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 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.

ON EXPLORATION

  • One World Lithium Inc., provided an update of its current drilling program at its Salar del Diablo project in Baja. The company announced that hole DDH-4 reached a depth of 381m on October 2, 2021 with an expected total depth of 600m. If the results of DDH-4 warrant it, other boreholes will be drilled in the area.
  • Benjamin Hill Mining Corp., provided an update of details on the recently released NI 43-101 report on its Benjamin Hill project in Sonora. “Detailed mapping at 1:1,000 scale has indicated the presence of a large magmatic-hydrothermal system, including mineralized structures, stockworks, sheeted veins, alteration halos, all of which are hosted in granitoids, an eroded skarn system, a volcaniclastic sequence, and volcanic rocks, as well local orogenic quartz veins. This large hydrothermal system could be co-genetic with a bimodal dike swarm mapped on the property and related to a buried fertile plutonic system, suggesting that geological structures and mineralization seen at surface are indicative of a Cu-Au porphyry system at depth”. Recommended activities to be conducted at the property over the next 2-3 months are completing the mapping and sampling on the areas of Caracahui, la Salada, Caracahui Norte and the Sonora Copper; mapping and channel sampling of the Cascabel and Guadalupe adits; dating studies of the plutonic rocks, prospection of the new areas generated by geochemistry (La Falsa, San Felix, and La Berrenda); and channel sampling on the Sonora Copper adit.
  • Almadex Minerals Ltd announced Q4, 2021 plans for its San Pedro project in Jalisco. The company reported that the property is fully permitted and is currently mobilizing a team and rig to site to conduct a drill testing prior to year-end.
  • Kootenay Silver Inc., reported results from the last six holes collared at its Columba project in Chihuahua.

    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.
