FireFly Metals has delivered a fresh wave of high-grade copper and gold drilling results at its Green Bay project in Canada, setting the stage for an updated Mineral Resource Estimate and a Preliminary Economic Assessment due by the end of August 2026.
- High-grade copper-gold intersections bolster resource confidence
- Resource update to increase Measured & Indicated categories
- Preliminary Economic Assessment on track for August completion
- Six underground rigs active at Ming Mine
- Company well funded with A$196.4 million cash
High-Grade Drilling Underpins Green Bay Resource Upgrade
FireFly Metals Ltd (ASX:TSX: FFM) has reported another batch of compelling high-grade drilling results from its Green Bay Copper-Gold Project in Newfoundland and Labrador, Canada. Highlights include an 11.5-metre intercept grading 11.1% copper and 2.1 grams per tonne gold (13.2% copper equivalent), alongside multiple other thick zones exceeding 8% CuEq. These results are expected to feed directly into a Mineral Resource Estimate (MRE) update and Preliminary Economic Assessment (PEA) due by the end of August 2026.
The latest assays confirm strong continuity and exceptional grade across several key zones, notably the upper Volcanogenic Massive Sulphide (VMS) lenses, the high-grade Core Zone where VMS and footwall stringer mineralisation converge, and the footwall zone itself. The Core Zone alone holds 8.8 million tonnes at 3.9% CuEq in Measured and Indicated categories, with further potential to grow.
Resource Growth and Economic Studies on Track
FireFly’s underground drilling program, featuring six rigs, is focused on converting Inferred Resources into higher-confidence Measured and Indicated categories; crucial for economic modelling and eventual Ore Reserve declaration. The current MRE stands at 50.4 million tonnes at 2.0% CuEq (Measured and Indicated) and 29.3 million tonnes at 2.5% CuEq (Inferred). The upcoming resource update aims to increase the proportion of M&I resources in the mine plan to at least 70%, supporting the economic studies underpinning potential production resumption.
The PEA will explore various development scenarios, including haulage methods and production scales, with a feasibility study expected in the first quarter of 2027. FireFly has also secured conditional environmental clearance from the Newfoundland and Labrador government, enabling early works and permitting progress.
Regional Exploration and Funding Position
Beyond the Ming Mine, FireFly is accelerating regional exploration with three surface rigs testing geophysical targets, including maiden drilling at the Tilt Cove project. These efforts complement the underground focus and aim to identify new discoveries that could further enhance the project’s scale.
Financially, FireFly is well positioned with approximately A$196.4 million in cash and liquid investments as of 30 June 2026, providing a strong balance sheet to support ongoing drilling, economic studies, and early development activities.
Managing Director Steve Parsons emphasised the significance of the high-grade results, stating they will drive early production years in a potential Green Bay restart and are pivotal to the company’s strategy to grow its high-confidence resource base.
Bottom Line?
FireFly’s Green Bay project is shaping up as a high-grade copper-gold contender with robust drilling results and a well-funded pathway toward production, but the market will be watching how the upcoming resource update and economic studies translate into a maiden Ore Reserve and development decisions.
Questions in the middle?
- How will the updated Mineral Resource Estimate affect the mine plan and production profile?
- What development scenarios will the Preliminary Economic Assessment prioritise?
- Can regional exploration at Tilt Cove yield new resources to complement Green Bay?
