Report of geological reconnaissance in south-central Montana and northwestern Wyoming /

In the spring of 1953 a program of field reconnaissance for radioactivity in south-central Montana and northwestern Wyoming was authorized by the U.S. Atomic Energy Commission. Field procedures consisted of testing outcrops along roads, in cliffs, and around rim rocks, and testing mines, prospects and the dumps thereof with the appropriate instruments in an attempt to locate exposures of areas showing anomalous radioactivity and to ascertain the geological conditions under which such radioactivity occurred.

Exploration diamond drilling in the Boulder batholith, Jefferson and Silver Bow Counties, Montana /

Radiometric logging of the drill holes was accomplished by means of a Geiger counter-type probe. Samples for chemical assay were selected after checking the core with a Geiger counter and correlation with the radiometric logging record. The exploration project did not disclose significant amounts of ore-grade material although encouraging indications were found at two different properties.
