The Ashland Coal Field, Rosebud, Powder River, and Custer Counties, Montana (open access)

The Ashland Coal Field, Rosebud, Powder River, and Custer Counties, Montana

From introduction: The detailed information concerning the coal deposits of the Ashland field set forth in this report has been obtained in the course of an investigation that has been conducted both as a part of the United States Geological Survey's general systematic study of western coal lands and as an aid in the administration of the public lands. With the information obtained on the location of outcrops, the number, distribution, and thickness of coal beds, the accessibility of the coal, and the thickness of the overburden, the public lands of the region are classified as to their coal value; coal-bearing lands are differentiated from noncoal-bearing lands; and the administration of the coal-land leasing law is facilitated.

Preliminary Report on the Rimini Area, Jefferson City Quadrangle, Jefferson County and Lewis and Clark County, Montana (open access)

Preliminary Report on the Rimini Area, Jefferson City Quadrangle, Jefferson County and Lewis and Clark County, Montana

Abstract: A number of radioactivity anomalies and secondary uranium minerals have been found in the Rimini area near the northwestern margin of the Boulder batholith. Most of the anomalies are associated with chalcedonic vein zones that consist of one or more veins of cryptocrystalline and fine-grained quartz in silicified quartz monzonite and alaskite. Seventeen of the anomalies were found along veins that contain base and precious metals; nine were along veins in the vicinity of the village of Rimini from which there has been production of lead, silver, zinc, and gold.

The Comet and Gray Eagle Mines and Adjacent Area, Jefferson County, Montana (open access)

The Comet and Gray Eagle Mines and Adjacent Area, Jefferson County, Montana

Abstract: Anomalous radioactivity and uranium minerals have been found on the dumps of the Comet, Gray Eagle, and Silver Hill mines situated along the Comet-Gray Eagle shear zone. The shear zone is from 50 to 200 feet in width and has been traced 5 1/2 miles. The Gray Eagle mine is currently being reopened but no underground work, with the exception of a few shallow shafts and adits, has been done between the Gray Eagle and Comet mines. Because of the high U3 08 content of the samples from the Comet and Gray Eagle dumps, it is recommended that a minimum of four diamond drill holes totaling 3, 000 feet be drilled by AEC between the two mines to intersect the shear zone 300 to 500 feet below the surface. This drilling should be made contingent upon the results of the Gray Eagle exploration.

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California

From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

The Kevin-Sunburst Oil Field and Other Possibilities of Oil and Gas in the Sweetgrass Arch, Montana (open access)

The Kevin-Sunburst Oil Field and Other Possibilities of Oil and Gas in the Sweetgrass Arch, Montana

From introduction: The discovery of oil near Kevin, Mont., in March, 1922, gave prominence to the Sweetgrass arch, which is a large structural uplift somewhat similar in size and degree of folding to the Cincinnati arch. Most of the development so far attempted on this fold has been on the Kevin-Sunburst dome, a bulge upon the crest of the arch just south of the Canadian boundary. The dome covers about 16 townships, is nearly circular in outline, and has very low dips away from its highest point in all directions. Within the last five years (1923-1927) about 1,500 wells have been drilled upon it, over 880 of which are rated as productive. Since May, 1925, the field has stood second in production in the Rocky Mountain States being exceeded only by Salt Creek.
