The Tchentlo Lake occurrence is situated east of the north end of Tchentlo Lake, approximately 55 kilometres southeast of Takla Landing. The area was explored for its mercury potential during the Second World War.

The area is predominantly underlain by limestone assigned to the Carbonaceous to Jurassic Cache Creek Complex in contact with volcanics of the Middle Triassic to Lower Jurassic Takla Group along a north-northwesterly trending section of the Pinchi fault zone.

Early reports describe a few "specks" of cinnabar mineralization hosted by silicified limestone approximately 800 metres east of the lake.

No recent information concerning this occurrence is available.
