Resource Update, page-27

If I’m not mistaken at one stage (possibly around the 2017 scoping study) AML were investigating whether they could use the Century infrastructure for Walford Creek (considering they have a pipeline and existing port infrastructure at Karumba), however this didn’t eventuate.

The Isa route would certainly be the most straight forward with the current infrastructure. Karumba option would likely require infrastructure like a slurry pipeline & barge (similar to Century) which would add to the CAPEX costs but save quite a bit on transportation. Given the volumes they are looking to produce Karumba is unlikely imo. That said if the resource with additional drilling over time grows to say 2-3x and they can scale up production on a similar scale then it may be worth looking at again.
