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. [END] 
[1]  [DOC] 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. [END]
