Near the head of Lost Chicken Creek, the valley is separated from that of Chicken Creek by a gravel-capped terrace about feet above Chicken Creek which, according to USGS reports, is richly auriferous. Placer mining on Lost Chicken Creek occurred along the creek and more extensively on a bench at the head of the creek, following the the discovery in The deposit has been mined from about to the present, making it one of the longest continually mined deposits in Alaska.

The original discovery and early mining occurred on the bench between Chicken Creek and Lost Chicken Creek. The bench deposit was initially mined by drifts run from shafts 33 to 53 feet deep. The creek and bench gravels have also been mined by hydraulic, bulldozer, and sluice box methods. Lost Chicken Creek was one of the major gold producers of the Fortymile mining district in the early 's.

Placer gold occurs in the lower part of the gravel and on top of bedrock; the gold is mainly small, flattened pieces. Good-size nuggets are rare, but one weighing nearly 1. The fineness of gold mined from to ranged from A mean of seven assays indicates an average fineness of parts of gold per thousand and parts of silver per thousand; this is higher fineness than gold from the nearby Chicken Creek and Myers Fork placers.

The rocks in the vicinity of Lost Chicken Creek are granitic Migration from horizon to symphony of the Taylor Mountain batholith of Triassic age and upper Paleozoic greenschist-facies metasedimentary and metavolcanic rocks Werdon and others, These units have been cut by high-angle faults.

The bedrock at the head of the creek exposed by placer mining is quartz diorite cut by a Tertiary basalt dike Mertie, [B C]. Quaternary alluvium and colluvium deposits are extensive in the valley of Lost Chicken Creek; they largely consist of gravel and lesser silt and sand overlain by muck.

Placer gold mining of these deposits has exposed numerous Pleistocene mammalian fossils including rare birds, mammoth, horse, bison, musk oxen, Saiga antelope, Yukon ass, moose, elk, wolverine, saber-toothed tiger, caribou, collared lemming, an extinct American lion and bison.

Placer concentrates mainly contain magnetite, ilmenite, garnet, jasper, amethyst, wood agate and zircon.

Gold in bedrock only rarely has been found directly associated with placer deposits in the Fortymile River area and other placer districts of the Yukon Tanana upland. When the mine was visited in early September good cuts in greenish gray highly sheared diorite or quartz diorite were exposed about 2, m above the mouth of the Creek The rock contained abundant sulfides and much of it was stained yellow and orange brown.

Six grab samples of bedrock were collected from one cut and analyzed for gold by RM O Leary using the atomic absorption method. Two of the six samples contained 0. Gold was not detected in the other four samples limit of detection 0. The samples which contained gold were stained orange brown and one had many visible sulfides.

These bedrock analyses suggest that some Lost Chicken placer gold is probably locally derived from sheared mineralized diorite. Fossils come from sediments interbedded with the Lost Chicken volcanic ashbed dated at 2. Climate was wetter and less continental, and there was probably little or no permafrost.

At least one other Pliocene volcanic ashbed the Fortymile tephra occurs at the site and is also associated with plant and insect fossils. Among these fossils are extinct plants and insects like those found at other Tertiary sites in northern Canada and Alaska. The Lost Chicken sequence is the same age as the Beaufort Formation on Meighen Island, more than km to the north.

Like Lost Chicken, Meighen Island sediments contain fossils representing a diverse boreal environment. Inwe had the opportunity to lease the western edge of the Lost Chicken claim block. We spent part of that season stripping and mining one 'cut' which was over 50 ft deep against the hillside, but it was worth it as can be seen in the pans and jar of oz below.

Finally, in February, the deal was closed. Starting in the mining season ofBS Gold Ventures will be mining the remaining deposit on Lost Chicken Hill and Chicken Gold Camp intends to provide limited access for recreational activities.A campaign to create some change or achieve a goal is another kind of movement, like the civil rights movement of the s and 60s.A major section of a musical piece is also called a regardbouddhiste.com movement of a symphony can have a different tempo and .
