  8. Summarize % of ADDCAR Jim Bridger Year Tons (000) Plant Burn 2003 490 6 2004 1,011 12 2005 2,058 25 2006 (Est) 2,800 34 • Review ideas • Vote on top candidates and consolidate • Check requirements and restrictions • Trim list to top 5-10 ideas

  9. Mine Planning • Long term analysis is essential • Synchronization of equipment • Synchronization of qualities/ markets • Keeping available wall

  10. Mine Planning • Seam Height (ft): 2.5 – 30 • Hole Depth (ft): Typical 1,200 Max 1,600 • Monthly Output: Typical 125,000 Max 250,000

  11. Future Trends • Safety – NO Finish Line • Operations – Trench Mining Honey Comb Mine Plan • Reserves – Colorado: the most compliance bituminous coal • Markets – BTU matters • Technology – Steep dip, narrow bench, thin seam

  12. Medium Term Market Impacts of Highwall Coal State Tons / Yr (000) Western Wyoming 6,000 Southern PRB 4,000 Montana 2,400 Colorado 1,800 New Mexico 2,200 Total 16,400

  13. Conclusions • Highwall Mining in the West: • Reliable Supply • Cost Effective • Organic Expansion • Gaining Momentum • Who Would Have Thought ?
