The fieldwork program, carried out by TNG geologists, comprised soil sampling, mapping and rock chip sampling focussing on eight priority targets identified by the recently completed HELITEM[®] and ground EM surveys conducted over the Mount Hardy Project area ( refer – ASX release 16[th] July 201 2).
Initial analysis of the rock chip samples using a Niton-XRF portable analyser has returned high-grade copper results from four of these locations, including a large, coherent copper-in-soil anomaly* extending over 550m x 160m and grading above 200ppm Cu at Mount Hardy. All samples have been submitted to the laboratory for multi-element analyses.
EM Target #1
EM Target #1 (see Figure 1) is defined as a strong (250 Siemens) NW plunging shoot conductor centred at 761950mE and 7552975mN (see Figure 3).
Mapping and soil sampling in the vicinity outlined existing workings with abundant >1% Cu material, as well as significant zinc and lead values. A major fault zone trending NW/SE cuts through the area in the vicinity of the conductor and there is minor associated copper mineralization. A second NNE striking strongly mineralised copper trend appears to be cut by the WNW line.
Sampling over EM Target #1 produced rock copper results of up to 28% Cu . Along the NNE trending zone, rock copper results exceeded 1% Cu over a 100m x 25m area. Within this area 59 Niton results were greater than 1% Cu, and, of these, 36 were >10% Cu. The maximum value for copper was 31%. Zinc results show 24 samples >1% Zn (maximum 21.8% Zn ), and lead results had 40 sample analyses >1% Pb (maximum 36.8% Pb* ).
Figure 1 (above) shows a rock sample from EM Target #1 area with six Niton results ranging up to 26.4% Cu, 19.8% Zn and 14.7% Pb. This sample was from 100 metres NW of the main mineralised NNE trend.

The Browns Mine area, 6.5km west of Mount Hardy (see Figure 3), was mapped and soil sampled over an 800m x 300m area, and a single large quartz vein hosting copper mineralisation was identified.
Strong copper mineralisation extends over a 150m strike with 14 of the 19 Niton rock results returning >1% Cu and a maximum value of 38.9% Cu. Figure 3 (lower) shows a sample from Browns with up to 26.7% Cu in Niton values.

EM Target #2
EM Target #2 had anomalous gossans and geochemistry with a modest soil response in the area of the EM target (six values >75ppm Cu and maximum 180ppm Cu), and rock sample results from two exposed veins returning Niton values up 46.6% Cu.*
Mount Hardy Copper Mine Area
At the Mount Hardy Mine area mapping, soil sampling and rock chip/channel sampling has outlined a strong and coherent copper-in-soil anomaly covering an area of 550m x 160m and grading >200ppm Cu ( Figure 4 ).
Peak values of greater than 1% Cu were noted in the vicinity of the historic mine workings, and 11 results of >800ppm Cu outline the core area.
In addition, rock chip samples with copper grades of over 1% Cu were collected along a strike length of 400 metres. Of a total of 276 Niton readings, 129 rock sample values were >1% Cu, and of these, 58 were in excess of 10% Cu* .
Sampling of an old costean (circa 1960s) returned 50 metres of >0.1% Cu in systematic 1m sampling using Niton* analysis. The costean was oriented across strike, crossing three mineralised veins mapped at surface. Seven values exceeded 1% Cu, with peak values of 4.1% Cu, 4.9% Cu, 8.6% Cu and 9.1% Cu. Rock samples (continuous channel chips) have been submitted for analysis.
Comment
TNG’s Managing Director, Mr Paul Burton, said he was encouraged by the field work results from Mount Hardy, which confirmed the excellent prospectivity of the region and underlined the success of TNG’s exploration techniques.
“While these are only preliminary results and, subject to final laboratory assay, we are very encouraged by the high copper grades that have been returned from these initial prospects, which highlight how effective the state-of-the-art HELITEM[®] survey system has been in identifying mineralised targets. EM Targets 1 and 2 have turned out to be exceptional,” he said.
Final assay results from the rock chip sampling program are expected to be received from the laboratory in early October, allowing a full assessment of the fieldwork program.
TNG is then planning to commence drilling at the most promising EM targets – Targets 1, 2, 4 and 5 (see Figure 3) – during the next Quarter, pending receipt of necessary approvals, and will also commence further field sampling work including re-sampling located historic drill core to gauge hypogene mineralisation style. Subject to receipt of approvals, drilling should commence in October.

Mr Burton said TNG has an exceptionally active exploration program planned over the forthcoming year.
“TNG has one of the largest portfolios of prospective copper ground in the Northern Territory with over 8,000km[2 ] under licence. We are increasingly excited by the high quality of our copper assets in the Northern Territory, with each of the exploration programs we’ve conducted to date highlighting potential for the delineation of economic copper mineralisation,” he said.
“The further exploration of this portfolio will be a key focus for TNG throughout 2013 in parallel with the development of our flagship Mount Peake strategic metals project.”
