The team are pinning their hopes on the new hopper, as the more ground they can move, the more chance there is of finding big diamonds. The hopper is eventually completed and it is tested for the 1st time. But it's not long before it is clogged and has to be shut down while they find the blockage. Peter and Rob are concerned about leaving Warren behind unsupervised, but they have no choice. Kim goes through the backlog of bags and finds a small two carat diamond. With most of the investors away on business the mine is being run with a skeleton crew. Tensions rise as Alan's hasty approach to sorting the bags is not appreciated by Kim or Warren. There is a massive confrontation between Alan and Warren. Alan is frustrated by delays with the hopper. Friction between him and Warren is growing and frustrations boil over.
