In relation to my estimate of $64mil for Mining and Production costs, I have loaded an additional $4mil into that figure to cover maintenance work on the Port Latta jetty that I am guessing is happening at the moment. I reached that conclusion by the presence of two Pilot vessels(not tugs) GR35 & GR22 that have been at Port Latta over the last month or so and I note the Corporate Update dated 2Mar18 stated in the last sentence on pg1 "and structural refurbishments of key infrastructure at Port Latta, including the pellet plant and the offshore structure estimated to be approximately $8 million."
But at the end of the day, that's only a guess on my part. Just another 'dartboard stuff' prediction as is the Concentrate/Pellet production figures that will effect a lot of the other figures such as unit operating cost and pellet stockpile. Unfortunately you can only put so much science into these predictions.
