The Sat occurrence is located on the north eastern shore of Hesquiat Lake, approximately 600 metres north east of the Satchie Creek mouth.

In the Hesquiat Lake area, northwest striking limestones and volcanics previously assigned to the Quatsino and Karmutsen Formations (Geological Survey of Canada Map 53-17) have more recently been included with the Pennsylvanian to Permian Sicker Group (Geological Survey of Canada Map 1537A). These rocks are intruded by felsic granitic rocks of the Early to Middle Jurassic Island Plutonic Suite (Muchalat Batholith). A dioritic to gabbroic border phase is 500 metres wide.

Locally, a small area of skarn along a Permian-Pennsylvanian Sicker Group limestone-greenstone contact lies near granodiorite of the Jurassic Island Plutonic Suite. The occurrence is indicated as an iron occurrence (Assessment Report 462). It may coincide with the indicated "pits in manganese-bearing, wollastinite skarn" on the east boundary of Hesquiat 21 claim (Assessment Report 464, Figure 4).

In 1962, Paco Resources completed a program of geological mapping and a ground magnetometer survey on the area. In 1969, Lindale Copper completed a program of geological mapping, soil sampling and a ground magnetometer survey.
