Lake Lefroy Nickel Prospect

The Kambalda region is prospective for both orogenic gold and massive Ni sulphide mineralisation and has a history of extensive production from mines such as the Long (200,000t Ni) and Beta-Hunt (nickel) (35,000t Ni).

The project area is located over part of the Aztec Dome which exhibits a similar regional magnetic image to that of the Kambalda Dome. The aim of this work is to test for the presence of conductive nickel sulphide mineralisation associated with ultramafics units around the dome.

A SQUID MLTEM ground geophysical survey has been done so to define nickel targets beneath the lake surface. SQUID sensor systems have become an accepted tool for ground-based TEM prospecting. A particular advantage of these sensors, compared to the more conventional coil sensors, is their enhanced conductance discrimination capabilities. This enhancement enables detection of highly conductive targets either buried beneath a conductive overburden or located close to a conductive host rock. The SQUID class of TEM sensor has been responsible for a number of major new nickel-sulphide discoveries worth billions of dollars.

This incomplete survey has already identified a number of potential nickel targets. Unusually wet conditions on the lake has hampered progress however Aragon will complete the survey as soon as practicable.
