De Grey Mining Limited (ASX:DEG) is undertaking a heritage survey over three conglomerate gold targets in the Pilbara region of Western Australia.
The on-ground component of the survey at the Loudens Patch, Jarret Well and Steel Well targets is expected to be completed in the next week.
Results are expected to be reported within a month of the survey being completed.

Pending a successful outcome, De Grey then expects to begin initial earthworks and bulk sampling programs with Loudens Patch the first priority.
Earthworks along the 1.4-kilometre Loudens Range are expected to expose the conglomerate horizon at specific locations.
These include at the base of the Mt Roe Basalt and across the stratigraphic horizons at Jarret Well and Steel Well.
Earthworks program approved
De Grey has received approval for a works program that will provide for total earthworks disturbance of 7,800 tonnes across the targets which will provide for suitable bulk sampling.
Detailed mapping is expected to provide a better understanding of the overall geology of the sequence, alteration and possible controls on gold mineralisation.
Bulk sampling planned
The next stage will also include detailed on-site bulk sampling, which De Grey intends to start immediately after approval is granted.
It will include on-site crushing and processing to provide a rapid visual assessment of gold content.
