ON MEXICO ISSUES
- The full Supreme Court of Justice of the Nation (SCJN) revoked an injunction granted to a private individual against the reforms to the Mining Law regarding mining and water concessions promoted by former President Andrés Manuel López Obrador (AMLO). By seven votes in favor and two against, the justices denied the judicial protection requested by the individual because the new concession applications that were in process were dismissed without further proceedings after the reforms came into force in May 2023. During the debate, Hugo Aguilar, president of the SCJN, affirmed that the sovereignty of the State must prevail at all times and that under no circumstances does anyone who submits a mining concession application already have an acquired right, simply by submitting it. (Editor´s Note: The SCJN´s decision is a bad sign, not only for the mining industry but for the entire country, because no respect for the non-retroactivity of laws has been demonstrated, and that’s a basic principle for the Rule of Law).
- GR Silver Mining Ltd., and Kingsmen Resources Inc., reported the best drilling intercepts in Mexico on the fourth week of September, 2025. Details are shown in the table below:

ON EXPLORATION
- Riverside Resources Inc., and Questcorp Mining Inc., informed that are conducting a drilling program at the Union project in Sonora, targeting five mineral zones. Currently, three targets are actively being drilled, focusing on historic mining areas and new potential zones like Famosa, which shows signs of gold mineralization. The program is progressing on schedule and budget, with promising signs of gold-bearing mineralization, especially in areas with significant quartzite and structural features. The first hole was drilled southeast beneath historic workings, and two more holes were drilled at the El Cobre mine area and the North Union Mine area, perpendicular to stratigraphy and toward interpreted feeder zones along pre-mineral fault structures, primarily within the Clemente Formation. Core samples have been sent to the lab and assays are pending. Goal of this exploration campaign is to define mineralization controls, refine exploration models, conduct an additional induced polarization (IP) survey and evaluate sulfide zones, with ongoing geological interpretation and assay results guiding their next steps.
- Colibri Resources Corporation reported that it has engaged TerraEye to advance and enhance exploration at the EP Gold Project in Sonora using a mix of multispectral satellite imagery, geospatial data, AI and data integration like magnetics, gravity, and geochemical database to uncover promising gold targets even hidden by dense vegetation. The goal is to produce a ranked list of exploration targets with detailed maps and reports to accelerate discovery, reduce exploration risks, and optimize field work and drilling efforts, with a planned program in 2025 to expand target identification beyond the initial three drill-tested zones.
- Kingsmen Resources Inc., announced initial results from its Las Coloradas project in Chihuahua. Hole LC-25-010 intersected 1,028 g/t AgEq over 1.45m (455 g/t Ag approx), including 1,742g/t Ag over 0.7m (770 g/t Ag approx) and a broader zone of 138 g/t AgEq over 13.35m, confirming potential for high-grade, shallow mineralization near historic ASARCO mining areas. The mineralization includes massive sulfides with sphalerite, galena, arsenopyrite, and pyrrhotite, and shows strong pathfinder elements like antimony, bismuth, and indium, indicating a large, underexplored system. The project covers a historic district with multiple untested structures, and only a small part has been explored. Kingsmen plans to analyze additional drill holes and continues to assess the district’s extensive mineral potential. The company emphasizes the significance of these results in confirming the presence of high-grade silver mineralization and the potential for further discoveries in this prolific mining district.
- Pinnacle Silver and Gold Corp., discovered a new vein called El Capulin at its Potrero project in Durango that along with the surface sampling conducted above the Pinos Cuates and Dos de Mayo mines reinforces the idea that a robust low-sulphidation epithermal vein system with significant gold-silver mineralization has been identified at the property. Surface sampling has extended the high-grade-gold and silver mineralization over a vertical distance of up to 80m above the Los Cuates and Dos de Mayo mines, with grades of up to 2,280 g/t Ag and 1,444 g/t Ag, suggesting vertical zonation with silver increasing upwards. Also, sampling on the newly discovered El Capulin vein, with a strike length of 375m, returned values up to 6.27 g/t Au and 99 g/t Ag. This vein lies parallel to Dos de Mayo, 200m away. In addition, mapping at the La Dura mine could extend the Dos de Mayo vein strike length to 500m, with the vein traced for 1,600m overall. All these results add a lot of potential to the El Potrero property.
ON MINING
- Guanajuato Silver Company Ltd., made significant upgrades to its mining fleet at its El Cubo and Valenciana mines in Guanajuato, including the delivery of three new low-profile trucks, three scooptrams, and three ordered “Torino” haulage trucks to arrive later. These modern vehicles are designed for enhanced safety, stability, and efficiency underground, aiming to improve operational reliability, increase production, and optimize fleet utilization. The company emphasized that these investments are critical to supporting long-term growth and operational success.
ON FINANCING
- Masivo Silver Corp., increased its previously announced non-brokered private placement due to strong investor demand from 16,666,667 to 33,333,334 units for gross proceeds from CAD $1M to CAD $2M. The offering will be priced at CAD $0.06 per unit (Cerro Colorado project, Sonora).
- Silver Storm Mining Ltd., closed its previously announced bought deal private placement of 55,065,000 units at a price of CAD $0.25 for gross proceeds of CAD $13,766,250. The company plans to use the net proceeds to advance the restart of the La Parrilla mine in Durango, as well as for general corporate purposes and working capital.
- Sandstorm Gold Royalties announced that proxy advisory firms recommended Sandstorm shareholders vote in favor of the proposed arrangement with Royal Gold Inc, scheduled for October 9, 2025. Under the deal, Sandstorm shareholders will receive 0.0625 shares of Royal Gold for each Sandstorm share. The Board of Directors of Sandstorm unanimously supports the vote for the arrangement resolution.
- Aztec Minerals Corp., announced a bought deal private placement offering of 21,300,000 common shares of the company at a price of CAD $0.235 per offered share for gross proceeds of CAD $5M, but later on it announce an upsize of the bought deal to 37,020,000 common shares at a price of CAD $0.235 for gross proceeds of CAD $8,699,700. Part of the gross proceeds will be used to conduct exploration work at the Cervantes project in Sonora, as well as for general working capital purposes.
- Zacatecas Silver Corp., closed the first tranche of its previously announced private placement for gross proceeds of CAD $2,306,960 by issuing a total of 38,449,335 units at a price of CAD $0.06 per unit. The company plans to use the net proceeds to fund a drilling campaign on its Zacatecas Silver project in Zacatecas.
- Oroco Resource Corp., announced a non-brokered private placement of up to 18,000,000 units at a price of USD $0.20 for gross proceeds of up to USD $3.6M. Oroco will use the net proceeds for the advancement of its Santo Tomas project in Sinaloa, as well as for working capital and other general corporate purposes.
- Questcorp Mining Inc., informed that it will offer up to 17,500,000 units at a price of CAD $0.20 per unit in a non-brokered private placement for gross proceeds of up to CAD $3.5M. The company plans to use part of the gross proceeds for advancement of ongoing exploration and drill work at the La Union Gold and Silver Project in Sonora, and for general working capital purposes.
- Kenadyr Metals Corp., closed the second tranche of its previously announced non-brokered private placement of 1,959,665 subscription receipts of Kenadyr at a price of CAD $0.37 per subscription receipt for gross proceeds of CAD $734,874.38. In addition to the first tranche closing proceeds of CAD $2,281,513.75, the Offering has raised CAD $3,800,000. The company will used the proceeds to fund payment obligations and exploration expenditures relating to the Adelita Project in Sonora, and for general working capital purposes.
ON RESOURCES AND DEVELOPMENT
- Guanajuato Silver Company Ltd., made significant upgrades to its mining fleet at its El Cubo and Valenciana mines in Guanajuato, including the delivery of three new low-profile trucks, three scooptrams, and three ordered “Torino” haulage trucks to arrive later. These modern vehicles are designed for enhanced safety, stability, and efficiency underground, aiming to improve operational reliability, increase production, and optimize fleet utilization. The company emphasized that these investments are critical to supporting long-term growth and operational success.
- GR Silver Mining Ltd., released drilling results from the San Marcial area at its Plomosas project in Sinaloa. Drill hole SMS25-10A intersected two distinct mineralized zones in the Parallel Breccia Target, including374 g/t Ag over 9m with high-grade intervals of 1,542 g/t Ag, 1.4% Cu, and 0.62% W over 1m, and 1.44 g/t Au over 33m, with a high-grade interval of 32.1 g/t Au over 1.2m. This drill hole is the farthest southeast drilled in the Parallel Breccia Target, confirming continuity of the mineralized structure over at least 500m from the Resource Area and supporting exploration models linking silver mineralization to a porphyry-style geological setting. The presence of high-grade Ag-Au zones, along with anomalous Cu and W grades, revealed intense high-temperature alteration minerals and epithermal-style quartz-calcite stockwork zones, suggesting proximity to a porphyry-related system and providing valuable vectoring tools for future exploration and strong potential for further resource expansion at San Marcial, particularly in the NE-SW structural trend.

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.

Mexico’s Best Drilling Intercepts, Second Week of October 2022
Gold, silver and copper, in these three elements drilling at the Dios Padre project in Sonora by Regency Silver topped the best intercepts of the week. The best intercept, 53.80 m @ 4.70 gpt Au, comes from an area 500 meters from the small silver resource already outlined, targeting a geophysical anomaly. The project is located on the Santa Rosa de Yecora mining district in Sonora, known mainly for the development of breccias in the contacts or near the contacts of an intrusive stock some 20 x 15 kilometers with ragged borders. Minera Alamos is currently mining the Santana project, Magna Gold has published in the last few years about its Mercedes project, Centerra drilled one more property in the district not long ago. The breccias can be rich in copper-molybdenum (Los Verdes), tungsten, gold (Santana), silver (Dios Padre, Guadalupe de Tayopa) or a combination of these elements. With the recent published intercepts by Regency Silver, more drilling is expected to come, and more attention to the district.
The intercepts from Panuco and Los Reyes in Sinaloa come from intermediate sulfidation epithermal mineralization in structures. The Avino mine results from Durango can be either categorizad as intermediate sulfidation epithermal in nature, or distal mineralization to a porphyry copper system, as recently suggested by Avino Silver on their press release.
