FireFly Metals reports 42m @ 6.1% CuEq and 9.8m @ 16.5% CuEq at Green Bay, feeding into economic studies. The high-grade core zone could boost early production economics.
FireFly Metals has released more drilling results from its Green Bay copper-gold project in Newfoundland, and the numbers are hard to ignore. The company reported 42 metres grading 6.1% copper-equivalent and a separate 9.8-metre intersection at 16.5% CuEq. Both come from the high-grade core zone that FireFly is targeting for an upscaled restart.
These assays will feed into the economic studies now being completed. The core zone already holds 8.8 million tonnes at 3.9% CuEq in the measured and indicated category, with another 10.9 million tonnes inferred. The continuity of high-grade material at depth and along strike matters because it lets the mine plan pull higher grades early in the production schedule. That improves payback periods and project returns.
FireFly managing director said in the release: “These results will be included in the economic studies, which are in the process of being completed, enabling us to demonstrate the financial benefits of such a rich core of mineralisation.”
Green Bay is a former producing mine. FireFly is studying a restart with expanded throughput. The company has six rigs drilling underground and is running regional exploration in parallel. The goal is to grow the resource while completing technical studies.
The economic studies are due in the coming months. They will determine whether the high-grade core can support a low-capital restart with strong early margins. For context on the broader gold and copper market dynamics that underpin these economics, the project sits in a jurisdiction with established mining infrastructure and a history of production.
