The Lost Creek Lead occurrence is located approximately between Lost and Skeleton creeks, just south of the Manson River. It is located on an old description of a pre-1938 adit.

The only references to this occurrence is from two Minister of Mines Annual Reports (1938 and 1928). It is described as a number of lenticular quartz veins, 15 to 75 centimetres in width, occurring within hydrothermally altered bands of grey to black fissile limestones and argillites of the Middle to Upper Triassic Slate Creek Formation (Takla Group). These galena and pyrite-bearing veins strike northwest and dip steeply. Where located, this occurrence is within the right-lateral, northwest-striking Manson fault zone.

In 2006, Spanish Mountain Gold Ltd conducted a comprehensive soil and silt sampling program on the MC property within the Manson Creek area covering approximately 54 000 hectares. In total, 962 soil samples, 52 silt samples and 52 heavy mineral samples were collected.
