Summary
Centrex Metals Limited (““Centrex”) hass appointed C
Canadian bassed potash en
ngineering exxperts Novopro to analysee
and recomm
mend optimissations of its Oxley
O
Potassi um Project hydrometallurrgical circuit ddeveloped in a Scoping
Study comp
pleted last mo
onth. This work forms partt of the comm
mencement off a Prefeasibi lity Study for the project.
The Prefeasiibility Study will
w consider not only a staart-up potassium nitrate (““NOP”) speciaalty fertiliser operation,
o
but also covver second staage expansion into the bu lk potassium fertiliser marrket.
A start-up NO
OP operation
n and associated cost estim
mates in the previous Scoping Study w
were based on
n only a
fraction of th
he current Infferred Mineral Resources tthat includes 38 million tonnes at 10% K2O (9% cut-o
off), from the
total of 155 m
million tonnees at 8.3% K2O (6% cut-off)). Inferred Min
neral Resourcces to date coover just 3kmss of the
overall 32km
m striking raree ultrapotassiic lava flow thhat forms the basis of the project.

Preliminary engineering studies
s
includ
ding by Novoopro, will furth
her review the
e numerous ddesign option
ns
considered aand costed in
n the Scoping
g Study. Based
d on these studies the go-forward optioon will be cho
osen that
will be undeerpinned by a small-scale pilot
p testworkk program du
uring the Prefeasibility Studdy. The Prefe
easibility
Study is targgeted for com
mpletion by th
he end of 20177. Novopro will
w review the hydrometalllurgical sectio
on of the
project whicch includes leeaching and purification

off potassium chloride

from the molten ssalt roast circuit that
extracts potaassium from feldspar.
