| Lamprophyre-Unsubdivided | 4 | Carbonated | Breccia | Footwall |
Dec 07, 2005 (D Guidon) - Rocks were mapped as wackes and congloerates by Thomson (1947). A series of veins strike about 210 and dip steeply west. The footwall is either a highly altered carbonated conglomerate or a caronated pebbly lamprophyre. A grey porphyritic? rock lies below the lamprophyre.
