<br /> Notes:
<br /> 1.The average total sulfur,sulfide sulfur,and total carbon for the anticipated mined materials were provided by CC&V.The average AGP,ANP,and NNP for each rock-type group were calculated
<br /> using the provided total sulfur and total carbon values.
<br /> 2.The generic Precambrian and biotite schist/gneiss rock-type groups were combined into one rock-type group for the analysis in this report because they share similar geologic and acid-
<br /> generation characteristics,and as per CC&V,three WRCS samples appear to be a mixture of generic Precambrian and biotite schist/gneiss rock-type groups.
