Kislotoupor company took an active part in the discussion organized by the State Commission of Ukraine on Mineral Reserves (DKZ), dedicated to the implementation of the international CRIRSCO classification system (Committee for Mineral Reserves International Reporting Standards). This discussion became an important step on the path of Ukraine's integration into the global mineral raw materials market and bringing national reporting standards in line with international requirements. Company representatives delivered a presentation on the practical experience of applying various classification systems when evaluating deposits of white-burning clay and gypsum stone.

The CRIRSCO classification system is an international template for reporting on mineral resources and reserves that combines the best practices of leading mining jurisdictions worldwide. It establishes unified principles and standards by which companies must classify and publicly report on their mineral assets. The significance of this system lies in ensuring transparency, comparability, and reliability of information for investors, regulators, and other stakeholders. Without a recognized international classification, Ukrainian deposits remain opaque to foreign capital, significantly limiting opportunities for attracting investments.

A comparison of the Soviet and post-Soviet reserves classification system with international standards reveals significant differences in approaches and terminology. The Ukrainian system, inherited from the USSR, is based on categories A, B, C1, and C2, which are determined primarily by the degree of geological study of the deposit. In contrast, international codes -- JORC (Australia), NI 43-101 (Canada), NAEN (EU), and others -- classify resources and reserves by the level of geological confidence and economic viability of extraction. This fundamental difference complicates direct comparison of evaluation results and requires the development of special transition tables and methodologies.

The adaptation of Ukrainian standards to international codes NI 43-101, JORC, and NAEN is a strategic task on which the investment attractiveness of the domestic mining industry depends. Several approaches to harmonization were presented at the discussion: from complete replacement of the national system with an international one to creating a "transition bridge" that would allow parallel use of both systems. Experts agree that a phased approach is optimal -- first implementing CRIRSCO requirements for companies attracting foreign investments, and later -- for the entire industry.

Kislotoupor's role in the standards harmonization process is significant and multifaceted. Having experience working with both domestic and foreign investors, the company practically encounters the need to "translate" classification categories and prepare reports in different formats. Kislotoupor has already prepared technical reports on several deposits in accordance with NI 43-101 requirements, which made it possible to identify specific problems and propose practical solutions to overcome them. The company advocates for the creation of a national register of "competent persons" -- qualified geologists and mining engineers authorized to sign reports according to international standards, which is a mandatory CRIRSCO requirement.
