One coal seam, approximately 1.5 metres thick, outcrops at the northern part of the property. The seam is interbedded with sandstone and shale and occurs towards the top of the sedimentary section which is up to 275 metres thick. The remainder of the section consists pre- dominantly of conglomerate which is part of the Lower Cretaceous Skeena Group, Red Rose Formation.

The structure in the area consists of an approximately north- northeast north-northeast plunging syncline. The section appears to be relatively undisturbed by faulting. The coal seam is eroded to the south and a large extent of coal measures is unlikely to the north because the sediments are terminated by intrusives just north of the property boundary. Dips on the property are no greater than 25 degrees.
