Dec 07, 2005 (A Mitchell) - The 4 Couchenour - Willans - Selco drill holes intersected varying concentrations of sulphides in a mixed sequence of black argillaceous sediment and intermediate to felsic metatuff. Sulphide concentrations up to 23% including up to 2% sphalerite and 3% chalcopyrite are noted in the drill logs. The geophysical anomaly associated with the sulphides trends east with a strike length of about 800 m.
