ON RESOURCES AND DEVELOPMENT

  • Atacama Copper Corporation and TCP1 Corporation announced a maiden resource estimate for theirs Cristina and Yécora projects located in Chihuahua and Sonora respectively. At Cristina project, Chihuahua, the companies estimated indicated resources of 17.5M tonnes of 0.51g/t Au, 34 g/t Ag, 0.5% Zn, 0.2% Pb, and 0.04% Cu (1.33 g/t AuEq) for a contained 752K Oz AuEq, and Inferred resources of 19M tonnes of 0.51 g/t Au, 27 g(/t Ag, 0.5% Zn, 0.2% Pb, and 0.05% Cu (1.27 g/t AuEq) for a contained 777K Oz AuEq.  The resource estimate is based on 220 diamond drill holes completed between 2010 and 2022 for approximately 70,000 m of drilling in total. Preliminary metallurgical test work suggests recoveries into concentrate of 75-85% for gold, 85-95% for silver, 80-90% for zinc and lead, and 70-80% for Cu. At Yécora project, Sonora, the companies estimated indicated resources of 25M tonnes of 0.30% Cu, 28 g/t Ag, and 749ppm Mo (0.79% CuEq9 for a contained 444M Lb CuEq, and inferred resources of 11.2M tonnes of 0.30% Cu, 24 g/t Ag, and 831 ppm Mo (0.78% CuEq for a contained 193M Lb CuEq. The resource estimate is based on 34 diamond drill holes and 8 reverse circulation drill holes completed between 2014 and 2022 for 14,006 m of drilling in total. Preliminary metallurgical test work projected a copper concentrate grade of 20-25% with a recovery of approximately 90% and containing 75 to 85% of the silver. The molybdenum concentrate grade was projected to be 50-55% with a recovery of 80 to 90%. Future testing will determine the feasibility of recovering lead and zinc to a separate concentrate, and thus zinc and lead were not included in the current resource estimate.
  • Torex Gold Resources Inc., provided a Q3, 2023 update on its Media Luna project, Guerrero. “Development of Media Luna continues to track well to plan, with first concentrate production remaining on track for late 2024 and commercial production in early 2025. At quarter-end, the Media Luna Project was 49% complete across engineering, procurement, underground development/construction, and surface construction. With 68% of upfront expenditures committed (including 42% incurred), expenditures to date have tracked reasonably well to the initial budget of $875 million, noting the stronger Mexican peso remains a headwind to manage. With $242 million incurred on the project year-to-date, project spending in 2023 is tracking toward the lower end of the annual guided range of $390 million to $440 million. Solid progress was made with respect to underground development and construction, which included another notable quarter of advance in the schedule-critical Guajes Tunnel and mobilization of the underground construction contractor. Breakthrough of the Guajes Tunnel is expected by year-end, three months ahead of schedule.  Significant progress was also made on the engineering front, which is expected to drive increased procurement activity through year-end. Surface construction continued with pad and foundation preparation for several key areas advanced during the quarter. The pace of construction is set to pick up in Q4 as concrete works ramp up, larger equipment deliveries to the south side commence with the completion of the Mazapa bypass road, and steel erection at the flotation plant begins before year-end.  The Media Luna Project is now soundly at the halfway mark and tracking to schedule and budget. With solid ongoing cash flow from El Limón Guajes and a healthy balance sheet with strong liquidity, we remain well positioned to execute on the remainder of the development plan over the next 15 months.”
  • Silver Tiger Metals Inc., filed a technical report to announce an updated mineral resource estimate (MRE) at its El Tigre project, Sonora. Table below shows the updated MRE for El Tigre project, Sonora:

  • Almaden Minerals Ltd., reported on two recent court decisions, both relating to the submission issued by Mexico´s Ministry of Economy to the second district court in Puebla. “As reported on February 22, April 13, and September 14, 2023, Economia made the Submission to the District Court seeking to deny the two mineral title applications which were first made by Almaden in 2002 and 2008. The Submission claims that the applications contain technical faults, despite Economia’s previous statements to the contrary and its acceptance of the mineral title applications and grant of the mineral titles in 2003 and 2009. By alleging technical faults in the mineral title applications, Economia appears to be arbitrarily seeking to deny the grant of the mineral titles and avoid the indigenous consultation ordered by the February 2022 decision of Mexico’s Supreme Court (SCJN). Such consultation would be welcomed by both the Company and surrounding community members. The two court decisions reported today are summarized as follow: The Federal Appeals court (TCC) dismisses all of the appeals filed by the Parties, including those of the  Company and supporting community members, and rules the Submission is compliant with the 2022 decision of the SCJN, since the SCJN decision did not formally prevent Economia from reviewing the technical aspects of the mineral title applications; The TCC ruling also does not address the validity of the Submission and therefore safeguards the Company’s right to challenge the substance and legality of the Submission through the Mexican Federal Administrative Court (TFJA);  As follow-up to the press release of September 14, 2023, the TFJA has now granted a definitive injunction in relation to the Submission, which prevents Economia from releasing the mineral rights covered by Almaden’s mineral title applications to third parties while the trial continues, anticipated to last 18 months”.

The table below shows the MRE for the Santo Tomas project:

Notes:

  1. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
  2. Table abbreviations include: % = percent, g/t = grams per metric tonne, Mlb = million pounds, Koz = thousand troy ounces.
  3. The mineral resources are reported at an effective cut-off grade (CoG) of 0.15% Cu.
  4. All figures are rounded to reflect the relative accuracy of the estimates. Totals in the above table may not sum or recalculate from related values in the table due to rounding of values in the table, reflecting fewer significant digits than were carried in the original calculations.
  5. The mineral resources exclude identified oxide mineralization due to a lack of confidence in recovery assumptions of oxidized tonnages at this phase of the Project.
  6. Metal assays are capped where appropriate. At the PEA level of the Project, it is the Company’s opinion that all the elements included in the copper equivalent calculation have a reasonable potential to be recovered and sold.
  7. All dollar amounts are presented in U.S. dollars.
  8. Bulk density is estimated on a block basis using specific gravity data collected on diamond drill core.
  9. Reasonable prospects of eventual economic extraction (RPEEE) are demonstrated through use of an economic pit shell based on long-term copper price of $4.00/lb, molybdenum price of $13.50/lb, a gold price of $1,700/oz, and a silver price of $22.50/oz. Metal recovery factors used in the determination of CoG and economic pit shell for Cu, Mo, Au, and Ag have been applied based on metallurgical recovery calculations based on average feed grade. A 45-degree slope angle was applied.
  10. The Huites Reservoir boundary was ignored for the purposes of mineral resource determination. This is consistent with the previous study.
  11. The economic CoG was calculated to be 0.11% Cu but for consistency with the previous study, Oroco has elected to use an effective CoG at 0.15% Cu. CoG assumptions include a copper price of $4.00/lb., mining cost of $2.27/t, processing costs of $4.23/t, G&A costs at $0.65/t, mine recovery at 98%, mean Cu recovery at 83.7%, and royalties at 1.5%, have been applied in consideration of the RPEEE.
  12. Equivalent Copper (CuEq) percent is calculated with the formula CuEq% = ((Cu grade * Cu recovery [83.7%] * Cu price) + (Mo grade * Mo recovery [59.1%] * Mo price) + (Au grade * Au recovery [58.6%] * Au price) + (Ag grade * Ag recovery [54.2%] * Ag price)) / (Cu price * Cu recovery [83.7%]). It assumed that the Santo Tomas Project would produce a conventional (flotation) copper concentrate product based on metal recoveries indicated by PEA metallurgical test work and mean Indicated Resource feed grades.
  13. Reported contained individual metals in the table above represent in-situ metal, calculated on a 100% recovery basis, except for CuEq% which applies mean recovery assumptions (see Note 12).
  • Gatos Silver Inc., announced filing of updated technical report on its Cerro Los Gatos Mine, Chihuahua.  The 2023 Technical Reports, titled “Mineral Resource and Mineral Reserve Update, Los Gatos Joint Venture, Chihuahua, Mexico” dated October 20, 2023, support the disclosure made by the Company in its September 6, 2023 press release announcing an updated Cerro Los Gatos mineral reserve, mineral resource, and life of mine plan.

ON MEXICO ISSUE

  • According to El Financiero, the mining sector has experienced a series of obstacles set by the current administration. The number of suspended projects stood at 439 in 2018, while the current figure is 837, representing a 69% increase in the number of suspended projects during the López Obrador administration. Likewise, the Fraser Institute of Canada placed Mexico in 37th place out of 83 countries evaluated, a drop of three places compared to 2021 and 17 positions compared to 2010. The sector is worried that the USD $77.2M budget assigned to Mexican Geological Survey (SGM) for 2024 is 95.47% below the USD $1.7 B private companies invested just in exploration. “With this lack of budget for exploration, they are condemning the country and the mining sector, because mining will be halted for another six years. If the modifications to the Mining Law remain as they are, we will witness Mexico’s mining sector entering a clear decline,” said Alfredo Phillips, Vice President, Argonaut Gold, in an interview with El Financiero.  In an interview with Mexico Business News (MBN), Ramón Luna, Director General of Servicios y Proyectos Mineros de Mexico (SPM), acknowledged that SGM has talented geologists and manages the most comprehensive database in Mexico. However, the public body does not match the infrastructure of a private company. “(The reform) would either force the more than 100 exploration companies in the country to work with the SGM or make the latter the only operator. This is not feasible because it lacks the necessary infrastructure,” he added.  Similarly, Raúl García, President of College of Mining Engineers, Metallurgists and Geologists of Mexico (CIMMGM), said that we could see the first impacts of lacking exploration by 2025 and a drop in production within the next five years, if SGM does not maintain the current levels of exploration. According to data from the Secretariat of Economy (SE), in 1Q23, the total foreign direct Investment (FDI) in the mining sector amounted to USD $419M. In contrast, during the same period in 2013, this figure reached USD $2.036 B, reflecting a decline of 79.4%. During Enrique Peña Nieto’s initial five-year term, from 2012 to 2017, the country received mining FDI totaling USD $2.8 B and USD $1.9 B, respectively, representing a decrease of 32.1%. Meanwhile, during the first five years of López Obrador’s administration, covering the period from 2018 to 2023, FDI amounted to USD $1.9 B and USD $419M, marking a significant 78% decrease. However, it is important to note that data for 2023 is not fully available, which means that the percentages provided could vary.
  • According to information from the US Geological Survey, there are 82 lithium deposits in 18 states of the Republic, which can represent 1.7 million tons. A few days ago, Héctor Usla, Economist and Reporter of the El Financiero Newspaper, reported that the 2024 Expenditure Law project plans to allocate MXP $9.77M to Litio para México (LitioMx), the entity created in August 2022, for the exploration, exploitation, benefit and use of lithium found in national territory. This is an amount that allows the administrative operation of the decentralized organization, but that seems insufficient to reliably establish the total amount of probable lithium reserves and initiate exploration and production in the most promising deposits. (Note of the writer.- Are you serious?…Obviously, it would be vastly insufficient to have a budget like that reported above to carry out exploration, exploitation, etc.).

ON EXPLORATION

ON MEXICO ISSUES

  • The United States government requested the installation of the first United States – Mexico – Canada Agreement (USMCA or T-MEC) labor panel under the Rapid Response Labor Mechanism (MLRR), for disagreeing with the Mexican government on the complaint against the San Martin Mine, of Grupo México, located in Zacatecas, who is accused of having impeded free unionization and authentic collective contracting. The Mexican government, for its part, responded that it would not review the case under the T-MEC mechanisms, arguing that the conflict dates back to 2007 (since the T-MEC entered into force in 2020) and that there is no evidence of that the mine exports to the United States, so it would not be a facility covered by the treaty. Grupo Mexico denounced that the union leader Napoleón Gómez Urrutia, presented the complaint that gave rise to this process with two objectives: “to have a new pretext to ignore the definitive award that condemns him to pay USD $55M plus accrued yields from 2005 to former mining workers and generate conflicts to press for a new political position that gives him jurisdiction / political privileges (“fuero politico”). After the lifting of the strike, in 2018, San Martin has received investments of more than USD $105M, has produced more than 1.25M tonnes of mineral each year and has generated about 1,300 jobs.
  • USMCA panel analyzes whether there was a violation in the case of the San Martin Mine, Zacatecas of Grupo Mexico. Given these facts, Grupo México indicated that it is essential for the San Martin Mine to put an end to a conflict that has harmed workers and their families for the last 15 years. Grupo México assured that the conflict in the San Martin Mine is not the product of the disagreement of the workers, but of the senator for Morena Napoleón Gómez Urrutia, who presented the complaint that gave rise to this process. “Urrutia sought to have a new pretext to ignore the final award that condemns him to pay USD $55M plus accrued income since 2005 to former mining workers, as well as generate conflicts to press for a new political position.
  • The president of the Business Coordinating Council (CCE), Francisco Cervantes pronounced on the request for a labor panel of the T-MEC in a mine of Grupo México. At the request of the United States government for the first panel of the Rapid Response Labor Mechanism under the Treaty between Mexico, the United States, and Canada at the San Martin mine of Grupo México, in Sombrerete, Zacatecas, Francisco Cervantes Díaz, president of the CCE, commented that it is a panel that has already lost a labor part here, that is why they are entering the issue in the United States and the resolution must be waited for. The Ministry of Economy indicated that Mexico rejected the request because this conflict dates from July 2007, and the law is not retroactive, since the “T-MEC would not be applicable to the facts related to this controversy.”
  • Grupo Mexico sees an impact beyond its San Martin Mine. The Mexican government will have the burden of proof to demonstrate in the T-MEC instance that there were no violations of union freedom in the San Martin Mine. If the case is lost, the sanctions could affect other company exports, beyond those originating from the facility in conflict, envisions the Grupo Mexico´s lawyer. It is worth remembering that the United States filed a labor complaint with the Mexican government accusing that, in the San Martin Mine, belonging to Grupo México, the rights of workers were violated because a strike was terminated by establishing a collective contract with another union, which would mean a violation of workers’ rights. Mexico maintained that this fact was prior to the entry into force of the trade agreement with the United States and Canada, and refused to carry out the investigation to determine a possible Remediation Plan for the company.

Preliminary rougher flotation tests of the Black Shale Zone recovered 91.1% copper, 98.2% lead, 98.8% zinc, 91.9% gold, and 98.4% silver (Overall Silver Equivalent Recovery – 98.1%);  preliminary rougher flotation tests of the Sulphide Zone recovered 94.2% copper, 95.3% lead, 97.6% zinc, 79.6% gold, and 96.0% silver (Overall Silver Equivalent Recovery – 95.7%);  surface Stockwork Zone column test extractions recovered – 83.1% Gold, 64.3% Silver at 3/8-in crush size with no requirement for agglomeration indicated in these tests (Overall Silver Equivalent Recovery – 78.1%; and also notable is the low cyanide consumption of 0.68 kg per tonne and lime consumption of 2.33 kg per tonne. “Previous drilling of the Surface Stockwork Zone has indicated a mineralized zone in excess of 100 meters true width. With high recoveries of 78.1% silver equivalency in column testing, simulating a heap leaching process, the Corporation sees the potential for an open pit low-cost heap leach process. This open pit heap leach process will be defined as part of the upcoming PEA”.
  • Impact Silver Corp., provided a construction update at its Plomosas mine in Chihuahua. “All necessary components of the mill have arrived on site or have been refurbished with assembly currently in the final stages. Testing and modification of the plant is expected to start in late summer, with ramp up to design capacity of nearly 200 tpd expected over the coming months. Construction is now approximately 85% complete. The Company has applied for the expansion of the current tailings pond which is expected to add at least an additional two years capacity. Meanwhile, an additional tailings pond is in the planning stages to accommodate years of future production and growth. Refurbishments to ventilation, electrical and lighting systems are ongoing as activity increases underground. Mining has begun and is expected to ramp up as the Company deploys additional equipment to the mine including scoop trams and underground trucks. Underground drilling to better define and expand resources has begun and drill permits for surface brownfield and green field exploration targets have been received. The exploration team has initiated its first phase of the 2023-2024 mine plan. This includes extraction of high-grade material in line with previous grades in excess of 13% Zn. There are currently 70 Company employees on site and another 25 contract workers. The Company is fortunate to have inherited a strong workforce after the acquisition closed and is adding positions in specific areas centred around engineering, exploration and day-to-day operations”.
