IMX Resources Announces Significant Improvement in Mt Woods Magnetite Metallurgical Performance

IMX Resources Announces Significant Improvement in Mt Woods Magnetite 
Metallurgical Performance 
Highlights 
- Increase in anticipated overall yield from previous test work
programs to approximately 28.5% which includes the ability to
beneficiate mill feed to around 35% iron through dry magnetic
separation on crushed product, delivering a sizeable reduction in
estimated operating costs. 
- High grade, low impurity magnetite concentrate of above 68.5% iron
at relatively coarse grind size of 75 to 80 micron (P80). 
- Alternative coarse direct sinter feed product at 65% iron can still
be produced with the same flow sheet giving the option to maximize
project returns. 
PERTH, AUSTRALIA -- (Marketwire) -- 03/18/13 -- IMX Resources Limited
(TSX:IXR)(TSX:IXR.WT)(ASX:IXR) ('IMX' or the 'Company') is pleased to
announce that it has received results from the recent metallurgical
test work program carried out by Amdel Pty Ltd in Perth. These
results indicate a significant improvement in metallurgical
performance from previous testing. The additional metallurgical
testing was carried out on diamond drill core samples from six
spatially distributed drill holes from the Snaefell resource on the
Mt Woods property in South Australia.  
The drill intersections were selected to reasonably represent the
inferred magnetite resource at Snaefell, currently 569 Mt @ 27.1% Fe
(using 18% Fe cut-off), which has been the subject of previous
metallurgical testing and an internal Concept Study. The previous
metallurgical test work program carried out in 2011 was carried out
on reverse circulation drill chips that introduce a natural bias due
to the drilling technique, which is not present when testing material
from diamond drilling. A brief summary of the test work and detailed
results are attached in Appendix 1. 
Managing Director Neil Meadows commented, "The updated test work
indicates a significant improvement in yield, a key economic driver
for any magnetite project, over the yield used in our Concept Study.
In addition, the ability to have a mill feed averaging 35% iron
following coarse cobbing, delivers a sizeable reduction in
anticipated operating costs. These metallurgical test work results,
together with the proximity to the infrastructure already in use for 
our Cairn Hill operation, support the potential for an economic
development of the project and IMX remains committed to generating
value from the Mt Woods Magnetite Project, for which we are actively
seeking a partner."

About IMX Resources Limited 
IMX is an Australian based mining and base and precious metals
exploration company, listed on the Australian Securities Exchange and
the Toronto Stock Exchange (ASX:IXR)(TSX:IXR)(TSX:IXR.WT), with
exploration projects located in Australia, Africa and North America. 
In Africa, IMX owns and operates the highly prospective Nachingwea
Exploration Project in south-eastern Tanzania, which includes the
potentially word-class Ntaka Hill Nickel Sulphide project, located
approximately 250km west of the port town of Mtwara. Nachingwea is
highly prospective for nickel and copper sulphide, gold and graphite
mineralisation. The Ntaka Hill Nickel Sulphide Project is one of the
world's best un-developed nickel sulphide projects and has the
potential to produce a very clean, high quality premium nickel
concentrate. 
In Australia, IMX operates and owns 51% of the Cairn Hill Mining
Operation, located 55 kilometres south-east of Coober Pedy in South
Australia, where it produces a premium coarse-grained
magnetite-copper-gold DSO product at a rate of 1.8Mtpa.  
IMX is actively developing the Mt Woods Magnetite Project on the
highly prospective Mt Woods Inlier in South Australia. IMX currently
has a JORC Inferred Resource of 569Mt @ 27% Fe at the Snaefell
Magnetite Deposit and a Global Exploration Target of between
200-380Mt @ 25-35% Fe elsewhere in the project. Studies indicate that
coarse grained concentrates that could be produced at Snaefell which
has the potential to attract a significant price premium. 
IMX has a joint venture with OZ Minerals Limited ('Oz Minerals'), the
Mt Woods Copper-Gold JV Project, to explore the Mt Woods tenements
for copper and gold. OZ Minerals is spending a minimum of $20M for a
51% interest in the non-iron rights, with IMX retaining a 49%
interest in the non-iron rights and 100% of the iron ore rights.  
IMX owns 25.65% of Uranex (ASX:UNX), which is a dedicated uranium
exploration company, which is developing the Mkuju Uranium project in
southern Tanzania.

Appendix 1. Summary of test work and results on Snaefell core 
Test work on recent samples of Snaefell core was carried out in two
stages: 


 
--  Spatially representative core samples were crushed to minus 5mm and
    processed using dry magnetic separation (see "Coarse Dry LIMS work"
    below) to produce a magnetic product and a non-magnetic reject. 
--  The magnetic products were composited and used in a Davis Tube Test
    program (see "Davis Tube Test Work" below) to evaluate the product
    quality versus grind size achievable from the ore.
 
 
Coarse Dry LIMS work
 
--  Core samples were crushed to below 5mm. 
--  Crushed feed was processed using a dry low intensity magnetic separator
    at a magnetic field strength of 1100 Gauss. 
--  Average mass yield to the magnetic product was 69% (range from 59% to
    82%). 
--  Average Fe grade in magnetic product was 35.0% (compared to 27.3% in the
    ore).

 
The results for the samples from six drill holes can be summarised as
follows:

Davis Tube Test Work: Grind size versus product quality 
A composite was prepared from the magnetic product recovered using
the dry magnetic LIMS. Samples were processed to target grind sizes
and then processed using a Davis tube. The magnetic concentrate was
recovered and submitted for assay. The results are summarised below
