Linc <br />(AERGY <br />3.2 Drilling Program (Phase 2) cont. <br />Continuous and /or conventional coring operations will be needed to provide a core <br />diameter size suitable for the amount of material needed for geomechanical and analytical <br />testing. For continuous coring, either HQ (2.5 inch diameter core) or PQ (3.4 inch <br />diameter core) size core would be sufficient. For conventional coring a comparable core <br />diameter would suffice. Numerous types of analyses are required to characterize the <br />coal, therefore high core recovery of the coal seam is paramount. A double or triple tube <br />core barrel assembly is desirable for generation of the best geotechnical descriptions and <br />samples for geomechanical testing. <br />Holes drilled within the concession will require equipment to control potential gas. <br />Smoking will be banned within the perimeter of each drill site and welding will require gas <br />tests prior to and during the work. As a safety precaution, a gas tester will need be <br />present on each rig. Gas desorption and analytical testing of the gas is planned for the <br />target coal seams. <br />Pending hole conditions, geophysical wireline logging is planned for all exploration holes. <br />A standard coal suite of logs will be run down the entire length of the hole. The typical log <br />suite will likely include gamma, compensated density, caliper and resistivity. Sonic, high <br />resolution density and verticality logs may also be included. It may be necessary to log <br />the hole through the drill pipe therefore the wireline service contractor will need to plan for <br />an additional smaller diameter gamma tool for inner pipe clearance. <br />9 <br />
