The 9 May 2016 Ann tested both VBC and Collie Coal. Results were not that dis-similar by the way. Refer to this Ann herein Post #: 17712579
The issue for GPP switching to Collie Coal will cause the market IMO to just shake their heads further at GPP in disbelief (probably leading too many needing to wear neck braces for a while). The only way I can see Collie Coal working, and one been acceptable to the market, is if GPP is able to secure a portion of land within the Industrial Precinct near Collie in WA at a very low rent and access to cheap coal for that process - then the market might say yeah understand reasoning in light of management major stuff ups. Anything else is whip lash territory as the head shakers rattle into a neck brace.
