[QUOTE="Zengeo, post: 440466, member: 9979"] Oh yeah. Many a man has lost a pot of gold chasing gold. Ben just asked for general rule, so I gave him one. Then a bit more info on the subject of grade. If a solid bunch of assays don't come back with high enough grade, don't even think about it. In high grade narrow vein orebodies the distribution of gold is typically 'nuggetty', not meaning there are nuggets everywhere, a term meaning you could take two samples right next to each other and one will come back at 50g/t. Woo hoo! But the one right next door comes back at 2g/t. Bugger. Hence the average of grades. (There's a lot else to do on that point but too much to go in to) And as Goldielocks pointed out, there's a hell of a lot more to it than just grade. The devil's in the detail and there are a lot of moving parts, as well as a lot of other sayings I'm sure. You need to be totally on top of all of it and have solid confidence in your numbers, on paper, before you even think about actually mining. But it can be done. Rios is doing it :Y: [/QUOTE]
