Yes @rivermore. CYL have released a conceptual pit design for Tandarra. It was on their AGM preso as well (see below). It's interesting to know it could "turn into the portal for the more Northern prospects as it will limit their issues (and costs) getting thru the fines and the salt water. It would be more interesting if Tandarra is the lynchpin of the Whitelaw. Fingers crossed.
Also, I was not aware of the issue with the fine grained Murray Basin sediments and the issue with saline ground water which would cause the pit to be a low angle of repose when you excavate. 20 to 40m deep at Tandarra and 80 to 140m deep at Four Eagles makes Tandarra the main place for open pit then. Interesting to know these. Thanks @rivermore
