Development potential and investment attractiveness of PGM deposits (Monchegorsky ore district) are discussed. By the late 2020, the reserves of these deposits were approved based on results of a feasibility study review assessment in the State Reserve Commission and TsNIGRI approval. In current mineral market conditions (including high Pd price), the most attractive development projects are Vuruchuaivench deposit comprising 4 areas (Plast 300, Vuruchuaivench, Yuzhnosopchinsky and Arvarench), NittisKumuzhya-Travyanaya occurrence and Loipishnyun area. In terms of reserves, ore grades and proximity to processing plants, these potential mining projects are less expensive if developed concurrently. The paper presents recommendations for PGM deposit opening, development and mining using advanced mining equipment in open-pit and underground mining operations, ore conveying and processing plant tailings disposal to infill underground workings. Economic estimates were made supporting development viability of the above deposits within Monchegorsky ore district.
The paper highlights the location of precious metal deposits within the Russian Federation planned for federally funded exploration within Russia and its subjects during 2003-2024, as well as its funding dynamics; it also presents resources approved as a result of exploration and shows federally funded exploration areas for the near term. The conclusion is validated that supporting gold production at the current level in the mid- to long-term requires both enhancing prospecting activities and launching federally funded forecasting-mineragenetic works to localize promising areas containing potential resources.
The paper reviews the mining potential of opening and mining the Nittis-Kumuzhiya-Travyanaya (NKT) area
using conveyor transport, advanced equipment and filling the worked-out area to improve plant capacity and reduce environmental damage to the area. Analysis was performed for a prospective scheme of mining additionally explored areas of Donnaya orebody as well as feasible options of ascending excavation involving selective breaking of thin veins. Results of consolidated geological and economic estimate for NKT reserves to a depth of 500 m are presented. The authors believe that this technology is efficient due to reduced dilution and ore losses, improved miners’ work conditions, lower power and labor costs as well as higher ore throughput.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
