VLF surveys were undertaken to identify conductors within graphite mineralised areas around and between old adits and shafts. All survey areas contain old graphite mine shafts, adits or pits.
The VLF survey employed a Geonics EM-16 receiver, using the VLF EM signal transmitted from the Northwest Cape (NWC 22.3) VLF transmitted tower in Western Australia. The VLF survey results suggest the presence of untested graphite mineralisation. The length of the interpreted conductors are often longer than the extent of mine workings, indicating the mineralisation may extend well beyond the areas of historical mining.
Several conductors detected in the VLF survey blocks have no historical mine workings, and may be related to untested graphite mineralisation under cover.
