These are only interim forecasts for Q2 as we've got nearly another three weeks of price/exchange changes.
Average sales price rec'd: US$127/A$194/t
Unit cash operating cost: A$146/t
Concentrate production: 650kt

Nothing's permanent in life and unit costs are a product of the amount of production - Q1 had the yearly maintenance 10 day shutdown so production down & unit costs up - we should always be looking at the total costs rather than unit costs, just like we should be looking at the total sales revenue rather than average sales price.
I have used the same total Mining & Processing costs in Q2 as were incurred in Q1 - namely $95mil. Total sales revenue in Q2 $113mil (this can change by +/- 5% between now and 30Jun) assuming no additional ships to the number I already know about(with still two to arrive).
