The current methodology for delineating and subsequently evaluating coal reserves is based on the use of vertical drill holes and surface based geophysics/geology. These techniques have three major problems, these being respectively:- a) Vertical drill holes can only provide a small sample of the coal seam and stratigraphy. Therefore the planar variation in coal reserve and environment parameters can only be approximated._x000D_
b) Although surface based geophysics has had its fair share of success in recent years, there are still environments which have masked the finding of major structures._x000D_
c) Access to drill sites is difficult at some locations due to mountaineous terrain, standing water and environmental impact.
