Partners NORANDA, NOVICOURT and VIRGINIA GOLD MINES have completed 10 airborne MegaTEM surveys over 9,063 square kilometres in four different regions of Quebec. Cost of the surveys was about $5 million.

The unique MegaTEM technology was developed by Fugro Airborne Surveys with the support of Noranda. The system uses airborne electromagnetic surveillance to detect massive sulphide-type anomalies. It was used by Noranda in the discovery of the Perseverance deposit near Matagami, Que., in 2000. That deposit has measured and indicated reserves of 5.2 million tonnes grading 1.24% Cu and 15.82% Zn.

Noranda, Novicourt and Virginia Gold have acquired about 300 MegaTEM anomalies since the project started. Certain of them will be drilled in the next 18 months. Drilling of anomalies found during the first and second MegaTEM surveys has returned semi-massive sulphide intersections up to 20-m thick. Most of these intersections were barren to weakly anomalous, undetectable by previous airborne technologies.
