Rome Resources Reports Maiden Mineral Resource Estimate and Strong Progress at Bisie North

Rome Resources final results: Bisie North maiden resource is the big takeaway

Rome Resources has used its 2025 final results to underline one main point: Bisie North is no longer just an exploration idea. The company has now published a maiden Mineral Resource Estimate, or MRE – the first formal estimate of how much mineral is in the ground based on drilling.

For a junior explorer on AIM, that matters. Markets usually give more credit to a defined resource than to a long list of promising drill intercepts, because it starts to put scale and potential value around the story.

Key figure	2025 result

Equity raised during 2025	£2.1 million
Loss before tax	£1.263 million
Operating loss	£1.359 million
Exploration assets	£13.246 million
Core drilling completed since AIM admission	9,780m

Bisie North maiden Mineral Resource Estimate shows real scale in tin, copper and zinc

The headline resource is split across two areas: Mont Agoma and Kalayi. Together, the maiden MRE confirmed about 11kt of contained tin, alongside 45.9kt of copper, 86.2kt of zinc and 1.46Moz of silver.

That is important because it gives Rome two slightly different development angles. Kalayi is a simpler tin-only play, while Mont Agoma is a broader polymetallic project with copper, zinc, tin and silver.

Kalayi tin resource could be the faster route to monetisation

Kalayi carries an inferred resource of 0.33Mt at 1.36% tin, containing 4.47kt of tin, using a 0.85% tin cut-off grade. In plain English, that means Rome has defined a relatively small but decent-grade tin resource so far, and management believes newer drilling has hit wider high-grade zones that have not yet been included.

The company is clearly pushing Kalayi as the near-term commercial angle. Management said work has started on a small-scale mining operation at Kalayi to produce tin from near-surface workings and help support conversion to a full exploitation licence.

Mont Agoma adds copper, zinc and silver upside

Mont Agoma looks broader and more complex, but potentially larger in value terms because of the by-products. The inferred resource stands at 3.16Mt with a net smelter return cut-off of US$90 per tonne, grading 1.45% copper, 0.19% tin, 2.72% zinc and 14.3g/t silver.

That equates to 45.9kt of copper, 6.1kt of tin, 86.2kt of zinc and 1.46Moz of silver. Metallurgical test work was also encouraging, with copper recovery of 97% in rougher flotation and zinc recovery of 99.1%, which is the sort of technical detail investors like to see because it hints the ore may be processable.

Why Rome Resources shareholders should care about the 2026 drilling at Kalayi

The 2025 figures are only part of the story here. Since the year end, Rome has completed another 3,250m of drilling at Bisie North, and management says broader Kalayi intercepts from the 2026 campaign have verified the geological model.

That is one of the more interesting lines in the release. If those wider intercepts feed into an updated MRE in mid-2026, Kalayi could move from a modest starter resource into something with much more heft.

Rome is also taking part in an airborne geophysical survey across the northern margin of the Bisie tin granite. That is a technical way of saying it is using airborne tools to map what may sit below surface and generate fresh drill targets.

Rome Resources funding, cash burn and going concern risk investors cannot ignore

Now for the part that matters just as much as the geology: cash. Rome ended 2025 with £1.418 million in cash, down from £4.485 million a year earlier.

That drop is not surprising for an explorer that spent heavily on drilling. During 2025, net cash used in operating activities was £2.158 million, while exploration expenditure in investing activities was £2.916 million.

The company raised £2.1 million in equity during 2025 and then around £1.6 million in the first half of 2026, including £1.59 million gross in April 2026. Even so, the accounts are very clear that more money will be needed.

The directors say the group will need additional funding in early 2027 to meet liabilities as they fall due. The auditors did not qualify the accounts, but they did highlight a material uncertainty related to going concern. That is a standard warning sign for early-stage miners with no revenue, but it still matters because future dilution is likely.

So the investment case remains the usual junior mining balancing act: better drill results can support a higher valuation, but every new funding round can water down existing shareholders if the share price is weak.

DRC political risk is real, but operations appear to have stabilised

Rome did have a 40-day shutdown in May 2025 after M23 forces advanced towards Walikale. That will remind investors that operating in the Democratic Republic of Congo brings extra risk, however good the rocks may be.

That said, the company reported no further trigger points after the restart, and no lost-time or environmental incidents during the period. Management also pointed out that the nearby Alphamin operation has continued exporting since restarting, which helps support the case that mining activity in the area is still workable.

Canada option and bigger ownership at Bisie North could add more upside

Rome is not stopping with the DRC. It has signed an option agreement over an early-stage tin-tungsten-molybdenum-indium play in New Brunswick, Canada, with fieldwork planned in summer 2026 and possible drilling in 2027.

This is interesting, but it is firmly second-tier for now. The main value driver remains Bisie North, and Canada looks more like early optionality than something the market should heavily price in today.

More immediately relevant is the move to increase Rome’s ownership in its DRC licences. The company announced non-binding heads of terms that could take its interest in Mont Agoma SARL from 51% to 81% and effective ownership of Kalayi Tin SARL from 52% to 71%, in exchange for up to 600,000,000 new shares. Those deals were not completed at the date of signing the report.

If completed, that could be good strategically because Rome would own more of any future upside. The catch is obvious: more shares means more dilution.

My view on Rome Resources final results and what happens next at Bisie North

On balance, this is a positive operational update wrapped inside a financially normal but still risky junior mining set of accounts. The big win is that Rome now has a maiden resource, more drilling behind it, and signs that Kalayi may be improving.

The less comfortable bit is that this business still has no revenue, needs more money in early 2027, and operates in a jurisdiction where security headlines can change quickly. That does not kill the story, but it does mean investors need to keep one eye on the drill core and the other on the cash balance.

If the mid-2026 resource update shows those wider Kalayi intercepts genuinely add meaningful tonnes and contained tin, Rome could have a stronger hand in future fundraises. If not, the market may focus harder on dilution and country risk.

For now, the company has done the bit explorers must do: turn drilling into a resource. The next test is whether it can turn that resource into something bigger, better owned, and a step closer to commercial reality.
