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.

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

By Jorge Cirett

During the 41st week of the year (October 11th to October 17th, 2021), at least 25 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, six released Q3 reports and one on commencement of mining, two on financing and eight more on project development or resource definition and one more on mining concessions acquisitions. ON MEXICO ISSUES, Mexico’s president presented a proposal to change the law in the energy industry, but also restricting lithium exploration and production to the government. Several other elements could be included in the bill, referred to as “strategic minerals”, without elaborating, although a government party senator named cobalt, niquel, rare earths and even copper. ON EXPLORATION, In Sonora, Benjamin Hill Mining released results from geophysical processing and from fluid inclusion studies that support a buried intrusive source for the mineralization at the Benjamin Hill property; Canuc Resources updated on its deep drilling program at San Javier; Colibri Resources received the permit to drill Evelyn. In Chihuahua, Kootenay silver increased land holdings at its Columba project. In Sinaloa, Vizsla Silver presented drilling results from the Tajitos zone at its Panuco project.   ON MINING, Guanajuato Silver commenced mining at El Cubo, in Guanajuato. First Majestic Silver, Golden Minerals, Gold Resource, Magna Gold, Aura Minerals and Avino Silver & Gold Mines presented its Q3 2021 reports. ON FINANCING, Candelaria Mining informed one of its lenders, Accendo Banco, had its operating permit revoked by Mexican authorities. Xali Gold announced Sun River Gold arranged a financing for US$6.5 M for the tailings project at El Oro, Estado de Mexico. ON RESOURCES AND DEVELOPMENT, GR Silver Mining filed a NI-43-101 technical report on the Plomosas project, Sinaloa.

ON SOCIAL RESPONSIBILITY, Minera Media Luna, Peñols, Newmont Peñasquito and Pan American Silver informed on community programs in education and health.

ON MEXICO ISSUES

  • Mexico is far from being a powerhouse in lithium production according to the Statistical Review of World Energy 2021 by BP. Australia, Chile and China hold 81.2% of reserves and 86.5% of lithium production, whereas Argentina, Brazil, Portugal, the United States and Zimbabwe account for 20.5% of reserves and 12.8% of the production. Camimex (Cámara Minera de México) points that the constitutional reform presented by the Mexican president lacks technical support, as even if there are several lithium projects in Mexico, none has proven economic viability. The most visible of these projects, in Sonora, is said to be the largest lithium prospect in the Globe, but its economic viability has still to be proven, as to date there is not a single mine of lithium in clays in the World.
  • Mexico will not grant lithium concessions, said the Mexican president. He stated that even if his electricity reform is not approved by congress, his government has the power to reject any request for a concession to mine lithium. “We will deny any request for a concession to mine lithium and we have the power to do so. We want this to be established in the constitution, lithium belongs to the state”.
  • Nationalistic views with control on “strategic minerals” have been voiced by Morena, the party in power in Mexico. Besides the explicit aim by the President to save all lithium extracting and processing activities for the government, his recent proposal also refers, without elaborating, to be applied in other “strategic minerals”. A senator form Morena mentioned these other minerals could include cobalt, nickel, rare earths and copper, although a spokeswoman from the Economy Secretariat mentioned that the list of strategic minerals was to be provided by the Mexican Geological Survey at a later date.

ON EXPLORATION

  • Canuc Resources Corp. updated on the exploration program at its San Javier project in Sonora. Three holes have been completed and a fourth one is in progress, currently at 922 m of depth and ongoing. Chalcopyrite has been encountered from 302 m and is still visible at 922 m of depth. “The drill hole has intersected a broad zone of variably stockworked and brecciated Barranca sediments with minor andesitic dykes. The Barranca sediments show contact metamorphism from about 461 m and downward, variable amounts of magnetite bearing veinlets, stringers and breccia matrix throughout”. The first two holes intercepted Barranca Formation sedimentary rocks with magnetite veinlets and best intercepts of 2.35 m @ 126 gpt Ag and 2.0 m @ 243 gpt Ag. The third hole was drilled on the Tarahumara Formation volcanic rocks for 500.5 m before being terminated due to drilling problems, intercepting several volcanic lithologies, chalcocite from 38 m of depth and sulfides including chalcopyrite from 332 m. Scattered gold and copper values on short intervals were intercepted, of up to 1.19 gpt Au and 0.41% Cu. Results for the current hole are still pending.
  • Colibri Resource Corp. received the needed permit to drill up to 56 holes at the Evelyn project in Sonora. “The fully funded drill program of up to 10,000 metres is expected to be conducted in two phases”.
  • Kootenay Silver Inc. increased its land holdings at its Columba project in Chihuahua. The company applied for a 10,825 hectare concession, supporting the decision to do so on the high-grade silver intercepts on drilling of the property.
  • Vizsla Silver Corp. presented the results from 23 new drill holes from the Tajitos vein at its Panuco project in Sinaloa. Highlighted true width intercepts comprise 1.38 m @ 1.16 gpt Au, 79 gpt Ag; 1.34 m @ 7.94 gpt Au, 960 gpt Ag; 0.70 m @ 4.16 gpt Au, 2,082 gpt Ag; 2.15 m @ 1.09 gpt Au, 188 gpt Ag; 1.38 m @ 2.83 gpt Au, 527 gpt Ag; 8.7 m @ 0.51 gpt Au, 99 gpt Ag; 1.99 m @ 2.46 gpt Au, 615 gpt Ag; 0.86 m @ 3.37 gpt Au, 315 gpt Ag; 1.39 m @ 3.26 gpt Au, 73 gpt Ag; 1.3 m @ 2.47 gpt Au, 600 gpt Ag; 1.50 m @ 9.90 gpt Au, 2,607 gpt Ag; 0.7 m @ 5.73 gpt Au, 1,115 gpt Ag; 4.38 m @ 1.62 gpt Au, 216 gpt Ag. The footprint of the Tajitos zone has been recognized for 800 m along strike and 300 m of depth.
  • Benjamin Hill Mining Corp. informed the seven kilometer long trend of epithermal mineralization at its Benjamin Hill project in Sonora is related to a well-defined magnetic anomaly. A magnetic high more than 12 kilometers long and 4 km wide lies beneath the surface, crossing the property in a N-NE orientation, with the Au-Cu mineralization parallel to the crest of the magnetic high.  “Our hypothesis explains that the magnetic anomaly corresponds to a partially exhumed fertile pluton. We suggest the mineralization seen at surface was driven by the heat engine of a buried pluton providing hydrothermal fluids that formed mineralized tabular bodies enriched with Au, Ag, and Cu (i.e. veins and breccias), as well as fluids that caused hydrothermal alteration halos (phyllic, epidote-magnetite and argillic alteration)…”.
  • Mammoth Resources Corp. updated on drilling at its Tenoriba project in Chihuahua. The company informed heavy rainfall during August and September is subduing by now, and that they expect an increase in the drilling rate that produced only 420 m of core in 8 weeks. “Mammoth intends to initially drill 2 – 4 holes within each target zone then move to another target zone to drill a similar number of holes”. Results on the first holes are pending.
  • Benjamin Hill Mining Corp. informed on results of fluid inclusion studies at its Benjamin Hill property in Sonora. The salinity and homogenization temperatures point to an epithermal system with an overprinting magmatic influence, and exhumation depths  between 150 m and 750 m in the mineralized structures. “This observation combined with recent geophysical data, supports the hypothesis of the existence of a mineralized plutonic source with a high possibility for Au-Cu metallic enrichment and porphyry potential”.
