1. For drill hole location, see Map 2.04.6-1, Geologic Cross Section and Sample Locations
2. SD -Standard Deviation
3. AP -acid potential, NP -neutralization potential, ABP -acid-base potential; Units are tons of CaC03
required per acre furrow slice; AP and ABP were calculated predominatently from total sulfur. Pyritic
sulfur values were utilized to calculate AP and ABP whenever sulfur fractionation analyses were available.
