Argenta Silver Corp. (TSX-V: AGAG) (OTCQB: AGAGF) (FSE: T1K) is pleased to report the first batch of assay results from its ongoing 2025 winter diamond drilling program at the 100% owned El Quevar Project in Salta Province, Argentina. The first drill holes completed by the Company on the El Quevar Project have delivered wide, high-grade silver intersections, and results from additional sampling of historic drill core confirms upside for resource expansion. Surface rock sampling from underexplored areas on the property have returned multiple high-grade silver results highlighting the growth potential of new mineralized zones.
Highlights
*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.
Joaquin Marias, CEO, President and Director of Argenta Silver Corp. commented: “The wait is over. While silver spot prices are on the verge of new record highs, our first batch of results is here, a true statement of El Quevar’s potential to deliver unparalleled results. Since the company’s inception, our approach has been laser–focused on creating sustainable value for our stakeholders. With assays returning 533 g/t Ag over 20.20 m in a drill intercept, a surface rock-chip sample topping 20,000 g/t Ag and legacy core that has been sampled for the first time returning positive high-grade silver results, we’ve only just begun to unlock the true potential of this high–grade silver system. Expect more results from the ongoing exploration program.”
2025 Winter Drilling Program Results – First Group of Results
Drilling kicked off in late May as part of a fully funded 4,000 m winter campaign designed to confirm known high–grade zones, step out along strike, and test new targets. Assays from the first three drill holes have been received, with results for the remaining holes expected by mid-August and mid-September.

*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.
The results from the three drill holes received to date as well as the surface rock sampling validate the Company’s existing resource model and underscore the untapped potential at El Quevar. They confirm the high-grade, pure silver character of the mineralization and reinforce the need of systematic exploration when less than 3% of the property has seen modern exploration.

2025 Surface Sampling Results – First 2025 Batch
Surface exploration work started on January 3, 2025 (see news release of January 6, 2025), leading Argenta to submit approximately 1,000 soil samples and over 400 rock chip samples for laboratory analysis. Rock sampling primarily targeted the “Mani”, “Andrea”, “Rosa”, and “Argentina” exploration areas. Soil samples were systematically collected using a grid pattern, with 200×200-meter and 100×100-meter spacing, and infill sampling at 50×50 meters to ensure comprehensive coverage of the Quevar South central zone.
With numerous rock chip surface assays still pending from the laboratory, initial results already reveal multiple high–grade silver values. More than twenty rock chip samples returned grades above 150 g/t Ag, including several exceeding 1,000 g/t Ag. Notably:
Although these high values do not reflect the deposit’s average grade, they clearly demonstrate the strong potential of the El Quevar mineral system.
Meanwhile, analytical results from the soil sample grid have revealed new areas with anomalous silver values, including soil samples reaching 147 g/t Ag and 296 g/t Ag.
By integrating these results with historical data from previous operators, Argenta has identified multiple new areas with highly anomalous values in silver and pathfinder elements that will guide our technical team to define future drill targets.
The findings from the expanded surface soil geochemistry program indicate the potential of a significantly larger mineralized system at El Quevar beyond the current resource. The well-defined silver zone demonstrates strong continuity, while newly identified gold anomalies reveal promising new exploration targets that were historically underexplored. Importantly, these zones have seen minimal drilling, representing substantial untested exploration potential.
Historical Drill Core Sampling Results and Phase 1 Results
Phase 1 of the 2025 Exploration Program at El Quevar (see news release from May 14, 2025) represented Argenta’s first systematic evaluation of the project, targeting altered and mineralized structures with anomalous geochemical, spectral and geophysical signatures. The principal aim in the Quevar South area was to refine the geological model by reinterpreting and remodeling existing historical data, and then backing it up with new, systematically collected surface samples, detailed structural mapping and re-logging and validation of legacy core logs. These efforts have confirmed the strong potential for additional high–grade silver and gold mineralization in untested targets beyond the Yaxtché deposit.
A key opportunity lies in the fact that only about 35 % of historical drilling (~ 38,000 m) has been cut and assayed, leaving some 66,000 m of core unanalyzed and available at a low cost for potential resource expansion. To kick–start this, Argenta sampled a portion of the unanalyzed Yaxtché drill holes (25 holes in total) and returned significant silver mineralization in five holes, with a standout intercept of 882 g/t Ag over 1.00 m and an average grade of roughly 226 g/t Ag across those samples.
Particularly elevated silver grades were identified in the following drillholes:
*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.
About El Quevar Project
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 (1). The mineral resource area remains open at depth and in multiple directions, particularly to the southeast and northwest. One of the objectives of the 2025 Winter Drilling Program is to specifically target and expand these high-grade Yaxtché zones.
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.
QAQC Statement
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 diamond-sawn on-site, and half drill-core samples were securely transported to Alex Stewart Laboratories’ (ASI) sample preparation facilities in Jujuy, and forwarded to their facility in Mendoza, Argentina for analysis. The other half-core is retained on site for reference.
Soil samples were prepared by drying and sieving to minus 80 mesh. Rock chip and diamond drill core samples were dried and then underwent 2 stage crushing to 80% passing minus 10 mesh before collecting a 600 gram split that was pulverized to 90% passing -140 mesh. A 200 gram split is sent for analysis and the remaining 400g is archived. All samples were analyzed for gold using a fire assay on a 50-gram sample with an AAS finish, and for 39 elements by 4 acid, ICP-OES on a 0.2-gram sample. Soils were also analyzed for mercury using cold vapor AA on a 0.2-gram. Overlimit silver was determined by a 50-gram fire assay with a gravimetric finish and over limit lead, zinc and copper were determined by ICP_OES using a mixture of highly oxidizing acids on a 0.2-gram sample.
