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.

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”.

The Mining and Exploration News in Mexico: Highlights on the Fifth Week of September, 2021

By Jorge Cirett

During the 39th week of the year (September 27th to October 3rd, 2021), at least 20 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, one on financing and five more on project development or resource definition and one more on corporate matters. ON MEXICO ISSUES, Mexico’s government is looking for a law firm to represent its interests in international arbitration processes. A constitution amendment was proposed by the presidency of Mexico, to restrict the work of the private industry in the energy industry and to exclude private companies from the mining of lithium.   ON EXPLORATION, In Baja, One World Lithium is drilling at Salar del Diablo. In Sonora, Benjamin Hill Mining released assays from surface samples at the Benjamin Hill property. In Durango, Silverton Metals commenced exploration at the Pluton project; Silver Wolf Exploration released surface sample results for the Ana Maria project. In Zacatecas, Defiance silver is to start drilling the Lucita area on the Zacatecas project. In Oaxaca, Madoro Metals released radiometric ages on its Yautepec project.   ON MINING, No relevant news. ON FINANCING, Inomin closed a non-brokered private placement for $402.3 K in gross proceeds. ON RESOURCES AND DEVELOPMENT, GoGold Resources resources released drill results from the Mololoa area at its Los Ricos North project in Jalisco. Fabled Silver informed on drilling at its Santa Maria project in Chihuahua. Discovery Silver presented results from drilling at Cordero, in Chihuahua. Silver Dollar presented an update on La Joya, Durango. Silver Viper Minerals provided an update and drilling results from La Virginia, in Sonora. ON DEALS AND CORPORATE ISSUES, Altaley Mining engaged a group of consulting firms for financial publishing services and digital marketing services. ON SOCIAL RESPONSIBILITY, Capstone Gold informed on funding provided for sports in Zacatecas.

ON MEXICO ISSUES

  • Mexico’s government is looking for a law firm to represent its interests on international arbitration lawsuits, like the one brought by First Majestic Silver in the mining sector and Finley Resources, MWS Management and Prize Permanent Holdings on the oil services sector. Other relevant players that can initiate arbitration processes include Coeur Mining, AMERRA Capital Management, CMSA B. V., Contecon Manzanillo, Dal-Tile International, Doups Holdings, Gonzalo Mora Velarde and Jinlong Dongli Minera Internacional.
  • The Guerrero Gold Belt still has potential for 10 more million ounces of gold, according to David Jones, a geologist with extensive experience in the area. Torex Gold is to produce between 430 K to 470 K Oz Au in 2021 at its El Limon-Guajes mine, while Equinox expects to reach between 120 K to 140 K Oz Au, and both companies are in expansion development. Ana Paula is another known resource that can produce over 100 K Oz Au per year, in a belt with resources for more than 30 million ounces of gold. The state of Guerrero presents community and security issues that have to be addressed since the exploration stage, but that can be overcome, as the Los Filos and Guajes Limon mines demonstrate.
  • Mexico’s ejecutive power, president Andres Manuel Lopez Obrador presented an initiative that restricts the operations of private players in the electricity sector, and that also declares the government as the sole player in the mining of lithium (both measures reflecting a profound misunderstanding of economic processes, that is to erode into the country’s development rate and its inhabitants quality of life in the not so distant future, if approved).   

ON EXPLORATION

Little to no sulfur and organic carbon were observed on the testing. “There were no obvious variations in gold recovery related to ore zone or material type (vein breccia vs. stock work)”.
