Mineralization is a tabular ore body. Ore control was faulting, shearing and igneous activity. Ore concentration was oxidation at near surface. Alteration was minor sericite along vein walls.
Area structures include veins that trend NE and dip at low angles, usually less than 40 degrees. Foliation in Precambrian metamorphic rocks trends N10E to N25E. Local granitic rocks are unfoliated.
