National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Gold-Lode Deposits, Fairbanks Mining District, Central Alaska.

PB222610

Publication Date	1973
Personal Author	Thomas, B. I.
Page Count	20
Abstract	The Fairbanks mining district forms an arc 40 miles long and 8 miles wide on the north side of the Tanana Valley, Central Alaska. This is a region of broad valleys and rounded hills ranging in elevation from 600 to 2,600 feet. Lode-gold production started in 1910 and has continued sporadically to the present, but the largest single mine produced only 40 tons per 24-hour day. Total recorded lode-gold production of the district is 241,000 fine troy ounces of gold from ore averaging 1.32 fine ounces per ton. The ore was mined chiefly from narrow veins and veinlets aligned along anticlinal folds at Ester Dome and the Pedro Dome-Cleary area. The only proven reserves are reported to be at the keystone Mines, Inc., Pedro Dome-Cleary area, and the Ryan Lode at Ester Dome. An inferred lode-gold resource for the district of approximately 4,000,000 ounces is considered to indicate only the order of magnitude of the lode-gold potential because of the absence of detailed data needed to evaluate the numerous deposits.
