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”.

The Mining and Exploration News in Mexico: Highlights on the Fifth Week of September, 2021

By Jorge Cirett

During the 39th week of the year (September 27th to October 3rd, 2021), at least 20 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, one on financing and five more on project development or resource definition and one more on corporate matters. ON MEXICO ISSUES, Mexico’s government is looking for a law firm to represent its interests in international arbitration processes. A constitution amendment was proposed by the presidency of Mexico, to restrict the work of the private industry in the energy industry and to exclude private companies from the mining of lithium.   ON EXPLORATION, In Baja, One World Lithium is drilling at Salar del Diablo. In Sonora, Benjamin Hill Mining released assays from surface samples at the Benjamin Hill property. In Durango, Silverton Metals commenced exploration at the Pluton project; Silver Wolf Exploration released surface sample results for the Ana Maria project. In Zacatecas, Defiance silver is to start drilling the Lucita area on the Zacatecas project. In Oaxaca, Madoro Metals released radiometric ages on its Yautepec project.   ON MINING, No relevant news. ON FINANCING, Inomin closed a non-brokered private placement for $402.3 K in gross proceeds. ON RESOURCES AND DEVELOPMENT, GoGold Resources resources released drill results from the Mololoa area at its Los Ricos North project in Jalisco. Fabled Silver informed on drilling at its Santa Maria project in Chihuahua. Discovery Silver presented results from drilling at Cordero, in Chihuahua. Silver Dollar presented an update on La Joya, Durango. Silver Viper Minerals provided an update and drilling results from La Virginia, in Sonora. ON DEALS AND CORPORATE ISSUES, Altaley Mining engaged a group of consulting firms for financial publishing services and digital marketing services. ON SOCIAL RESPONSIBILITY, Capstone Gold informed on funding provided for sports in Zacatecas.

ON MEXICO ISSUES

  • Mexico’s government is looking for a law firm to represent its interests on international arbitration lawsuits, like the one brought by First Majestic Silver in the mining sector and Finley Resources, MWS Management and Prize Permanent Holdings on the oil services sector. Other relevant players that can initiate arbitration processes include Coeur Mining, AMERRA Capital Management, CMSA B. V., Contecon Manzanillo, Dal-Tile International, Doups Holdings, Gonzalo Mora Velarde and Jinlong Dongli Minera Internacional.
  • The Guerrero Gold Belt still has potential for 10 more million ounces of gold, according to David Jones, a geologist with extensive experience in the area. Torex Gold is to produce between 430 K to 470 K Oz Au in 2021 at its El Limon-Guajes mine, while Equinox expects to reach between 120 K to 140 K Oz Au, and both companies are in expansion development. Ana Paula is another known resource that can produce over 100 K Oz Au per year, in a belt with resources for more than 30 million ounces of gold. The state of Guerrero presents community and security issues that have to be addressed since the exploration stage, but that can be overcome, as the Los Filos and Guajes Limon mines demonstrate.
  • Mexico’s ejecutive power, president Andres Manuel Lopez Obrador presented an initiative that restricts the operations of private players in the electricity sector, and that also declares the government as the sole player in the mining of lithium (both measures reflecting a profound misunderstanding of economic processes, that is to erode into the country’s development rate and its inhabitants quality of life in the not so distant future, if approved).   

ON EXPLORATION

The Mining and Exploration News in Mexico: Highlights on the Second Week of July, 2021

By Jorge Cirett

During the 27th week of the year (July 5th to July 11th, 2021), at least 22 press releases were announced by companies working in Mexico. To note, six companies posted exploration advances on their properties, four on quarterly production and one about the end of an illegal blockade 17 months long, one posted on financing, five more on project development or resource definition and one posted an update on a law suite. ON MEXICO ISSUES, the illegal blockade on Americas Gold and Silver Cosalá operations in Sinaloa was terminated. Mexico has fallen 13 places on the Fraser’s Index on Mining Attractiveness, affected by perceptions on security and rule of law. ON EXPLORATION, in Sonora, Benjamin Hill Mining released surface assay results high in Cu and Au; Tocvan Ventures released results from RC drilling at Pilar. In Sinaloa, Brigadier Gold released drilling and underground sampling results from Picachos. In Durango, Canasil started drilling at Nora. In Zacatecas, Zacatecas Silver signed surface access agreements to the San Gill zone at its Zacatecas Silver project. In Oaxaca, Madoro Metals updated on exploration at Yautepec. ON MINING, GoGold Resources, Gatos Silver, Endeavour Silver and Torex Gold presented second quarter 2021 production results. Americas Gold and Silver signed an agreement with several ministries to reopen Its Cosalá operations in Sinaloa.  ON FINANCING, Gold79 Mines commenced trading on the OTCQB Venture Market in USA. Minaurum Gold closed a financing round for C$9.2 M. ON RESOURCES AND DEVELOPMENT, Southern Silver released drilling results from Cerro Las Minitas in Durango. GR Silver Mining, reported drill hole results from Plomosas in Sinaloa. Capitan Mining reported RC holes results from Peñoles, Durango. Guanajuato Silver provided drilling results from Pinguico, Guanajuato. Fabled Silver reported underground drilling results from Santa Maria, Chihuahua. ON DEALS AND CORPORATE ISSUES, Excellon Resources informed on a legal suite regarding the Miguel Auza mine in Zacatecas. ON SOCIAL RESPONSIBILITY, Fresnillo PLC, Minera Autlán and Newmont Peñasquito informed on activities supporting sports, the environment and community equipment in different localities.

ON MEXICO ISSUES

  • Mexico has fallen 13 places in the Fraser’s Index of Mining attractiveness from 2008 to 2020. Investment also saw a 42.8% reduction in the same period, including some effect by the pandemic. Security, labor regulations, political instability, lack of mining concessions and a nationalization streak in the current government were cited as deterrents to investment in the country. Those viewpoints are reflected in less investment, less employment and fewer opportunities to find new orebodies, factors that will lead to  reductions in production and taxes to be paid in the coming years.
  • The illegal blockade on Americas Gold and Silver Cosalá operations is off. After 17 months of illegal blockade, the negotiations aided by the federal government can hardly be called a success. Events like this one add to the deterioration on the global perception of Mexico as a good place for mining investment.
  • The AIMMGM (Asociación de Ingenieros de Minas, Metalurgista y Geólogos de México) stated through its president Sergio Almazán, that investment in the Mexican mining sector has been affect by the lack of certitude.

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.
