Mineralised zone now drilled to 300m below surface and still open to the north, south and at depth
Rox Resources Limited ( ASX: RXL ) (“ Rox ” or “ the Company ”) is pleased to report further solid drilling results from its diamond drilling program currently underway at the Musket nickel sulphide prospect near Mt Fisher, 500km north of Kalgoorlie, Western Australia.
Rox Managing Director, Mr Ian Mulholland said, “The latest results from Musket confirm that we have identified a coherent body of nickel sulphide mineralisation down to 300m depth that we haven’t closed off yet. True widths in some holes are over 10m thick and have grades of 2.0% Ni or better. These results augur well for the estimation of a significant maiden resource later this year.”
The suite of results from Musket to date is impressive, and includes these new results:
9.0m @ 1.9% Ni from 268.0m in hole MFED045

As well as previously announced RC and diamond drilling results, such as:
17m @ 2.2% Ni , including
4m @ 3.2% Ni from 214m in hole MFEC059
14m @ 1.5% Ni from 191m in hole MFEC064
17m @ 2.2% Ni , including
2m @ 8.1% Ni from 227m in hole MFEC065
15.0m @ 2.7% Ni , including
0.9m @ 19.5% Ni from 264.7m in hole MFED042
16.2m @ 2.8% Ni , including
0.8m @ 19.0% Ni from 305.1m in hole MFED043, and
15.9m @ 2.1% Ni from 248.0m, including
10.2m @ 2.6% Ni from 252.2m in hole MFED044
Downhole EM surveying is being conducted in holes MFED047, 049 and 050. EM surveying has proved to be a valuable targeting tool and the results of this survey will be used in assist in future drill hole locations.
“The mineralisation we are delineating at Musket is much thicker than the 1.6Mt at 2.2% Ni (ASX:RXL 3 October 2013) Camelwood deposit 2km to the north. While Camelwood is a very good deposit, Musket is shaping up to add significant new tonnes to our overall project resource.”
“In particular, the massive sulphide zone at Musket consistently shows grades between 13% and 19% Ni, and the matrix and disseminated zones are generally 1.5% to 3.5% Ni. We’re starting to build a solid resource base now, and that bodes well for future project development” Mr Mulholland said.
Diamond drilling is ongoing, with further results anticipated over the coming weeks.

About Rox Resources
Rox Resources Limited is an emerging Australian minerals exploration company. The company has four key assets at various levels of development with exposure to gold, nickel, zinc, lead, copper and phosphate, including the Mt Fisher Gold Project (WA), Myrtle/Reward Zinc-Lead Project (NT), the Bonya Copper Project (NT) and the Marqua Phosphate Project (NT).
Mt Fisher Gold-Nickel Project (100% + Option to Purchase $3.6 million)
The Mt Fisher gold project is located in the highly prospective North Eastern Goldfields region of Western Australia and in addition to being well endowed with gold the project hosts strong nickel potential. The total project area is 655km[2] , consisting of a 485km[2] area 100% owned by Rox and an Option to purchase 100% of a further 170km[2] .
Recent drilling at the Camelwood nickel prospect has defined a JORC 2012 Mineral Resource (ASX:RXL 3 October 2013) of 1.6Mt grading 2.2% nickel reported at 1.0% Ni cut-off (Indicated Mineral Resource: 0.6Mt grading 2.4% Ni, Inferred Mineral Resource: 1.0Mt grading 2.1% Ni) comprising massive and disseminated nickel sulphide mineralisation, and containing 34,600 tonnes of nickel. A higher grade core of 520,000 tonnes grading 3.1% nickel reported at a 2.5% Ni cut-off (Indicated Mineral Resource: 240,000 tonnes grading 3.2% Ni, Inferred Mineral Resource: 280,000 tonnes grading 3.0% Ni) is present. The mineralisation is still open in all directions. The nickel Mineral Resource occurs partly on tenements under Option to Purchase to Rox, with an exercise price payable as follows: $1.1 million by 30 June 2014, $0.2 million by 31 December 2014, and $2.3 million by 30 June 2015.
Drilling by Rox has also defined numerous high-grade gold targets and a JORC 2004 Measured, Indicated and Inferred Mineral Resource (ASX:RXL 10 February 2012) of 973,000 tonnes grading 2.75 g/t gold reported at a 0.8 g/tAu cut-off exists for 86,000 ounces of gold (Measured: 171,900 tonnes grading 4.11 g/t Au, Indicated: 204,900 tonnes grading 2.82 g/t Au, Inferred: 596,200 tonnes grading 2.34 g/t Au) aggregated over the Damsel, Moray Reef and Mt Fisher deposits.
Reward Zinc-Lead Project (49% + Farm-out Agreement)
Rox has signed an Earn-In and Joint Venture Agreement with Teck Australia Pty Ltd. (“Teck”) to explore its highly prospective 670km[2] Myrtle/Reward zinc-lead tenements, located 700km south-east of Darwin, Northern Territory, adjacent to the McArthur River zinc-lead mine.
The Myrtle zinc-lead deposit has a current JORC 2004 Mineral Resource (ASX:RXL 15 March 2010) of 43.6 Mt @ 5.04% Zn+Pb reported at a 3.0% Zn+Pb cut-off (Indicated: 5.8 Mt @ 3.56% Zn, 0.90% Pb; Inferred: 37.8 Mt @ 4.17% Zn, 0.95% Pb).
Recent drilling at the Teena zinc-lead prospect intersected 26.4m @ 13.3% Zn+Pb including 16.2m @ 17.2% Zn+Pb, and 20.1m @ 15.0% Zn+Pb including 12.5m @19.5% Zn+Pb , and together with historic drilling has defined significant high grade zinc-lead mineralisation over a strike length of at least 1.5km.
Under the terms of the Agreement, Teck has now met the expenditure requirement for a 51% interest, with Rox holding the remaining 49%. Teck has elected to increase its interest in the project to 70% by spending an additional A$10m (A$15m in total) by 31 August 2018 (ASX:RXL 21 August 2013).
Bonya Copper Project (Farm-in Agreement to earn up to 70%)
In October 2012 Rox signed a Farm-in Agreement with Arafura Resources Limited to explore the Bonya Copper Project located 350km east of Alice Springs, Northern Territory. Outcrops of visible copper grading up to 34% Cu and 27 g/t Ag are present. Under the Agreement Rox can earn a 51% interest in the copper, lead, zinc, silver, gold, bismuth and PGE mineral rights at Bonya by spending $500,000 within the first two years. Rox can then elect to earn a further 19% (for 70% in total) by spending a further $1 million over a further two years. Once Rox has earned either a 51% or 70% interest it can form a joint venture with Arafura to further explore and develop the area.

Appendix
The following information is provided to comply with the JORC (2012) requirements for the reporting of the Musket diamond drilling results on tenement E53/1318.
Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation Commentary |
|---|---|
| Sampling techniques | Nature and quality of sampling (e.g. 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. RC hole diameter was 5.5" (140 mm) reverse circulation percussion (RC). Sampling of RC holes was undertaken by collecting 1m cone split samples at intervals. Diamond drill hole core size is NQ2 size diameter through the mineralisation. Sampling of diamond holes was by cut half core as described further below. Drill holes were generally angled at -600towards grid west (but see Table for individual hole dips and azimuths) to intersect geology as close to perpendicular as possible. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Drillhole locations were picked up by handheld GPS. Logging of drill samples included lithology, weathering, texture, moisture and contamination (as applicable). Sampling protocols and QAQC are as per industry best practice procedures. |
|
| 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information Diamond core is dominantly NQ2 size, sampled on geological intervals, with a minimum of 0.1 m up to a maximum of 1.5 m. NQ2 core is cut into half, or quarter for HQ holes. RC drillholes were sampled on 1m intervals using riffle or cone splitter units. Samples were sent to Intertek Genalysis in Kalgoorlie, crushed to 10mm, dried and pulverised (total prep) in LM5 units (Some samples > 3kg were split) to produce a sub-sample. The pulps were then sent to Perth for analysis by four acid digest with a multi-element ICP-OES finish (code: 4A/OE-multi element). Au, Pt and Pd were analysed by 50 gram fire assay with a mass spectrometer finish. Internal laboratory QA uses CRM's, blanks, splits and replicates, along with 10% repeats. |
|
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). Drilling techniques were Reverse Circulation (RC) and diamond core (DD). The RC hole diameter was 140mm face sampling hammer. Hole depths range from 98m to 258m. DD hole diameter was mostly NQ2 with 5 ¼ inch mud rotary pre-collar and HQ upper hole portions. Hole depths range from 319.4m to 401.8m. The core was orientated using a Camtech orientation tool. |
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed Diamond drill core recoveries were logged and recorded in the database. Overall recoveries were >95%, and there were no significant core loss or recovery problems. RC drill recoveries were high (>90%). |
| Measures taken to maximise sample recovery and ensure representative nature of the samples Diamond core was reconstructed into continuous sample runs on an angle iron used for orientation marking. Depths are measured and checked against marked depths on the core blocks. RC samples were visually checked for recovery, moisture and contamination and notes made in the logs. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Most of the samples used in the Mineral Resource estimate come from diamond core drilling which had high recoveries. There is no observable relationship between recovery and grade, and therefore no sample bias. |

| Criteria | JORC Code explanation Commentary |
|---|---|
| The use of twinned holes. No holes have been twinned at this stage. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Primary data was collected using a standard set of Excel templates on Toughbook laptop computers in the field. These data are transferred to Geobase Pty Ltd for data verification and loading into the database. |
|
| Discuss any adjustment to assay data. No adjustments or calibrations have been made to any assay data. |
|
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Not applicable. A hand held GPS has been used to determine collar locations at this stage. |
| Specification of the grid system used. The grid system is MGA_GDA94, zone 51 for easting, northing and RL. |
|
| Quality and adequacy of topographic control. The topographic surface was generated from digital terrain models generated from low level airborne geophysical surveys. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. The drill hole spacing varies 40-100 metres between drill sections, with some areas at 40 metre drill section spacing. Some sections (but not all) have had more than one hole drilled. Down dip step out distance varies 40-60 metres. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. The mineralisation and geology shows very good continuity from hole to hole and will be sufficient to support the definition of a Mineral Resource or Ore Reserve and the classifications contained in the JORC Code (2012 Edition) in due course. |
|
| Whether sample compositing has been applied. No sample compositing has occurred for diamond core drilling. Sample intervals are based on geological boundaries with even one metre samples between. For RC samples, sample compositing occurred over 4 metre intervals for non-mineralised material, but all mineralised intervals were sampled at a one metre interval. |
|
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. The deposit strikes at about 345 degrees and dips to the east at between -60 to -70 degrees. The drill orientation was planned to be 270 degrees, so slightly oblique to the perpendicular direction, however, some drill holes have swung slightly south (to about 260 degrees) so were drilling essentially perpendicular to strike. This is confirmed in structural logging of mineralised zones. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. No sampling bias is believed to have been introduced. |
|
| Sample security | The measures taken to ensure sample security. Sample security is managed by the Company. After preparation in the field samples are packed into polyweave bags and despatched to the laboratory. For a large number of samples these bags were transported by the Company directly to the assay laboratory. In some cases the sample were delivered to a transport contractor who then delivered the samples to the assay laboratory. The assay laboratory audits the samples on arrival and reports any discrepancies back to the Company. No such discrepancies occurred. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. A review of previous sampling techniques and data was carried out by Optiro as part of the Camelwood Mineral Resource estimate(ASX:RXL 3 October 2013). The database is considered by Optiro to be of sufficient quality to support a Mineral Resource estimate. In addition, from time to time, the Company carries out its own internal data audits. |

Section 2 Reporting of Exploration Results
| 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 mineralisation is located within Exploration License E53/1318. Rox Resources holds an option to purchase E53/1318 (among other tenements) from Gerard Victor Brewer payable in three instalments; $1.1 million payable by 30 June 2014, $0.2 million payable by 31 December 2014, and $2.3 million payable by 30 June 2015. |
| 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 tenement/s is/are in good standing and no known impediments exist. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. No previous exploration for nickel has been done at the Cannonball or Musket prospects. |
| Geology | Deposit type, geological setting and style of mineralisation. The geological setting is of Archaean aged komatiite system, bounded by hangingwall basaltic rocks and footwall felsic metasediments. Mineralisation is mostly situated at the (eastern) basal ultramafic - felsic contact. The rocks are strongly talc-carbonate altered. Metamorphism is mid-upper Greenschist. The deposit is analogous to Kambalda style nickel sulphide deposits. |
| 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: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. Refer to drill results Table/s and the Notes attached thereto. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. All reported assay intervals have been length weighted. No top cuts have been applied. A lower cutoff of 1% is applied with up to 2m of internal dilution allowed. See Notes to Table/s. |
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. High grade massive sulphide intervals internal to broader zones of mineralisation are reported as included intervals. See Table/s. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalent values have been used or reported. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). The mineralisation is moderately east dipping throughout the deposit. Drillhole azimuths were planned at 2700and holes generally inclined at -600west (but see Table 1). Given the angle of the drill holes and the interpreted dip of the host rocks and mineralisation (see Figures 2-4), reported intercepts will be more than true width. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. Refer to Figures and Table in the text. |
