text: For the 12 months to June 2013, the availability 
  of the RH90 fleet has been at 80%, with the 
  RH40 fleet at 78%. The target availabilities for 
  these fleets are 88% and 85% respectively. 
  Availability of the haul trucks was 85% versus a 
  target of 90% for the 777D fleet. A commit- 
  ment has been undertaken by the contractor to 
  address the under performance. 
  
  Approximately 2.5 days of production were lost 
  due to rainfall during the year. Total rainfall for 
  the year was 1.3 metres which is in line with the 
  long term average. 
  
  Mining operations continued on a 24 hour per 
  day basis throughout the year, with the excep- 
  tion of the development of Q prospect. 
  
  Due to the proximity of Q prospect to the 
  community and the local roads, development 
  began in March 2013 on a 5 day week basis 
  on day shift only. In April this was extended 
  to 7 days per week on day shift only.
