OFR 85-86 - Juneau Gold Belt Area: Preliminary Mine, Prospect, Sample Location Maps and Descriptions. Alaska. 1986. The Juneau Gold Belt portion of the Juneau Mining District has historically had the greatest mining and exploration activity within the district and is the subject of this report. Between 1880 and 1983, the mines within the Juneau Gold Belt produced 6.7 million oz gold, 3.1 million oz silver, and 45 million lbs lead, all of which had a total value of about $157,000,000. Information in this report is based on an extensive literature search which included unpublished private company reports, U.S. Geological Survey, State of Alaska, and Bureau reports, personal interviews, and Bureau field work. The field work during 1985 revealed the locations of numerous adits, shafts and other old mine workings, many of which were...

As part of a cooperative project during 1986 and 1987, personnel from the U.S. Bureau of Mines and State of Alaska Division of Geological and Geophysical Surveys studied the mineral development potential of the Chilkat Peninsula and Islands, Alaska, as part of the larger Juneau Mining District study. About 4/5 of the area is within the Alaska State Chilkat and Chilkat Islands State Parks and not open to mineral entry. This study located four new (or previously unreported) gold- copper prospects. One of these, the Road Cut prospect, was examined by trenching, drilling and geophysics. While sufficient grades and tonnages were not delineated by this work to constitute an economic deposit, they are sufficient to encourage...

The data comprise selected portions of a data set that are published by C.J. Hodgson in "Preliminary Report on the Timmins-Kirkland Lake Area Gold Deposits File," which is available online as a digital image of a report. As an image, the data set cannot be analyzed. Consequently, selected portions of the data set are re-published here in a text file. The datum for the latitude and longitude is not specified in the report and is assumed to be the North American Datum of 1927 (NAD27). The Ontario Geological Survey, Ministry of Northern Development and Mines, Ontario, Canada kindly granted permission to re-publish these data. Hodgson,...

The Tofty mining district, near Manley Hot Springs in north-central Alaska, has been the scene of placer gold mining since 1906 and has produced more than 100,000 tr oz of gold and several hundred tons of byproduct tin, in the form of placer cassiterite. Although open -cut mining methods are currently employed, drift-mining methods were formerly utilized to mine the gold- and tin-bearing gravels. As part of the current Bureau of Mines Alaska -wide assessment of critical and strategic minerals, splits of concentrate samples collected in the 1950's from 11 tailings piles representative of the presently inactive Tofty drift mines were re-analyzed in 1983 for tantalum and columbium (niobium). Most of these concentrates... Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service; Tags: Columbium, Gold, Tin, Tofty, Alaska OFR 49-87 - Juneau Gold Belt Area 1986 Update. Alaska.
