Report: The Jumbo group was also known as the Tip Top (Gibson, 1948) and also the Blacktail and the New Deal properties (Johns, 1970). In 1998, three adits were open but secured with chainlink and barbed wire. Two other adits were partly open and one was completely caved. An adit downhill from the trail had caved and was eroding away the trail.An aerial tramway was described in Gibson (1948) and the remains of a concrete and rock base was found in front of one of the adits. The cable from the tramway stretches down to just east of the American Kootenai mine. The adits were fairly short (+/- 300 feet) but there were several along the same horizon. Minerals associated with the Tip Top or Jumbo include quartz, sericite, sphalerite, pyrite, pyrrhotite, and iron oxides (Gilbert, 1948). The host rock is Prichard argillites and sandstones.
