IMX Reports Initial Drilling Results from Ntaka Hill

PERTH, AUSTRALIA--(Marketwired - Sept. 12, 2013) -


  • Drilling at the northern end of the Ntaka Hill intrusive recommenced in May 2013

  • Targeted proposed near surface mineralization extensions in the vicinity of G and J Zones

  • Significant low grade disseminated mineralization intersected in the majority of the holes

  • Best results included from hole NAD13-357:

    • 0.25 metres from 46.75m @ 2.00% nickel

    • 0.35 metres from 49.3m @ 2.39% nickel

IMX Resources Limited (TSX:IXR)(TSX:IXR.WT)(ASX:IXR) ('IMX' or the 'Company') is pleased to report the first round of assay results from its 2013 drilling program at the Ntaka Hill Nickel Sulphide Project (the 'Ntaka Hill Project') in south eastern Tanzania.

The holes drilled in May and June 2013 were targeted on testing the extent of proposed extensions to the mineralisation to the north, south and west of the strongly mineralised G and J Zones at the north-east extremity of the Ntaka Hill intrusion. All holes were targeted based on coincident soil anomalism, down hole electromagnetic ('DHEM') targets and high gravity measurements.

Managing Director Neil Meadows commented, "The intent of the initial phase of our drilling campaign for 2013 was to test the northern extent of the Ntaka Hill intrusion. The results suggest that we have now defined the northern extent of the higher grade mineralisation. Drill results from NAD13-353 in particular are encouraging as they indicate the potential to link G and J Zones. However, given the overall quality of the mineralisation intercepted in the initial drilling program, the decision has been made to focus the next phase of our drilling campaign at Ntaka Hill to the south, where we have previously achieved the most encouraging results in and around Sleeping Giant. There may be more mineralisation along the northern extent of the Ntaka Hill intrusion, but if so it is likely to be much deeper than we have drilled to date."

Figure 1 outlines the drill hole collar positioning with respect to G and J Zones, while Figure 2 outlines the location of G and J Zones with respect to Ntaka Hill as a whole.

Nickel and copper mineralisation was found in all except two of the holes drilled at these locations as detailed in Appendix 1, with a summary of the significant intersections being:

  • Hole NAD13-351: 4 metres from 88m @ 0.53% nickel and 0.19% copper

  • Hole NAD13-352: 10.2 metres from 167m @ 0.48% nickel and 0.15% copper

  • Hole NAD13-353: 1.2 metres from 153m @ 1.12% nickel

  • Hole NAD13-354: 21.4 metres from 139m @ 0.40% nickel including 0.6 metres @ 1.47% nickel and 0.11% copper

  • Hole NAD13-357: 0.25 metres from 46.75m @ 2.00% nickel, 0.12% copper and 0.35 metres from 49.3m @ 2.39% nickel and 0.46% copper

  • Hole NAD13-360: 16 metres from 54m @ 0.29% nickel and 0.08% copper

  • Hole NAD13-362: 1 metre from 243m @ 0.83% nickel and 0.25% copper

  • Hole NAD13-364: 10 metres from 55m @ 0.37% nickel and 0.09% copper

Drilling has extended our knowledge of the high-grade mineralisation to the south of J Zone, and our belief is that this high-grade mineralisation may extend further at depths beyond current drilling. Disseminated mineralisation remains open to the south and north of G and J Zones.

NAD13-353 has provided encouraging results with shallow mineralisation being discovered in the area between the two known deposits (G and J Zones) offering potential for these two zones to be joined together by infill drilling. This is supported by results from 2012 which returned high-grade mineralisation between G and J Zones. Further drilling will however be required to definitively establish this.

Targeting in the north has been complicated due to the presence of large amounts of graphite which provides false targets in DHEM measurements and surface induced polarisation techniques. Drilling in the north will be reconsidered later in the season as this location is better suited for the wet season between December and April.

Drilling is currently focusing on the south of the Ntaka intrusion as this offers the opportunity to significantly increase resources in the immediate future. Results from the work completed to date in that area will be available for release 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 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 undeveloped 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 Mineral Resource of 569Mt @ 27% Fe at the Snaefell Magnetite Deposit and a Global Exploration Target of between 900Mt-1,200Mt @ 20-32% 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 2004 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 has a joint venture with OZ Minerals Limited ('OZ Minerals'), the Mt Woods Copper-Gold Joint Venture Project, to explore the Mt Woods tenements for copper and gold. OZ Minerals is spending a minimum of AUD 20 million 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.

Section 1 Sampling Techniques and Data

Criteria Explanation
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.
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 53,795 metre of a total 54,754 metre drilled. Please recheck these values.
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

Criteria Explanation
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 granulites, gneisses and migmatites 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 appears 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 0.2% and 0.3% 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 G and J Zones 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.
