Geographic coordinates

Point of reference Geographic coordinates: Elevation UTM Precision Relative position Point location
Plant -99.49676, 34.78149 (WGS84) 477 100 GO SW OF MANGUM ON U.S. HWY 34 ABOUT 0.5 MI. AFTER CROSSING BRIDGE OVER SALT FORK, TURN S. ABOUT 5 MI. TURN ESE ABOUT 0.9 MI TO MILL SITE ON TOP OF HAYSTACK GYPSUM HILL, FOLLOWING WINDING UNIMPROVED ROAD. THE MEADOWS COPPER SHALE SHOULD CROP OUT ABOUT 600 FT S. OF THE MILL. THE ROAD INTO THE MILL PROBABLY CROSSES THE BED AT ABOUT 0.35 MI FROM THE ENTRANCE.

Comments on the location information

  • THE MEADOWS COPPER SHALE IS ABOUT 0.35-1.5 FT THICK, ABOUT 30-35 FT BELOW THE HAYSTACK GYPSUM, AND ABOUT 6 FT BELOW THE MARTY DOLOMITE, OR 0.5-1.5 FT BELOW THE KISER GYPSUM BED. THE MEADOWS IS A GREENISH-GRAY SHALE, NAMED AFTER THE PRINCIPAL LAND OWNER, MR. J.N. MEADOWS. THE DEPOSIT COVERS ABOUT 15 SQUARE MILES, S. OF MANGUM, IN SECS. 1, 2, 5, 6, 7, 8, 11, 12-3N-22W; AND SECS. 10, 15, 16, 20, 21, 22, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35-4N-22W.

Workings at the site

  • Type of workings Surface
    Name of workings LOBARIS COPPER CO.
    Area 3885HA
    Overall length 9655.8M
    Overall width 4827.9M

Comments on the workings information

  • THEY TRENCHED AND DRILLED CERTAIN AREAS.
  • Mineralization in the Meadows bed extends about 6 miles north-south and as much as 3 miles east-west, and it probably underlies about 12 square miles (Johnson, 1976, p. 12). The values in the workings fields appear to be computed from the 6 and 3 mi values. These are not the dimensions of the workings (are there any workings?), but the dimensions of the deposit.

Comments on development

  • MUCH OF THE ORE IS OXIDIZED (MALACHITE) AND THEY SOLD THEIR INTERESTS.

General comments

Subject category Comment text
Deposit THE DEPOSIT OCCURS OVER 23 SQUARE MILES OR MORE, BUT ONLY 12-15 SQUARE MILES MAY BE PRODUCTIVE.
Deposit BECAUSE OF A LARGE AMOUNT OF OXIDIZED ORE, THEY SOLD THEIR INTERESTS, AND THE AREA IS INACTIVE AND UNLEASED.
Deposit LOCKWOOD (1972; 1976) AND JOHNSON (1976) GIVE DETAILS. HANSEN (1958) DID THE GEOLOGY. STROUD AND OTHERS (1970, P. 38) COLLECTED 11 SAMPLES (C-4 TO C-14) FROM MEADOWS BED IN SW-27, NW-10-4N-22W; AND NE-2, SE-5, NW-8, NW-12, 3N-22W, WITH ANALYSES RANGING FROM 0.02 TO 1.00% CU.
Deposit Discovery Year: EARLY 1965
Deposit "the Mangum deposit is currently under development: it averages about 14 inches (36 cm) thick and about 1 percent copper" (Johnson, 1976, p. 3).
Deposit "The Mangum deposit is a copper shale nearly identical to that at Creta, but it generally is more oxidized and occurs in a slightly higher bed of the Flowerpot shale. Test pits have been dug and preliminary concentration tests made on the ore, and a mill is being built on the properties." (Johnson, 1976, p. 4).
