Dalny Licence Drilling Results, Kazakhstan
Gold bearing mineralised system with shallow intersections of
potentially economic grades and widths
East Star Resources Plc (LSE:EST), which is defining mineral
resources in Kazakhstan for the energy revolution, is pleased to
provide results from diamond drilling on the Dalny licence of the
Chu-Ili Orogenic Gold Belt in Kazakhstan. Results show shallow
intersections of potentially economic grades and widths from the
Alatagyl northern zone with planning of follow-up exploration work
ongoing.
Highlights:
-- 19 drill holes totalling 1,860 m were drilled on the Alatagyl target on the Dalny licence
-- Programme was designed to test mineralisation where East Star
sampled rock chips up to 27.4 g/t Au (announced 30 June 2022) and
historical drilling and trench results indicated gold
mineralisation
-- Best intercepts (at a cut-off grade of 0.3 g/t Au) include:
o DL_18 - 4 m @ 2.74 g/t from 24 m and 12 m @ 2.03 g/t from 31
m
o DL_19 - 1 m @ 1.32 g/t from 34 m and 2 m @ 0.93 g/t from 51
m
o DL_14 - 3 m @ 0.51 g/t from 55 m
o DL_15 - 3 m @ 2.09 g/t from 21 m
-- Confirmed presence of gold on the Dalny licence - further
analysis is underway to determine next steps to progress
exploration
Alex Walker, East Star CEO, commented:
"We are pleased with the results from the Alatagyl northern area
which indicate a gold bearing mineralised system with shallow
intersections of potentially economic grades and widths.
We are undertaking a review of the drill results against the
historical data to expand our knowledge of the mineralisation
system and determine the scope of the follow-up exploration
programme."
Drilling Summary
Prior to drilling, three sites were identified in the
north-eastern part of the Dalny licence: the Alatagyl western zone;
the Alatagyl northern zone; and Alatagyl far northern zone.
At Alatagyl far north, based on the results of past sampling and
mapping by the East Star geological team, two drill holes were
designed to test surface expression of quartz with alteration.
DL_18 and DL_19 were drilled 22 m apart to depths of 112 m and 121
m respectively with results including DL_18, 4 m @ 2.74 g/t from 24
m and 12 m @ 2.03 g/t from 31 m; and DL_19, 1 m @ 1.32 g/t from 34
m and 2 m @ 0.93g/t from 51 m. The geology includes thin quartz
veinlets and associated alteration with intense sulfide
mineralisation, hosted in sandstones.

In the drilling at the Alatagyl west site, the East Star team
had mapped veins, collapses of north-western trending quartz and
many trenches and small historical workings. This area incorporated
the largest surface footprint and best historical sampling results
from both East Star and historical reports. 12 holes were drilled
with only trace gold mineralisation found.
Logging and Processing of Core Samples
The core was logged on site by East Star geologists. After
logging and photography, core was transported to Karaganda where it
was cut; samples were taken, weighed, and recorded.

Laboratory and Analytical Work
The analyses were conducted at Tsentre Geoanalit in Karaganda,
Central Kazakhstan. This laboratory is accredited by the State
Standard of the Republic of Kazakhstan. The accreditation
certificate was registered in the State Register of the State
Certification System of the Republic of Kazakhstan on 14 June 2005
(No. Z 7100000.06.10.00373). The laboratory is not accredited by
the international ISO17025 standard. A number of flame atomic
absorption spectrometers of various generations are in operation
(PerkinElmer AAnalyst200, PerkinElmer Aanalyst400 and PerkinElmer
PinAAcle 900F) linked to Winlab32 AA Flame - Manual Analysis
Control software. The Dalny samples were dissolved in aqua regia
and subjected to initial spectrograph analysis followed by analysis
of gold using AAS (using one of several PerkinElmer PinAAcle 900F
units). Samples were prepared at the Tsentrgeolsmyemka facility
near Karaganda. Sample preparation comprised weighing of the
sample, drying, crushing to -1 mm, splitting of 300 g of sample by
cone and quarter, and milling using one of several rod mills. A
sieve was available to check the crushing quality. Samples were
milled and half of the milled sample was placed in a hand labelled
paper envelope and dispatched to the analytical facility and the
other half was kept on-site. The rejected material is kept for five
years. Cores are kept in a shed at a different site in
Karaganda.
A QA/QC programme was used to evaluate the quality of the 2,051
total assay results. In total 193 QA/QC samples (or 9%) were
inserted into the sample stream including - 65 CRMs, 64 field
duplicates and 64 blanks. The QA/QC samples returned satisfactory
results demonstrating that the data are acceptable for early-stage
exploration. It should be noted that the high-grade assays are
likely to be under reporting gold concentrations as the aqua regia
solution is unlikely to completely dissolve the gold in the
samples. This is supported by the generally slightly lower than
expected gold concentrations seen in the CRM analyses.
