==> picture [19 x 18] intentionally omitted <==

High grade, district scale titanium HMS discovery

Initial mineralogy results average >96% VHM content

Assemblage dominantly comprises high value titanium ores (rutile product and pseudo-rutile)

Deposit is close to surface and remains open to the north

• Additional saprolite HM zones under investigation

==> picture [19 x 18] intentionally omitted <==

==> picture [19 x 19] intentionally omitted <==

Coarse grained therefore likely to generate strong recoveries through conventional spiral technologies

Tier-1 mining jurisdiction of South Australia

Close to existing transport infrastructure provides access to global markets

Robust balance sheet to support ongoing studies and exploration with $9.3m cash at 31 March 2025

Management with a proven track record of discovery
