Argenta Silver Corp Reports the Fourth Set of Assay Results from Its Ongoing 2025–2026 Diamond Drilling Campaign At the El Quevar Project in Salta Province, Argentina
Argenta Silver Corp. reported the fourth set of assay results from its ongoing 2025–2026 diamond drilling campaign at the El Quevar Project in Salta Province, Argentina. The latest results highlight significant high-grade silver mineralization at the Mani-Copan and Argentina exploration targets, located 800 meters and 1,500 meters respectively, from the eastern edge of the current Mineral Resource, which hosts 45.3 million ounces of silver from 2.93 million tonnes grading 482 g/t Ag, and an inferred resource of 4.1 million ounces from 0.31 million tonnes grading 417 g/t Ag. Drill hole QVD-444 at Mani-Copan intercepted 1,385 g/t Ag over 4.0 meters, successfully validating high-grade results previously identified from surface samples. The Company has discovered a new, previously untested mineralized zone at the Argentina target, where all drill holes have encountered high-grade silver. These findings significantly expand the known mineralized footprint. Hole QVD-444 intersected 1,385 g/t Ag over 4.0m (from 271.0m to 275.0m). Hole QVD-448 returned multiple mineralized intervals, including a high-grade hit of 725 g/t Ag over 3.0m (from 78.0m to 81.0m). Hole QVD-450 demonstrated broad mineralization with 134 g/t Ag over 18.0m (from 181.0m to 199.0m), including higher-grade internal of 245 g/t Ag over 4.0m (from 189.0m to 193.0m). Intervals shown are core length. Estimated true widths vary between 60 to 85% of core reported length. Insufficient re-modelling and drill density on new data has been completed to calculate true width at this time. Drilling in the Andrea zone (Holes QVD-437 and QVD-441) returned anomalous silver values, confirming the presence of a mineralized system and providing key data for further targeting in this area. The Company continues to pursue a dual-track growth strategy: 40% of the Program targets Resource Expansion to strengthen the existing resource base, while the remaining 60% is focused on unlocking new discoveries beyond the existing footprint. To date, the Company has successfully completed over 14,500 meters across 61 holes, representing more than half of the total 25,000-meter program. Laboratory analysis is well underway; over 300 work orders have been submitted, with 40% of these results currently pending. This work supplements the 4,244 meters across 16 holes drilled during the successful 2025 Winter Drilling Program, which achieved a balance of high-grade Resource Expansion and the discovery of promising exploration targets such as Andrea, Rosa, Argentina, and Azufre. The discovery of a new mineralized zone at the Argentina target, situated more than 1.5 kilometers from the eastern edge of the current Mineral Resource, significantly expands the known mineralized footprint of the El Quevar Project. This emerging zone is headlined by high-grade intercepts of 725 g/t Ag over 3.0m and 134 g/t Ag over 18.0m. When coupled with results from the Mani-Copan target--located over 800 meters to the south of Yaxtché, where drilling returned an exceptional 1,385 g/t Ag over 4.0m--these findings underscore the vast, district-scale potential of the property. Furthermore, anomalous silver values identified at the Andrea target continue to provide the Company with critical geological vectors to refine future drilling across this expansive system. The El Quevar Project is located in Salta, Argentina and spans an area of 57,000 hectares. The property remains underexplored with less than 3% of the area covered with comprehensive exploration work. The property boasts exceptional infrastructure with over 60 km of internal roads, a fully owned, fully operational camp for 100 workers with multiple support buildings, and a railroad, gas pipeline, and service road just 3 km from camp, while a high-voltage transmission line lies approximately 20 km from the exploration area. The robust infrastructure associated with the project provides a cost-effective platform to de-risk and accelerate future drilling and development. The foundational Mineral Resource Estimate of the Yaxtché deposit boasts an indicated mineral resource of 45.3 million ounces of silver from 2.93 million tonnes grading 482 g/t Ag, and an inferred resource of 4.1 million ounces from 0.31 million tonnes grading 417 g/t Ag. The mineral resource area remains open at depth and in multiple directions, particularly to the southeast and northwest. The mineralization at the Yaxtché deposit is defined as a silver rich, high to intermediate-sulphidation epithermal system with associated gold. Mineralization is controlled by NW-SE and NE-SW fault structures and is mainly hosted in brecciated zones and dacite domes. Silver minerals at Yaxtché consist of complex silver sulphides, sulphosalts and native silver. These minerals are found within silicified breccias, commonly appearing as veinlets, stockworks, disseminations, and breccia fillings. The Company adheres to CIM Best Practices Guidelines for exploration-related activities conducted on its property. Quality Assurance and Quality Control (QA/QC) procedures are overseen by a Qualified Person. All geochemical sample assay results from Argenta Silver have been independently monitored through a rigorous QA/QC protocol. This protocol includes the regular insertion of blind standard reference materials, blanks, and duplicates. The logging and sampling of the El Quevar drill core were completed at Argenta's core handling facilities in Salta, Argentina. Drill core was photographed, checked for recovery and geotechnical and then diamond-sawn on-site, and half drill-core samples were securely transported to ALS Laboratories sample preparation facilities in Mendoza, and forwarded to their facility in Lima, Peru for analysis. The other half-core is retained on site for reference. Soil samples were prepared by drying at <60°C and sieving to minus 80 mesh (code PREP-41). Rock chip samples were dried and then fine crushing of the sample to at least 70% passing less than 2 mm, sample splitting using a riffle splitter, and pulverizing a 250 g split to at least 85% passing 75 microns (code PREP-31). Diamond drill core samples were dried and fine crushing of the sample to at least 70% passing less than 2 mm, sample splitting using a riffle splitter, and pulverizing a 1kg split to at least 85% passing 75 microns (code PREP-31B). All rock chip and diamond drill core samples were analyzed for gold using a fire assay on a 50-gram sample with an AAS finish, and for 35 elements by 4 acid, ICP-AES finish on a 0.75-gram sample plus mercury using cold vapor AA on a 0.2-gram (ME-ICP61m). Soils were also analyzed for gold fire assays and ICP-AES (Au-ICP21) and 48 multi-element four acid digestion with ICP-MS finish.
