Abrasilver Resources Company (lesson-TSX, The best-OTC) announced an updated Mineral Resource Estimate (MRE) for the Diablillos Silver and Gold Project in Argentina.
The company said the updated MRE shows significant growth across the project, with measured and indicated resources now at 232 million tonnes, containing approximately 248 million ounces of silver and 2.54 million ounces of gold (454 million ounces of silver equivalent AgEq). Metallurgy in the measured and indicated resource is up 25% for silver, 48% for gold, and 30% for AgEq, compared to a previous July 2025 estimate.
The updated MRE includes approximately 13,270 meters of additional drilling completed since the previous MRE, bringing the total database to more than 170,000 metres. The latest estimate includes 232 million tonnes of silver grading 33 g/t and 0.34 g/t gold containing 248 million ounces of silver and 2.54 million ounces of gold (454 million ounces AgEq), measured and indicated as amenable to both tank and pile leaching methods.
The new estimate reflects growth at all five deposits in the Diablillos – Oculto, Jack, Fantasma, Laderas and Sombra, driven by recent drilling success, improved geological understanding, and updated economic assumptions. It is based on drilling through December 31, 2025, and does not include any of the Phase VI drilling completed since then.
Oculto’s measured and indicated tonnage rose 45%, with silver up 15% and gold up 31%.
The expanded MRE supports the ongoing definitive feasibility study for the tank leaching process and a concurrent preliminary economic evaluation to evaluate the pile leaching option, both of which are targeted for completion by the end of the second quarter of 2026.
AbraSilver shares advanced on the news, rising 5.8%, or $1.10, to $18.31. Shares are currently trading in a 52-week range of $18.00 to $2.93.
AbraSilver is a gold, silver and copper exploration company with projects in Argentina and Chile. Its shares were recently listed for trading on the TSX. AbraSilver’s primary focus is the exploration and development of the Diablillos Project, a high-sulphate, gold-silver deposit located in the Salta Province of Argentina.
The 80-square-kilometre Diableus property is located in Argentina’s Puna region – the southern extension of the Altiplano in southern Peru, Bolivia and northern Chile. The project was acquired from SSR Mining Inc. (SSRM-TSX, NASDAQ, SSR-ASX) in 2016.
“This update reflects the continued growth of our core deposit while also highlighting the large-scale heap leaching opportunity that can enhance the overall development profile of the project,” said Joh Miniotis, President and CEO of AbraSilver. “With DFS on track for completion in the second quarter of 2026, we are progressing towards a formal construction decision, while continuing to generate additional value through continued exploration success.”
