As for cash costs; I presume they've gone up due to the supplementary crusher now being in circuit (ie. higher power costs).

From what I can tell, this crusher is required for the harder ore in order to maintain throughput. Hence, we may not see much more, if any, reduction in cash costs until we get the next plant upgrade to 10mtpa. Either that or higher grade ore, which doesn't seem to be on the cards at the moment.

June Quarter for the optimisation study to come out. This was already flagged in recent announcements so on target still.
