MAKUUTU PHASE 4 DRILLING PROGRAM UPDATE
The Board of Ionic Rare Earths Limited (“IonicRE” or “The Company”) (ASX: IXR) is pleased to provide an update on the progress on the Phase 4 drilling program for its 51% owned Makuutu Rare Earths Project (“Makuutu” or “the Project”). Makuutu is one of the world’s largest scale ionic adsorption clay (“IAC”) hosted Rare Earth Element (“REE”) deposits, located 120 km east of Kampala in Uganda.
The Makuutu Mineral Resource Estimate (ASX: 3 March 2021) was announced at 315 Million tonnes at 650 ppm Total Rare Earth Oxide (TREO) with a cut-off grade of 200 parts per million (ppm) TREO minus Cerium Oxide (CeO2) (see Table 1).
IonicRE has initiated the Phase 4 drill program at Makuutu (ASX: 15 June 2021), with the second drill rig now mobilised, and to date completed 55 drill holes (687 metres). Additionally, the Company remains on track for the mobilisation of the third rig to site at the end of July in what will be the largest program initiated at Makuutu. The committed program at present stands at 5,700 metres of drilling.
The aim of the Phase 4 drill program is to covert the Inferred Resources on RL 1693 to Indicated and Measured Resource category, plus also converting RL 1693 Exploration Targets to classified resources. These higher classified resources will then be used to underpin the Makuutu Feasibility Study.
Phase 4 infill drilling has initially started near Makuutu Central Zone (MCZ) on RL 1693, specifically prioritising infill drilling to areas immediately adjacent to the existing Indicated Resource area, Central Zone East (CEZ) Inferred, CEZ Unclassified Exploration Target, Central Main Zone Inferred, plus areas F, G and H, as illustrated within Figure 1. The zones represent the highest identified Total Rare Earth Oxide (TREO) grade Inferred and Exploration Target mineralisation at Makuutu.
The drill program will focus initially on infill drilling on a 200m grid to support conversion from Inferred Resources to Indicated Resources. An allocation of drilling on a 100m grid will then be completed with a desire to confirm a portion of Measured Resources for the Feasibility Study.
The Company will provide updates to the market as progress continues with the advancement of the drill program.

About Makuutu Rare Earths Project
The Makuutu Rare Earths Project is an ionic adsorption clay (“IAC”) hosted Rare Earth Element (“REE”) deposit located 120 km east of Kampala in Uganda and is well serviced by existing high quality infrastructure including roads, rail, power infrastructure and cell communications. The installed infrastructure is illustrated in Figure 2.
The Company will move to 60% ownership of Makuutu on the completion of the Feasibility Study and has a pre-emptive right over the remaining 40% stake in the Project.

The deposit stretches 37 km in length and has demonstrated potential for a long life, low-cost capital source of critical and heavy rare earths. These IAC deposits are prevalent in southern China which have been the source of the world’s lowest cost critical and heavy REE production, however these deposits are gradually being exhausted and Makuutu represents one of only a handful of such deposits outside of southern China.
The Makuutu deposit is shallow, with less than 3 m of cover over a 9 m average thickness clay and saprolite zone which results in low-cost bulk mining methods with low strip ratio. A maximum thickness of 19.5 m has been identified at Makuutu. Processing is via simple acidified salt desorption heap leaching, breaking the chemical ionic bond which washes the rare earths (in a chemical form) from the ore into a pregnant leach solution (“PLS”). The PLS is concentrated up using membrane technology, from which the rare earths are precipitated as a mixed rare earth carbonate product; a product which attracts both a higher payability and achieves a high basket price due to the dominant high value critical and heavy rare earths which make up over 70% of the product basket.
The Project has the potential of generating a high margin product with an operation life exceeding 27 years. The Project is also prospective for a low-cost Scandium co-product.
Existing Infrastructure
One of the Makuutu Rare Earths Project’s competitive advantages is its proximity to existing infrastructure. The Makuutu site is approximately 10km from Highway 109 which is a sealed bitumen road connecting to Kampala, to Kenya and on to the Port of Mombasa. All weather access roads connecting the site to the adjacent sealed bitumen highway are already existing. A rail line lies within 10 kilometres north of the Makuutu site near the town of Iganga. There are four hydroelectric power plants located within 65 km of the project area, with total installed generating capacity of approximately 810 MW, providing an abundant supply of cheap power to the Project.
Water will be sourced at the project by harvesting water from the Makuutu site, given the Project location in a positive rainfall environment, and a net positive process water balance will require membrane processes to be used to process site discharge water for reagent recovery. Excess water management will be a key focus of the Project the ensure environmental standards are met and reagent consumption is minimised.
A workforce of semi-skilled and artisanal workers is available in nearby towns and population centres. The closest major population centre is Iganga, which has a population of 50,000. The town of Mayuge is approximately 10 km from the Project site and the intent is to source local operations staff from the immediate districts and train staff accordingly. The operation is to be staffed by a residential workforce. No fly in – fly out is envisaged, and the number of expatriate staff is intended to be low, and to be phased out over time. Industrial facilities are available in the city of Jinja, approximately 40 km from the Project area. Additional industrial facilities are available on the outskirts of Kampala.
