The Patterson West project area is located over the mostly granitic Clearwater Domain, but the basement conductors interpreted form the VTEM survey and the presence of kaolinitic and hematitic mica schist in the last 35 metres of historical drill hole SAM15 indicates the presence of either a sedimentary package or a significant shear zone.

Curl and Franzmeier (1984) reported that goethitic soils adsorbed more P than hematitic soils in Brazilian Oxisols, which they considered to be a consequence of the larger crystal size of goethite relative to hematite.
