HIGHLIGHTS • High grade BP33 Lithium Resource upgraded by 51% to 2.15Mt with a coincident grade increase to 1.5% Li2O • BP33 Lithium Resource is now classified as Indicated and Inferred • Size and average grade of Finniss Project Lithium Mineral Resource has also increased and now stands at 5Mt at 1.5% Li2O • Additional mining inventory defined is expected to result in a longer mine life at the Finniss Project, and further enhance the robust economics • Maiden Resource estimate for Sandras expected to add further to Project Mineral Resources later this month • The Finniss Project Definitive Feasibility Study (DFS) remains on track for completion in late November 2018 • DFS focussed on mining and production of high-grade lithium concentrate near Darwin - development planned to commence in 2019 • Finniss Project Lithium 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
