(Uranium One Group) // boytsovav@u1h.com WORLD URANIUM INDUSTRY: STATUS, DEVELOPMENT PROSPECTS, CHALLENGES According to the basic scenario of the development of the world nuclear power industry, uranium mining by 2030 should increase by 1,5 times. Uranium production from existing mines will decrease, while planned new mines will only compensate closed mines capacities. Additional 30 ktU must be produced annually in 2035 from new prospective mines. Despite depressed market, uranium production continued to grow steadily and reached 62ktU in 2016 – a historical maximum since 1988. In Situ Leach became the main uranium mining method since 2010. The total uranium resource base is more than sufficient to ensure the long-term needs of nuclear industry. At the same time, the great share of resources belongs to high cost categories and after 2020 uranium producers may face the shortage of low cost resources. In 2010 Rosatom has acquired a Canadian public company Uranium One in order to secure long term uranium supply for Russian nuclear fuel cycle chain. It has consolidated on its basis high quality uranium assets in Kazakhstan and in other countries. Uranium One has increased annual production almost 5 times during the last 7 years and became a fourth global U producer. Known resources and planned mining capacities secure further sustainable U production grown at favorable market conditions. Keywords: Uranium, mining, production, exploration, resources, resource base, uranium market, price, supply, demand, Rosatom, Uranium One, Kazatomprom. Р. 4-8 |

Within the framework of the problem, promising provinces, regions and specific exploration facilities are presented, which require forecast-thematic, prognostic-mineragenic and prospecting works, respectively. The modern effective geological, geophysical and geochemical methods for prospecting and assessing uranium deposits are covered, on the basis of which for potentially ore-bearing territories it is possible to form rational prognostic-search complexes with preliminary approbation of them at reference facilities. Keywords: mineral resources base, uranium, exploration targets, exploration technique, prospecting complexes. Р. 8-22 |

Particular attention is paid to the comparative characteristics of the gold-uranium mineral deposits with foreign counterparts (occurrences of the Rompas Group, Finland). The area allocation for prospecting works aimed at identifying gold mineral deposits of two ore formations: gold-uranium in albite-carbonate metasomatites and gold-sulfide-quartz is proved; recommendations for further work are given. Keywords: gold, uranium, albite-carbonate metasomatites, occurrences of the Rompas Group. Р. 31-36 |

Relevant indicators and methodical aspect of the parameter investigation are considered. The main attention is devoted to reconstruction of processes of solution migration along fault-fracture zones, which form complex geological and physical objects.

(Atomredmetzoloto) // shumilin.zbk@gmail.com FIELDS SUCH AS «DISAGREEMENT»: MODERN GENETIC SKYE MODEL AND THE PROBLEM OF SEARCH IN RUSSIA The new genetic model offered for the deposits of very rich ores of Atadasca basin (Canada) is considered. Position of the accessory source of uranium is criticized. Expected that uranium was passed to basin as dissolved faze, which was enriched of uranium by primary concentrations in rocks. From this conception, Canadian deposits are compared with the similar objects of Africa and Russia. Attention applies on distinctions in the structures of sediments of basins and differences of water dynamic. Perspectives of discovers of Canadian types of deposits in Russia are analysed. Keywords: uranium, the type of disagreement, genetic model. Р. 42-47 |
