Key competitive advantages that position Roughrider as an elite underground development project include:
- high grade operation with 2.36% U3O8 Life of Mine feed grade,
-
one of the lowest capex profiles in
Canada and -
location in the
Eastern Athabasca Basin , where future development will benefit from proximity to power, roads, and thePoints North Landing airport and construction facility.
Additionally, we see significant potential for further value creation as we advance the project through the prefeasibility stage, supported by recent exploration drill results and the discovery of the Roughrider North Deposit.
Roughrider is poised to benefit from uranium and nuclear energy's growing prominence to address

Mine Plan
The initial economic assessment envisions that the Roughrider deposit will be mined using the longhole stoping method utilizing retreat mining in a transverse stope orientation with various orientations between the three main mineralized zones. Various underground mining methods were considered; however, longhole stoping was ultimately selected to reduce cost. Development will be located to the south of the deposits and will be accessed using a ramp decline which will also be the primary source of fresh air ventilation. Exhaust shafts will be used to ventilate the mine.
Ground freezing will be used to control water inflows into the main decline to a depth below the unconformity as well as into the three mining zones. Freeze wells will be installed from surface around the perimeter of each zone with active freezing starting at least 12 months prior to mining. Figure 1 was generated by UEC as a conceptual image of the conventional underground mine. Further details of proposed mining and milling methods are set out in the Technical Report Summary.
The initial construction focus is on the development of the decline, ventilation and secondary egress from surface (red to yellow). Once the decline reaches the deposit, initial focus will be on the Roughrider West ("RRW") deposit with the decline held while levels and ventilation are developed in this area (green). Mining then progresses to the Roughrider East ("RRE") deposit (cyan) and finally Roughrider Far East ("RRFE") deposit (blue). See Figure 2.

Based on prior metallurgical test work, the following conclusions can be made:
- The comminution test work showed that Roughrider samples are soft in nature with an average Bond Ball Mill Work Index of 10.6 kWh/t.
- Agitated tank leach test results showed that Roughrider mineralization is amenable for uranium extraction via atmospheric acid leaching. On average 98.5% of extraction can be achieved within 12 hours of leach retention time at 50°C with a grind size of 250 µm. Further, it was found that there was no significant difference in dissolution and extraction of uranium from the different deposits (RRW, RRE and RRFE).
- Two different approaches (strong acid strip with uranyl peroxide precipitation and ammonia strip with ammonium diuranate precipitation) were examined for production of final yellowcake product. It was found that organic extraction followed by strong acid strip produced higher quality yellowcake meeting refinery specifications compared to the ammonium sulfate strip method.
- Tailings neutralization and effluent treatment test work based on the standard approaches used in the
Athabasca region indicated that effluent quality meeting the MDMER guidelines can be achieved.
The Technical Report Summary provides for the construction of a tailing management facility ("TMF") to store the uranium tailings produced from processing. The TMF will be located approximately one km northeast of the proposed processing plant on gently sloping terrain. Thickened slurry tailings will be deposited into three adjacent storage cells sequentially constructed over the LOM. The design incorporates a double liner seepage containment system and a 'pervious surround' rock filter. This approach will allow for staged TMF cell construction and progressive reclamation. Containment will be enhanced by construction of a filter rock drain system used successfully at other uranium operations and identified as the 'pervious surround' approach. The storage of tailings solids below grade will reduce risk and promote secure physical containment.
At closure, the water cover will be pumped out of the cell and a cover of soil and geomembrane layers will be placed over the tailings surface. With the multi-cell design, it will be possible to progressively reclaim the TMF storage cells during the operational phase.
Capital Expenditure
The capital and operating cost estimates are based on a 400 t/d processing throughput. The cost was estimated based on the mine plan and process flowsheet. All costs are reported in US dollars and the

Resource Update and Exploration
The 2024 mineral resource estimate that is set out in the Technical Report Summary has been prepared in accordance with the requirements of S-K 1300. To meet the requirement of reasonable prospects of eventual economic extraction, the mineral resource estimate is reported within a constrained mineable shape optimizer as informed by a breakeven cut-off grade of 0.30% U3O8. The mineral resource estimate is reported diluted, including waste and mineralization below cut-off.
The mineral resource estimate set forth in the Technical Report Summary is summarized in Table 7. No Mineral Reserves have been estimated at the project.
