Resources & Reserves :
Exploration activity in 2013 and 2014 enabled a further JORC Resources report to be issued on 9 June 2015. MCM coal resources are now estimated at a total of 14.0 million tonnes (Mt), ofwhich 1.6 Mt is categorised as Measured, 8.3 Mt is categorised as Indicated with the balance of 4.1 Mt as Inferred. See announcement on 9 June 2015 for detail.
Coal haulage from MCM mining locations to jetty ≈ 20 – 30 Km.
Barging along Mahakam River to the Balikpapan Coal Terminal (approx. 640km).A new haul road and downstream deep water port are planned to overcome river and barging restrictions.
Production was commenced in 2012, but suspended due to low river levels in 2013. Additional exploration has been carried out and additional forestry permits (IPPKH) are being processed to enable exploration to commence in the other 3 concession areas.
PT. Mamahak Coal Mining holds a coal mining concession covering 4,996 hectares in West Kutai Regency, East Kalimantan Province. Mining in this concession commenced in January 2010 and continued until November 2012.
A decision was taken in late 2012 to close the MCM coal mine as it was no longer economic due to it being a high cost operation coupled with the continued decline of the Newcastle coal index and the river water levels only allowed barging for part of the year. Recommencement of mining in the future would be dependent on the identification of additional mineable coal reserves, establishment of a more accessible port location and a significant improvement in coal markets.
