Volumes shown are bank cubic yards. <br />Bulking factors of 20% for unconsolidated overburden and 50% for waste rock were used. The total <br />volume of loose cubic yards placed on the reclaimed surface is 20,500,000. <br />The maximum acreage disturbed at any given time (year 3) is 95 acres. The average annual acreage of <br />disturbance over the 25-year mine life is less than 65 acres. <br />L^ A G R A <br />Eer[h & Envrronmente/Group <br />
