GoviEx Announces Substantial Increase of Open-Pit Mineral Resources at Its 100% Owned Muntanga Uranium Project in Zambia

• Measured & Indicated resources nearly tripled, now representing 74% from 29% of total resources.
• Total in-pit constrained resources increased 18%.
• Grade improvement in all mineral categories.
• Current drilling targeting further potential in pit resource upgrade to measured and/or indicated.
• Results fully support continued feasibility study.

Vancouver, British Columbia--(Newsfile Corp. - July 17, 2023) - GoviEx Uranium Inc. (TSXV: GXU) (OTCQX: GVXXF) ("GoviEx or the "Company") is pleased to announce an updated Mineral Resource Estimate ("MRE") for its wholly owned, mine permitted Muntanga Uranium Project in Zambia (the "Muntanga Project"). The Muntanga Project consists of three mining permits that cover some 720km2, and contains five deposits: Dibbwi, Dibbwi East, Muntanga, Gwabi and Njame.

Daniel Major, CEO of GoviEx commented: "Our drilling campaigns in 2021 and 2022 have led to a significant update in the Muntanga mineral resource estimate. This progress is characterized by a notable growth in in-pit resources, a substantial conversion of inferred resources into the Indicated category, and an overall rise in uranium grades. What's more exciting is that this upward trajectory in resource growth persists even under lower uranium prices, such as the USD50/lb used in our Preliminary Economic Assessment (PEA)1. There is also additional potential for further upgrading of inferred resources, thereby expanding the resources that can be included in the feasibility study. These are very promising results and will be integrated into our ongoing feasibility study."

The 2023 updated MRE is the result of extensive infill drilling, including 8,010 metres drilled in 2021 and a further 19,990 metres drilling in 2022, predominately on the Dibbwi East deposit, to further delineate the deposit and convert inferred resources to the indicated category. The mineral resource update included a comprehensive reassessment of previous work and a revised correlation between down-hole radiometric probe data and chemical assays used to convert down-hole radiometric data into equivalent uranium grades (eU3O8) for mineral resource estimation.

Table 1.0 Comparison between 2017 & 2023 Constrained Mineral Resource Estimates

Based on the USD50/lb U3O8, used to define the mining schedule in the 2017 PEA, constrained total pit resources are 36.5 Mlb eU3O8, comprising 34 Mt at 374 ppm eU3O8 for 28.4 Mlb in measured and indicated and 11 Mt at 348 ppm eU3O8 for8.1 Mlb of inferred, highlighting the robustness of the mineral resources at Muntanga. With the quality of the resource estimate improved, higher M&I, higher grade and a notable increase in estimated resources within the constrained open-pit area, we are optimistic that the updated MRE will be favourable to the project economics previously estimated for Muntanga in the PEA, and especially as the ongoing drilling is targeting conversion of more inferred resources into indicated resources.

As per the regulations applicable in 2017 when the Company released its NI 43-101 Technical Report1, the MRE reported did not need to be constrained by pit shells based on any particular uranium price, as almost all mineralisation at the time occurred within 125 m of surface with uranium grades that were, in general, considered to have a reasonable prospect for eventual economic extraction ("RPEEE") by open pit mining. The cut-off grade used for reporting the 2017 MRE was 100 ppm eU3O8.

The 2023 MRE is disclosed including an additional constraint applied to comply with the RPEEE and is accordingly reported within a constraining open-pit shell based on a uranium selling price of USD70/lb U3O8 and a 100 ppm eU3O8 cut-off grade. The updated 2023 MRE is presented in Table 3.0.

To facilitate a comparison between the 2023 and 2017 MRE, Table 2.0 below provides an assessment on the impact of a constraining open-pit shell based on uranium selling price of USD70/lb U3O8 and a 100 ppm eU3O8 cut-off grade on the 2017 MRE.

Table 2.0 Comparison of 2017 unconstrained and constrained mineral resources

The 2017 constrained mineral resources are based on a fixed uranium price, and should uranium prices increase, a conversion of additional material into a constrained mineral resource would be anticipated.

Based on the drilling completed in 2021 and 2022, an updated mineral resource estimate has been prepared by SRK Consulting (Canada) Inc. ("SRK"). The Mineral Resource is that portion of the resource estimate which has been constrained within an open-pit shell, considering reasonable mining, processing and general and administrative cost, geotechnical parameters and processing recoveries. SRK considers that the material reported as a Mineral Resource fulfils the requirement by the CIM Guidelines of having a RPEEE through open pit mining.

A summary of the Mineral Resources for all deposits comprising the Muntanga Project are presented in Table 3.0 below.

Table 3.0Mineral Resource Statement*, Muntanga Uranium Project, Zambia, effective date of March 31, 2023

*Notes:

1. The effective date of the mineral resource statement is March 31, 2023. The QP for the estimate is Cliff Revering, P.Eng., an employee of SRK Consulting (Canada) Inc.
2. Mineral resources are prepared in accordance with CIM Definition Standards (CIM, 2014) and the CIM estimation of Mineral Resources and Mineral Reserves Best Practise Guidelines (CIM, 2019).
3. Mineral Resources are reported at a cut-off grade of 100 ppm eU3O8.
4. Mineral resources are constrained within an optimized pit shell using a uranium price of USD70/lb U3O8, mining costs of USD2.90/t, processing costs of USD8.00/t ore, additional ore mining costs of USD0.50/t ore, G&A costs of USD1.50/t ore, royalty of 5% on U3O8 price and a discount rate of 8%.
5. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves in the future.
6. All figures have been rounded to reflect the relative accuracy of the estimate.

Analysis of the open-pit shell used to constrain the MRE highlights that there are still inferred category mineral resources that have the potential to be converted to indicated resources with additional drilling. That would enable them to be included in the economics related to any future feasibility study, as the examples below indicate. This work is currently under way as part of this year's previously announced drilling program.

In conclusion, the updated MRE for the Muntanga Project is a testament to GoviEx's strategic focus and commitment to maximizing the potential of its vast resource base. As the only uranium developer with two African projects ready to begin development and near-term production, GoviEx is well placed to benefit from future growth.
