NexGen Energy says Rook I freeze plant is preparing for shipment

NexGen Energy Ltd. TSENXE NYSENXE ASXNXG said on Sunday its freeze plant is preparing for shipment to Rook I, where basement rock begins 100 metres below surface. The equipment is intended to support shaft construction within NexGen's planned four-year build, but the Oct. 11 update gives no dispatch, arrival or installation date.

NexGen shares TSENXE rose 1.46 per cent to C$12.51 at the Oct. 9 close in Toronto, as of 4 p.m. EDT on Google Finance. That close preceded Sunday's procurement update.

NexGen says freezing is required only through the overburden to allow installation of a conventional hydrostatic liner and secure shaft infrastructure in competent basement rock. The company says freezing is permanently removed once the shaft is connected to that rock, allowing the ground to thaw naturally.

The company calls the activity part of the construction critical path and says it is on schedule. NexGen describes delivery as several months ahead of planned installation, without quantifying that lead or announcing a revised build timetable.

The update follows NexGen's Oct. 10 report that its concrete batch plant had arrived ahead of schedule at Rook I. That equipment is intended to supply concrete for shaft pads, the mill terrace and other infrastructure.

Vancouver-based NexGen is developing the 100 per cent-owned Rook I uranium project in Saskatchewan's Athabasca Basin. Its March 5, 2026 approval release said the Canadian Nuclear Safety Commission had approved the environmental assessment and issued a Licence to Prepare Site and Construct.

The March release said NexGen had already made a final investment decision, with official construction to commence in summer 2026. It put potential annual uranium production at up to 30 million pounds when Rook I is fully operational.

"As per the Rook I Project schedule, construction will take 4 years from commencement," the company said in the March 5 release.

At June 30, 2026, NexGen reported C$756.2 million of cash and C$214.1 million of short-term investments in its interim financial statements. The same balance sheet listed convertible debentures at a carrying value of C$612.4 million.

For the six months ended June 30, 2026, company-wide cash expenditures on mineral property, plant and equipment were C$54.5 million. Cash spending on exploration and evaluation assets was C$88.6 million over that period.

NexGen's October 2026 site presentation says subgrade work on the airstrip extension is complete. The runway is being extended to 5,840 feet to accommodate jet aircraft.

The airstrip extension is scheduled for completion in December 2026, according to NexGen's October presentation.
