No crushing is utilized in the <br />materials processing. The black sands, which coot in gold <br />and other minerals, will be removed to the gold buil ing for <br />final processing.

The initial pond will be approximately 250 fe t x 100 <br />Eeet x 10 Eeet in depth. The pond in the Soutii Central <br />Phase will be approximately 300 feet x 150 feet x 15 feet in <br />depth. <br />(8) The processing plant will be moved to Plant B ~n 1987. <br />Plant B is a three-acre area already backfilled and graded, <br />but not yet revegetated. <br />(9) Excavations of the South Central, South a <br />Phases will maintain a 200-foot buffer from the <br />Colorado Springs water pipeline.
