Hi Johntie, I posted this yesterday in the volcom thread but it may help you crunch numbers, I've come to my conclusions from this info and other info which can be found around 2015/16 in relation to predicted revenue. If you have the time to sift through you may find it valuable. Remember this is pre MCL info:

"The company is now upgrading its exploration target to a whopping 300 million tonnes, but the existing 30 million tonne DSO already supports a major bauxite export operation. Queensland Bauxite says it will look to initially ship 5 million tonnes per year, with
revenues of between $200 million to $300million each year, based on current bauxite prices. (Note - 2014 article)
"Direct Shipping Ore (DSO) generally means that the company can just dig the minerals out of the ground and ship them to customers, with very little need for processing. That should mean low production costs, and potentially, substantial profits.
Surface deposit bauxite mining is reported to cost around $10 a tonne before transport and port costs.
Bauxite prices have surged to around $60 a tonne recently, after Indonesia implemented a ban on exports of the raw commodity in a move designed to encourage producers to process the raw material at refineries in Indonesia."
