General comments

Subject category Comment text
Deposit IN MINOR SHEAR ZONES IN THE DOLOMITE AND CONGLOMERATE, AND AS SMALL REPLACEMENT LENSES IN DOLOMITE. SEVERAL MINERALIZED AREAS OCCUR IN AN E-TRENDING BELT; THE LARGEST AREA 300 FT X 135 FT, LENSES OF NEARLY PURE HEMATITE AND PARTLY REPLACED DOLOMITE AND CONGLOMERATE ARE INTERMIXED WITH SMALL MASSES OF UNREPLACED COUNTRY ROCK.
