The Mining and Exploration News in Mexico: Highlights on the Fourth Week of September 2023

By Jorge Cirett
During the 39th week of the year (September 25th to October 1st, 2023), only 11 companies working in Mexico posted news releases (the weekly low record is nine, since 2015). One company reported exploration on one of its properties, while no news on mining were released. Five companies informed on the opening or closing of private placements, their assistance to investor conferences and/or the amendment of credit facilities. One company presented drilling results from one of its properties and one other an updated mineral resource estimation on one of its mines. The government cancelled nine mining concessions to one company in Sonora. One company updated on results of its annual general meeting and one other informed on modifications to streaming amendments. ON MEXICO ISSUES, the federal government is playing all tricks available on its hat to get the Sonora Lithium deposit under its control, expropriating mining concessions without calling it an expropriation, of what they see as a project with a potential large income revenue and a stepping stone on resources sovereignty. Camimex regards the cancellation infeasible while pointing that exploration expenditure has fallen 40% in recent years. A Labor Panel has been installed under T-MEC to review the US claim against Grupo Mexico in one of its mining units. ON EXPLORATION, In Chihuahua, Kootenay Silver informed four drill holes have been completed at Columba. ON MINING, no relevant news. ON FINANCING, Aztec Minerals closed the final tranche of a private placement for C$639 K, GR Silver was granted an extension for its financing placement, Regency Silver completed the first tranche of an upsized private placement. ON RESOURCES AND DEVELOPMENT, Heliostar Metals reported drilling results from Ana Paula, in Guerrero. Guanajuato Silver presented an updated resource estimate for San Ignacio, in Guanajuato. ON DEALS AND CORPORATE ISSUES, the Mexican government cancelled nine mining concessions to Ganfeng’s Lithium in Sonora, in an unscrupulous bid to get its hands on the only defined lithium resource in Mexico. Southern Silver provided an update on results from its AGM. Bear Creek Mining presented two press releases to inform on changes on the two streaming agreements on the Mercedes mine production in Sonora. ON SOCIAL RESPONSIBILITY, no relevant news.
ON MEXICO ISSUES
- Camimex (Cámara Minera de México) regards the cancellation of Ganfenfg Lithium’s concessions in Sonora as not viable. Ganfeng was served in August with the cancellation notice by the government on grounds of lack of investment, which the company denies. The exploration expenditure in México has fallen close to 40% in the last seven years.
- Ganfeng’s Lithium cancelation of claims in Sonora by the federal government will have to be dealt with in national courts, as Mexico and China do not count with a trade agreement.
- Marath Bolaños, head of the Secretaría del Trabajo y Previsión Social (Labor Bureau) stated that the Labor Panel under the T-MEC has been formed, to review the controversy between the US government and Grupo Mexico’s San Martín mine in Zacatecas.
- The president of Mexico indicated that its government is reviewing lithium mining concessions.
ON EXPLORATION
- Kootenay Silver Inc. updated on drilling progress of their program at Columba, in Chihuahua. Four diamond holes have been completed of the expected 12-15 holes in the 3,000 m program. “Analyses are awaited, however visual confirmation of mineralization and veining typical of D-Vein has been reported by the logging geologists in the holes to date where modeling predicted. Veining and associated stockwork mineralization in drilled length in each hole was observed to measure approximately 5.0 m vein/ stockwork, 8.2 m vein and 23 m stockwork, 10 m vein and 26 m stockwork and 1.0 m vein, 3.0 m stockwork in holes CDH-23-136 through CDH-23-139 respectively”.
ON MINING
- No Relevant News.
ON FINANCING
- Aztec Minerals Corp. closed the second and final tranche of its non-brokered private placement for gross proceeds of CAD$639.1 K. Aggregate gross proceeds from both tranches are CAD$1.55 M. Alamos Gold Inc. participated in the financing with $140.6 K (Cervantes, Sonora).
- Capstone Copper Corp. amended its existing revolving credit facility to increase the aggregate commitments from $600 M to $700 M “and extend the maturity from May 2026 to September 2027. The Amended Credit Facility will bear interest on a sliding scale of adjusted term SOFR plus a margin of 2.000% to 2.875%”. Capstone cash and cash equivalents position by the end of June 2023 was $520 M (Cozamin, Zacatecas).
- GR Silver Mining Ltd. was granted an extension by the TSX Venture Exchange to complete its non-brokered private placement for gross proceeds of up to $1 M. A first tranche of $329 K in gross proceeds was closed on August 10, 2023 (Plomosas, Sinaloa).
- Regency Silver Corp. completed the first tranche of a previously announced private placement, which has been upsized to C$1.75 M from C$1.5 M (Dios Padre, Sonora).
- Vortex Metals Inc. will be participating in the 23rd Investment Conference organized by CM-Equity AG in Munich (Riqueza Marina, Oaxaca).
ON RESOURCES AND DEVELOPMENT
- Heliostar Metals Ltd. reported drilling results from the Ana Paula project in Guerrero. These two infill holes are within the “High Grade Panel” at the deposit, and are the last that are to be included in the resource update planned for November 2023. Highlighted core length intercepts comprise 35.9 m @ 8.17 gpt Au (including (11.8 m @ 13.55 gpt Au); 83.6 m @ 8.57 gpt Au (including 63.0 m @ 10.41 gpt Au, which includes 12.0 m @ 18.36 gpt Au); 57.0 m @ 6.03 gpt Au (including 5.0 m @ 45.44 gpt Au); 14.6 m @ 32.98 gpt Au (or 18.60 gpt Au if assays cut to 100 gpt Au).
- Guanajuato Silver Company Ltd. presented a new mineral resource estimate for its San Ignacio mine in Guanajuato. Measured and indicated resources comprise 790 K tonnes @ 123 gpt Ag, 2.10 gpt Au, containing 3.14 M Oz Ag, 53,000 Oz Au, and inferred resources of 2.17 M tonnes @ 127 gpt Ag, 2.27 gpt Au, containing 8.9 M Oz Ag, 158,000 Oz Au. “… an increase of 130% in the measured & indicated category and 283% in the inferred category.”
ON DEALS AND CORPORATE ISSUES
- The Mexican government, through the Direccion General de Minas (DGM) cancelled nine mining concessions in Sonora to Ganfeng Lithium, including those where the largest (and so far, the only) lithium deposit in Mexico is located. The company was informed of the cancellation last August, with the government stating that the minimum investment required between 2017 and 2021 was not fulfilled and Ganfeng declaring its compliance above that limit. The company has already filed claims against the resolution at the Economy Secretariat (Secretaría de Economía). Note by editor. – This is one more issue between private capital and the Mexican government, with a president with a world vision from the 1970’s, where the State is to have a ruling fist on all economic activities, and the president a final saying on what is to be done or not.
- Southern Silver Exploration Corp. provided a corporate update from the company’s annual meeting. During the meeting seven incumbent directors were elected and the chartered accountants reappointed. Lawrence Page, Robert Macdonald and Killian Ruby were reappointed as president, vice president exploration and chief financial officer respectively. (Cerro Las Minitas, Durango).

Ltd. which was assumed upon the acquisition of the Mercedes mine, in Sonora, in April 2022. As a result, over 300 additional ounces of gold produced at Mercedes per month will now be fully available for sale by the Company. A promissory with 1368445 B.C. Ltd. was amended to extend the maturity from the end of September 2023 to the end of November 2023.
- Bear Creek Mining Corp. announced a restructuring of its current stream and debt obligations with Sandstorm Gold Ltd. to improve the Mercedes mine ability to produce free cash flow near term by reducing near-term Au and Ag stream delivery obligations and the refinancing and extensions of Bear Creek’s debt with Sandstorm. Sandstorm will refinance its US$22.5 M convertible debenture into a 5-year convertible promissory note at 7% per year and convertible into Bear Creek shares at C$0.73 per share. “Sandstorm has agreed to make up to US$8 million in additional credit” prior to the end of August 2024. Bear Creek has to complete an equity financing to raise at least CAD$9.5 M.

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
- Southern Empire Resources Corp., received permitting from the Mexico´s Ministry of Environment and Natural Resources (SEMARNAT) for 30 drill hole sites at its Centauro project in Chihuahua. “The Centauro Gold Project exhibits significant potential to host “Carlin-style” and/or epithermal precious metal mineralization based on extensive brecciation, silicification and argillization of the Tertiary-age Ahuichila Formation conglomerate, a strongly coincident gold (“Au”), arsenic (“As”), antimony (“Sb”), mercury (“Hg”), thallium, silver, barium soil geochemical signature associated with a silicified mesa “cap” covering 2.5 km along the strike of the main zone, outcrops containing arsenopyrite, realgar, orpiment and stibnite, and low to non- anomalous base metal values”.
- Radius Gold Inc., provided an update on drilling at its Tropico project in Zacatecas. The initial hole TDD-001 plan for 300m to intersect the Tropico breccia pipe encountered difficult ground conditions and was abandoned at 56m. “The hole from 19m to 56m is intensely altered with clay, silicification, variable zones of hydrothermal breccias and repeated sets of banded silica veins with fine sulphides and stockwork veining. Banded veining had not previously been seen on the property”. “The drill rig has been stepped back from the target an additional 25m and a new hole drilled deeper under hole TDD-001, this time using large diameter PQ sized core and casing which is expected to alleviate the drilling difficulties”.
ON MINING
- No relevant news.
ON FINANCING
- Equinox Gold Corp., announced that it has entered into an agreement to buy, on a bought deal basis, 4.75% unsecured convertible senior notes due 2028 in an aggregate principal amount of $150M. The company has granted the initial purchasers up to an additional $22.5M aggregate principal amount of notes. The notes will be issued at par value. Later on, the company announced that it had closed its previously announced bought deal offering of $172.5M aggregate principal amount of 4.75% unsecured convertible senior notes due 2028, which includes exercise of the full amount of the option to purchase an additional $22.5M aggregate principal amount of notes Net proceeds will be used for repayment of debt and for general corporate purposes (Mina Los Filos, Guerrero).
- Excellon Resources Inc., announced debenture restructuring to reduce the outstanding principal amount to CAD $7.5M representing a reduction of CAD $10.4M (58% reduction), and to amend the terms of the remaining debentures to, among other things, further extend the maturity date to August 31, 2026. In exchange for CAD $10.4M aggregate principal amount of the debentures, Excellon to pay CAD $3.5M in equity, 25% interest in Silver City Project, plus additional non-dilutive contingency and royalty payments (La Negra Mine, Queretaro).
ON RESOURCES AND DEVELOPMENT
- Golden Tag Resources Ltd., announced the commencement of a 7,000m drilling campaign at its La Parrilla Mine Complex in Durango. The 7,000m phase 1 drilling program will focus on infill and step-out drilling in proximity to underground mining infrastructure and existing development in three key areas: a) Rosarios and Cuerpo 340 Veins (3,000 m of drilling to test the east, west and central down-dip extensions; b) Quebradillas Underground (3,000 m of drilling to test the strike and down-dip extensions of three key zones including Cuerpo 460, Norte-Sur, and San Nicolas; and c) San Marcos (1,000 m of drilling to test the extension of San Marcos and Cuerpo 1100 at depth.
- Tocvan Ventures Corp., provided an update on the acquisition of the Pilar project in Sonora and outlined target areas for the next phase of drilling. The company has exercised notice to Colibri Resources Corp., to purchase the remaining 49%. It also is completing a due diligence expected to finalize in coming weeks to acquire over 21 square-kilometers of land surrounding the Pilar, which contain recent placer activity, historic workings, and prospective geology, indicative that the area is highly prospective for gold and silver. “Tocvan plans to restart field operations at the close of the expansion acquisition to advance new target areas already identified quickly towards drill targeting. Drilling at Pilar and within the new expansion area is planned to total 2,000-meters before year end”.
- Silver Valley Metals provided a corporate update on its MexiCan lithium-potassium projects located in Zacatecas-San Luis Potosi. Highlights of this project include that significant grades of lithium, potassium sulphate, and boron are located on surface in unconsolidated sediments; the brine potential has not been tested to date; deep basin large aquifer brine potential defined by regional geophysics surveys, remains to be tested; he inferred resource has been tested from surface to an average 5 metres depth; the company anticipates the sediment basin could range from 40m to greater than 100m deep, so the prospect of expanding the sediment resource at depth is substantial; and 12.3M tonnes of Potassium Sulphate and 243K tonnes of Lithium Carbonate Equivalent defined thus far. The company declared that discussions are active and advancing with LitioMX and near-term plans are in place to come together to potentially finalize a partnership agreement.
