Question: Which Canadian mine was a goldmine, out of the Kemess Mine in British Columbia and Ontario's Temagami-Lorrain Mine?
Context: Temagami-Lorrain Mine is an abandoned surface and underground mine in Northeastern Ontario, Canada.  It is located about 10 km northeast of the town of Temagami near Sauvé Lake in central Cassels Township.  It is named after the Temagami-Lorrain Mining Company, which carried out work on the property in the early 1900s. Sustut Peak, 2481 m (8140 ft), prominence: 1231 m, is the highest summit in the drainage of the Sustut River in British Columbia, Canada.  Located in the Hogem Ranges west of Sustut Lake, which is at the Sustut River's headwaters, it is 8 km southwest of the road to the Kemess Mine The Hedley Mascot Mine was a gold mine in Hedley, British Columbia, Canada.  Gold was first discovered in the Nickel Plate Mountain area in 1897 and several small mines were developed over the years.  The Hedley Mascot Mine operated between 1936 and 1949 and was one of the most unusual mining operations in the world, being built entirely on the side of a mountain, 5,000 feet above the town of Hedley or seven thousand feet above sea level.  In the 1990s, the British Columbia government was going to burn the site down because it posed a safety risk, but the Minister of Tourism at the time intervened and, in 1995, steps were taken to preserve the site as a Provincial Heritage resource. Kemess Creek Airport, (TC LID: CBQ7) , is located near Kemess Mine, British Columbia, Canada. Pitt Lake's Lost Gold Mine is a legendary lost mine said to be near Pitt Lake, British Columbia, Canada, the supposed wealth of which has held the imagination of people worldwide for more than a century.  Ever since the years of the Fraser Canyon Gold Rush prospectors and adventurers have been looking for the mine and gold-rush rumors have evolved into legends repeated and enriched over time.  The mysterious riches are known as Slumach’s Lost Mine, or Lost Creek Mine. Thompson Creek Metals Company Inc. is a full cycle mining company with acquisition, exploration, development, and operation in North America. </small> The corporate office is located in Denver, Colorado.  The company primarily produces copper, gold, and molybdenum. </small> In the past several years, the Company has evolved from being a major primary molybdenum producer to becoming a copper and gold mining company with the construction and development of the Mount Milligan (open-pit copper-gold) mine and concentrator in British Columbia, Canada.  Mount Milligan is Thompson Creek Metals principal operation and the company owns 100% of this property. </small> The company also owns 100% of its Thompson Creek Mine (open-pit molybdenum and concentrator) in Idaho.  Thompson Creek Metals owns 75% joint venture interest in two other properties, including its Endako Mine (open-pit molybdenum, concentrator and roaster) in British Columbia, and its Langeloth Metallurgical Facility (roaster) in Pennsylvania. </small> Thompson Creek Metals has additional development projects, including the Berg property in British Columbia (exploration of copper, molybdenum, and silver). </small> </small> Thutade Lake is located in the Omineca Mountains of the Northern Interior of British Columbia, Canada.  About 40 km in length, and no more than about 2 km wide, the lake is primarily significant as the ultimate source of the Mackenzie River.  The lake is at the head of the Finlay River, which joins the Peace River via Williston Lake.  The area is very remote, being located about 260 km north of Smithers, although several mining operations for ores containing copper, lead, zinc and silver have occurred around the lake.  The largest of these is the Kemess Mine, an iron and copper property originally owned by Royal Oak Mines and now by Northgate Minerals, located in the valley of Kemess Creek, which is off the northeast end of Thutade Lake.  The mine is accessed by the Omineca Resource Road and other resource routes, and is 400 km by road from Prince George.  Just downstream from the outlet of Thutade Lake, the Finlay plunges over 180 ft Cascadero Falls, and then through a series of cataracts in a twisting course until it begins its main northeastward trend.  Cascadero Falls is slated for hydroelectric development in connection with the power needs of the area's mines. Cascadero Falls is a waterfall on the Finlay River in the Northern Interior of British Columbia, Canada, located just below that river's head at the outlet of Thutade Lake.  The height of the falls is 180 ft and below it there are numerous cascades or rapids in a twisting course prior to the river's general northeastward trend from this area.  The falls are slated for hydroelectric development in connection with the area's mines, the largest of which is the Kemess Mine owned by Northgate Minerals Inc., located just east of the foot of Thutade Lake in the valley of Kemess Creek. Cassiar is a ghost town in British Columbia, Canada.  It was a small company-owned asbestos mining town located in the Cassiar Mountains of Northern British Columbia north of Dease Lake.  After forty years of operation, starting in 1952, the mine was unexpectedly forced to close in 1992.  The closure was driven by a combination of factors including diminished demand for asbestos and expensive complications faced after converting from an open-pit mine to an underground mine.  Most of the contents of the town, including a few houses, were sold off and trucked away.  Most of the houses were bull-dozed and burned to the ground.  The mill was briefly reactivated in 1999 by Cassiar Chrysotile Inc which had a reclamation permit to clean up the site.  11,000 tons of asbestos were exported before the mill burned down on Christmas Day of 2000, effectively halting all production.  Today the streets are bare and flowers bloom where the houses once stood.  Residents living between the townsite and the Stewart-Cassiar Highway, and on the highway itself, who originally obtained phone service from the Cassiar exchange, were moved to the nearby Good Hope Lake exchange in fall 2006 and the Cassiar exchange shut down. The Kemess Mine was an open-pit copper and gold mine, located just northeast of the foot of Thutade Lake, at the head of the Finlay River, in the Omineca Mountains of the Northern Interior of British Columbia, Canada.  It was operated by Royal Oak Mines from 1998 to 1999, when it was bought by Northgate Minerals.  Northgate operated the mine until its closure in 2011; that year Northgate was taken over by AuRico Gold.  In 2014 AuRico Gold partitioned off its portion of kemess Mine ownership creating a new company called AuRico Metals.  AuRico Metals is actively implementing permits for a block caving mine.
