VMS Drilling Update
Results from Rulikha North and Talovskoye confirm mineralisation within
expected lithologies, and improve targeting for 2026 drilling
East Star Resources Plc (LSE:EST), the Kazakhstan-focused gold and base metals
explorer, is pleased to provide an update on drilling activities which have
been completed at the Rulikha North and Talovskoye West targets.
Highlights
· 120m of disseminated sulphides, including 90m @ >20% pyrite at Rulikha
North
· Footwall stringer zones indicating proximity to a massive sulphide source
· Follow up work programmes planned in 2026
Alex Walker, East Star CEO, commented:
"We have identified a fertile hydrothermal cell at Rulikha North, which shows
that there is a large system, requiring further exploration. We're excited to
follow up on this target in 2026 in the hope of delineating another ore body
in this hugely productive and underexplored region.
Whilst clearly further away from the source, the Talovskoye target did
intersect mineralisation and, based on the proximity to past producing mines,
further exploration work remains justified.
We are excited to explore these targets further for a massive sulphide source
with geophysics and, if those results are positive, follow up with drilling in
2026. Our East Region VMS strategy is producing encouraging exploration
results, and we've now started to demonstrate that positive results can be
monetised, as per our recently announced JV agreement for the development of
Verkhuba."
Rulikha North
Drill hole RU_25_DD001 is located 1.6 km north of the Rulikha Deposit and
tested the centre of the chargeability anomaly to a depth of 400m. Drilling
confirmed that the Rulikha North IP anomaly does contain disseminated
sulphides and stringer veinlets with minor Zn-Pb (+Cu) mineralisation. The
results include three important horizons:
· Increased Cu horizon - 195.00 - 210.00m at 456 ppm Cu (background copper is 65
ppm)
· Zn-Pb stringer - 350 -392m at 0.5% Pb, 0.8% Zn and 339 ppm Cu
· Zn stringer - 390-392.00m at 0.27% Zn
These results confirm the presence of a large 1.5 x 1.0 km hydrothermal
alteration cell, previously outlined by the Company in its announcement on 13
May 2025 (Figure 1).
Figure 1: Plan view showing the large extent of the Rulikha North and
Talovskoye IP anomalies
These hydrothermal alteration cells are a requisite for a VMS deposit to form.
In addition to the disseminated sulphides, East Star noted alteration and
stringer veins typical of the style of mineralisation expected immediately
adjacent to a massive sulphide ore body (Figure 2).
Figure 2: Stringer pyrite veins with sericite alteration observed at 319.75 m
The initial geological interpretation indicates that a fertile system has been
intersected, but the source of the sulphides was not intersected; therefore,
the drill hole is proximal to a potential VMS-style deposit (Figure 3). As
such, the results provided the confirmation that East Star required from this
phase of drilling, including confirming mineralisation within the expected
lithologies as well as demonstrating proximal alteration signatures.
Additional exploration is therefore warranted with the likely exploration
programme to include a ground electromagnetic ("EM") survey, aimed at directly
targeting the massive sulphides within the system.

North anomaly. Zone 1 - 4 represents the footprint of the hydrothermal cell
(note alternative geological interpretations may exist, and further work is
needed to confirm the presence of mineralisation)
Talovskoye West
Drilling at Talovskoye West was completed with a single drillhole
(TAL_25_DD001) drilled to a depth of 305.50m. This hole aimed to test a
discrete IP chargeability anomaly, previously outlined by the Company in its
announcement on 15 May 2025 (Figure 1).
The hole intersected volcaniclastic and breccia lithologies with minor
alteration associated with stringer veinlets of sulphides. The hole did
intersect a small, mineralised interval - 265.10 to 265.90m at 0.8 % Zn, 0.37
% Pb and 0.3% Cu. The sulphide content combined with relatively small
alteration intervals indicate that the footwall alteration pattern was not
intersected (Figure 4). The Company views the anomaly as unresolved and
additional geophysics, likely to include ground EM, are required to determine
the location of any potential massive sulphides in the system.
