RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:Let's speculateBlue,
Salamis said and you quoted: "he said. “There’s
no way to know they were there until you drifted into them (underlined mine), because they have limited strike and volume. When we drifted into one, the mine captain would come down, seal it off, put up a big padlock door and lock off the stope. You can literally make up a month’s work of production just from one of these stopes by sending a guy in there with a bucket and a hammer.”
True, but grades as indicated by the tiny drill cores of over 2 ounces/tonne (~62gpt) over some m length look quite good (OK, let's not call those jellewery boxes), but 2 truck loads of that stuff would fetch $1M...no chump change. If they hit a few with grades of 459 gpt/2.2m (i.e. ~15 oz/tonne, like hole 261) then 3 holes would yield 15/2 x $1M = $7.5M. May be a guard would ride shotgun with the truck driver.
I would imagine that facing with a wall (say 150m x 70m) as shown in C2 x-section. The bulk sampling operation is kind of like trench sampling. They would have to devise a systematic scheme to collect the samples (every 10m to drill so bid a hole and how deep)
