Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Placer Deposits of Alaska Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits. Any possibility that Alaska may again become an important source of metallic mineral commodities depends in part on an inventory of placer deposits and a knowledge of the geology of their source areas. Knowledge of Alaska's placer deposits is far from complete. Many mining camps have been, at best, the subject of only cursory examination by geologists or mining engineers who are at liberty to publish the results of their studies. Many placers are vaguely known from unconfirmed reports that someone was working on a creek, and in many instances, a creek bearing that name cannot now be identified with any particular stream. Such data are, of course, practically valueless and were generally ignored in pre paring this report. Many prospectors are reluctant to divulge data on their claims and this has undoubtedly caused some deposits to be lost or overlooked. Other major gaps in our knowledge result from the lack of bedrock exposures in many areas where valuable placer deposits were mined. In these areas, the determination of lode sources and their mode of occurrence during reconnaissance studies of mining districts was impossible.
