1.0 SUMMARY This report outlines the exploration carried on exploration licence 22921 (Titra) for the first year of grant ending 27 October 2003. The tenement was granted to Tanami Exploration NL (TENL) on 8 October 2002. TENL is a wholly owned subsidiary of Tanami Gold NL. Exploration on the Titra tenement was limited to a regional desktop review that encompassed all of the TENL tenements. This review identified numerous exploration targets within the region, several of which lie within EL 22921. The tenement contains favourable geology that could potentially host mineralisation similar to that found in the Tanami district. Grant of access to the tenement from the traditional owners is yet to be negotiated. Exploration of the tenement is severely hampered by thick sand cover. The cover completely conceals the basement rocks and renders any surface geochemical techniques ineffective. 2.0 INTRODUCTION The Titra exploration licence (EL 22921) is located approximately 200 kilometres northwest of Alice Springs and 10km north of Papunya. The tenement was granted to Tanami Exploration NL on 28 October 2002. EL22921 is accessed via the sealed Stuart Highway and Tanami Track, then unsealed roads 100km west from the Tanami Track, via Papunya. Access within the tenement is poor due to sand dunes. Station tracks provide what limited access is available. The tenement lies in the northwest corner of the Hermannsburg 1:250,000 map sheet. The application for the tenement was made in December 2000 on the grounds of favourable aeromagnetic features including major structures. No fieldwork was carried out during the first year of grant because an access agreement with the traditional owners is yet to be signed. 3.0 TENURE Exploration Licence 22921 was granted over an area of 500 blocks on 28 October 2002 Table 1: Tenement Details EL 22921 Tenement Blocks Km² Grant Date Expiry 2003 Covenant Titra 500 1,580 28/10/02 29/10/08 $66,500 Tanami identified 293 blocks which were suitable for relinquishment from EL 22921 and subsequently lodged a voluntary partial surrender in respect of those blocks with effect from 28 October 2003. The remaining area of EL 22921 is now reduced to 203 blocks. Negotiations with the traditional owners are currently underway in order to gain access to the tenement. 4.0 PREVIOUS WORK Previous exploration conducted within EL 22921 comprises drilling by CRAE and Alcoa during the 1970’s and 1980’s testing for roll-front uranium mineralisation hosted within Tertiary sediments overlying basement. No anomalous results were returned.

5.0 GEOLOGY The tenement lies within the Central Arunta Region comprising variably metamorphosed Proterozoic age sediments and granite intrusives. Aeromagnetic interpretation and isolated outcrops in the region suggest that the tenement is underlain by the Palaeoproterozoic Strangways Metamorphic Complex and the metasediments of the Lander Rock beds Group. The Strangways metamorphic complex comprises felsic and mafic granulites, felsic metavolcanics, ortho-quartzite and calc-silicate rocks. The Lander Package is the most widespread interpreted lithological package over the northern and western Arunta, and is dominated by interlayered pelites and psammites of turbiditic to shallow marine origin. The metamorphic grade is most commonly greenschist but localised rapid variations in grade up to granulite facies occur (Scrimgeour, 2003). The Lander Package appears to be equivalent to the Killi Killi Formation of the Tanami Group which hosts significant mineralisation in the Tanami region (Green, 2003). Several major east-west trending and northwest-southeast trending major structures run through the tenement, the most significant being the Desert Bore Shear Zone. Potentially these structures and associated second-order splays could be a focus for mineralising fluids and hence be suitable exploration targets. A blanket of Quaternary aeolian sand covers the entire tenement. Locally the aeolian sands mask thick cover sequences of Tertiary sediments. 6.0 FIRST YEAR EXPLORATION PROGRAM In early 2002 the tenement was included within an Arunta-wide bedrock geological interpretation and geophysical targeting exercise conducted by consultant geophysicist Dr Jayson Myers. The exercise drew on analogies between the Central Arunta region and the Eastern Succession of the Mt Isa region which hosts a number of major gold-copper and base metals deposits. In early 2003 Contract Geologist Dr Nathan Jombwe reviewed the Myers targets, developed new targets and conducted a ranking exercise (Jombwe, 2003). A conceptual target was identified within the southern portion of EL 22921. This target was identified as a major structure that could potentially host epigenetic shear zone gold mineralisation. During the review process gold targets were identified based on the criteria that they occur on a first and/or second order structure, with the higher-ranking targets on structural jogs or intersecting structures. Targets were then further evaluated on the basis of supporting metallogeny and previous exploration. Coincident magnetic and gravity highs were identified as possible IOCG type targets.

Total 66,500 During the second year of grant the primary aim will be to negotiate an exploration access agreement with the traditional owners to gain access to conduct first pass exploration. This will comprise wide-spaced drilling to test depth of cover and bedrock lithologies over conceptual structural and aeromagnetic targets. 9.0 REFERENCES Young, D. N., Edgoose, C. J., Blake, D.
