The Eskay Creek gold-silver deposit is hosted by felsic volcanic rocks near the top of the Lower to Middle Jurassic Hazelton Group, and lies within the Stikine Arch of north-western British Columbia, Canada. Published reserve figures are as follows: Reserves, - Mt @ Lead g/t Au, g/t Ag, % Zn, % Cu (AME, ) Reserves, - Mt @ 26 g/t Au, g/t Ag (Dawson, etal.
These mineral occurrences are related to Middle Eocene plutons of the Coast Plutonic Complex. and silver deposits at Bowser Creek book All are late- to post-intrusive deposits emplaced about million years ago.

Irregular behavior in the zinc-grade model may be due to these factors. Polymetallic veins of two types appear to exist --a base-metal polymetallic vein worked primarily for a base metal or metals and silver and a gold-silver polymetallic vein with copper, lead, and zinc production likely in.

Some of the silver mines in Mexico have been operating for over years, and are so rich in silver ore that it is estimated that up to one third of all the silver ever mined in history came from this region. Compare this to average mine lives worldwide usually measured in years or decades, not centuries.
Silver is normally mined as a by-product in lead/zinc mines, but in Mexico the ore often. Ainsworth is a popular tourist destination. First Nations people fished and lived in this area for centuries prior to the townsite being created by George Ainsworth in His interest was in the development of the silver, lead and zinc deposits in the area.
The association of Hawaiian-Emperor volcanism with a large-scale central Pacific anisotropy anomaly at ~ km depth can be explained by tapping of shallow melt sources in a perisphere/LLAMA (layer of lateral advection of mass and anisotropy) model. SUMMARY The Anyox copper mining camp played a key role in the early development of northwestern British Columbia.
It was discovered in and through persistence and belief in the project (a common theme in modern exploration), it was explored and brought into production in by Granby Consolidated Mining, Smelting and Power Co., Ltd.

Nevada is the nation’s leading producer of silver, barite, mercury, and lithium. Much of the silver is a co-product or by-product of gold production, and all the mercury currently produced is a by-product of precious metal recovery.
Lithium is extracted from brine that occurs in Tertiary valley-filling sediments. EPA Superfund Record of Decision: Continental Steel Corp. Kokomo, IN 9/30/ PB EPA R November The Silver Demon deposit is similar in many ways to the Nevada quicksilver deposits and present-day hot-spring deposits.
The Silver Demon ore occurrence may represent a gradation from the common epithermal disseminated silver-gold deposit to the cinnabar deposit. It was another multi-tiered mine.
