Files NI 43-101 Mineral Resource Estimate Report for the

Lofdal Heavy Rare Earth Project on SEDAR

Halifax, Nova Scotia May 21, 2024 - Namibia Critical Metals Inc. ("Namibia Critical Metals" or the "Company" or "NMI") (TSXV:NMI OTCQB: NMREF) is pleased to announce that the updated NI 43-101 Mineral Resource Estimate on the Lofdal Heavy Rare Earth Project in northern Namibia ("Lofdal" or "the project") has been filed on SEDAR. Lofdal is a joint venture between the Company and Japan Organization for Metals and Energy Security ("JOGMEC").

Lofdal is unique as one of only two primary xenotime projects under development in the world. The deposit has the potential for significant production of dysprosium and terbium, the two most valuable heavy rare earths used in high powered magnets. The joint venture with JOGMEC is driven by Lofdal's potential to be a long term, sustainable supply of heavy rare earths for Japan.

Mineral Resource Estimate

As previously reported (Press Release of April 9, 2024) the updated Mineral Resource Estimate was independently prepared by The MSA Group of South Africa ("MSA") and was based on geochemical analyses and density measurements of core samples obtained by diamond drilling and drill chips obtained by reverse circulation drilling undertaken by Namibia Critical Metals from 2010 to 2012, 2015, 2020 and more recently in 2023. From the assumed parameters a 0.1% TREO cut-off grade was calculated, which together with the Whittle optimized pit shell demonstrates reasonable prospects for eventual economic extraction (RPEEE) for the Mineral Resource.

The Mineral Resource is reported as Measured, Indicated and Inferred Mineral Resources as shown in Table 1 for Area 4 and Table 2 for Area 2B. The Mineral Resource was estimated using The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Best Practice Guidelines (2019) and is reported in accordance with the 2014 CIM Definition Standards, which have been incorporated by reference into National Instrument 43-101 - Standards of Disclosure for Mineral Projects (NI 43-101).

The Qualified Person (QP) for the Mineral Resource estimate is Mr. Jeremy C. Witley (BSc Hons, MSc (Eng.)). In the QP's opinion, the Mineral Resources reported herein at the selected cut-off grade have "reasonable prospects for eventual economic extraction", taking into consideration mining and processing assumptions. The Mineral Resource was reported from within a Whittle optimised pit shell at a cut-off grade of 0.10% TREO.

The Area 4 Mineral Resource Estimate has increased from the previous estimate of 12 May 2021 (see Tables 3 and 4), due to the additional drilling, which has expanded the Indicated and Inferred Mineral Resources, along with changes in the economic input parameters used to define the optimised pit-shell for determining Reasonable Prospects for Eventual Economic Extraction (RPEEE). The Inferred Mineral Resources have increased in tonnages due to the additional RC drilling which has extended the Mineral Resource in a northeasterly direction along strike.

About Namibia Critical Metals Inc.

NMI is developing the Tier-1 Heavy Rare Earth Project, Lofdal, a globally significant deposit of the heavy rare earth metals dysprosium and terbium. Demand for these critical metals used in permanent magnets for electric vehicles, wind turbines and other electronics is driven by innovations linked to energy and technology transformations. The geopolitical risks associated with sourcing many of these metals has become a repeated concern for manufacturers and end users. Namibia is a proven and stable mining jurisdiction.

The Lofdal Project is fully permitted with a 25-year Mining License and is under a Joint Venture Agreement with Japan Organization for Metals and Energy Security (JOGMEC).

The Company filed a robust updated PEA for "Lofdal 2B-4" on November 14, 2022, with a post-tax NPV of USD$391 million and an annual IRR of 28% with a capital expenditure of USD$207 million. The project is projected to generate a life of mine nominal cash flow of USD$698 million post-tax over a 16-year mine life.

About Japan Organization for Metals and Energy Security (JOGMEC) and the JV

JOGMEC is a Japanese government independent administrative agency which seeks to secure stable resource supplies for Japan. JOGMEC has a strong reputation as a long term, strategic partner in mineral projects globally. JOGMEC facilitates opportunities with Japanese private companies to secure supplies of natural resources for the benefit of the country's economic development.

Rare earth elements are of critical importance to Japanese industrial interests and JOGMEC has extensive experience with all aspects of the sector. JOGMEC provided Lynas with USD$250,000,000 in loans and equity in 2011 to ensure supplies of the Light Rare Earths metals suite to the Japanese industry.

Namibia Critical Metals owns a 95% interest in the Lofdal project with the remaining 5% held for the benefit of historically disadvantaged Namibians. The terms of the JOGMEC joint venture agreement with the Company stipulate that JOGMEC provides C$3,000,000 in Term 1 and C$7,000,000 in Term 2 to earn a 40% interest in the Lofdal project. Term 3 calls for a

5

further C$10,000,000 of expenditures to earn an additional 10% interest. JOGMEC can also purchase another 1% for C$5,000,000 and has first right of refusal to fully fund the project through to commercial production and to purchase all production at market prices. The collective interests of NCMI and historically disadvantaged Namibians cannot be diluted below a 26% carried working interest upon payment of C$5,000,000 to JOGMEC for the dilution protection. NMI may elect to participate up to a maximum of 44% by funding pro rata after the earn in period is completed.

To date, JOGMEC has completed Term 2 and earned a 40% interest by reaching the C$10 million expenditure requirement. Total approved project funding to date is C$14,541,000 of the $20,000,000 Earn-In requirement to reach 50% interest.
