Comments on the geologic information

  • WARREN, ET. AL., (1965) REPORTS THAT MINE IS ASSOCIATED WITH BEEKMANTOWN DOLOMITE AND IMMEDIATELY ABOVE THE STONEHENGE LIMESTONE (= CHEPULTEPEC FORMATION). RADAR (1967) MAPS THE MINE INSIDE THE CHEPULTEPEC, WITH THE BEEKMANTOWN CONTACT RIGHT AT STATE ROAD 670 AND EXTENDING EASTWARD.

Comments on the workings information

  • AT THE END OF 1942 THE WORKINGS CONSISTED OF AN OPEN PIT ABOUT 37 M (120 FT) LONG, 27.4 M (90 FT) WIDE, AND ABOUT 15 M (50 FT) IN MAXIMUM DEPTH. THE MINE WAS SUBSEQUENTLY EXTENDED A SHORT DISTANCE TO THE EAST AND SOUTH AND WAS DEEPENED SLIGHTLY. IN 1981 THE PIT WAS NEARLY FILLED IN AND THE SURROUNDING AREA HAD BEEN GRADED AND RECENTLY SEEDED. THE PIT WAS ALSO DRY: IN THE PAST IT HAD BEEN REPORTED TO BE FILLED WITH WATER.

Comments on development

  • MINE WAS OPENED IN THE SUMMER OF 1941 AND WAS WORKED INTERMITTENTLY UNTIL THE END OF 1946. IT WAS FIRST OPERATED BY THE REPUBLIC MINING AND MANUFACTURING CO. AND THEN ALCOA MINING CO.

Subject category Comment text
Deposit STRIKE AND DIP ARE FROM NEARBY OUTCROPS, THERE IS NO BEDROCK EXPOSED IN OR ADJACENT TO THE MINE. THE BAUXITE IS LIGHT GRAY TO PALE BUFF. IT IS CHARACTERISTICALLY VERY FINELY PISOLITIC, THE PISOLITES BEING 1 TO 2 MM IN DIAMETER. SOME OF THE ORE, HOWEVER, CONSISTS OF COMPOUND PISOLITES, 2 TO 3 CM IN DIAMETER. SOME FINELY PISOLITIC BAUXITE SHOWS BEDDING IN WHICH LAYERS OF PISOLITES IN A FINE-GRAINED MATRIX ALTERNATE WITHLAYERS OF CLOSELY PACKED PISOLITES. THE APPEARANCE OF THE ROCK SUGGESTS A GRADATION UPWARD FROM LAYERS HAVING NO MATRIX TO THOSE HAVING A MATRIX. A BREAK IN DEPOSITION OCCURS BETWEEN EACH SUCCEEDING LAYER OF PISOLITES. THIS BAUXITE INDICATES SOME REDEPOSITION BY RUNNING WATER. DEPOSIT MAY HAVE BEEN AN OLD SINKHOLE.
Deposit TWO SMALL DEPOSITS HAVE BEEN REPORTED NEAR THE ALLEN MINE. ONE, ABOUT 183 M (600 FT) SOUTHWEST OF THE MINE, SHOWED ABUNDANT PISOLITIC FLOAT IN EARTH REMOVED FROM A CISTERN. AUGER HOLES IN THE VICINITY FAILED TO PENETRATE EITHER BAUXITE OR KAOLIN, AND THE FLOAT PROBABLY CAME FROM THE ALLEN DEPOSIT. THE OTHER SHOWING, ABOUT 610 M (2000 FT) WEST OF THE ALLEN MINE ON THE FORMER WAUGH FARM, IS A SMALL POCKET OF KAOLIN WHICH CROPS OUT ON A HILLSIDE. IT IS EXPOSED IN THE SIDE OF A GULLY ACROSS THE CREEK FROM, AND AT ABOUT THE SAME ALTITUDE AS, THE ALLEN MINE. THE POCKET IS ABOUT 6 M (20 FT) IN DIAMETER BUT NOT VERY THICK. ALTHOUGH A SMALL AMOUNT OF PISOLITIC FLOAT CAN BE SEEN IN THE IMMEDIATE VICINITY, THERE IS NO EVIDENCE OF A DEPOSIT LARGE ENOUGH TO BE MINED PROFITABLY. ; 2 UNPUB REPT; 3 FIELD OBSERV
