Bulldozer work will finish grade the rock talus slope as necessary and will <br />configure a large berm for rock catchment at the base of the highwall contact. <br />GOLD HILL/SENATORS HILL CONTACT HIGHWALL <br />The highwall area directly below the Gold Hill working level is a vertical rock face of gypsum <br />and anhydrite rock which were active mining faces. The vertical face area extends for almost <br />one quarter of a mile along the #3 bed contact (mid-way between the evaporitic section) along <br />the strike of the ore body trending in a southeast/northwest direction. The height of the vertical <br />mining face ranges from 50' to 75'. The tonnages blocked out on each section are for drilling <br />and blasting to result in final slope of 1:1. <br />Section 1300 4000 tons <br />Section 1400 5000 tons <br />Section 1500 5000 tons <br />Section 1600 18200 tons <br />Section 1700 6400 tons <br />Section 1800 9600 tons <br />Section 1900 11600 tons <br />
