Feasibility study

DMS has completed the technical aspects of the optimisation of the feasibility study as previously announced and work continues on the capital aspects of the optimisation. Initial indications are that improvements from the updated technical aspects and the use of Chinese equipment will be positive. An updated feasibility study is anticipated to be completed and announced within the next 3 months.

Water

As previously announced, to support the local environment, as DMS had a quantity of carryover water surplus to requirements DMS traded 5 gigalitres (5,000 megalitres) of water to the Victorian Environmental Water Holder to help protect habitat, water quality and animals in Wimmera and Glenelg waterways and the western rivers. DMS was able to contribute to this important environmental cause (at well below DMS’s cost) having considered possible impacts of foreseeable future water allocations and DMS’s future project commencement needs.
