Drilling Update: Verkhuba Copper Deposit, Rudny Altai
Core inspection indicative of strongly mineralised system
East Star Resources Plc (LSE:EST), which is defining mineral
resources in Kazakhstan for the energy revolution, is pleased to
provide an update following visual inspection and logging of core
from drilling at the Verkhuba Copper-Zinc Deposit within the
Company's 803.7 km(2) licence package in the Rudny Altai
volcanogenic massive sulphide ("VMS") belt, Kazakhstan.
Highlights:
-- Visual inspection combined with X-ray fluorescence ("XRF")
readings on core confirm the presence of copper and zinc
mineralisation in the first 4 holes at Verkhuba
-- Copper mineralisation identified in all holes with multiple
massive sulphide intervals recognised
-- Drilling has identified large thicknesses of disseminated
copper mineralisation, not previously acknowledged or assayed in
historical drilling
-- Core is currently being prepared for multi-element assay
including copper, zinc and precious metals (gold/silver)
Alex Walker, East Star CEO, commented:
"We are encouraged by the visual core inspection from within the
Verkhuba Copper Deposit, with much of the drilling correlating with
anticipated mineralised zones from the historical data. Broad zones
of disseminated sulphides with consistent copper and zinc readings
by XRF, along with zones of chalcopyrite-rich massive sulphides,
leaves very little doubt we are in a strongly mineralised system.
Core is currently being prepared for assay which will provide the
data we need to model these results against the historical drill
holes which will hopefully form the basis of a JORC compliant
resource."

Figure 5 VU_23_DD_002_WET_189.3-193.0
Mineralised intersections above 0.5% chalcopyrite include:
-- VU_23_DD_001 contains 24.7m of disseminated sulphide
mineralisation including two intervals of 4.6m and 12.7m from 37m
and 56.4m respectively with estimated content of chalcopyrite
ranging from 1.0% to 10.0%
-- VU_23_DD_002 contains 14.2m of disseminated sulphide
mineralisation with five intervals varying in thickness from 1.3m
to 6.6m with content of chalcopyrite and sphalerite estimated from
1.50% to 15.0% each within a depth interval of 172.2m to 194.4m
-- VU_23_DD_003 contains 56.3m of visible disseminated sulphide
mineralisation starting from 74.7m with content of chalcopyrite
estimated from 0.6% to 9.0%
-- VU_23_DD_004 contains two intervals of 6.4m and 10.6m of
disseminated sulphide mineralisation starting from 55.9m and 86.3m
respectively where content of chalcopyrite is estimated above
0.5%
Visual estimates of mineral abundance should never be considered
a proxy or substitute for laboratory analyses where concentrations
or grades are the factor of principal economic interest. Laboratory
assays are required to determine the presence and grade of any
contained mineralisation within the reported visual intersections
of copper sulphides. Portable XRF is used as an aid in the
determination of mineral type and abundance during the geological
logging process.
