The Buda property is underlain by diorite breccia of the Iron Mask Hybrid unit and diorite and monzonite of the Cherry Creek unit, both of the Late Triassic-Early Jurassic Iron Mask batholith. Weak disseminated and fracture-coating pyrite and chalcopyrite mineralization occurs in Cherry Creek unit diorite. The diorite contains strong north to northwesterly striking, steeply dipping fractures and exhibits K-feldspar alteration.
