Golden Goose Resources Ltd. 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 high-grade epithermal gold-silver property located in Río Negro Province, Argentina. This acquisition represents a significant corporate milestone for Golden Goose and reinforces the company's strategy of securing district-scale, high-grade precious metal assets in proven and emerging mining jurisdictions.
The Gran Esperanza Project covers approximately 44,400 hectares of year-round accessible terrain in the Los Menucos District within the North Patagonian Massif, a region known for its high-grade precious metal potential. The property benefits from excellent infrastructure, situated approximately two kilometres from a paved highway with gentle topography and numerous secondary roads across the property. The project is surrounded by major operators, including Southern Copper, and located near the Calcatreu Project which is currently under development.
Historical exploration at Gran Esperanza has mapped approximately 10 kilometres of low-sulfidation epithermal gold vein exposures, with veins averaging approximately 1-5 metres in apparent width. Greater than 2,900 metres of trenching has been completed with 690 channel samples collected, with channel sample grades reported up to 2.0 metres at 24.0 g/t Au, demonstrating high-grade potential from surface. Historical surface sampling highlights include channels of 5.0 metres at 13.1 g/t Au, 1.3 metres at 11.5 g/t Au, and 3.0 metres at 4.4 g/t Au.
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, sampling records, land tenure, permitting status, and third-party technical reports. During a site visit in December 2025, the company collected four rock-chip samples from exposed mineralized veins, with three chip samples returning 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 $1,889,500 in cash payments and $2,599,000 in exploration 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, allowing the company to advance the project on an accelerated timeline if warranted by results.
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 that signing the Definitive Agreement for Gran Esperanza represents an important milestone and transformative step for the company. 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. The information collected to date positions Gran Esperanza as a compelling, drill-ready exploration project with the potential to rapidly deliver high-impact results.
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, 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.
