Question: Which was halted by a natural disaster, Camlaren Mine or Barton Mine?

full_context: Document 1: Northland Pyrite Mine: The Northland Pyrite Mine, also known as James Lake Mine, Rib Lake Mine, Harris Mine or simply Northland Mine, is an abandoned underground mine in Northeastern Ontario, Canada, located on the southwestern shore of James Lake in Best Township of Temagami. It was operated by the Northland Mining Company during the early 1900s with the construction of a 91 m shaft and many open-cuts north of the shaft. Minerals present at the mine include chalcopyrite, pyrite and pyrrhotite, deposited in Precambrian volcanic rock of the Canadian Shield.
Document 2: Colomac Mine: 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.
Document 3: Minto City: Minto City, often called just Minto, sometimes Minto Mines or Minto Mine, was a gold mining town in the Bridge River Valley of British Columbia from 1930 to 1936, located at the confluence of that river with Gun Creek, one of its larger tributaries. It was first called the Alpha group of claims in the 1920s, when underground miners were exploring the seams of Cadwallader Creek and the origins of the placer deposits downstream in the Bridge River. The mine prospect was never much successful although a model townsite was built by promoter "Big Bill" Davidson, who imported soil to build a specially-built rodeo ground and baseball diamond on the rocky site. The larger mine of Bralorne was nearby. The mine shut down in 1936 due to productivity issues, but restarted in 1940. The valley has since been significantly altered when most of the vestiges of the town were inundated by the waters of the Carpenter Lake reservoir following completion of the Bridge River Power Project. The town sat on the western end of the lake near the present Carpenter Lake Road (a section of BC Road 40), part of the road drove through a wooden Tudor arch built into the rock mill.
Document 4: Ptarmigan and Tom Mine: 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).
Document 5: Kanichee Mine: The Kanichee Mine, also less commonly known as the Ajax Mine, is an abandoned base metal and precious metal mine, located in the Temagami region of northeastern Ontario, Canada. It is near the small unincorporated community of Temagami North, accessed by the Kanichee Mine Road from Highway 11. The Kanichee Mine zone has been explored and mined discontinuously from as early as 1910. During the 20th century, it operated and closed down at least three times, with the most recent being from 1973 to 1976. To date, the discontinuous operation of Kanichee Mine has produced 4.2 million pounds of metal.
Document 6: Norrie Mine: Norrie Mine is an abandoned surface mine in Northeastern Ontario, Canada. It is located about 1 km northeast of Temagami North on the eastern shore of Net Lake in eastern Strathy Township. It is named after L. B. Norrie of New York, who first claimed the mine site.
Document 7: Barton Mine: Barton Mine, also known as Net Lake Mine, is an abandoned surface and underground mine in Northeastern Ontario, Canada. It is located about 0.50 km north of the Temagami Arena in Temagami North and just east of the Ontario Northland Railway in northwestern Strathy Township. Dating back to the early 1900s, it is one of the oldest mines in Temagami. Barton was the site of a fire in the early 1900s, after which it never had active mining again.
Document 8: Ptarmigan and Tom Mine: 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).
Document 9: Thompson-Lundmark Mine: 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.
Document 10: Tetapaga Lake: Tetapaga Lake, also known as Lake Tetapaga, is a narrow east-west trending lake in the Temagami region of Northeastern Ontario, Canada, located at the abandoned iron-bearing Sherman Mine. A gravel road crosses the central portion of the lake, splitting it into two small lakes. The eastern half of Tetapaga Lake is somewhat green in colour due to acid mine drainage water flowing into the lake. The acid mine drainage water results from water seeping through the abandoned iron ore of Sherman Mine along its eastern shore. Its western half is relatively uninfected where very little waste from Sherman Mine exists.
Document 11: 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.
Document 12: Temagami-Lorrain Mine: 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.
Document 13: Ruth Mine: The Ruth Mine was a small gold producer about 65 km (40 miles) east of Yellowknife, Northwest Territories. It operated briefly during 1942 and then again in 1959, extracting only 550 troy ounces (17 kg) of gold thus far. The old mine is today (2012) significant as one of the last intact abandoned mining properties from the 1940s period in the Northwest Territories, although the site was scheduled to be remediated by the federal government.
Document 14: Camlaren Mine: 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.
Document 15: Copperfields Mine: Copperfields Mine, originally known as Temagami Mine, is an abandoned copper and silver mine on Temagami Island in Lake Temagami, Ontario, Canada. The mine opened in 1955 and comprises both underground and surface workings within a sulfide ore body. Situated in Phyllis Township, the mine produced 34,000,000 dollars Canadian with 80 million pounds of copper, 230,028 ounces of silver and 13,271 ounces of gold. It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada. A mill was not initially needed because the ore was 28% copper. The mine closed in 1972 and is now flooded by water. Ruins of the Copperfields mill are present as foundations. It is possible to find mineral specimens in the spoil heaps of the old mine, such as chalcopyrite, pyrite, bornite, malachite, dolomite, hessite, merenskyite, millerite, palladium, quartz and others. The Lake Temagami Access Road was created to ship ore from the mine site.
