The Wohlleben Creek diatomite showing is located in Wholleben Creek valley 5 kilometres above its confluence with the Loon Creek, twelve kilometres east of Clinton.

The occurence is hosted in the north draining Mio-Bonaparte channel, a fluviatile and lacustrine interlayer of the Miocene Deadman River Formation which is part of the Miocene to Pleistocene Chilcotin Group composed mainly of alkaline plateau basaltic flows. The Deadman River Formation (EMPR Open File 1989-21) is composed of rhyolite ash, tuffaceous sandstone, siltstone, shale, minor pebble conglomerate. The siltstones and shales are commonly carbonaceous and/or diatomaceous. Overlying the Deadman River Formation are extensive alkaline olivine basalt flows of the Chasm Formation which are also part of the Miocene to Pleistocene Chilcotin Group.

The Wohlleben Creek diatomaceous earth showing lies within 30 metres of the top of a Miocene channel filling of fluviatile and lacustrine sediments occupying the Mio-Bonaparte Channel which is over 5 kilometres wide and 400 metres deep.

The property was staked by Western Industrial Clay Products Limited in 1994, and four diamond drill holes bored (a total of 332.9 metres) to test the property (Assessment Report 23876). A 97.5 metre thickness of Deadman River Formation sedimentary material was encountered in diamond drill hole WOH#3. The drilling encountered an Upper and a Lower Diatomite section, each respectively an average of 2.6 and 5.0 metres in thickness.
