Voici comment la géophysique travaille à Sullivan.

The Sullivan mine, located in British Columbia, Canada, is one of the world’s largest Sedimentary exhalative (SEDEX) deposits having produced more than 140 million tonnes of ore.

A distinct, moderately positive, irregularly shaped magnetic anomaly is observed along the trend with zones of higher anomalous values.

The magnetic peak at Sullivan is due to the un-mined massive pyrrhotite replacement body and the network of pyrrhotite-quartz-carbonate veins (90% of the ore has been mined.)

Frequency-domain EM data indicate corresponding zones of high conductivity.

The profiles indicate the presence of a series of good conductors within the anomalous zone.
