Overview
The Tampu Kaolin Project (Tampu) comprises two granted exploration licences held by Corella, being exploration licences E 70/5235 and E70/5214, and is in close proximity to established infrastructure including the Corella owned storage facility.
Tampu has seen two historical and one modern phase of exploration drilling and metallurgical programs. This drilling has sufficiently determined the validity and potential of Tampu to host significant bright white kaolin mineralisation with very low levels of contaminants. Further drilling and metallurgical test-work will be required in order to achieve a JORC compliant resource at Tampu.
A JORC complaint MRE at Tampu stands at 24.7Mt with an average yield of 50% for 12.2Mt @ 36.5% Al2O3 of <45um, and is flat lying, shallow, open in all directions and simple open cut. The deposit has proven to be Australia’s premier specification bright white kaolin deposit with low impurities and a high average ISO brightness of 85%, with calcined brightness of 90.8%.
A recently completed scoping study for the Tampu project which investigated producing both Kaolin and HPA which has outstanding potential project economics with an NPV of $1B (78% IRR) and $4.6B (54% IRR) respectively.
Independent test-work has produced High Purity Alumina (HPA) and achieved both 4N and 5N purity using a simplified method, proving Tampu’s Kaolin as premier specification.
The known mineralised area at Tampu is contained on two freehold farming properties that are, for the most part, fully cleared of vegetation and intermittently cropped. Agreements are in place with the two property owners for the purposes of exploration drilling and sub-surface rights at the Tampu.
TAMPU MINERAL RESOURCE ESTIMATE
Corella Resources has defined a (JORC) Inferred Resource Estimate for the Tampu Kaolin Deposit of 24.7Mt of bright white kaolinised granite suitable for HPA specification, with a yield of 49% for 12.2Mt @ 36.4% Al2O3 reported in the less than 45-micron size fraction

TAMPU SCOPING STUDY
Scoping Study presents project economics for two mutually exclusive scenarios;
- 100% kaolin 200ktpa production or
- 100% HPA 40ktpa production
The Company’s strategic vision is the production of High-Purity Alumina (HPA) using its high-quality kaolin as a feedstock.

TAMPU EXISTING INFRASTRUCTURE
Corella Resources acquired the Tampu grain storage facility.
6.12Ha facility located only 2.5kms from Corella’s 24.7Mt Tampu deposit and will be pivotal for the proposed mining operations.
The site consists of a 3,750m2 (~15,000t) storage shed, road loading facility, weighbridge, site office with accommodation and a Telstra mobile tower nearby.
Existing infrastructure potentially saves time and expenditure for a fast ramp up of operations.
