At the “Karlukovo” deposit, a recalculation and update of the limestone reserves for railway construction were carried out based on geological documentation, operational data, and modern surveying measurements. The reserve coordinates were corrected in accordance with environmental restrictions, and a new deposit outline was prepared. As a result, the geological blocks were redefined, the reserves were recalculated as of 2024, and a final geological report was prepared, serving as a basis for concession granting and future quarry development.
