ON MEXICO ISSUES

  • Pan American Silver Corp, Coeur Mining Inc, Luca Mining Corp, GoGold Resources Inc, and Axo Copper Corp., reported the best drilling intercepts in Mexico on the second week of September, 2025. Details are shown in the table below:

ON EXPLORATION

  • Questcorp Mining Inc., provided an update on the Phase 1 ongoing drilling program at its la Union project in Sonora. The company has completed drill holes at two of four target areas with promising intersections in oxides zones associated with past mineralization. The drilling has revealed more quartzite than expected which could indicate good conditions for gold due to fractures and oxidation. Questcorp is now focusing its drilling exploration efforts at the Famosa target.
  • Fortuna Mining Corp., provided an update on its generative exploration program across its portfolio of properties in Mexico. At the Centauro project in Chihuahua, the company conducted geological mapping, geochemical sampling, and the identification of a large 2km by 3km silica-capped with features typical of a preserved hydrothermal system, such as sinter horizons, silica banding, mud cracks and geyserites. Several north-west trending silicified structures have been outlined, and along with the low temperature sulfides such as realgar, orpiment, cinnabar, and stibnite, confirm the presence of structures consistent with a fertile epithermal system. The plan moving forward is to commence a first pass drill campaign next month to test the potential for a low to intermediate epithermal sulfidation gold and silver system at depth, aiming to explore and delineate mineralization within the identified structures. Fortuna has the option to earn 100% interest in three mining concessions covering 600 hectares. At El Carmen project in Queretaro, activities realized to date include initial mapping on a large 5km by 5km kaolin-altered area locally exposed beneath a post-mineral basalt cover, which has identified three main target areas characterized by well-developed displacement faults, sub horizontal zones of silicification, and the presence of cinnabar, all indicative of the potential for a fully preserved epithermal system at depth. Once the company secured surface access over the principal target areas, it will commence detailed geological mapping and systematic geochemical sampling, supported by hyperspectral analysis to better understand its mineralization potential to design a maiden drill program.
  • Chesapeake Gold Corp., provided an update on its regional exploration activities at its Lucy project in Sinaloa. Recent work has identified new mineralized zones, including a potential new corridor with gold mineralization. The project shows promise for extending over 3 kilometers, suggesting that the mineralization system at Lucy is bigger than it was originally thought. Ongoing trenching, sampling, and permitting activities are been carried out at the property with the goal of delineating its mineral potential.
  • Pacifica Silver Corp., revealed details of its upcoming exploration program at its Claudia project in Durango. The company plans to drill an initial 8,000m Phase 1 drill campaign, expected to begin at the end of September, and conduct a property-wide exploration program consisting of surface sampling, geological mapping, and a 27-line km induce polarization (IP) and resistivity geophysical survey.
  • Pinnacle Silver and Gold Corp., released underground channel sampling results from the Dos de Mayo mine within its Potrero project in Durango. “Fifty-three channel samples, in 13 composite channels, were taken within a raise (inclined tunnel approximately 1.5m in diameter) connecting two levels 25.5m apart.  Composite assays up to 11.2 g/t Au and 179 g/t Ag over 3.5m, 15.55 g/t Au and 222 g/t Ag over 1.1m and 11.93 g/t Au and 190 g/t Ag over 1.4m were obtained, with individual assays up to 27.6 g/t Au and 366 g/t Ag over 0.6m.  The weighted average of mineralized composites within the raise assayed 6.43 g/t Au and 110 g/t Ag”.  The company is planning an underground drilling program in all three main mines at Potrero project.
  • Defiance Silver Corp., reported that a new 10,000m oriented-core drilling program commenced at its Zacatecas project in Zacatecas state.
  • Axo Copper Corp., released results from its recently initiated phase II drill program at its la Huerta project in Jalisco. The most significant drill interception was encountered in hole LHCC-25-045 with 2.89% Cu and 15 g/t Ag (3.08% CuEq) over a length of 13.2m, including 4.86% Cu and 30 g/t Ag (5.24% CuEq) for a length of 6.4m. Mineralization encountered in this hole consists of chalcopyrite and bornite hosted in andesitic rocks. Higher Cu grades are related to bornite patches. To date, 3,288m have been drilled as part of a 15,000m phase II drilling program. Axo also announced that it has begun its regional drill program at the La Huerta South target.

  • Vizsla Royalties Corp., spotlighted that Vizsla Silver Corp., entered in a USD $220M project finance mandate with Macquarie Bank Limited to fund the construction and development of its high grade underground Panuco project in Sinaloa.
  • Sonoro Gold Corp., closed its previously announced oversubscribed, non-brokered private placement of 13,350,000 units at a price of CAD $0.15 per unit for gross proceeds of CAD $2M. Net proceeds will be used to fund the ongoing development of its Cerro Caliche project in Sonora, and for general working capital purposes.
  • Goldgroup Mining Inc., closed its previously announced non-brokered private placement of 4,848,485 units at a price of CAD $0.825 per unit for gross proceeds of CAD $$M. The gross proceeds will be dedicated to the diligent assessment and strategic pursuit of acquisition opportunities (Cerro Prieto mine, Sonora).
  • Vortex Metals Inc., announced a non-brokered private placement of up to 15,000,000 units at a price of CAD $0.04 per unit for gross proceeds of up to CAD $600K. Net proceeds will be used as follow: approximately 40% to pay for mining concession fees, approximately 40% to pay for exploration fees and remaining 20% for general working capital purposes (Riqueza Marina and Zaachila projects, Oaxaca).

ON RESOURCES AND DEVELOPMENT

  • Kootenay Silver Inc., reported that it drilled five holes at its Columba project in Chihuahua. These holes totalling 2,500m were completed on the D and I Vein Targets, and are part of the first phase of a planned 50,000m drilling program designed to expand known limits of mineralized veins comprising the recently announced 43-101 compliant mineral resource estimate.
  • Luca Mining Corp., released results from its ongoing underground and surface drilling programs of its Tahuehueto mine in Durango. Six holes are already been completed for a total of 1,656m. Drilling highlights are shown in the table below:
  • Sierra Madre Gold and Silver Ltd., announced its two-staged plan to expand their Guitarra mine´s processing capacity from 500 tonnes to between 750 and 800 tonnes per day by mid-2026 through new facilities such as a paste fill plant and thickener plant, as well as additional crushers; and then between 1,200 and 1,500 per day by late 2027 with a new dry stack tailings storage facility, a second crushing circuits, and replacing a smaller capacity ball mill.   The company intends to fund these expansions using their existing cash flow and recent private placement, avoiding new capital raises.
  • Chesapeake Gold Corp., reported progressing metallurgical test on its Metates project in Durango, with promising results toward a 2026 prefeasibility study. Metallurgical testwork on Metates using its proprietary sulphide leach technology shows early encouraging results, indicating that the oxidation process is meeting expectations, attracting industry interest. Now, other companies have considered to test the Chesapeake´s leach process technology on a wide range of deposits, which could open up new chances for the company to start commercializing the process as an eventual significant source of value generation for Chesapeake.
  • GoGold Resources Inc., announced strong drilling results at its Los Ricos South project in Jalisco. Based on reconstruction of the historical data and a new IP geophysics survey conducted this year, a systematic step-out drilling program commenced in January 2025, to test the down dip, the southern strike extension of the Abra Zone towards Los lamas, and the Cerro Colorado deposit. The company found high-grade silver and gold mineralization beyond their current resource area, notably in the Eagle, Abra, and Cerro Colorado zones. Highlights include impressive silver equivalent grades over notable widths, signaling potential for resource expansion and deeper extensions of known veins. Drilling highlights are shown in the table below:

Pan American Silver Corp., released drill results from the program designed to test the eastern zone of the La Colorada mine in Zacatecas. These results are from the drilling campaign carried out from November 2024 to June 2025 with approximately 65,000m in 170 holes. Multiple high grades were encountered indicating the potential for expansion of silver mineral resources, extension of mine life and improved economics. These results are  Drilling highlights are shown in the table below:

Coeur Mining Inc., released drill results from its 2025 drill plan at its Las Chispas mine in Sonora. The 2025 drill plan was modified and refocused around the Las Chispas operation to test high-priority targets including strike and depth extensions and infill drilling at the Babicanora and Las Chispas Block. It also continues to follow up on recent discoveries in the Gap Zone located between the Babicanora and Las Chispas Blocks on multiple veins such as Augusta, La Sorpresa, Los Sheiks, North Las Chispas, and Las Chispas Extensions. The drilling results have been highly successful, revealing some of the highest grades encountered in the project to date. Notably, North Las Chispas Vein returned an intercept of 158 g/t Au and 13,430 g/t Ag over 0.30m, bonanza levels with exceptional high-grade mineralization. The Augusta vein has also demonstrated significant expansion, with intercepts of up to 27.7g/t Au and 3,903 g/t Ag over 0.40m, confirming continued growth along strike. Overall, the results highlight substantial high-grade potential and ongoing resource expansion in multiple veins within the Las Chispas district, which have been ramped up to nine drill rigs to target additional resource growth.

Consolidated Zinc Limited (ASX:CZL) has discovered further high-grade zinc mineralisation 2.5km along strike from the Plomosas underground mine at its project in northern Mexico.
First pass rock chip sampling at the Alfonsitos prospect returned exciting results with grades up to 18.53% and 24.34% Zn+Pb from workings and 15.05% Zn+Pb from outcrop.
Alfonsitos is the first of several prospects identified by reconnaissance exploration and geophysical surveys previously reported to the ASX in November 2016.
“The ongoing regional exploration in proximity to the existing underground mine continues to reveal promising results,” Managing Director Will Dix said.
“The Alfonsitos area, located north west of the current Plomosas mine, has the same geological setting to the mine itself and displays a similar style of mineralisation at surface. This provides further encouragement that there is potential for significant new discoveries and additional resource tonnes at Alfonsitos and within the existing tenement portfolio.
