Ahhhhh!  We dont need to do it by hand or shovel.  There is another way to get that ore to surface via the use of Gophers.  OK, first we get a stretch of land that needs to be cleared off of too much vegitation, fence the area in and whenever we need one just put em on a leash and take em to the spot where we would normally put down a drill.  My childhood was on a FARM and here is where i learned about Gophers.  They can get the job done mark my words and all we will need todo is take em back to the fenced in corral at the end of their shift and let em chow down sleep and be ready for the next days digging.  Ingineuity,, works everytime,, use your brain not your body!
