Near the mine,
distinct opportunity
West Santa Fe is a sediment-hosted epithermal gold and silver system located 15 kilometres west of the Santa Fe Mine.
Recent drilling has returned thick, shallow oxide intercepts from surface. Combined with encouraging cyanide recovery results and a fully permitted drill program, the project provides a second potential resource centre within Lahontan's Nevada portfolio.

Metallurgy
Oxide material responds to cyanide leaching
cyanide recovery
cyanide recovery
Preliminary bottle-roll testing reported encouraging recoveries for both gold and silver, supporting continued evaluation of the shallow oxide system.
Regional setting
Part of an active Nevada mining district
The project sits within Nevada's Walker Lane, close to the Santa Fe Mine, the Isabella Pearl operation and existing energy infrastructure.

Work program
Building toward a maiden resource
The current exploration strategy is designed to extend known shallow mineralisation, test new targets and assemble the geological and metallurgical data required for a first mineral resource estimate.
- CompleteBLM approval for drilling
- Complete2025–2026 oxide drilling
- CompleteInitial cyanide recovery test work
- Planned3,500 metres of additional drilling
- TargetMaiden Mineral Resource Estimate
