Witbank coalfield Aeromagnetic Merge Project-A Coaltech-2020 initiative

A Coaltech-2020 Geological and Geophysical Steering Committee task was initiated in 2003 to source existing<br>airborne magnetic datasets over the Witbank coalfield and to collate these into a single map. The main project<br>benefit is to provide Coaltech-2020 participants with a more global perspective by being able to trace magnetically<br>susceptible dykes cross-cutting the coalfield, from beyond their individual mining leases, thereby potentially<br>identifying previously unknown dykes in their own areas. Potential savings to mining operations generated by<br>access to such additional information may be worth millions of rands.
