July 16, 2012 (Source: Lincoln Minerals) — Airborne electromagnetic (EM) surveys have commenced over Lincoln Minerals Limited’s (“LML”) Koppio-Kookaburra Gully and Cockabidnie-Campoona graphite projects on Eyre Peninsula in South Australia.
The EM surveys are expected to be completed within seven days subject to weather conditions plus another 4-6 weeks for processing. The data and maps will facilitate detailed mapping of the highly conductive graphite horizons to delineate additional exploration drilling targets.
The Koppio-Kookaburra Gully survey is located on southern Eyre Peninsula 35 km from the port of Port Lincoln and will be a detailed 100m line-spaced survey over the historic Koppio Graphite Mine and Kookaburra Gully graphite deposits. Bulk samples of flake graphite from these two deposits are currently undergoing metallurgical testwork in Germany and Austria but have been assayed at grades ranging up to, respectively, 32.0% and 28.6% TGC (graphitic carbon; Table 1).
The Cockabidnie-Campoona survey is located northwest of Cleve on central Eyre Peninsula and is a larger 400m line-spaced survey covering the entire exploration license EL 4883. It is supported by a South Australian Government PACE grant and covers the extensions of Archer Exploration Limited’s (“AXE”) Campoona and Sugarloaf Hill EM nomalies and Monax Mining Limited’s (“MOX”) Jamieson Tank EM anomaly.
