IMX Resources Limited (ASX:IXR)(TSX:IXR)(TSX:IXR.WT) (‘IMX‘ or the ‘Company‘) reports assay results of five drill holes at the Ntaka Hill Nickel Sulphide Project. Exploration of the Nachingwea Project which includes pursuing a new exploration focus on high-grade nickel mineralisation at the Ntaka Hill Nickel Sulphide Project is the subject of a five year US$60 million earn-in and joint venture agreement with MMG Exploration Holdings Limited (‘MMG‘). Under the terms of the agreement, MMG acts as manager of the joint venture.
Acting Managing Director John Nitschke commented, “These results demonstrate that the Sleeping Giant and Zeppelin deposits are connected and form part of a system of mineralisation which extends from the western edge of the Sleeping Giant deposit towards the P Zone deposit to the east. This system is approximately 1,300 metres wide and remains open to the north, south, east and at depth. Every hole drilled has intersected disseminated nickel mineralisation over significant widths and we expect that this will significantly add to the existing resource.
The presence of the massive sulphide intersections within these results is encouraging given the new focus of exploration for high-grade nickel mineralisation by MMG.”
Three dimensional modelling of the Sleeping Giant and Zeppelin deposits incorporating the work done over the 2013 wet season which included the interpretation of the gravity survey, re-logging and structural interpretation of drill core and compilation and analysis of the data base of soil samples indicated continuity of mineralisation between these two deposits and potentially further to the east at the P Zone deposit. This drilling was carried out to test this model outside of the current resources. The extent of the gravity image shown in Figure 1 is thought to indicate potential for an even bigger footprint for the mineralisation.
The assays from this drilling indicate consistently high nickel tenor similar to the Sleeping Giant and Zeppelin deposits which have been shown to exhibit excellent metallurgical performance and allow for production of a high-grade nickel concentrate. The Company’s 2013 drilling program has involved further drilling at the Sleeping Giant, Zeppelin and P Zone deposits, the results of which are expected to be available in the coming weeks.

About IMX Resources Limited
IMX Resources Limited is an Australian based mining and base and precious metals exploration company, listed on the Australian Securities Exchange and Toronto Stock Exchange (‘TSX‘), with projects located in Australia, Africa and North America.
In Africa, IMX owns 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 undeveloped nickel sulphide projects and has the potential to produce a clean, high quality premium nickel concentrate. IMX has formed an exploration JV with MMG Exploration Holdings Limited to fund further exploration of this Project whereby MMG can contribute up to US$60 million to earn a 60% interest in the Project.
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 Mineral Resource of 569Mt @ 27% Fe at the Snaefell Magnetite Deposit2 and a Global Exploration Target of between 900Mt-1,200Mt @ 18-32% Fe elsewhere in the project. Studies indicate that coarse grained concentrates that could be produced at Snaefell, have the potential to attract a significant price premium. The Global Exploration Target tonnage quantity and grades estimates are conceptual in nature only. These figures are not a Mineral Resource estimate as defined by the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves or NI 43-101, as insufficient exploration has been conducted to define a Mineral Resource and it is uncertain if further exploration will result in the target being delineated as a Mineral Resource.
IMX confirms that the Inferred Mineral Resource at Snaefell was prepared and first disclosed under the JORC Code 2004. It has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported. IMX further confirms that since announcing the Inferred Mineral Resource at Snaefell, it is not aware of any new information or data that materially affects the information included in that announcement and that all material assumptions and technical parameters underpinning the estimates in that announcement continue to apply and have not materially changed.
The Company’s Mt Woods tenements cover almost half of the Mt Woods Inlier which is part of the greater Gawler Craton in South Australia, an area notable for its IOCG deposits where one of the world’s largest copper-gold mines is located at Olympic Dam and an area which is host to three producing copper-gold mines based on IOCG deposits.

|Appendix 1: Summary of Assay Results|
|Drill holes NAD13-368, NAD13-370, NAD13-371, NAD13-373, NAD13-374|
|Nachingwea Project, Tanzania|
|Appendix 2: JORC 2012 Table 1 Reporting|
|Section 1 Sampling Techniques and Data|
|Sampling techniques||– HQ/NQ Diamond core is geologically logged and sampled to geological contacts with nominal samples lengths between 0.25 and 1.5 metres. Core selected for assay is half cored by diamond blade rock saw, numbered and bagged before dispatch to the laboratory for analysis.
– Core is routinely photographed.
|Drilling techniques||– Diamond drilling (HQ/NQ) with standard inner tubes. HQ diameter (63.5mm) typically to competent rock depth and NQ diameter (47.6mm) to target depth.|
|Drill sample recovery||– Diamond core recoveries in fresh rock are measured in the core trays and recorded as RQD metres and RQD% recovery as part of the geological logging process.
– 99% of unweathered core sample intervals in fresh rock measured had core recoveries of 50% or better, 95% of unweathered core sample intervals measured in fresh rock had core recoveries of 80% or better, and 91% of unweathered core sample intervals measured in fresh rock had core recoveries of 90% or better.
|Logging||– All diamond core has been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation.
– Total length of logged data is 2,370.4 metres of 2,370.4 metres drilled for holes NAD13- 368, NAD13-370, NAD13-371, NAD13-373 and NASD13-374.
|Sub-sampling techniques and sample preparation||– Core is cut with a diamond saw into half core. Generally, one of each of the 2 control samples (blank or standard) is inserted into the sample stream every twentieth sample.|
|Quality of assay data and laboratory tests||– Ni, Cu & Co assays are determined by peroxide fusion preparation and ICP-AES finish (ME-ICP61). Laboratory and assay procedures are appropriate for Mineral Resource estimation.
– Laboratory QAQC consisted of standards, blanks and laboratory duplicates (both coarse and pulp) used at a ratio of 1 in 20. The QAQC sample results showed acceptable levels of accuracy and precision.
– The Ntaka Hill assay data is considered suitable for Mineral Resource estimation.
|Verification of sampling and assaying||– Independent verification has not been undertaken on these results, independent review will take place during resource modelling.|
|Verification of sampling and assaying (cont.)||– Below detection limit values (negatives) have been replaced by background values for each element.|
|Location of data points||– Drill holes have been surveyed utilising a Trimble R7 DGPS unit.
– Down-hole surveys were undertaken using a Reflex EZTRAK, a magnetic based multi shot survey instrument with a reading taken approximately every 30 metres down the hole.
– Grid system is UTM WGS84 Zone 37 South datum and projection.
|Data spacing and distribution||– Data spacing is variable being in the range of 100m x 100m to 50m x 50m.|
|Orientation of data in relation to geological structure||– Drill hole sections are orientated east-west orthogonal to the interpreted strike of the deposit.
– The dip orientation of the drill holes are moderate to steep ranging from -60 to -70 (Angled holes have been orientated in both directions east & west). The mineralisation being targeted is flat lying to steeply dipping west. The drilling orientation is adequate for a non-biased assessment of the deposit with respect to interpreted structures and interpreted controls on mineralisation.
|Sample security||– Labelling and submission of samples complies with industry standard.|
|Audits or reviews||– No Audits have been conducted on this data.|
|Section 2 Reporting of Exploration Results|
|Mineral tenement and land tenure status||– The exploration results reported in this announcement are from work carried out on granted prospecting licence number PL4422/2007, owned 100% by IMX.
– The prospecting licence number PL4422/2007 is in good standing.
|Exploration done by other parties||– Exploration has been performed by an incorporated subsidiary company Ngwena Limited.|
|Geology||– The nickel/copper mineralisation at Ntaka Hill occurs entirely within the Ntaka ultramafic intrusion which cross-cuts the late Proterozoic Mozambique mobile belt (MB) lithologies consisting of mafic to felsic gneisses interlayered with amphibolites and metasedimentary rocks. The Ntaka ultramafic package is interpreted to be a Proterozoic MgO-rich intrusion formed at a continental margin. Structure doesn’t appear to be the predominant overall control on mineralisation. The mineralisation identified to date occurs in disseminated and massive nickel sulphide forms.|
|Drill hole Information||– Easting, northing and RL of the drill hole collars are in UTM WGS84 Zone 37 South datum and projection.
– Dip is the inclination of the hole from the horizontal. For example a vertically down drilled hole from the surface is -90°. Azimuth is reported in degrees as the grid direction toward which the hole is drilled.
– Down-hole length of the hole is the distance from the surface to the end of the hole, as measured along the drill trace. Intersection depth is the distance down the hole as measured along the drill trace. Intersection width is the down-hole distance of an intersection as measured along the drill trace.
– Drill hole length is the distance from the surface to the end of the hole, as measured along the drill trace.
|Data aggregation methods||– No high grade cuts have been applied to assay results. Drill core intersection results are distance weighted to their matching assay results using the down-hole width of the relevant assay interval.
– The assay intervals are reported as down-hole length as the true width variable is not known.
– Intersections are reported above 0.20% Ni grade as highlighted in the tables and can contain up to 2m of low-grade or barren material.
– Assays are rounded to 2 decimal places.
– No metal equivalent reporting is used or applied.
|Relationship between mineralisation widths and intercept lengths||– The intersection width is measured down the hole trace and may not be the true width.
– All drill results are down-hole intervals only due to the variable orientation of the mineralisation.
|Diagrams||– Diagrams of drill hole collar locations and the location of zones of mineralisation are included in this announcement.
– A cross section diagram showing highlight intersections in relation to the optimised pit shell are included in this announcement.
|Balanced reporting||– Assay results are presented in Appendix 1.|
|Other substantive exploration data||– No other exploration data is considered meaningful and material to this announcement.|
|Further work||– Future exploration may involve the drilling of more drill holes, both diamond core and reverse circulation, to further extend the mineralised zones and to collect additional detailed data on known mineralized zones.|
