Grab samples from in-situ rock within the tunnels.
"Samples are taken of in-situ rock across the exposed vein in the backs (roof) of the tunnels, in conjunction with geological mapping."
Given our low cost opex and zero capex the Cu price would need to fall by a huge margin to make El Roble uneconomic and I do not see that happening.
Chile is the world's number one Cu producer, the Chileans know where the Cu buyers are.
Anyway more good news today, it certainly looks like we will be physically producing 10 000 mt of high grade Cu ore by the end of the next quarter.
A stock market is meant to be a mechanism for reflecting future earnings and prospects, I certainly agree that MNE is due a re-rating whatever happens to the Cu price short term.
