The Borrow Pit is immediately east of the <br /> London Butte Portal south of the London Mine. A DRMS 110D Permit covers a portion of the <br /> London Mine. Historic disturbance covers a significant area around the borrow pit and historic <br /> mining disturbance exists within the permit area within the fat area immediately north of the <br /> London Butte Portal. <br /> 2. Site Geology <br /> Site geology within the permit boundary is limited to disturbed mining ground and rock glacier. <br /> The rock glacier is formed from Precambrian biotite gneiss east of the London Fault.
