The Tatsatua occurrence is located at the junction of Tatsatua Creek and the main tributary from Tatsamenie Lake, approximately

The area is underlain by Lower or Middle Jurassic Laberge Group shale, siltstone, and limestone, which have been intruded by a Cretaceous or Tertiary quartz monzonite stock and by felsite dikes.

Locally, a strong northwest trending shear forming the contact between a quartz monzonite body and sediments host pyrite and arsenopyrite mineralization as massive aggregates in 10 to 15-centimetre lenses. The shear zone is intensely brecciated and varies in width from 0.5 to 2.0 metres wide.

In 1982, Chevron Resources completed a regional soil survey on the area and identified an area of anomalous gold and arsenic results. In 1991, Pacific Century Explorations completed a program of prospecting and soil, silt, and rock sampling. Sampling of the showing returned up to 0.53 gram per tonne gold (Assessment Report 22210).

From late 2013 to date (February 2020) IMGM International Mining Canada Inc. held a large group of claims totalling 23313 hectares that stretched west from Trapper Lake east to the Sheslay River and south from Kowatua and Tatsatua creeks. The exploration work was focused primarily on the Tats zone (104K 155). In 2016, IMGM collected 313 stream silt samples and 75 rock samples across there property. A number of the silt samples were collected in the area of the Tatsatua showing (Assessment Report 35006).

See the Tats zone (104K 155) further details.
