Hydrogen -
He mentions the brecchia and the possibility of block caving.
The boundaries between the sulphide areas and the adjoining brecchia represent thousands of square metres, at Havieron.
So, if NCM were to mine the high-grades zones first, by stoping, as has been suggested, then perhaps the stopes could later give them access to the sides of the brecchia, over thousands of square metres.
Potentially, there could be a big saving in Capex, compared to a deposit where block-caving was used, but no convenient stopes nearby.
Do we have a mining engineer on this board ?
