Maiden Sandras Mineral Resource Grows Finniss to 6.3Mt...

Maiden Sandras Mineral Resource Grows Finniss to 6.3Mt HIGHLIGHTS

• Maiden Inferred Mineral Resource Estimate for Sandras of 1.3Mt at 1.0% Li2O

• Finniss Project Global Mineral Resource is growing rapidly and now estimated to total 6.3Mt at 1.4% Li2O

• Additional Mineral Resource Estimates are planned over the next 2 months expected to result in an increased mine life at the Finniss Project aimed at further enhancing project economics: o Maiden Mineral Resource Estimate for Carlton Prospect in next 2 weeks o Additional Mineral Resource Estimations commencing in coming weeks on Hang Gong and the Lees-Booths-Link Prospects

• Potential for substantial upside in considering these new Mineral Resources in the current Definitive Feasibility Study (DFS);

• Core’s DFS work is focussed on mining and production of high-grade lithium concentrate near Darwin – with development anticipated to commence in 2019;

• The Finniss Project Total Mineral Resource is one of the highest-grade undeveloped lithium deposits in Australia;

• Considerable scope remains to further increase the Mineral Resource given the many additional lithium-rich pegmatites identified within Core’s large >500km2 of tenure at Finniss.
