Golden Goose Resources Ltd. (the “Company” or “Golden Goose”) has entered into a Definitive Agreement with Valcheta Exploraciones S.A.S. to acquire up to a 100% interest in the Gran Esperanza Project, a highly prospective epithermal gold-silver property located in Río Negro Province, Argentina. The agreement represents a significant corporate milestone for Golden Goose and reinforces its strategy of securing district-scale, high-grade precious metal assets in proven and emerging mining jurisdictions.
The Gran Esperanza Project comprises approximately 44,400 hectares of year-round accessible terrain in the Los Menucos District, North Patagonian Massif, a region known for its high-grade precious metal potential. The property is surrounded by major operators, including Southern Copper, and is located near the Calcatreu Project which is currently under development. Greater than 10 km of historically mapped low-sulfidation epithermal gold vein exposures have been identified, with veins averaging approximately 1-5 metres in apparent width. Historical trenching has yielded channel sample grades up to 2.0 m at 24.0 g/t Au, demonstrating high-grade potential from surface.
Prior to execution of the Definitive Agreement, Golden Goose completed a comprehensive technical and legal due diligence process, including a detailed review of historical data, surface geology, and sampling records. As part of this process, the Company conducted a site visit in December 2025, during which four rock-chip samples were collected from exposed mineralized veins. Three chip samples returned gold values above 2.0 g/t Au, including one sample grading 14.34 g/t Au, providing confirmation of the high-grade potential in the mineralized system.
Under the Definitive Agreement, Golden Goose may earn up to a 100% interest in the Gran Esperanza Project through a staged option consisting of cash payments and exploration expenditures totaling US$1,889,500 in cash and US$2,599,000 in expenditures. The Project is subject to a 1.0% net smelter return royalty, of which Golden Goose has the right to purchase 0.5% for US$1.0 million. Golden Goose retains full flexibility to accelerate option payments or exploration expenditures at its discretion.
Upon exercising the First Option, Golden Goose and Valcheta will form a joint venture, with Golden Goose acting as operator and holding a 51% interest. Alternatively, the Company may elect to proceed directly to a 90% ownership position by exercising the Second Option, thereby deferring joint venture formation. Upon exercising the Third Option, Golden Goose will hold a 100% undivided interest in the Project.
Dustin Nanos, CEO of Golden Goose Resources, commented: “Signing the Definitive Agreement for Gran Esperanza represents an important milestone and transformative step for Golden Goose. The Project stands out due to its favorable structural and geological setting, confirmation of numerous surface-exposed vein networks, excellent historical reported grades, and outstanding site access. During a site visit in December, our team visited confirmed gold-mineralized veins on the property. Despite being preliminary, these results and observed vein density are very encouraging. The information collected to date positions Gran Esperanza as a compelling, drill-ready exploration project with the potential to rapidly deliver high-impact results. We look forward to advancing the project through systematic surface exploration programs on the property.”
The technical content of this news release has been reviewed and approved by Marie-Pier Boivin, P.Geo, Senior Geologist at Dahrouge Geological Consulting Ltd., a consultant of the Company, and a Qualified Person pursuant to National Instrument 43-101. During the December 2025 site visit by the Company, four rock-chip samples were collected from exposed mineralized veins at the Gran Esperanza Project. Chip samples were collected along continuous sections perpendicular to the mapped veins, transferred into sample bags with unique sample ID tags, and sealed, before being sent to a certified commercial laboratory (ASI Laboratories, Mendoza, Argentina). The gold analyses were completed by fire assay with atomic absorption finish on 50 grams of material (method Au4-50).
