Vital Creek
Vital Creek is a creek located in the Omineca Country region of British Columbia, flowing eastward from its source in the Vital Range to meet Silver Creek, joining that creek from the west about 5 miles from its mouth into the Omineca River, about 41 km northeast of Takla Landing. History The gold deposits of Vital Creek were discovered in 1869 by Vital Laforce, who had also been among the four discoverers of gold along Williams Creek (British Columbia), Williams Creek, which was the foundation of Barkerville. This was the first creek mined in the Omineca Gold Rush, Omineca. Late in the mining season of 1870, $7,000 was taken out by a party of 15 Chinese miners, giving some hope that significant gold might yet be found in the region. The creek has been mined for gold and silver, which occurred simultaneously and were unusual to find in that way. It has been hydraulicked and mined by Chinese syndicates like Gow Sing and Co. The bulk of the gold was obtained on bedrock and in cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omineca Country
The Omineca Country, also called the Omineca District or the Omineca, is a historical geographic region of the Northern Interior of British Columbia, roughly defined by the basin of the Omineca River but including areas to the south which allowed access to the region during the Omineca Gold Rush of the 1860s. The term Omineca District also refers to the Omineca Mining District which referred to the same area but was a government administrative division. Today the name loosely refers to the region northwest of Prince George and north of Hwy 16 (the Yellowhead Highway) and occurs in the names of such entities as electoral districts, e.g. Prince George-Omineca.

Drift (mining)
Drift mining is either the mining of an ore deposit by underground methods, or the working of coal seams accessed by adits driven into the surface outcrop of the coal bed. A drift mine is an underground mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into the ore seam. Random House dictionary says the origin of the term "drift mine" is an Americanism, circa 1885–1890. Drift is a more general mining term, meaning a near-horizontal passageway in a mine, following the bed (of coal, for instance) or vein of ore. A drift may or may not intersect the ground surface. A drift follows the vein, as distinguished from a crosscut that intersects it, or a level or gallery, which may do either. All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exp ...

Arquerite
Arquerite is a naturally occurring alloy of silver with mercury. It is a very rare mineral, consisting of a silver-rich variety of amalgam, containing about 87% silver and 13% mercury. Arquerite has been reported from only four localities worldwide, two in Chile and two in British Columbia, Canada. Other names for arquerite include argental mercury, mercurian silver, and silver amalgam.

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phyllite
Phyllite ( ) is a type of foliated metamorphic rock created from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation.Stephen Marshak ''Essentials of Geology'', 3rd ed. It is primarily composed of quartz, sericite mica, and chlorite. Phyllite has fine-grained mica flakes, whereas slate has extremely fine mica flakes, and schist has large mica flakes, all mica flakes of which have achieved a preferred orientation. Among foliated metamorphic rocks, it represents a gradation in the degree of metamorphism between slate and schist. The minute crystals of graphite, sericite, or chlorite, or the translucent fine-grained white mica, impart a silky, sometimes golden sheen to the surfaces of cleavage, called "phyllitic luster". The word comes from the Greek ''phyllon'', meaning "leaf". The protolith (or parent rock) for phyllite is shale or pelite, or slate, which in turn came from a shale protolith. Its constituent platy minerals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cache Creek Complex
The Cache Creek Terrane (alternately known as Cache Creek Melange ) is a geologic terrane in British Columbia and southern Yukon, Canada.

Nephrite
Nephrite is a variety of the calcium, magnesium, and iron-rich amphibole minerals tremolite or actinolite (Aggregate (geology), aggregates of which also make up one form of asbestos). The chemical formula for nephrite is calcium, Ca2(magnesium, Mg, iron, Fe)5silicon, Si8oxygen, O22(Ohydrogen, H)2. It is one of two different mineral species called jade. The other mineral species known as jade is jadeite, which is a variety of pyroxene. While nephrite jade possesses mainly grays and greens (and occasionally yellows, browns or whites), jadeite jade, which is rarer, can also contain blacks, reds, pinks and violets. Nephrite jade is an ornamental stone used in Stone carving, carvings, beads, or cabochon cut gemstones. Nephrite is also the official state mineral of Wyoming. Nephrite can be found in a translucent white to very light yellow form which is known in China as ''mutton fat'' jade, in an opaque white to very light brown or gray which is known as ''chicken bone'' jade, as wel ...

Omineca Gold Rush
The Omineca Gold Rush was a gold rush in British Columbia, Canada in the Omineca region of the Northern Interior of the province. Gold was first discovered there in 1861, but the rush didn't begin until late in 1869 with the discovery at Vital Creek. There were several routes to the goldfields: two were from Fort St. James, one of which was a water route through the Stuart and Tachie Rivers to Trembleur Lake to Takla Lake and the other was overland, called the Baldy Mountain route. A third route came in overland from Hazelton on the Skeena River and a fourth route used the Fraser River and crossed over the Giscome Portage to Summit Lake, through McLeod Lake, and up the Finlay River to the Omineca River. 1860s Toy's Bar The first recorded gold discovery in the Omineca district was made by William Cust and Edward Carey in the summer of 1861. The two men had traveled up from Alexandria that spring and returned in the fall with 60 ounces of gold between them. Despite such a small ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barkerville
Barkerville was the main town of the Cariboo Gold Rush in British Columbia, Canada, and is preserved as a historic town. It is located on the north slope of the Cariboo Plateau near the Cariboo Mountains east of Quesnel. BC Highway 26, which follows the route of the Cariboo Wagon Road, the original access to Barkerville, goes through it. History Founding Barkerville is located on the western edge of the Cariboo Mountains in British Columbia. It was named after Billy Barker from Cambridgeshire, England, who was among those who first struck gold at the location in 1861. His claim was the richest and the most famous. Barkerville was built up almost overnight, and was a case of "growth via word of mouth". It grew as fast as the word of Barker's strike spread. His claim would eventually yield 37,500 ounces (1,065 kg/2,350 lb) of gold. Before the construction of the Cariboo Wagon Road, people hauled their own supplies to Barkerville, either on their backs or in a ...
