Golden Goose Resources (CSE:GGR) has completed geological mapping and channel sampling at its Gran Esperanza Project located in Negro province, Argentina.

Phase 1 exploration at the optioned property began in March.

Golden Goose embarks on mapping and channel sampling program at Gran Esperanza Project, Argentina — Richard Mills

Among the program’s highlights:

• Approximately 23.6 kilometres of vein structures with observed mineralization were mapped and sampled.
• 341 channel samples were systematically collected from 265 channels in the western sector of the property.
• 12 rock chip samples were collected from newly discovered veins in eastern sector.
• Assays are pending for all samples.

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-meter 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.

“We are pleased to finish this first phase of exploration at Gran Esperanza,” stated CEO Dustin Nanos in the April 22 news release.  “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.”

Field work

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 rock-chip samples 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.

Gran Esperanza Project

Among the project highlights are about 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 (NYSE:SCCO) and Patagonia Gold (TSXV:PGDC). SCCO is drilling a gold project and PGDC is developing its Calcatreu Project.

There are 10 km of historically mapped, low-sulfidation epithermal gold vein exposures, with veins widths averaging about 1.5 meters, and strike lengths ranging from 50 to 2,500m. 

Thirty trenches have been excavated exposing 2,937m of epithermal veins; 690 channel samples were collected, with reported grades up to 2m at 24 g/t Au, demonstrating high-grade potential from surface.

In total there are 1,674 rock samples, including grab, chip, channels and float. The veins are characterized by drusy quartz, banding, crustiform and carbonate replacement. The rock chip samples feature grades up to 24.4 g/t Au. 

Gran Esperanza contains several drill-ready targets in what Golden Goose says is an extremely attractive precious metal district. 

The project also benefits from excellent infrastructure — situated approximately 2 kilometers from a paved highway, with gentle topography and numerous secondary roads across the property.

Conclusion

Favorable structural controls and extensive vein exposures make Gran Esperanza a compelling drill-ready exploration target. The first-phase drill program improved Golden Goose’s understanding of the scale and structural controls. I look forward to the assay results from channel/ rock chip sampling, and details about the upcoming drill program.
