Thanks banksy,

But what is the saleable product per annum based on 20-22mtpa of mining?

My understanding is that approximately half (55%) of what is mined is actually saleable due to benefication, washing etc?

Can you confirm?

$1.2 billion capital cost for an open cut operation to mine around 22mtpa and ultimately produce 12mtpa of product? Is this correct? Just seems awfully expensive for an open cut operation? An underground mine that yields around 75-85% could achieve the same result with possibly less CAPEX?

I am just looking through a few coal explorer/developers and waying up the pro's and con's of U/G and O/C operations with respect to CAPEX and ultimately OPEX.
