"According to those speculations, not only could the present plan (for conventional mining through horizontal (stoping) of what resource is known to be there) be expanded to produce an increase to 3m oz over a 11 year life, but the additional resources now being found in almost every direction around the high grade deposit delineated so far could lead to a new phase of mining of the deeper, more extensive, but lower grade material there.
This will by a different method though – block caving, initially more expensive but cheaper in the long run – to extract the slightly lower grade ore – and can only start from nearly 10 years time to last for another 18-20 years.
This scenario, as I say, is speculation by the brokers’ analysts (most seemingly with geology or mining qualifications but not necessarily mining experience), but have not been commented on by Newcrest, who will actually determine what will, or won’t, happen so far ahead."
Nonsense! Sandeep Biswas stated, well over a year ago now, that it was clear that different types of mining would almost certainly be needed at Havieron. It's become significantly clearer now too, with added drilling since!
