Mine Life19.5 years (as of Jan 1, 2022)
The Madaouela Uranium Project comprises five deposits have been developed to a high level of confidence. All major mining permits already secured.

The economic analysis of the production case includs the Mineral Reserve and recovery of a molybdenum by-product (NPV of USD 120 million at a discount rate of 8 %, with an IRR of 12.7 %).

As a result of recoverable molybdenum being present in assay and metallurgical test work, two additional cases are considered which are the indicated and inferred Molybdenum with a positive NPV of USD 125 million at a discount rate of 8 %, with an IRR of 12.85 %, and an indicated, inferred, and unclassified Molybdenum case with a positive NPV of USD 140 million at a discount rate of 8 %, with an IRR of 13.27 %.

Deposit Type

  • Sandstone hosted

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 dep ........

Summary:

Open Pit Mining – Miriam
The Miriam open pit operation will be a conventional drill, blast, truck and shovel operation. Ore loading will be undertaken on 6 m benches, mining to the orebody contacts, down to 0.75 m flitches where required. Two 12 m3 excavators will be used to load 91 tonne haul trucks in the pit with a 6.4 m3 front-end loader on the stockpiles and for backup in the pit.

It is planned that all open pit material will require drilling and blasting. Drilling and blasting will be undertaken on 12 m benches in the waste for the upper benches above the orebody. Within the orebody, both ore and waste will be drilled and blasted on 6 m benches. The ultimate pit walls will be pre-split on 12 m benches. Infill drilling will be undertaken on 24 m benches. All blasting activities will be undertaken by a contractor.

Loading will be undertaken in a similar approach to nearby operations, on 6 m benches with mining to the orebody contacts, down to 0.75 m flitches in ore where required for grade control. Two 12 m3 excavators will be paired with 91 t haul trucks in the pit, with a 6.4 m3 front-end loader on the stockpiles and for backup in the pit.

Most High grade (HG) material is direct fed to the crusher, with an expected 10 % ROM rehandle. 1 % of HG is stockpiled short-term due to the mine planning objectives. Almost all Low grade (LG) material is stockpiled up to 720 kt, and fed to the crusher in batches over the last two years of the mi ........
