Old data gives MinRex new hope for Pacific Express

MINREX Resources has uncovered some 20-year-old legacy metallurgical results from the Houston Mitchell prospect as part of its pre-acquisition due diligence on the Pacific Express project in New South Wales, which show the prospect could potentially be developed into a standalone scandium deposit.

Boeing and Airbus need aluminium-scandium alloys to build their aircrafts.

The extensive legacy metallurgical studies undertaken by Jervois Mining were based on test work results from three laboratories that used different techniques to generate varying results.

The test work was designed to identify preliminary physical separation methods for ore to materially increase the head grade.

That in turn would reduce the volume of material to be processed while enriching the mineral fed into the proposed processing plants to extract scandium, cobalt and nickel, and vary chemical extraction methods to pinpoint the technique that recovered the highest proportions of scandium, cobalt and nickel.

As a result of scandium leaching on high-grade samples from the Houston Mitchell prospect, a 70% scandium recovery rate was achieved.
