Ground was broken on the millsite on October 31, 1913. The land had been cleared previously and tramways erected for handling construction supplies. The first of four sections of the mill was completed February 12, 1915, commencing operations. By Ovember 1915, all four sections of the mill were in operation and treating 6000 tons of ore daily. The entire mining industry watched the Gastineau in amazement. The value of the stock rose from $10/share when initially issued in 1912, to $24/share while in the construction state in 1914, to $40.75/share in 1915.

The mill continued to set records until World War I depleted the company of its manpower. Post war inflation and gold prices set at $20.67 per ounce forced the mind to close in 1921. The facilities were scrapped and salvaged. What you see today is all that is left of the great Alaska Gastineau mine that recovered 500,00 ounces of gold from 12 million tons of ore.
