East Star Resources (LSE:EST) - Drilling Through 2027 on Kazakhstan Copper and Gold Assets
Interview with Alex Walker, Director & CEO of East Star Resources PLC Our previous interview: https://www.cruxinvestor.com/posts/east-star-resources-lseest-secures-2nd-copper-jv-agreement-with-rulikha-project-in-kazakhstan-11740 Recording date: 14th October 2026 East Star Resources (LSE:EST) is a London-listed copper and gold explorer in Kazakhstan. Its main appeal is the deal structure, not any single deposit. CEO Alex Walker has put partners in place who fund the most expensive and dilutive stages of mine development. East Star keeps a fixed share of each project in return. The most advanced asset is Verkhuba, a JORC inferred resource of 20.3 Mt at 1.16% copper, 1.54% zinc and 0.27% lead. Hong Kong Xinhai Mining Services Limited is funding the project to production. East Star would then own 30% of a planned 1 Mtpa operation, with no debt repayment, capital payback or waterfall. Xinhai has given an indicative capital cost of about $65 million for the plant. Under East Star’s structure, a cost overrun does not change its percentage. Two rigs are drilling to upgrade resource confidence, and the programme is expected to pass 5,000 metres before winter. The results will feed a mine plan and the mining licence application, which is already in preparation. Metallurgical test work is starting, replacing recovery data from around 1990. Rulikha is the second copper project. It is a VMS exploration target of up to 23 Mt at 2.4% copper equivalent, based on historical drilling. East Star has signed a binding Heads of Agreement with Kazakh partner Nova Ltd. The definitive JV agreement is still under negotiation. If the partner builds the mine without debt repayment, East Star keeps 25%. If the partner chooses a debt structure, East Star receives 12.25% of allocated revenue until the debt is repaid, then 35%. A five-hole, roughly 1,500-metre programme began on October 2026 to verify the historical intersections. A resource drill-out would follow if they are confirmed. The third leg is gold where Endeavour Mining is funding exploration across two Areas of Interest in northern Kazakhstan. It earns 51% by spending US$5 million during a two-year Stage 1, followed by a US$20 million phase. After a PFS, Endeavour would hold 80% and East Star 20%. The JV targets a discovery of 3 million ounces or more. It has applied for more than 930 square kilometres of licences focused on intrusion-related gold systems. Endeavour is also East Star’s largest shareholder. Walker estimates the shares trade at less than 10% of future NAV, assuming both copper projects reach production. He argues that Kazakhstan’s low labour, power and fuel costs, its infrastructure and its long mining history support strong project margins. He also points to drilling costs of a third to a half of those in Chile or Australia. Over the next year, catalysts include Verkhuba drilling results, the Rulikha verification results and execution of the definitive JV agreement, and Endeavour licence grants. Walker’s stated goal is for Verkhuba to be in construction by the end of 2027.
