The Rising Sun claim (L.722) is located in an area of skarn- type mineralization. The area is underlain by the Upper Triassic Quatsino and Karmutsen formations(Vancouver Group). The formations are in fault and/or intrusive contact to the immediate east with intrusive rocks of the Juro-Cretaceous Coast Plutonic Complex.
