200 acres. In addition, there are many small disturbed sites within <br />the tailing basin, most of which will be covered with tailing by 1483. <br />Therefore, at this point in time, the Company claims an estimated <br />disturbance of 300 acres in the entire 1,314 acre tailing deposition <br />area corridor. <br />Tailing revegetation research indicates that tailing can be <br />amended to successfully support vegetation, and, with maintenance <br />fertilization, eventually develop into a mature soil supporting self- <br />sustaining vegetation. Still., revegetation of tailing is :zot a <br />desireable approach if there is a viable practical alternative. The <br />tailing area at Henderson will be revegetated with the aid of topsoil <br />stockpiled from within the tailing basin. <br />Reclamation technology will certainly evolve through the <br />next 30 years (and we will certainly adopt the most efficient techniques), <br />but the presently planned sequence for revegetating the ta:Lling to <br />open forest is: <br />1. Apply approximately two tons of course lime:>tone <br />per acre as insurance against long term oxidation. <br />2. Cover with approximately one foot (6"-18") of topsoil. <br />(Topsoil alone will significantly reduce oxi.dation.) <br />3. Spread and mix in 100 pounds of 0-46-0 fertilizer. <br />4. Drill seed mixture at 20 pounds per acre. (The normal <br />broadcast seeding rate is 40 pounds per acre:. Drilling <br />provides similar results at one-half the rage.) <br />5. Follow with evergreen seedlings and transpl«nt mixture <br />phased one year after grass, in sequence, ors each <br />revegetated area. <br />9-14 <br />
