Mining of the Johnny Lee deposit requires only a small underground operation by modern standards. The upper zone is 3,000 feet long in a north south direction, and 1500 feet wide in an east west direction. The Johnny Lee lower zone lies 1500 feet below the bottom of the Sheep Creek Valley, and gently rises to a depth of 1100 feet on its western end. The lower zone is 3,000 feet long in an east west direction. The surface opening (portal) for the 5,000 foot long access tunnel for the Johnny Lee deposit will lay on the south side of Sawmill Hill, well outside the Sheep Creek Valley and is 200 feet above the water table. This deposit hosts just under one billion pounds of high grade copper.
