The JEA occurrence is located near the big bend of the Germansen River, approximately 8 kilometres northwest of the settlement of Manson Creek.

This occurrence is only described in Geological Survey of Canada Paper 41-5 as a quartz vein with tetrahedrite that assayed fair gold and silver values. This showing is located in argillites and altered ultramafics of the Mississippian to Permian Cooper Ridge Group and the Pennsylvanian to Permian Manson Lakes ultramafites. These rocks have been dissected by the right-lateral, northwest-striking, probably Cretaceous to Neogene Manson fault zone.

There are no other tetrahedrite-bearing veins known in the general area and this occurrence may be an early reference to the Motherlode and Flagstaff showing (MINFILE 093N 024) which contains tetrahedrite and is in the immediate area.

In 2017, Angel Jade Mines Ltd. carried out a field program with the intention of locating hard-rock sources of placer gold, and to determine if gold and base metal anomalies within the listwanite exposures could be used as a vector to high-grade mineralization. The field program focused on three regions within the Manson Creek area: the Big Bend area near the southern extent of the claim group, the Gary’s Pit area within the eastern extent of the claim group and the Blackjack Creek area within the northern extent of the claim group. Between the three regions, a total of 62 rock samples were collected and assayed. The assays returned no values of economic interest and it was suggested that future exploration would benefit from structural mapping to locate the quartz-vein–hosted coarse gold.
