Abstract
The uranium deposits, three-fourths of a mile south of Garo,
Park County, Colo., were mined over 30 years ago for radium ore. The old
workings are now abandoned and inaccessible. Forty tons of ore that
contained 1.0 percent uranium are reported to have been mined from two
light-gray sandstone beds that are stratigraphically about 100 feet
apart. The minerals reported to occur in these sandstones are carnotite,
malachite, azurite, calciovolborthite, and volborthite. The deposits are
in close proximity to a radioactive cherty limestone which is one foot
thick, that contains as much as 0.01 percent uranium. The uranium in
the carnotite and the uranium in the chert may be genetically related.
Mr. ¥. H. Gaddis of Hartsel, Colo., has recently attempted to reopen
some of the workings, but as of April 1951 this operation had not
revealed any significant new data.
Future prospecting should be initiated in the two sandstone beds
that have been mineralized. The chert can be used as a marker bed in
correlating the sandstones from one exposure to another.
