I think $4-$6m for Q4 is probably reasonable (before corp G&A). The trick is not so much working out absolute costs - which typically track at A$40m per quarter.. it's working out the denominator (tin production) and that can vary quite a bit depending on how productive the mining operations are, the tin grade & recoveries. It's anyone's guess as to how mining has performed this Q - perhaps @Bilge can shed some colour.. ultimately the mine design and the new areas being developed into should yield much higher production and with that cash flows still attractive at a A$32.5k/t price
