Golden Arrow Resources receives Environmental Approval for San Pietro Project, Chile

Golden Arrow Resources Corp. [TSXV: GRG; FSE: G6A; OTCQB: GARWF] reported that a significant permitting milestone has been achieved for the San Pietro Copper-Gold Project in the Atacama Region, Chile.

Following an extensive process spanning over a year, an Environmental Qualification Resolution (RCA) has been issued by the Chilean authorities responsible for environmental matters. The RCA includes several authorizations and most importantly allows for an additional 80 drilling platforms, mainly in the area of the Rincones and Colla deposits. Each platform is a location where one or more drill holes can be executed, which provides the company a large scope for the next phase of detailed drilling to upgrade and expand the resources.

Brian McEwen, Golden Arrow VP Exploration and Development stated, “We are pleased to have reached this milestone, which went very smoothly thanks to our professional team in Chile. This approval allows us to complete the infill drilling program at Rincones and Colla to both upgrade the resource category and potentially increase the average grades of copper and gold mineralization.

“The next program will also include step-out drilling to test for extensions to mineralization, both between the deposits and in several directions that remain open. In addition to those large-scope programs envisioned at our existing deposits, we are working to advance our exciting new gold exploration targets like Noemi and Cerro Sur to be ready for drill testing in the new year.”

Independent consulting group Ambiental y Sectorial SpA were commissioned to complete the environmental assessment process for the requested areas, which involved conducting baseline studies focused on ecosystem protection, groundwater monitoring, and archaeological surveys, as well as studies and interviews with local communities.  The work was compiled and submitted as a Environmental Impact Declaration (Declaración de Impacto Ambiental; “DIA”) to the relevant authorities in the Atacama Region, Chile.

The DIA evaluation process concluded successfully with the issuance of an RCA on November 6, 2025, which authorizes the implementation of the requested work and establishes environmental obligations in relation to that work. The RCA includes environmental permits related to waste management, sewage works, and closure, among others.

The San Pietro Project targets the discovery of multiple deposits of copper, gold, iron and cobalt (IOCG) on over 21,000 hectares located approximately 100 km north of Copiapó in the Atacama Region, Chile. To date, Golden Arrow has completed an initial Mineral Resource Estimate for the Rincones and Colla IOCG deposits that includes 2.5 Mlbs of contained Cu and 770,000 oz contained Au in the Inferred category (492 Mt with an average grade of 0.23% Cu, 0.05 g/t Au, 99 g/t Co and 14.43% Fe.

Situated between and adjacent to Capstone Copper’s Manto Verde Mine property and Santo Domingo Project, San Pietro is in the centre of a new IOCG district within an active, well-developed mining region that is home to all the major IOCG deposits in Chile.

Golden Arrow operates San Pietro through its 75%-owned Chilean subsidiary, New Golden Explorations Inc.

Golden Arrow is actively exploring its flagship property, the advanced San Pietro IOCG project in Chile, and a portfolio that includes nearly 125,000 hectares of prospective properties in Argentina.

The company is a member of the Grosso Group, a resource management group that has pioneered exploration in Argentina since 1993.
