INITIAL METALLURGICAL TESTING
Initial bench scale metallurgical testwork was completed
on different sample types from mineralisation within
the conceptual open pit for the Constellation
deposit. This preliminary testwork was conducted
on samples comprised of reverse circulation chips
from several drill holes, predominantly across the
oxide and supergene mineralisation. Follow up test
work is using samples from diamond drill hole.
The testwork results indicate good copper
recoveries and saleable concentrate grades for
the supergene samples via flotation and indicates
that Tritton will be able to treat this material.
Recovery estimated from testing pure sulphide
ore indicates the ore behaves similar to other
deposits at the Tritton Copper Operations.
For the oxide mineralisation, testwork results
indicate heap leach recoveries for copper that
are consistent with recoveries experienced
previously at the Murrawombie heap leach.
The recoveries projected from this initial testwork are
consistent with those assumed in calculating the update
Mineral Resource estimate for the Constellation deposit.
Pure sulphide mineralisation is geologically very similar
to other deposits at the Tritton Copper operations.

MURRAWOMBIE EXPLORATION
Grade control drilling completed
at Murrawombie during FY2022
supports the current geological
interpretation, with follow-up drilling
required to further define smaller,
high-grade lodes. Additionally, the
latest drilling and returned assay
results have confirmed mineralised
intersections outside of the previously
reported Mineral Resource, which
will be followed-up with future drilling
campaigns. We are confident
that the mineralisation will be
significantly extended at depth.
