ASX Copper Stocks: Why FireFly Metals is down 12% YTD despite copper at record highs

Copper is up 18% year-to-date and trading at record highs. A rush of shipments into the US ahead of potential import tariffs, production downgrades at almost every major producer and data centre demand have all fed the bull case. In this series, I take a closer look at the ASX-listed copper complex, one name at a time.

FireFly Metals (FFM) is often touted as a potential takeover target. It's a pre-production play trading around the $1.5 billion mark and sitting on a fairly chunky copper resource.

The company acquired its now-flagship Green Bay Project in Canada for $65 million in late 2023, inheriting a resource of 39.2Mt at 2.1% copper equivalent (CuEq). The Measured and Indicated resource now sits at 60.2Mt at 2.4% CuEq, including a high-grade zone of 18.1Mt at 4.3% CuEq.

It's worth noting that FireFly has raised over $420 million since late 2023 ($95m in May 2024, $139m in December 2025 and $190m in August 2026). So no, the market cap hasn't gone 23-fold from $65 million to $1.5 billion. There's been a fair bit of dilution along the way.

What makes FireFly interesting is that it's got a sizeable resource, and its latest Preliminary Economic Assessment (PEA) highlights some solid project economics and a slated first production in mid-2029. In a world where copper projects are being acquired left, right and centre, that combination makes it both a takeover candidate and, in its own right, a company trying to join the bigger producer leagues.

The PEA in a nutshell

The PEA outlined two scenarios:

• 1.8Mtpa base case: NPV of $2.2bn, IRR 41%, 32-year life, ~50kt CuEq/yr over 14 years (peak 61kt), initial capital $513m net of tax credits, payback 1.9yrs, C1 cost of US$2.05/lb CuEq (US$1.17/lb net of by-products)

• 4.6Mtpa upscale: NPV of $3.0bn, IRR 39%, 22-year life, ~90kt CuEq/yr over 11 years (peak 106kt), initial capital $547m plus $476m expansion capital, payback 3.7yrs, C1 cost of US$1.84/lb CuEq (US$1.02/lb net of by-products)

• At spot metal prices (18 Aug 2026): NPV rises to $3.5bn and $5.0bn respectively

• Timeline: DFS and maiden Ore Reserve 1Q27, FID and construction in 1H27, first concentrate mid-2029

The 1.8Mtpa base case runs 4,800 tonnes a day off truck haulage for an average 50,000 tonnes of copper equivalent a year at steady state. The initial capital bill is $513 million net of Canadian refundable tax credits. While the 4.6Mtpa alternative adds a 1,450-metre hoisting shaft and a second process train, lifting steady-state output to roughly 90,000 tonnes of copper equivalent a year and shortening mine life to 22 years from 32. The extra $476 million of expansion capital is expected to come from base case cash flow.

The economics of both cases assume copper at US$5.00/lb, gold at US$3,500/oz and silver at US$44/oz. Copper spot on 18 August was US$6.60/lb, 32% above the study assumption. At those prices, the base case net present value goes from $2.2 billion to $3.5 billion and payback falls from 1.9 years to 1.3 years.

In a note titled "Too big to ignore", Macquarie said the delivery of the PEA was a "key de-risking event for Firefly and demonstrates the attractiveness of Green Bay."

What makes FireFly interesting

This is one of my favourite charts from Macquarie. It's extremely dated (February 2025) but highlights the scarcity of larger cap pure-play copper miners on the ASX (which has only gotten worse).

It shows how, back then, there were only three copper producers with market caps above $1 billion, and one of those, Metals Acquisition Corp (MAC), has since been taken out by South African gold miner Harmony for ~$1.6 billion, a 21% premium. The other takeaway is that FireFly is the largest copper company on the ASX whose asset isn't yet in production.

Barry FitzGerald made the case last month that the corporate development teams at Sandfire, South32 and Mineral Resources would have been first in line to read the Green Bay PEA.

• Sandfire (SFR): Produces ~154,000t CuEq from Spain and Brazil and is openly looking to add projects. FitzGerald rates it the best strategic fit, as it already runs underground polymetallic ops in developed jurisdictions.

• South32 (S32): Sold its aluminium assets to Alcoa for A$7.8 billion and scrapped its 40% payout ratio, which looks a lot like preserving firepower for a big copper acquisition.

• Mineral Resources (MIN): Chris Ellison has said he's looking at a couple of copper deals and wants to partner with an owner of a near-shovel-ready project. Green Bay fits that description almost too neatly, though MIN as the operator of an underground Canadian mine is a harder sell.

Where does that leave Firefly?

FireFly is arguably the ASX's next mid-tier copper producer. The project economics stack up and there's obvious leverage to a higher copper price. At a ~$1.5bn market cap, with a resource big enough to move the needle for its larger peers, a takeover wouldn't be entirely left field either.

That said, the share price is actually down 12% year-to-date. FireFly has walked into the most challenging stretch for valuation upside, with feasibility studies, a final investment decision and construction by the first half of 2027. To investors it feels like nothing is happening, when in fact this is exactly when the most is happening on the ground.

Share prices tend to go sideways through this window because the market is switching from valuing an explorer on the tonnes it can find to valuing a producer on the earnings and cash flow it can generate. And these days, building a project carries real cost and timeline risk on top of that.
