Final report for EL 10158 'Mt Ruby', from 21 May 2002 to 20 April 2006

Abstract

Tanami Gold NL (TGNL) identified the potential for Selwyn-style copper-gold and Coronation Hill-style gold-PGM mineralisation in the Harts Range region of Central Australia. TGNL, through its wholly owned subsidiary Tanami Exploration NL (TENL), acquired a significant tenement holding in the district to test for these styles of mineralisation. These tenements formed the Harts Range Project. EL 10158 'Mt Ruby' is located approximately 130 kilometres ENE of Alice Springs and was part of TENL's Harts Range Project. It was granted on 21 May 2002 to TENL and surrendered on 20 April 2006. This report describes the exploration on from grant to surrender. During its first year of tenure, EL 10158 was the subject of a joint venture agreement between TGNL and Teck Cominco Australia Pty Ltd (Teck) and BHP-Billiton Pty Ltd (BHPB). Geodiscovery Pty Ltd managed the exploration for Teck-BHPB on the Albarta Area EL 10158. No work was done during this period on the relinquished tenement area. EL 10158 is interpreted to be underlain by high metamorphic lithologies of the Entia Gneiss Complex of the Strangways Metamorphic Complex, the Ilogwa Shear Zone and in the southern tenement area by gneisses of the Arltunga Gneiss Complex. TENL carried out rockchip sampling for a total of 25 samples in 2001 and 2003 on the relinquished tenement area. Slightly elevated gold values up to 20 ppb were returned. EL 10158 was also included in regional prospectivity studies and in April 2006 was recommended for relinquishment.
