Colomac Airport (TC LID: CFY8) , was located near Colomac Mine in the Northwest Territories, Canada where caribou may be found on the runway.
 Prior permission was required to land except in the case of an emergency.
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.
The San Manuel Copper Mine was a surface and underground porphyry copper mine located in San Manuel, Pinal County, Arizona.
 Frank Schultz was the original discoverer, in 1879, but the main body of the deposits were discovered by Henry W. Nichols in 1942.
 The exploration drilling went on from 1943 to 1948, with the first mine shaft built 1948.
 Louis Lesser developed a mining city to service Nichols’ newly discovered deposits, and the development was completed about 1954.
 The first major production began in 1955, and the mine and smelter were permanently closed in 2003.
The Wright-Hargreaves Mine is a gold mine located in Kirkland Lake, Ontario.
 In late July 1911, Bill Wright and his brother-in-law Ed Hargreaves discovered the first visible gold in what would later become the Kirkland Lake camp.
 In 1913 the No. 1 shaft was sunk to a depth of 85 feet.
 By the end of its production, the Wright-Hargreaves would be the deepest mine in the Kirkland Lake camp with workings at the 8200 foot level.
 The mine was in regular production between 1921 and 1965, with a total production of 4,821,296 ounces of gold at an average grade of 0.49 ounces per ton.
The Ptarmigan and Tom Mine were gold producers located in the Northwest Territories, Canada at Yellowknife.
 The property was staked by prospectors in 1936 and acquired by Cominco in 1938.
 The mine first produced between 1941 and 1942 but closed due to wartime restrictions.
 The old property was demolished in 1969–1970.
 A new company, Treminco Resources Limited, reopened the workings in 1985 and production from the Tom ( ) portal began in 1986 with material being trucked to Giant Mine.
 The old Ptarmigan ( ) mine shaft was dewatered and production began in 1987.
 A new mill was built at the property and was operational in July 1989.
 Low gold prices forced the company to close the mines in 1997.
 Total gold production has been approximately 120,000 troy ounces (3700 kg).
The Løkken Mine is and underground pyrite mine located in the municipality of Meldal in Sør-Trøndelag, Norway.
 The mine was operative from 1654 to 1987, from the mining community Løkken Verk.
 It contained the largest deposits of its kind in Norway.
 Between 1654 and 1845, a total of 11,300 tons of copper was produced from the mine.
 From 1904 the mine was run by the company Orkla Grube-Aktiebolag, and until 1987 a total of 24 million tons of pyrite was produced from the mine.
 In addition to sulphur, the pyrite contained about 2% copper, in addition to zinc and traces of silver and gold.
 The products were originally transported to the sea by horse and sledge during winter time.
 From 1908 the ore was transported by the Thamshavn Line, which was the first electrical railway line in Norway.
 The annual production was about 350,000 tons of ore during its final years.
Negus Mine was a gold producer at Yellowknife, Northwest Territories, Canada, from 1939 to 1952.
 It produced 255,807 troy ounces (7956 kg) of gold from 490,808 tons of ore milled.
 The underground workings were acquired by adjacent Con Mine in 1953 and were used for ventilation purposes until Con Mine closed in 2003.
Las Bambas copper mine is a large project located in Apurímac, Peru.
 It is an open-pit mine located at altitude of about 4000 meters above sea level.
 It is a polymetallic mine which significant mineral resources and ore reserves of copper with an estimated mine life of at least 20 years.
 Production at the mine is scheduled to start in 2015 following an 80% confirmation completion of the project on 31 Dec 2014.
 The first production of concentrate out of the mine is expected to be in the first quarter of 2016.
The Colomac Mine was a privately owned and operated open pit gold mine located 220 km northwest of Yellowknife in the Northwest Territories in Canada .
 The Colomac mine operated between 1990–1992, and 1994–1997.
 It was operated by Neptune Resources Limited that had little success in making a profit during its operation.
 In 1994, the mine had reopened under Royal Oak Mines Inc.
 Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte.
 Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy.
 The Federal Government of Canada became owners of the mine, along with the related environmental issues.
 A major cleanup effort is under way to prevent the mine from polluting the environment, but this might be too late at this stage.
 This mine is now owned and controlled by the Indigenous and Northern Affairs department of the Federal government, while Public Works and Government services is the current contracting authority.
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.
