Thorite is reported to occur at the junction of Snow Creek (Arrow Creek) and Goat River. The area is underlain by argillite and quartzitic wacke metasediments of the Helikian Aldridge Formation (Middle Proterozoic Purcell Supergroup: Brown et al., Fieldwork 1994).
During 2004 through 2012, Eagle Plains Resources Ltd. completed programs of geological mapping, geochemical (soil and rock) sampling and airborne geophysical surveys on the area as apart of the Iron Range property. A completed property exploration history can be found at the O-Ray (MINFILE 082FSE017) occurrence.
