significant sulphides, page-8

I'm not so sure Biggle.

You've said 100kg of concentrate per 100 tonnes of feedstock, which again is the same as 1kg of concentrate per 1 tonne of feedstock.
So 30,000 tonnes of feedstock = 30,000kg of concentrate, not 3,000kg of concentrate.
So you can multiply the rest of your equation x 10.

They should be able to process 120k tonnes in 240 working days at 50tpd, so that's a full year's production.
So does that mean $36M at $700 per ounce? Depends on the recovery rate from the concentrate I suppose.

It's far too late for this here in NZ. We'll let the market tell us tomorrow how right or wrong we are.
Good luck.
