Argenta Announces Mobilization for 2025 Drilling Program at El Quevar Project and appoints Vanessa Bogaert as VP of Investor Relations and Communications

TSXV – AGAG

VANCOUVER, BC, May 26, 2025 /CNW/ - Argenta Silver Corp. (TSXV: AGAG) (OTCQB: AGAGF) (FSE: T1K) ("Argenta" or the "Company") is pleased to announce that mobilization has begun for the 2025 drilling program at the El Quevar Project in Salta Province, Argentina. Drilling operations are scheduled to begin within the next 10 days, following the successful completion of Phase 1 of the Company's 2025 exploration program, where significant progress was achieved.

The Phase 2 program will consist of approximately 4,000 meters of diamond drilling using a single rig, with activities concentrated in Quevar South. These areas are strategically located near, and are believed to be geologically related to, the Yaxtché deposit (the basis of the existing mineral resource estimate). Yaxtché currently hosts an Indicated Resource of 45.3 million ounces of silver at a grade of 482 g/t Ag, and an Inferred Resource of 4.1 million ounces of silver at a grade of 417 g/t Ag¹, ranking it among the top undeveloped silver deposits in Argentina.

Originally explored extensively between 2008 and 2013 by its previous owner, the project has since seen only limited and sporadic exploration activities. Of the 104,000 meters of historical drilling conducted by previous operators, over 75,000 meters were drilled within the current Mineral Resource Estimate area, reducing the emphasis on the broader exploration upside.

The 2025 drilling campaign will consist of approximately 15% confirmation drilling, 25% step-out and resource expansion drilling, and 60% exploration drilling on  new targets identified during Phase 1. These exploration targets are located in areas that display similar structural and mineralogical features to the Yaxtché deposit, offering strong potential for new discoveries and for expanding the mineralized system.

Joaquín Marias, Chief Executive Officer of Argenta, commented: "As planned and on time with our schedule, this 4,000-meter winter drill program is about to commence, representing one of our first major steps forward since acquiring El Quevar. It's the beginning of a broader strategy to unlock the project's full potential, not just geologically, but economically. We're already envisioning a more expansive drill program during the Argentine summer. This campaign is about laying down the foundation, carefully and decisively, for what we believe can become one of the premier silver assets in Argentina."

Despite the challenges posed by winter conditions in the Argentine Andes, Argenta will proceed with this program using a single rig specially prepared for the El Quevar Project. The Company will be one of the few exploration companies actively drilling during this season, underscoring its deep commitment to advancing the El Quevar Project and creating value for shareholders.
