(TSXV: AGAG) (OTCQX: AGAGF) (FSE: T1K) ("Argenta" or the "Company") is pleased to report 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 (1). See Figure 1, Figure 2, Table 1, and Table 2. Notably, 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 (see press release dated February 23, 2026). Furthermore, 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 and underscore the vast, district-scale potential of the El Quevar Project.Highlights*:High-Grade Intercept at Mani-Copan:Hole QVD-444: Intersected 1,385 g/t Ag over 4.0m (from 271.0m to 275.0m). This high-grade interval confirms the continuity of mineralization at the Mani-Copan target, and the results are consistent with surface values obtained at the target, as announced in previous press releases. This validates the potential of Mani-Copan to host high-grade mineralization.New Discovery at Argentina Target: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.Exploration Upside at Andrea Target: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.Joaquin Marias, President, Chief Executive Officer, and Director of Argenta Silver Corp., commented:"These results reinforce the emerging district-scale potential at El Quevar. The high-grade intercept at Mani-Copan confirms meaningful silver mineralization beyond the current resource envelope, while consistent high-grade results at the Argentina target further expand the footprint of the system. Importantly, Mani-Copan and the Yaxtché deposit share a comparable geochemical signature; however, Mani-
