      Free / History & Geology Undiscovered Placer Deposits in Alaska. November by Jim. Being an Alaskan geologist and prospector, I feel qualified to address the question of whether new placer gold discoveries are possible here in the 49th state. The results of these estimates are listed in table 1 and in appendix B. CONCLUSIONS Regional studies carried out from to in and near the Chugach National Forest evaluated the types of placer deposits present; the origins, characteristics, and distribution of placer gold; and the placer gold mineral development potential of all named.

      We are providing you an opportunity to purchase this digitally re-mastered book Placer Examination, Principles and Practice “While prepared specifically for use by the Bureau of Land Management personnel” to evaluate gold placer mining operations, with the hope that it would be “useful to the mining profession.”Thank you John Wells for being a bureaucrat with a concern for telling us. mining in Alaska, along with favorable gold prices, placer mining has seen a resurgence. Yet little has been understood about the economic impact of this form of mining. The last study of placer mining in Alaska, The Role of Placer Mining in the Alaska Economy, was conducted for the State of Alaska Department of Commerce.

MIRL Report No. 45 A SUMMARY OF GOLD FINENESS VALUES FROM ALASKA PLACER DEPOSITS Paul A. Metz Mineral Industry Research Laboratory and D. Hawkins Geology/Geophysics School of Mineral Industry University of Alaska Fairbanks, Alaska March, File Size: 1MB. Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits.

Alaska is known for its very rich Placer Deposits that are being discovered and mined even today. This book is a complete inventory of known placer deposits and prospects in the state along with their history and Author: Edward H. Cobb. Gold Placer Deposits Near Anchorage Alaska Edition contains an inventory of gold placer mines, prospects and deposits located within the Anchorage, Kenai, Seldovia, Seward and Tyonek quadrangles.

It contains (" x 11") pages of information on gold bearing streams including average yields per cubic yard, average yield of a 3 /5(2). Gold recovered from placers has alloyed with it other metals in varying pro­ portions.

The proportion of pure gold in these alloys is known as the fineness ot the gold and is expressed as parts in a thousand. Thus an alloy containing parts of gold is referred to as fine. Alaska placer gold ranges from moreCited by: Valdez Creek is a rich placer stream discovered in the Alaska Range during the early gold rush days.

It was discovered by prospectors working their way up the Susitna River in the manor described previously. They came to Valdez Creek, found good values, and followed the gold upstream to where they suddenly ran out of the yellow metal.

Rivers of Gold Placer Mining in Alaska Of all the gold ever mined in the world, approximately 1 to 2% (more than 33 million ounces) has come from Alaska. Seventy-two percent of this Alaskan gold was mined from placer deposits gold accu­ mulations in sands and gravels mostly deposited by streams and rivers.

Bygold was being mined near Windham Bay and near Sitka, in southeastern Alaska. The first major hard-rock gold mining began at the Alaska-Juneau, Perseverance, and Treadwell mines near present-day Juneau following the discovery of placer gold near tidewater in Residual placer gold deposits in this area include May’s Pit, located approximately 2 miles southeast of the Banner Creek Placer Gold Property, and Camp Pit, located approximately miles northwest of the property (both currently inactive).

Summary The Nome Gold Placer Mining Company owns acres of patented mining claims and 80 acres of Alaska state mining claims on Sherette Creek in the heart of the gold rich Kougarok Mining District of the Seward Peninsula about 50 miles north of Nome.

The Sherette Creek property has reasonably good surface access. USGS studies placer deposits as part of its Mineral Resources Program.

From the s Alaska Gold Rush (where 72% of the gold found came from placers) to modern-day rare earth deposits (of which quite a few are in placer deposits), USGS has.

Gold mining in Alaska was seriously affected in by the imposition of War Production Board Order L which closed nearly all of the gold mines during World War II (fig. After the war the placer mines of the Fairbanks district resumed large-scale operations, and this single district accounted for more than half the total annual gold.

PREVIOUS WORK The earliest works describing the placer gold deposits of the CNF were published by the USGS (). Moffit (6) and Johnson (7) were the first to publish detailed descriptions. the discovery of placer deposits in The total value of gold mined in the camp is about $15, The area was examined to determine (1) the extent and origin of the placer deposits and (2) of the placer gold and if possible the location of lode Size: 2MB.

Exploration for gold deposits as major targets began in Finland during the s. Exploration activities soon spread across most of the country, as indicated by the discovery dates of deposits given in Table Prior to the s, the common perception was that northern Europe lacked major gold by: 4.
