A quote from the Water Management section
The LCA depressurisation water is currently going to existing evaporation ponds. Are these evaporation ponds only temporary and enabling the depressurisation of the LCA or are they permanent and a part of the total evaporation pond requirement?
Are the additional three evaporation ponds required for the LCA to be depressurised and the decline to resume? Are they similar in size, smaller or larger than those currently being used?
After depressurisation will there be an ongoing flow of water to be pumped from the LCA and evaporated at surface for the lifetime of the mine? Is this flow expected to be greater than the amount of water being evaporated from the existing ponds?
Are the existing ponds able to cope with the amount of depressurisation water coming to surface or is depressurisation a stop start process which depends on evaporation rates?
A quote from the Water Management section
Summarised: Three more evaporation ponds required. Design submitted to WA EPA. Awaiting approval.Pleasingly, the potentially greater volumes of water that were anticipated inO ctober 2023 have
not eventuated, meaning that the project will continue with the surface water infrastructure
design as submitted in the WA Environmental Protection Authority (EPA) referral, which is for a
further three evaporation ponds that are constructed and utilised in a staged manner.
Opportunities to bring forward approvals for the final three evaporation ponds are being
progressed, and lining materials for two evaporation ponds have already been procured.
