Impact Minerals (ASX:IPT) Lake Hope Project: A high-purity pivot with environmental focus

In the heart of Western Australia, Impact Minerals (ASX:IPT) is spearheading an ambitious endeavour to meet the soaring demand for high-purity alumina (HPA), a critical material for technologies such as electric vehicle batteries and LED lighting.

The Lake Hope project, located 500 kilometres east of Perth, isn’t just another resource development; it’s a bold statement about how mining can harmonise profitability with environmental stewardship.

With a maiden measured resource announced and plans to deliver some of the purest alumina globally, Lake Hope is shaping up to be a standout project in the race to supply critical materials to sustainable industries.

Highlights:

• Maiden Resource: Lake Hope hosts 730,000 tonnes of measured resource at 25.8% alumina (Al₂O₃), equating to 189,000 tonnes of alumina.
• Global Scale: Positioned to deliver 4N HPA (99.99% purity) to a booming global market at over USD $20,000 per tonne.
• Sustainability at Core: Minimal environmental impact, with a “zero-liquid discharge” design and low carbon footprint.

Impact Minerals is carving a niche in the burgeoning high-purity alumina (HPA) market, and its Lake Hope Project in Western Australia epitomises the marriage of profitability and environmental stewardship.

With a measured resource estimated to sustain at least 15 years of production, the company’s Pre-Feasibility Study (PFS), due in early 2025, holds significant promise.

According to the company’s Managing Director, Dr Mike Jones, the project is designed with a forward-thinking approach. “The Lake Hope project represents one of the lowest carbon-intensive HPA production methods globally, aligning with the growing demand for sustainable critical materials,” he stated.

Transformational Potential

Lake Hope’s measured resources are part of a larger deposit totalling 2.78 million tonnes, indicating potential for extended mine life beyond 25 years.

The project’s robust economics include an after-tax net present value of AUD $1.3 billion, positioning it among the industry’s most cost-efficient HPA ventures.

The resource, hosted in fine-grained clays of dry salt lakes, will not require onsite beneficiation. Instead, raw material will be transported to Kwinana, where innovative low-temperature leaching and purification processes will transform it into HPA.

The proposed operations also minimise environmental disruption—a rarity in mining.

Technological Edge

Impact is capitalising on its partnership with Edith Cowan University’s Mineral Recovery Research Centre.

The collaboration employs Membrane Selective Technology (MST), traditionally used in water treatment, to revolutionise reagent recovery in mining.

This adaptation not only reduces operational costs but also underpins the project’s environmental credibility.

Dr Amir Razmjou of Edith Cowan University noted, “MST is a game-changer for Lake Hope, enabling cost-effective and sustainable HPA production by eliminating process waste”.

Federal Backing and Acceleration

A $2.87 million Cooperative Research Centres Projects (CRC-P) grant is accelerating Impact’s timeline.

The funding supports pilot plant construction and qualification trials for offtake agreements, with the initial disbursement arriving ahead of schedule in November 2024.

Beyond Traditional Markets

Demand for HPA is surging, driven by its critical applications in EV batteries, LED lighting, and semiconductors.

Lake Hope’s strategic focus on sustainability further strengthens its appeal to downstream users prioritising ESG compliance.

Far from being just another HPA project, Lake Hope sets a benchmark for responsible mining in a resource-hungry world.

As the Pre-Feasibility Study unfolds, Impact Minerals has the potential to redefine Australia’s position in the competitive critical minerals sector.
