Outstanding copper grades of 47% and 48% Cu and 68gpt silver from reconnaissance rock chip sampling
HIGHLIGHTS
-
Rock chip sampling results of 48% Cu, 47% Cu and 68gpt Ag have been returned to the west of previously reported drill-hole 14MCDDH002 at the McArthur River Zinc-Copper Project, in the NT.
-
Outcrop shows a mixed supergene sulphide and carbonate/oxide copper-bearing formation.
-
This new zone extends over an area of 300m x 600m within a large 700m x 1400m area of soil anomalism.
-
These results further enhance the prospectivity of the McArthur River Project, which is proposed for inclusion in the spin-off of TNG’s non-core base metal assets via Todd River Resources.
TNG Limited (ASX: TNG) is pleased to advise that it has significantly expanded the exploration potential of its 100%-owned McArthur River Project in the Northern Territory (Figure 1), following the discovery of a significant zone of high-grade copper mineralisation at surface.
The Company has received analytical results from a recent reconnaissance program of surface rock chip sampling at McArthur River including exceptional high copper grades of 47% Cu and 48% Cu . The results define an immediate priority zone for follow-up drilling.

The McArthur River Project is located 60km south-west of the world-class McArthur River Zinc Mine (Figure 2) operated by Glencore, and within the Batten Fault Zone, which hosts several other base metal resources, including the recently outlined Teena deposit (Rox/Teck).
The Project is part of a portfolio of non-core base metal assets held by TNG in the Northern Territory which are intended to be included in the demerger of Todd River Resources, planned for later this year. This is consistent with TNG’s focus on advancing its world-class Mount Peake Vanadium-Titanium-Iron Project to development.

Previous exploration has focused mainly on the zinc prospectivity of the area but this recent work by TNG indicates a new area of potentially significant copper prospectivity.
Recent work by TNG at McArthur River highlighted the zinc and copper potential of the tenements ( see ASX Announcements – 16 September 2013, 20 August 2014, and 14 October 2014 ), with reconnaissance drilling to test the geological model completed at two target zones based on anomalous surface soil geochemistry and coincident geophysical (IP) conductors.

Sampling of this drill core proved an intersection of the prospective lithology, the Wollogorang Formation with numerous sulphides and returned results of over 0.2% for both zinc and copper ( see ASX Announcement – 18 December 2014 ).

As part of a follow-up exercise, rock samples were collected during routine cross-section traversing related to the drilling that was undertaken in September/October 2014.
During this process, a significant area of surface outcropping rocks containing malachite and chalcocite (copper-bearing minerals) were noted and collected in a large zone of brecciated shale near the base of the prospective Wollogorang Formation to the west of previously reported hole 14MCDDH002 (see Figure 4 below showing an enlarged view of the location of the copper rock chip sample and extent of the copper soil anomaly area, McArthur River Project).

Analytical results for the sample are shown in Table 1 below, while sampling details are outlined in Appendix 1. Copper returned >40% (above the upper detection limit of the technique) in the four acid digest analysis (ME-ICP61a/Cu-OG62), and so two new samples taken from the original pulp powder were analysed by XRF method (ME-XRF15c) resulting in grades of 48.3% and 47.9% copper.

The sample also contains highly anomalous silver, grading 68ppm Ag, with background zinc and lead. The sample has tenorite (high grade and dark/black “earthy” copper oxide mineral) present and chalcocite, indicative of hydrothermal alteration.
During 2013/2014, TNG focused on the zinc potential within the central Wollogorang Formation – which is similar in many ways to the mineralization seen at the world-class McArthur River Zinc Mine, located 60km to the north ( see ASX Announcement – 20 August 2014 ).
This high-grade copper sample provides significant encouragement that economic grade copper mineralization may also be found within the tenement package. A program of rock sampling, geological mapping, and geophysics covering this significantly anomalous area has been designed and may be conducted early in the coming dry season.
TNG’s Managing Director, Mr Paul Burton, said the discovery of an extensive zone of high-grade surface copper mineralisation was a significant development for the McArthur River Project.
“This further demonstrates the substantial untapped exploration potential within our portfolio. We have so far been focusing on the potential for McArthur River to host a world-scale zinc system, which we believe remains a very credible and realistic exploration opportunity. This latest discovery shows the potential for high-grade copper in the near-surface environment, which is an exciting development which adds substantial value to the project.”
