Nickel averaged 14.00 ppm (± 9.15 ppm) in West Virginia coals with a histogram showing a near normal distribution with a tail toward higher values and a maximum value of 99.9 ppm in a bench of the No. 5 Block coal.  Nickel correlated poorly with ash yield, moderately well with cobalt (Co), and less so with vanadium (V), gallium (Ga) and lead (Pb).
