Notes:

  1. Mineral resources are reported inclusive of ore reserves, except Jabal Sayid copper mine. Jabal Sayid resource is reported exclusive of the reserve in accordance with Barrick Gold’s public reporting practice.
  2. Resources and reserve estimates are reported on a 100% basis irrespective of Ma’aden’s ownership percentage. Resources and reserves are 100% owned by Ma’aden except for Al Baitha (74.9%), Al Jalamid (70%), Al Khabra and B6 (60%), and Jabal Sayid (50%).
  3. Gold resources and reserves are reported as combined oxide and sulphide ore, which is not in line with JORC Code requirements for public reporting.
  4. Some mineral resources have not been converted into ore reserves as feasibility studies to estimate ore reserves have not yet commenced and /or are not yet completed as at the date of reporting.
