Comments
Comment (Location): ABOUT 1.8 KM WNW OF GOLDBERG RESERVOIR. ; INFO FROM LAND.ST :(1958)
Comment (Workings): THE ORE DEPOSITION IS ASSOCIATED WITH THE INTERSECTION OF THE MOUNTAIN CHIEF FAULT AND A MODERATELY DIPPING BEDDING-PLANE FAULT. OTHER ORE SHOOTS WERE MINED ALONG THE BEDDING-PLANE FAULT AND WERE FORMED BY AN IRREGULAR REPLACEMENT OF A FAVORABLE BED IN THE LOWER PORTION OF THE GASTROPOD LIMESTONE.
Comment (Geology): THE ANTICLINE HAS A NORTHWARD TREND AND PLUNGE.
