At Broadmeadow East, the only economic seams occur in the Rangal Coal Measures which overlie the Fort Cooper Coal Measures. The Rangal Coal Measures are approximately 90m thick and contain five seams in descending order: the Burton Rider seam, the Leichhardt seam, the Upper Vermont seam, the Middle Vermont seam and the Lower Vermont seam. Only the Leichhardt seam is currently determined to be commercially viable in the Broadmeadow East area. The seams all crop in an elongated strip, broadly striking north northwest. The Rangal Coal Measures comprise interbedded fine to medium grained lithic sandstone, siltstone, mudstone and coal.The Project area lies within the Permo-Triassic Bowen Basin. Coal seams occur within the Rangal Coal Measures and underlying Fort Cooper Coal Measures which are Late Permian in age. Coal seams in the Broadmeadow East deposit dip to the North-West, West at approximately 8 - 10 degrees. The target seam is the Leichhardt seam in the Rangal Coal Measures, which are extensively mined in the area. The drill hole density (core and chip) in the deposit allow for a good level of confidence in seam splitting, seam thickness, coal quality and location of sub-crop lines.The Broadmeadow East ML deposit area occurs within a structurally complex zone on the eastern side of the Collinsville Shelf in the north Bowen Basin. The deposit is located on the eastern upthrown side of the Burton Range Fault, a regional scale meridional midTriassic thrust fault which lies to the west of the Broadmeadow mining leases and trends in a north-northwesterly direction.The economic coal seams in the north Bowen Basin lie within the Permian Blackwater and Back Creek Group. The Blackwater Group comprises two late Permian coal-bearing sequences; the Fort Cooper Coal Measures and the Rangal Coal Measures, while the Back Creek Group contains the Moranbah Coal Measures. The economic Burton Coal Project deposits occur within the Rangal Coal Measures.The Rangal Coal Measures contain the only economic coal seams in the Broadmeadow East ML area of which only the Leichhardt seam (BL), with an average thickness of between 3.5 and 4.2m is considered potentially commercial.The coal resources are in the west limited by the subcrop, otherwise resources exist over the entire ML70257. The strike length is approximately 2,800m.Depth of the BL seam at the subcrop is approximately 20m (Base of Weathering) and increases to approximately 300m in the north-east of the ML.
