The Rocklea Gold Project is situated west and south of the Rocklea Dome some 50km to the west of Paraburdoo and Tom Price.
The geology of the project area is dominated by the Hardey Formation, Bongal Formation and the Pyradie Formation within the Fortescue Group. The Rocklea Dome appears to have structural features wrapping around it which terminate at the NNW/W trending major crustal scale Ninjilgardy Fault System some 30km to the SW. It is splays off this main fault system that are the likely conduits for the mineralising fluids that are present at the Paulsens, Belvedere and Mt Olympus gold lodes with all these deposits of a similar age to the Karlawinda gold camp further east along the same crustal margin.
The ground covered by the tenements which make up the Rocklea Gold Project have geological similarities to the Paulsens Gold Mine, a significant high grade gold operation which was placed on care and maintenance in 2017 by Northern Star Resources having produced over 900koz at an average grade of 7.3g/t Au. More recently Paulsens was acquired by Black Cat Syndicate in June 2022 with production recommenced in December 2024 following an extensive near mine and regional exploration programme and is currently in ramp up phase producing a projected 9,500-11,000 ounces per quarter.
The gold mineralisation at Paulsens occurs where a gabbroic sill transects a metasedimentary unit adjacent to WNW-NW fault structures. Gabbroic sills, metasedimentary units and WNW-NW fault structures are all present within the Rocklea Project area.
The Rocklea Gold Project is adjacent to the regionally significant Ninjilgardy Fault which is a major crustal boundary. A number of significant gold deposits occur adjacent to the Ninjilgardy Fault, namely Black Cat Syndicate’s Paulsens Gold Operations (>1 moz Au), Kalamazoo Resources Ashburton Project Mt Olympus (1.44 moz Au) and Capricorn Resources Karlawinda Project (>2.1 moz Au).
