A London-listed Kazakhstan explorer running an unusual carried-JV model — today it signed its second fully-carried copper JV, letting proven partners fund development while it keeps minority upside and almost no dilution.

East Star Resources is a small LSE explorer that has quietly built one of the more interesting funding structures in the junior space. Rather than self-fund the enormous cost of developing copper and gold in Kazakhstan, it brings in proven partners on fully-carried terms — the partner pays for drilling, feasibility, permitting and construction, and East Star keeps a free-carried minority stake. Today's news, an RNS headlined '2nd Copper JV Agreement' (1 September 2026), is the latest and clearest example: East Star signed a JV over its 100%-owned Rulikha copper project with Nova Ltd, with local developer Orion — the team that built the profitable Karshyga and Kamkor copper mines — as operator. Nova/Orion fund 100% of future work to earn up to ~65-75%, while East Star retains at least 25%, free-carried, and government approval for a Q3/Q4 2026 drilling programme was confirmed alongside. This follows the Verkhuba copper JV with Xinhai Mining (March 2026) and a gold JV with FTSE 100 producer Endeavour Mining, which also holds ~14% of the company. The shares rose to a 52-week high of 4.90p on the news. The trade-off: East Star now owns minority carried stakes rather than 100% of anything, so its value increasingly depends on partners delivering — in a higher-risk Kazakhstan jurisdiction.
East Star's strategy is to discover scale, then let a funded partner carry it toward production. Today's Rulikha JV completes a hat-trick of carried deals across its portfolio.
100%-owned VMS copper project with an Exploration Target of ~15-23 Mt at 1-2% copper (plus gold/zinc/lead/silver credits). Now carried by Nova/Orion, who fund the drilling — approved today for Q3/Q4 2026 — to convert it toward a JORC resource.
East Star's most advanced asset — a JORC Inferred resource of 20.3 Mt at 1.16% Cu, 1.54% Zn, 0.27% Pb in the Rudny Altai belt. In a JV with Xinhai Mining, which funds development (~US$65M) to earn up to 70%; a mining-licence application is targeted this year.
Epithermal and alkalic-porphyry gold targets (Snowy, Piket) across the Stepnogorsk/Karaganda belts, funded by Endeavour Mining, which can earn up to 80% while East Star keeps ~20% carried.
Well-capitalised for its activity level precisely because partners fund the heavy spend; ~£2.4M raised in late 2025 (incl. Endeavour's £1.8M strategic investment), ~550M shares in issue after the Feb 2026 loan-note conversion.
East Star has essentially turned itself into a portfolio of funded call options on Kazakh copper and gold. Each carried JV converts a 100%-owned but unfunded asset into an operator-led, fully-funded path toward production, while East Star preserves cash and avoids the dilution spiral that grinds down most single-asset juniors. Today's Rulikha deal is the third leg of that structure and arguably the strongest signal yet, because Nova/Orion are builders with a track record of taking Kazakh copper deposits into profitable production. The forward question is the mirror image of the strength: value now depends on partners actually funding and delivering, and East Star holds only minority interests, so the upside per project is capped at its carried percentage. Layer on Kazakhstan jurisdiction risk — permitting, licence security, geopolitics — and the fact that Rulikha is still an Exploration Target rather than a resource, and this is a clever, lower-dilution way to hold early-stage optionality, not a de-risked producer.
From our mining research database — how advanced & proven the asset is (not a valuation).
Resource-definition / pre-development stage (3/6) — Verkhuba carries a JORC Inferred resource (resource 1/2) and is moving toward a mining-licence application, while Rulikha is still an Exploration Target. Kazakhstan scores low on jurisdiction (1/3) for permitting, licence-security and geopolitical risk. The score does not capture the carried-JV funding model, which materially reduces East Star's dilution and financing risk.
Overall quality read: Framework grade: C- — Still a pre-revenue explorer, so it grades low on profitability — but the carried-JV model lifts it above the average junior: dilution and financing risk are unusually contained because proven partners (Xinhai, Nova/Orion) and a FTSE 100 backer (Endeavour) fund the heavy spend, and Verkhuba gives it a real JORC resource. Held to C- by Kazakhstan jurisdiction risk, minority-only carried interests, and the fact that value now depends on partners delivering rather than on East Star's own execution.
