Morning Star Claim

The Morning Star Claim is a tungsten mine located in Pinal county, Arizona at an elevation of 5,000 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Analytical Data

Analytical Data: UNDER UV LIGHT, ORE ALONG FAULT APPEARED IN PLACES TO CONTAIN AS MUCH AS 10%. TUNGSTEN TRIOXIDE ACROSS WIDTHS OF 0.5 TO 2.0 FT. THOUGH IN MOST PLACES IT GRADES NOT OVER 1.0 PCT. TAILING SAMPLE FROM THE RIVERA BROS. MILL SHOWED: .15 PCT MN, 91.9 PCT INSOL., 85.8 PCT SIO2, 1.4 PCT FE, 2.3 PCT CAO, .15 PCT S, 5.1 PCT AL2O3, .6 PCT MGO, .42 PCT WO3, .01 PCT CO, .05 PCT PB, NIL ZN, TRACE PER TON AU, AND .11 OZ PER TON AG. BY FLOTATION OF A MINUS-48-MESH FRACTION, AN ASSAY OF 10.5 PCT WO3 WAS OBTAINED. SEE DALE, V.B., 1959, P. 64-65 FORFURTHER INFORMATION ON ASSAYS AND TECHNIQUES.

Comments

Comment (Deposit): THIS RECORD CONTAINS DATA FROM DUPLICATE RECORD D003607 OF J. WILLIAM HASLER WHICH HAS BEEN DELETED FROM MRDS. ; INFO.SRC : 1 PUB LIT

Comment (Workings): 110 FT. INCLINED SHAFT. 205 FT. OF DRIFTS, AND 88 FT. OF CROSSCUTS ON THE 100 FT. LEVEL. TWO SHORT ADITS. ONE HAULAGE ADIT. ONE 20 FT. SHAFT. ONE 65 BY 45 FT. OPENCUT FROM 12 TO 50 FT. DEEP, WITH A STOPE TO THE WEST. SEVERAL SHALLOW PITS.

Comment (Production): DURING THE YEARS 1939 TO 1943, CONCENTRATES CONTAINED 65 TO 75 PCT WO3.

Comment (Reserve-Resource): FURTHER EXPLORATION HAS GOOD CHANCE OF DISCOVERING MORE ORE.

Comment (Location): INFO FROM LAND.ST :(1964)

Comment (Commodity): SCHEELITE MINERALIZATION SEEMS TO OCCUR AT OR NEAR INTERSECTIONS OF NORTHWEST AND NORTHEAST TRENDING FRACTURES.

Comment (Development): MINE SHUT DOWN IN 1953. WORK BEGINNING 1952 FINANCED BY DMEA CONTRACT. ; ECON.COM: EASY ACCESS BY ROAD FROM ORACLE OR SAN MANUEL. MT. LEMMON ROAD. CAMPO BONITO ROAD.

Comment (Deposit): ORE BODIES ARE CONCENTRATED NEAR MOGUL FAULT IN SILICIFIED LIMESTONE AND ARE IRREGULARLY SHAPED MASSIVE AREAS WHICH HAVE NON-UNIFORM DISTRIBUTION OF SCHEELITE. SCHEELITE OCCURS DISSEMINATED, IN NARROW STRINGERS AND IN QUARTZ -SCHEELITE VEINLETS. APPRECIABLE AMOUNTS OF SCHEELITE EXIST ONLY IN THE HANGING WALL OF THE MOGUL FAULT; THERE IS A SMALL AMOUNT OF SCHEELITE IN THE FOOTWALL. PINK QUARTZITE BORDER ARE ON ALL SIDES EXCEPT NORTHEAST.
