Final report for EL 22761 'Harry Creek' from 2 April 2002 to 10 March 2005

Abstract

EL 22761 'Harry Creek' is situated in Central Australia about 40 kilometres north of Alice Springs. The tenement was granted in April 2002 to Teck Cominco Australia Pty Ltd (Teck) and transferred to Tanami Exploration NL (TENL) in March 2003. TENL is a wholly owned subsidiary of Tanami Gold NL (TGNL), a publicly listed company. EL 22761 was surrendered on March 10, 2005. This report covers the exploration conducted by Teck and TENL over nearly three years of tenure. Teck targeted Broken Hill-type (BHT) mineralisation hosted by sillimanite and garnet-bearing metasediments within the Wigley package. The target zones are rock packages associated with magnetic linears and more discrete magnetic anomalies which may represent alteration products. Within the surrendered area reconnaissance geochemical sampling and ground magnetics were carried out by the GeoDiscovery Group (consultants) for Teck. Teck considered the results for EL 22761 inconclusive due to extensive alluvial cover and lack of outcrop. No significant base metal anomalism was located. Within the reconnaissance sampling Teck also completed limited drainage sampling for heavy minerals, which were followed up by drainage sampling (3) and rock chip sampling (1) by Flinders Diamonds Limited (Flinders). TENL reviewed the work by Teck and carried out rock chip sampling to test narrow northeast trending retrograde schist zones for gold mineralisation. Based on lithology, Teck's inconclusive results and TENL's disappointing rock chip results the tenement was recommended for relinquishment.
