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.
  • Torex Gold Resources Inc., Endeavour Silver Corp., and Vizsla Silver Corp., reported their best drilling intercepts in Mexico on the third week of November, 2023. Details are shown in the table below:

  • Guanajuato Silver Company Ltd., initiated processing of mineralized material from an existing stock pile at its El Horcon mine, Guanajuato. The company has shipped and processed 350 tonnes of material from the historical stockpile. Head grades from different batches of this material were approximately 30-50 g/t Ag and 1.6 to 3.0 g/t Au, with initial processing runs given recoveries of approximately 70% for Ag and 82% for Au. “The Horcon stockpile is expected to add approximately 4,000 tonnes of mineralized material per month over a six-to-ten-month period. Metallurgical testing of the mineralized material at Horcon has been demonstrated compatible with the Cata mill processing circuit and is currently being blended with mineralized production from the Valenciana Mines Complex”.
  • Heliostar Metals Ltd., announced updated Mineral Resource Estimate for its Ana Paula project, Guerrero. Highlights of the Mineral Resource Estimate include a total measured and indicated mineral resources of 710,920 Oz Au grading 6.6 g/t Au; a total of inferred mineral resource of 447,512 Oz Au grading 4.21 g/t Au; a mineral resource estimation cutoff grade of 2.5 g/t Au increased from previous estimate; a connected zone of greater than 2ooK Oz Au grading greater than 10 g/t Au within the measured resource in the High Grade Panel that can be targeted in the initial years of mining; a 58% increase in measured and 30% increase in indicated gold grade relative to the previous resource estimate at same 2.5 g/t cutoff grades. On the other hand, a tighter spaced drilling has led to resource grade growth which is a positive indication for additional grade increases during conversation of the inferred resources to higher classifications; has increased in inferred ounces due to stricter estimation with a view to underground mining; the High Grade Panel at core of the resource is now 280m long, 100m high, and 60m thick; and this new resource has been delivered  at an all-in discovery cost of USD $16 per new Oz Au, inclusive of all exploration and project costs.
  • Tocvan Ventures Corp., poured the first doré bar of gold and silver from bulk sample material processed at its Pilar project, Sonora. The bar weighs 1.487 kilograms in total, with assays from local certified laboratory LTM returning 18% of gold and 69% of silver.

Drilling highlights include holes ML23-965 with 1.63 g/t Au, 13 g/t Ag, and 0.48% Cu (2.55 g/t AuEq) over 6.85m, plus 4.42 g/t Au, 1 g/t Ag, and 0.04% Cu (4.50 g/t AuEq) over 2.96m; hole ML23-970A with 2.81 g/t Au, 27 g/t Ag, and 0.31% Cu (3.62 g/t AuEq) over 5m; and hole ML23-986A with 27.50 g/t Au, 28 g/t Ag, and 1.2% Cu (29.76 g/t AuEq) over 14.1m. “The current distribution of the multiple intercepts confirms a north-south extension of more than 600 m with a width similar to the EPO deposit, which suggests Media Luna West could have a similar mineralized potential to that of EPO. The exploration potential of this structural corridor is open to the north and is likely favored by intersecting with the swarm of east-west dykes that define the best mineralization trap within both the nearby Media Luna and EPO deposits”.
  • Mammoth Resources Corp., announced results of an independent drill hole spacing analysis with recommendations to identify initial Mineral Resource Estimate (MRE) at its Tenoriba project, Chihuahua. The independent analysis recommended  drill hole spacing for the El Moreno, Masuparia, and Los Carneritos targets of 80m, 40m, and 80m respectively, for an Inferred MRE.
  • Oroco Resource Corp., filed an independently prepared Preliminary Economic Assessment (PEA) for its Santo Tomas project in Sinaloa. The report dated October 11, 2023 and titled “Santo Tomas Copper Project NI 43-101 Technical Report and Preliminary Economic Assessment”, has been prepared in accordance with National Instrument 43-101 – Standards of Disclosure of Mineral Projects.  Results of the PEA were previously announced in the Company’s news release dated October 17, 2023.  There are no differences in the Report from those results previously reported.

ON MEXICO ISSUE

  • 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).
