Impact Minerals Bulk Sampling and Test Pit Program Completed at Lake Hope HPA Project



Impact Minerals (ASX: IPT) Announced that a significant bulk sampling and test pits program has recently been completed at their flagship Lake Hope High Purity Alumina (HPA) project located 500 km east of Perth in Western Australia.


The program is a critical component of the PreFeasibility Study on Lake Hope, which is currently underway following a positive Scoping Study on the project that indicated the project may be the lowestcost producer of HPA globally by a significant margin (ASX Release 9th November 2023).

Impact has the right to earn an 80% interest in the Lake Hope project by completing the Prefeasibility Study (ASX Release 21st March 2023).

A total of 5.5 tonnes of material was collected from twentyfive bulk samples taken from test pits across West Lake and East Lake, which host the alumina deposit at Lake Hope.


The deposit contains a resource of 3.5 million tonnes at 25.1% alumina (Al2O3) for a contained 880,000 tonnes of alumina, of which about 88%, or about 775,000 tonnes of alumina, is in the higher confidence Indicated Resource category (ASX Release 19th June 2023).



Managing Director Dr Mike Jones said:

This bulk sampling program marks another significant milestone in our journey towards the production of High Purity Alumina (HPA) from Lake Hope and caps off a very busy and successful nine months since acquiring the rights for this exceptional project.

“In that time, we have completed a maiden resource statement, obtained heritage clearance from the Ngadju First Nations people, completed most of the first phase of metallurgical test work using the unique Playa One sulphate process, and completed a Scoping Study.


“The results of that study were outstanding and demonstrated the potential of Lake Hope to produce HPA at a cost much less than any other supplier globally, and this has given us the confidence to progress the prefeasibility study aggressively.


“The bulk samples will set us up for the forthcoming stages of development, which will include the commissioning of a minipilot plant once the initial test work is completed.

Our focus for 2024 will be to complete the PFS, which will include setting up the minipilot plant and, in particular, producing HPA in bulk for potential customers and offtake partners.


“As part of this strategy, we have already started reaching out to key groups in the battery and LED market, and the demand is there.


“We look forward to a watershed year for Lake Hope, Impact and its shareholders”.

Impact confirms that no new information exists, and all modifying factors remain the same as at the time of the first publication of the resource.
