The Lost Creek placer deposit is located on Lost Creek which is a tributary of the Manson River. This occurrence lies approximately 2.5 kilometres southeast of the settlement of Manson Creek. The occurrence location is near an old ditch on Lost Creek.

This occurrence lies near the Manson fault zone and the bedrock is predominantly slates and argillites of the Middle-Upper Triassic Slate Creek Formation of the Middle Triassic to Lower Jurassic Takla Group.

Gold was discovered on the Manson River in 1871 and from 1871 to 1897 placer operations on Lost creek were mainly concerned with the postglacial deposits in the creek bed. During the 1900s to the 1930s, Lost Creek was mined by both a hydraulic operation and by underground methods which consisted of four adits. In the late 1930s, Lost Creek Placer Gold Limited ran a shovel and dragline operation on Lost Creek.

Reported gold production by Holland, 1950 (Bulletin 28, page 45) is 11,384 grams; 3017 grams recovered between 1881 and 1885; and 8367 grams between 1936 and 1945.
