Airborne EM survey produces a number of new conductors for evaluation and testing
-
Anomalies coincident with geological trends
Rox Resources Limited ( ASX: RXL ) (“ Rox ” or “ the Company ”) is pleased to report further promising exploration results from its Fisher East Nickel Project located 500km north of Kalgoorlie in Western Australia.
Rox recently completed an airborne Versatile Time Domain ElectroMagnetic (VTEM) survey along strike and to the south of its Camelwood and Musket nickel sulphide deposits.
ABN: 53 107 202 602
Projects:
Mt Fisher: nickel-gold (100%)
Reward: zinc-lead (49%)
Bonya: copper-silver (earning up to 70%)
Marqua: phosphate (100%)
==> picture [140 x 194] intentionally omitted <==
The survey was very successful, with a number of conductors (Figure 1) identified along the trend of the Fisher East ultramafic unit that hosts several nickel sulphide deposits discovered by Rox over the last two and a half years.
One area about 5km to the south of the new Sabre discovery is particularly interesting with a cluster of five conductors, with other conductors further south than those.
Rox Managing Director, Mr Ian Mulholland said “We are very pleased with the results of this VTEM survey, which was designed to detect accumulations of nickel sulphide mineralisation. We have used this technique very successfully in the past and these new conductors, situated along the trend of the Fisher East ultramafic unit where we have already successfully discovered a number of nickel sulphide deposits, are very encouraging”.
The evaluation of the VTEM survey is continuing with the assistance of the Company’s geophysical consultants, Southern Geoscience, after which a drilling program will be designed for initial testing.

ROX RESOURCES LIMITED - ASX RELEASE 16 June 2015
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 $2.3 million to pay)
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 and Musket nickel prospects has defined a JORC 2012 Mineral Resource (ASX:RXL 9 October 2013 and 4 September 2014) of 3.6Mt grading 2.0% Ni reported at 1.0% Ni cut-off (Indicated Mineral Resource: 1.8Mt grading 2.2% Ni, Inferred Mineral Resource: 1.9Mt grading 1.8% Ni) comprising massive and disseminated nickel sulphide mineralisation, and containing 72,100 tonnes of nickel. Higher grade mineralisation is present in both deposits (refer to ASX announcements above), and is still open at depth beneath each deposit. The nickel Mineral Resource occurs partly on tenements under Option to Purchase to Rox, with the remaining exercise price of $2.3 million payable 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 Au 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).
Drilling at the Teena zinc-lead prospect has 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 1.9km (ASX:RXL 5 August 2013, 26 August 2013, 18 September 2013, 11 October 2013, 27 October 2014, 10 November 2014, 15 December 2014). Teena is the most significant new discovery of zinc in Australia since Century in 1991.
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 (ASX:ARU) 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, with the style of mineralisation similar to the adjacent Jervois copper deposits (see ASX:KGL). EM surveys defined a number of anomalies that could represent sulphide mineralisation at depth (ASX:RXL 5 August 2014). Drill testing has intersected visible copper mineralisation at three prospects, with massive copper sulphides intersected at the Bonya Mine prospect, including 38m @ 4.4% Cu and 11m @ 4.4% Cu (ASX:RXL 20 October 2014, 5 November 2014, 1 December 2014).
Under the Farm-in Agreement Rox earned a 51% interest in the copper, lead, zinc, silver, gold, bismuth and PGE mineral rights at Bonya by spending $500,000 by 10 December 2014 (ASX:RXL 16 December 2014). Rox has elected to earn a further 19% (for 70% in total) by spending a further $1 million by 10 December 2016.

Appendix
The following information is provided to comply with the JORC Code (2012) requirements for the reporting of the geophysical results on tenement E53/1802.
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. An airborne, time-domain electromagnetic survey has been completed. The survey was carried out along E-W trending survey lines spaced 150m apart at an average terrain clearance of 42m. The VTEM system collects time domain electromagnetic data, magnetic data and digital terrain data. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used VTEM airborne system is fully calibrated and daily tests were carried out to ensure data quality. |
|
| 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 This release has no reference to mineralisation. |

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. Rox holds a recently negotiated option to purchase E53/1802 from Gerard Victor Brewer with a yearly payment of $100,000 payable by 30 June each year for the next three years and an exercise price of either $600,000 or $700,000 depending on when the option is exercised. |
| 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 tenure is secure and in good standing at the time of writing. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. No previous detailed exploration for nickel sulphides had been undertaken on the tenements before Rox’s involvement, except for one RC hole drilled by an Independence Group/Cullen Resources JV in 2006 into an EM conductor near the Sabre prospect. That single hole did not intersect any nickel sulphides. |
| 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. This release has no reference to drilling. |
| 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. There is no reference to grade or sampling in this release. |
| 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. There is no reference to grade or sampling in this release. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. There is no reference to grade or sampling in this release. |
|
| 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’). There is no reference to mineralisation intersections or drilling in this release. |
| 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. This release has no reference to mineralisation intercepts or drill holes. |
| Balanced reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. This release has no reference to mineralisation intercepts, assays or grades. |
