VTEM™ is widely considered the best helicopter borne TEM geophysical system for detecting and imaging massive sulphide deposits with notable successes including the discovery of the Mallee Bull deposit in the Cobar Basin (see reports by Peel Mining, ASX:PEX), and the recent Artemis discovery in Queensland by Minotaur Exploration (ASX:MEP). The VTEM™ system is flown using a helicopter that tows a powerful electromagnetic (“EM”) transmitter and receiver which can detect conductive massive sulphide mineralization.
Following completion of the survey in June, preliminary VTEM™ data was processed line by line comparing early, middle and late-time EM decay responses to identify potential bedrock targets. Throughout the survey areas two targets of high significance plus a further 27 second-order targets were identified from the VTEM™ data.
