Question: Both the Discovery Mine and the Camlaren Mine are located near Yellowknife, Northeast Territories, but which is closer?
Context: The Jericho Diamond Mine is a dormant diamond mine located in Canada's Nunavut territory.  Jericho is Nunavut’s first and only diamond mine.  It is located 420 km northeast of Yellowknife, Northwest Territories and is accessible by air all year and by winter road from Yellowknife.  The project was mined from 2006 to 2008, and produced 780000 carat of diamonds from 1200000 t of kimberlite mined from the open pit operation.  Over $200 million was invested in the development of the Jericho operations including the construction of a 2000 t per day diamond recovery plant, maintenance facility, fuel farm, and offices and accommodation for 225 personnel. The Burwash Mine was a small gold property discovered in the fall of 1934 by Johnny Baker and Hugh Muir at Yellowknife Bay, Northwest Territories.  The town of Yellowknife did not exist yet at that point, but the discovery of gold at Burwash was the catalyst that brought more gold prospectors into the region in 1935 and 1936.  A short shaft was sunk in 1935-1936 at Burwash, and in the summer of 1935 a 16-ton bulk sample of ore was shipped to Trail, British Columbia for processing, yielding 200 troy ounces (6 kg) of gold.  The mine did not become a substantial producer and it is believed the gold vein was mined out. 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. The Camlaren Mine was a small gold mine 80 km north-east of Yellowknife, Northwest Territories, Canada at Gordon Lake.  It consists of a property totaling about 981 hectares.  The two claims that make up the property were staked in 1936 by prospectors Don Cameron and the Mclaren brothers and developed with two shafts during 1937-1938.  The name "Camlaren" is a portmanteau of Cameron and McLaren.  Conditions attributed to World War II halted development at Camlaren in 1939. 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 Discovery Mine was a gold mine 81 kilometers northeast (approx bearing of 15 degrees) of Yellowknife, Northwest Territories that operated between 1950 and 1969.  Gold was discovered here by Alfred Giauque in 1944.  A complete townsite, on Giauque Lake, was established by the company to house workers and their families.  The mine produced one million troy ounces (31,000 kg) of gold from one million tons of ore.  The abandoned townsite, not accessible by road, was demolished in 2005. 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. The Beaulieu Mine was a post-World War II gold mining operation near Yellowknife, Northwest Territories.  It entered production in October 1947, but by the end of November only 7 troy ounces (220 g) of rough gold were recovered.  Additional gold was recovered during 1948, but altogether the mine recovered only 30 troy ounces (930 g) of fine gold.  The operation folded in chaos and bankruptcy. 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. The Bank of Toronto is a historic cabin located in Old Town, Yellowknife, Northwest Territories, Canada.  The log cabin was constructed in 1939 by John Stakson an expert log builder in the commercial district of the Yellowknife community for use as a residence.  In October 1944, the Bank of Toronto purchased the cabin and opened a new bank for the community, joining the Bank of Commerce (Yellowknife's first bank in 1938).  The bank arrived in Yellowknife in response to new financial activity brought about by the intersection of gold in shear zones at Giant Mine and the resulting staking spree around the region.  As the gold rush ended, the volume of business was insufficient to keep the bank profitable, and the Bank of Toronto closed this branch in August 1951.
Answer: Camlaren Mine
