FireFly assays point to high-grade start for Green Bay restart

FireFly Metals released a new batch of drill results from its Green Bay copper-gold project in Newfoundland, with the standout intersection running 11.5 metres at 11.1% copper and 2.1 grams per tonne gold, or 13.2% copper-equivalent. The company said the six-rig underground program is targeting the higher-grade VMS and Core Zones, and these assays will feed directly into the upcoming mineral resource estimate update and the preliminary economic assessment due by the end of August.
The current resource stands at 50.4 million tonnes at 2.0% copper-equivalent in the measured and indicated category, plus 29.3 million tonnes at 2.5% copper-equivalent in inferred. FireFly has been drilling since the November 2025 MRE to convert much of that inferred tonnage into the higher-confidence M&I buckets. The goal is to get at least 70% of the mine plan into M&I for the economic study, which would also support a maiden ore reserve declaration before the end of 2026.
