• Of this total, it is estimated that 25000 tons of rock will be drilling and shot to result in a rack <br />talus slope with catchment bemt left at the foot of the slope of the Gold Hill Highwall. Bulldozer <br />work will be necessary to configure the final catchment berm area. <br />GOLD HILUSENATORE HILL CONTACT HIGHWALL <br />The highwall area directly below the Gold Hill working area is a vertical rock face of gypsum, <br />anhydrite, and limestone rock which are active mining feces. They extend for almost one <br />quarter of a mile along the three bed contact(mid way between the evaporitic section) along the <br />strike of the ore body trending in a Southeast to Northwest direction. The height of the vertical <br />face varies from 50' to 75'. The tonnages below are those blocked out on the sections for drilling <br />and blasting of the rock to result in a rock talus slope of 1:1. <br />Section 1300 <br />Section 1400 <br />Section 1500 <br />Secton 1600 <br />Section 1700 <br />Section 1800 <br />Section 1900 <br />Section 2000 <br />Section 2100 <br />• <br />Total Tonnage <br />GOLD HILUCOPPER HILL CONTACT HIGHWALL <br />4000 tons <br />5000 tons <br />5000 tons <br />18200 tons <br />6400 tons <br />9600 tons <br />11600 tons <br />18800 tons <br />16800 tons <br />95400 tons <br />Also along this same line of direction but further north along these sections, a highwall face <br />exists on the South aspect of Copper Hill, accessible from the Gold Hill 6935' working level: <br />Section 2200 3400 tons <br />Section 2300 4000 tons <br />Section 2400 4400 tons <br />Section 2500 4000 tons <br />Section 2600 5000 tons <br />Total Tonnage 20800 tons <br />The Copper Hill Southern aspect volumes will also need to be drilled, blasted, and bulldozed to <br />result in a rock talus slope of 1:1. <br />• <br />
