Danakali has said that preliminary materials, including a capital estimate and project schedule, for EPCM Phase 2 of its Colluli sulfate of potash project in Eritrea have been delivered by DRA Global (DRA).

DRA are providing contemporary information allowing advancement to the next phase of project development and identifies focus areas to manage the design and process risks during the detailed design phase. The Colluli Mining Share Co. (CMSC) project team are now in the process of reviewing the deliverables.

EPCM Phase 2 identified and commenced additional test work that was planned to be undertaken as part of the Phase 3 detailed engineering. CMSC took the opportunity with the Covid-19 travel restrictions to advance these test work items immediately. The output of this test work supports environmental and capital optimisation opportunities. Contracts have been awarded in support of this test work.

Within the Water Intake Treatment Area (WITA) a number of potential opportunities have been identified to improve environmental outcomes. The key opportunities are identified as the use of filtered sea water in the processing plant and using beach wells as the water intake alternative. A desktop study is underway to evaluate the beach well intake option. The use of filtered sea water in the process plant is being assessed as part of the additional test work that has commenced.
