Cobalt Blue Holdings Ltd (ASX:COB) has received a further boost for its Thackaringa Cobalt Project with the commissioning of a 270-kilometre water supply pipeline from the Murray River at Wentworth to Broken Hill.
The pipeline will help ensure the supply of up to 1.5 gigalitres per year of water by provider Essential Water to service the cobalt processing and refining requirements of the project.
Long-term water security
Cobalt Blue has extended its congratulations to WaterNSW and their project partners John Holland and MPC Group for the successful construction and commissioning of the pipeline.
This project will provide long-term water security for the community by supplying up to 37.4 megalitres per day to the Essential Water treatment plant at Broken Hill.
The company said that it would also significantly de-risk the Thackaringa Cobalt Project, which is about 25 kilometres southwest of Broken Hill.
Cobalt Blue continues to receive positive results from technical work at the project which is aimed at improving the positive outcomes from a pre-feasibility study (PFS).
Last week, positive results were received from large scale metallurgical test work with cobalt-pyrite concentrates produced from 45 tonnes of ore samples.
The weighted average recovery of cobalt from the ore to cleaner gravity concentrate was 68%, from a weighted average head ore grade of 1,002ppm while concentrate cobalt grade averaged 4,655ppm and the mass recovery was 14.5%.
Results add confidence that the target mass recovery to concentrate is about 20% and a target cobalt recovery from ore to concentrate of more than 90%.
The results will be used to optimise the process engineering design criteria and the produced concentrate will be used for thermal decomposition trials.
