Coolgardie Lithium Projects

Ore Resources holds two high-quality lithium exploration assets at the 100%-owned Kangaroo Hills Lithium Project (KHLP) and Miriam Lithium Project (Miriam). The combined KHLP and Miriam tenements stretch over 11 km, covering the key interpreted lithium trend within the Coolgardie greenstone belt.

Kangaroo Hills Lithium Project

The Kangaroo Hills Project represents a high-quality hard rock lithium discovery located approximately 17 km south of the township of Coolgardie. Spodumene mineralisation within lithium-caesium-tantalum (LCT) pegmatites was discovered during regional exploration drilling in late 2022.

Exploration at KHLP revealed Big Red, a near-surface, shallow-dipping, thick, and high-grade spodumene-bearing lithium deposit. Big Red’s known mineralised system extends over 900 m and remains open along strike and down dip.

The best intercepts to date at Big Red include:

• 29m @ 1.36% Li₂O from 38m (KHRC011)
• 31m @ 1.13% Li₂O from 86m, incl. 20m @ 1.43% Li₂O (KHRC166)
• 27m @ 1.32% Li₂O from 64m (KHRC017)
• 23m @ 1.19% Li₂O from 44m (KHDD001)

Initial metallurgical testing conducted in February 2024 confirmed that spodumene is the dominant lithium mineral (~90% of the Li₂O) within the Big Red pegmatite. Test results indicated that Big Red will be well-suited to conventional Dense Media Separation (DMS) and Froth Flotation separation techniques. A hybrid flowsheet design incorporating both methods is expected to optimise processing outcomes.

Significant intercepts from the recent discovery at Potoroo include:

• 14m @ 1.04% Li₂O from 108m (KHRC178)
• 8m @ 0.51% Li₂O from 155m (KHRC172)

Miriam Lithium Project

Miriam is located immediately north and contiguous with KHLP. It comprises thirteen discrete outcropping pegmatites across an area approximately 6.0 km by 1.5 km. With a large untested strike extent, Miriam represents a promising greenfield exploration opportunity.

Historical soil sampling at Miriam identified large lithium anomalies extending from an outcropping spodumene-rich pegmatite, with weathered rock samples grading up to 1.85% Li₂O.

The primary exploration target at Miriam spans approximately 1.6 km in strike, complemented by a second trend of approximately 600m. With no historical drilling for lithium, Miriam offers untapped potential for future exploration success.
