Report: Quote from Sassman (1941), "The Straight Tip group is comprised of five patented claims, four of which are contiguous on the vein. They are known as the Potomac, Mt. Vernon, Wabash, Good Hope, and Ranger. These claims are at the head of Swede Creek, which is southeast of Jackson, Montana, and near the Continental Divide. The stream is now named Jahnke Creek. The ore body was discovered in the early days by Frank Brown who had done considerable prospecting along the divide between Beaverhead County and Idaho. He also located the Ajax mine, which will be described later. Brown never staked the discovery for some unknown reason. When William P., August F., and John H. Jahnke were told by Brown about the existence of the mineral deposit, these brothers located it in 1898. The ore was mostly copper with some silver, gold and lead. At first the brothers used pack horses for a distance of three miles to a place where it was convenient to haul it by wagons. By this method a few tons of the ore were sent as an experiment to Salt Lake City to be refined. The ore netted from $43 to $47 per ton. F.K. Vial, a mining engineer from La Grange, Illinois, visited the Straight Tip claims in 1907 and stated "that numerous small veins and stringers were found, which indicated the existence of a large body of ore." Sassman goes on to describe the people who then owned the mine. Then he states "In 1908 about five miles of road were built to the mine at a cost of about $1000. The mines were equipped with a complete mining plant for quick and effective work, including a boiler, air compressor, Ingersoll drills, and other necessary equipment. The buildings at the mine included a power house. At one time about 24 miners were employed. During the period of exploration approximately 3,000 feet of tunnels and drifts were dug into the mountain to contact the vein. Funds gave out before the ore was reached and work was stopped. The company spent nearly $125,000 in this venture. The property was abandoned until recently when the mine was leased from John Rankin who had aquired it by paying the delinquent taxes." See also Geach, 1972, p. 36-38.
