Ann: Nifty Copper Operations Update, page-4

There is some promising discussion of costs. Hard to quantify but here:

Improved mill output – Historically the Nifty Mill has produced a 22% copper concentrate whichover the last two milling campaigns has increased to 26% copper. Each one percent increase inconcentrate grade equates to an approximately $1.0 million annual saving in costs to the business;

$4 million saving?

Fleet cost seems to have reduced from 700k/month to 150k/month as at 1 July 2019 (So already factored)

$6.6 million saving?

So $10.6 million quantified cost savings. But has a lot of this already fed into the FY19 annual numbers? I noticed the costs came down a bit - and more dramatically if you take into account the increase in 'sustaining capital' (not clear what this is.. wonder why it is recurring?)
