Ann: Sixth Shipment of HMC Completed at Coburn Project, page-47

Trying to envisage what the problems that they are encountering could be......
Mining "Low strip ratio, low slimes, conventional mining,
free-flowing sand, coarse grain"...... so no rocks or organics blocking up the rougher spiral distibutors.
A brand new engineer designed (what could go wrong there?) wcp.
Operates at name plate throughput...some of the time

Maybe water issues?
Gotta pump 3000tph of ore from the pit to the wcp and pump 2970tph of tails back at 25%(?) density
Then reclaim as much water as possible from the tails void.
Water loss calcs in the dfs underestimated? bores not keeping up?
