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.

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 ISSUES

  • No relevant news.

ON EXPLORATION

  • Benjamin Hill Mining Corp (BHM), confirmed the presence of gold and copper mineralization at depth from channel samples collected underground in the Guadalupe and Cascabel adits at its Sonora Gold project. Highlights of the underground  samples collected over 2m intervals in the Guadalupe adit include 9.6 g/t Au and 0.5% Cu; 8.4 g/t Au and 0.3% Cu; 0.4 g/t Au and 4.3% Cu; 0.3 g/t Au and 3.5% Cu; and 0.2 g/t Au and 2.1% Cu. Highlights of the underground  samples collected over 1.5m interval in the Cascabel adit include 7.7 g/t Au and 0.4% Cu; 2.2 g/t Au and 0.4% Cu; 2.2 g/t Au and 0.7% Cu; 1.5 g/t Au and 2.9% Cu ; 1.3 g/t Au and 2.5% Cu; and 0.8 g/t Au and 2.4% Cu. Highlights of composites of channel samples from the underground sampling were calculated and include 1.54 g/t Au, 0.41% Cu, and 27 g/t Ag over 14m; 1.82 g/t Au,  0.88% Cu, and 44 g/t Ag over 7.5m; and 0.83 g/t Au, 0.38% Cu, and 19 g/t Ag over 7.5m. “The results of the underground sampling program proves that surface gold and copper mineralization extends to depth and supports BHM´s model of a copper-gold epithermal system. BHM geologists have previously mapped copper-gold mineralized structures over 8km cumulative length often attaining widths of 10´s of meters. The results of the adits sampling work supports the rational that the mineralized structures are drill ready targets”.

ON DEALS AND CORPORATE ISSUES

  • Excellon Resources Inc., provided an update on litigation involving the Company’s subsidiary, San Pedro Resources SA de CV (San Pedro) in respect of the La Antigua mineral concession (Evolution property, Zacatecas). Excellon received an initial electronic notice last July that San Pedro’s appeal to the federal courts of Mexico in respect of the litigation was dismissed, despite the lack of evidence, facts or law to support this outcome. The Company has now received the formal written decision on the appeal which, based on initial legal review, appears to uphold the judgment granting the plaintiff an award of approximately USD $23M and is not subject to further legal appeal in Mexico.  Brendan Cahill, President and CEO of Excellon, stated that “The value ascribed in the judgment is impossible based on evidence, facts or law. Simply put, the maximum value realizable by the plaintiff from the agreement on La Antigua was USD $500K in the best-case scenario, yet the Miguel Auza Mine was shut down in 2008 almost immediately after operations commenced.”

ON SOCIAL RESPONSIBILITY

  • Alamos Gold Inc., has allocated MXP $400M in environmental investment at its la Yaqui Grande mining project in Sonora. The foregoing consists of environmental remediation works that will be carried out as areas of the mine are vacated, a different model from the traditional work that waits until the end of the useful life of a mine to carry out reclamation and closure activities. In La Yaqui Grande, it is contemplated to have constant reclamation of areas, placing the vegetal roof covering in layers and stages, which implied a special design and engineering to make it possible throughout the seven years of operation. The company will also acquire a treatment plant that will allow the water used in the operation to be recirculated, reducing its consumption. The design of “tepetateras or dumps” is different from the traditional ones and there is already a nursery for the reproduction of native plants of the region, which will supply the demand for the development of this environmental project.

The Mining and Exploration News in Mexico: Highlights on the Fourth Week of May, 2021

By Jorge Cirett

During the 21st week of the year (May 24th to May 30th, 2021), at least 33 press releases were announced by companies working in Mexico. To note, seven companies posted exploration advances on their properties, three presented mining related news, seven posted on financing (C$6M, $60 M, C$5 M, C$10 M, $2.6 M, $C$11.5 M) and one on share distribution, six more on project development or resource definition and two posted on corporate issues. ON MEXICO ISSUES, CanCham complained on the lack of clear policies and opacity on the rule of law that are affecting Canadian investments in Mexico.  The push from the Mexican government to create an institution to manage the lithium industry from the optics of sovereignty sees opposition from the mining industry, and reality. Camimex released a list of mining investments to be realized in the next few years, amounting to several billion dollars. ON EXPLORATION, in Sonora, Ridgestone Mining applied for drilling permits at Rebeico. Tocvan Ventures released results from drilling at Pilar. In Chihuahua, Kootenay Silver released high-grade results from drilling at Columba. In Durango, Mithril Resources, updated on drilling at Copalquin. In Sinaloa, Riverside Resources released surface sample results; Vizsla Silver informed on geophysical results supported by drilling, and more surveys to come; Brigadier Gold discovered bulk tonnage copper mineralization in trenching of soil anomalies. ON MINING, Impact Silver and Telson Mining presented Q1 2021 results. Magna Gold informed it has exceeded 3 M man-hours of work without lost-time incidents. ON FINANCING, Silver Bull Resources is to distribute 34.2 M shares of Arras Minerals among its shareholders. Six companies informed on financing rounds: Silver Viper Minerals (C$6 M), Vizsla Silver ($60 M), Reyna Silver (C$5 M), Sable Resources (C$10M, Defiance Silver (C$11.5 M) and Mammoth Resources ($2.58 M). ON RESOURCES AND DEVELOPMENT, Prime Mining released drilling results from Los Reyes. GR Silver Mining reported near surface drill results from Plomosas. GoGold Resources released drilling results from the Casados deposit at Los Ricos North. Discovery Silver released results from 12 drill holes targeting high-grade vein trends at Cordero. Sailfish Royalty filed a technical report with a new resource estimate for Gavilanes. Discovery Silver updated on exploration at Cordero, with 75,000 m of drilling completed on 178 holes, and four drills continuing the phase 2 program. Golden Tag announced the discovery of a shallow zone of epithermal mineralization at San Diego.   ON DEALS AND CORPORATE ISSUES, Mexus Gold informed Fresnillo PLC is reviewing its Santa Elena mine. Riverside Resources announced BHP is funding a third year of generative work in Sonora. ON SOCIAL RESPONSIBILITY, Peñoles and Fresnillo PLC informed on their policies and programs to aid in education on a wide range of communities. Minera San Xavier informed Cerro San Pedro in San Luis Potosi has been declared as “Cyanide Free Site” by the International Cyanide Management Institute.

ON MEXICO ISSUES

  • CanCham (Cámara de Comercio de Canadá en México) pointed out that the lack of clear policies and the opacity on rule of law is affecting Canadian investments, which show an 18% decrement in the last year, holding the investment of thousands of millions (Mexican number notation) of dollars in the energy, mining, pharmaceutical and agricultural sectors. These remarks were expressed by Enrique Zorrilla, Cancham’s president, in the meeting between the Commerce ministers of Mexico, Canada and the United States.
  • Mexico is preparing its strategy to develop the lithium market. The federal government intends to become a lithium producer by controlling several deposits, Bolivia’s advice and a commerce treatise to facilitate establishing an electric battery factory. The current government senate fraction is preparing a proposal to create the Instituto Nacional del Litio. (Lithium National Institute) and to declare lithium as Nation’s exclusive property (Note. – This federal initiative push misses the point that so far there is not a single lithium mine in Mexico, that its lithium in brines potential is limited at best, and that the economics of lithium extraction from clays -like in the Bacanora Lithium’s deposit in Sonora- is not yet clear).
  • Fernando Alanís, president of Camimex (Cámara Minera de México) informed that lithium deposits in Mexico have a very low grade, and lack the technology for its extraction, reason for which the country is far from becoming a world power in lithium production. Lithium presents in three kind of deposits: hard rock (pegmatites), brines (from salt lakes) and clays. Rock and brine lithium extraction accounts for 100% of the world production, whereas the extraction of lithium from clays is very energy intensive and expensive, not having a single producing mine in the entire planet.

ON MEXICO ISSUES

  • Minera Penmont (Fresnillo plc) thanked the President of Mexico for his comments on the insecurity registered in Sonora. Two years ago, Minera Penmont denounced before state authorities the commission of various crimes, including the invasion of their property, perpetrated by a criminal group that claims to be part of the ejido. This group has absolutely no legal arguments and intends to take over the private property of the company to carry out mining exploitation actions outside the law, without the concession required for it, nor the corresponding environmental permits, using dangerous and controlled materials, directly affecting the Mexican State, the environment, the company and maintaining its criminal acts in the region.
  • Maria Luisa Albores, Head of the Ministry of Environmental and Natural Resources (SEMARNAT), traveled to Santa Rosalia to meets with businessmen and workers from El Boleo mining company.  She was entrusted with a consultation to find out the opinion of the population about the expansion of the environmental impact statement (MIA). Minera Boleo requested to expand the area of extraction, processing and shipment of copper minerals.
  • Plenary of the Guerrero State Congress approved recently the creation of the Mining Commission.  The president of the Political Coordination Board (Jucopo) of the local Congress, Alfredo Sánchez Esquivel pointed out that there is a real problem in the case of mining companies and the environment, for which the creation of this Commission was necessary. For his part, the state secretary of Promotion and Economic Development, Álvaro Burgos Barrera, considered the incorporation of a legislative commission to monitor the mining sector as highly relevant. He reported that in the current state administration headed by Héctor Astudillo Flores, governance allowed mining companies to invest approximately USD $2B in Guerrero.
  • Maria Luisa Albores, Head of the Ministry of Environmental and Natural Resources (SEMARNAT) made a series of unfortunate statements against the Mexican mining industry. She assured that the country’s mining activity has caused strong environmental effects, monopolizing water and causing social inequality. Her statements are full of biased and wrong information and caused immediately the strong reaction of different actors of the mining sector. Specialists of the sector declared that the view of the federal government has on mining is wrong. CAMIMEX has indicated that of the total water consumption in Mexico, 77% is used by agriculture; 14% is for public use; 5% to generate energy and 4% for industrial use and of the latter only 0.9% corresponds to milling. CAMIMEX also stated that 74% of the water used by this industry is recycled and, of that amount, 55% is continuously reused. In addition, the mining sector has 70 sewage treatment plants in the communities where it operates. There are dams that capture rainwater, which is given to the municipality, piped and sent to homes, when it is necessary. A large percentage of companies carry out social and human rights proceedings. They generate social and environmental programs. In 2019, mining companies allocated MXP $7,450M to actions in favor of the environment and MXP $1,756M to community development, in addition to the MXP $3,496M that were paid to the Mining Fund. Many companies have the largest plant nurseries in the country and have large animal rescue zoos that are delivered to the State. Mining is one of the industries that produces and plants the most trees, 6.6M million trees produced in the nurseries of mining companies; 2.93 million trees planted reforesting an area of more than 3,000 hectares in 2019. The Mexican mining industry is over-regulated and has to comply with seven environmental permits in the stage of exploration and nineteen environmental permits throughout the life of a mine. For the reasons stated above, the mining sector rejects the indications that point to that its activity does not respect the norms of protection of the environment and that it does not generate social welfare for the neighboring communities. That is why the sector unlocks the doors to the authorities with an open invitation to visit the operations and verify for themselves these realities of the mining sector and reliably inform the population.

ON EXPLORATION

  • Tocvan Ventures Corp., received permit for additional seven trenches and forty four drill pads at its the El Pilar project in Sonora. The additional drill pads will be used during the current program and during a phase III program planned for the fall of 2021.
