SnapshotThe Medcalf Project is a high-grade titanium lump ore (HTLO) operation from several open-cut pits at the Medcalf Project. The processing philosophy has been considerably simplified as the project has been condensed to a direct shipping ore (DSO) operation.

The Medcalf Project is compliant with environmental, legal, and permitting requirements.

During the September quarter of 2023, Audalia Resources continued discussions with the Environmental regulators on finalising the conditions for the environmental approval (EPA). Completion of the primary environmental approval process remains the immediate priority of the Company.

Audalia Resources continues to assess funding alternatives to ensure the Company can continue exploration and evaluation activities at the Medcalf Project.

Summary:

The Medcalf Project lies in the Archaean aged Lake Johnston greenstone belt in the southern portion of the Youanmi Terrane, part of the Yilgarn Craton. This belt is a narrow north-northwest trending belt, approximately 110 km in length. It is located near the south margin of the Yilgarn Craton, midway between the southern ends of Norseman-Wiluna and the Forrestonia-Southern Cross greenstone belts.

The Medcalf Project lies within the Medcalf Layered Sill, which is a flat lying Igneous body which has intruded parallel to the enclosing volcanic strata basalt, prior to regional metamorphism.

Five separate zones of vanadium-titanium-iron mineralisation have been identified within the project area and named the Vesuvius, Fuji, Pinatubo, Kilimanjaro and Egmont prospects. In the Medcalf deposit vanadium, titanium and iron have been concentrated in a pyroxenite unit, which has subsequently been enriched in these metals through weathering and regolith formation.

In the mineralised areas the magnetite-rich sequence is deeply weathered, with +60m of saprolite showing vertical zonation of weathering minerals due to progressive weathering. The fully developed lateritic weathering profile is divisible into four zones. Starting from the top, they are lateritic residuum, mottled zone, saprolite and saprock. All the vanadium-titanium-iron mineralisation lies in the saprolitic zone.

The geological interpretation has divided the Medcalf Project into three broad, spatially unique areas:

- Egmont located to the west of the project area;

- Kilimanjaro located to the southeast and;

- Vesuvius in the central part of the project, which has been further sub-divided based on modelled fault boundaries:
- Vesuvius West;
- Vesuvius Central (including the Fuji prospect);
- Vesuvius East (including the Pinatubo prospect).
