Maiden Mineral Resource Estimate

13.6 million tons at 2.42% TREO

 

Altona (LSE: REE), a resource exploration and development company focused on Rare Earths in Africa, is pleased to announce its maiden JORC compliant Mineral Resource Estimate ("MRE") for its Monte Muambe rare earths project in Mozambique.

 

Key highlights: 

 

·    13.6 million tons at 2.42% TREO(1) using a cut-off grade of 1.5% TREO;

 

·    Including 0.31% NdPrO(2) representing 42,500 contained tons NdPrO;

 

·    58% of the reported tonnage in the Indicated category;

 

·    Mineralisation open at depth at both Target 1 and Target 4; and

 

·    The Scoping Study is expected to be finalised for publication no later than the third week of October.

                                                  

(1)   TREO (Total Rare Earth Oxide) is the sum of all Rare Earth Elements and Yttrium, expressed in percentage.

(2)   NdPrO is the sum of Nd2O3 and Pr6O11, expressed in percentage, and is included in TREO%.

 

The estimate, which is focused on the high-grade zones of the deposit, is in line with Altona's expectations and it follows the Company's strategy of focusing its endeavours on the part of the deposit that is most likely to be exploitable, as opposed to "drilling for numbers", in order to fast-track the project towards production.

 

The complete Competent Person Statement is available on the Company's website investor section: https://www.altonare.com/investors/reports/

 

The MRE represents an increase of tonnage compared to the high-grade part (2% TREO cut-off) of the Exploration Target estimate published on 8 August 2022.

 

Future resource increases will be achieved by drilling below the level of pit shells at Target 1 and 4, resource drilling at Target 3 and Target 9, as well as on-going exploration work.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The estimate includes 42,500 tons of contained Neodymium ("Nd") and Praseodymium ("Pr") Oxides. These elements are the most sought after "Magnet Metals" due to their usage in the manufacture of power drivetrains for electric vehicles ("EV") and wind turbines. They are therefore critical for the world's energy sources decarbonisation, and the future of the EV market relies just as heavily on sustainable sources of Nd and Pr as it does on battery minerals, such as lithium, graphite and cobalt.

 

The Company is now fully focused on finalising its updated Competent Person Report ("CPR") which will include all the details of the MRE computation, as well as the Scoping Study, which is expected to be published no later than the third week of October. The minor delay in the expected publication date of the CPR is due to additional work being required on the Scoping Study, part of the report to ensure the highest standard of document is produced.

The completion of the CPR will also trigger the increase of Altona's holding in Monte Muambe to 51% from its current position of 20%, and the start of Phase 3 of the farm-in agreement. 

Cedric Simonet, CEO of Altona, commented: "Monte Muambe's maiden MRE is an important milestone for us. This is the first ever official measure of the size and grade of the project and we are delighted with the results, which confirm the presence of a potentially open-pit mineable REE resource. The size is of the same order of magnitude as some of our published peers' ore reserve estimates and will be further increased through down dip drilling at both Target 1 and Target 4, as well as resource drilling at Target 3 and Target 9.

 

"The Company is now finalising its Scoping Study, which will give a first-pass economic viability overview of the project, to the highest standard."

The MRE does not correspond to the entire block model constructed from the drilling data, but to the part of the model for which the following reasonable prospects for eventual economic extraction ("RPEEE") were applied: pit shells based on a 1.5% TREO cut-off, revenue of 24.65 USD/kg TREO in Mixed Rare Earth Carbonate (MREC), and average total recovery to MREC of 48%.

Note: The words 'JORC Compliant' should be interpreted as 'Reported in accordance with the JORC Code and estimated (or based on documentation prepared) by a Competent Person as defined by the JORC Code', in accordance with the JORC Code 2012.
