East Star Resources Plc provided an update regarding resource modelling of the Verkhuba copper deposit on the Rudny Altai Volcanic Massive Sulphide ("VMS") belt, Kazakhstan, following extensive fieldwork (including drilling) in 2023. The company has updated its resource model for the Verkhuba copper deposit using more accurate data derived from 12 months of detailed fieldwork, which included geological mapping, a Light Detection and Ranging ("LIDAR") topographical survey, and drilling. The results of the remodelling have provided the Company with a higher degree of confidence in the historical data and the development potential of the deposit.

As such, and in discussion with the Company's independent experts, AMCConsultants ("AMC"), East Star has instructed AMC to undertake the work required to produce a maiden JORC Inferred resource. This work is expected to take around one month and will be ready prior to the commencement of the 2024 field season.
