MONTE MUAMBE – PHASE 1 ASSAY RESULTS

SIGNIFICANT NdPr POTENTIAL

Altona (AQSE: ANR.PL), a mining exploration company focused on the evaluation, acquisition and development of Rare Earth Elements (“REE”) mining projects in Africa, is pleased to report the final Phase 1 assay results from Monte Muambe, its Light REE project in Mozambique.

SUMMARY

• Phase 1 assay results show significant REE levels across multiple target areas
• NdPr levels identified in significant levels
• Individual intercepts with up to 7.24% TREO and up to 1.21% NdPrOx;
• Out of the 6 targets drilled, 4 have significant REE mineralisation and warrant follow-up, 2 being new discoveries
• NdPr are the key metals used in the manufacture of permanent magnets for the drivetrains for Electric Vehicles and Wind Turbines

Monte Muambe is a 4km diameter circular carbonatite intrusion located in Tete Province, Northwest Mozambique, held under Prospecting Licence 7573L. The Company commenced an initial drilling programme in October 2021, focusing on six target areas, drilling a total meterage of 590m Diamond Drilling (DD - 5 holes) and 2,541m Reverse Circulation (RC - 38 holes).  The Company had 705 Diamond Drilling (”DD”) samples and 974 Reverse Circulation (“RC”) samples (including QAQC samples) assayed by Intertek in South Africa and Australia.

Significant Phase 1 intercepts are summarised below:

Table 1 – Significant Intercepts – RC holes

Table 2 – Significant Intercepts – DD holes

Note:

TREO% = sum of all rare earth oxide assay results including Yttrium

NdPrOx% = sum of Pr₆O₁₁ and Nd₂O₃ assay results

Phase 2 Programme

Phase 2 groundwork commenced in March 2022 and included additional soil sampling and ground geophysics to identify potential new targets. Drilling equipment is being mobilised at the start of May to perform scout drilling (1,200m RC) and resource drilling (6,800 RC), with a phase of metallurgical testing at the end of 2022; all of which will be used to produce a maiden Mineral Resource Estimate and a Preliminary Economic Assessment.

The current priority is to test the lateral extension of holes MM021 and MM042, and to continue drilling Target 1 in a south-easterly direction.

Christian Taylor-Wilkinson, Chief Executive of Altona, commented, “Our goal is to fill a significant gap in the global REE supply chain as demand for NdPr and the other critical metals continues to rise. This early success at Monte Muambe, together with our developing African infrastructure, increases Altona’s opportunity to become a serious partner to any of the major manufacturers which rely upon a sustainable supply of critical rare earth metals.”
