The French showing is located at about 1710 metres on the summit of Mount Kobau, 520 metres west of the radio communication tower and 1.3 kilometres northwest of the Mak Siccar occurrence (082ESW004). The showing was located during reconnaissance mapping in 1990 by Azimuth Geological Inc., approximately 50 metres east of a radio communications tower.

Regionally, the French showing is hosted by polydeformed regionally metamorphosed sedimentary and volcanic rocks of the Carboniferous to Permian Kobau Group. The aereal distribution of Kobau Group rocks is restricted by the Similkameen River to the west and the Okanagan fault to the east. Intruding these rocks are small granodiorite plugs of the Middle Jurassic Similkameen intrusion, lying along the Manery Creek fault. A pluton of the Similkameen intrusion is located 1.5 kilometres to the southwest. Post-Middle Jurassic pyroxenite is also found at the Mak Siccar deposit.

The Kobau Group rocks have been subdivided into up to nine units. However, these generally consist of chlorite schist, foliated greenstone and lesser quartz sericite schist. The Kobau Group rocks have a northwest trending schistosity as well as a major northwest trending fold axis. Shears cut these rocks in three directions: north-south on the eastern portion of the property, and northeast and northwest to the west.

The French showing consists of a 30 by 15 metre outcrop hosting a quartz vein stockwork. The stockwork cuts limonite-altered quartzite along a strike of 230 to 255 degrees. The veins commonly carry pyrite. Heavy manganese staining covers the lower portion of the outcrop. The best geochemical gold results were from grab sample 105904 which yielded 0.03 gram per tonne gold (Assessment Report 20638). Chip sample 105675 yielded 0.02 gram per tonne gold over 1.8 metres (Assessment Report 20638).
