-
TNG continues to focus on its flagship Mount Peake Vanadium Project, where the Feasibility Study is in its final stages and progressing according to plan
Australian strategic metals company TNG Limited (ASX: TNG) is pleased to announce that it has delineated an extensive zone of high-grade surface copper mineralisation from mapping and rock chip sampling undertaken at its 100%-owned McArthur River Project in the Northern Territory (Figure 1).
The work was carried out while TNG continues its primary focus on the completion of the Feasibility Study on its flagship Mount Peake Vanadium Project, which is continuing to progress on schedule and according to plan. Updates on this work, including the TIVAN® pilot testwork, are expected with the completion of each phase and after assessment and review of results.
A program of field mapping, soil sampling and rock chip sampling was conducted at the McArthur River Project to follow up the high grade 48% copper analysis located during earlier reconnaissance sampling (see ASX Announcement – 16 February 2015). This work was conducted as part of the ongoing background assessment of the assets, which have been included in the recently approved demerger of Todd River Resources.
The field work has confirmed the very high prospectivity of the McArthur River Project, with these results indicating a newly discovered zone of sedimentary-hosted stratiform copper-silver mineralisation which represents a significant exploration target and potential new mineralisation style for this area.
Sediment-hosted stratiform copper deposits are an important and economically attractive, world-class mineral deposit style. Examples of these are demonstrated by the super-giants of the Kupfershiefer in north-central Europe and the Copper Belt of Central Africa.
The McArthur River Project is located 60km south-west of the world-class McArthur River Zinc Mine, operated by Glencore, and within the Batten Fault Zone, which hosts several other base metal resources including the recently outlined Teena deposit (Rox/Teck).

McArthur River Sampling Program
Detailed geological mapping at 1:2500 scale was completed by TNG geologists year over an area of approximately 3 square kilometres (as shown in Figure 1). Systematic Portable XRF (pXRF) and -80# soil sampling and rock chip sampling was also undertaken with details outlined in Appendix 2.
48 rock samples were collected with all samples analysed for a 33-element suite. Results of greater than 1% copper are shown in Table 1 and results of all significant elements and sample coordinates are listed in Appendix 1. Significant copper results >40% Cu are shown in Table 2. Laboratory analysis of the rock samples returned a total of seven samples with >40% Cu, 12 samples greater than 10% Cu and 19 samples above 1% Cu. These results enhance and confirm the extent of the potential copper horizon.

All anomalous samples came from a shale band in the lowermost Wollogorang Formation (Figure 2). This shale (Pto1) is approximately ten metres thick and bound below by the Settlement Creek Dolerite and above by a dolomite subunit within the Wollogorang Formation (Pto2).
The dolomite exposures are prominent, forming low (2-10m) breakaways with the shale poorly exposed on the scree slope below the breakaway (Plate 1). Stratigraphy in the area displays variable but shallow dips (0-20 degrees), mostly dipping towards the east.
Copper anomalism was found in two main areas (see Figure 2). A total of 23 samples were taken in the vicinity of the original sample at approximately 593,373mE 8,109,079mN. These samples were spread over an area of 150m by 120m and returned four (five including the original sample) assays of greater than 40% Cu. Seven samples returned values of greater than 10% Cu, while the eight samples showing more than 1% Cu were spread over an area of 30m by 50 metres.
An exposure of the shale along a NNE facing breakaway some 300-500m to the north returned three rock samples with >40% Cu results. The anomalous samples were all taken from the same stratigraphic shale unit and were spread over 250m of strike exposure along the breakaway.
The copper is present as malachite (green hydrated copper carbonate) and chalcocite (black supergene copper sulphide) in all samples with more than 1% Cu (see Plate 2). Significant tenorite (black high-grade copper oxide) and/or native copper may also be present (as there is insufficient sulphur present to generate the high copper grades as sulphide).

There is a distinct multi-element association which is displayed by these samples in Cu-Bi-Ag-Au-Mo. The multielement anomalism for the two areas is outlined in Table 2.
Silver correlates well with copper and is highly anomalous with ten samples returning over 40 g/t Ag and 13 above 10g/t, with a maximum value of 68 g/t. Gold was analysed only in 18 samples and, of those, five results exceeded 0.05 g/t, with a maximum value of 0.10 g/t Au. All anomalous gold results came from samples with >40% copper.
Bismuth is also highly anomalous, with results to 2220 ppm Bi , while the background is <20ppm. Molybdenum (Mo) is elevated in the copper anomalous samples with a maximum value of 50ppm in sample MC15502 which has 45.6% Cu (Table 1).
TNG has been active in this area since 2011, although most work to date has been directed towards the zinc potential higher in the stratigraphy (see ASX Announcements – 16 September 2013, 20 August 2014, and 14 October 2014). Late in 2014, NTGS-sponsored diamond drilling was completed on two combined geochemical and geophysical zinc targets.
Sampling of this drill core provided numerous sulphides in an organic and sulphide rich portion of the Ovoid Beds subunit of the Wollogorang Formation (Pto3) and returned results of over 0.2% for both zinc and copper ( see ASX Announcement – 18 December 2014 ). The zinc was associated with pyrite and sphalerite fine sulphides in the most organic rich portion of the stratigraphy. Very high (to 7% TOC) organic content is seen in this interval of core.
The extreme high copper grades seen (10-48% Cu) are a result of supergene enrichment in the weathered profile and likely persist to around 100m below surface. The likely original chalcopyrite hypogene copper has been upgraded to supergene sulphide species (chalcocite, bornite, native copper) which were then replaced by carbonate/oxide species (malachite, tenorite) resulting in the extreme grades seen.
These results indicate a new sedimentary hosted stratiform layer of copper mineralisation has been outlined over an area in excess of 600m by 400m. It is several metres thick and persistent under very thin dolomite cover covering an area of at least 0.5 square kilometres. The horizon dips to the east and would be present over a couple of square kilometres at less than 100m depth below surface and reappears to the south of the area mapped. Soil sampling ( see ASX Announcement – 16 September 2013 ) also highlights the copper potential in the south.
It would be unusual if the mineralised zone was not continuous as is normal with sedimentary hosted stratiform layers but further work is required to establish this.
The McArthur River Project is part of a portfolio of non-core base metal assets held by TNG in the Northern Territory which have been included in the demerger of Todd River Resources. This is consistent with TNG’s focus on advancing its world-class Mount Peake Vanadium-Titanium-Iron Project to development.
The further evaluation of this prospect will be determined by Todd River Resources once the demerger has been completed, and future work programs would be likely to include trenching and geophysics to determine the full extent of copper anomalism before undertaking drill testing.
TNG’s Managing Director, Mr Paul Burton, said the copper results from McArthur River were encouraging and demonstrated the prospectivity of the project.
“This has the early indications of very large and potentially significant copper exploration target,” Mr Burton said. “In many respects this vindicates our decision to include this asset with our other significant Northern Territory mineral exploration assets with the demerger into Todd River Resources – which will be able to pursue an appropriate exploration strategy to unlock their full value for shareholders.

“TNG shareholders will continue to have significant exposure to these assets through the proposed in-specie distribution of shares once the demerger has taken place. A timetable for this is anticipated soon and I expect to be able to provide an update on this following our Feasibility Study results from Mount Peake,” he said.

About TNG
TNG is building a world-scale strategic metals business based on its flagship 100%-owned Mount Peake Vanadium-Titanium-Iron Project in the Northern Territory. Located 235km north of Alice Springs, Mount Peake will be a 20-year plus project producing a suite of high-quality, high-purity strategic metals products for global markets including vanadium pentoxide, iron oxide and titanium dioxide. The project, which will be a top-10 global producer, has received Major Project Facilitation status from the NT Government.
The Mount Peake Feasibility Study is well advanced and due for completion by mid-2015, paving the way for project financing and development to proceed. An integral part of TNG’s emerging strategic metals business its 100% ownership of the unique and patented TIVAN® hydrometallurgical process, which offers significantly lower capital and operating costs, lowers risk and successfully extracts two other valuable metals from the resource in addition to vanadium – titanium dioxide and high-purity iron oxide.
Vanadium is a highly strategic metal which is used as an alloy in steel. It is also in strong demand for use in energy storage, with vanadium redox batteries used to store electricity generated by solar and wind power, and lithiumvanadium ion batteries used to power hybrid cars.
