Lots of complexities to bring this back into production from the 1990s Denehurst operation, I found this report written in 2001 that predates the 2003 bushfire that destroyed all surface infrastructure/offices/core farm, had to be pretty comprehensively redrilled after the 2003 fire.
https://www.geg.org.au/files/stockman/ML1865_G31794_200110_ausminex_feasibility_studies.pdf The 2001 report makes for interesting reading because of the number of different mining methods that might have to be used to extract some of the resources. Below are the only 2 photos I could find of the short lived Denehurst operation in the late 1990s, none of this is there anymore obviously.
Looks like a permitting nightmare to me. Sure they have some granted mining leases but there will be a lot of approvals required and issues with the legacy tailings dam to sort out.
On the plus side the resource looks very high grade, and being VMS there will undoubtedly be many other small orebodies hiding out there that haven't been found or haven't been drilled properly yet.
