Rare Earths
Browns Range Heavy Rare Earths Project

Outstanding Diamond Drilling results confirm and extend total
rare earth oxide (TREO) mineralisation at Wolverine, with
intersections up to 28m @ 1.77% TREO and 47m @ 0.82% TREO

Metallurgical testing confirms simple and low cost processing to
produce high grade yttrium and dysprosium-rich xenotime
concentrates

High recoveries of yttrium (>80%) using magnetic separation as the
primary beneficiation technique followed by simple flotation

Prices for yttrium increase up to 45% driven by demand for
phosphors

Initial operating costs studies complete, confirming robust project
economics

Regional geochemical testing identifies two new high grade HREE
(Heavy Rare Earth Elements) targets, confirming prospectivity of
the region and further growth potential
