East Star Resources Plc
("East Star" or the "Company")
New VMS Licence Award at Rulikha Deposit
East Star Resources Plc (LSE:EST), which is exploring for copper and gold in
Kazakhstan, is pleased to announce it has been awarded a new exploration
licence - 3631-EL (the "Licence"), encompassing the remaining part of the
induced-polarisation (IP) anomaly north of the Rulikha Deposit.
With the entire IP anomaly at Rulikha now under 100% ownership by East Star,
execution of the next phase of exploration can begin. Additional historical
drilling within the newly awarded Licence has also been included in East
Star's ongoing assessment of both the Rulikha Deposit and its geological
interpretation of the Rulikha IP anomaly. Some highlighted intersections from
the historic drilling are below.
Highlights of Historical Intersections Within New Licence:
· 11.4m @ 9.8% Zn, 3.1% Cu and 1.1% Pb from 196.6m
· 6.9m @ 17.6% Zn, 1.0% Cu and 3.3% Pb from 237.4m
· 11.2m @ 5.5% Zn, 0.32% Cu and 1.2% Pb from 236.0m
· 8.7m @ 5.4% Zn, 0.3% Cu and 0.3% Pb from 256.2m
180 historical drill holes are currently being modelled to provide an
Exploration Target and assess the Reasonable Prospects for Economic Extraction
(RPEE).
Alex Walker, East Star CEO, commented:
"East Star is expanding its VMS opportunities through this additional highly
prospective exploration licence, adding a second soviet-era deposit to our
East Region assets. Although permitting is expected to be more arduous due to
proximity to a settlement, at less than 2km from an existing rail line and
11km from an underfed mill, we are eager to assess the potential economic
viability of this deposit, in a region which has been mined since the
mid-1700s.
In remodelling such detailed historical data, East Star will be able to assess
the reasonable prospects for economic extraction prior to on the ground
exploration and therefore, like Verkhuba, we will undertake a low-cost
exploration campaign to verify the data and convert the exploration target to
a JORC Resource.
We are grateful for the support from the Shemonaikha District in allowing us
to apply for the Licence and we look forward to updating the market on future
exploration activities."

History of the Rulikha Deposit
The Rulikha Deposit and geophysical targets are situated about 33km northwest
from East Star's 100% owned Verkhuba Deposit (JORC MRE of 20.3Mt @ 1.16%
copper, 1.54% zinc and 0.27% lead). Located within the
Rulikhinskoe-Vydrikhinskoe Ore Field in the Shemonaikha District of East
Kazakhstan, the Rulikha Deposit is a VMS polymetallic deposit primarily
explored for zinc, copper and lead. The Rulikha Deposit was part of a broader
geological exploration effort in the region, conducted by the East Kazakhstan
Geological Exploration Expedition under the Ministry of Geology of the USSR
and later the Republic of Kazakhstan.
The Rulikha Deposit was discovered in the 1940s and delineated during
exploration up to the 1980s, followed by detailed prospecting from 1989-1992.
The major historical work programmes included:
· 1940-1950s: Early prospecting by the Shemonaikha Party of the Altai
Exploration Group identified polymetallic mineralisation. A consolidated
report in 1957 (Utrobin et al.) calculated GKZ resources for the Rulikhinskoye
(Rulikha) deposit.
· 1960s-1970s: Geological and geophysical work by the Shemonaikha
Geological Reconnaissance Party (GRP) and Priirtyshskaya Party refined the
geological structure and mineralisation of the deposit.
· 1978-1983: Detailed prospecting by the Minsk and Ubin GRPs of the
Shemonaikha GRP targeted the Rulikhinsko-Vydrikhinsky and Talovsko-Rulevsky
areas, further delineating mineralisation.
· 1989-1992: Deep exploration drilling to assess the mineralisation
potential of deeper units (up to 1000-1200m).
Based on the historical reports, it seems that no further exploration was
undertaken since 1992. The last significant exploration programme in 1989-1992
included significant drilling and sampling efforts:
· Total Drilling - 6,785 linear metres of core drilling across 12
exploration boreholes. Drilling grid for Rulikha Deposit: 200 x 100m for C2
category resources (GKZ resource categorisation not typically used in modern
resource estimates), 400 x 100m or 300 x 200m for P1 category.
· Geochemical Sampling - 737 geochemical samples collected.
· Geophysical Logging: - 6,607 linear metres of gamma logging.
The results of the historical exploration found that the Rulikha Deposit hosts
VMS-polymetallic mineralisation, primarily copper, zinc and lead, with minor
gold and silver. Mineralisation is localised in tuffs, volcanic sediments and
extrusive units from the Middle-Upper Devonian boundary. Mineralisation is
associated with vein-type and stratiform ore lenses. Metallurgical or
processing test work for the Rulikha Deposit has not been completed to date.

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 multiple
exploration strategies:
· Volcanogenic massive sulphide (VMS) exploration, which to date
includes a deposit 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
