Statistics for Au and Ag assays by interpreted lithology (Figures 17-1 and 17-2)
indicate that vein is much higher grade than the other lithologies (length-weighted
average in vein for Au is 20.7 g/t and 224.1 g/t Ag). Grades are variable as shown by
the coefficients of variation, 2.4 for Au and 3.2 for Ag. Assay length for samples tagged
as vein is also variable, ranging from 0.03 to 3.6 m with a mean of 0.78 m
