Exploration Updates During 1H 2021, the Company continued to intensify its exploration activities, both in the Eastern and Western Corridor, in order to accelerate the finding of new Mineral Resources and Ore Reserves. Toka Tindung Gold Mine's deposits are classified as low sulphidation epithermal gold and silver deposits, with more "free" or native gold and better gold recovery rates compared to other types of deposits. During 1H 2021, Archi predominately mined Toka Pit (a large tonnage lower grade deposit) and the Kopra Pit (medium grade). In addition, completed mining of remaining tonnage in the high grade Araren stage 3 Pit, whilst developing a new mining area at the Alaskar Pit. 1 In Araren stage 5 Pit requires 5 months of waste mining prior to accessing high grade gold. This pre-stripping commenced in March and will be completed by August 2021. Araren stage 5 high grade gold will be the major source of ore to be processed in 2H 2021. Excitement came with the continuing success from the exploration drilling in the Bima gold deposit at Western Corridor, which is located approximately 15km west of the Toka Pit. Five diamond drill rigs have been in operation there since September 2020 and at the time of this announcement, they have completed 80 diamond drill holes amounting to 22,800 metres. These drillings have returned 33 intersections above a nominal cut-off of 20 gram metres, which represents a nominal minimum width of 4 metres at grade of 5 g/t gold. ☐ As of December 2020, the deposit in Western Corridor contained an Indicated and Inferred Mineral Resource of 2.2 Mt at 7 g/t of gold, for a potential of 493 koz of gold produced. These latest results, and additional drilling underway, are expected to significantly increase the Mineral Resources for 2021.
