SEDAR

Halifax, Nova Scotia June 30, 2021 - Namibia Critical Metals Inc. ("Namibia Critical Metals" or the "Company" or "NMI") (TSXV:NMI) 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 Oil, Gas and Metals National Corporation ("JOGMEC"). The Company also announces that it has received a renewal of the Environmental Clearance Certificate (ECC) for Mining Activities in Mining License (ML) 200 for the Lofdal Heavy Rare Earth Project. The ECC was issued by the Ministry of Environment, Forestry and Tourism Department of Namibia as an effective date of May 11, 2021, and is valid until May 11, 2024.

The terms of the JOGMEC JV Agreement stipulate that JOGMEC provides $3,000,000 in Term 1 and $7,000,000 in Term 2 to earn a 40% interest in the Lofdal project. Term 3 calls for a further $10,000,000 of expenditures to earn an additional 10% interest. The JV Agreement is structured such that no NMI equity will be issued and it is totally non-dilutive to NMI shareholders.

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.

Darrin Campbell, President of Namibia Critical Metals stated "We are incredibly pleased to have achieved this significant value inflection point of Lofdal with this impressive mineral resource upgrade. Increasing our Measured and Indicated mineral resource tonnage by over 1400% and over a 6 fold increase in contained dysprosium and terbium oxide from our 2012 maiden resource is an amazing accomplishment by our technical team. In addition, the receipt of the renewal of the Environmental Clearance Certificate for Lofdal is great news and is expected to be the last requirement for official issuance of the Mining License 200 for Lofdal. This is a very special situation with the potential to develop a sustainable source of heavy rare earths outside of China in a favourable and stable mining jurisdiction in Namibia."

Mineral Resource Estimate

As previously reported (May 20, 2021) the in-situ 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 undertaken by Namibia Critical Metals from 2010 to 2012, 2015 and more recently in 2020. From the assumed parameters a 0.1% TREO cut-off grade was calculated, which together with the Whittle optimised pit shell demonstrates reasonable prospects for eventual economic extraction (RPEEE) for the Mineral Resource. The Mineral Resource is classified into the Measured, Indicated and Inferred categories and is reported at a cut-off grade of 0.1% TREO (TREO refers to Total Rare Earth Oxides including Y2O3). The independent resource for Area 4 and for Area 2B was estimated by MSA as follows:

Table 1: Area 4 Mineral Resources Estimate for 0.1% TREO cut-off

Notes (also apply to Table 2):

1. All tabulated data have been rounded and as a result minor computational errors may occur.
2. Mineral Resources, which are not Mineral Reserves, have no demonstrated economic viability.
3. Quantities reported are the total quantities for the project regardless of ownership.
4. *TREO = Total Rare Earth Oxides and includes Y2O3
5. **HREO = Heavy Rare Earth Oxides and includes Y2O3
6. ***LREO = Light Rare Earth Oxides
7. Mt = Million tonnes, kt = Thousand tonnes.

The Term 1 objective of the joint venture to double the mineral resource was far exceeded as reported in the Company news release dated May 20, 2021 and highlighted in Table 3. Measured and indicated resources increased from 2.88 Mt @ 0.32% TREO to 44.76 Mt @ 0.17% TREO and inferred resources increased from 3.28 Mt @ 0.27% TREO to 8.67 Mt @ 0.17% TREO. Most significantly, the contained tonnages of the high value heavy rare earths dysprosium and terbium increased 6.1 times and 6.7 times, respectively (Table 4).

About Namibia Critical Metals Inc.

Namibia Critical Metals Inc. holds a diversified portfolio of exploration and advanced stage projects in Namibia focused on the development of sustainable and ethical sources of metals for the battery, electric vehicle and associated industries. The two advanced stage projects in the portfolio are Lofdal and Epembe. The Company also holds significant land positions in areas favourable for gold and base metal mineralization.

Heavy Rare Earths: The Lofdal Heavy Rare Earth Project is the Company's most advanced project having completed a Preliminary Economic Assessment in 2014 and full Environmental Clearance for a first mining area in 2016. The Company has received Notice of Preparedness to Grant the Application for a Mining Licence for Lofdal from the Ministry of Mines and Energy. The Company has lodged its acceptance of the mining licence and awaits finalization of the process from the Ministry. The project is developed in joint venture with Japan Oil, Gas and Metals National Corporation ("JOGMEC") who are funding the current CD$10,000,000 drilling and metallurgical program with the objective of doubling the resource size and optimization of the process flow sheet.

Gold: The Company's Exclusive Prospecting Licenses ("EPLs") prospective for gold are located in the Central Namibian Gold Belt which hosts a number of significant orogenic gold deposits including the Navachab Gold Mine, the Otjikoto Gold Mine and more recently the discovery of the Twin Hills deposit. At the Erongo Gold Project, stratigraphic equivalents to the meta- sediments hosting the recent Osino gold discovery at Twin Hills have been identified and soil surveys are progressing over this highly prospective area. The Grootfontein Base Metal

and Gold Project has potential for magmatic copper-nickel mineralization, Mississippi Valley- type zinc-lead-vanadium mineralization and Otjikoto-style gold mineralization. Detailed interpretation of geophysical data and regional geochemical soil sampling have identified first gold targets.

Tantalum-Niobium:The Epembe Tantalum-Niobium-Uranium Project is at an advanced stage with a well-defined,10 km long carbonatite dyke that has been delineated by detailed mapping and radiometric surveys with over 11,000 meters of drilling. Preliminary mineralogical and metallurgical studies including sorting tests (XRT), indicate the potential for significant physical upgrading. Further work will be undertaken to advance the project to a preliminary economic assessment stage.

Copper-Cobalt:The Kunene Copper-Cobalt Project comprises a very large area of favorable stratigraphy along strike of the Opuwo cobalt-copper-zincdeposit. Secondary copper mineralization over a wide area points to preliminary evidence of a regional-scalehydrothermal system. Exploration targets on EPLs held in the Kunene project comprise direct extensions of the cobalt-coppermineralization to the west, sediment-hostedcopper, orogenic copper, and stratabound manganese and zinc-leadmineralization.
