East Star Resources Plc announced a maiden JORC Inferred Mineral Resource (" Resource") for the Verkhuba Copper Deposit ("Verkhuba" or "the Deposit") in the Rudny Altai belt, Kazakhstan of 20.3Mt @ 1.16% copper, 1.54% zinc and 0.27% lead using a whole deposit cutoff grade of 0.86% copper equivalent ("CuEq"). Highlights: 236,000 tonnes of contained copper @ 1.16%; 313,000 tonnes of contained zinc @ 1.54% Upside from lowering the cutoff grade for the open pit portion of the deposit in future economic models. Following the publication of this Resource, the planned 2024 drilling programme is intended to progress the open pit development concept through to a stage where economic feasibility can be demonstrated, and a mining licence application process can begin.

East Star is in the process of receiving offers from strategic partners for a potential joint venture, farm-out, or sale of Verkhuba. Background East Star has been exploring the Rudny Altai volcanogenic massive sulfide ("VMS") belt since 2019 with the first licences being acquired in this region in late 2020. Through methodical acquisition and review of historical data and application of modern geophysics, low detection limit assays, new geological models and other analytical tools, the Company has been able to initially assess the potential of the Deposit and progress targeting for additional discoveries in this rich but underexplored mineral belt.

The benefits of Verkhuba include: Shallow high-grade intersections which confirm open pit development potential; Established processing infrastructure (owed by third parties) including two mills with combined spare capacity of 1.4M tonnes per annum within 52 km of the Deposit as well as roads, power and water infrastructure. The historical mineral resource estimate for Verkhuba was updated from the March 2023 Exploration Target due to: 1. The value was assumed based on work completed and documented in historical reports. All modelling was completed using Micromine software.
