[QUOTE="user 4386, post: 633786, member: 4386"] It is all relative, but actually it is more than 6000 km to the centre of the Earth, but essentially all economic gold was deposited in the top 15 km (not all we can get to, but probably nearly all that there is). We mostly mine the top 1 km of that (max 4 km in Western Deep Levels near joburg). [/QUOTE]
