Credo Project
The Credo Project covers approximately 50 km² in the heart of the Ida Fault Lithium Corridor—a region of growing significance for both critical minerals and gold exploration in Western Australia.
This highly prospective project lies across two key geological domains:
- The Kunanalling Shear Zone in the northeast—an important regional structure known to host mineralised pegmatites and shear-related gold systems
- The Rowles Lagoon Biotite Monzogranite—a domed, post-regional folding (post-RFG) granitic intrusion that spans the central and northwestern parts of the project
Geological Prospectivity
Unlike other Greta Minerals projects, the Credo Project displays limited surface evidence of greenstone lithologies overlaying the granites. However, low-amplitude aeromagnetic anomalies in the western and southern areas may indicate buried greenstone rafts, potentially preserved under sandy lateritic caps. This interpretation is supported by historical drilling nearby, which intersected basaltic rocks in similar geophysical settings.
The biotite monzogranite itself is structurally complex, with two dominant fracture systems:
- A northwest-southeast trend aligned with the central anticlinal axis
- A northeast-southwest trend consistent with regional tension shears linked to the Kunanalling Shear Zone
These structures host extensive pegmatite and quartz veining, including:
- Medium-grained pegmatites containing quartz, feldspar, biotite, minor cassiterite, and rare tourmaline
- Multiple quartz vein generations, with the second phase displaying iron-rich, anastomosing textures and evidence of sulphide mineral pseudomorphs
Such mineralogical assemblages are characteristic of fractionated granitic systems capable of hosting lithium-caesium-tantalum (LCT) pegmatites and intrusion-related gold.
Exploration Outlook
Geological and geophysical evidence suggests:
- The western and southern portions of the project may conceal greenstone lithologies, prospective for shear-hosted mineralisation
- The central and northeastern zones, being exposed biotite monzogranite, offer strong potential for intrusion-hosted lithium and gold deposits
These interpretations, coupled with proximity to key structural corridors and fertile granites, make the Credo Project a compelling dual-target opportunity within one of Australia’s most dynamic mineral belts.Ongoing exploration will leverage advanced geochemical techniques, including UltraFine+™ soil analysis, to refine target zones and validate subsurface potential.
