ASX QUARTERLY EXPLORATION REPORT FOR PERIOD ENDED 30th JUNE, 2003

HIGHLIGHTS

  • Iron oxide associated copper-gold-silver-cobalt mineralisation intersected at the Titan Prospect has major similarities with Olympic Dam as confirmed by petrological analysis, detailed geological logging and geophysical signatures warranting further testing of the Titan system.
  • Mineralized basement intersected at Titan in hole RC-DD03T1002:
  • 154m at 0.08% Cu, 17ppb Au, 80ppm Co, 0.50ppm Ag and 40ppm U from 604m, $\circ$ including:
    • 30m at $0.15\%$ Cu, 28ppb Au, 155ppm Co, 0.43ppm Ag and 27ppm U from 652m: and.
    • $\frac{3m \times 0.50\% \text{ Cu}}{2 \times 95 \text{ pb}}$ Au, 175 ppm Co, 0.77 ppm Ag and 31 ppm U from $\blacksquare$ 653m.
  • Scout drilling at Saddle Hill located trace copper sulphides within Neoproterozoic sandstone; supporting the potential for Mt Gunson-style mineralisation or representing an Olympic Dam system halo associated with the gravity feature, which remains untested.
  • MVT style mineralisation encountered at the basal unconformity of the Andamooka Limestone at Shelf 6.
  • High-grade copper occurrence at Waterman's Plain located and tested; deeper Olympic Dam style target remains untested.

REVIEW OF OPERATIONS

Tasman Resources NL holds a 100% interest in the "Lake Torrens Project" comprising Exploration Licences 2988, 2989, 2543, 2594, 2642, 2733, 2772, 2832, 2835, 3006, 3007 together with applications 178/02 and 39/03.

Exploration for the quarter comprised drilling at the Waterman's Plain, Saddle Hill, Shelf 6 and Titan areas. Soil sampling was completed at Waterman's and at Saddle Hill.

1) Exploration Activities

i) Titan Prospect

The Titan Prospect consists of two very strong magnetic and gravity anomalies located 33km north of Olympic Dam.

During the Ouarter, a vertical hole was drilled to test that part of the geophysical anomaly interpreted to have the shallowest cover $(500m \pm 50m)$ coincident with the interpreted extension of the IP anomaly within the gravity anomaly. Hole RC-DD03TI001 (TI1) reached 458.8m before drilling problems led its abandonment. Hole RC-DD03T1002 (T12) was collared 20m away and drilled to 762.6m (the limit of the drill rig).

Hole TI2 reached Mesoproterozoic basement at 604.5m depth, the basement rocks comprise arkosic metarenites with an early pervasive 'red rock' alteration overprinted by weak to intense veining, vein networks and pervasive magnetite+haematite+chlorite±pyrite±chalcopyrite alteration

Widespread copper, gold, uranium, cobalt and silver mineralisation is present in TI2. Better assay results from TI2 are listed in Table 1. Maximum results for these elements are 1.2% Cu, 0.2g/t Au, 0.1% Co and $12g/t$ Ag, all in 1m samples. The overall tenor of mineralisation in TI2 is generally similar to BD1, but peak values are greater. However, alteration in TI2 appears to be stronger, with significant development of several different styles of haematite and chlorite esericite. Narrow matrix-supported haematite breccias occur in the lower portions of the hole together with feldspar-phyric dykes.

Tasman Resources considers there to be encouraging signs that geological processes similar to those that operated at Olympic Dam have taken place at Titan, and that the potential for major copper-gold mineralisation warrants further drill testing.

A comprehensive assessment of the geology of BD1 and RC-DD03TI002 is currently underway, comprising detailed logging, petrography, mineragraphy, SEM analysis and petrophysical measurements. This data will be incorporated with our existing geophysical data and used to provide improved geophysical modelling of the Titan system.

An integrated prospect-scale geological model of Titan based on gravity, magnetics, IP, resistivity, CSAMT, lithology and alteration studies, fluid inclusion results and structural/textural analysis will be established to identify vectors towards the core of the mineralised system and guide drill testing.

Tasman Resources aims to identify the next drill targets at Titan during the next Quarter and to then proceed with this drilling before the end of this year's field season.

ii) Waterman's Plain Prospect (Marathon M1)

Waterman's Plain is located approximately 30 km northeast of Olympic Dam and comprises a zone (6km by 2.5km) of complex gravity and magnetic anomalism with associated near surface $( $200\text{m}$ )$ chargeability anomalies. An old shaft mined for copper has recently been discovered at Waterman's Plain

A deep ( $>$ 500m) magnetic/gravity target is present at Waterman's Plain, however the activities of the Ouarter were directed at testing the MVT potential of near surface short-wavelength residual gravity anomalies with associated IP chargeability anomalies.

During the Quarter, nine lines of soil samples were collected and analysed using Amdel's Deepleach 11 partial extraction. Results were erratic, though a number of copper anomalies were revealed that supported the geophysical targets. A total of thirteen holes were drilled testing various targets at Waterman's Plain. Eight drill holes targeted the IP anomalies associated with residual gravity highs. The remaining five holes were drilled under and around the old shaft.

All eight holes testing the IP targes drilled through Andamooka Limestone (two were collared in Yarrawurta Shale) into the underlying Yarloo Shale. Significant amounts of iron sulphides (up to 20% pyrite and marcasite) where encountered at various zones within the Andamooka Limestone, though in most cases the greatest sulphide concentration was within the upper zones of broad arches or antiforms of the limestone (as revealed by the resistivity data).

A zone of alteration (5m to 10m thick) together with weak mineralisation associated with the basal unconformity of the Andamooka Limestone was intersected by these holes. Assay results from the Andamooka Limestone were very low, better results from the basal zone are listed in Table 2.

Table 2: Waterman's Plain Drilling - Better Assay Results

High grade copper and silver mineralisation (up to 40% Cu and 28.4ppm Ag) was evident in gossanous samples discarded at the old shaft at Waterman's Plain. Tasman Resources drilled a single drill hole under the old workings to assess the continuity and depth extent of the mineralisation. Hole RC03WP007 intersected goethitic zones with minor visible green copper which returned assays (3m composites) from the $12-21$ m zone averaging $3.3\%$ Cu, including 3m at 9.82% Cu and 4.3% Pb.

Mapping around the shaft suggested a NNE-trending structure as the possible control on the mineralisation, whilst the geophysical datasets suggested WNW offsets along this structure may be localising the mineralisation. Soil samples over this NNE zone returned anomalous copper in the partial extraction results.

Follow-up close spaced drilling of four holes (a hole under WP7, 10m step outs north and south, and a scissor hole) failed to intersect any additional mineralisation around the shaft. Goethitic zones were intersected though they are all on roughly the same vertical depth. suggesting a palaeo-watertable affect, and returned no anomalous metal results from the assays.

The mineralisation mined in the shaft at Waterman's Plain is interpreted to be very localised and structurally controlled, probably at the intersection of two structures. The origin of the copper and other metals at Waterman's Plain is unclear, though the gossan textures suggest original sulphides which support a deeper primary source. The metals may be related to the deeper magnetic/gravity target at Waterman's Plain or may represent examples of the karst-fill style of mineralisation.

The shallow cover at Waterman's Plain warrants additional exploration to locate other, larger, examples of this high-grade mineralisation style; whilst the deeper Olympic Dam style target also requires further investigation.

iii) Saddle Hill Prospect (Marathon M2)

Saddle Hill is located 35km northeast of Olympic Dam. The prospect lies on the northeasttrending Marathon gravity/magnetic zone and covers the shallowest gravity anomaly along the trend. IP electrical surveys have defined a central resistive zone interpreted as a plug or horst with anomalous chargeability responses on its margin. Two lines of soil samples collected over Saddle Hill returned anomalous Cu, Pb, Zn, Ni, Co, Au, Ag, U and REE results from selective extractions.

A 60° scout hole to investigate the main chargeability feature was completed during the Ouarter. Hole RC-DD03SH001 (SH1) was drilled to 462.6m and drilled through Yarrawurta Shale, Andamooka Limestone, Yarloo Shale and Simmens Ouartzite.

After testing the interpreted position of the IP anomaly the hole was extended to attempt to reach Mesoproterozoic basement and test the source of the gravity anomaly at Saddle Hill. Unfortunately the hole suffered excessive steepening and revised geophysical modelling indicated that the target was unlikely to be reached so the hole was stopped.

No clear source for the IP anomaly was identified in SH1. Traces of disseminated chalcopyrite (copper sulphide) were noted at several locations within the Simmens Quartzite, in more reduced sections of the rock. Assay results from SH1 were subdued.

The Saddle Hill Prospect remains a high priority target – the IP anomaly has not been explained and the soil geochemistry is distinctly anomalous. The presence of trace chalcopyrite within the Neoproterozoic supports the potential for either sediment hosted mineralisation (for example, Mt Gunson style targets) or may represent an Olympic Dam-type system halo associated with the gravity/magnetic feature.

iv) Shelf 6 Prospect

Shelf 6 Prospect is located 50km northeast of Olympic Dam. Tasman Resources has been targeting base metal mineralisation hosted by Cambrian and Neoproterozoic sediments of the Stuart Shelf.

A series of four percussion and three core holes were completed at Shelf 6 during the Ouarter to test a co-incident gravity/chargeability anomaly and a shallow chargeability feature.

The holes drilled through shallow aeolian sand cover and Tertiary sandstone before drilling through a thin ferruginous duricrust at the top of the Andamooka Limestone and then through the Andamooka Limestone into the disconformably underlying Yarloo Shale.

Better assay results from the drilling are listed in Table 3.

Table 3: Better Assay Results from Shelf 6

The basal 12m of the Andamooka Limestone is distinctly altered with an interpreted silica-clay assemblage. Sulphides, including chalcopyrite, tennantite, sphalerite, galena, pyrite and marcasite are present as interpreted late stage infill of fractures, stylolites and porous zones, in amounts up to $1\%$ over 1m intervals.

The iron enriched zone at the top of the limestone is acting as a geochemical trap and contains elevated and anomalous values for Cu, Pb, Zn, Ag, As, Au, Mo and Co.

This drilling programme has clearly shown the presence of base metal mineralisation and alteration at the base of the Andamooka Limestone. This zone offers an encouraging target horizon for significant "Mississippi Valley Type" base metal mineralisation in the Shelf 6 vicinity and elsewhere on the Stuart Shelf. The results will now be reviewed in detail to determine Tasman's ongoing exploration strategy at Shelf 6 and on the portion of the Stuart Shelf within Tasman's project area for base metal mineralisation.
