Abstract

Very low-grade, uneconomic uranium mineralization occurs over a large area of northern Nova Scotia. It is associated with chalcocitized carbonized plant fragments that occur in gray continental sediments of the Pictou Formation (Upper Pennsylvanian). Typically the plant fragments occur in conglomerates, grits or arkoses that fill stream channels in underlying red mudstones. The copper and uranium mineralization are closely associated, are related to the presence or absence of coaly fragments, and are of supergene origin. The deposits investigated proved uneconomic, but are similar to those of the Colorado Plateau region of the southwestern United States. Some 26 shallow drill holes totalling 3,089 feet have been drilled to investigate the deposits.
