Australian resources company TNG Limited (ASX: TNG ) advises that ongoing drilling at its 100%-owned Mount Hardy Copper Project in the Northern Territory ( Figure 1 ) is continuing to deliver positive results, with the third hole in the current 15-hole program intersecting significant zones of copper mineralisation grading up to 4.5% Cu plus gold grades of up to 1.2g/t Au .
This is the first time coincident copper and gold have been recorded in drill samples.
Diamond drilling of six target areas at Mount Hardy commenced in early March (see ASX Release – 11 March 2013). Drilling has been completed on EM Targets 2, and 4, and at the geochemical targets at the Mount Hardy and Browns Prospects, and is continuing at EM Target 1 and both IP targeted holes at Mount Hardy and Browns.
To date, 14 of the 15 planned diamond drill holes have been completed, for a total of 1,800m. Samples have been submitted for the first 12 holes with laboratory results now received for the first three holes, all of which were drilled at the Mount Hardy prospect. Results for holes 13MHDDH001 and 13MHDDH002 were reported in the ASX Release of 18[th] of April 2013.
Results from the third hole, 13MHDDH003, are presented below. A full assessment of the Mount Hardy Prospect and other target areas will follow during the June Quarter once all outstanding assay results have been received. The locations of holes reported are shown in Table 1 and on Figure 2. Significant results for hole 13MHDDH003 are outlined on Table 2.
Three sections were drilled at the Mount Hardy Prospect targeting the strong surface copper mineralisation outlined last year ( see ASX Releases – 18 September 2012 and 21 October 2012 ).
A total of four holes (13MHDDH001 to 13MHDDH004) were drilled on these three sections. All holes have been drilled towards the SSE (azimuth 150 degrees) and 45-60 degrees dip.
Hole 13MHDDH003 has returned a number of intersections of potentially economic mineralisation, as outlined in Table 2 below. The results provide further strong evidence of the substantial potential of the Mount Hardy Project to host a large mineralised system.
Copper grade is associated with quartz veining, both thin (mm to cm scale) stringer stockworks and broader (>1m) veins, found within zones of intense shearing and structural disruption.
All intersections below 45m down-hole are in fresh rock with copper species being predominantly chalcopyrite, and minor bornite and chalcocite between 45m and 58m. Mineralisation occurs from near surface to 97m depth, with the strongest mineralisation occurring between 45m and 74m – a 29m thick zone of alteration and veining.
Alteration is generally silicification with associated sericite-pyrite development. Weathering occurs to a depth of 35 metres and malachite dominates as the copper species at shallow depths.
Best analytical values to date are:
1.60m @ 1.60% Cu from 45.40m, including: 0.60m @ 2.92% Cu from 45.40m 3.10m @ 1.86% Cu from 61.90m, including: 1.00m @ 4.50% Cu from 62.50m
Hole 3MHDDH003 was drilled to test below the surface costeaning completed in the 1960s. Recent re-sampling of these historic costeans by TNG returned results of 12m grading 2% Cu (in semi-continuous channel sampling). This section line lies 80m to the east of the previously reported holes 13MHDDH001 and 13MHDDH002.
Results included a multi-element suite and fire assay gold analyses. Gold results in hole 13MHDDH003 include anomalous values in both higher copper zones, with the significance of this association still to be determined. The copper zones were also sporadiacally anomalous for silver (to 19ppm Ag) and zinc (to 980ppm Zn).
The full suite of results including gold assays is provided below:
- 0.60m @ 2.92% Cu and 1.15g/t Au from 45.40m; and 1.00m @ 4.50% Cu and 0.40g/t Au from 62.50m down-hole
Following an Induced Polarisation (IP) geophysical survey over the Mount Hardy prospect area in March 2013 another hole was planned and has recently been completed. The IP survey outlined a strong chargeability zone which plunges at a shallow angle to the west and which corresponds with the exposed copper mineralisation seen on the Mount Hardy Prospect hill.
This zone has been tested by the shallow holes 13MHDDH001 through 004 (see Figure 3). The IP-targeted hole is shown in magenta on Figure 3. Results for 13MHDD004 are expected soon and will be reported after assessment.
As per the new 2012 JORC reporting guidelines, a summary of the material information used in these exploration results, and outlined in Appendix One, is as follows:
Mineralisation noted to date at the Mount Hardy project is hosted by the Lander Rock Beds Palaeoproterozoic metasediments of the Aileron Province of the Arunta Region, and is found within quartz veins and shear zones together with mineralised and altered Lander schists. Copper is found in chalcopyrite in fresh rock (drill samples, >30 metres below surface) but all surface exposures are oxidised with malachite, azurite, and chrysocolla dominant. Lead and zinc occur as galena and sphalerite in fresh material and cerrusite and smithsonite (respectively) in weathered surface samples.
All drilling to data has been on Exploration Licence 27892, which is wholly owned by TNG Limited. Drilling at Mount Hardy in 2013 has been by diamond drill holes of either HQ or NQ size core, with core recovery consistently over 95%. Hole spacings vary depending on the target, but at Mount Hardy are around 30-40 metres across strike and down dip, with lines 60-80 metres apart (along strike).

==> picture [176 x 29] intentionally omitted <==
Hole collar locations have been picked up with standard GPS to an accuracy of 3 metres, while downhole position is determined by Reflex surveys every 30 metres. At the Mount Hardy Prospect the holes were drilled nearly perpendicular to the mineralisation and so approximate true thicknesses.
Sampling is by half cut core with samples being over intervals of 0.3 to 1.2 metres in length (determined by geological units), and of 2-5 kilograms weight. Sample preparation involves drying, coarse crushing and pulverisation of the complete sample to >85% <75 microns. Base metals were determined on a pulp sub-sample by four acid digest and ICP-AES finish, while gold and Pt/Pd values were based on a 50 gram Fire Assay charge with ICP read. Certified standards were inserted to check laboratory calibration and returned within acceptable limits.
All reported assay values have been composited with a 0.1% Cu cut-off and are length weighted averages. No intervals exceeding 1 metre of included waste are allowed.
Drilling continues on site and is likely to be complete by the end of April. Upon receipt of all results a full assessment will be undertaken to determine the next steps, which are likely to include more drilling later in the year.

TNG’s Managing Director Paul Burton said the third diamond hole had intersected significant grades of copper and coincident gold mineralisation some 80m along strike from the encouraging results reported in the first two holes.
“As we learn more about the mineralisation style at Mount Hardy, it continues to provide strong encouragement for a large project,” Mr Burton said. “It’s also important to note we that are on the edge of the Tanami region where significant gold prospects and mines occur.
“We have hit mineralisation is every hole completed to date and we are continuing to intersect sulphide and oxide mineralisation at depth beneath the extensive surface copper mineralisation delineated last year. Drilling is continuing and should be completed within the next week.”
