Work History
Originally staked as Jack claim (16136) in Mar/25 by J. McLean who performed hand trenching in 1926. Restaked as Ram claim(s) (82346) by P. Callison and L. Brown in Aug/62. No work was ever recorded.
Capsule Geology
The occurrence area is located at the southern end of Settlement Ridge, between Settlement and Carpenter Creeks, approximately 37 km due north of McQuesten Lake. The area was regionally mapped by L. Green (1972) of the Geological Survey of Canada in 1961 as part of a helicopter-supported party known as Operation Ogilvie. Although the area has not yet been remapped by the Yukon Geological Survey, C. Roots of the Geological Survey of Canada under contract with the Exploration and Geological Services Division (now part of the Yukon Geological Survey) remapped adjoining topographic map sheets 106D/8 and 106D/7 (East half) in 1990 and topographic map sheet 105M (1997) in the mid-1990's. D. Thorkelson (2000) also under contract with Exploration and Geological Services Division remapped topographic map sheet 106D/16 to the north as part of a larger bulletin. The work of these geologists was incorporated into a geological compilation of the Yukon released by Gordey and Makepeace of the Geological Survey of Canada in 2003.
Based on the work of these geologists it is believed that the occurrence area is underlain by Lower Proterozoic Gillespie Lake Group dolomite which has been intruded by Middle Proterozoic resistant dark weathering diorite and gabbro sills and dykes assigned to the Hart River Sills.
This occurrence is underlain by geology similar to that which underlies the neighboring Carpenter and Silver Hill occurrences (Minfile Occurrences #106D 040 and 042) located 5 km to the west. At these occurrences, Gillespie Lake Group dolomite hosts lead-zinc-silver mineralization which is inferred by Abbott (1991) to be a Mississippi Valley-type replacement deposit of Proterozoic age, similar to the Blende deposit (Minfile Occurrence #106D 064) which lies 30 km to the east. It is probable that the Settlemeir occurrence (this occurrence) was staked as a possible strike extension to the mineralization located to the immediate west.
