TSX-V: AGAG

VANCOUVER, BC, Oct. 26, 2026 /CNW/ -- Argenta Silver Corp. (TSXV: AGAG) (OTCQX: AGAGF) (FSE: T1K) ("Argenta" or the "Company") is pleased to announce additional shallow, high-grade silver drill results from the Mani target ("Mani") at its 100%-owned El Quevar Project in Salta Province, Argentina. Results from four newly reported diamond drill holes have confirmed silver mineralization extending from, or near surface, further supporting the potential for a second significant silver-mineralized system at El Quevar, separate from the existing Yaxtché Mineral Resource. Yaxtché hosts an NI 43-101 Mineral Resource Estimate of 45.3 Moz Ag Indicated (2.93 Mt at 482 g/t Ag) and 4.1 Moz Ag Inferred (0.31 Mt at 417 g/t Ag).

The latest drilling builds upon previously reported drill hole QVD-433, which contains several high-grade silver intervals including 4,982 g/t Ag over 7.50 meters (see news release dated February 23, 2026) all within a re-interpreted interval of continuous mineralization from surface of 56 m grading 710 g/t Ag. The new results combined with advanced geological interpretation supports Mani's emergence as a high-priority exploration target. The mineralization displays geological and geochemical characteristics consistent with those of the main Yaxtché Deposit, approximately 800 meters to the north.

In response to these encouraging results, Argenta has mobilized a third diamond drill rig to El Quevar, dedicated to advancing the Mani discovery. The Company is preparing a systematic 20-hole shallow drilling program to further delineate the mineralized footprint, while planning additional deeper drilling to investigate the potential connection between Mani and Copan.

Drill Highlights and Summary^*

Mani Target – Broad, Consistent High-Grade Silver Near-Surface Mineralization

• QVD-481: Intersected 67 g/t Ag over 38.5 m (from 1.5 m), including 111 g/t Ag over 13.50 m.
• QVD-482: Intersected 249 g/t Ag over 22.0 m (from 2.0 m) including 349 g/t Ag over 13.0 m. The hole ended in mineralization.
• QVD-483: Intersected 67 g/t Ag over 35.0 m (from 3.0 m), including 128 g/t Ag over 3.0 m and 137 g/t Ag over 6.0 m.
• QVD-484: Intersected 105 g/t Ag over 17.5 m from surface (0.0 m) including 143 g/t Ag over 6.0 m.
• Geological Similarities to Yaxtché: Mineralization at Mani exhibits geological and geochemical characteristics consistent with those observed at the Yaxtché Deposit.
• Accelerated Exploration: A third drill rig has been mobilized to systematically test Mani's near-surface mineralization through an initial 20-hole drilling program, while the Company's two existing rigs continue resource expansion drilling at Yaxtché.

Joaquín Marias, President, Chief Executive Officer and Director of Argenta Silver Corp., commented, "The discovery of high-grade silver mineralization right at surface, just a few hundred meters from our main Yaxtché Deposit, represents an exciting opportunity for El Quevar. The potential to delineate significant silver mineralization at shallow depths, in close proximity to our existing resource, could be potentially a gamechanger for the future development of the project. We are moving aggressively to test this opportunity with a dedicated third drill rig, while continuing to expand our high-grade silver resource at Yaxtché."

Mani Target Surface Exploration and Shallow Drilling Results

The Mani target is located approximately 700 to 800 meters south of the Yaxtché Deposit, within the Quevar South exploration area. Exploration in 2025 identified extensive high-grade silver mineralization in outcrop, with rock-chip samples returning values of 2,450 g/t Ag, 6,004 g/t Ag and 16,145 g/t Ag, among others, including results reaching the laboratory's upper analytical reporting limit of 20,000 g/t Ag (see news release dated July 21, 2025, and Figure 1).

These results outlined a high-grade silver-mineralized footprint measuring approximately 500 m by 90 m along the Mani target.

Following the identification of this prospective footprint, the Company's exploration team completed a systematic surface sampling grid with a spacing of approximately 15 m by 15 m, designed to better characterize the distribution and continuity of silver mineralization across the exposed area (Figure 2).

Encouraging results from this detailed sampling program led to an initial campaign of six shallow diamond drill holes, designed to test the near-surface mineralization and provide geological information for subsequent exploration.

The four newly reported holes, QVD-481 through QVD-484, all intersected silver mineralization from or near surface, with individual hole depths not exceeding 50 meters (Figure 3). These results strengthen Mani's position as a high-priority, near-surface silver exploration target at El Quevar.

Notably, QVD-482 intersected 249 g/t Ag over 22 m from surface (2.0 m), including 349 g/t Ag over 13.0 m from 10.0 m, which contains a higher-grade interval of 473 g/t Ag over 4.0 m. The hole was terminated while still in mineralization due to operational difficulties.

Additional results include 105 g/t Ag over 17.5 m from surface (0.0 m) including 143 g/t Ag over 6.0 m in QVD-484; 67 g/t Ag over 38.5 m from 1.5 m, including 111 g/t Ag over 13.50 m, which includes 326.0 g/t Ag over 2.0 m in QVD-481; and 67 g/t Ag over 35.0 m from 3.0 m in QVD-483.

The latest results complement previously reported Mani discovery holes QVD-419, which intersected 45 g/t Ag over 15.0 m from 17.0 m, and QVD-420, which returned 121 g/t Ag over 4.0 m from 41.0 m, including 204 g/t Ag over 2.0 m (see news release dated October 27, 2025).

Subsequent drilling further highlighted the potential of the target through QVD-433, which returned 710 g/t Ag over 56.0 m from surface (0.0 m), including an exceptional high-grade interval of 4,982 g/t Ag over 7.5 m from 39.5 m (see news release dated February 23, 2026).

Together, these results provide additional evidence of significant near-surface silver mineralization across the Mani target and support further drilling to assess its lateral and vertical continuity.

Mani–Copan Multiple Mineralized Levels and Exploration Potential

Exploration completed to date has identified three principal levels of silver mineralization along the Mani–Copan trend, providing an important geological framework for future drilling (Figure 4).

Surface level: Surface to approximately 25 m depth

Near-surface silver mineralization has been intersected in multiple drill holes, including QVD-482, QVD-484 and QVD-433, providing further confirmation of high-grade silver mineralization within the upper portion of the Mani target.

Near Surface level: Approximately 30 to 45 m depth

Some of the highest silver grades encountered at Mani occur at intermediate depths. These include 326.0 g/t Ag over 2.0 m from 37.0 m in QVD-481, and the exceptional 4,982.0 g/t Ag over 7.5 m from 39.5 m in QVD-433.

These intercepts highlight the potential for high-grade silver mineralization below the exposed surface footprint, with additional drilling required to determine its geometry and continuity.

Deeper level: Approximately 270 m depth

East of the shallow Mani mineralization, drilling at Copan has identified an additional, deeper silver-mineralized zone.

Hole QVD-444 intersected 1,385 g/t Ag and 0.87% Cu over 4.0 m from 271.0 m (see news release April 28, 2026).

The spatial distribution of these mineralized intercepts suggests the potential for a broader, structurally controlled silver-mineralized system extending from Mani toward Copan. However, the geological connection and continuity between the shallow and deeper zones have not yet been established and remain key objectives of the Company's ongoing exploration program.

Importantly, the style of mineralization and geochemical signature observed at Mani–Copan are similar to those of the main Yaxtché Deposit, which hosts an Indicated Mineral Resource of 45.3 million ounces of silver contained in 2.93 million tonnes grading 482 g/t Ag, and an Inferred Mineral Resource of 4.1 million ounces of silver contained in 0.31 million tonnes grading 417 g/t Ag.

These similarities support the Company's interpretation that Mani–Copan may represent an additional silver-mineralized system within the broader El Quevar district. The mineralization at Mani–Copan is separate from the current Yaxtché Mineral Resource and has not been included in the existing Mineral Resource Estimate.

Third Drill Rig Mobilized to Accelerate Mani Exploration

Following the encouraging results from surface sampling and the initial shallow drilling program, Argenta has mobilized a third diamond drill rig to El Quevar, dedicated to advancing the Mani target (Figure 5).

The Company's two existing drill rigs will continue focusing on resource expansion drilling at Yaxtché, while the additional rig will undertake an initial 20-hole shallow diamond drilling program at Mani.

The program is designed to systematically test the lateral and vertical extent of near-surface silver mineralization, improve the understanding of its geometry, and investigate potential extensions beyond the currently defined mineralized footprint.

In parallel, the Company's technical team is planning a series of deeper drill holes to evaluate the potential structural relationship between the shallow Mani mineralization and the deeper high-grade intercepts at Copan. This work is expected to form part of the upcoming Argentine summer exploration campaign.

About El Quevar Project

The El Quevar Project is in Salta, Argentina and spans an area of 57,000 hectares. The property remains underexplored, with less than 3% of the area covered by 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 includes 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.
