(MENAFN- Newsfile Corp) Toronto, Ontario--(Newsfile Corp. - November 21, 2025) - AbraSilver Resource Corp. (TSX: ABRA) (OTCQX: ABBRF) ("AbraSilver" or the "Company") is very pleased to announce that it has formally submitted its application for the Diablillos silver-gold project to be included under Argentina's Large Investment Incentive Regime ("RIGI").

RIGI is a recently implemented federal investment framework designed to attract and accelerate major development projects in Argentina by providing long-term fiscal stability agreements and a competitive suite of tax, customs, and foreign-exchange benefits. Both Salta and Catamarca Provinces, where Diablillos is located, have opted into the regime.

Approval under RIGI will significantly increase project economics and enhance overall investment certainty as Diablillos moves into its next phase of development.

John Miniotis, President and CEO of the Company stated "This submission marks another major milestone for AbraSilver as we continue to de-risk and advance Diablillos. With our RIGI application now submitted and pending governmental review, we look forward to a decision in early 2026, which will bring transformative benefits for the project as we continue advancing toward a construction decision next year."
