mined in a manner which produces no wasterock requiring sur- <br /> face disposal , consequently surface disturbances related to <br /> mining activities are minimal and consist of surface support <br /> structures and mine supply yards at the portal area. <br /> Ore removed from the mine is transported by truck to the <br /> Mayflower Mill where gravimetric concentration and differential <br /> flotation processes are employed for extracting desired mineral <br /> content from the ore. Major products produced by the ore <br /> beneficiation process are a lead-copper concentrate, zinc <br /> concentrate, and a gold-silver amalgam. The majority of the <br /> ore processed at the mill is comprised of unmerchantable host <br /> rock which is discarded at the end of the milling process or <br /> tailings circuit. Surface disturbance resulting from milling <br /> operations consist of tailings disposal sites, the mill struc- <br /> ture, and related equipment storage yards. Mill tailings dis- <br /> posal operations are the dominant cause of affected acreage at <br /> the Silverton installation in terms of extent and intensity. <br /> The Reclamation Plan developed for affected acreages pro- <br /> posed forest habitat reflecting floristic community structure <br /> of adjacent undisturbed lands as the final objective. Forest <br /> habitat was selected as the optimum reclamation goal for dis- <br /> turbed lands upon considering perpetuity requirements, economic <br /> feasibility and aesthetics . <br /> Affected lands at the site vary in elevation from 9,400 to <br /> 12,200 feet. Due to the inherent variability in topography and <br /> climatic factors among disturbance areas, the types and extent <br /> of microsites for vegetative establishment are diverse. In <br /> general , however, disturbance areas are characterized by the <br /> Page 2 <br />
