Impact (ASX:IPT) quicksteps to milestone Lake Hope HPA study by year’s end

Impact (ASX:IPT) quicksteps to milestone Lake Hope HPA study by year’s end

July 10, 2024 Off By Amanda Ellis

Impact Minerals is set to produce its pre-feasibility study for its Lake Hope High-purity Alumina Project in Western Australia east of Perth in the December quarter of 2024.

The company is pursuing a three-pillared approach to the study, focusing on the mine, process plant, and sales.

Its sales pillar for the ground 550 kilometres from Perth, past Forrestania, takes in product development, marketing and offtake.

Impact Minerals Managing Director Dr Mike Jones compared the PFS to a puzzle the company was solving.

“The Lake Hope Pre-Feasibility Study is like a large jigsaw puzzle where we know what the final picture looks like and are now starting to see many of the individual pieces falling into place at a great pace,” he said.

“We have been focused on the puzzle’s edges with progress made at the proposed mine at Lake Hope itself, the process plant, which will be in Kwinana and, increasingly, product offtake and marketing.”

Kwinana is an industrial hub south of Perth on the road to Rockingham, navyship hub Safety Bay and Mandurah. It is an established centre for alumina that hosts the Alcoa Kwinana Alumina Refinery and other industries such as energy and petroleum.

“We have selected Kwinana as the site for the processing plant and our proprietary low-temperature leach as the best method to scale up HPA production to the planned 10,000 tonnes per annum because of substantial strategic advantages,” Dr Jones said.

“These include ready providers for all the reagents we need, ready buyers for our by-products and a site possibly suitable for the plant.”

CPC Engineering is on board to provide design engineering advice, and model capital and operating costs for an LTL process plant on the site.

The company is progressing well with its test work, recently identifying a product that could be used in industry and is assembling a marketing team as it hopes to crack the puzzle on how to fast-track plant development.


Following the production of its scoping study, Impact produced high-purity alumina exceeding 99.99 per cent at Lake Hope using a Playa One sulphate process.

Impact can take a stake of up to 80% in Lake Hope with its PFS.

The company’s environmental studywork has shown there is no threatened or priority species on the Playa site.

Lake Hope is on Ngadju Aboriginal group land and Impact is in negotiations with the community to build a mine on its country.

Impact’s positive scoping study for the project modelled a benchmark 10,000 tonnes a year HPA production level, featuring an estimated post-tax net present value (NPV8) of about A$1.3 billion.

At its modelled costing, the project could be one of the lowest cost producers of HPA in the world by a notable margin.

Impact hopes to complete its PFS by year’s end to position itself to make significant steps towards production next year.
