ON MEXICO ISSUES

  • Governors of Guerrero, Chihuahua, and Durango showed their support for the mining industry during the inauguration of the XXXIV International Mining Convention in Acapulco because it represents a lever for the economic development of the country. They promised to respect the rule of law to promote the investment in the sector that generates jobs and benefits to the communities where it operates.
  • Jaime Gutiérrez Núñez, president of The Mining Chamber of Mexico Camimex stated that the suspension of new mining concessions as well as the effects of the possible approval of the electricity reform and the heavy tax burden is generating strong uncertainty in the mining sector in Mexico.
  • Tonatiuh Herrera Gutiérrez, Undersecretary of Promotion and Environmental Regulations of the Secretariat of the Environment and Natural Resources (SEMARNAT), warned that the agency will keep consultations on land use for mining activity. Jaime Gutierrez Núñez, president of CAMIMEX responded that the companies affiliated to said organization do not oppose to the consultations on land use for mining activity, but emphasized that times should be established for conducting such consultations. Likewise, the Director of CAMIMEX, Karen Flores Arredondo stressed that “the rules of the game” must be clear and based on the General Consultation Law.
  • Miguel Ángel Riquelme Solís, governor of Coahuila State and Grupo Mexico signed an agreement to regularize properties in the Carboniferous Region of Coahuila. This regulation agreement represents legal certainty for more than 400 families in the Carboniferous Region.
  • The Mining Commission of the State Congress was installed, chaired by the deputy for Morena, Próspero Valenzuela Muñer to meet the demands and open a space for dialogue with the mining sector in Sonora. In that sense, he mentioned that it is important that said commission lays the foundations for the detonation of economic development and well-being in Sonora, taking advantage of the fact that this entity constitutes one of the main mining states in the country.
  • Octavio Alvídrez, CEO of the Mexican precious metals Fresnillo plc stated that mining in Mexico currently has an “unfavorable” environment due to recent government policies. President Andrés Manuel López Obrador has been criticized by the mining industry for his policy of not granting new concessions, as well as for what he has described as unprecedented regulatory delays. The president further fueled industry concerns by recently proposing to Congress a controversial energy constitutional reform that rejects concessions for Lithium.
  • The Mexican Geological Service (SGM) will invest MXP $55.2M between this year and the next in the exploration of lithium  with a view to finding an economically viable deposit, informed its director, Flor de María Harp. Exploration work will be carried out in 52 areas during 2021 and in another 30 in 2022. She explained that the country needs hard data so that we are not talking about what we believe, imagine or assume, but about data that have a technical basis. The official insisted that in Mexico expectations have been generated around lithium that is not real, because there is still no hard data on the potential of the mineral.
  • Karen Flores, director of the Mining Chamber of Mexico (CAMIMEX) stressed that due to lack of mineral concessions the mining industry in Mexico loses USD $25B with the consequent absence of jobs generation and the fiscal contribution. So far in this six-year term, no new concessions have been granted, in addition to the fact that there are procedures stopped that have also impacted on the continuity of some mining projects.
  • Sergio Almazán, president of the Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM), highlighted the relevance of the mining industry for the country’s economy in the inauguration of the XXXIV International Mining Convention in Acapulco. CAMIMEX, in its 2020 report stated that the industry currently generates around 408,000 direct jobs, plus almost 2 million indirect jobs. It means that many Mexican families literally live from mining. Mining activity stands out as the fifth earner of foreign currency to the country. He also highlighted that Mexican mining is a formal, modern, sustainable, safe, fiscally responsible industry, with competitive salaries and high quality standards.

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 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.
