Emerging critical minerals producer Cadoux (ASX:CCM) has completed a key engineering phase of the planned small scale and demonstration high-purity alumina (HPA) production facility.
Stage one development work is considered the pre-final investment decision (FID) activities, which included flowsheet development, optimising, and engineering. The second phase of this work includes front end engineering.
Concurrently, the company has also appointed GR Engineering Services as engineering contractor for the second phase of the engineering study.
Phase two engineering work streams will include updating the capex estimate, planning project execution, master document register, HAZOP reports, specifications and datasheets, as well as final plot plant, general arrangement, piping and instrumentation diagram drawings.
Cadoux, which has a market capitalisation of $20.77 million, says once completed, phase one and two work streams will combine to provide a higher level of engineering confidence than a Definitive Feasibility Study.
The studies are aimed at a front end engineering and design level to demonstrate to stakeholders that the project can be constructed and operated profitably while also meeting all relevant regulatory, environmental, and legal requirements.

Managing Director Roland Hill says GR Engineering Services is highly regarded for their hydrometallurgical experience and successful project completion track record.
“GRES will complement the HPA project delivery team exceptionally well as they were the lead engineering firm involved in the delivery of the original HPA Feasibility studies,” Hill says.
“We look forward to working closely with GRES over the next development stages and together add significant value to the HPA Project.”
Cadoux says it is focused on development of its critical minerals projects, including producing HPA in Western Australia, the Minhub mineral sands and rare earths processing facility in the Northern Territory and associated downstream development opportunities.
