Report for September Quarter 2013
DETAILS
VULCAN IOCGU PROJECT, South Australia (100% Tasman)
Following a break in exploration to resolve site access limitations, hole VUD 16, the eighth hole to be drilled under the Tasman- Rio Tinto Exploration (RTX) Farm in and Joint Venture Agreement over EL 4322 commenced towards the end of the Quarter and is still in progress. VUD 16 was collared at 6657112N, 695059E (GDA 94; MGA Zone 53, Az. 180[o] , Incl. -60[o] ) and is designed to test the south-west portion of the Vulcan IOCG target.

During the current quarter assay results were received from holes VUD 14 and 15 which had been completed in the previous quarter.
VUD 15
VUD 15 was the seventh drill hole to be completed under the Tasman – RTX Joint Venture/Farm In Agreement. The hole was designed to test for high grade IOCGU mineralisation associated with the very large, northern part of the Vulcan target zone, following up mineralisation intersected in drill holes VUD 3 and VUD 8. VUD 15 was collared at 693,961mE and 6,660,700mN (GDA 94; MGA Zone 53), and inclined at -80 degrees towards the south west (see Figure 2). The hole was finished at 1378m.
VUD 15 intersected the basement rocks of interest at 905m down hole, and then a very thick sequence of strongly IOCGU-style altered and variably mineralised basement rocks over more than 400m down hole, including several intersections of essentially pure hematite breccias, including one over 200m thick down hole. Photos of some of the mineralised drill core are shown in Figures 3 to 5.

Figure 2: Vulcan Project: residual gravity image showing all drill holes completed to date (GDA 94; MGA Zone 53). The most recent hole VUD 15 is labelled in red. Surface projections of basement intersections in the inclined holes are shown in white. These projections show how relatively little of the Vulcan target has been tested.
Most of this mineralisation occurs in a series of separate, weak- to moderate-strength intersections, and the highest are summarised in Table 1 below. The majority of the mineralisation occurs within the very thick sequence of IOCGU-style altered rocks and hematite dominated breccias (Figures 3& 4). The average copper grade over 435m down hole from 905m is 0.26% Cu.

Report for September Quarter 2013
Notes to Table 1:
Assays are for down hole intersections, and at this stage the true width of the mineralisation intersected is not known. Assay results are based on analysis of one metre half core diamond saw split samples of NQ diamond drill core. Average assays for the intervals stated above were calculated by weighting by sample length and sample density.
Samples were crushed and pulverised, and analysed as follows: Au by fire assay using the Genalysis fire assay scheme FA25/MS with a 1 ppb detection limit. Cu and Fe was analysed using Genalysis scheme 4A/OE (1ppm and 0.01% detection limit), involving a multi acid digest with an inductively coupled plasma optical emission spectrometry finish. Ag and U3O8 were analysed using Genalysis scheme 4A/MS (0.05ppm and 0.01ppm respectively), involving a multi acid digest with an inductively coupled plasma mass spectrometry finish. High Fe assays (mostly >50%) were reanalysed using Genalysis scheme FB6/OE (0.01%) involving a lithium metaborate fusion with an inductively coupled plasma optical emission spectrometry finish.
The highest grade copper mineralisation however, is probably remobilised and occurs within the upper portion of a mafic dyke (Figure 5) which was intersected from 1310 to 1343m. Several one metre assays over 4% Cu are included in this interval. Note that the intersections stated are down hole widths only, and at this stage the true widths are not known.

Report for September Quarter 2013
==> picture [68 x 26] intentionally omitted <==
Preliminary iron assays indicated that many of the individual one metre assays for these samples are above 50% Fe, and due to these very high levels assaying for iron was repeated by a more suitable analytical method for very high iron contents to ensure accuracy. New averaged assays received include 180m down hole at 60% Fe from 1,123m in VUD 15, and 240m down hole at 61% Fe from 840m in VUD 9. Iron in both holes is present dominantly as hematite (see Figures 6 &7).
If the Vulcan system was much closer to the surface these very iron-rich intersections would have been of economic interest in their own right. As some of the copper mineralisation intersected in VUD15 is associated with massive hematite there is potential for the high iron content to add further value to any future economic copper intersections at Vulcan.
The intersection of mineralised, highly favourable host rocks in VUD 15, coupled with the encouraging results in the nearby drill holes, in particular VUD 3 and 8 has substantially enhanced the prospectivity of this northern section of the Vulcan gravity target.

VUD 14
VUD 14 was collared at 696,410mE; 6,658,325mN (GDA 94; MGA Zone 53) and inclined at -80 degrees towards the south west (see Figure 1). The hole was completed at 1488m, and intersected 573m of variably altered and weakly mineralised basement rocks, but failed to intersect the zone of interest or any significant mineralisation. Assay results have confirmed the lack of significant mineralisation in this drill hole.
FURTHER WORK
Further drilling under the Tasman/RTX Joint Venture/Farm In Agreement had been temporarily suspended from late June until site access limitations could be resolved. Drilling resumed in mid September.
In order to accommodate this delay, Tasman and RTX have agreed to extend the latest completion date for the initial 12,000 metre drilling programme currently being undertaken pursuant to the Joint Venture/ Farm In Agreement, until 31 January 2014.
After completion of VUD 16 only one hole remains to be drilled to complete this programme.

Report for September Quarter 2013
Background to the Vulcan Project
Tasman identified Vulcan as a prime IOCGU target in 2009, based on the presence of a very large gravity anomaly, supporting magnetic and seismic anomalies and Vulcan’s location close to key tectonic (structural) lineaments, which had previously been used in the original targeting of Olympic Dam by WMC in the mid-1970s. Tasman’s initial discovery drill hole, VUD 001, intersected the Vulcan IOCGU system late in 2009.
Eight diamond drill holes had been completed by Tasman at Vulcan between 2009 and early 2011. All exhibit IOCGU-style alteration and/or mineralisation, including copper, gold, uranium, silver, molybdenum and rare earth elements. Age dating of the mineralisation at about 1,590 million years confirms that Vulcan belongs to the same “family” of deposits as Olympic Dam, Prominent Hill and Carrapateena.
Tasman has entered a Farm In/ Joint Venture with Rio Tinto Exploration (RTX) covering the whole of EL 4322, including the Vulcan discovery. Under the joint venture, RTX has paid to Tasman $10 million and Tasman is accordingly managing an exploration programme consisting of 12,000m of drilling.
OTHER PROJECTS
Tasman has gold and base metal projects at Parkinson Dam and the Central Gawler Craton in South Australia (Figure 8). No activity occurred on these during the quarter.
