Geologic information

Identification information

Deposit ID 10022133
MRDS ID DE01963
Record type Site
Current site name Abilene Lake-1

Geographic coordinates

Geographic coordinates: -99.88816, 32.23627 (WGS84)
Elevation 597
Location accuracy 100(meters)
Relative position THE CRETACEOUS (ANTLERS SANDSTONE) OCCURS AT EL. 2160-2180 FT OVER MOST OF THE AREA AND DOWN THE SIDES OF THE ELM CREEK VALLEY. PROBABLY SOMEPLACE WITHIN 2 MI OF THE DAM, ALONG ELM CREEK OR ONE OF ITS TRIBUTARIES, THE COPPER MINERALS OCCUR. THE ABILENE NEWSPAPER SAID THAT ONE OUTCROP WAS 100 FT LONG AND 7 FT THICK, AND IT ASSAYED AT 43% CU. CHARLES S. BROWN, OF POST, AND LEE A. HARRISON, OF JAYTON, LEASED THE LAND. GO ABOUT 18 MI SW OF ABILENE ON TEXAS HWY. 89, THROUGH BUFFALO GAP, AND ABOUT 5 MI BEYOND TO LAKE ABILENE DAM. THE MIDDLE CLEAR FORK FORMATION OCCURS IN THE VALLEY OF ELM CREEK, BETWEEN 1960 FT AT BASE OF DAM AND 2060 FT AT BASE OF ANTLERS SANDSTONE. SOMEPLACE THERE MUST BE LENSES OF COPPER MINERALIZATION IN THIS AREA ON THE BILBY RANCH.

Deposit OUTCROP
Deposit HALE (1977, P. 228) IS REFERENCE. HE QUOTED AN ARTICLE IN THE ABILENE DAILY REPORTER (MARCH 19, 1918, P. 1) THAT COPPER MINERALS WERE FOUND ON THE BILBY RANCH. A YEAR LATER, IN 1919, THE LAKE ABILENE RESERVOIR WAS BUILT NEARBY AND THE COPPER EXPLORATION CEASED. THERE WAS NO EXACT LOCALITY LISTED.
