cdu's mined copper reserves, page-9

700,000 tonnes of ore pulled out of the ground, but no holders know what copper is in that tonnage.

Is this the new blindfold technique where holders are kept in the dark about their very own mine?

Maybe the overall copper percentage isn't that great? Why else keep the number under wraps? Do they need a decent amount of copper from the high grade zone to bring the percent up to a respectable number?

Always interesting. Always a plot in progress.
