NexGen Energy (NXE) is advancing its Rook I uranium project toward construction, with UBS Securities highlighting execution risks across shaft sinking, funding and marketing.
The company is moving Rook I from technical studies into execution, with construction expected to begin in the summer following receipt of a License to Construct earlier this year, the analysts said in a note Monday, adding that the most critical phase is the first 150 to 200 metres of shaft sinking.
To manage this, ground freezing is planned to extend to about 175 metres for the production shaft and about 220 metres for the exhaust shaft. Expected sinking rates of about 1.5 to 2.5 metres per day are "realistic," but material volatility could occur. This overburden phase is expected to be the main driver of both cost and schedule risk, the analysts said.
Once the shafts reach competent basement rock at around 160 metres depth, geotechnical risks and cost variability decline materially, with conventional sinking conditions prevailing. If successful, the most technically challenging phase would be largely de-risked by mid-to-late 2027, the analysts added.
UBS said marketing risk remains key given the scale of Rook I, while funding requirements and structure remain dependent on uranium prices and contracting conditions.
UBS has a buy rating and a price target of CA$20 ($14.5) on NexGen Energy.
