The Mawson South project (100% owned) is situated on the Northeast Coolgardie Mineral Field, 15km southwest of Legend Mining’s Mawson nickel-copper project.
The Mawson South project comprises one exploration licence (E28/2858) located some 285km east of Kalgoorlie, Western Australia, which covers an area of approximately 15 km2 within the Northeast Coolgardie Mineral Field (Kurnalpi District). Access to the tenement is via the maintained, unsealed Trans Line Access Road from Kalgoorlie for approximately 285 km (Kitchener Siding) before turning north onto the Cable Haul Road for approximately 18 km.
The Mawson South project area is located at the centre of the regional gravity high associated with the dense mafic-ultramafic intrusive rocks of the northern Fraser Zone. It is approximately 15 kilometres southwest of Legend Mining’s Mawson Ni-Cu deposit and approximately 150 kilometres northeast of IGO Limited’s Nova-Bollinger Ni-Cu-Co mine. The Boonderoo Fault, located approximately 12km due east of the project area, represents the boundary between Mesoproterozoic metagabbro’s, granitoids and sediments of the Fraser Zone and granites of the Recherche Supersuite within the Nornalup Zone. The Boonderoo Fault is a major deep-seated crustal fault originating from the Albany-Fraser Stage I Orogeny.

The Mawson South project area has received relatively little previous exploration compared to elsewhere in the Fraser Range region. Early work (1970’s) in the area was concentrated on heavy mineral sands and uranium exploration although no specific work was completed on the ground currently covered by tenement E28/2858.
The first recorded exploration work undertaken within tenement E28/2858 was completed by Ponton in 2007 who held the ground until 2011, when it was surrendered.
The Mawson South project is well positioned within the northern Fraser Zone, located on the ridge of the regional gravity anomaly that defines the Fraser Zone and approximately 15 kilometres southwest of Legend’s Mawson Ni-Cu deposit. The project is considered prospective for both Nova-Bollinger and Mawson-style Ni-Cu- Co sulphide mineralisation.
