Polymetal International plc (POLY)
  Polymetal International plcUpdated mineral resource estimate for Viksha deposit  Polymetal announces the updated Mineral Resource estimate in accordance with the JORC Code (2012) for Viksha PGM deposit. Resources at the property now stand at 5.7 Moz of palladium equivalent (PdEq). "We have confirmed Viksha's potential as a large open-pittable deposit. The goal is to complete the feasibility study and publish a reserve estimate in 1H 2021", said Vitaly Nesis, Group CEO of Polymetal. HIGHLIGHTS
Viksha Open Pit Mineral Resources estimate as at 5 September 2019
Notes: Mineral resources are provided in accordance with the JORC (2012) with a cut-off grade of palladium equivalent 0.5 g/t. The PdEq formula is: PdEq = Pd(g/t) + Pt(g/t)*0.43 + Au(g/t)*0.68+ Cu(%)*1.32, at Pd price of $1,500/oz, Pt price of $800/oz, Au price of 1,200/oz, Cu price of $6,000/t. ABOUT VIKSHA The Viksha is a PGM-copper deposit located in the Republic of Karelia (North-West Russia) approximately 450 km from St. Petersburg. The infrastructure in the area is well developed with easy access to grid power, paved roads, and railway. Polymetal's 100%-owned subsidiary holds a 20-year mining licence for a project area of 47 km2. GEOLOGY The property lies near the centre of the southern Karelian Craton which is situated within the Archaean granite-greenstone terrain, adjacent to the lower Proterozoic Onega trough. The Viksha deposit comprises of three adjacent areas within the north-west limb of the syncline structure: Viksha proper, Kenti, and Shargi. All of them contain platinum, palladium, gold and copper mineralisation within the Koikar sill gabbro-dolerites. The outcrop of reef-type mineralisation has been traced for over 20 km. Viksha mineralisation is localized within the stratified sill rocks at the boundary between the lower gabbro and the upper dolerite zones. The sill has a maximum thickness of approximately 235 m. The underlying dolomite sediments are 40-50 m thick. Mineralised zones are clearly stratified with gold and copper predominance in the upper part, and palladium in the lower part of the mineralisation. The platinum-palladium-gold-enriched layer lies approximately 45 m above the sediments. The reef thickness is 5-11 m. The near-surface reef-shaped mineralisation forms contiguous ore bodies of considerable width and is amenable to low-cost mechanised bulk open-pit mining. The shallow dip of mineralised zones enables selection of the acceptably low stripping ratios. MINERALOGY Mineralisation at the Viksha project is associated with titanium-magnetite, chalcopyrite, and bornite. The most abundant species are Pt arsenide and Pd tellurides. The PGM grain size is 5-9 μm; most PGM are locked or exposed/attached to Cu sulphides, Fe oxides/spinel/ilmenite, and silicate minerals. In contrast, the gold minerals, consisting dominantly of gold-bearing silver and electrum are coarser-grained. Favourable mineralogy (without nickel) enables conventional flotation process producing bulk copper-PGM sulfide concentrate that can be processed through either PGM refineries or copper smelters with PGM circuit.
