EXPLORATION RESULTS UPDATE: McARTHUR RIVER ZINC PROJECT AND LEGUNE IRON PROJECT
Assay results received from 2014 drill programs confirm extensive mineralisation; Spectral Hylogging of core awaited
Key Points
-
Results from reconnaissance drilling at McArthur River Zinc Project in the NT confirms the potential for the area to host McArthur River-style zinc mineralisation:
-
Highly anomalous geochemistry identified over a 9km continuous zone supports the genetic model developed for the area; and
-
Zinc results up to 0.2% and copper results up to 0.2% returned within broad sulphide intersections over 20m, confirming a metal-enriched system within prospective lithologies.
-
High-grade iron ore of up to 64.0% Fe intersected in two holes drilled at the Legune Iron Prospect at the Manbarrum Project.
-
Significant intersections returned adjacent to and down-dip of the Legune ochre pit hematite outcrop include: 14LHDDH001 4.3m @ 59.1% Fe from 4.9m 14LHDDH002 3.9m @ 59.4% Fe from 13.1m
-
Mineralisation is open down-dip to the west and north.
TNG Limited (ASX: TNG) is pleased to advise that it has received final assay results from the 2014 reconnaissance diamond drilling programs undertaken at its 100%-owned McArthur River Zinc Project (see Figure 1) and Legune Iron Prospect , part of its 100%-owned Manbarrum Zinc Project .
The programmes were undertaken to test the geological models for each project and to provide further information for future programmes. The programmes intersected mineralisation in all holes and will provide information for future exploration planning.
McArthur River Zinc Project
The McArthur River Project is located 60km south-west of the worldclass 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 discovery (Rox/Teck).

Two reconnaissance scout holes (Figure 1) were drilled targeting the prospective Wollogorang Formation, which has significant anomalous base metal surface geochemistry extending over 9km ( see ASX Announcement – 20 August 2014 ).
The mineralisation noted in these two holes has many similarities with that seen at the McArthur River Zinc Mine 60km to the north, including:
-
Fine grained pyrite-dominated sulphides within layering of host bituminous black shales;
-
Zn-Pb-Ag elemental association with low copper;
-
Strong IP geophysical anomalies; and
-
Stacked mineralisation lenses.

Figure 1: Location of the McArthur River tenements, 2014 drill holes, and positions of the cross-sections.
Work completed by TNG on this project over the last three years has confirmed the potential of the central portion of the Wollogorang Formation to host zinc-lead-silver-copper mineralisation of a similar style to that found at McArthur River ( see ASX Announcement – 16 September 2013 ).

Drilling was co-funded by the Northern Territory Department of Mines and Energy (NTDME) ( see ASX Announcement – 27 June 2014 ).
Drill-hole location information is shown in Table 1, with details of drilling and sampling outlined in Appendix 1. Samples were analysed by ALS in Perth by ICP method ME-ICP41a, with results presented in Table 2.
Table 1 – Hole collar summary details
| Hole_ID | Easting | Northing | Depth | Dip | Azimuth | Tenement |
|---|---|---|---|---|---|---|
| 14MCDDH001 | 597,347 | 8,112,564 | 151.2 | -75 | 270 | EL 27711 |
| 14MCDDH002 | 594,411 | 8,108,504 | 200.6 | -75 | 270 | EL30085 |
The best intersections are listed below, with all mineralisation found in the central “Ovoid Beds portion” of the Wollogorang Formation. Zinc in fine sphalerite is associated with very fine grained stratiform sulphides (pyrite and galena) in highly bituminous black shales.
| Hole No. | Interval | Thickness | Grade (%) |
|---|---|---|---|
| 14MCDDH001 | 60.0 to 69.0m | 9.0m @ | 0.08% Zn |
| 14MCDDH001 | 80.0 to 84.0m | 4.0m @ | 0.08% Zn, including |
| 82.0 to 83.0m | 1.0m @ | 0.14% Zn | |
| 14MCDDH002 | 19.0 to 20.0m | 1.0m @ | 0.21% Cu |
| 14MCDDH002 | 79.0 to 92.0m | 13.0m @ | 0.09% Zn, including |
| 80.0 to 81.0m | 1.0m @ | 0.20% Zn | |
| 14MCDDH002 | 94.0 to 102.0m | 8.0m @ | 0.08% Zn |
Maximum assay values were 2,020ppm zinc, 380ppm Pb, and 2,140ppm Cu, with nine values of zinc over 0.1%. There was a strong correlation between zinc, lead and silver, but copper values are low within the higher grade Zn-Pb stratiform mineralisation. Sulphide contents to 6% are indicated by the S% analyses (Table 2).
Analyses of copper in hole 14MCDDH002 from 19.0 to 20.0m returned 0.21% Cu in a core sample displaying both malachite and azurite (copper carbonate minerals). This mineralisation is supergene in nature and unrelated to the stratiform zinc mineralisation, showing that there is copper elsewhere in the system. TNG’s exploration is also targeting structurally controlled and/or Redbank-style breccia pipe copper mineralisation.
While both holes have over twenty metres of very encouraging fine grained sulphidic shales (6085m in hole 14MCDDH001 and 81-104m in hole 14MCDDH002), only part is significantly sphalerite-rich. With the very extensive geochemical anomalous zone there is potential for higher zinc, copper, lead and silver grades within this unit elsewhere on TNG’s 100% owned ground in this highly prospective area..
Figure 2 shows geological cross sections through each hole. Each has anomalous surface geochemistry associated with the outcropping position of the central part of the Wollogorang Formation (Ovoid Beds) and an IP anomaly corresponding with the down dip (0-100m below surface) position of this horizon. Assay results in each hole correspond closely with the surface geochemistry values (250-2500ppm Zn), despite being found in primary sulphides and up to 500m down-dip.
The mineralisation noted here on the Mallapunyah Dome is of a similar genesis to the McArthur mine, and, is worthy of further investigation. These two holes are separated by 5km, are centrally positioned within a 12km zone of surface geochemical anomalism (see Figure 3 and ASX Announcement –16 September 2013), and the prospective Wollogorang Formation is exposed over 17km within TNG’s tenements.

There is potential for further targets to be outlined by planned geophysics across the project area. The entire tenement package lies within the Batten Fault Zone, host to all of the significant resources outlined to date in the McArthur Basin including the recent Teena discovery.

Full assessment of these analytical results will await the completion of down-hole geophysics (also co-funded by the NTDME) and assessment of the mineralogical information obtained from
==> picture [596 x 30] intentionally omitted <==
==> picture [42 x 842] intentionally omitted <==
the Hylogging of both holes being conducted by the Northern Territory Geological Survey (NTGS). Down-hole electromagnetic (DHEM) and downhole magnetometric resistivity (MMR) geophysical surveying has been completed with results and interpretation expected prior to year end.
Hylogging involves scanning the core in the Shortwave Infrared (SWIR) and Thermal Infrared (TIR) portions of the electromagnetic spectrum to allow minerals to be identified, with the raw Hylogger data obtained in October currently being processed and interpreted by the NTGS team.
Legune Iron Prospect
The Legune Iron Prospect lies within TNG’s 100%-owned Manbarrum Project, which is located 80km north-northeast of Kununurra, just east of the WA/NT border, and less than 40km from the Joseph Bonaparte Gulf coast (Figure 3).
The project comprises five tenements (ELs 24395, 25470, 25646, and Authorities A24518 and 26581) held by TNG’s 100%-owned subsidiary Tennant Creek Gold (NT) Pty Ltd.
The Legune Iron Prospect falls on EL 24395, together with the Djibitgun Zn-Pb-Ag Mississippi Valley Type (MVT) resource and the Browns and Landandi MVT Prospects. TNG has conducted extensive exploration programs for MVT style Zn-Pb-Ag mineralisation along the south-eastern margin of the Bonaparte Basin since 2007, resulting in the delineation of the Djibitgun and Sandy Creek Zn/Pb/Ag resources ( see ASX Announcement – 11 March 2010 ).
The Legune Iron Prospect was discovered by TNG in 2008 ( see ASX Announcement – 2 July 2008 ), with outcropping hematite grading up to 67.1% Fe. From 2009 through early 2014 the area was optioned to Teng Fei Mining Limited ( see ASX Announcements – 25 November 2009 and 22 January 2014 ).
As Teng Fei was unable to progress work on the area, the ground was returned to TNG in January 2014, with TNG retaining 100% ownership while Teng Fei maintains a 3% royalty on any future iron ore production from the tenement.
Drilling of the iron prospect was completed in early-mid October 2014, following clearance from Aboriginal Areas Protection Authority (AAPA) and the Traditional Owners ( see ASX Announcement – 2 October 2014 ). Drill hole location details are provided in Table 3 below, while drilling and sampling details are outlined in Appendix 2. Analytical results are listed in Table 4.

Three holes were completed for a total of 158m (outlined in Table 3 and Figure 2). All holes were collared on Legune Hill (Figure 4) and above the exposures seen in the breakaway on the south side of the hill (Figure 5). A local Northern Territory contractor with a small track-mounted rig was used to minimise ground disturbance and it generated HQ diamond core samples.

Figure 3. Location diagram showing the Manbarrum Project tenure in the Northern Territory and the drill hole positions on Legune Hill.
Geological logging and analysis indicated the iron mineralisation was hosted in ferruginous sandstone sediment belonging to the Devonian Cockatoo Formation.
A consistent layer of ochrous hematite can be mapped through all three holes dipping very gently away from the exposures on the south-eastern side of the hill. The mineralisation extends to only minimal depth, with all high grade hematite less than 20 metres from surface. The hematite layer is open down dip, both to the west and to the north.
The significant hematitic iron ore intersections (at 50% and 40% Fe cut-offs) are listed below:
| Hole No. | Interval | Thickness | Grade Fe (%) | |
|---|---|---|---|---|
| 14LHDDH001 | 4.9 to 9.2m | 4.3m | @ | 59.1% Fe, including |
| 6.0 to 7.0m | 1.0m | @ | 63.5% Fe | |
| 14LHDDH002 | 13.1 to 17.0m | 3.9m | @ | 59.4% Fe, including |
| 15.0 to 16.0m | 1.0m | @ | 64.0% Fe | |
| 14LHDDH003 | 17.0 to 17.6m | 0.6m | @ | 43.8% Fe |
The >50% Fe intersections have low silica, phosphorus and alumina, as shown in Table 2, and the higher grade material would appear to be acceptable as commercial grade IODEX 62% Fe feedstock (in the event that future mining takes place).
The Legune Hill covers a 900 x 500m area, and with a thickness of 4-6m there is potential for several million tonnes of hematite material of this grade. Additional tonnage potential exists further to the west and north. Note: Drilling to date is of a very preliminary nature and insufficient to outline a Mineral Resource.

TNG’s Managing Director Mr Paul Burton said the 2014 drilling programmes had been successful in defining the potential for substantial mineralised systems at depth at the McArthur River project, while also outlining an attractive high-grade DSO project at Legune.
“McArthur River is an exciting project with a huge geochemical expression which we have now established continues at depth. We drilled two scout holes into a 9km zone. We can now refine our techniques to establish suitable traps or accumulation sites of mineralisation with follow-up exploration programs,” he said.

==> picture [42 x 842] intentionally omitted <==
“At Legune, we have established that the highly anomalous iron ore outcrop continues at depth with DSO tenor grades, although shallower than expected. This information will now be included into our broader understanding of all mineralisation at the Manbarrum Project,” Mr Burton added.
