At the Okay Mountain occurrence, one coal seam, approximately 30 centimetres thick, was encountered in 1 of 5 holes drilled in the area. The coal is interbedded with shale and sandstone of the Upper Cretaceous Comox Formation (Nanaimo Group) and appears to have limited continuity. A sample taken from the drillhole intersection of coal is composed entirely of wood fragments (65 per cent structured wood fragments and 35 per cent charcoal) and probably represents a deposit of rafted wood in a delta plain situation. The coal is ash-rich and contains high silica, sulphur, calcium, titanium, nickel and copper.

The structure in the area is complex and consists of a series of northwest and northeast trending normal faults. Strata trends northeast and dips 3 to 12 degrees southeast in the west and centre of the property. In the south, bedding trends northwest and dips northeast 5 to 12 degrees. At the southeast edge of the property strata strikes north-northeast and dips 5 to 6 degrees northwest. The variations in strike may be fault related or may represent a shallow northeast trending, northeast plunging faulted syncline.
