Current status of mineral resources reporting in the Kyrgyz Republic

The process of systematizing mineral reserves in the Kyrgyz Republic began in 1927, when the State Reserves Commission (GKZ) of the USSR was created, and was associated with industrialization under the conditions of state ownership of subsoil and means of production, “... to give uniformity and authority to all reserves figures ..." The main function of the State Reserves Committee was to protect the state treasury from unjustified expenses for the construction and reconstruction of mines that were not provided with reserves.

In the field of examination of reserves explored in the subsoil, the USSR was ahead of the whole world, which began development only after financial scams in the 1960s and only by the end of the 1980s. adopted CRIRSCO standards (JORC, etc.).

The Joint Resources Committee (JORC) first published the Australasian Minerals Public Reporting Code in 1989, which was formally included in the Australian and New Zealand stock exchange listing procedures for investment decisions and shareholder behavior. as part of a game on the stock exchange.
The practical usefulness and effectiveness of the JORC Code are ensured by compliance with three main conditions: transparency of information, relevance to the consumer and the involvement of highly qualified specialists in the preparation of reports.

That is, the basis of the contradiction between the State Reserves Committee and CRIRSCO is the attitude towards mineral reserves either as a source of benefits for socialist construction or as a commodity in the form of an integral element of the share capital of mining companies. But at the same time, the content of the examination of reserves in any format is close to each other and their basis is the provision of reliable reserves of minerals.

The UN Framework Classification is a universal system applied to energy and mineral reserves and resources located above or below the earth based on three fundamental criteria: Economic and social viability of the project (E), Status and feasibility of the development project (F), Geological knowledge (G).

There are examples of real cases of application of framework documents for the harmonization of CRIRSCO, State Reserves Committee of the Kyrgyz Republic and UNFC standards.
Since 2013, the Kyrgyz Mining Association has been working on the practical application of international reporting standards in the Kyrgyz Republic. In particular, in 2012 the Association developed a Strategy for the Development of the Mining Industry for 2013–2035. for the Government of the Kyrgyz Republic.

In 2017, a tripartite memorandum was signed between the State Committee for Industry, Energy and Subsoil Use of the Kyrgyz Republic, the CRIRSCO Council and the Kyrgyz Mining Association on the inclusion of the Kyrgyz Republic in the CRIRSCO family of countries. Within the framework of this memorandum, the Kyrgyz Society of Subsoil Experts was created as an independent National Institute of Competent Persons. By Order of the Ministry of Natural Resources, Ecology and Technical Supervision of the Kyrgyz Republic No. 15-p dated February 2, 2024, the Kyrgyz Republic Standard (KyrRC) was adopted as a reporting and calculation system inventory based on the CRIRSCO template.

Currently, the Kyrgyz Society of Subsoil Experts with the support of the Ministry of Natural Resources, Ecology and Technical Supervision of the Kyrgyz Republic, the State Enterprise Kyrgyzgeology on the basis of the Kyrgyz Mining and Metallurgical Institute named after. Academician U. Asanaliev is working on training, certification and accreditation of independent highly qualified specialists as Candidates, Experts and Competent Persons.

Innovative proposal for the production of rare earth metals

The report will provide information on the resumption of mining and geological activity within the Aktyuz ore field, which has no analogues in the concentration of yttrium-earth lanthanides, despite their low content (up to 2.5%). Its areas are poorly eroded and not deeply explored, which opens up prospects for their study, the discovery of “blind” productive bodies and the increase in reserves of both profiling rare earth mineralization and accompanying polymetallic (Pb, Zn, Bi, Mo, Ag, etc.) with scattered rare and toxic microcomponents (Cd, In, possibly Re, etc.).

Mineral resource base of rare earth elements in Kyrgyzstan

A. The balance of balance reserves at the Kuttusai-2 deposit in category B+C1+C2 is: ore - 20.2 million tons, the amount of rare earths - 51.5 thousand tons, in addition to rare earth metals, the ore contains molybdenum, bismuth, lead, beryllium , silver, etc. In the future, additional geological exploration work in the southwestern direction will allow increasing the balance reserves of ore volumes of the deposit to 30 million tons or more, and the volumes of rare earth metals can reach up to 75 thousand tons

B. The deposit of tantalum-niobium-rare earth raw materials in the alkaline carbonatite complex with alteration zones in the host rocks Sarysai is considered as a new, potentially promising source of rare earth metals in Kyrgyzstan. The average contents of rare metals are: sum of rare earth metal oxides - 2.4 kg/t, including 600 g/t yttrium oxide; Nb2O5 - 1.5 kg/t and Ta2O5 - 110 g/t. The ratio of the sum of rare earth metals to yttrium is 4:1, niobium to tantalum is 10:1. The REM composition is dominated by Ce (34%) and La (20.72%) with a high proportion of Y (19.19%), as well as Nd (12.73%) and Pr (3.51%). Also noteworthy are the increased contents of the most deficient Dy (2.27%), Sm (1.95%), Gd (1.49%), Er (1.52%), Yb (1.29%) and others yttrium-earth lanthanides of the medium-heavy group.

B. The tailings dumps are of independent interest (four are in the area of ​​the Ak-Tyuz village, the fifth is the Bordunsky tailings dump, not far from the village of Orlovka). In addition to rare earth elements, they contain heavy metals (lead, molybdenum, cadmium, zinc, etc.), and are characterized by increased radioactivity due to the presence of thorium-containing elements. According to preliminary estimates. The volume of three tailings dumps is 1,790 thousand m3. they contain up to 5750 tons of REE, including the light group - 52% (about 3000 tons), the medium group - 15% (862.4 tons) and the heavy group 5% (287.5 tons).
