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.

During the summer of 1953, the Commission sponsored its first diamond drilling program in the batholith to explore at depth a number of interesting uranium showings. Operations commenced in July 1953 and ended in November 1953, with the completion of 60 holes totaling 9,807.5 feet.

Part I -- The Boulder batholith region is located in southwestern Montana (Figure 1). Uranium was first discovered in the area in June 1949 and since then many new occurrences have been recognized, although a few are of commercial importance.
