copper price, page-12

"We know the 30 million tonnes of ore are to be excavated in 6 years and that the crusher is capable of crushing 5 million tonnes a year."

No. You don't know that. The crusher is rated at 3MT per year.

"Now if the crusher does crush 5 million tonnes a year, then there would be a greater return from the native copper in that 6 year period."

Even if the crusher could crush that quickly, the triple handling of the ore would more than cancel out the profit from the 0.17% NCu that it MIGHT be possible to recover, not confirmed yet and which, in any case, is only in the shallow part of the ore, not the full 30MT so you are wrong on two, possibly three counts here.

"If the crusher only crushes the 3 million tonne a year from what comes out of Las Minerale and Rocklands South as originally planned, there remains spare capacity of 2 million tonnes per annum for use with the mining of Wilgar"

It is a 3MTpa crusher.

IT IS A THREE MILLION TONNES PER YEAR CRUSHER.

As M&G say, a fool leaves his money in CDU.
