RE:RE:RE:Deepest open Pit 1,200m I agree. Over 2.3km, 3 (maybe 4) shafts should be sufficient. Get in there and go chase the quartz veins. By the time it is done, it will look like an ant colony...

I envision three shafts serving a maze a tunnels following the veins. This kind of mining has worked well for thousands of years (ie. Laurion, Greece). It will work well on the rock, although slaves will have to be replaced by robots.
