Whitelaw Fault Lynchpin, page-56

I think people don't realise the importance of Tandarra wrt CYL / GEV being able to exploit 4 Eagles.
The Murray basin sediments cover both properties, about 20 to 40m deep at Tandarra and 80 to 140m deep at 4 Eagles.
The sediments are very fine grained, they consequently have a low angle of repose when you excavate. The issue is compounded by saline ground water although its apparently not such a problem at Tandarra as at 4 Eagles. Probably a consequence of the additional depth. CYL have publicly released a conceptual pit design for Tandarra, don't be surprised if this turns into the portal for the more Northern prospects as it will limit their issues (and costs) getting thru the fines and the salt water. Tandarra is the lynchpin of the Whitelaw IMO. DYOR.
