East Star Resources Plc announced the results of an induced polarisation (IP) survey from the Rulikha drill target area on 13 May 2025. The survey identified two high chargeability trends spanning approximately 1,550m west to east and 1,040m north to south. These anomalies exhibited highest amplitudes of approximately 50m V/V and were located approximately 100m below surface.

Rulikha IP Survey Results
Priority 2025 drill target demonstrating strong geophysical anomalies
Further to the 24 April 2025 announcement, East Star Resources Plc (LSE:EST), which is exploring for copper and gold in Kazakhstan, is pleased to announce the results of the induced polarisation ("IP") survey from the Rulikha high priority drill target area in East Kazakhstan.
This area shows two distinct east-west striking high chargeability trends, in the same geological units as the known Rulikha Deposit. These anomalies are large, spanning approximately 1,550m west to east and 1,040m north to south and are open at depth. They are both strong, with the highest amplitudes reaching approximately 50m V/V and lie from approximately 100m below surface.

Results from the IP survey of the Talovskoye high priority drill target area are expected to follow shortly.
Alex Walker, East Star CEO, commented:
"This large and very strong undrilled IP anomaly is hosted in the same geological unit as both the Rulikha Deposit, only a few hundred metres to the south, and the 50Mt-plus Artemyevsky Deposit, approximately 18km to the northwest. We have all the permissions already in place to test the north and eastern parts of the target. I'm very much looking forward to getting the drill rig turning."
Survey Details
The Rulikha IP Survey was conducted as a 100m pole-dipole in a north-south line direction on 200m line spacing and a 1,600m line length at a frequency of 0.125Hz. Measurements were carried out in a profile-based configuration using a three-electrode forward and reverse setup (AMN-MNA), with simultaneous recording on 32 channels and electrode spacing of 100 m.
Smart Geophysics from Kazakhstan conducted the survey using GDD GRx8-32 receivers and the GDD Tx4 transmitter. Quality control and interpretation was conducted by Mitre Geophysics Pty Ltd out of Australia.

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.
