Executive summary

• Rook I construction advanced across engineering, procurement and site development, with progress reported on scope, schedule and budget; licensed construction began June 8, 2026.

• Q3 net loss narrowed year over year, largely due to non-cash convertible-debenture fair-value changes; construction and exploration spending reduced cash and working capital.

Financial highlights

• Q3 net loss was C$22.265M, or C$0.03 per share, versus C$129.220M and C$0.23 in Q3 2025; 9M net loss was C$103.751M versus C$266.847M.

Outlook and guidance

• Temporary ground freezing is planned for March 2027, with shaft sinking targeted for July 2027; 2027 remains the expected peak capital expenditure year.

• Q4 priorities include shaft civil preparations, detailed engineering, major contract awards and site development; additional financing will be required to complete construction and fund planned exploration.

• Additional uranium sales agreements are expected in coming periods; utility discussions are advanced, and contracting aims to retain exposure to market prices at delivery.

• An initial PCE resource statement is targeted for the start of Q3 2027, subject to assay timing and further resource definition, engineering, environmental studies and permitting.

• Production cost estimates remain just under US$10/lb, with all-in cost of ~US$14/lb, based on the August 2024 estimate.
