·      Samples were taken from half drill core through sulphide or oxide mineralised intervals.

·      Sampling was conducted through mineralized intervals, with samples taken 2 meters into the hanging wall and footwall for intervals larger than 3 meters. For smaller intervals (<2 meters), only the mineralized portion is sampled.

·      Sample quality is ensured by a structured scheme, including blanks, certified reference materials (CRM), and duplicates.

·      Banks are inserted at the beginning and end of large, mineralized intervals, but not for smaller isolated intervals.

·      CRMs are inserted at every 50th and 100th sample to monitor consistency.

·      Coarse duplicates are taken every 40th and 80th sample, focused on mineralized portions, and 5% of mineralized pulps are sent for external lab analysis.

·      A total of 191.4 meters of core were sampled, with 216 core samples collected, including 12 blanks, 5 CRMs, and 5 duplicate samples.

·      Core samples were prepared by ALS Kazgeochemistry LLP, using standard methods like crushing, sieving (<70% passing 2mm), and milling (>85% passing 75μm).

·      Samples are analysed using the ME-ICP41 method for routine analysis, and for over-limit ore samples, the ME-OG62 method is used.

·    Drilling was conducted using stand HQ sized diamond drilling technique.

·    Positive Group Kazakhstan undertook drilling.

·    Drill core was orientated using a REFLEX Act III orientation tool. All holes that weren't drilled vertically were orientated once solid core was intersected.

·    After drilling was completed, all holes were survey at 50 m intervals using the REFLEX EZ TRAC survey tool

·    Core recovery was measured by East Star geologists, an average of 96 % recovery was recorded for the three completed drill holes.

·    Through the mineralized intervals, core recovery was 97% and greater.

·    There is no relationship between Cu, Pb or Zn grades and recovery.

·    There does not appear to have been any bias due to sample material loss/grain

·    East Star geologists undertook core logging.

·    Quantitative data for mineralization, lithology, structure, alteration, oxidation, and weathering was logged.

·    All recovered core was logged and photographed before and after sampling

·    Half core samples were collected for processing, the remaining half core is securely stored at East Star's core storage facilities in Verkhuba Village

·    Samples were crushed into chips; the chips were passed through a riffle splitter several times to obtain 500 g samples for milling. Crushed sample duplicates were analysed to confirm homogeneity of crushed samples.

·    Blank granite material was also inserted into the sample stream to ensure no contamination occurs during crushing or milling.

·    ALS laboratories weigh samples before and after sieving, to ensure that the thresholds for size fractions are met for each sample.

·    Aqua regia is a partial digest method well suited to base metal analyses, the method at ALS is internationally recognized and provides precise and accurate analyses.

·    Standard assay quality controls are used by the laboratory and East Star inserted QA/QC samples to evaluate and confirm the assay results. All QA/QC samples reported within limits.

·    Significant intersections were confirmed visually by East Star's exploration manager, no independent verification has been completed to date.

·    Logged data was inspected by East Star's exploration manager, any changes to the logged data were made before data was sent to Rock Solid based in Perth, Australia to be added to the maintained SQL database

·    Drill holes were surveyed using Garmin GPSMAP 62S handheld GPS device. DGPS surveys are planned once all drilling is completed.

·    Grid system WGS83, UTM44N

·    Some errors were noted in the elevation readings (from 5 - 14 m errors), these were adjusted to the elevation values of the LIDAR topography survey at the coordinates of the drill hole.

·    A drone LIDAR survey was conducted in 2023. The survey conducted by Aurora Geophysics used a drone mounted LIDAR sensor (DJI Zenmuse L1 Lidar on a DJI Matrice 300 RTK Combo D-RTK 2 drone) with a base station (Trimble R12 and Trimble TDL 450 radio modem). Flight lines were 90 m apart, and the resolution produced was 3.44 cm/pixel. The processed digital terrane model was checked against control points.

·    Historical drilling was drilled along NW-SE trending lines, the lines were spaced between 200-300m apart and drill holes were spaced between 100 and 250 m apart.

·    Current drilling aims to infill the spacing to ~120m.

·    The current drill holes have reduced the spacing within the Ultimate Open Pit generated by AMC in April 2024 to ~100m.

·    Geological distribution is sufficient for inferred resources throughout the ultimate pit shell (from April 2024). Some parts have sufficient spacing to be classified as indicated resources.

·    Significant intercepts are reported for results from 2024 drilling using the following parameters:

·   

·    Sampling is taken for all intervals with sulphide mineralization.

·    Sampling adhered to lithological boundaries and additionally the hanging wall and footwall was sampled.

·    The ore body generally dips 30 to 40 to the SW. In some parts of the deposit the ore body dips steeper 80. These steeper areas of mineralization are interpreted to be the result of post mineralization deformation.

·    The ore body is cut by steep NE faults, these normal faults are interpreted to throw the lower ore body 20-40 m

·    After samples are cut and bagged, they are sealed with zip ties. Samples were taken by East Star's senior geologist to ALS Oskemen.

·    The samples remained sealed until handed over to the laboratory.

·    Samples in the laboratory follow ALS standard procedures to ensure sample security.
