An abundant amount of grey coloured, medium-grained granodiorite was quarried from a site along the northeast side of Deep Cove. No production figures are available.

The granodiorite is Early to mid-Cretaceous in age within the Jurassic to Tertiary Coast Plutonic Complex and was quarried extensively for local use as jetty rock and riprap. The grey granodiorite hosts irregular and discontinuous sheet jointing.
