The McKay Hill project is located within slope-to-basin strata of the Selwyn Basin. McKay Hill sits within the Dawson Thrust sheet, which is bound by the Dawson Thrust to the northeast and the Tombstone Thrust to the southwest.
McKay Hill has historically been explored for Keno Style polymetallic Ag-Pb-Zn veins hosted in greenstone sills intruding Hyland group slates, quartzite, conglomerate and limestone. To date, 17 veins have been located and identified, predominantly within the central claim area. The mineralization is considered to be typical of clastic metasedimentary rock-hosted Ag-Pb-Zn veins such as those at Keno Hill.
