Special Report: A significant bulk sampling and test pit program has been completed at Impact Minerals’ flagship Lake Hope high purity alumina (HPA) project, ticking off a key part of the PFS currently underway.

Impact Minerals (ASX:IPT) has made further progress with a PFS on its Lake Hope project in Western Australia with the completion of a bulk sampling and test pit program.

A total of 5.5t of material was collected from the 25 bulk samples taken from test pits across West and East Lake which host the 3.5Mt alumina deposit at Lake Hope.

In addition, earthworks for access tracks and drill pads for water bores for groundwater monitoring were also completed.

These latest developments come hot on the heels of a positive scoping study that indicated the project may be the lowest cost producer of HPA globally by a significant margin.


Primed for forthcoming stages of development

“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,” IPT managing director Dr Mike Jones says.

“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.

“These bulk samples will set us up for the forthcoming stages of development, which will include the commissioning of a mini-pilot plant once the initial test work is completed.”


PFS completion set for 2024

Jones says the company’s focus for 2024 will be to complete the PFS, which will include setting up the mini-pilot plant and, in particular, producing HPA in bulk for potential customers and off-take 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,” he says.

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