VANCOUVER, BC – TheNewswire - April 22nd, 2026 – Golden Goose Resources Ltd. (the “Company” or “Golden Goose”) is pleased to announce the completion of geological mapping and channel sampling at its Gran Esperanza Project (the “Project” or the “Property”), a highly prospective gold-silver property located in Río Negro Province, Argentina.

The program represents the first phase of a comprehensive field campaign designed to better define the epithermal vein system and refine priority exploration targets across the Property. Work included property-wide geological mapping, detailed structural mapping within key mineralized corridors, and systematic channel sampling across exposed quartz veins and associated alteration zones. Geological crews focused on characterizing lithological units, alteration assemblages, vein orientations, and structural controls on mineralization. Channels were cut perpendicular to vein trends at approximately 50-metre intervals and systematically sampled to assess grade distribution and strike continuity. The data generated from this program will support refinement of the Company’s geological model and assist in identifying high-priority targets for potential diamond drilling.

Highlights

• Approximately 23.6 kilometres of vein structures with observed mineralization mapped and sampled.  

• 341 channel samples systematically collected from 265 channels in western sector of the Property.  

• 12 rock chip samples collected from newly discovered veins in eastern sector.  

• Analytical results are pending for all samples and will be reported once received  

Field Work

Golden Goose recently completed their first field program at the Gran Esperanza project in Río Negro province, Argentina. Field work focused on regional geological and structural mapping of the entire Property, with newly discovered veins described within the eastern sector of the property (Figure 1). These newly discovered veins are interpreted as being hosted and related to an Upper Triassic to Lower Jurassic plutonic complex, although further work is required to confirm this interpretation. Veins observed in the eastern sector are characterized by milky quartz, generally exhibiting comb textures, minor oxide presence, and disseminated pyrite, and display evidence of ductile deformation, suggesting possible emplacement within regional shear zones. Twelve (12) rock-chip samples 1 were taken at these new veins.

Previously identified veins of the western sector are interpreted to be related to Permian to Middle Triassic plutonic to subvolcanic complexes of the region. The western sector was the subject of detailed structural mapping and systematic sampling across the 23.6 kilometers of identified veins (Figure 1). A total of 341 channel samples were collected from 265 channels that were cut perpendicularly to the vein trends. Channels were cut using approximately 50-meter spacings throughout the numerous quartz vein networks.

Sampling Procedures

Channel samples were collected from veins cut with a saw machine along continuous sections perpendicular to the mapped veins, with systematic and unbiased sampling. Rock-chip samples in the eastern sector were collected along continuous sections perpendicular to the mapped veins. In either case, samples were placed directly into sample bags, each containing two internal sample identification tags, then securely sealed by the geological team. Samples remained under the direct supervision of the geological team until shipped via courier directly to the Alex Stewart International Argentina laboratory in Mendoza, an ISO/IEC 17025 accredited independent analytical laboratory. Samples are prepared with P5 code and then analyzed with fire assay for gold (Au4-50) and multi-elements by ICP (ICP-AR 39). Silver (>200 g/t) over-limits are analyzed by gravity method (Ag4A-50). Seventeen (17) QAQC samples including blanks, Certified Reference Materials, and duplicates, were inserted into the analytical batch before shipping all material to the laboratory.

The Gran Esperanza Project:

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

• Located adjacent to a gold project being drilled by Southern Copper, highlighting the district’s active and growing exploration profile.  

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

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

Dustin Nanos CEO of Golden Goose Resources, commented:

“ We are pleased to finish this first phase of exploration at Gran Esperanza,” stated Dustin Nanos, CEO of Golden Goose Resources. “This initial phase of fieldwork has significantly improved our understanding of the scale and structural controls at Gran Esperanza. The extent of mapped mineralized veins and the discovery of new systems reinforce our confidence in the project’s potential. We are excited to receive the assay results and continue advancing toward defining high-priority drill targets. ”
