Mineral resource potential and geology of Coronado National Forest, southeastern Arizona and southwestern New Mexico

Effect of size-biased sampling on resource predictions from the three-part method for quantitative mineral resource assessment—A case study of the gold mines in the Timmins-Kirkland Lake area of the Abitibi greenstone belt, Canada:

“…Size-biased sampling is not taken into account by the three-part method, so it may adversely affect its resource predictions. Although several researchers have acknowledged this potential problem (Bultman and others, 1993;Harris and Rieber, 1993, p. 38, 144-146, 150, 304-309, 508;Bultman and Gettings, 1996), there are apparently no published investigations of it. Thus, these effects are investigated by conducting a case study involving gold mines in the Timmins-Kirkland Lake area of the Abitibi greenstone belt in Ontario, Canada.…”
