The Phoenix Mining Company was organized in 1849 and took over the mining operations of the Lake Superior Mine on the Eagle River. In 1863, the company began focusing on rich copper fissure veins that were located to the south along the bluffs adjacent to the Cliff Mine. The company immediately sank two shafts (Tyler and Crocker) directly on top of the bluff. That same year (1863), over 244,000 pounds of copper ingots were produced. Between 1866 and 1869, 530 tons of copper ingots were produced from the Phoenix Vein. In 1869, the company reorganized into the Phoenix Copper Company and was operating on five veins (Phoenix, East Phoenix, Armstrong, Ward, and Robbins) as well as the Ashbed Amygdaloid. In 1871, the company purchased the Bay State property. That same year, the company reorganized again as the Phoenix Consolidated Copper Company. This new company controlled the Phoenix, St, Clair, Garden City, Meadow, and Atlas Mines. In 1875, the Phoenix and Robbins (West) Veins produced over 4,300 ounces of silver, and between 1880 and 1881, the mine produced 503 tons of copper ingots. The Phoenix Consolidated reorganized for the final time in 1899 under the same name. A company report lists operations were confined to the St. Clair and West Vein properties. By 1901, most production was coming from the St. Clair Fissure with very little from West Vein. A 1905 company report stated that because conditions at the St. Clair shafts were not conducive to work greater depths, the company began selling off stock and mining equipment. In 1905, the Phoenix Mine became part of the Keweenaw Copper Company and by 1923, Keweenaw owned all of the Phoenix properties and the company was dissolved. Beginning in 1927, Calumet and Hecla began dewatering and repairing two of the Phoenix shafts but by 1929, all work ceased.

Today, the Phoenix piles are accessible, but are on private property and premission must be obtained before entering. If permission is granted, copper, silver, prehnite, and pumpellyite can be found.
