About East Star Resources Plc

East Star Resources is focused on the discovery and development of copper and gold in Kazakhstan. East Star's management are based permanently on the ground, supported by local expertise. The Company is pursuing three exploration strategies:

· A Volcanogenic Massive Sulphide (VMS) discovery with a maiden JORC MRE of 20.3Mt @ 1.16% copper, 1.54% zinc and 0.27% lead, in an infrastructure-rich region, amenable to a low capex development

· Copper porphyry and epithermal gold exploration, with multiple opportunities for Tier 1 deposits, initially supported by an initial US$500k grant from BHP Xplor in 2024.

· Sediment-hosted copper exploration with Getech where the initial targeting strategy is at no cost to East Star.
