176 The 1946 Annual Report of the Minister of Mines for British Columbia states that the main entry is in about 540 feet, and that because of a fault and flow of water at the face, preparations were under way to reach the seam at a lower elevation. The 1947 report states that a slope was started on the west bank of King Creek to open up the seam previously marked in the east bank of the creek. DUNLEVY CREEK-CUST CREEK AREA The Dunlevy Creek-Cust Creek area includes the west side of Butler Ridge and the southern parts of the valleys of Dunlevy, Gravel Hill, and Cust Creeks. A reconnaissance examination of this area was made by ¥F. H. McLearn and E. J. W. Irish in 1948, and the following information is from their report (1944): “Butler Ridge is underlain by the Dunlevy formation, and the lower parts of Dunlevy and Gravel Hill Valleys by the Gething formation. Both formations are exposed in the Cust Valley. The structure includes the steep west limb of a flat-topped anticline on the west side of Butler Ridge, and the more gentle slopes of the same limb in Dunlevy and Gravel Hill Valleys. Dips on Butler Ridge are from 40 to 70 degrees southwest, and in Dunlevy Valley from 2 to 5 degrees southwest. The structure on Cust Creek is faulted and dips are less regular. Coal Seams “No seams thick enough to mine are exposed in the canyon of Dunlevy Creek, or in the canyon or upper reaches of the east fork of Dunlevy Creek and its tributaries. Only thin seams were found on Gravel Hill and Cust Creeks. “At and near the Packwood mine, at the south end of a spur from Butler Ridge, two thin seams occur in the upper conglomerate-bearing part of the Dunlevy formation. “The No. 1 seam, worked in the mine, has an average thickness of 30 inches in the upper level and 20 inches in the lower level. The lower 10 inches of the seam is finely crushed, and movement is also indicated by slickensides on both walls. The foot-wall rock is silty shale and the hanging-wall consists of hard, massive sandstone. The seam was sampled at the face in both levels.
