Bradda Head Lithium reported additional surface sampling results from its Whistlejacket lithium project in Arizona, U.S., and announced the start of Phase 3 drilling.
Of the latest 41 rock samples, 19 returned grades above 0.50% Li₂O, 15 exceeded 1.00% Li₂O, and 13 exceeded 1.50% Li₂O. The highest reported sample returned 3.90% Li₂O.
The results represent the third and final batch from the company’s 2026 rock-chip sampling program.
Bradda Head said Phase 3 drilling will focus on testing the continuity, geometry and scale of spodumene-bearing pegmatites at depth.
The Whistlejacket project is being advanced under an option-to-joint-venture agreement with Kennecott Exploration.
