Highlights: · Total of 4,947m of diamond core drilling across both licences comprising: o 17 boreholes totalling 3,088m on the Novoe, Southern Shabdar and Eshkilitau II targets on the Apmintas Licence o 19 boreholes totalling 1,860m on the Alatagyl target on the Dalny licence · Programme was designed to test mineralisation along strike and down dip from previous intersections from both East Star's reverse circulation drilling programme in 2021 and historical drilling at Southern Shabdar and Alatagyl · Visual inspection of core shows promising signs of potentially gold bearing mineralisation across all targets · Company intends to release assay results on a target-by-target basis for completeness Alex Walker, East Star CEO, commented: "We are pleased with the pace and quality of the drill programme and encouraged by visual indicators in core samples. By doing oriented diamond core drilling, our team can get a strong understanding of the geometry of the structures controlling the mineralisation. This will form the basis for the design of future work programmes and assist with targeting additional areas on the huge and prospective Apmintas Licence. Shallow recordings of sulphides on the Alatagyl target also demonstrate a good indication of potentially gold bearing mineralisation. Core is being logged, cut, and weighed, and some are undergoing density measurements and XRF analysis before being sent for assay preparation at the laboratory and then for assay. Lab turnaround times in Kazakhstan are variable and we intend to release assay results on a target-by-target basis to provide complete information to the market for each target. I am proud of our hardworking team and contractors for their execution of an efficient and safe programme. As we progress through the assay phase, we will continue to undertake the quality control to ensure an efficient process without compromising on quality."
