The work area lies in the lower part of the Middle Devonian Myra Formation stratigraphy on the property. The most dominant lithology is aphyric pillowed basalts which locally have cherty pillow interstices. The unit is capped by a complex of laminated cherts, locally jasper and/or magnetite-bearing, and mixed basalt and chert tuffs and lapilli tuffs. Strong penetrative schistosity striking 330 degrees with subvertical dip and shallow plunging northwest lineation affects the basalt flows. Gold mineralization occurs in quartz stockwork and veins within pillowed basalt flows as well as pyritized chert and basalt tuff which overlies the flows.
