The mineralized formation appears to be a compact, fine-grained sandstone or sandy slate impregnated with Cu & Fe. It dips SE but the strata are much broken and disturbed. Principal mineralization is in streaks along joint planes that develop into nodules and pockets. Local rocks include rocks of the Franciscan Complex, unit 1 (Coast Ranges).
