FireFly’s Green Bay project leads Canada in spending efficiency for copper

A recent economic analysis and update for FireFly Metals' (ASX, TSX: FFM) Green Bay project in central Newfoundland highlights its status as one of Canada's most cost-efficient undeveloped copper sites. The preliminary economic assessment (PEA) estimates a A$2.2 billion net present value – discounted at 7% in a base case – with a 42% internal rate of return.

The project requires A$513 million in initial costs and could yield 1.8 million tonnes of copper annually over a 32-year lifespan. Green Bay's capital efficiency surpasses Canada's other undeveloped copper projects, boasting over four times higher after-tax NPV than initial capital expenses compared to Canadian Copper's Murray Brook-Caribou in New Brunswick.

Canada-wide, Green Bay ranks third in NPV for undeveloped copper-gold projects, trailing Seabridge Gold's KSM in British Columbia and Western Copper and Gold's Casino in Yukon. The study underscores Green Bay's potential to become a major player in Newfoundland and Labrador's mining sector, as no primary copper mines operate in the region, with only one gold mine in commercial production.

If put into production, Green Bay could become one of the world's largest copper mines outside multinational conglomerates, according to FireFly Managing Director Steve Parsons. The company plans to release a feasibility study for Green Bay in Q1 next year, followed by a final investment decision by the second half of 2027, with potential mid-2029 commence operations.

FireFly intends to raise A$180 million through equity sales to fund feasibility study advances, resource growth, and early project works, with A$150 million allocated for an ASX institutional placement and the remainder through a Canadian private placement.
