RE:RE:RE:This Is Total B.S.marnesue-It means what it says. Commercial operation will happen in 2017 after commissioning.There is a difference between "substantial completion" and operation at rated tonnage for an agreed period of time. If one component of a complex operation does not perform as promised-then the supplier will normally work with the contractor, engineer and owner to rectify the deficiency. When all efforts have failed then there is recourse for the owner to demand replacement equipment or compensation but if this component is crucial to obtaining the nameplate rating of the entire mine it could have an effect on complete commissioning. I would stop short of placing blame at this point as there has been no news from the company saying there is a problem, but I would expect that modified operations are already underway and the bottlenecks are being addressed. Patience Patience -sell if you want to but I think that this is a well managed company and in general have under promised and over delivered.
