GOLDEN ARROW FILES TECHNICAL REPORT FOR SAN PIETRO COPPER-GOLD-IRON-COBALT PROJECT, CHILE

Golden Arrow Resources Corp. has filed the National Instrument 43-101 technical report supporting disclosure of the first mineral resource estimate (MRE) for the San Pietro copper-gold-iron-cobalt project in Chile, as reported on Feb. 28, 2025. Table 1 summarizes the MRE.

The report, titled "Mineral Resource Estimate for the San Pietro Copper-Gold-Iron-Cobalt Project, Atacama Region, Chile," with an effective date of Jan. 24, 2024, is available under the company's profile on SEDAR+ and will be posted to the company's website.

Cautionary statement regarding mineral resources

The mineral resources disclosed in this press release conform to NI 43-101 standards and guidelines and were prepared by independent qualified persons. The above-mentioned mineral resources are not mineral reserves as they do not have demonstrated economic viability. The quantity and grade of the reported inferred mineral resources are conceptual in nature and are estimated based on limited geological evidence and sampling. Geological data are sufficient to imply but not verify geological grade and/or quality of continuity. An inferred mineral resource has a lower level of confidence relative to a measured or indicated mineral resource and constitutes an insufficient level of confidence to allow conversion to a mineral reserve. It is reasonably expected, but not guaranteed, that the majority of inferred mineral resources could be upgraded to measured or indicated mineral resources with additional drilling.

Qualified person

Brian McEwen, PGeol, vice-president, exploration and development, to the company and a qualified person as defined in NI 43-101, has reviewed and approved the contents of the news release.

About the San Pietro IOCG (iron oxide copper-gold) project

The San Pietro project covers approximately 20,000 hectares, 100 kilometres north of Copiapo within an active, well-developed mining region that is home to all the major IOCG deposits in Chile. San Pietro is centrally located in a potential new IOCG-plus-cobalt district, between and adjacent to Capstone Copper's Mantoverde copper mine property and Santo Domingo copper-iron project, as well as other IOCG exploration and development properties.

The project is hosted by andesite units in a Cretaceous-aged volcano-sedimentary sequence associated with intrusive rocks, including granodiorites and diorites of similar age. The project is located east of the Atacama fault system, a major north-south regional structure, which was instrumental in controlling the emplacement of the ore deposits in the area.

Mineralization at San Pietro is typical of an IOCG system, with the addition of cobalt, and occurs in mantos, breccias and veins within a zone of alteration characterized by an association of actinolite, epidote, chlorite and scapolite. The mantos are replacement of andesite by magnetite and sulphides, with a roughly southeastern strike and a gentle dip to the southwest. Breccias and veins crosscut the mantos, are often subvertical, and are filled with specularite and sulphides.
