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”.

ON MEXICO ISSUE

  • President of the College of Mining Engineers, Metallurgists and Geologists of Mexico (CIMMGM), assured that, although there are promising geological signs in Chihuahua, Coahuila, Zacatecas, Oaxaca, Guerrero and Guanajuato, the Mining Law limits exploration of ‘rare earths’ in Mexico. The lack of formal exploration work imposed by the new legislation leaves Mexico at risk of becoming dependent on China, which controls 90 percent of global rare earth production. This is because the only one that can carry out exploration in Mexico is the Mexican Geological Service (SGM), which has reduced the interest of private parties to search for these minerals. For next year, the Secretariat of Finance and Public Credit (SHCP) granted the SGM a budget of MXP $1,320M, just MXP $127M more in relation to the MXP $1,193M that were granted for 2023, a budget that, they assure, will be insufficient. SGM explained that, if they do not have more budget, it will be difficult for them to meet the new mandates assigned to them by the Ministry of Economy, so, until now, they said, the most viable thing will be to work hand in hand with private sector.

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:

  • Newmont Corporation announced end of strike at its Peñasquito Mine in Zacatecas, and now is focused on a safe return-to-work plan and a quick ramp up of operations while strengthening workforce relationships. On October 13, 2023, Newmont and the Union submitted the Agreement to the Mexican Labor Court, which gave its approval, thus ending the strike. “In 2022, Peñasquito contributed USD $1.9 B in economic value to Mexico, including USD $643M in employee wages and benefits, taxes, and royalty payments to federal, state, and local governments, and investments in community infrastructure and water projects. Minera Peñasquito is the second largest employer in Zacatecas, Mexico with a workforce of more than 5,000 individuals. The mine supports another 28,000 people and their families, in neighboring communities and across the country, who are part of the mine’s local and national supply chain”.
  • 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”. (Ixtaca project, Puebla).

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 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.
  • GoGold Resources Inc., Sierra Metals Inc., Vizsla Silver Corporation, and Guanajuato Silver Company Ltd., reported the best drilling intercepts in Mexico on the fourth week of August, 2023. Details are shown in the table below:

With short weapons, machetes and bats, people identified as related to the Morenista senator Napoleón Gómez Urrutia seized the town of Hércules, in Coahuila, a place of little more than 8 thousand inhabitants that was generated around the operations of extraction of iron from Minera Del Norte, a subsidiary of Altos Hornos de México (AHMSA). In a statement, the Mining Union indicated that the conflict occurred after a group majority of workers from Minera Del Norte and AHMSA decided to abandon the organization headed by Gómez Urrutia to join the National Democratic Union of Miners, and he has responded the same as he did in Zacatecas, Guerrero, Sonora and other areas, generating violence and stopping the activities of the mining companies. Minera Del Norte is the main iron extraction company in the region; all the material extracted by the workers is sent to Monclova through a 300 kilometer railway, for use as an input in the AHMSA smelting furnaces.

ON EXPLORATION

  • Prismo Metals Inc., released trenching sampling results from its Los Pavitos project in Sonora. Highlights assays include ZA2 (Auras Zone)  with 2.2 g/t Au and 23 g/t Ag over 19m long, including 10.3g/t Au and 104 g/t Ag over 4m long; ZSC9 (Santa Cruz Zone) with 0.5 g/t Au over 8m long; and ZSC10 with 2.3 g/t Au and 13 g/t Ag over 7.8m long. The company intends to explore these mineralized zones by drilling, planned to commence shortly.
  • Colibri Resource Corporation outlined mineralized structures on the Banco de Oro and Bonancita target areas at its the Plomo project in Sonora. At the Banco de Oro target, the mineralization consists of brecciated quartz veins hosted in foliated sericitized and pyrite bearing rhyolites. Recent geological mapping and sampling has covered an area of approximately 41 hectares, extending approximately 500m north of the historic Banco de Oro mine. Gold values were detected in 46 of the 64 analyzed samples, of which 14 samples returned >0.1 g/t Au, with a high grade of 1.45 g/t Au. At the Bonancita target, mineralization consists of four prospects, all of which contain historical assays from outcrop samples returning > 1 g/t Au. Three of the prospects, Bonancita, Bonancita NWI and Bonancita NWII form a NW trend approximately 2 km in length which is coincident with both a strong topographic lineament and with a strong, NW trending, regional scale magnetic gradient lineament. The recent geological mapping and sampling was conducted on the southernmost prospect, where the objective was to evaluate a NW mineralized trend defined by historical sampling including a high value of 7.62 g/t Au. The exploration program covered over 60 hectares and a total of 75 samples were collected for gold analyses, of which 15 samples returned > 0.1 g/t Au and 3 returned > 1 g/t Au with a peak value of 2.72 g/t Au.
