| Deposit | ALTHOUGH NO DETAILS OF DEPOSIT ARE AVAILABLE, IT IS PROBABLY SIMILAR TO THAT AT GRAPEVINE MINE, PRINCIPAL VEINS LIE IN JUNCTION RANCH FAULT ZONE CLOSE TO ITS INTERSECTION WITH CHERRY GULCH FAULT. VEINS STRIKE NW AND DIP 20 TO 60 NE AND CUT PREDOMINANTLY BIOTITE-QUARTZ GNEISS. GRAPEVINE WORKINGS MAINLY ON EAST VEIN AND SECONDARILY ON TARGET VEIN, BOTH VEINS APPARENTLY BRANCHES IN FOOTWALL OF WNW-STRIKING FAULT. LENTICULAR URANIUM ORE BODIES ARE 1 TO 2 FT WIDE. PITCHBLENDE COATS FRACTURES AND ALTERED BRECCIA FRAGMENTS. STRUCTURAL ZONE ON JUNCTION RANCH FAULT CAN BE INTERPRETED SIMILAR TO BRECCIA REEFS IN RALSTON CREEK DISTRICT TO NORTH. |
