My guess is that it relates to the outstanding assays. These might give a preliminary tonnage estimate for Rockhole bore, ore characterisation results and confirmation of mineralisation in 3 of the other gravity zones they were meant to have drilled in July.

The ore characterisation may confirm that the overburden is saleable, plus the ore characterisation results have been previously mentioned as the first step to getting serious negotiations with Chinese steel mills under way.

I don't believe it will relate to rail infrastructure as there is still not enough information about how much ore is to be transported. Additionally, if the overburden is saleable, won't that also need to be transported to port via rail? Does this mean that it becomes up to 10MT iron ore plus overburden that needs to be moved by rail? If so, I can't see BHP being all that happy giving up that much of their rail capacity and I think the spur line to Cloud Break is looking more likely.

It sure must be a significant announcement to be made though - hope it's positive.
