  • All 52 drillholes within the Millerton North resource block were drilled using wash drill methods
  • Seams show a trend of decreasing ash content through the middle of the coal seam with average ash increasing as seam thickness decreases. Average ash ranges from 3.3 – 53.4% for main Mangatini seam samples
  • Sulphur levels are variable within the main seam, with a trend of decreasing sulphur content in the lower section of the seam. Sulphur content ranges from 1.2 – 6.7%
  • Most seams have an average of 7 – 9 swell. Weathering has resulted in significantly reduced swell in the top and base 0.5 – 1m of seams in 10 of the drillholes
