Report issued by the Bureau of Mines over studies conducted on the beneficiation of iron-copper ores. As stated in the summary, "this report summarizes the results of laboratory testing of copper-bearing magnetite ore from the Poorman, Rush and Brown, and Copper Center deposits, Kasaan Peninsula, Prince of Wales Island, southeastern Alaska" (p. 1). This report includes tables, maps, and illustrations.

A report regarding a reconnaissance for radioactive deposits in southeastern Alaska, 1952. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing an investigation of radioactivity occurrences, mostly caused by thorium in thorite and monazite, in various parts of southeastern Alaska. The geology and structural qualities of these radioactive areas are discussed.

This report provides an overview of Arctic-related issues for Congress and refers readers to more in-depth CRS reports on specific relevant topics.

From addendum: Two types of analyses for uranium in the stream-sediment samples are presented. One split of the stream-sediment samples was sent to Resource Associates of Alaska's laboratory, where they were analyzed for U by the fluormetric method after acid extraction. This is the method employed for U by most laboratories. The completeness of uranium extraction unavoidably varies with the particular type of uranium-bearing minerals present and possibly with the amount of iron, manganese, and carbonaceous material present, which can interfere with the extraction. Analyses by the method are shown in the text and appendix columns with the designation "RAA."
