The area of the May Alice is underlain by basalt and andesite of the Eocene Marron Formation, Penticton Group. Sedimentary rocks of the Triassic Brooklyn Formation and the Devonian to Permian Knob Hill Group are mapped in the region. Property descriptions indicate that besides the intermediate to mafic Marron volcanics; limestone, conglomerate, arkose, sandstone and minor tuff are also present.
