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 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 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.

By Miguel A Heredia

During the 24th week of the year (June 14th to June 20th, 2021), at least 15 press releases were announced by companies working in Mexico and 6 news published by the media, with seven reporting on resources and developments, five informing on exploration results, four commenting on Mexican issues, two announcing financial rounds, two discussing social issues, and one disclosing deals and corporate issues.  ON MEXICO ISSUES, Dhipna Yanssen Weichselbaum, head of the Federal Programs in Baja California explained that 12,000 people will be consulted in Mulegé to carry out the consultation of El Boleo. The Argentine Embassy in Mexico along with the Ministry of Mining of that country carried out a working seminar with the Mexican company Baluarte Minero (Industrias Peñoles and Fresnillo PLC). The consultation for the nationalization of lithium, proposed by President Andrés Manuel López Obrador, is not necessary, since, it is already owned by Mexico. ON EXPLORATION, In Sonora, Tocvan and its JV partner Colibri reported drill results from its the El Pilar project, and Tarachi started a second drilling program on its San Javier mining concession at La Colorada gold bearing breccia pipe. In Chihuahua, Mammoth reported results from an additional 1.7km of 3D geophysical modeling conducted at its Tenoriba project. In Nayarit, Sierra Madre provided an update on the activities developed at its Tepic project. ON MINING, no relevant news. ON FINANCING, Azucar granted stock options to certain directors and officers of the company (El Cobre project, Veracruz). Advance Gold closed a private placement financing for gross proceeds of $200K (Tabasqueña project, Zacatecas). ON RESOURCES AND DEVELOPMENT, Almaden completed a surface induced polarization geophysical (IP) program at its Ixtaca project in Puebla. GoGold released results from eight drill holes collared at its Los Ricos project in Jalisco. Silver Viper filed on SEDAR a NI 43-101 technical report supporting the maiden mineral resource estimate for its La Virginia project in Sonora. Torex released an updated mineral resource estimate for its media Luna project in Guerrero. Zacatecas Silver announced positive preliminary metallurgical test results from its Zacatecas Silver property. Excellon filed on SEDAR an independent NI 43-101 technical report for its La Platosa mine in Durango.

Peñoles and Fresnillo plc announced that they are training young Mexicans in seven states.

ON MEXICO ISSUES

  • Dhipna Yanssen Weichselbaum, head of the Federal Programs in Baja California explained that 12,000 people will be consulted in Mulegé to carry out the consultation of El Boleo. the procedure will consist of 2 phases: one is the publication of the call to know the expansion of the MIA project and then the citizen consultation that will take place in the communities of Santa Rosalía and San Ignacio, among others, which are related to the El Boleo mining company.
  • The Argentine Embassy in Mexico along with the Ministry of Mining of that country carried out a working seminar with the Mexican company Baluarte Minero (Industrias Peñoles and Fresnillo PLC). The group’s interest was particularly focused on the provinces of Neuquén, Rio Negro, Salta, Mendoza and San Juan, where Mexican businessmen expressed their intention to evaluate the possibility of investing in mining projects in the region. Technical experts and professionals from Baluarte Minero were informed about prospects for gold, silver, copper, potassium and lithium in Argentina.
  • According to experts of the Association of Mining Engineers, Metallurgists and Geologists of Mexico (AIMMGM), the consultation for the nationalization of lithium, proposed by President Andrés Manuel López Obrador, is not necessary, since, it is already owned by Mexico.

ON MEXICO ISSUES

  • No relevant news.

ON EXPLORATION

  • Benjamin Hill Mining Corp., released additional assays from 45 samples collected at the new La Salada East Area within its Benjamin Hill property in Sonora. Chip samples returned multiple results ranging from 1 g/t Au to 3.8 g/t Au with peaks of 10 g/t Au and 10.1 g/t Au. Gold values are associated with quartz veining and quartz breccias often with chalcopyrite, galena and hematite, limonite and “boxwork” pyrite. These results extend the known gold mineralization previously reported. The company also announced that it is finalizing drill program planning to test the most prospective targets generated to date and expects to receive drill permits in early June.
  • Silver Spruce Resources Inc., and its JV partner Colibri Resource Corporation commenced the 2,000m phase 1 exploration RC drilling at its Mezquite project in Sonora. Six holes are planned to drill test an area of 400m by 600m with elevated values to 3.41 g/t Au and 387 g/t Ag.
  • Heliostar Metals Limited presented results from its mapping and sampling program at its Oso Negro project in Sonora. High grade channel samples defined drill targets at the Prospecto Vein zone including 5.14 g/t Au, 953 g/t Ag, 1% Pb, and 1.9% Zn (1,428 g/t AgEq) over 1.2m; 2.55 g/t Au, 346 g/t Ag, 0.4% Pb, and 1.2% Zn (588 g/t AgEq) over 1.8m; and 3.29 g/t Au, 89 g/t Ag, 0.2% Pb, and 0.6% Zn (362 g/t AgEq) over 2.4m. This target has a length of 360m of strike, and has a weighted average grade of 420 g/t AgEq over and average width of 1.3m. Heliostar also announced the stacking of a new claim, Angel de Plata 2, increasing its land position to 120 square kilometers. Two new vein corridors have been discovered on the new claim with mine dump samples from historic workings up to 1,810 g/t AgEq.
  • Zacatecas Silver Corp., completed the first pass of its geological mapping and sampling program on the San Manuel Vein System. The company defined eight sets of oxidized, silver-base metal mineralized veins for over at least 3 km in length, with a dilation zone that is at least 600m wide. This extensional zone represents robust drill targets. The company has already commenced an environmental study at San Gill-San Manuel, concurrent with planning of first phase drilling at this target, which should be completed within 4 weeks.
