Not so easy open-pitting a steeply dipping vein, is it? Big boulders of barite were easy at first, and make great pictures for websites and cartoon newsletters. But go down a bench or two, and suddenly they are finding that they are having to move 10 times more waste to get at the barite.
Oops, getting pricey to have all that equipment on-site. The burn rate must be quite impressive. Watch out, dilution coming.
