Deposit TWO SMALL OPALITE BODIES, ONE 60 X 20 FT. AND THE OTHER 80 X 100 FFT. CINNABAR IS DISSEMINATED IN THE MOST OPALIZED ROCK WITH LITTLE CONTINIUTY. ENTIRE TOP OF HILL APPEARS TO HAVE BEEN A HOT SPRINGS CONDUIT, APPARENTLY CONTROLLED BY A N30E SHAR ZONE NOW OCCUPIED BY SOFT LEACHED ROCK WITH FLUFFY SILICA IN OPEN SPACES. SOME HG MINERALS (HGCL AND CINNNABAR) ON FRACTURE COATINGS, AND CLEAR SILICA COATS THE HG MINERALS. AREAS OF SOFT FLUFFY SILICA AS PIPES AROUND OPALITE BLOCKS.
