The property is underlain by a northwest striking sequence of Paleozoic Sicker Group, Myra Formation volcanic and sedimentary rocks which are overlain by limestone of the Buttle Lake Formation. To the south these rocks are in contact with the Paleozoic to Mesozoic West Coast Complex amphibolites, hornfelsed volcanics and diorites. Locally, feldspar porphyritic dykes (Tertiary?) intrude the Sicker Group volcanics and sediments. A north-south trending regional fault occurs subparallel to a major creek on the Good Friday claim. A gold bearing arsenic showing occurs in a shear zone along this fault. Sulphides +/- anomalous gold values and copper occur in quartz veins, shear zones, skarns and altered volcanics.
