Report: Quote from Sassman (1941), "The Dark Horse Mine is on the Continental Divide between Montana and Idaho. This property is near the head of Mulky Creek, now called Dark Horse Creek, and a short distance north of the Goldstone mine. At one time the region was called the Mulky Mining District. Fred Stewart was one of the owners in 1902. In March 1906 the Calumet-Montana Mining Company, a Duluth concern, was organized with a capitol stock of $300,000, and took over the mine. J.A. McFadden was the manager and thirty-six men were employed at mining, putting up two steam boilers, and running the water-powered sawmill which supplied the necessary lumber for the mine and buildings. In the fall of 1906 William Dugan, the superintendent, had thirty-three men at work and shipped twelve tons of ore per week. J.H. Lanyon became the superintendent, but later resigned and T. J. Whitney took his place. In 1909-1910 and interstate tunnel, 2,935 feet long, was driven through the crest of the Continental Divide so that the ore could be hauled out by way of Salmon, Idaho. Many tons of ore were taken through this tunnel for shipment. In 1911 the principal officers were E.L Brown, president; H.J. Neiler, secretary; and A.C. O'Leary, managing director. Considerable mining was done under their supervision. However, the isolated of the mine caused the Dillon news organization to give incomplete and scattered accounts. These meager items also resulted from the fact that the ore was hauled west into Idaho. The company had two Erie City sixty-five horsepower boilers, a double Ledgerwood hoist, sawmill, blacksmith shop, barn, and all the necessary camp buildings. The Dark Horse property now consists of six patented claims: Dark Horse, number one, two, and three, Copper Stone, Roy B., and Alta D. The workings produced mainly copper with some lead, silver, and gold. These mines are idle at present. In 1914 the Rabbit Foot mine, which is in the vicinity of the Dark Horse, was owned by Frank Schmidt and Al Pritchard. Their mine was "adjacent to the Goldstone mine, the latter which, since its discovery, had produced for the owners, the Geiss brothers of Great Falls, $310,000 in ore." The Goldstone mine is on the crest of the Continental Divide. The main tunnel was dug from the Idaho side into the ore. All thse mines are now idle."
