The Jessie showing is located 35 kilometres south of Carcross, Yukon Territory, at the southeast end of Tutshi Lake. Charter helicopters are available at Whitehorse, Yukon Territory, and at Atlin, located 70 kilometres to the east. Convenient boat access can be gained from the South Klondike Highway.
The area is underlain by the Devonian to Middle Triassic Boundary Ranges Metamorphic Suite, consisting, in this area, of greenstone and greenschist. These have been intruded by Late Cretaceous granites and alkali feldspar granites of the Coast Plutonic Complex.
A shear zone 1.8 metres in width occurs in andesite of the Boundary Ranges Metamorphic Suite near the eastern edge of the granitic intrusions. The shear zone strikes northeast and dips 65 degrees north. Mineralization consists of chalcopyrite and pyrrhotite with some galena and minor sphalerite. An average assay of the "ore shoots" in the zone is reported to be 5.14 grams per tonne gold, 809.14 grams per tonne silver and 4.9 per cent copper (Minister of Mines Annual Report 1929, page 120).
In 1906, the Jessie showing was originally staked as the Great Northern group by J. Bussinger. Exploration of the showing was limited to hand and blast trenching and was not reported until 1929, when a group of engineers from Timmins, Ontario expressed an interest in the property. In 1981, Dupont and Kennco staked the area between Tutshi Lake and Moon Lake, based on encouraging results from a regional geochemical survey in the area. During the field season, a program of geological mapping, soil -, silt - and rock sampling was conducted, and some strong anomalies were outlined within the Tutshi 1 claim (Assessment Report 10424). Although more work was recommended, the claims were allowed to lapse. In 1985, Noranda staked the area northeast of the Tutshi 1 claim as part of their Moon Lake Project. The Tut claims were staked in 1986 and 1987 by Noranda to cover a large alteration zone and the source areas for gold-bearing float. The claims cover the Jessie/Great Northern and Big Thing (104M 071) showings. A 1987 geophysical program identified an anomaly on the Tut 7 and 8 claims that appears to be on strike with the Moon Lake showing (104M 057) to the southwest. The anomaly was tested by diamond drilling in 1988 but the results were negative. Noranda have completed an airborne electromagnetic-magnetic survey, ground geophysical surveys, soil - and stream sediment surveys, geological mapping, and prospecting in the area south of Moon Lake. In 1988, as part of an integrated geoscientific survey, the Geological Survey Branch of the British Columbia Ministry of Energy, Mines and Petroleum Resources collected two silt sediment samples from streams which drain the property. In 1994, R. McMillan and R. Keefe staked the Tutshi property covering the Jessie showing and took 1 rock sample and 19 stream silt samples.
