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.
La Grange Mine The La Grange Mine is a former mine located in Trinity County, California. At one time it was the largest hydraulic mine in California. Started operating in 1862, over 3,500,000 dollars of gold was extracted before it was closed down in 1918 due to rising costs of labor and steel after World War I. The quality of gold was low so hydraulic mining was used to take it from the ground. The site is now a California Historical Landmark.
