ASSET OVERVIEW

The Mine

  • Commenced production in 2006 as a truck shovel operation
  • Dragline operations commenced in 2011/2012 
  • Historically targeted over 2 Mtpa of product coal
  • Placed on care and maintenance late 2014

Coal Handling and Preparation Plant (CHPP)

  • Coal trucked to the CHPP and washed to form a product at a total yield of 70-75%

Transport and Sales

  • Product coal is railed 172km to DBCT via the Gooneyella Rail System
  • Sold primarily to Japanese, Korean and Taiwanese steel makers


MINE LAYOUT - ISAAC PLAINS & ISAAC PLAINS EAST

  • Well laid out site with mine infrastructure located along western side of lease
  • Short spur connection to Goonyella Brach  Railway
  • Ease of access for potential Isaac Plains East extension via haul road
  • Close to camp accommodation facilities


ACQUIRED ASSETS

Product Split

    • Bucyrus BE1370
    • High performance machine. In last year of operation under previous ownership moved >15m bcm
    • Major pre-start service planned including replacement of swing rack

    Train load out


      • CHPP, stockpile and train loadout in close proximity
      • Conveyorfeed to rail surge / loading bin

      Coal Handling & Processing Plant

        • 500tph feed rate (3.5Mtpa) constructed in 2006
        • Belt press filter - no tailings dams
        • Flexible operating setup to produce multiple coal products

        Office facilities and workshops

        • Established office setup includes comms and other infrastructure
        • Several maintenance workshops


        GEOLOGY


        • The Leichhardt seam (Rangal Coal Measures)  averages 3.5m thick across the deposit. The seam splits into an upper and  lower section in the far northern area
        • Depth of cover commences at 60m, dipping to  the east of 6-7 degrees with a maximum depth around 230m in the north east  of the tenement
        • Nine year mining history provides significant information about the deposit
        • Isaac Plains – over 100 cored holes drilled in unmined portion of Mining Lease
        • Isaac Plains East – over 200 holes drilling within tenement area
        • Over 18 km of 2D seismic over combined  tenements


        COAL RESOURCES RESERVES


        • Xenith Consulting Pty Ltd updated the  Resource and Reserve estimate for Stanmore in 2017 within the Mining Lease area and the new Isaac Plains East area currently.
        • Significant Resource coverage within Mining Lease
        • Current Reserves support over 8 years of open cut mining at planned mining rate of 1.5Mtpa ROM

        COAL QUALITY

        •   Historically sold primarily to North Asian steel makers - attractive coal qualities may broaden customer base
        • Plan to continue to produce three products;         
          • Semi-Hard Coking Coal        
            • Moderate ash and volatile matter content
            • Low impurities such as sulphur and alkalis  
          • Semi-Soft Coking Coal                 
            • Attractive volatile matter content, lower than Hunter Valley benchmark        
            • Low total sulphur with high calorific value
          • Thermal
          • High energy content with low sulphur, ash and nitrogen content, excellent handling characteristics, easy to grind.
        • Approximately 70% of historic production was coking coal


        INFRASTRUCTURE POSITION


        • Approximately 1.1Mtpa of rail and port capacity
        • Further expansion capacity available in  current market environment
        • Total transport infrastructure costs under  A$15/tonne at steady-state production
        • Significant capacity within Isaac Plains  CHPP and train load out up to 2.8Mtpa of production

        ISAAC PLAINS EAST PROJECT

        • Ability to utilise 100% owned dragline once  Isaac Plains open cut mining is completed
        • Low cost coal – strip ratio starts at under 5:1
        • Significant potential synergies with Isaac Plains - minimal capital required to open up brownfield expansion (2km haul road and other minor infrastructure only)
        • Similar coal quality product expected based on historical results analysis
