Though Tiptop's brief life was overshadowed by activity at nearby Chafey (Dun Glen), it was actually here at the Black Hole Mine that E.S. Chafey made the gold discovery that revived the district. Chafey soon built a 30-ton mill, and by 1910 an estimated $300,000 was produced (mostly gold).

In 1929, the 30-ton mill was destroyed by fire. Not long thereafter, the Black Hole-Monroe property was acquired by the White Bear Mining Company, who began construction on a new 50-ton amalgamation and concentration mill in 1932. Met with financial difficulties, the mill wasn't completed until March 1935, and even then only ran for a few weeks before being shut down.
