Golden Arrow receives environmental OK for San Pietro

Executive Summary

• Golden Arrow Resources Corp. received an Environmental Qualification Resolution (RCA) from Chilean authorities for its San Pietro copper-gold project in the Atacama region.
• The approval authorizes the installation of 80 additional drilling platforms, primarily at the Rincones and Colla deposits, enabling a major infill and stepout drilling program.
• The company plans to use this approval to upgrade resource categories, potentially increase average grades, and test for mineralization extensions, while also advancing new exploration targets like Noemi and Cerro Sur.

Key Details

• Regulatory Approval: Issuance of an Environmental Qualification Resolution (RCA) on November 6, 2025, by Chilean environmental authorities.
• Drilling Authorization: Approval allows for the installation of 80 additional drilling platforms, providing scope for detailed drilling to upgrade and expand resources.
• Target Areas: Primary focus on the Rincones and Colla deposits; also includes stepout drilling to test extensions between deposits and in open directions.
• Future Exploration Plans:
  • Complete infill drilling at Rincones and Colla to upgrade resource category and potentially increase copper and gold grades.
  • Conduct stepout drilling to test for mineralization extensions.
  • Advance new gold exploration targets, specifically Noemi and Cerro Sur, for drill testing in the new year.
• Environmental Compliance: The RCA includes environmental permits for waste management, sewage works, and closure. The process involved baseline studies on ecosystem protection, groundwater monitoring, archaeological surveys, and community interviews, submitted as an Environmental Impact Declaration (DIA).
• Project Location: San Pietro project is located in the Atacama region, approximately 100 kilometers north of Copiapo, Chile, on over 21,000 hectares.
• Current Resource Estimate (Inferred):
  • 2.5 million pounds of contained copper.
  • 770,000 ounces of contained gold.
  • Total tonnage: 492 million tonnes.
  • Average grades: 0.23% copper, 0.05 g/t gold, 99 g/t cobalt, and 14.43% iron.
• Ownership: Golden Arrow operates San Pietro through its 75%-owned Chilean subsidiary, New Golden Explorations Inc. (NGE).

Notable Quotes

• "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 stepout 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." — Brian McEwen, Vice-President, Exploration and Development
