Summary
Centrex Metals Limited (““Centrex”) hass appointed C
CITIC SMCC Process
P
Techn

nding
experts baseed in Brisbanee to complete
e a design revview of the grrinding and crushing circu it for the Oxle
ey Potassium
Project locatted near the Port of Gerald
dton in Westeern Australia.
The review w
will analyse both wet and dry
d crushing and grinding circuit config
gurations andd propose the
e optimal goforward design option to consider in the
t Prefeasibiility Study (“P
PFS”) currently underway ffor the projecct.

Centrex has already appo
ointed Canad
dian potash e ngineering exxperts Novopro to review tthe hydromettallurgical
circuit of thee process plan
nt, and Hatch
h for the pyro metallurgical circuit. Swiss licensor andd engineering
g firm Casale
have compleeted feasibilitty study desig
gns for ammoonia and nitric acid plants at the Oxley site, with cosst estimates
to be deliverred over the coming
c
montths. Centrex iss forming a mixed
m
consulting team of gglobal expertss in each of
the key desiggn fields with
hin the Oxley project.
The Prefeasiibility Study has
h commencced with a revview of a starrt-up high-value potassium
m nitrate speccialty
fertiliser (“NO
OP”) operatio
on and associated cost esttimates considered in the previous Scooping Study. This
T start-up
operation w
was based on only a fraction of the curreent Inferred Mineral
M
Resou
urces that inc ludes 38 million tonnes
at 10% K2O ((9% cut-off), from
f
the total of 155 millioon tonnes at 8.3%
8
K2O (6%
% cut-off). Infeerred Mineral Resources
to date coveer just 3kms of
o the overall 32km
3
strikingg rare ultrapo
otassic lava flo
ow that formss the basis off the project.
The Prefeasiibility Study will
w not only consider
c
the sstart-up NOP operation bu
ut also expan sion into bulk potassium
fertilisers.
