The area covered by the Golden Grove mining leases, covering approximately 129 km2 has a history of discovery.
The Golden Grove mining leases cover all known occurrences of the Golden Grove formation and are also considered prospective for gold within the overlying formations. However, despite the maturity of Golden Grove as a mineral province, the Golden Grove tenements remain relatively under‑explored with limited exploration drilling undertaken outside the areas of known mineralisation at Scuddles, Gossan Hill and Gossan Valley (and immediate surrounds). In particular, historic exploration has focused on identifying sulphide mineralisation within 400 m of surface (other than at Scuddles, Gossan Hill, Gossan Valley and surrounding areas where drilling associated with known mineralisation has extended to depths up to 1.8 km).
