Kerr Addison Mines Ltd.
Kerr Addison Mines Ltd was a Toronto-based mining and gas company that owned various mines throughout Canada, including the Agnew Lake Mine, the Kerr-Addison Mine and Chesterville gold mine. In the 1960s, Kerr Addison was Canada's largest gold producer. The injury of a snowmobiler on company property in 1975 led to a Supreme Court of Canada judgement setting precedent for future Occupier's Liability cases in Canada. History In 1904, H. L. Kerr was prospecting for uranium around Larder Lake and identified an area that he wanted to return to. Kerr spoke to Bill Addison, who visited the area in 1906. Shortly afterwards they formally registered their claim, formed Kerr Addison Gold Mines, and started the Kerr-Addison Mine. Production was slow in initial years, and ownership of the mine officially changed hands three times, with the third owner being Associated Goldfields Limited, buying the mine in 1917. Associated Goldfields Limited became Canadian Associated Goldfields in 1921 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Energy Companies Of Canada
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Natural Gas Companies Of Canada
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Gold Mining Companies Of Canada
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is i ...

Uranium Mining Companies Of Canada
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99.2739 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kerr-Addison Mine
The Kerr-Addison Mine (also known as the Kerr Mine) is an abandoned gold mine in the Kearns area of McGarry, Ontario. Gold ore was initially discovered around 1900, although production was low until 1936, then increasing through to 1960 and stopping in 1963. In the 1960s the mine was the largest gold producing gold mine in Canada. The increase in global gold prices caused the mine to reopen from 1990 until 1996, by which time over 12 million ounces had been produced. Ownership of the mine changed several times with surface and mining rights not always staying with the same corporation, until 2021, at which point Gold Candle Limited took ownership of both. Location and geology The mine is located on the north east edge of Larder Lake, in the Timiskaming District of Ontario, Ontario, Canada. The mine is on basalt volcanic rock.

Northwestern Ontario
Northwestern Ontario is a secondary region of Northern Ontario in the Canadian province of Ontario which lies north and west of Lake Superior and west of Hudson Bay and James Bay. It includes most of subarctic Ontario. Its western boundary is the Canadian province of Manitoba, which disputed Ontario's claim to the western part of the region. Ontario's right to Northwestern Ontario was determined by the Judicial Committee of the Privy Council in 1884ONTARIO-MANITOBA BOUNDARY CASE and confirmed by the Canada (Ontario Boundary) Act, 1889, of the Parliament of the United Kingdom. In 1912, the Parliament of Canada by the ''Ontario Boundaries Extension Act'' gave jurisdiction over the District of Patricia to Ontario, thereby extending the northern boundary of the province to Hudson Bay. For some purposes, Northwestern Ontario and Northeastern Ontario are treated as separate regions, while for other purposes they are grouped together as Northern Ontario.
