ON MEXICO ISSUE

  • Analysts predict that the fourth quarter of 2023 will be a mixed bag for Mexican mining companies due to pressures on costs and falling prices of industrial metals. While some companies may benefit from increasing prices of precious metals like gold and silver, others will also face higher costs. Grupo Mexico has already reported weak financial results due to decreased sales of copper, while the other companies are expected to face similar challenges in 2024 due to China’s economic slowdown. Only Minera Frisco has generated a positive return so far this year among the four mining companies. Autlán is expected to make some sequential improvements due to cost-cutting efforts, but the industry as a whole is predicted to face challenges in the coming year. All of last year, only the companies that are part of the S&P/BMV stock index IPC Grupo México (+37.66%) and Peñoles (+3.58%) had gains on the Stock Market. While the share of Fresnillo, a subsidiary of Peñoles listed on the London Stock Exchange, lost 34.08%, that of Autlán lost 26.43% and that of Frisco lost 9.01%.
  • President Andrés Manuel López Obrador (AMLO) has presented 20 proposals for constitutional reforms in Mexico. One of the proposals is to return the Comisión Federal de Electricidad (CFE) to its status as a public, strategic, and nationally important company.  AMLO also proposes to prohibit the extraction of hydrocarbons through hydraulic fracturing (fracking) and to not grant concessions to private companies for open-pit mining activities. However, in the economic budget planned for 2024, the government has contemplated two projects with fracking for MXP $4.63M, according to data from the organization Mexican Alliance against Fracking (AMCF). Currently, of the almost 250 mines that operate in the country, 97 are open pit metal mines and 152 more are underground mines; However, until March 2022, 15,551 mining concessions were registered in the country with validity after 2050. It should be noted that since the arrival of AMLO to the presidency, not a single mining concession has been granted, which has led the sector to have a drop in investment that decreased its participation in the national GDP, from 2.50 in 2021 to 2.46 percent in 2022, while in industrial GDP from 8.78% to 8.63%. The proposed reforms also aim to eliminate “costly and elitist” dependencies and organizations that were supposedly autonomous but disconnected from the interests of the people. Some of the autonomous bodies that could be affected by these proposals include the Comisión Reguladora de Energía (CRE), Comisión Nacional de Hidrocarburos (CNH), and Comisión Federal de Competencia Económica (COFECE). AMLO will submit these initiatives to the Chamber of Deputies for discussion in the current or next legislative session.
  • President Andrés Manuel López (AMLO) presented initiative to prohibit open pit mining. On February 5, on the anniversary of the Political Constitution of the United Mexican States, AMLO presented an Initiative with a Draft Decree to carry out various reforms, one of these being the prohibition of open pit mining. According to the initiative, addressed to Dip. Marcela Guerra Castillo, President of the Chamber of Deputies, in order to protect the environment and health, we seek to modify art. 27 constitutional to “prohibit both the granting of concessions and the activities of exploration, exploitation, benefit, use or exploitation of minerals, metals or metalloids in the open pit, with the addition that the people who carry out these activities will be sanctioned.” The AMLO project indicates that there are currently around 264 open pit mines in Mexico, and much emphasis is placed on the old vision of predatory mining, leaving aside that for a mine to operate in our country it must have more than a thousand rules and regulations, in addition to having comprehensive closure plans.
  • Orla Mining Ltd., First Majestic Silver Corp., Prismo Metals Inc., and Prime Mining Corp., reported the best drilling intercepts in Mexico on the second week of February, 2024. Details are shown in the table below:

ON EXPLORATION

  • Prismo Metals Inc., provided an exploration update on its Palos Verdes project in Sinaloa.  Following the completion of its third drill campaign with 2,923 meters drilled in 15 holes, and in preparation of the upcoming expanded drill program to be drilled from Vizsla Silver Corp, Prismo completed an alteration and geochemical study that confirmed a downward offset of the mineralized ore shoot defined by drilling to date and that a second blind mineralized shoot may exist to the northeastern portion of the Palos Verdes vein, based on a geochemical sampling which revealed high-grade silver, gold, zinc, and lead values in the vein system.  The best sample from this program assayed 930 g/t silver and 10.55 g/t gold with 15.4% zinc and 4.5% lead (2,605 g/t Ag/Eq) over 0.5m. The company plans to conduct deep drilling from Vizsla Silver’s ground to explore these concepts further.
  • Silver Dollar Resources Inc., acquired from Canasil a 100% interest in the Nora project in Durango, and provided a project update. In connection with the acquisition of the Nora property, Silver Dollar encountered certain unresolved discrepancies in verifying the 2020 and 2021 drill results Canasil reported on the Nora property. For gold: of the 157 samples duplicated, Canasil reported 42 samples >1 g/t Au (1.23 – 43.7 g/t) including 18 samples >5 g/t (5.3 – 43.7 g/t), whereas Silver Dollar’s re-assaying yielded only three samples >1 g/t Au (1.04, 1.75, and 2.30 g/t). For silver: of the 157 samples duplicated, Canasil reported 44 samples >200 g/t Ag (133 -1,924 g/t) including 19 samples >500 g/t Ag (504 – 1,925 g/t), whereas Silver Dollar’s re-assaying yielded only three samples >100 g/t Ag (129, 158, and 448 g/t). “The QPs from both companies discussed the situation and recommended a further analytical program be carried out to provide some insight into what may have caused the assay discrepancies. However, Canasil did not have the financial resources to contribute to the recommended program and alternatively offered to waive certain of Silver Dollar’s consideration obligations under the Nora Option Agreement and transfer 100% ownership of the Nora property to Silver Dollar for the consideration that has been provided to date (as detailed below), subject to a 2% net smelter returns royalty with Silver Dollar having the right to buy back 1% of the Royalty for $1M. As of the date hereof, Silver Dollar has incurred a total of approximately $134,779 in exploration expenditures on the Nora property, as full consideration for the acquisition thereof. Silver Dollar is not required to provide any further consideration to Canasil to complete the acquisition and the transfer of the Nora concessions to Silver Dollar has been initiated”.

  • Chesapeake Gold Corp., provided a metallurgical and mineralogical update for its Metates deposit in Durango.  The latest results from this phase of metallurgical testwork are very encouraging. “A systematic, methodological approach individually testing several parameters under different conditions is being undertaken in 42 columns. The results have identified certain parameters that provide the conditions where the leach technology oxidizes mineralization at a faster rate than our previous testwork. Under these conditions, we believe the targeted oxidation curve will be achieved and provide the foundation for preparing the pre-feasibility study early next year”. “Chesapeake will continue to advance the metallurgical program. As the columns meet the oxidation curve target and switch to cyanide leaching, additional columns will be loaded and tested to confirm the improved oxidation rates. At the completion of this process, the results will be released outlining the oxidative curves and precious metal recoveries through cyanide leaching. Once sufficient metallurgical work is available, management plans to commence a pre-feasibility study to further de-risk Metates and advance the project toward our goal of developing one of America’s largest gold and silver deposits”.
  • Heliostar Metals Ltd., released drill results of three new holes completed, expanded the limits of the High Grade Panel, and defined new growth targets at its Ana Paula project in Guerrero.
