Wudinna Project
- Confirmed ionic REE mineralisation where ANSTO metallurgical testing has confirmed MREO recoveries up to 58% and HREO recoveries up to 65% at pH3 over six hours with low acid consumption
- Unique geological occurrence that lends itself to in situ recovery (ISR) mining, a low-cost, low-disturbance mining process that could be integrated into existing land practices
- Regionally scalable – nearly 495 km2 of prospective palaeo-channel across the land tenure
- 279,000 Oz defined JORC Gold Mineral Resource Estimate
- 22 orogenic gold targets, with significant grades of between 16 g/t and 37.4 g/t gold outside of the current resource
- Shallow resource – all ounces occur within 200m of surface, presenting as low cost, camp scale open pit extraction
- Potential additional gold resource growth through infill and further extensional drilling
- Enhanced economics following unique discovery of critical rare earth elements overlying gold mineralisation
- JORC Rare Earth Mineral Resource Estimate of 41.6 Mt occurs above and proximal to defined 129,000 Oz of gold resources at the Baggy Green and Clarke prospects
- One adjacent exploration tenement (Corrobinnie – 100% Cobra Resources) covering 532 km2 sits outside the Wudinna Project and is prospective for orogenic lode gold and rare earth mineralisation
- Excellent existing infrastructure
- Unique opportunity to advance economically beneficial combination of gold and rare earth resources
Next Steps
- Capitalise on the significance of confirmed ionic rare earth discovery at Boland prospect and commence a scope of work that includes:
- Mineralogical and in situ leach studies – drilling of 3-5 core holes to determine distribution of rare earths within clay bands, identify parameters for future in situ leach testing, define appropriate future composite sample lengths, and enable advancement of metallurgical testing to ultimately produce a rare earth carbonate for commercial marketing
- Monitoring well installation – to enable baseline monitoring and analysis of aquifers
- Resource drilling – Aircore (AC) drilling aimed at expanding footprint of ionic rare earth mineralisation
- Maiden Boland Mineral Resource Estimate
- Regional palaeo-channel testing – AC drilling testing the concept within the Corrobinnie palaeo-channel and on other Cobra tenements
- Further metallurgical testing to optimise recoveries and test further zones of mineralisation
- Improve gold and REE resource confidence to support a project scoping study
- Test extension targets across gold resources with the aim of adding low discovery cost ounces
