Polymetal International plc (POLY) Polymetal: Tomtor initial Ore Reserve estimate 19-Apr-2021 / 09:00 MSK Dissemination of a Regulatory Announcement, transmitted by EQS Group. The issuer is solely responsible for the content of this announcement.
Polymetal International plc Tomtor initial Ore Reserve estimate Polymetal announces that its associate ThreeArc Mining Ltd. (ThreeArc, in which Polymetal owns 9.1%) has completed an initial Ore Reserve estimate in accordance with the JORC Code (2012) for the Buranny area of the Tomtor niobium and rare-earth metals project (Tomtor). "Tomtor confirmed its scale and grade as one of the premier niobium and rare earths deposits globally", said Vitaly Nesis, Group CEO of Polymetal. "The project team will now focus on completion of a bankable feasibility study, paving the way for the investment decision. Permitting issues and a Covid-related slowdown in offshore engineering work remain the key challenges for the project". HIGHLIGHTS The initial Ore Reserve estimate as at 31 December 2019 comprises 11.4 Mt of ore available for open-pit mining at 6.0% Nb2O5[1]+14.5% REO[2] grade (including 2.8% of NdPr[3] oxides) containing 0.7 Mt of Nb2O5 and 1.7 Mt of REO which makes Tomtor one of the top-3 rare earths projects globally by reserves. The open pit mine will be operated in two roughly equal stages: Stage 1: 14 years of mining of niobium-rich ore with ore being stockpiled at the mine to provide feed sufficient for more than 40 years of processing at Krasnokamensk Hydrometallurgical Facility (KHF). The ore will be dried on site and transported via a sequence of ice roads, barges, ships and rail to KHF. Accelerating mining and stockpiling ore is considered to be the most practical approach given the project's location. Stage 2: the open pit will recommence after the ore stockpiled during Stage 1 has been fully processed to complete mining and stockpile ore for a further 27 years of processing. The Stage 2 feed will contain higher content of Rare Earth Elements (REE) and lower niobium grades. The KHF will be built near the town of Krasnokamensk located in South-Eastern Siberia close to the border with China being the location of Russia's largest uranium mine and associated processing and tailings infrastructure that is expected to be used to store the waste generated by the plant. The planned plant's throughput is 160 Ktpa of dry ore. The facility will produce niobium oxide which will be toll converted to ferroniobium, and a bulk REE carbonate concentrate which is currently planned to be toll treated to produce Ce&La oxides, NdPr oxides and a mixed medium-heavy rare earth carbonate. The bankable feasibility study of the project, including a number of downstream processing flowsheet improvements is currently in progress. The process has been slowed down due to Covid-related challenges. The completion of the feasibility study and basic engineering of the project will be contingent on the state approval of the sustainable waste management concept developed for the project and of the respective legislative changes. Mineral Resources (additional to Ore Reserves) amount to 1.5 Mt of ore with an average grade of 4.8% Nb2O5+15.2% REO grade representing 0.07 Mt of Nb2O5 and 0.2 Mt of REO. The Ore Reserve and Mineral Resource audit prepared by SRK Consulting (Russia) Ltd is the first independent audit of the Tomtor project.
ORE RESERVE AND MINERAL RESOURCE STATEMENT The Ore Reserve and Mineral Resource estimates are classified in accordance with the JORC Code (2012) as at 31 December 2019 using the following prices: US$ 23.9/kg of Nb2O5, US$ 53.5/kg of Pr6O11, US$ 48.5/kg of Nd2O3, US$ 20.80 / kg carbonate concentrate of medium and heavy rare earths (Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y) and at 7.8% Nb2O5 Equivalent cut-off grade. Any discrepancies in calculations are due to rounding. Tomtor Ore Reserve estimate
Tomtor Additional Mineral Resource estimate
ABOUT TOMTOR Tomtor is located in the north-west of Yakutia. It is one of the largest and highest grade rare earth elements (REE) projects globally and considered to be the highest grade development stage niobium (Nb) project in the world. The deposit was discovered in 1977 with initial statutory reserves approved in 1999. In 2013, ICT established ThreeArc Mining Ltd., a subsidiary of which purchased the Tomtor license subsequently. In March 2020, Polymetal acquired a 9.1% stake in ThreeArc for US$ 20 million. The proceeds were allocated to developing the Pre-Feasibility Study and preparing the initial Ore Reserve and Mineral Resource estimate. Competent persons The Ore Reserves estimate was compiled by David Pearce, who is employed full-time by SRK Consulting (Russia) Ltd, as a Principal Mining Consultant and Managing Director. Mr Pearce is a Fellow of the Australasian Institute of Mining and Metallurgy (AusIMM), and has sufficient experience relevant to the mining method and type of deposit under consideration, and to the engineering solutions proposed for developing the project, to qualify as a Competent Person as defined by the 2012 edition of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" (JORC Code). The Mineral Resource estimate was compiled by Robin Simpson, who is employed full-time by SRK Consulting (Russia) Ltd, as a Principal Consultant (Resource Geology). Mr Simpson is a Member of the Australian Institute of Geoscientists (AIG), and has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined by the 2012 edition of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" (JORC Code). The Competent Persons have given their consent to the inclusion in the report of the matters based on their information in the form and context in which it appears.
