Altjawarra Craton Diamond Project Final technical report for EL 23965 'Gordon Creek' for reporting period 24 May 2004 to 23 May 2005

Abstract

Exploration License EL 23965 (Gordon Creek) is located within Elkedra Diamonds NL's Altjawarra Project Area. The tenement was granted on 24th May 2004. This report details all work carried out by Elkedra Diamonds NL on the tenement until it's relinquishment on 23rd May 2005. The Altjawarra Project Area is located approximately 400 km east-northeast of Alice Springs in the Northern Territory. The relinquished tenement falls within the Sandover River (SF53-08) 1:250,000 and Gordon Creek (6354) 1:100,00 sheets. Access to the tenement areas is via station tracks off the Sandover Highway which runs to the northern of the tenement. The tenement is crossed by a number of station tracks. The focus was on identifying possible kimberlite targets in the presence of significant intrasedimentary background noise due to maghemite channels, areas of ferricrete, clay-pans and sinkholes and cultural sources. The altimetric DTM and radiometric data were used to assist in anomaly screening. Identifying possible kimberlite magnetic anomalies in an area of extensive drainage and palaeo-surface related magnetic anomalies is difficult due to a high degree of anomaly overlap as well as interference from anomalies due to shallow basement rocks. The relatively wide line spacing of 400-m limits spatial resolution of small sources as small kimberlites located between flight lines may not be detectable or produce only weak magnetic anomalies with magnetic attributes similar to sinkholes etc. A regional aerial photography interpretation study was undertaken by Dr. Nick Lockett of Nick Lockett & Associates Pty Ltd, Perth to identify possible outcropping manganese deposits and any potential geomorphic anomalies that may be related to possible intrusive pipes. No anomalous areas were defined within the relinquished tenement.
