The Burgess Claim is a uranium mine located in El Paso county, Colorado at an elevation of 7,031 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.

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.

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Analytical Data
Analytical Data: NINE 1-FT CHANNEL SAMPLES OF SANDSTONE AND CONGLOMERATE GAVE RANGE OF 60 TO 230 PPM EQUIV. U (50 TO 130 PPM U) WITH AVERAGE 133 PPM EQUIV. U (81 PPM U), 60 TO 150 PPM ZN, LT 10 TO 50 PPM PB, LT 10 TO 50 PPM CU, LT 10 PPM NI, LT 10 PPM CO, UP TO 1 PPM SB, LT 10 TO 60 PPM AS, 1 TO 6 PPM MO, 1000 TO 25000 PPM MN, 48000 TO 190000 PPM FE. TWO GRAB SAMPLES OF ARKOSE GAVE 130 AND 300 PPM EQUIV. U (50 AND 180 PPM U), 100 AND 300 PPM ZN, LT 10 PPM PB, 20 PPM CU, LT 10 PPM NI, LT 10 PPM CO, UP TO 1 PPM SB, 20 AND 80 PPM AS, 1 AND 6 PPM MO, 1500 AND 7500 PPM MN, 190000 AND 230000 PPM FE.

Comments
Comment (Commodity): ANALYSES SHOW TRACES OF CU, ZN, PB, NI, CO, SB, AS, AND MO BUT NOT IN SUFFICIENT QUANTITIES TO WARRANT THEIR INCLUSION AS OCCURRENCES. VALUES WERE STUDIED TO HELP DETERMINE ORIGIN AND GEOCHEMISTRY OF URANIUM
Comment (Location): ON LOW HILLTOP SOUTH OF UNNAMED TRIBUTARY OF KETTLE CREEK ; INFO FROM LAND.ST :(1974)
Comment (Deposit): SANDSTONE AND CONGLOMERATE BEDS OF DAWSON FM TREND APPROX N 43 W, DIPPING SLIGHTLY TO 5 DEG NE. MINERALIZED BODY IS IRREGULAR IN FORM WITH NW TREND AND SMALL LOCAL ROLLS PLUNGING 4 TO 12 DEG IN VARIABLE DIRECTIONS, MOSTLY SE. ANALYSES OF VERTICAL AND LOGITUDINAL SAMPLES SUGGEST DEPOSIT FORMATION BY (1) EARLY INTRODUCTION OF FE-MN OXIDES CONTAINING SMALL AMOUNTS OF CU, ZN, AS, AND MO DEPOSITED BY ALKALINE SOLUTIONS, (2) LATER DEPOSITION OF URANIUM AND POSSIBLY SILICA ALONG SMALL FRACTURES AT SAME TIME OTHER ELEMENTS WERE LEACHED. LOW URANIUM CONTENT WITH RESPECT TO EQUIV. URANIUM SUGGESTS URANIUM LEACHING AND RESIDUAL ENRICHMENT IN ITS DAUGHTER PRODUCTS BY GROUND-WATER ACTION
