(via TheNewswire)

VANCOUVER, BC – January 29, 2026 – TheNewswire - Golden Goose Resources Ltd. (the “Company” or “Golden Goose”) is pleased to announce that it has entered into a Definitive Agreement with Valcheta Exploraciones S.A.S. (“Valcheta”) to acquire up to a 100% interest in the Gran Esperanza Project (the “Project”), a highly prospective epithermal gold-silver property located in Río Negro Province, Argentina.

The execution of the Definitive Agreement represents a significant corporate milestone for Golden Goose and further reinforces the Company’s strategy of securing district-scale, high-grade precious metal assets in proven and emerging mining jurisdictions.

PROJECT HIGHLIGHTS – High-Grade, District-Scale Opportunity

Gran Esperanza Project – Río Negro, Argentina

• ~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.  

• Surrounded by major operators, including Southern Copper, and located near the Calcatreu Project which is currently under development  

• 10 km of historically mapped low-sulfidation epithermal gold vein exposures (Figure 1), with veins averaging ~1-5 metres in apparent width:  

  • 2,900 m of trenching with 690 channel samples collected;  

  • Channel sample grades reported up to 2.0 m at 24.0 g/t Au, demonstrating high-grade potential from surface  

• Several drill-ready targets in an extremely attractive precious metal district.

Project Scale, Access, and Geological Upside

• Approximately 44,400 hectares of year-round accessible terrain in the Los Menucos District within the North Patagonian Massif.  

• Benefits from excellent infrastructure – situated approximately two kilometres from a paved highway, with gentle topography and numerous secondary roads across the property.  

• Adjacent to a gold project currently being drilled by Southern Copper, highlighting the district’s active and growing exploration profile (Figure 1).  

• The Project’s extensive land position and the distribution of mapped epithermal veins across the property highlights the potential for district-scale mineralization at Gran Esperanza (Figure 1).  

Historical Exploration at the Gran Esperanza Project

• Mapped ~10 kilometres trend with low-sulfidation epithermal veins;  

• Veins average ~1-5 metres in width, with exposed vein strike-lengths ranging from 50 to 2,500 metres  

• 30 trenches excavated, exposing 2,937 metres (apparent length) of epithermal veins;  

• 690 continuous channel samples collected;  

• 1,674 total rock samples, including grab, chip, channels, and float  

• Veins characterized by drusy quartz, banding, crustiform, and carbonate replacement.  

• Historical surface sampling highlights include  

  • Channels  

    • 2.0 metres at 24.0 g/t Au  

    • 5.0 metres at 13.1 g/t Au  

    • 1.3 metres at 11.5 g/t Au  

    • 3.0 metres at 4.4 g/t Au  

    • 0.2 metres at 99.0 g/t Ag and 2.8% Cu  

    • 1.2 metres at 129.0 g/t Ag and 3.5% Cu  

    • 0.3 metres at 52.0 g/t Ag  

  • Rock chip samples  

    • Grades of up to 24.4 g/t Au  

a True widths of mineralized zones and veins described in historical channel cuts and mapping have not yet been confirmed at this time and will require additional follow-up .

b Grab, chip, and float samples are selective by nature and are not necessarily indicative of mineralized zones.

Golden Goose Management Site Visit at Gran Esperanza

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.

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.

Option Terms

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:

The Project is subject to a 1.0% net smelter return (“NSR”) 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. Exploration expenditures may be substituted, in whole or in part, with cash payments to Valcheta.

Joint Venture Structure – Clear Path to 100% Ownership

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.

Management Commentary

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.”

Qualified Person

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.

Quality control

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). The Company has relied on the internal lab QAQC procedures for the surface sample analysis. ASI Argentina is independent of the Company.
