Material Impact

This is a Routine - Positive exploration update that does not materially alter the near-term production or cost profile.
The stock has declined approximately 49% from its January 2026 high of $2.05 to the current $1.05, reflecting market concerns over AISC creep and metallurgical variability.
The drill results are incremental to the ongoing $25M, three-year exploration program and do not trigger a re-rating of the asset base or mine life in the immediate term.
The market's reaction has already priced in the transition period and cost pressures, making this news a standard operational update rather than a catalyst.
