ASX RELEASE
Western Gawler Craton Project Update
HIGHLIGHTS
High-resolution aeromagnetic survey completed
New high quality data showing significant increase in resolution from current magnetic data
New data highlighting areas of interest for magmatic Ni-Cu style mineralisation
Major drilling program planned for mid-2015
Monax Mining Ltd (ASX:MOX) is pleased to announce that a detailed aeromagnetic survey has been completed on its Western Gawler Craton ("WGC") Project (see Figure 1), wholly funded by Western Areas Limited ("Western Areas") (ASX:WSA) under the recently announced Farm-In Agreement (see ASX Release 9 October 2014).
The survey comprised 100m spaced flight lines over the entire project area and was completed in approximately six weeks. The new data provides a high-quality dataset suitable for outlining areas of favourable lithology and structural setting to host massive polymetallic mineralisation.
Figure 2 shows a reduced to pole (RTP1) image with the previously available data shown in the background. Figure 3 provides a comparison between the older data and the newly acquired magnetic data showing the significant increase in detail for the newly acquired data.
Interpretation of the data has commenced and Western Areas are planning a major drilling program to commence in the coming months once the required statutory access approvals are received.
The western Gawler Craton is interpreted to have a geological history analogous to the Thompson Nickel Belt in Canada and the Albany-Fraser Belt in Western Australia. The western Gawler Craton is considered a highly prospective and under-explored part of South Australia and Monax has acquired a strategic landholding within this potential new mineral province.
The Nova-Bollinger Deposit in the Albany-Fraser Belt in Western Australia is located within a prominent magnetic and gravity ridge. Two prominent magnetic and gravity ridges are located within Monax's WGC Project area, representing prime targets for potential magmatic nickel- copper mineralisation similar to that at Nova-Bollinger.

The Tropicana gold deposit is located along the margin of the Albany Fraser Belt and exploration will also be focussed on testing the potential for a similar style of mineralisation within the WGC Project area.
"Monax is excited by the new aeromagnetic data and is looking forward to reviewing and interpreting the data with our partner Western Areas," Monax Mining Managing Director, Mr Gary Ferris, said today.
"The new data is a significant step forward for the project because the prospective basement rocks are obscured by a thin veneer of recent sediments and this data will allow a systematic approach to interpreting the data and planning the upcoming drilling program " he said.
"We are excited to have such a proactive partner in Western Areas who have completed this major survey within three months of signing the Farm-In agreement" he said.

Sampling techniques
|
|
Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate
to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should
not be taken as limiting the broad meaning of sampling.
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
Aspects of the determination of mineralisation that are Material to the
Public Report.
In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge
for fire assay'). In other cases more explanation may be required,
such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

Criteria
JORC Code explanation Commentary
Mineral tenement and land tenure status
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
The survey was undertaken on Exploration Licences 5077, 5199 and
5200 which are owned 100% by Monax Mining Limited. These 3 tenements are part of a farm-in agreement with Western Areas Limited. The tenements are partly located in Aboriginal Lands Trust (ALT), Yellabinna Regional Reserve and freehold land. The area outside of the ALT area is part of the Far West Native Title determination.
There are no known impediments to obtain a licence to operate in the area. Monax and Western Areas have commenced negotiations with the Aboriginal Lands Trust and the Far West Native Title Group.
Exploration done by other parties
Acknowledgment and appraisal of exploration by other parties. Several companies have explored for coal, mineral sands and nickel in the area. Monax has reviewed this exploration data and no systematic approach in the search for Ni-Cu has been undertaken.
Geology Deposit type, geological setting and style of mineralisation. Intrusive Ni-Cu style mineralisation.
Drill hole
Information
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
o easting and northing of the drill hole collar
o elevation or RL (Reduced Level - elevation above sea level in
metres) of the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
If the exclusion of this information is justified on the basis that the
information is not Material and this exclusion does not detract from
the understanding of the report, the Competent Person should clearly explain why this is the case.
