George Avery Ranch Mine

The George Avery Ranch Mine is a uranium mine located in Pueblo county, Colorado at an elevation of 5,801 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: BACKGROUND RADIATION 0.02 MR/HR, RANGE 1.0 TO 5.0 MR/HR. FIVE CHIP SAMPLES ANALYZED BY AEC IN 1953 YIELDED 0.05, 0.23, 0.03, 0.07, AND 0.63 % U308. TWO GRAB SAMPLES ANALYZED BY AEC IN 1954 YIELDED 0.11 AND 0.20 % U308. TWO 0.4-FT CHANNEL SAMPLES ANALYZED BY AEC IN 1954 YIELDED 0.024 AND 0.103 % U308. TWO SAMPLES RADIOMETRICALLY ANALYZED BY AEC IN 1955 YIELDED 0.118 AND 0.283 % U308. KNOWLES (1960) REPORTS CHEMICAL ASSAYS OF 8 CHANNEL SAMPLES FROM DEPTH OF 87 FT IN INCLINE (IN % U308): 0.27, 0.59, 0.56, 1.05, 1.12, 0.37, 0.47, 0.24. ORE SHIPPED IN 1955 ASSAYED 0.13 % U308

Comments

Comment (Commodity): KNOWLES (1960) REPORTED A 1955 AEC ANALYSIS CONTAINING V205, BUT THIS IS UNVERIFIED

Comment (Location): ON EAST DIPPING CUESTA WEST OF TURKEY CREEK 4.7 MILES NE OF STONE CITY ; INFO FROM LAND.ST :(1978)

Comment (Reserve-Resource): ESTIMATE DERIVED FROM EXPLORATORY DRILLING PROGRAM IN 1956

Comment (Workings): SMALL SURFACE QUARRY; TWO 40-FT-DEEP VERTICAL SHAFTS, 60-FT ADIT, 212-FT INCLINE (INCLINED SHAFT)

Comment (Deposit): AEC PRELIMINARY RECON REPORT CITED CARNOTITE OCCURRING AS A COATING ON CARBONACEOUS SANDSTONE, AS FRACTURE FILLING, AND AS FILLING IN APPARENT SOLUTION CAVITIES. KNOWLES (1960) REPORTED THAT THE KATHRYN INCLINE ENCOUNTERED HIGH MINERALIZATION IN A 3- TO 5-FT-WIDE BRECCIATED ZONE ALONG A SMALL NORMAL FAULT OF LOW DISPLACEMENT. DEPOSIT COULD BE PARTLY DISSEMINATION, CHEMICAL PRECIPITATE ON FRACTURES AND IN CAVITIES, AND POSSIBLY REPLACEMENT IN FAULT BRECCIA ZONE.

Comment (Production): COMPOSITE PRODUCTION RECORD. NO PRODUCTION RECORDED FOR 1956, 1957, AND AFTER 1962. USBM FIGURES FOR 1958 GIVEN FOR GEORGE AVERY AND MINERAL RIGHTS MINES. CDM HAD NO RECORD FOR 1959, AND USBM WITHHELD FIGURES FOR 1959. ESTIMATE FOR 1959 LB U308 CALCULATED FROM ANNUAL TOTALS AND REPORTED CUMULATIVE TOTAL. AS CDM HAD NO ORE TONNAGE FIGURE FOR 1960, TOTAL ORE FOR 1959 AND 1960 (3515 ST) CALCULATED FROM ANNUAL TOTALS AND REPORTED CUMULATIVE TOTAL. INDIVIDUAL ORE FIGURES CALCULATED ON BASIS OF RELATIVE PERCENTAGES OF LB U308 PRODUCED IN 1959 AND 1960
