mining investments for $100 M. The Peñasquito mine is expected to produce 1.6 M Oz AuEq per year for the next five years. The Industria Nacional de Autopartes (INA) is promoting the installation of a lithium battery plant. The Future of the Mexican Mining Industry seminar was held during the PDAC convention in Toronto, Canada.  Peñoles is to switch to LP gas its diesel truck fleet at one of its mines in Sonora (Milpillas?). ON EXPLORATION, in Durango, Chesapeake Gold optioned the Duraznito project, near the San Dimas mine. In Veracruz, Azucar Minerals released more drill results from its El Cobre project.  ON MINING, US Antimony reported the successful startup of the Los Juarez production facilities in Queretaro and Guanajuato.

ON MEXICO ISSUES

  • Claudia Pavlovich, Sonora’s governor, praised the work women realize in the State, while on a trip visiting mining communities, like Turicachi, Nacozari de García and Cumpas, where she realized various activities.
  • Gustavo Puentes, Secretary of Economic Development, announced several companies are interested in investing in lithium exploration in the border between San Luis Potosi and Zacatecas.
  • Camimex (Cámara Minera de México) supports women collaborators that unite on the movement #UnDíaSinNosotras (One day without us) that is trying to eradicate genre violence.
  • The inauguration of Mexican Stand on the Prospectors and Developers of Canada Convention (PDAC) in Toronto counted with the participation of Graeme Clark, Canada’s ambassador in Mexico, Juan José Gómez Camacho, Mexico’s ambassador in Canada, Francisco Quiroga, subsecretary of Mining, José rosas Aispuro, Durngo’s governor and Salvador García, president of the Asociación de Ingenieros de Minas, Metalurgistas y Geólogos de México (AIMMGM). The Mexico stand was possible due to the support of the AIMMGM, Peñoles, Minera Media Luna, Newmont, Alamos Gold, Endeaavour Silver, Asociación de Mineros de Sonora, Construplan, Detector Exploraciones, SSR Mining Pitarrilla, Santacruz Silver Mining, Starcore, International Mines, MacClean, Diesel Cargo, Accendo Banco, ROD General Contractor and Ecodrill, as the Mexican government no longer supports international promotion.
  • Grupo Mexico plans to invest 78% more in 2020. On mining the budget is US$1,217 M to produce 1.12 M tonnes Cu, further US$367 M to invest in transport and US$412 M in the infrastructure division.
  • Mining industry companies are to invest more than US$200 M in exploration in Mexico during 2020. Torex Gold plans to invest US$13 M in the Media Luna project; Fresnillo will invest over US$135 M in exploration in Chile, Peru and Mexico; First Majestic Silver will invest US$28 M in San Dimas, Durango and Santa Elena, Sonora; Pan American Silver is to invest more than US$37 M at Dolores in Chihuahua and La Colorada in Zacatecas.
  • Mining did not have a good year in Mexico in 2019. Mining is ongoing in 25 States, produces 8.1% of the industrial GNP and had a 5.1% contraction as result of the policies of the actual Federal Government. Since December of 2018 no new mineral concession titles have been granted, and the environmental regulator, SEMARNAT has delivered just one Environmental Impact Report (Manifestación de Impacto Ambiental, or MIA). In Puebla, a local court maintains a suspension of work on El Gorrión mine (Ixtaca) based on a legal complaint by a communal group (ejido) on a mineral concession the company no longer has. The Cosalá mine in Sinaloa is paralyzed by a conflict between unions masterminded by Morena’s senator Napoleon Gómez Urrutia, reminiscent of the conflict suffered by Torex Gold a few months ago under the same terms. The projected investments for US$5,343 M were not achieved, with the projected real figure likely to be around 60%, and exploration at 36% of the expected. Coming interactions of the industry with the Environmental regulator the sub secretary of mining, Francisco Quiroga and Alfonso Romo are to try to better the condition of the industry.
  • The governor of Durango, José Rosas Aispuro announced at the PDAC convention in Toronto, the investment of US$100 M in the mining sector during 2020 in the State.
  • The Peñasquito mine in Zacatecas is the biggest gold mine in Mexico, the second largest for silver and one of the biggest producers of zinc and lead. The mine is expected to produce 1.6 M Oz AuEq per year during the next five years. The company is striving to reduce costs and optimize the operation.
  • The Industria Nacional de Autopartes (INA) promotes the installation of a battery plant based on lithium, to take advantage of the natural resources and the industrial prowess of the country. Bacanora Lithium plans to invest US$420 M on the installation of a processing plant in Bacadehuachi, Sonora, in order to produce 17 K tonnes a year. About 85% of the lithium producers are in Asia, and USA produces 20% of the batteries. The nearness to the USA and sea ports are other advantages for project owned by Bacanora Lithium.
  • During December 2019 mining grew by 0.9% thanks to the push given by a raise of 19.1% in lead production. For the year, mining decreased 1.5%, while lead production grew 13.3%. Los Gatos, in Chihuahua; Minera Capela in Guerrero; San Martin and Peñasquito in Zacatecas and production by Fresnillo aided in the growth seen by the bluish gray metal. Production rates from other metals show increments and decrements to the following tenor During December: Gypsum +14.4%, zinc +8.8%, silver +7.8%, sulphur +5.2%, coke -25.8%, iron pellets -7.3%, coal -5.2%, gold -2.2%, copper -0-8%. For the year: Overall -1.5%, gold -10.2%, silver +1.1%, copper +4.8%, zinc +7.0%, lead +13.3%, iron pellets -0.5%, coke -16.0%, Sulphur -14.7%, fluorite -5.0%, coal -2.0%, gypsum -0.6%. The trend reflects years of decreasing investment in mining, although some new developments might increase the production on lead, zinc, silver and copper.
  • The Future of the Mexican Mining Industry seminar was held during the PDAC convention in Toronto, Canada. Four environmentally focused conferences opened the seminar in which a dialogue table was set with the Mining Sub Secretary Francisco Quiroga, several governors, union leaders, mining company executives, financial analysts and congressmen.
  • Lithium exploration projects in Mexico: There are more than 20 lithium exploration projects in the country, most within Sonora, Zacatecas, San Luis Potosí, Baja California and Coahuila. The most advanced is Bacanora Lithium’s Sonora project in Bacadehuachi, but other interesting properties are comprised by OrganiMax’s Salar La Salada in Zacatecas, and Salar Santa Clara and Salar Caliguey in San Luis Potosí; Litio Infinito’s project in Sonora, adjacent to the ground held by Bacanora Lithium and One World Lithium’s Salar del Diablo project in Baja California.
  • Industrias Peñoles intends to change the fuel used by its mining trucks fleet in a mine in Sonora. The change involves modifying the trucks to run on LP gas instead of diesel (Milpillas mine?).

ON EXPLORATION

  • Chesapeake Gold Corp. announced it has an option to acquire El Duraznito project in Durango, which is 18 Km East of First Majestic’s San Dimas mine.
