Tungsten ore was discovered at the Nightingale mine in 1917 by Alex Ranson and associates, and for two years small amounts were shipped to the mill at Toulon. In 1929, the property was acquired by the Gold-Silver-Tungsten Mining Co., who erected a 100-ton concentrator, though it only operated intermittently before finally closing in 1939. The district's mines (including the Alpine & Pershing) were purchased by the Rare Metals Corp. in 1943 and worked during World War II & the Korean War, but all work finally ceased in 1956.
