Talovskoye Prospect: Sampling Results

East Star Resources Plc (LSE:EST), which is defining mineral resources in Kazakhstan for the energy revolution, is very pleased to announce the results from sampling at the Talovskoye prospect on the Rudny Altai Volcanic Massive Sulphide ("VMS") belt in Kazakhstan. The Talovskoye prospect sits on licence RA1, which is 100% owned by East Star and appears to have many geological similarities to the high-grade current and past producing VMS deposits on the belt.

Highlights:

• Mapping identifies high-grade Cu/Ag mineralisation only 17km from the Nikolovskoye processing plant
• Samples include:

o 6.30% Cu, 5.19% Pb, 0.81 g/t Au and >100g/t Ag

o 8.44% Cu, >20% Pb, 1.1 g/t Au and > 100 g/t Ag

o 2.58% Cu, 11.35% Pb, 3.84 g/t Au and >100 g/t Ag

• Extensive sulphide mineralisation, with outcropping gossans largely obscured under waste from historical small-scale mining
• Existing infrastructure and proximity to the Nikolovskoye processing plant offers potential for low-cost development
• Further exploration is required on this high-priority target with drilling planned for 2024

Alex Walker, East Star CEO, commented:

"The Talovskoye Cu/Ag prospect is shaping up to be another very interesting target within our VMS portfolio. The detailed mapping undertaken this year has informed our geological understanding and strengthened our view that this is a prospect we should be drilling at the nearest opportunity.

Largely covered by waste from small-scale mining and only 17km by road to the Nikolovskoye processing plant, the Talovskoye prospect has the potential to be a very low-cost development opportunity should it get to that stage."

Next Steps

The discovery of high-grade Cu/Ag mineralisation confirms the importance of Talovskoye, informed by geological understanding driven by detailed mapping conducted earlier this year. With winter approaching, East Star will continue the geological review of the prospect to determine the additional steps, if any, required to refine targeting ahead of the 2024 drilling season.

Verkhuba Assay Update

Final assays (excluding gold) have been received from the laboratory, with the Company undertaking further QA/QC protocols prior to the results being confirmed and released to the market which is expected in the next 1-2 weeks.
