Overburden Geochemistry Data (1982) including sulfur forms (organic, sulfate, pyritic, <br />and total). In addition, all of the coal samples will also be analyzed by the "short" <br />Proximate Analysis plus sulfur forms (organic, sulfate, pyritic, and total). <br />The three holes will be located within the Permit boundary as shown on the attached <br />Figure 1 and as described below: <br />• NHN11-1, Easting 1,113,757, Northing 608,910, Est. Surf. Elev. 5742, TD <br />approx. 75 ft. <br />• NHN11-2, Easting 1,113,241, Northing 607,779, Est. Surf. Elev. 5740, TD <br />approx. 95 ft. <br />• NHN11-3, Easting 1,114,439, Northing 607,790, Est. Surf. Elev. 5762, TD <br />approx. 91 ft. <br />The three (3) hole locations were determined through discussions with CDRMS (Mike <br />Boulay). Access to the hole locations will be by overland travel with no dirt work <br />involved <br />Each of the three holes will be drilled with air/mist using a truck mounted drill rig with a <br />2 or 3 man crew. The drilling/coring will be done utilizing a 15 ft. split tube core barrel, <br />recovering a 3 inch diameter core. A lithium based joint compound will be used on the <br />drill pipe joints. Each of the three holes will be continuously core drilled from a depth of <br />about 15 ft. to total depth which is about two ft. below the bottom of the LDx Seam. The <br />top 15 feet or so of the hole will be drilled with a tri-cone rock bit (5-1/8" or 5-5/8") to <br />allow the core barrel to be placed in the hole. Samples of the top 15 ft. of the hole will be <br />chip samples (drill cuttings of that interval). <br />The core and cuttings will be measured, marked, described and sample increments <br />selected. Maximum length of each individual sample will be four (4) ft. as per DRMS <br />specifications with the goal of sampling the various lithologies (sandstone, siltstone, <br />shale and coal) separately. The samples will be bagged in plastic (core sleeve for core <br />and bags for cuttings) with the hole number, sample number, and depth interval clearly <br />marked on each sample bag. These sample numbers are to be used by the lab to identify <br />the samples on the report(s) of analyses. Following the analyses of the individual sample <br />increments, it is anticipated that the increments will be composited mathematically by <br />footage weighting into zones representing: 1) the overburden weathered zone; 2) the <br />overburden unweathered zone; 3) the UD1 coal seam; 4) the interburden between the <br />UD1 and LDx; and 5) the LDx coal seam. <br />After each of the holes has been core drilled to total depth, bentonite gel will be pumped <br />down the drill pipe and back to the surface and then each of the holes will be logged with <br />geophysical tool(s) (natural gamma ray, close spaced density, caliper and conductivity). <br />Following logging, each hole will be plugged by pouring two 50 lb. bags of 3/8" <br />bentonite chips down the hole. Drill cuttings or additional bentonite chips will be used to <br />fill the remainder of the hole to within 10 ft. of the surface. The top 10 ft. of the hole will <br />be filled with concrete and a survey marker with the hole number will be set in the top of <br />2
