Grange Resources operates Savage River Mine which lies
100km Southwest of Burnie in Tasmania.
The magnetite ore body stretches 25km south of the
Savage River township ranging in thickness from 40m
to 150m. Current production is two million tonnes of
premium iron ore pellets; this is expected to rise to
nearly three million tonnes as the open cut mine extends
underground.
HMA Geotechnical was contracted to install vibrating
wire piezometers both in the open cut pit and the newly
opened underground drive.
