What Frontier Lithium has updated

The June 2026 technical information on Frontier Lithium's investor relations page presents revised operating cost and revenue assumptions for the Spark deposit, part of the company's PAK lithium project in northwestern Ontario. The document refines mine plan metrics, projected production volumes and estimated life-of-mine averages for spodumene concentrate output, building on earlier feasibility and PEA work.

Market data from TSX Venture price pages show the stock trading below its 12-month high but above recent spring lows, leaving the chart in a mid-range consolidation pattern that reflects cautious investor sentiment around junior lithium names.
