text: Chatree gold production was 10% higher than 
  the previous corresponding period as a result of 
  an increase in throughput from the expanded 
  Chatree process plant and access to higher 
  grade oxide ore from Q Prospect. 
  
  Challenger gold production was 24% lower than 
  the previous corresponding year given additional 
  dilution and depletion at Challenger Deeps and a 
  shortfall in planned development. This resulted 
  in lower ore tonnes from the mine that was 
  supplemented by low grade stockpiled ore. 
  Following the fall in the gold price a strategic 
  review of Challenger was implemented that has 
  resulted in a new mine plan to focus primarily on 
  the higher grade Challenger West orebody. The 
  new mine plan will be implemented during the 
  first three months of the 2014 financial year. 
  
  A lower gold price and industry wide cost pres- 
  sures had a negative impact on the underlying 
  earnings of the Group which contributed to a 
  major impairment to the carrying value of a 
  number of Group assets, particularly assets 
  relating to the Challenger Gold Operations. 
  Impairments totalling $332,808,000 were the 
  major contributor to the after tax loss of 
  $323,726,000 for the year.
