September 2024 Quarterly Report

Impact Minerals Limited (ASX:IPT) is pleased to present its Quarterly Report.

HIGHLIGHTS

1. Lake Hope High Purity Alumina (HPA) Project, WA (IPT earning 80%)

• The Mine at Lake Hope:
  • A negotiation protocol for Land Access and Cultural Heritage agreements with the Ngadju peoples reviewed and signed.
  • Applications for a Mining Lease and associated Miscellaneous licence lodged.
  • Infill drilling to define a maiden Measured Resource and Proven Reserve completed with resource calculations and economic studies in progress.
  • Mining studies underway to provide mining schedules, proposed equipment, site logistics and costs of mining and transport of ore to Kwinana.
  • Further flora fauna and heritage surveys are being planned for the mine haul road.
• The Process Plant:
  • Kwinana selected as the location for process plant to produce a benchmark 10,000 tonnes per annum of HPA due to access to providers of the required input chemical reagents, buyers of the fertiliser and acid by-products and access to suitable land. Combined, these provide substantial strategic advantages for the project with savings on capex and opex.
  • The Low-Temperature Leach process selected as the most straightforward processing method to produce HPA at scale.
  • CPC Engineering selected to provide a design and engineering study for the full-scale plant that is underway.
• Product development, offtake and marketing
  • Further test work on HPA and fertiliser by-products continues.
  • Experimental work has produced a hydrated alumina product that may have major applications in the catalyst and flame retardant industries.
  • Early-stage discussions are underway for potential synergies with existing alumina businesses in Europe and the USA.
  • A marketing and product development team is being assembled.

2. Arkun-Beau, WA (IPT 100%)

• No major no activity occurred this quarter, though efforts remain on track to resume exploration after the cropping season ends in the wheatbelt in December.
• 413 soil samples were re-assayed to refine drill targets at Beau and Caligula prospects
• Land access agreements and statutory approvals are being finalised ahead of planned drill programme in Q1 2025
• Previous geochemical and MME survey data at Caligula support the project potential, with $180,000

PROJECT REPORTS

1. LAKE HOPE HIGH PURITY ALUMINA PROJECT, WA (IPT earning 80%)

Figure 1. Location of the Lake Hope Project and proposed haul route to Kwinana.

During the Quarter Impact Minerals announced that it had lodged a Mining Lease Application (MLA63/684) and associated Miscellaneous Licence (L63/99) for the Lake Hope High Purity Alumina (HPA) Project located 500 km east of Perth in Western Australia, (Figures 1 and 2). This is a crucial step in advancing the project towards production as it defines the work required to obtain the statutory approvals needed for the grant of the Mining Lease.

The approvals process, together with the logistics and estimated costs of mining and transporting the Lake Hope mud to the process plant, form one of the four key parts of a Pre-Feasibility Study (PFS) on Lake Hope, which is in progress (Figure 3 and ASX Release July 10th, 2024). Impact can take an 80% interest in Playa One Pty Limited, which owns the Lake Hope Project and associated intellectual property, by completing the PFS (ASX Releases March 21st 2023 and July 10th 2024).

The PFS followed on from a positive Scoping Study, which showed that for a benchmark production of 10,000 tonnes per annum of HPA, the Project has an estimated post-tax Net Present Value (NPV8) of about A$1.3 billion and would potentially be one of the lowest-cost producers of HPA globally (ASX Release November 9th 2023).
