 IP Survey of VMS Copper Targets

 

Survey targeting undrilled existing known anomalies at historical mines and
deposits

 

East Star Resources Plc (LSE:EST), which is exploring for copper and gold in
Kazakhstan, is pleased to announce the re-start of an induced polarisation
("IP") geophysical survey in the Rudny Altai belt in the East Region of
Kazakhstan. The survey is concentrating on the Rulikha and Talovskoye
anomalies and is designed to delineate these high impact 2025 drill targets.
Rulikha and Talovskoye are two volcanogenic massive sulphide ("VMS") deposits
in a similar geological setting to, and around 33 km from, East Star's
Verkhuba Copper Deposit (see Figure 1).

Highlights:

·    Rulikha target: East Star surveys have delineated an electromagnetic
("EM") anomaly and several highly chargeable IP anomalies within a few hundred
metres to the north of the Rulikha deposit, which was historically reported to
contain 14.3 Mt @ 1.2% Cu, 3.5% Zn, 0.28 g/t Au, and 13.5 g/t Ag(1)

 

·    Talovskoye target: An historic high-grade mining area where East Star
reported two shallow chargeable zones on the northern line and a larger
chargeable zone towards the south-west(2). The 50m spaced IP infill lines are
designed to provide further data on the larger south-west IP anomaly

 

·    Both targets are within 11km of the Nikolaevsky processing plant with
spare capacity

 

Alex Walker, East Star CEO, commented:

"The best place to find a mine is near an existing one and these strong
geophysical anomalies below and adjacent to known deposits make for very
promising drill targets. The IP survey we have restarted this week is the last
stage in finalising the targets for drilling this season.

East Star has spent three years finding the best targets in the East Region
and getting them drill ready, covering more than 800km(2) of our own licences
and visiting 17 mines across the belt to assist in our geological
understanding and targeting. We're also in the process of collecting and
digitising the historical Rulikha deposit drill hole database and will provide
an update on this work in due course."

Further Information

Rulikha IP Anomalies

The chargeability models show an east-west trending chargeable zone across the
entire southern part of the survey area. The chargeable zone becomes stronger
towards the east. There is also a second highly chargeable zone just to the
north of this trend. These two zones are strongest (>40 mV/V) on the
easternmost line, and both are around 180m to 200m deep. These two highly
chargeable zones are good drill targets for potential disseminated sulphide
mineralisation and have never been drill tested. While the southern anomaly is
over 850m long, it is thought to continue to the east and the current survey
is designed to confirm the strike extent of the anomaly prior to drilling in
2025.

 anomaly locations

 

 

Rulikha EM Anomaly

A strong, complex EM response defined by a large, low resistivity zone in the
basement and a coincident chargeable response. The core of the anomaly is
around 320m deep. The coincidence of the HeliTEM anomalies, large low
resistivity zone and chargeable response suggests this is a target for VMS
mineralisation that warrants drill testing.

 

Further, within the envelope of the EM anomaly, an historical drill
intersection reported 8.1m at 3.6% Zn from 296.5m and 4m at 5.9% Zn from 395m.
High grade zinc sulphide (sphalerite) does not typically provide an EM
response and therefore does not explain the EM anomaly. It does, however,
indicate a highly mineralised system which could contain a copper-rich massive
sulphide zone as the source of the EM anomaly.

 

Talovskoye IP Anomaly

An historical mining location, reported as 3.9 Mt @ 1.87% Cu, 5.4% Pb, 11% Zn,
0.3 g/t Au and 34.5 g/t Ag(3), made up of a number of thin and shallow, very
high-grade massive sulphide pipes. East Star's sampling of these pipes in 2023
returned grades including:

 

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

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

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

 

The hill contains extensive sulphide mineralisation, with outcropping gossans
largely obscured under waste from historical small-scale mining. The 2024 IP
survey reported two narrow shallow zones on the northern line where East Star
sampled very high-grade massive sulphide rock chips. A larger chargeable zone
was registered southwest of the main hill and historical workings. East Star
has planned 50m spaced infill IP lines, which are designed to provide further
data on the larger south-west trending IP anomaly.

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

 

 Location of East Star's projects in the Rudny Altai belt

 

·    Copper porphyry and epithermal gold exploration, with multiple
opportunities for Tier 1 deposits, supported by an initial $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
