Cautionary Note: The Company cautions that the estimated quantities of coal and carbonaceous shale disclosed in this press release represent an estimate of the potential of the noted permit areas based strictly on a review of technical data that is publicly available and are not intended to be construed in any manner as an estimate of any classification of reserves. Further appraisal is required before any estimated classification of reserves can be compiled. The Company’s upcoming appraisal drilling campaign is being undertaken in order to build the necessary data to be able to compile an estimate of reserves and make a later determination as to whether any noted reserves can be produced economically. There is risk that our upcoming appraisal drilling campaign will not be able to confirm the Company’s findings from its review of publicly available technical data.
