ON MEXICO ISSUES

  • Hermosillo, the capital city of the Sonora State, hosted the 14th International Mining Congress during October 18-21, 2022, with the participation of over 5,000 people.
  • The Mexican Mining Chamber (CAMIMEX) warned that thefts of output and goods like explosives in the mining industry continue to increase despite the support provided by the Secretary of National Defense (SEDENA). The General Director of CAMIMEX, Karen Flores, said that thefts remain a recurrent issue in the sector and highlighted that these crimes are probably perpetrated by organized crime.
  • According to data from the Ministry of Economy, the Mining Chamber of Mexico (Camimex) and experts, there is a mining collapse in Mexico since 822 mining projects were postponed, 180 foreign capital firms have left the country and there are 25 concessions stopped. If the policy were to change, 30% more jobs would be created and the contribution to Mexico’s GDP would increase by 0.5%, according to estimates. Mining and metallurgical activity exceeded tourism by 19% in foreign exchange generation. The president of the Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM), indicated that the uncertainty generated by this administration in the sector has caused a slowdown, which has left investments far from the more than USD $8 billion that were reached in previous years. GoGold Resources Inc., and GR Silver Mining Ltd., reported the best drilling intercepts in Mexico on the third week of October, 2022. Details are shown in the table below:

ON EXPLORATION

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.

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

  • The Ministry of Economy issued an informative note to correct what President López Obrador said about the expansion of the operations of the mining company El Boleo that operates in Baja California Sur. The mining and metallurgical company is seeking an expansion in the surface of its operations and not a new concession as stated by the president. In July 2019, El Boleo requested an expansion of its environmental impact statement, in which it requested an expansion of its mine by 446 hectares contiguous to its current operation. They indicated that this is because the life of the main mine is running out and its mineral reserves are in this adjoining land. The statement indicates that the mining project began construction in December 2010, with an investment of USD $1,717M, and began production in 2015. The company produces copper, cobalt, zinc and manganese. Currently, the mining company employs 1,282 direct jobs (836 unionized and 446 trusted).
  • Fernando Alanís, president of the Mining Chamber of Mexico (Camimex), stated that the mining industry in Mexico paid MXP $30,374M in taxes during 2020. He also highlighted that those that refer to the fact that the industry pays little are myths, as he highlighted that around 10.6% of the Gross Domestic Product generated by the industry is destined to the payment of taxes, higher than the 7.6% of the manufacturing industry, or the 6.1% of the electricity sector. Fernando Alanis detailed that of the total taxes paid, MXP $24,205M are for Income Tax (ISR), while there are MXP $2,576M in surface rights and MXP $3,593M in new rights.
  • The Mining Chamber of Mexico (Camimex) stressed that mining is a tractor industry that, in addition to boosting the regional economy, supports the development of other economic activities. It drives construction with average annual investments of USD $5B a year. The same occurs with the transport of materials, by promoting the movement of 8.7M tons per year that travel 100.2million kilometers on the roads (78%) and railways (22%) of Mexico. It also boosts port activity, with the export and import of 474M tonnes of materials per year. In total, the transportation costs of mining companies in Mexico total USD $245M per year. Through the mining clusters (Zacatecas, Sonora, Chihuahua, Guerrero and Sinaloa) a local supply has been developed that amounts to 9,700 national supplier companies, 90% of which are small and medium-sized enterprises (SMEs). For Mexico, the mining industry is an outstanding generator of income, contributing 8.3% to the industrial GDP and 2.5% to the national GDP. It is also a large generator of jobs, with more than 379,000 direct jobs and almost 2 million indirect jobs.
  • The Mexican mining industry called on the environmental authorities to hold a dialogue to understand the reasons why the permits are being stopped and to work together to unlock authorizations for Environmental Impact Manifestations (MIAs) that are being held at the Ministry of the Environment and Natural Resources which have stopped several mining projects in the country. Mining in Mexico has a robust environmental legislation that is permanently addressed, among which the General Law of Equilibrium and the Environmental Protection, as well as seven Official Mexican Standards and the general regulation that exists for activity in protected natural areas in Mexico, among others.
  • Representatives of the Mexican Mining industry asked the federal government to reactivate mineral concessions to increase investments in the sector. No new mining concessions have been granted in the country since 2019 and the effects of this were reflected in a lower Foreign Direct Investment in the sector.
