The Germansen River South occurrence is located on the east bank of the Germansen River (just north of the big bend) approximately 8 kilometres northwest of the settlement of Manson Creek. This occurrence encompasses all the workings along the Germansen River except for the Germansen pits (093N 054).

Placer gold was first discovered on the Germansen River in 1870. The northwest-trending part of the River (from its mouth to the big bend area) has been the area most explored and placer mined. Numerous workings have occurred along the Germansen River and have a long and productive history. Travelling along the main road, cliff faces and pits expose thick volumes of unconsolidated material. These topographic features are the result of past placer mining practices. During the 1930s to the early 1940s, the hydraulic method of placer mining was the most common.

Just north of the big bend area, the bedrock is cut by the Manson fault zone, and consists of slices of Pennsylvanian to Permian Manson Lakes ultramafites, the Mississippian to Permian Cooper Ridge Group and rocks belonging to the Middle Triassic to Lower Jurassic Takla Group. The most predominant rocks to the southwest of the fault zone are argillites and slates belonging to the Takla Group.

Placer deposits can be found on low-lying benches and in the bed of the river, on rock benches that lie approximately 10 metres above the river, and in deeply buried channels below the river level. Most of the workings are related to the rock benches that lie above the river. These rock benches are overlain by auriferous fine and coarse gravels and sand that are somewhat cemented. The semi-cemented gravel and sand is overlain by approximately 15 metres of coarser gravels and boulder clay. The gravels lower and near to the top of the semi-cemented gravel and sand are also auriferous. The gold is mainly coarse, nuggety and somewhat flat.

During the 1988 field season, a sluice box operation mined material from a low-lying bench near the river, just north of the big bend in the Germansen River.

Prior to 1950, reported gold production for the entire Germansen River varies from 515 851 grams (Bulletin 28, page 43) to 750 776 grams (Geological Survey of Canada, Memoir 252, page 145). Most of this gold recovery was achieved between the years 1876 and 1890, and between 1931 and 1945.

Work History

In 1980, Taiga Consultants Ltd. completed a work program of geological mapping, 28 line-kilometre geophysical and ground magnetic survey and a geochemical program consisting of 1022 soil samples and 35 rock samples within the Opec and Flume claim groups.

In 1982, Anaconda Canada Exploration Ltd. carried out a program of geological mapping, 990 soil and 222 rock samples, ground very low frequency and magnetometer surveys over 72.5 line-kilometres, and trenching on the OPEC and QCM claim groups.

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.
