Awak Mas Gold Project CIL/CIP Plant Detailed Design

The Awak Mas Gold Project is expected to be a low cost, long life gold mine (excess ten years) producing around 100,000 oz per year.

PT Petrosea are managing the global project engineering for MDA and have engaged Como Engineers to provide the detailed engineering design and execution, procurement support and commissioning planning and support for the mineral processing facility (Petrosea will undertake the procurement and construction).

Stage 1 of the processing plant is designed to process 2.5 Mtpa of gold ore via a SAG and Ball Mill grinding circuit including gravity gold recovery and CIL recovery of gold from gravity tailings. Gold will be recovered from the activated carbon using a 7 tonne capacity split AARL elution circuit and carbon regeneration plant.

Dore will be recovered by smelting of electrowon gold recovered from the CIL and gravity circuits. CIL tailings will be treated for safe disposal prior to pumping to a tailings storage facility 300 m below and 4.7 km distant from the process plant.

The Stage 1 design includes the provision for an expansion (Stage 2) for processing of 3.6 Mtpa in future.
