Argenta Silver Validates Yaxtch Deposit Continuity

On October 27, 2025, Argenta Silver announced the fourth set of assay results from its 2025 Winter Diamond Drilling Program at the 100% owned El Quevar Project in Salta Province, Argentina.

Canada, 28th Oct 2025 - Global Stocks News - Sponsored content disseminated on behalf of Argenta Silver. On October 27, 2025, Argenta Silver (TSXV: AGAG) (OTCQB: AGAGF) (FSE: T1K) announced the fourth set of assay results from its 2025 Winter Diamond Drilling Program at the 100% owned El Quevar Project in Salta Province, Argentina.

The El Quevar project was purchased for USD 3.5 million in October 2024 after the previous operator sold numerous assets to resolve "urgent liquidity problems". It has a current market cap of CND $169 million.

Year-to-date, the price of silver has risen 62%, from USD $29/ounce to $47/ounce. Since the company started trading one year ago, Argenta's share price has risen 310% from .21 to .65.

The October 27, 2025 assay results confirm high-grade silver intervals within the Yaxtch? Deposit, notably including 694 g/t Silver over 2.1 meters. Additional drill results highlight 204 g/t Silver over 2.00 meters at the Mani exploration target. Results from the two remaining drillholes from the 2025 Winter Program are still pending from the laboratory.

"With summer conditions returning to Argentina and a strong treasury of C$23 million, Argenta Silver is fully funded and prepared to commence the 2025-2026 Drill Program at the El Quevar Project," stated Joaquin Marias, CEO, President and Director of Argenta Silver in the press release.

"This program marks the beginning of a new phase for the Company, building on the success of the prior exploration campaigns. Drilling at the Yaxtch? Deposit returned 35 meters grading 263 g/t Ag, confirming the continuity of high-grade silver mineralization in the deposit area."

"Results from our exploration drilling on new targets indicate the presence of a mineralized system nearby that we have integrated into our geological model and look forward to following up on in the upcoming drill program," added Marias.

Drilling began in late May as part of a 4,244-meter winter campaign designed with three objectives:

1. To confirm known high-grade zones2. To step out along strike

3. To test new targets

The first group of assay results were released on July 21, 2025, the second group were released on August 13, 2025, the third group of results were released on September 23, 2025.

The 2025 Winter Drilling Program concluded in the second week of September. Pending results from two exploration drillholes are expected by the beginning of November.

Confirmation drillhole QVD-411B proves the presence of multiple silver mineralization intervals that correlate with those encountered in historical drilling, as well as multiple gold mineralization intervals. The hole confirms the presence of a gold zone beneath the silver zone within the Yaxtch? Deposit.

Exploration drillhole QVD-418 returned anomalous silver results, which reinforce the presence of mineralization within the new exploration target, Atenea, located approximately 400 and 700 meters north of the Yaxtch? Deposit.

The exploration hole indicates that the mineralization extends towards the north of this new target and suggests the presence of an open new zone preserved beneath cover. Consequently, this area will be the focus of follow-up drilling in subsequent campaigns.

Exploration drillholes QVD-419 and QVD-420 have successfully identified silver mineralization on the Mani exploration target, located 700 to 800 meters to the south of the Yaxtche Deposit, where surface sampling identified high silver grades.

QVD-420 returned an intercept of 36 g/t Ag over 14.00 meters, including 204 g/t Ag over 2.00 meters, while QVD-419 returned anomalous silver values of 30 g/t Ag over 23.00 meters.

Anomalous silver values refers to geochemical assay results that indicate silver concentrations exceeding the natural background levels typically found in unmineralized country rock.

The El Quevar project is located in the north of Argentina, in the province of Salta. In 2024, The Fraser Institute voted Salta Latin America's top mining jurisdiction.

Salta has implemented a Provincial Plan for Sustainable Mining Development 2030, which includes infrastructure, education, and state modernization initiatives.

"The Government of Salta intends to ensure the development of the mining industry," states the 2030 Plan, "including the production of minerals such as gold, copper, lithium and silver."

Major mining companies operating in Salta include Rio Tinto, First Quantum, Aldebaran, AbraSilver and Fortuna Mining.

Argenta Silver has completed preparations for the 2025-2026 Summer Drill Program. With a strong treasury of approximately C$23 million, the Company confirms that the Program -- scheduled to continue until June 2026 -- is fully funded and ready to commence.

Scheduled for the Southern Hemispheres summer, this campaign is expected to start November 1, 2025, and involve significant drilling, with a target range of 12,000 to 15,000 meters.

Capital allocation will be directed as follows:

o 60% to the New Discoveries Program.

o 40% to the Resource Expansion Program; and

By running both exploration programs simultaneously, Argenta underscores its aggressive approach that is key to advancing the potential resource expansion. Making new discoveries on a property that remains largely unexplored.

"Historically, 80% of the drilling on El Quevar went into the resource area," Marias told Guy Bennett, CEO of Global Stocks News. "There has been very little exploration done outside of the resource. Only 3% of the property has been properly explored. In the new drill campaign, we are going to balance that equation, because the potential for new discoveries is huge."

"Resource expansion is the low-hanging fruit," added Marias. "About 40% of the capital allocation will go into resource expansion, and 60% will be allocated to aggressive exploration outside of the resource."

Note: all intervals shown in this release are at 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 foundational Mineral Resource Estimate of the Yaxtch? 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 of silver from 0.31 million tonnes grading 417 g/t Ag [1.]
