Success Dome Project

Success Dome licence structural setting

Castle Minerals has a ~220km² exploration licence (E08/3257) prospective for gold and base metals centred on Success Dome in the Ashburton Basin (Fig 1).

The 70-block licence lies midway between Northern Star’s (ASX: NST) Paulsen’s gold deposit and Kalamazoo Resources’ (ASX: KZR) Ashburton deposit, within the same regional-scale structural corridor.

More locally, Success Dome lies immediately adjacent to the southern margin of the Hamersley Basin and 40km southwest of Castle’s Beasley Creek gold project.

Major thrust faults and sub-parallel shear zones highlighted in the regional magnetic and gravity data, combined with additional detailed geophysics data from previous explorers, brought this available area to Castle’s attention.

Dominant lithologies in the licence area comprise Duck Creek Dolomite in the north and Ashburton Group sediments to the south (Fig 2).

Two particular areas of interest have been identified. Target 1 is at the intersection of the regionally dominant Cheela Thrust Fault and a subsidiary shear zone. Target 2 is an area of deformation and offset of Ashburton Formation sedimentary rocks.

Success Dome is logistically well located southwest of the iron ore town of Paraburdoo and west of Tom Price in a region with excellent road, rail and air infrastructure plus mining support services.

A desktop review of historical exploration has commenced and publicly available geophysical data will be reprocessed. A first-pass reconnaissance sampling programme is planned.

The reprocessing by Castle of the regional aeromagnetic data covering the Success Dome precious and base metals project in the Ashburton region and the enhanced structural information obtained from that and an initial phase of mapping and reconnaissance sampling has provided an excellent guide for a planned initial phase of exploration.
