1FOr drill hole location, see Exhibit 6-4. The ~~r/~~ fix was gmitted from the Sample Site ID in this table. No underburden samples were collected
from Sites 2312E, 30488, 30498, 3050B, and 30518.
2The following abbreviations are used: X = percent, mmh o/cm = millimhos per centimeter, meq/l = milliequivalents per liter, ppm parts per
3million, and NA = no analysis.
4Velues were adjusted for less then values acc Hilton (1984),
SUnit is tons calcium carbonate equivalent per 1000 tons of overburden.
All mean values were less then the detection limit of 0.01 for selenium and 0.6 for molybdenum.
