Satelite View

Comments

Comment (Geology): THIN-BEDDED LIMESTONE STRIKES NORTH AND DIPS SOUTHEAST AND IS INTERBEDDED WITH SHALES AND VOLCANICS. THE GRANODIORITE STOCK INTRUDES SEDIMENTARY ROCKS WEST OF THE MINE.

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH M242839, WHICH HAS BEEN DELETED.

Comment (Location): ON EAST FLANK OF TOBIN RANGE ON STEEP RIDGE NORTH OF MORNING VIEW CANYON. . INFO FROM LAND.ST :(1972); PREVIOUS QUAD DESIGNATION = BUFFALO SPRINGS 1:24000

Comment (Deposit): SCHEELITE OCCURS IN LENSES OF SILICIFIED LIMESTONE CUT BY NUMEROUS QUARTZ STRINGERS, 1-24 INCHES WIDE AND UP TO 50 FEET LONG. TWO LENSES YIELDED 1 TO 6 TONS OF SORTED HIGH GRADE ORE EACH AND TWO OTHERS YIELDED ABOUT 100 TONS ORE THAT CONTAINED ABOUT 2.5 % WO3. MINOR PYRITE AND MOLYBDENITE ARE ALSO PRESENT. JOHNSON AND BENSON REPORTED A 1 FOOT SAMPLE FROM NO. 1 ADIT ASSAYED 4.20% WO3 AND A 0.7 FOOT SAMPLE FROM NO. 2 ADIT ASSAYED 5.12% WO3.; MODEL NAME COULD ALSO BE: W VEINS.

Comment (Workings): 2 SHORT ADITS AND SEVERAL PITS.

Comment (Production): JOSON AND BENSON REPORT THAT 33 TONS OF SELECTED, SORTED ORE, CONTAINING 1.69-11.1% WO3 WERE SHIPPED (DATES UNSPECIFIED).

Comment (Development): BLOSSOM OPERATED THE MINE DURING 1941-1943 AND 1951-1954.
