ON MEXICO ISSUE

  • Jaime Gutiérrez Núñez, President of the Mexican Mining Chamber (CAMIMEX) stated that political risk causes a reduction in the mining investment in Mexico.  The lack of legal certainty and a complex environment for obtaining licenses and concessions are holding back investment in the Mexico’s mining sector, despite the rise in metal prices. Actual spending was USD $4.25B, 15.6% below the original estimates, according to CAMIMEX. The figure is lower than the USD $4.67B in 2019 and is well below the high of USD $8.42B in 2012.  Due to the lack of mining concessions, investment opportunities of USD $25B are lost in the country. Currently, there are 29 applications detained in the Secretary of the Environment and Natural Resources (SEMARNAT) and 34 at the National Water Commission (CONAGUA). With an adequate legal framework and adequate incentives, mining activity could generate 50 thousand additional direct jobs and more than MXP $25B a year in addition to those already paid by mining. “The statements of the President (against mining), not granting mining concessions, denying access to information, making procedures increasingly slow, although the terms are established in the law, and the lack of personnel in the Mining Directorate General  have impeded the advancement of mining projects in the country”.
  • Alfonso Durazo, governor of Sonora State, declared that the Mining Fund program could be back in the state after it was frozen for a little more than three years by the Federal government. If the Mining Fund is back, the injection of resources into the entity in this 2022 will be greater than MXP $1,000M, same that will benefit the mining towns and incidentally will give a good respite to state public finances.

ON MEXICO ISSUE

  • Great Panther Mining Limited announced that it has begun the closure process at its Guanajuato facility. Great Panther issued a statement announcing the gradual closure of activities, due to not having the respective permit to expand tailings storage in the Jolula Dam, which is part of the mining complex. According to Great Panther, the permit was requested to the National Water Commission (CONAGUA) but so far it has not been authorized. For that reason the company cannot continue operating; but the operations will return, once they receive said authorization. The activities will continue solely for the care and maintenance of facilities. The mines that will be shut down are San Ignacio, the Guanajuato Complex and the Jolulaprocessing plant, located in the former Hacienda de Bustos, also known as ‘Cata’. Mine workers have expressed concern about the situation because when the activities stop in the mines in which they work they will lose their economic income. The precise data on how many employees will be affected by the situation is not yet available.

ON EXPLORATION

  • Aztec Minerals Corp., and its JV partner Kootenay Silver Inc., commenced a 5,000m RC drilling program to test four main targets at the Cervantes project in Sonora. “The primary objectives of the drilling program are to better define the near surface, oxide gold potential of the porphyry gold oxide cap at California, evaluate the potential for deeper copper-gold porphyry sulfide mineralization underlying the oxide cap, test for north and west extensions of the California mineralization at California North and Jasper, and assess the breccia potential of Purisima East”.
  • Barksdale Resources Corp., announced the completion of the Phase I, 5,000m drilling program conducted at the Cerro Verde Zone within its San Javier project. All of the 36 holes collared at Cerro Verde encountering Cu mineralization.

ON MEXICO ISSUES

  • Fortuna Silver Mines Inc., announced that it is trying to avoid the closure of its San Jose silver mine in Oaxaca after the expiration of its environmental permit last month. Although the San Jose mine has been in operation since 2011, its main environmental authorization expired on October 23, despite the company’s efforts since May to request an extension of the permit. A recent court order allows the mine to continue operating, but only temporarily. Maria Luisa Albores, the Environment Secretariat issued a statement saying it would work to organize a consultation with indigenous communities close to the project as part of the environmental authorization. It did not provide details on the timing of the consultation, nor did it say whether the mine could continue to operate in the meantime. The company stated that it is fighting for the stability of 1,200 active workers of its San Jose mine.
  • Mexico’s Secretary of the Environment and Natural Resources (SEMARNAT) announced that it will carry out an indigenous consultation to define the future of the San Jose mine in Oaxaca. A dozen of Zapotecas communities will decide whether the San José mine, owned by Minera Cuzcatlán, will continue operating in the Valles Centrales region of Oaxaca, through a consultation carried out by the Ministry of SEMARNAT. It should be noted that the San José mine has four environmental impact authorizations in force, however there is another one that expired on October 23, and although the company requested its extension in due time and form, SEMARNAT has not issued a ruling.
  • Fortuna Silver Mines Inc., provided an update on the appeal to the denial of the extension of the environmental impact authorization (EIA) at its San Jose mine, Oaxaca. “The appeal will be brought by Minera Cuzcatlán in the Mexican court. The grounds for the appeal are that Minera Cuzcatlán is in full compliance with all material environmental laws, and therefore Minera Cuzcatlán has the right to an extension of the EIA under applicable law”.

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. Orla Mining provided an update on the construction of the Camino Rojo Oxide project. Prime Mining released further drilling results from Los Reyes, Sinaloa. Fabled Silver Gold released underground drilling results for Santa Maria, in Chihuahua. GoGold Resources reported results from drilling at El Favor, on its Los Ricos North project located in Jalisco. Golden Tag resources is adding 4,500 m to its 2021 drilling program at San Diego, Durango. Capitan Mining reported results from drilling at El Capitan, in Durango.

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”.

ON MEXICO ISSUE

  • Members of the Mining Cluster of Chihuahua met with federal deputies of the Partido Acción Nacional (PAN) to let them know of the importance of mining not only in the state but in the entire country. Deductions of the mining exploration expenses as well as the electricity reform were some of the issues addressed to the deputies. According to the mining sector, if the electricity reform is approved, it will affect the competitiveness of mining. The Mining Cluster, in communion with government authorities, seeks to generate the development of local supply, as well as attracting greater mining investment in the state.
  • President AMLO announced a proposal that would put end the current system of lithium concessions and leave exploration and production in the hands of the State. However, the owner of the USD $420M project Bacanora Lithium stated that the Mexican government’s plans to bring lithium resources under state control will not affect progress in Sonora, since the new reforms will not affect lithium licenses already granted to private companies, as long as exploration work has already started and all licensing requirements have been met.
