From Introduction and Summary: "This report gives results of an investigation of the carbonizing properties of 18 coals, including 2 from Alaska, 12 from British Columbia, 3 from Washington, and 1 from Utah. Each coal was carbonized in the standard 13-inch Bureau of Mines-American Gas Association (BM-AGA) retort at 900 degrees C."

Report of investigations issued by the U.S. Bureau of Mines on the estimated recoverable reserves of bituminous coal found in the Matanuska Valley Coal Field. The investigation includes studies of the area, and methods of mining which include diamond and churn drilling. This report includes maps, photographs, and illustrations.

Report of investigations issued by the U.S. Bureau of Mines on the Millet copper deposit near Lake Iliamna. The investigation included trenching, drilling, and mineralization zone sampling. This report contains tables, and maps.

From introduction: The purpose of this report is to present the results of the radiometric and mineralogic study of 19 samples from the Wiseman and Chandalar districts which are available in the Geological Survey's Alaskan collections. This work was done on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission.

From abstract: Reconnaissance in 1947 found uranothorianite and gummite associated with copper sulfides, iron oxides, molybdenite, gold, silver, bismuth, and thorite in placers of a headwater tributary of the Peace River in the eastern part of the Seward Peninsula, Alaska. Brief radiometric reconnaissance early in the summer of 1952 failed to locate the bedrock source of the radioactive minerals at the head of the Peace River, primarily because of the shielding-effect of widespread tundra cover. The samples obtained in 1952 indicate the presence of galena, sphalerite, pyrrhotite, covellite, and fluorite in addition to the minerals reported in the results of the 1947 reconnaissance.

From abstract: In the vicinity of Salmon Bay near the northeastern end of Prince of Wales Island, southeastern Alaska, samples obtained in 1951 from narrow, steeply dipping, carbonate-hematite veins contain as much as ,O.07 percent equivalent uranium. The average grade of these veins cannot be reliably stated because no systematic sampling has been done. No uranium or thorium minerals have been identified. Several chemical analyses indicate only a few thousandths percent uranium. Most of the radioactivity is apparently caused by thorium, which seems to be in or closely associated with red hematite.

Abstract: Zeunerite occurs near the surface of a granite stock on the southwest flank of Brooks Mountain, Alaska. The largest deposit is at the Foggy Day prospect where zeunerite is disseminated in hematite which partially or totally fills openings and vugs in a highly oxidized lensshaped body of pegmatitic granite and to a minor extent in openings and cracks in the weathered granite enclosing the lens. Although a few specimens from the pegmatitic lens contain as high as 2.1 percent equivalent uranium, the overall average content of the lens rock is between 0.1 and 0.2 percent equivalent uranium and about 0.07 percent equivalent uranium for both the lens material and the surrounding zeunerite-bearing granite.

Abstract: Reconnaissance for uranium in the Lost River area, Seward Peninsula, Alaska, during the 1951 field season revealed the presence of minor amounts of radioactive material in mineralized portions of rhyolitic dikes and in a small iron-enriched zone in limestone. The dikes contain as much as 0.01 percent equivalent uranium locally and average 00005 percent equivalent uranium. The radioactive material occurs as a secondary hematitic coating of the dike rock. The iron-enriched zone has an average content of about 0.06 percent equivalent uranium with the radioactive material occuring in limonite, hematite, goethite, and mimetite. The radioactivity of these minerals is due to the presence of uranium as an impurity. No uranium deposits of economic importance were found.

Report discussing the investigation of radioactivity at the Copper Creek related to copper mineralization in sedimentary rocks. The radioactivity probably originated from uranium relating to bornite and malachite.
