Redstone Advances Saturn Project Near BHP’s Nebo Babel Deposit

Strategic Location Next to BHP’s Nebo Babel

Redstone Resources Limited (ASX:RDS) is turning the spotlight onto its recently granted Saturn Project, a 330 square kilometre exploration ground in Western Australia’s West Musgrave region. The project sits squarely within the Giles Intrusive Complex, a geological hotspot hosting BHP’s world-class Nebo Babel Cu-Ni-Co-PGE deposit just 25km west, and Terra Metals’ high-profile Dante PGE Reef and massive sulphide discoveries 40km northwest.

This proximity places Redstone’s Saturn tenure in the thick of a globally significant magmatic sulphide province, with the project’s potential underscored by the presence of multiple historical prospects that have already yielded encouraging copper, nickel, cobalt, and platinum group element (PGE) mineralisation.

Promising Historical Drilling at Halleys and Halleys NW

Despite limited historical exploration, drilling at the Halleys Cu-Ni-Co-PGE Prospect has defined a thick, pipe-like intrusive body with mineralised intersections including 58m at 0.35% copper, 0.08% nickel, and 0.21g/t combined Pt, Pd, and Au from 20m depth. Notably, a 15m interval within this returned 0.63% copper and 0.33g/t PGEs, highlighting zones of higher grade mineralisation.

Peak assays from Halleys include copper grades exceeding 1.1%, gold up to 1.2g/t, and combined PGEs over 1.1g/t in narrow intercepts, suggesting the potential for richer cores within the mineralised system. Halleys NW, a distinct PGE reef zone up to 45m thick, also shows promise with drilling intersecting 25m at 0.18g/t Pt+Pd+Au.

Last Frontier and Other Prospects Extend Potential Strike

Further along strike, the Last Frontier PGE Reef Prospect exhibits thick zones of anomalous PGEs over a 5km extension from Halleys NW, with drilling intersecting up to 15m at 0.18g/t Pt+Pd+Au. Sparse drilling leaves significant gaps along strike untested, pointing to substantial exploration upside.

Additional prospects such as Helena and Phoebe reveal anomalous copper and nickel mineralisation associated with layered mafic intrusions, reinforcing the Saturn Project’s broad base and precious metals potential.

Geological Setting Comparable to Major PGE Deposits

The Saturn Project’s namesake intrusion is a large, 13km-wide oval magnetic anomaly featuring concentric magnetic rings interpreted as successive magmatic pulses. This geophysical signature closely resembles that of the Panton Project in the Kimberley, which hosts a substantial resource of 92.9Mt at 1.5g/t PGM3E and significant nickel and chromium credits.

The broader Giles Complex, aged around 1.08 to 1.04 billion years, is one of the largest mafic-ultramafic layered intrusions globally, with PGE reefs often compared to South Africa’s Bushveld Complex; the world’s richest PGE source. The West Musgrave region’s tectonic setting further supports the prospectivity for large magmatic sulphide systems, akin to Canada’s Voisey’s Bay deposit.

Next Steps Include Drilling and Traditional Owner Engagement

Redstone is advancing access negotiations with Traditional Owners to enable on-ground exploration at Saturn. Concurrently, the company is preparing a reverse circulation (RC) drilling program at its flagship West Musgrave Project, targeting high-priority magnetic anomalies near the Tollu copper deposit, supported by a government co-funding grant.

Alongside these efforts, Redstone is progressing exploration plans for its recently acquired greenfields projects across Western Australia, targeting gold, lithium, and copper, aiming to leverage modern exploration techniques on underexplored ground.

Chairman Richard Homsany emphasised the project’s potential, noting the encouraging historical results and the strategic location within a world-class mineral province, offering a compelling opportunity for Redstone to build a significant sulphide mineralising system.
