A few small outcrops of serpentinite of the Permian-Jurassic Bridge River Complex appear to lie in a north-northeasterly trending zone extending from the head of Texas Creek to its mouth on Fraser River. Reports of nephrite near the head of the creek have not been confirmed but contact reaction zones with some nephritic selvages were seen on Lot 237 along the lower reaches of the creek above the Texas Creek road (Geological Survey of Canada 78-19, page 21).
