The Discovery Bar occurrence is located approximately 2 kilometres southwest of Manson Creek, along the Manson River near Discovery Bar.

The general area is within the Manson fault zone, a right-lateral fault, probably Late Cretaceous to Paleogene. This fault dissects rocks belonging to the Slide Mountain and Quesnel terranes.

The occurrence is hosted near one of the splays of the Manson fault zone, which separates black phyllites belonging to the Middle to Upper Triassic Slate Creek Formation (Takla Group), to the southwest, from quartz-carbonate–altered ultramafics (listwanite) belonging to the Pennsylvanian to Permian Manson Lakes Ultramafites to the northeast.

This occurrence consists of numerous parallel stringers, 6 to 12 centimetres wide, that occur (in part) en echelon within calcareous graphitic phyllites. These stringers occur in a zone that is 3.65 metres wide. Quartz veins and stringers in the general area are sparsely mineralized with galena, pyrite and sphalerite.

A grab sample analyzed 1.58 per cent lead, 41.1 grams per tonne silver and 0.49 per cent zinc (Geological Survey of Canada, Memoir 252-131).

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 in locating the quartz-vein–hosted coarse gold.
