Mine Life... Lock
SnapshotThe Great White Project (GWP) is high-grade kaolin asset delivering premium products over a 28-year mine life.

The GWP is construction ready with the required permits in place.

The plant construction has been segregated into a number of stages to ramp up capacity in line with projected demand.

Stage 1A+ supported by binding offtakes agreements for Andromeda’s premium ceramic kaolin.

Andromeda continues to progress the GWP towards a final investment decision.

As at October 2025:
• Credit Approved for a A$75M debt facility with Merricks Capital;
• Progressing with cornerstone investor for asset-level investment;
• Finalisation of cornerstone process subject to due diligence, approvals and agreement on terms.

High Purity Alumina (HPA) Project (PEA 2025)
Andromeda is advancing a HPA Project using Great White kaolin feedstock. Detailed integration planning between HPA Project and GWP will be established in future studies.

Deposit type

  • Sedimentary

Summary:

The Great White Project deposit is a naturally high purity, bright white kaolin with low levels of impurities, specifically Fe2O3.

The Project has highly valued kaolinite and halloysite mineral deposits with a world-class iron to alumina ratio2, outstanding mechanical strength, exceptional fired brightness, and distinctive rheological properties.

The orebody is predominantly quartz sands (~ 45 % - 55 %) and clay (~45 % - 55 % kaolinite and halloysite).

The kaolin is shallow lying and truncated at depth by a weathered granite.

Kaolin deposits, such as Great White, developed in situ by lateritic weathering of the feldspar-rich Hiltaba Granite.

The kaolin deposit at Great White is a sub-horizontal zone of kaolinised granite resting with a fairly sharp contact on unweathered granite. The kaolinised zone is overlain by loosely consolidated Tertiary and Quaternary sediments.

The deposit covers an area 1.7km east-west by 1.7km north-south and has an average depth below surface is 23.9m with a range of 10m in the west to 46m in the east. The deposit has an average thickness of 9.4m with a maximum thickness of 23.9m and with extremities modelled down to 1m.

The 34.6Mt of in-situ Bright White kaolinised granite yields 17.4Mt of minus 45 micron quality kaolin product.
