The Mt Isa facility is an asset of the company and a very good acquisition IMO. It has scope to be used for many years to come.
The transport of the cores from site to Mt Isa was done in a very cost effective manner with logistics provided by the Landowner.
I expect for the return trip from Mt Isa that the Landowner would be bringing in supplies for their needs.

Paying a third party to dead head a truck empty from Mt Isa to pick up cores would be adding to costs, same as paying a third party to process the cores. Yes it would have sped up the process, but at what cost? The prospective targets have been there for a while and are not going anywhere.
