so Lincoln's game plan is refined to concentrate grade only and ship in bulka bags, most likely in 5,000t parcels from Port Lincoln. A bulka bag of course is much heavier than 25kgs and I suggest for this method of shipping the bulka bags would be largest they can be 2,000 - 2,500 kgs each.
the bigger the bag the better the productivity in handling.

it is a low pitch play, dig it out, minimal purification [by graphite standards] and ship it out for someone else to value add.

good luck to them but its not for me

I will stick with vxl, even though timelines blown out by at least 6 months
