HEAD GRADE INCEASES .. David Bronkhorst, Denison's Vice President Operations, commented, "The metallurgical testing completed to date demonstrates that uranium can be consistently recovered from Phoenix cores at levels significantly higher than the 10 g/L extraction rate used in the PFS – giving rise to a decision to adapt future unit operation metallurgical tests to use a UBS head-grade of 15 g/L.
A 50% increase in head-grade is expected to translate into meaningful optimization of previously estimated operating parameters and processing plant designs while maintaining the same level of annual uranium production – with the potential to reduce operating costs related to on-surface processing activities, and initial capital costs associated with the processing plant."
