The Horseshoe Bend alluvial, nephrite/jade showing is located on the west bank of the Horseshoe Bend in the Bridge River, as well as within Bridge River, 1 kilometre southeast of the mouth of Yalakom River. Rodingite as irregular masses outcrop on the river bank and is within sheared serpentinite of the Permian and older Shulaps Ultrmafic Complex. Nephrite is not found in place, but is present as boulders in the river. The nephrite is a hydrothermal alteration product of ultramafic rocks; the nephrite has subsequently been eroded and deposited in the river as alluvial boulders.
