Deposit: Quartz-hematite-magnetite vein cuts granite. Vein cropping out in canyon north of adit is about 2 ft thick, lenticular with magnetite-hematite clots up to 1 ft across, 2-3 ft long. This structure projects across canyon to the SE and may be exposed in the cut directly east of the adit. Other parallel narrow veins cut the granite, and fracture surfaces of the granite are coated with fine-grained magnetite and pyroxene. The cut directly above the adit exposes a 1 to 2 ft wide brecciated magnetite-hematite vein striking N 10-20 w, 75 ne. This zone is narrow in outcrop, but appears to widen to 4-5 ft where exposed in the toe of the cut. The granitic wallrock in the vicinity of the veins is cut by numerous thin quartz-hematite-magnetite veins and aplite dikes. The granite has inclusions of fine-grained altered diorite and some metasediments.

Development: Evidence of a small amount of hand-digging at the two cuts, but no major work has taken place on this property for several years.
