BRYAH BASIN PROJECT | Cu-Au VMS & OROGENIC GOLD
Parbo's largest contiguous position in the Bryah Basin
The same basin stratigraphy that hosts DeGrussa and Monty – with multiple drill-ready targets never tested at depth.
- 461 km² tenure package located ~70 km north-northeast of Meekatharra, WA, and just 10 km east of Parbo's Mount Padbury Project
- Sits within the Palaeoproterozoic Bryah Basin - the same mineral province that hosts the DeGrussa, Monty and Horseshoe Lightse copper-gold deposits
- Dual commodity potential: VMS copper-gold mineralisation and Capricorn-age orogenic gold
- Encouraging shallow gold and copper intercepts already recorded at Narracoota, Durack Well, Brian's Mill and Holden's Well
- Narracoota (copper) and Brian's Mill (gold) are the priority targets for the next phase of diamond, RC and AC drilling
OVERVIEW | MURCHISON MINERAL FIELD | WESTERN AUSTRALIA
A proven VMS province, never properly tested
The Bryah Basin Project is located approximately 90km NNE of Meekatharra, roughly 10-15km from Parbo’s Mount Padbury Project. The Bryah Basin hosts world-class Cu-Au deposits including DeGrussa (ASX:SFR – 14.33Mt @ 4.6% Cu, 1.6g/t Au), Monty and Horseshoe Lights, demonstrating the basin’s prospectivity for major copper-gold discoveries.
Parbo’s tenure captures the full suite of Bryah stratigraphy – the Karalundi, Narracoota and Ravelstone Formations — across a multistage rift basin subsequently overprinted by the Capricorn Orogeny. This geological setting is directly analogous, in key respects, to the regional environment hosting DeGrussa, Monty and Horseshoe Lights.
The project targets DeGrussa-style Cu-Au VMS mineralisation and Capricorn-age orogenic gold systems within a rare triple-junction rift and basin-margin setting.
The Opportunity
- A proven mineral system, on our doorstep. The project sits within the same Bryah Basin stratigraphy and structural setting that hosts DeGrussa and Monty. To put the scale in context, DeGrussa's total mineral resource stands at 14.33 million tonnes grading 4.6% copper and 1.6 g/t gold, giving us a real, working exploration model to test against.
- Demonstrated mineralisation, shallow and untested at depth. Historical drilling has already returned encouraging gold and copper intercepts at multiple prospects, almost all within the top 100 m and often less than 50 m downhole, clear evidence of a live system that simply hasn't been drilled deep or well enough.
- Multistage structural preparation. Early rift faulting followed by Capricorn Orogeny overprinting has produced a dense network of shear corridors and fault intersections, the kind of structural plumbing that channels and traps mineralising fluids.

3 Priority Prospects
NARRACOOTA
Our priority copper target, hosted in mafic-ultramafic volcanics of the Narracoota Formation, the same rock package that hosts DeGrussa and Monty. Historical drilling has returned shallow gold and copper intercepts, and untested VTEM and gravity anomalies point to a larger system at depth. Narracoota is earmarked for a diamond and RC program designed to test the concept of a tier-1 concealed copper deposit.
BRIAN"S MILL
Shallow, structurally controlled gold mineralisation along the Narracoota Trend, including 6m @ 2.4g/t Au from 17m (NAC001). Previous drilling was too tightly spaced and poorly targeted to test the prospect’s real upside. Our planned program combines closer-spaced RC with step-out aircore drilling to test both grade continuity and scale.
DURACK WELL
Along-strike extension of the Brian’s Mill–Narracoota trend, with historic intercepts including 25m @ 0.5g/t Au from 48m to EOH (HDR0041, incl. 3m @ 2.1g/t Au from 48m) .It remains a key part of the broader Area 2 target zone earmarked for follow-up structural and geophysical work.
