A shield is a protective device, meant to intercept attacks. The term often refers to a device that is held in the hand, as opposed to armour or a bullet proof vest. The oldest form of shield was a protection used to block attacks by hand weapons and missiles. Shields have varied greatly in construction over time and place. Sometimes shields were made of metal, but wood or animal hide construction was very much more common; wicker and even turtle shells have been used. Many surviving examples of metal shields are generally felt to be ceremonial rather than practical, for example the Yetholm-type shields of the ...

The Argyle diamond mine is a diamond mine located in Australia. The Argyle mine is the largest diamond producer in the world by volume, although due to the low proportion of gem-quality diamonds, is not the leader by value. It is the only known significant source of pink diamonds, producing 90 to 95 % of the world's supply. The Argyle diamond mine is also notable for being the first commercial diamond mine exploiting a volcanic pipe of lamproite, rather than the more usual kimberlite pipe. The mine is owned by the Rio Tinto Group, a d ...

In 1883, a CPR crew accidentally discovered natural gas near Medicine Hat, Alberta. In 1912, the CPR set up its Department of Natural Resources in Calgary to manage its timber, oil, gas, and mineral rights as well as land sales and immigration and colonization activities. In 1958, CP created Canadian Pacific Oil and Gas Company (CPOG) to manage its oil, gas, and mineral rights. CPOG was merged with Central-Del Rio Oils to form PanCanadian Energy in 1971, to expand CP portfolio into energy exploration. PanCanadian was spun off by CP in 2002 an ...

Canadian Shield rock forms the nucleus of the North American continent. Other geological structures assumed positions around or on top of the Shield millions of years after it was formed. The Rocky Mountains are relative newcomers on the geological stage, having risen a mere 60 million years ago. Most Shield rocks were formed well over a billion years earlier, during the very first chapter of the pla ...

Coal mining is the extraction of coal from the Earth for use as fuel. Coal mining - Methods of extraction. The most economical of methods of coal extraction from coal seams depends on the depth and quality of the seams, and also the geology and environmental factors of the area being mined. If the coal seams are near the surface, the coal is extracted by strip mining. Strip mining exposes the coal by the advancement of an open pit or strip. As the coal is exposed and extracted, the overburden from th ...

Borehole Mining (BHM) is a remote operated method of extracting (mining) of mineral resources through boreholes by means of high pressure water jets. This process can be carried-out from land surface, open pit floor, underground mine or floating platform or vessel through pre-drilled boreholes. Borehole mining - The process. A borehole is drilled from land surface to a desired depth, where then an actual borehole mining will take a place. A casing column is lowered down the hole. Since BHM ta ...

Yetholm-type shields are artefacts dating from 1200-800 BC during the bronze age. Some twenty shields of this type have been discovered, all from the British Isles except for one find in Denmark. The shields vary significantly in size, but the shields are otherwise very similar in the details of their design. Shields of this type are named for Yetholm in southern Scotland where a peat bog yielded three examples. Typically, the shields are made of copper alloy sheet metal about 0.6mm thick. The copper alloy is a high-tin bronze: ...

The Battersea Shield is a sheet bronze shield dating to circa 300 BC. It was dredged from the River Thames in the UK, and probably was deposited as a ritual gift to the spirits of the River, as were many other pieces of bronze, iron work and human skulls that have found themselves into the Thames and other rivers. The Shield is decorated with repoussé decoration and enamel. The decoration is typically Celtic in terms of art style consisting of circles and spirals. It has been suggested it was a decorative piece and would not have been an effective shield in combat. The shield was disc ...

Aside from Quebec "sovereignists" or separatists whose goal is a separate Quebec with an "economic union" with Canada, most economic and political nationalists from all parts of the nation are interested in Canada having a self sufficient economy and having completely independent political decision making, free from any American pressures. Today Canada is a partner in the North American Free Trade Agreement (NAFTA) which has eliminated tariffs on many Canadian goods. Many nationalists complain leaves room for American corporations to challenge ...
