Con Mine The Con Mine (1938-2003) was the first gold mine developed in the Northwest Territories, Canada, just south of Yellowknife. The property was staked by Consolidated Mining and Smelting Company of Canada (Cominco) in September 1935 in response to the discovery of visible gold nearby; the name "Con" is an abbreviation of "Consolidated". The advent of winter prevented any prospecting from being conducted, but work in the summer of 1936 led to the discovery of numerous gold veins. The Con Mine entered production in 1938 and ceased operations in 2003. It has produced over 5000000 ozt of gold from 12,195,585 tons of ore processed. The mine was over 6000 ft deep.

Giant Mine The Giant Mine was a gold mine located on the Ingraham Trail, 5 km north of Yellowknife, Northwest Territories. Giant Mine is within the Kam Group, which is part of the Yellowknife greenstone belt. Gold was discovered on the property and mineral claims staked in 1935 by Johnny Baker, but the true extent of the gold deposits were not known until 1944 when a massive gold-bearing shear zone was uncovered beneath the drift-filled Baker Creek Valley.

Seawise Giant Seawise Giant, later Happy Giant, Jahre Viking, Knock Nevis, Oppama, and finally Mont, was a ULCC supertanker that was the longest ship ever built. It possessed the greatest deadweight tonnage ever recorded. Fully loaded, its displacement was 657019 t , the heaviest ship of any kind, and with a laden draft of 24.6 m , it was incapable of navigating the English Channel, the Suez Canal or the Panama Canal. Overall, it was generally considered the largest ship ever built. It was sunk during the Iran–Iraq War, but was later salvaged and restored to service. It was last used as a floating storage and offloading unit (FSO) moored off the coast of Qatar in the Persian Gulf at the Al Shaheen Oil Field.

Coal industry in Wales The coal industry in Wales has played an important role in the Industrial Revolution in Wales. Coal mining expanded in the eighteenth century to provide fuel for the blast furnaces of the iron and copper industries that were expanding in South Wales. The industry had reached large proportions by the end of that century, and then further expanded to supply steam-coal for the steam vessels that were beginning to trade around the world. The Cardiff Coal Exchange set the world price for steam-coal and Cardiff became a major coal-exporting port. The South Wales Coalfield was at its peak in 1913 and was one of the largest coalfields in the world. It remained the largest coalfield in Britain until 1925. The supply of coal dwindled, and pits closed in spite of a UK-wide strike against closures. The last deep mine in Wales, Tower Colliery, closed in 2008, after thirteen years as a co-operative owned by its miners.

Mine railway A mine railway (or mine railroad, U.S.), sometimes pit railway, is a railway constructed to carry materials and workers in and out of a mine. Materials transported typically include ore, coal and overburden (also called variously spoils, waste, slack, culm, and tilings; all meaning waste rock). It is little remembered, but the mix of heavy and bulky materials which had to be hauled into and out of mines gave rise to the first several generations of railways, at first made of wood rails, but eventually adding protective iron, steam locomotion by fixed engines and the earliest commercial steam locomotives, all in and around the works around mines.

International Smelting and Refining Company The International Smelting and Refining Company was a subsidiary of Anaconda Copper which operated primarily out of the International Smelter near Tooele, Utah. The International Smelter began operation in 1910 as a copper producer handling ores from Bingham Canyon and was expanded into a lead smelting operation in 1912. Copper smelting finished at International in 1946, and the lead smelter shut down in January 1972. The closure of the smelter would lead to the associated Tooele Valley Railway (which had their primary railyards at the smelter) to be shut down ten years later in 1982. The company also handled several other Anaconda owned interests. After the shut down of the International Smelter, environmental reclamation was performed by Anaconda Copper's successor company ARCO and the EPA Superfund program.

Megafan An alluvial megafan is a large cone or fan-shaped deposit built up by complex deposition patterns of stream flows originating from a single source point known as an apex. Megafans differ from Alluvial fans in their sheer size. Due to their larger size, they may be formed by different geomorphic processes. The criterion of what differentiates megafans from typical alluvial fans is an artificial one of scale. The scale divide varies in the literature, with the most common being a 100-km apex-to-toe length. Alternative values as little of 30-km apex-to-toe length have been proposed, as well as alternative metrics like coverage areas of greater than 10,000 square-km.

Jagersfontein Mine Jagersfontein Mine is an abandoned open-pit mine in South Africa located close to the town of Jagersfontein and about 110 km south-west of Bloemfontein. Since it was first established in 1870, two of the ten biggest diamonds ever discovered, the Excelsior and the Reitz (now called the Jubilee), were mined from Jagersfontein. The term "Jagers" has since been coined to denote the distinctive faint bluish tint of the gems from this mine. Among geologists, Jagersfontein is known as a kimberlite pipe, and a prime locality for mantle xenoliths, some of which are believed to have come from depths of 300 - .
