So in simple terms, Gneiss is high grade rock, in temperature. So what does the temperature actually mean? Is finding a Gneiss a good thing?
So Veins are very good. Typically where you find the higher grade mineralisation. A stringer, is good to find, but because it's a 'discontinued' vein...it means that it's separated from the vein. So that means, you need to find the vein? Is that correct.
So a footwall is a kind of structure which acts a 'hold' for the mineralisation body.
