East Star Resources Reports Transformational Year with Major JVs and Strategic Investment

East Star Resources 2025 results – why this really was a transformational year

East Star Resources has used the word “transformational”, and in this case I think that is fair. For a small, pre-revenue explorer, signing a US$25 million gold earn-in with Endeavour Mining, lining up a US$65 million development funding route for Verkhuba with Xinhai, and bringing Endeavour in as a 14.3% shareholder is a serious change in scale.

That said, this is still an exploration company, not a cash-generating miner. The big positive is that major partners are now helping fund the heavy lifting. The big catch is that East Star is still loss-making, still diluting shareholders, and still carries going concern uncertainty – even if management says cash should stay positive through 30 June 2027 under its base case.

East Star Resources key numbers from the 2025 final results

Metric	2025	2024
Loss before tax	£2.3 million	£1.1 million
Cash and cash equivalents	£442,000	£678,000
Net assets	£2.4 million	£3.2 million
Total assets	£4.4 million	£3.3 million
Exploration asset carrying value	£1.9 million	£2.4 million
Impairment charge	£1.286 million	£62,000
Basic loss per share	0.54p	0.42p

The headline financials are mixed. The company made no revenue, the annual loss more than doubled, and year-end cash fell to £442,000. On the face of it, those numbers are weak.

But they do not tell the whole story. Trade and other receivables jumped to £2.1 million, mainly because of money due from Endeavour under the convertible loan note and warrant exercise proceeds, both settled in January 2026. So the year-end balance sheet looks tighter than the near-term cash picture probably was in practice.

Why the Endeavour Mining deal matters for East Star shareholders

The standout development is the gold joint venture with Endeavour Mining. In plain English, an earn-in means the bigger partner spends money on exploration to earn a stake in the assets.

Here, Endeavour can invest over US$25 million in staged exploration spending to earn up to an 80% interest in the joint venture vehicle. The initial two-year phase includes US$5 million of committed expenditure for a 51% interest, with East Star keeping a 20% stake even on full earn-in, plus potential bonus payments linked to a maiden JORC resource and Preliminary Feasibility Study.

That is important because East Star is no longer trying to fund all its gold exploration alone. It also says a lot that a FTSE 100 gold producer was willing to back the team, the assets and the country strategy.

My read is simple: this materially improves East Star’s chances of advancing gold projects without repeatedly going back to the market for cash. For retail investors, that lowers funding risk on the gold side, even if it also means East Star gives up majority ownership if Endeavour goes all the way through the earn-in.

Verkhuba copper joint venture with Xinhai could be the biggest practical step forward

The second major deal is with Hong Kong Xinhai Mining Services, which signed a staged farm-in agreement over Verkhuba. A farm-in is similar to an earn-in – the incoming partner spends money to earn a project stake.

Under the agreement, Xinhai may earn up to a 70% interest in Verkhuba through a five-stage investment programme through to production, with estimated investment of US$65 million. East Star says it will be fully carried, meaning it does not have to fund its share of that development spend, while retaining a 30% interest in production.

That is a big deal for a junior explorer. Verkhuba already hosts a resource of 20.3Mt at 1.16% copper, 1.54% zinc and 0.27% lead, so this is not a pure blue-sky story. It is one of the clearest routes in the portfolio from exploration into development.

The obvious trade-off is ownership. East Star gives up control of the asset in exchange for getting it advanced at no further cost. Personally, I think that is a sensible bargain for a company of this size.

Rulikha and the wider East Star copper portfolio still carry major upside

If Verkhuba is the development story, Rulikha looks like the upside engine. East Star now owns the full IP anomaly there, and the company announced a JORC-compliant Exploration Target with an upper limit of 23Mt at 2.4% copper equivalent.

That equates to over 550,000 tonnes of contained copper and is described as nearly double the copper equivalent metal of Verkhuba. Exploration targets are not mineral resources, so investors should not treat that as an economic deposit yet, but it does show why Rulikha matters.

The company also reported sulphides in drilling at Rulikha North and Talovskoye West, and it added two porphyry licences, Piket and Judzha, in recognised belts in Kazakhstan. Those porphyry projects are earlier stage, but they broaden the pipeline.

Snowy gold target and the Kazakhstan gold strategy are getting sharper

Snowy remains 100% East Star and made useful progress in 2025. The company defined a 4km by 1km gold-in-soil anomaly and updated its model to a low-sulphidation epithermal system, which is a style of shallow volcanic gold mineralisation.

Rock chip samples returned up to 1.44g/t gold at surface, and the prospective vein system has been traced for at least 100m of strike, still open to the north. That is encouraging, though it is still early and the key next step is drilling.

East Star also chose to stop pursuing its greenfield sediment-hosted copper strategy in the Teniz Basin with Getech. I actually see that as a positive. Small explorers are usually better when they focus, and East Star now looks more concentrated on the projects with the strongest partner backing and clearest path to value.

What looks negative in the East Star final results

• No revenue: this is still a pure exploration and development story.
• Higher losses: loss before tax rose to £2.3 million.
• Impairment: £1.286 million was written off after licence terminations and relinquishment. An impairment is an accounting write-down when an asset is judged to be worth less than previously recorded.
• Cash burn and dilution: East Star raised £2.4 million in 2025 and still ended the year with £442,000 of cash.
• Going concern uncertainty: the directors explicitly say material uncertainty remains, even though they believe the going concern basis is appropriate.

None of those points should be brushed aside. The market often gets excited by deal flow and ignores the funding reality. Junior miners can still disappoint even with strong partners.

What East Star investors should watch next in 2026

• Progress on establishing and advancing the Xinhai Verkhuba joint venture
• Ground electromagnetic surveys and follow-up drilling at Rulikha and Talovskoye
• Snowy geophysics and drill planning
• Work programmes at Piket and Judzha
• Any update on the re-instatement of East Star shares to trading, which has been applied for but not confirmed in this RNS

That last point matters more than it may seem. A re-instatement to trading affects liquidity and whether investors can properly deal in the shares, so it is a practical issue, not just admin.

My verdict on the East Star Resources 2025 annual results

On balance, I think these results are strategically very positive, even though the statutory numbers are messy. The losses, impairment and going concern warning are real, but the commercial significance of attracting Endeavour and Xinhai is bigger.

East Star now looks less like a small explorer trying to keep plates spinning, and more like a company with credible partners helping to fund both discovery and development. For retail investors, that does not remove risk – far from it – but it does make the story more investable than it was a year ago.

If management can turn the 2025 deal-making into real drilling results, resource growth and project milestones in 2026, then this “transformational year” label will have earned its keep.
