Halo Minerals Reports Strong Progress at Playa Verde Copper Tailings Project Following Audited Results

Halo Minerals’ 2025 audited results are really about one thing: the company has gone from being a shell with financing baggage to owning a potentially attractive copper development project in Chile. The headline event was the acquisition of Copper Bay Limited, which owns the Playa Verde copper tailings project. Tailings are old mining waste, and Halo’s pitch is that reprocessing them can be lower risk and lower cost than building a brand-new mine.

For retail investors, that matters because this is no longer a vague exploration story. Halo now has a defined asset, approved environmental clearance, a fresh AIM listing, and updated project economics that look punchy on paper. The flip side is equally important – it is still pre-production, still lossmaking, and still needs to execute a lot before cash starts coming in.

Halo Minerals audited results: the key Playa Verde numbers investors need to know

Metric	Figure
Total Mineral Resources	53.44 million tonnes at 0.24% Cu
Ore Reserves	32.2 million tonnes at 0.25% Cu
Contained copper in total resources	125,820 tonnes
Contained copper in ore reserves	79,359 tonnes
NPV10	US$154.1 million
IRR	50.9% after tax
Target annual payable copper output	8,640 tonnes
Operating cost	US$2.19 per pound of copper produced
Year-end cash	£356,000
Loss after tax	£1.651 million
IPO fundraise after year end	£4 million

That NPV10 is the project’s net present value using a 10% discount rate, and IRR is the internal rate of return – basically, two standard ways of judging whether a mine looks economic. On those assumptions, Playa Verde looks strong. But remember, those figures are based on ore reserves only and assume copper at US$5.30 per pound and gold at US$4,300 per ounce.

Playa Verde copper tailings project looks materially de-risked after EIA approval

The strongest operational takeaway is permitting progress. Halo said the Environmental Impact Assessment, or EIA, was unanimously approved by the Chilean Ministerial Committee in October 2025. For a development company, that is a major box ticked and removes one of the bigger early-stage doubts.

The project is also described as technically de-risked because it already has a Preliminary Feasibility Study, a Definitive Feasibility Study and an updated Competent Person’s Report, or CPR. In plain English, this is not a grassroots concept – there is already a substantial pile of technical work behind it.

Halo now wants to optimise the DFS into a bankable feasibility study, secure ancillary permits and move toward a final investment decision. That is the right sequence. It also tells you the company is still in the development queue rather than on the brink of immediate production.

Halo Minerals balance sheet: better story after the IPO than at 31 December 2025

The reported year-end balance sheet was not especially pretty in isolation. Cash was just £356,000, total equity was negative £296,000, and accumulated losses had reached £41.324 million. There was no revenue disclosed, which is normal for a pre-production developer, but it underlines the fact that this is still a funding-and-progress story rather than a trading business.

That said, the important bit came after the balance sheet date. Halo completed its AIM admission on 30 March 2026 and raised £4 million before expenses. The company also says it converted outstanding loan notes and is now debt free, which is a meaningful clean-up of the capital structure.

That makes the headline numbers look better than the year-end snapshot suggests. In other words, investors should read these accounts as a before-and-after story – weak year-end liquidity, followed by a much stronger funding position once the IPO completed.

Why the Copper Bay acquisition structure is smarter than it first looks

Halo acquired Copper Bay for total consideration of US$7.5 million, but crucially that is payable in two US$3.75 million instalments only once production milestones are hit – at 7,500 tonnes and 15,000 tonnes of copper or copper-equivalent production. That is a sensible structure for a junior miner because it reduces immediate cash strain.

In the accounts, that deferred consideration was initially recognised at £3.52 million and carried at £3.751 million at year end after discount unwinding and foreign exchange movements. The company is effectively saying: we pay more when the project starts delivering. For shareholders, that is much better than handing over all the cash upfront.

Halo Minerals project economics are attractive, but they are not the same as cash in the bank

On paper, Playa Verde has real appeal. Halo says the planned operation would process 5 million tonnes per annum and target annual output of 8,640 tonnes of payable copper, with roughly 85% as LME Grade-A cathode and 15% as concentrate carrying a gold credit. The mine life based on reserves is seven years.

The CPR economics are the sort of numbers that get small-cap investors interested. An after-tax NPV10 of US$154.1 million and an IRR of 50.9% suggest a project with genuine potential, especially as management argues tailings projects can have lower geological and operational risk than primary mines.

But this is where discipline matters. Attractive economics do not mean guaranteed financing, construction, commissioning or production. Plenty of small mining companies have looked great in studies and then stumbled on the messy stuff.

Big upside from the maritime concession, but this part is firmly not banked yet

One of the more interesting angles is the offshore potential. Halo has filed a maritime concession application covering what it estimates could be approximately 100 million tonnes of copper-bearing tailings in the bay. If secured, that could materially extend the life of the planned operation.

Still, investors should keep this in the right bucket. These rights are not yet secured, and this is upside rather than core value today. It is promising, but not something I would bake into the investment case until the legal position is nailed down.

What I think these Halo Minerals results mean for retail investors

My view is that this was a positive set of results overall, mainly because the strategic progress was much more important than the profit and loss account. Halo has acquired a proper project, got environmental approval, updated the economics, cleaned up debt, and raised £4 million on AIM. That is a lot of heavy lifting in one period.

The negative is obvious too. Halo remains a single-asset, pre-production miner with no revenue, continuing losses and more permit, optimisation and financing work ahead. That means execution risk is still high, and any investment case depends on management turning technical promise into actual production.

So the sensible conclusion is this: Halo looks more credible today than it did a year ago, and Playa Verde appears to have enough substance to deserve attention. But this is still an early-stage copper developer, not a cash machine. If you like junior miners, the story has improved sharply. If you hate project risk, nothing in this RNS changes that.

Next Halo Minerals share price catalysts after the 2025 audited results

• Optimisation of the DFS and progression to a bankable feasibility study
• Securing ancillary permits needed for development
• Progress on the maritime concession application
• Publication of the first ESG baseline report and local hiring plan
• Any update on project financing and timing to final investment decision

For now, Halo has given the market a better-quality story with more substance behind it. The next step is proving that the story can keep moving from paperwork to production.
