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”.

By Jorge Cirett

During the 34th week of the year (August 30th to September 5th, 2021), at least 21 press releases were announced by companies working in Mexico. To note, four companies posted exploration advances on their properties, four posted on mining or quarterly reports, seven on financing or shares and four more on project development or resource definition. ON MEXICO ISSUES, Camimex informed on direct and indirect employment generated by the mining industry. In 2020, Mexico was the top silver producer in the world. Sixty percent of foreign held mining projects are idle. Mexico is the ninth top producer of gold in the world, with 41.3 tonnes produced in 2020. ON EXPLORATION, in Chihuahua, Monarca Minerals completed the first two RC holes at San Jose. In Sinaloa, Vizsla Silver released results from 19 holes on the Naploleon area of the Panuco project. Durango, Canasil Resources released results from two diamond holes at Nora. In Guanajuato, Guanajuato Silver informed drilling continues at Pinguico.  ON MINING, Altaley Mining and Santacruz Silver reported second quarter 2021 results. Torex Gold released its multi-year production outlook for el Limon Guajes complex, aiming to produce 1.59 to 1.75 M Oz Au in 2021-2024. Guanajuato Silver commenced infill drilling at El Cubo. ON FINANCING, Prime Mining reported the exercise of warrants for C$9.5 M; Silver Spruce announced a financing round for up to $1 M; Mithril plans to raise up to A$3.3 M. Silver Wolf shares are now eligible for electronic clearing in the USA. SilverCrest completed the second scheduled drawdown of US$30 M.

ON MEXICO ISSUES

  • Camimex (Cámara Minera de México) informed that during the first half of 2021 the mining industry generated 40,895 new direct jobs and more than 2 million new indirect jobs, boasting salaries 36% higher than the national average.  Also, during 2020 the industry invested US$3,532 M (US$3.5 billion, in American notation) and is posed to invest further US$5,034 M (US$5 billion in American notation) in 2021 and a total of more than US$24,000 M (US$24 billion in American notation) in the next six years.  
  • Mexico was the top producer of silver in the world in 2020, with 5,541 tonnes, China and Peru stand in the second and third place producing 3,443 tonnes and 2,991 tonnes respectively.
  • There are 1,190 mining projects funded by foreign capital in Mexico, but 6 of each 10 are idle, regardless of the increase in metal prices. Of the 1,190 projects, 754 are idle, 307 in exploration, 78 in production, 43 in development and 8 have closed. One of the issues affecting the mining industry in Mexico is the fiscal load, with taxes on profit of 52.7%, same tax burden that in other countries is lower: USA 30.2%, Canada 34.6%, Chile 35.7%, Peru 39.9%.
  • Mexico is the ninth producer of gold in the world, tied with Uzbekistan. Gold production during the first half of 2021 was 41,325 kg, which is 30% higher than a year before. This is the first yearly increase in gold production since the historic high of 2015, when 60,325 kg were produced. Sonora produced 29.8% of the total amount, Zacatecas 18.8% and Chihuahua 16.1%.

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 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.

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.
  • Camimex released a table with the Mexican Mining Developments programmed for the next few years, same that reach US$7,820 Million in investment (Mexican number notation, equivalent to US$7.8 billion).
