The Alaska-Gastineau Mine was located within the Silver Bow Basin. Its concentrating plant was situated near Thane.[4] The mine had a Шаблон:Convert shaft running through Mount Roberts that reached the Perseverance Mine near Gold Creek.[5] It adjoined the Alaska-Juneau Mine.[6] The mine's low-grade ore is situated on a mountain above the Gastineau Channel. Its ore body covered approximately Шаблон:Convert, more than Шаблон:Convert in length, with Шаблон:Convert of tunnels and crosscuts. According to Jackling, the block of ore had at least 100,000,000 tons above sea level.[6] The property consisted of a group of claims whose lode system covered Шаблон:Convert.[2] It was operated on a 6,000-ton daily capacity.[7]
History
The mine's large scale development began in 1912.[2] In 1913, while it was under construction, Emile Gastonguay was hired as the mine's chief electrician[8] by managing director, Daniel C. Jackling.[9]Bartlett L. Thane was the manager.[9] Becoming unprofitable, it was shut down in 1921.
Features
For a period of time preceding World War I, the Alaska-Gastineau Mine was the largest gold mine in the world.[3] Its mills were said to be the largest and most modern gold-crushing plant in the world.[6] For its time, the ore was handled more economically than in any other Northwest mine.[10] "The mill avoided chemical processing with cyanide (cyanidation) or mercury amalgamation circuits by smelting all the concentrate."[11]
