The Felsenmeer occurrence is located 500 metres southeast of Boden Lake, about 92 kilometres southeast of Dease Lake.
In the area of the showing, upper Permian to Middle Triassic Kutcho assemblage mafic to felsic metavolcanic rocks and sediments underlie Upper Triassic Sinwa Formation limestone and Lower Jurassic Inklin Formation metasedimentary and sedimentary rocks. The area is interpreted to have been isoclinally folded during formation of the King Salmon allochthon in Early to Middle Jurassic time. The Inklin Formation has recently been reassigned to the Laberge Group (Overlap Assemblage), and the Sinwa Formation to the Stuhini Group (Stikine Terrane). See the Kutcho Creek deposit (104I 060) located 12.3 kilometres east for details of the new age dates for rocks of the Kutcho assemblage.
The Felsenmeer showing consists of fine grained, granular, bright pyrite grains disseminated in granular felsic feldspar porphyry tuff. This minor pyrite appears in the tuff where the unit thins out and terminates at its western end, sandwiched between underlying massive light grey limestone and overlying black thin-bedded siltstone.
Between 2008 to 2010, the occurrence was explored by Kutcho Copper Corp. as a part of the Kutcho property (Accent 1 claim). For a complete exploration history see Kutcho Creek deposit (104I 060) or Assessment Report 31282. In 2009, one grab sample assayed 58 parts per million (ppm) copper, 2.6 ppm lead, 139 ppm zinc, 0.16 ppm silver, and 0.1 ppm gold (Assessment Report 31282).
