<br />• <br />2. PROJECT DESCRIPTION/MINING PLAN <br />The scope of the Henderson Project can best be understood by <br />separately discussing its three major components: (1) the mine site, <br />(2) the ore-haulage railway, and (3) the mill, crusher, concentrator <br />and tailing deposition site. <br />2.1 MINE SITE <br />The mine (Figure 2-1) is locz.ted on the north side of Red <br />Mountain near the confluence of Butler Gulch and the West Fork of <br />Clear Creek. It is approximately nine miles west of Empire, Colorado, <br />in Clear Creek County on the eastern slope of the Continental Divide. <br />The 1.5-mile access road to the mine site leaves U.S. Highway 40 at <br />• the small village of Berthoud Falls, Colorado. The elevation at the <br />mine site is about 10,400 feet. <br />More than 300 million tons of 0.49 per cent molybdenite ore <br />are located about 2,200 feet beneath the base of Red Mountain. The <br />ore body is elliptical in plan (3,000 by 2,000 feet) and varies <br />between 400 and 1,200 feet thick. <br />Access to the mine is gained by a 28-foot diameter vertical <br />shaft which is 3,100 feet deep. Two other shafts service the venti- <br />lation requirements for incast and outcast air. 2,500 feet of hori- <br />zontal drifts at the bottom of the shafts provide access to the ore <br />body. A highly mechanized panelcave system of mining is being used to <br />work toward an initial production of 30,000 tons of ore per day by <br />1980 with the capability to expand to 50,000 tons per day.
