Rox Resources Limited ( ASX: RXL ) (“ Rox ” or “ the Company ”) is pleased to advise further drill results from its Camelwood nickel sulphide prospect at Fisher East, located 450km north of Kalgoorlie in Western Australia (Figure 1).
Geological Model
Continued drilling has allowed interpretation of the geological setting as that of a typical komatiite-hosted (Kambalda type) nickel sulphide deposit.
All of the nickel sulphide mineralisation occurs at or near to the “basal contact” of an intensely talc-carbonate altered, high-magnesium ultramafic rock (komatiite lava flow) with the stratigraphic footwall felsic sediment. Stratigraphically above the high-magnesium komatiite flow is a sequence of lower magnesium komatiite flows overlain by a sequence of mafic rocks (lavas and possible intrusive sills).
The mineralised zone itself is zoned, with a stratigraphically lowermost massive sulphide zone overlain by a semi-massive (matrix) sulphide zone and then an uppermost disseminated sulphide zone, hosted within the intensely talc-carbonate altered highmagnesium ultramafic rocks. Due to faulting and other structural complications not all of these mineralised zones are present in all holes.
The evolving understanding of the geological setting of the deposit will greatly assist in planning and optimising ongoing drill programs.
Drilling to date at Camelwood has been undertaken with two main aims:
-
To define the lateral extent of mineralisation (along strike) and to characterise the mineralisation at depth.
-
To define lenses/pods of thicker, higher grade mineralisation.
That approach has been highly successful with an 800m strike length defined and mineralisation drilled down to approximately 400m below surface on selected sections. Of

ROX RESOURCES LIMITED – ASX RELEASE 29 April 2013
the 42 holes drilled to date (18 diamond core and 24 RC) only 4 have not intersected significant nickel mineralisation. The limits of the mineralised system have yet to be defined both along strike and at depth. This is clearly an extensive and continuous mineralised system.
The drilling to define thicker higher grade mineralisation has also been successful where two broad areas of mineralisation have now become apparent at Camelwood, termed the Main Zone and the Northern Zone (Figures 2 & 3).
Recent drilling has concentrated on the Northern Zone where a potentially thicker higher grade zone of mineralisation is present. It is defined by such holes as MFEC010 (18m @ 1.53% Ni), MFEC021 (19m @ 1.3% Ni) and new hole MFED014: 7.4m @ 1.9% Ni , including 1.45m @ 3.6% Ni from 130.6m (see Figures 2 & 3 and Table 1).
The Main Zone is defined by holes such as MFED001 (11.4m @ 2.9% Ni), MFED002 (16.3m @ 1.8% Ni), MFED005 (5.7m @ 2.25% Ni), MFED008 (1.8m @ 2.8% Ni) and MFED010 (6.15m @ 3.3% Ni). This mineralisation forms a zone that is interpreted to plunge north (Figures 3 & 4) and is still open at depth. Already it has the dimensions to be a potentially economic zone of mineralisation.
Recent Results
Main Zone
Diamond Drilling
Assays from diamond holes MFED011 and 012 (refer to Figures 2 & 3) have been received, and results above a 1% Ni cut-off are:
MFED011: 0.27m @ 1.9% Ni from 293.71m
MFED012: 0.74m @ 3.8% Ni from 375.68m
These holes, some 250m apart and both still strongly mineralised, fit with the company’s interpreted model and may define the upper and lower limits of the thicker higher grade zone so far defined in the limited portion of the Main Zone drilled to date (Figures 3 & 4). The mineralisation in hole MFED012 was truncated by a fault while still in massive sulphide mineralisation, so the full sulphide section (massive - semi massive – disseminated) was not represented.
RC Drilling
Assays from RC holes MFEC022 and 024 (see Figures 2 & 3) have been received, and results above a 1% Ni cut-off are:
MFEC022: 1m @ 2.6% Ni from 186m
MFEC024: 4m @ 1.3% Ni from 144m, and 4m @ 1.0% Ni from 155m
These results continue to define the prospective horizon, but were aimed at or above the top of the main EM conductive zone (Figures 3 & 4). Hole MFEC024 probably defines the top edge of the Main Zone; along with other RC holes such as MFEC004 (20m @ 1.06% Ni), MFEC003 (5m @ 1.45% Ni and 3m @ 1.72% Ni) and MFEC020 (5m @ 1.8% Ni and 2m @ 1.5% Ni).

ROX RESOURCES LIMITED – ASX RELEASE 29 April 2013
Northern Zone
Diamond Drilling
Assays from diamond holes MFED013 and 014 (refer to Figures 2 & 3) have been received, and results above a 1% Ni cut-off are:
MFED013: 0.68m @ 5.9% Ni from 140.87m
MFED014: 7.4m @ 1.9% Ni , including 1.45m @ 3.6% Ni from 130.6m
These holes were drilled between RC holes MFEC010 and 021 described above, and indicate a wider zone of mineralisation within an extensive area of narrow shallow high-grade mineralisation.
RC Drilling
Assays from RC hole MFEC023 (see Figures 2 & 3) have been received:
MFEC023: 19m @ 0.44% Ni (lightly disseminated zone) from 101m
This hole continues to geochemically define the prospective horizon in the Northern Zone, and further drilling along strike to the north is planned.
Camelwood North
Testing of the deeper Camelwood North EM conductor located approximately 500m north of Camelwood on section 7036700N was completed recently as diamond hole MFED017. Assays are pending.
Drilled as a “wildcat exploration hole”, it intersected a number of strong sulphidic zones (pyrite and pyrrhotite) however nickel sulphides were not present. The zones of pyrite and pyrrhotite occur at geological contacts that could be stratigraphically favourable for development of nickel sulphides along strike or down dip. Downhole EM surveys in this hole are planned in the near future.
Looking Forward
Diamond drilling is continuing at Camelwood. New holes recently drilled are shown on Figures 2 & 3.
The drilling rig has now moved back to the Main Zone and is drilling on section 7036000N (viz. holes MFED018 and 019) down plunge of the high grade and thicker intersections in holes MFED010 and 001.
Further diamond drilling will now focus on extending and defining the thicker and higher grade zone in the Main Zone that is interpreted to be plunging north from holes MFED002 through MFED001 and MFED010 (Figures 3 & 4).
In addition, step back drilling on the newly granted Exploration Licence E53/1716 to test the southern and deeper portions of the Main Camelwood EM conductor is now able to commence as the heritage survey has been completed and the Program of Works (PoW) has been approved by the WA Department of Mines and Petroleum.

ROX RESOURCES LIMITED – ASX RELEASE 29 April 2013
After a recent three week break RC drilling will re-commence shortly to test for further strike extensions to the north and south of currently identified mineralisation .
Downhole EM surveys are planned in diamond holes MFED016, 017, 018 and 019.

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)
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 a strong potential for nickel. 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] .
Initial drilling by Rox has defined numerous high-grade targets and defined a Measured, Indicated and Inferred Mineral Resource of 973,000 tonnes grading 2.75 g/t gold to be defined 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).
Drilling at the Camelwood nickel prospect has intersected semi-massive to massive and disseminated nickel sulphide mineralisation in a number of holes along an 800m strike length and up to 350m depth, including 11.4m @ 2.9% Ni and 6.15m @ 3.3% Ni , with the mineralisation open in all directions.
Reward Zinc-Lead Project (Farm-out Agreement)
Rox has signed an Earn-In and Joint Venture Agreement with Teck Australia Pty Ltd. (“Teck”) to explore its 670km[2] Myrtle/Reward zinc-lead tenements, located 700km south-east of Darwin, Northern Territory. The Myrtle deposit has a current Inferred Mineral Resource of 43.6 Mt @ 5.04% Zn+Pb (Indicated: 5.8 Mt @ 3.56% Zn, 0.90% Pb; Inferred: 37.8 Mt @ 4.17% Zn, 0.95% Pb). Historic drill intercepts of sediment-hosted mineralisation exist at the Teena prospect, including 11.3m @ 10.9% Zn+Pb and 8.6m @ 9.84% Zn+Pb . Under the terms of the agreement, Teck are required to spend A$5m by 31 August 2014 to earn an initial 51% interest. Teck can increase its interest in the project to 70% by spending an additional A$10m (A$15m in total) over an additional 4 years.
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 by spending $500,000 within the first two years. Rox can 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.
Marqua Phosphate Project (100%)
Rox owns four tenements covering approximately 1,900 km[2] in the Northern Territory which comprise the Marqua Phosphate project. The project has the potential for a sizeable phosphate resource to be present, with surface sampling returning values up to 39.4% P2O5 and drilling (including 6m @ 19.9% P2O5 and 5m @ 23.7% P2O5) confirming a 30km strike length of phosphate bearing rocks. In addition to phosphate, there is also potential for lead-zinc mineralisation. The project is located 300km southwest of Mt Isa, and is situated 250km from the nearest railhead and gas pipeline at Phosphate Hill.
