Argenta Silver Corp. Intersects 246 g/t Ag over 20.00m and Discovers New Gold-Copper Target at El Quevar Project and Adoption of RSU/PSU/DSU Plan

Highlights:

• QVD-423: the first hole of the 2025–2026 Summer Campaign, intersected 246 g/t Ag over 20.00m, including a high-grade intercept of 427 g/t Ag over 6.00m and a standout 1,075 g/t Ag over 1.00m. This intercept successfully tested a 100-meter gap previously devoid of drilling, confirming mineralization continuity with grades consistent with adjacent areas. *
  
  
• QVD-424: Although prematurely terminated at 353 meters due to operational challenges, the drillhole intersected 160 g/t Ag and 1.35% Cu over 1.00m (from 300 to 301m), followed by 0.35 g/t Au and 0.76% Cu over 1.00m at the bottom of the hole. These intercepts are highly significant as the hole ended in mineralization, suggesting that the system extends well beyond current depth models. This provides compelling justification to re-enter or twin the hole to reach the intended primary target. *
  
  
• QVD-425 (Carmen Discovery): The inaugural drillhole into the Carmen exploration target confirmed a new discovery located 350m northeast of the Yaxtché Deposit. The hole intersected a broad mineralized interval of 44.00m grading 0.57 g/t Au and 0.58% Cu (from 316m), which includes several high-grade zones: 2.56 g/t Au and 4.33% Cu over 2.00m, and two standout copper intercepts of 3.92 g/t Au with 6.23% Cu over 1.00m, and 4.87 g/t Au with 8.52% Cu over 0.80m. This discovery could potentially identify a separate gold-copper system that remains open in multiple directions. *

Joaquin Marias, CEO, President and Director of Argenta Silver Corp. commented: "These first results from the 2025–2026 Summer Drill Program confirm both the strength and continuity of high-grade silver mineralization at Yaxtché and the broader geological potential of the El Quevar district. Intersecting 246 g/t Ag over 20 meters in a previously undrilled gap reinforces the robustness of the existing resource model, while the discovery of a new gold-copper system at the Carmen target highlights the scale and multi-commodity upside of the project. With the program focused on both resource growth and new discoveries, these results validate our exploration strategy and provide a strong technical foundation for continued drilling and systematic expansion of the mineralized footprint at El Quevar."

2025–2026 Summer Drilling Program Results – Initial Assays

The 2025–2026 Summer Drilling Program, encompassing ~15,000 metres of diamond drilling, is currently in full swing following its commencement on 1 November 2025 (see press release November 13, 2025). With two drill rigs fully operational across the El Quevar Project, the Company is executing a balanced growth strategy: 40% of the program is dedicated to Resource Expansion to solidify the existing asset base, while 60% is focused on New Discoveries, targeting high-impact exploration horizons.

Since November, the Company has successfully completed over 6,500 metres of drilling, with more than 130 work orders submitted for laboratory analysis. Unfortunately, due to the increase in precious metal prices, laboratories have been encountered with massive amounts of samples from multiple companies, delaying results. Complementing the drill program, the 2025–2026 Summer Campaign incorporates an extensive suite of technical studies designed to refine the geological model for the Yaxtché Deposit and emerging targets. This includes comprehensive mapping, soil and rock sampling, and geophysical surveys, alongside specialised petrographic and structural analyses to de-risk and accelerate the project's development.

Key Drill Hole Highlights:

• QVD-423 (Yaxtché Continuity): The first hole of the campaign successfully tested a 100-meter gap, intersecting 246 g/t Ag over 20.00m, including a high-grade core of 427 g/t Ag over 6.00m and a standout 1,075 g/t Ag over 1.00m.
  
  
• QVD-424 (Target Extension): Although terminated prematurely at 353 metres due to operational challenges, the hole ended in mineralization, grading 0.35 g/t Au and 0.76% Cu over 1 meter at the bottom. This confirms the system remains open and provides compelling justification for follow-up drilling to reach the primary target depth.
  
  
• QVD-425 (Carmen Discovery): As the inaugural drillhole into the Carmen exploration target, results have confirmed a major new discovery 350m northeast of Yaxtché. The hole intersected a broad interval of 44.00m grading 0.57 g/t Au and 0.58% Cu, highlighted by a high-grade copper intercept of 6.23% Cu and 3.92 g/t Au over 1.00m.

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.

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 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. Overlimit silver was determined by a 50-gram fire assay with a gravimetric finish and overlimit lead, zinc and copper were determined by OG62 using a mixture of highly oxidizing acids on a 0.4-gram sample.
