Jumbo Mine

Though the Slumbering Hills had seen a lull in activity since about 1918, they were awoken in February 1935 by J.C. Stagg and Clyde Taylor's discovery of the Jumbo Mine. By the end of the year, the mine was sold to George Austin and associates of Jungo, who built a small amalgamation mill and obtained some high-grade ore. The next year, a thirty-ton amalgamation concentration mill was erected, which produced over 1000 tons in the first five months of 1937. A visit by ex-President Herbert Hoover brought further attention to the mine, and though a new rush to the district was underway, only the Jumbo was a sustainable producer.

In May 1937, J.K Wadley and H.L. Hunt, oil operators from Texas, secured a 35-year lease on the mine with the option to purchase it within twenty years, but due to litigation this never happened and the mine reverted to the original owners. Production halted during World War II, but thereafter a 500-ton per day pit was put into operation for less than a year; only intermittent work has occurred since.
