F <br /><~ , <br />,.~' the 2 West area of the Eagle No. 5 mine is both depositionally <br />and structurally different than the majority of the property. <br />In the 2 West area the F seam is underlain by shale and <br />sandy shale (siltstone) approximately 31 feet thick, and <br />sandstone which ranges in thickness from 5 to 30 feet. The <br />E seam underlies these units. The F seam is overlain by 18 <br />to 28 feet of shale, sandy shale, and thin coals capped by a <br />locally thick seam herein named the "G" seam. The G to F <br />interburden decreases to the east and north of the 2 S4est <br />area and the G seam merges with the F, most notably in the <br />area near the SA portals. ?he G seam is then overlain by 0 1 <br />to 6 feet of shale and 11 ~o~~~°'~E~~' o"f""s'~nc~sfone~ <br />Structurally, the 2 West area is near the axis of the Williams <br />Fork Anticline. This structure is slightly recumbent, with <br />the axial plane dipping to the northeast and plunging to the <br />north-northwest. The western limb becomes steeply dipping <br />and Empire Energy intends to continue mining until the dip <br />becomes prohibitive. <br />Sources of Data <br />The 2 West area has been carefully studied by rotary drilling, <br />spot coring, field mapping, photogrametric observation and <br />remote sensing techniques. Additional coring from within <br />the No. 5 mine is currently under~,aay. To date, coring <br />underground in 2 West has been achieved at two locations. <br />Please refer to Exhibit C for the locations of these holes. <br />Un~er~cround Drilling <br />The first hole drilled underground in 2 West was located ir. <br />2 West 1 R Entry at crosscut 54. This hole was designed to <br />provide a known control point with which otl;er holes could <br />be compared to determine seam correlation. This hole, <br />designated UG-8, showed the E seam to be 59.1 feet belcw the <br />F seam, and the G seam to be 24.3 feet abcve the F seam. <br />The results of the second hole (UG-9) indicate that the <br />first fault is a normal fault with displacement dowmaard to <br />the west. The down£aulted block has a slightly different <br />pitch than the eastern block, resulting in a scissor-like <br />displacement along the fault zone. Audi"tionally, core ;t <br />retrieved from the hole indicates that the displacement is <br />~', on the alder of 30 feet in. the area of 2 West Drains which <br />resul_ ~~+ ~~rau~ the F seam into the stratigraphically_ <br />` high"eY~ seam wfien the EatYrt was crossed.,;„A cross section <br />has been constructed utilizing holes L'G-8, tiG-9, TR-9, and <br />TR-10 (Exhibit B).
