Golden Goose Resources Ltd. has executed 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 aligns with the company's strategy of securing district-scale precious metal assets in established and emerging mining jurisdictions.
The Gran Esperanza Project encompasses approximately 44,400 hectares of year-round accessible terrain in the Los Menucos District within the North Patagonian Massif. The property benefits from excellent infrastructure, situated approximately two kilometres from a paved highway with gentle topography and numerous secondary roads. The project is surrounded by major operators, including Southern Copper, and located near the Calcatreu Project currently under development, highlighting the district's active exploration profile.
Historical exploration at the site has mapped approximately 10 kilometres of low-sulfidation epithermal gold vein exposures, with veins averaging 1-5 metres in width. Previous work includes 30 trenches exposing 2,937 metres of epithermal veins and collection of 690 continuous channel samples. Historical surface sampling highlights include channel samples grading 2.0 metres at 24.0 g/t Au and 5.0 metres at 13.1 g/t Au, demonstrating high-grade potential from surface. Additional information about the project's geological context can be found at https://www.newmediawire.com.
Prior to executing the agreement, Golden Goose completed comprehensive technical and legal due diligence, including a site visit in December 2025. During this visit, four rock-chip samples were collected from exposed mineralized veins, with three samples returning gold values above 2.0 g/t Au, including one sample grading 14.34 g/t Au. These results provide confirmation of the high-grade potential in the mineralized system.
Under the agreement terms, Golden Goose may earn up to a 100% interest through staged options consisting of cash payments totaling US$1,889,500 and exploration expenditures of US$2,599,000. The project is subject to a 1.0% net smelter return royalty, with Golden Goose having the right to purchase 0.5% for US$1.0 million. The company retains 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 as operator holding a 51% interest. The company may elect to proceed directly to 90% ownership by exercising the second option, deferring joint venture formation. Exercising the third option grants Golden Goose 100% undivided interest in the project.
Dustin Nanos, CEO of Golden Goose Resources, commented that the Gran Esperanza 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 positions Gran Esperanza as a compelling, drill-ready exploration project with potential to rapidly deliver high-impact results.
The technical content of the announcement has been reviewed and approved by Marie-Pier Boivin, P.Geo, Senior Geologist at Dahrouge Geological Consulting Ltd., a qualified person pursuant to National Instrument 43-101. During the December 2025 site visit, chip samples were collected along continuous sections perpendicular to mapped veins and sent to ASI Laboratories in Mendoza, Argentina for analysis using fire assay with atomic absorption finish on 50 grams of material.
This acquisition represents a significant corporate milestone for Golden Goose Resources, providing access to a high-grade precious metal asset in a proven mining district with established infrastructure and proximity to major operators. The project's extensive land position and distribution of mapped epithermal veins highlight potential for district-scale mineralization, offering investors exposure to advanced exploration opportunities in Argentina's growing mining sector.
