[EX Q]: Context_1 : The Ferris-Haggerty Mine Site was one of the richest components of the Grand Encampment Mining District in Carbon County, Wyoming. The site was first exploited by Ed Haggerty, a prospector from Whitehaven, England, in 1897 when he established the Rudefeha Mine on a rich deposit of copper ore. Haggerty was backed by George Ferris and other investors, of whom all but Ferris dropped out. The partners sold an interest to Willis George Emerson, who raised investment funding for improvements to the mine. These facilities included a 16 mi aerial tramway from Grand Encampment over the Continental Divide to the in Encampment. The mine's assets were eventually acquired by the North American Copper Company for $1 million. By 1904 the mine had produced $1.4 million in copper ore, and was sold to the Penn-Wyoming Copper Company. However, even with copper prices peaking in 1907, the company had difficulty making a profit from the remote mine site. The company was over-capitalized and under-insured and was suffered devastating fires at the mine site in March 1906 and May 1907 which halted production. Business disputes and a fall in copper prices prevented re-opening of the mine even after it was rebuilt. Machinery was salvaged after a foreclosure in 1913. A total of $2 million in copper ore was extracted from the mine during its life. Context_2 : Mullikkoräme zinc mine was active in Pyhäjärvi between the years 1989-2000. During this time 1.2 million tonnes of ore were mined. The ore contained in average 6.08% zinc, 0.30% copper and 17.05 sulphur also one tonne of ore contained 1.01 grams of gold. The ore from the mine was transported to the mine at Pyhäsalmi to be enriched. The ore was extracted during the years 1990-1993 and 1996-2000. Context_3 : The Silver Glen lies approximately 1 km to the east of the town of Alva, Clackmannanshire, Scotland, and takes its name from the silver that was mined there in the early 18th century. The story of the silver mine is a remarkable one. The deposit, the richest deposit of native silver ever found in the British Isles, was discovered just as the Jacobite rising of 1715 was breaking out, and its owner, Sir John Erskine, left to join the rebels, leaving his wife in charge of the mine. Some 40 tons of ore were raised and buried in barrels in the grounds of Alva House, whilst the richest of the ore was smelted and the ingots concealed under floorboards inside the house. The mine was then filled in during the aftermath of the failed rising, but its existence was revealed to the government by an employee of the Erskines. Samples of the ore were analysed by Sir Isaac Newton and found to be very rich. Sir John was later able to secure a pardon for his role in the rising, on condition he revealed all he knew about the mine, and gave a tenth of the proceeds to the government. Mining resumed a few years later and the remainder of the deposit was extracted. Later, in 1759, a vein carrying erythrite, an ore of cobalt, was found and gave a new lease of life to the mines, but it was soon exhausted. Context_4 : Kivimaa mine was gold and copper mine active during the years 1969-1970 in Tervola at Sivakkajoki. During this time 18 587 tonnes of ore were extracted which contained 2.0 grams of gold per tonne. The concentration of copper in the ore was 1,20%. Outokumpu Ltd., which owned the mine, mined the quartz-carbonate veins with highest concentration of gold and copper. The ore from the mine was transported to the mine of Vihanti to be enriched. The mining ended on the 12th of December 1969. The buildings at the mine were taken down in the summer of 1974. Context_5 : Iron mining in the United States produced 42.5 million metric tons of iron ore in 2015, worth US$3.8 billion. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah. Most of the iron ore was mined in northern Minnesota’s Mesabi Range. Net exports (exports minus imports) were 3.9 million tons. US iron ore made up 2.5 percent of the total mined worldwide in 2015. Employment as of 2014 was 5,750 in iron mines and iron ore treatment plants. Context_6 : The Thompson-Lundmark Mine was a gold producer in the periods 1941–1943 and 1947–1949, near Yellowknife, Northwest Territories. Gold was discovered here in 1938 by Fred W. Thompson and Roy Lundmark; they staked 46 claims that were incorporated into the mine. Underground and shaft work began in 1939. The mine processed 133,989 tons of ore to produce 70,339 troy ounces (2188 kg) of gold and 13,782 troy ounces (429 kg) of silver. The abandoned site was destroyed by forest fires during 1998. A detailed history is available in the link below. Context_7 : The Key Lake mine is a former uranium mine in Saskatchewan, Canada, and the site of the largest uranium mill in the world. It is five-hundred and seventy kilometres north of Saskatoon by air on the southern rim of the uranium-rich Athabasca Basin. Key Lake was initially developed to open-pit mine two nearby uranium ore deposits: the Gaertner deposit and the Deilmann deposit. Mining of this ore ceased in the late 1990s; the Key Lake mill now processes uranium ore from the McArthur River mine and from existing stockpiles on site. High-grade ore from McArthur river is blended with lower grade local rock before being passed through the mill. The mill has an annual production capacity of 18 million pounds of UO. In addition, ammonium sulfate fertilizer is produced as a byproduct from used reagents. The pits of the mined out local deposits are being used as mill tailings management facilities. Context_8 : Leckie Mine, also known as Penrose Mine and Little Dan Mine, is an abandoned gold producing underground mine in Northeastern Ontario, Canada, located on the eastern shore of Arsenic Lake 4 km north of the town of Temagami. It is entirely owned by Temagami Gold Inc. An estimated 483,500 tonnes of ore remain in the mine, which could contain 102,720 ounces of gold. Context_9 : The Kiruna mine is the largest and most modern underground iron ore mine in the world. The mine is located in Kiruna in Norrbotten County, Lapland. The mine which is owned by Luossavaara-Kiirunavaara AB, a large Swedish mining company, has an annual production capacity of over 26 million tonnes of iron ore. In 2008 the mine produced 27.5 million tonnes of iron ore. The Kiruna mine has an ore body which is 4 km long, 80 m to 120 m thick and reaching a depth of up to 2 km . Since mining began at the site in 1898, the mine has produced over 950 million tonnes of ore. Context_10 : Bukit Besi is a small mining town in Dungun constituency, Terengganu, Malaysia famous for its high quality iron ore. The ferum content of Bukit Besi's iron ore is more than 70% hence making it a very high grade sought after iron ore and is Malaysia's best known grade of iron ore. The iron ore reserve was discovered by the British during the colonial era. More than 90% of Bukit Besi's iron ore reserves have already been mined by colonial powers Britain and Japan in the 1900s. It is estimated that roughly 50 million metric tonnes of iron ore deposits remain as of today. Recent events have seen the Terengganu state government awarding iron ore mining concessions to China-based companies such as Eastern Steel and Shougang Steel whom together with their local Malaysian partners will mine the remaining iron ore reserves in Bukit Besi over the span of 25 years hence providing a new lease of economic opportunities for locals in the area. fact_1 : The Thompson-Lundmark Mine was a gold producer in the periods 1941–1943 and 1947–1949, near Yellowknife, Northwest Territories. fact_2 : Leckie Mine, also known as Penrose Mine and Little Dan Mine, is an abandoned gold producing underground mine in Northeastern Ontario, Canada, located on the eastern shore of Arsenic Lake 4 km north of the town of Temagami. Answer: gold
