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

It is exposed on the coast in southern Hampshire and in the northern part of the Isle of Wight. The type section is sea cliffs east of Christchurch, between Cliff End and Paddy's Gap.
