SnapshotThe Madaouela Uranium Project comprises five deposits that have been developed to a high level of confidence.

GoviEx has successfully advanced the Madaouela Project from its initial exploration phase to the publication of its feasibility study in late 2022.

During 2023, GoviEx updated its Environmental and Social Impact Assessment, commenced Front-End Engineering Designs and initial ground works, including the construction of an access road and started exploitation. In June 2024, the company received its radiological certificate, which is a regulatory requirement prior to starting mining operations.

On 4 July 2024, the Government of the Republic of Niger withdrew GoviEx’s rights over the perimeter of the Madaouela mining permit.

The Company reserves the right to challenge the decision to withdraw the mining rights before the competent national or international jurisdictions.

Government of Niger 20 % Indirect
Goviex Uranium Inc. 80 % Indirect
Compagnie Miniere Madaouela SA (“COMIMA”) was incorporated in July 2019 to hold the Madaouela mining permit and owned 80% by the Goviex Uranium and 20% by the Niger government.

On August 18, 2025, GoviEx Uranium Inc. announced that it has entered into an arrangement agreement with Tombador Iron Limited to complete a reverse takeover that will see GoviEx shareholders become the majority shareholders of an Australian listed company to be renamed Atomic Eagle Ltd.

Pursuant to the Arrangement Agreement, Tombador will acquire 100% of the issued and outstanding Class A common shares of GoviEx. On closing of the Transaction, GoviEx shareholders will own 75%1 of the Combined Company while Tombador's existing shareholders will hold 25%1 of the Combined Company.

Summary:

The Madaouela Uranium Project comprises five deposits have been developed to a high level of confidence: Marianne, Marilyn, Miriam, MSNE and Maryvonne.

The Madaouela deposits exhibit classic characteristics of uranium sandstone deposits common the world over.

The Marianne-Marilyn (M&M) deposit is a nearly flat tabular body of mineralisation that spans approximately 7 km (N70E direction) by 3 km across in plan, and the deposit thickness varies from 0.2 to over 2 m (average thickness of about 1 m).The mineralisation occurs at depths from about 30 m on the eastern end of Marilyn, to approximately 60 m in depth in the middle of the Marianne-Marilyn deposit, up to 120 m in depths on the west extensions of Marianne; below the relatively flat topographic surface.

The MYVE deposit is a nearly flat tabular body of mineralisation that spans approximately 1 km (N70E direction) by 0.6 km across in plan, and the deposit thickness varies from 0.2 to 1.8 m (average thickness of about 1 m). The mineralisation occurs at depths from about 105 m in the east to 120 m in the west.

The MSNE deposit spans approximately 2.8 km (N60E direction) by 2.4 km across in plan, and the deposit thickness varies from 0.2 to 2.4 m (average thickness of about 1 m). The mineralisation occurs at depths from about 140 m in the north to 130 m in the south. There is discontinuous uranium mineralisation within the N60E trending UA channel which also varies in orientation depending on position within the channel. Thin uranium mineralisation is also present at the base of the Tarat, in the south of the deposit.

The MSCE deposit is relatively flat and spans approximately 2.0 km (N70E direction) by 0.4 km across in plan, and the deposit thickness varies from 0.4 to 3.4 m (average thickness of about 1.4 m). The mineralisation occurs at depths from about 110 m in the east to 160 m in the west. Thin uranium mineralisation is also present at the base of the Tarat, in the south of the deposit.

The MSEE deposit is affected both by an east-west channel as well as the Madaouela fault in the south-east. Significant mineralisation is irregularly distributed, but the deposit area roughly spans approximately 2.2 km (E direction) by 1.7 km across in plan, and the deposit thickness varies from 0.2 to 2.4 m (average thickness of about 1.0 m). The mineralisation occurs at depths from about 95 m in the north to 140 m in the south, on the downthrown side of the Madaouela fault.

The Miriam deposit mineralisation is a combination of the Guezouman-Talak contact mineralisation present at the other deposits, but also thicker, stacked horizons focussed about a north-westerly trend. The deposit is also affected by the Madaouela fault in the south-east, similar to MSEE. The deposit area spans approximately 2.5 km (N40W direction) by 1.5 km across in plan, and the deposit thickness varies from 0.2 to over 30 m thick localized along the north-westerly structures. The mineralisation occurs at depths from about 65 m in the southeast to 120 m in the north-west.
