Previously confidential geophysical data on new target areas of mineral potential is now public information. The Ontario Geological Survey purchased airborne geophysical data of the Cobalt, Temagami South and Temiskaming areas from Falconbridge Ltd. and Spider Resources Inc. The data sets of about 19,000 line-kilometres include magnetometer and electro-magnetometer data. The Cobalt survey revealed over 140 anomalies in rock formation that may indicate economic mineral deposits. OGS officials say the acquired data complements the province's own geological survey information.
