DGAP-News: Polyus Finance Plc / Key word(s): Drilling Result Press Release 24 January 2019 PJSC Polyus Sukhoi Log Mineral Resources Update PJSC Polyus (LSE, MOEX - PLZL) ("Polyus", the "Company") provides an update on Mineral Resources estimate for Sukhoi Log and reports a maiden Indicated Mineral Resource estimate completed by AMC Consultants Pty Ltd ("AMC") in compliance with JORC Code 2012. The estimated Mineral Resources at Sukhoi Log stand at 962 mt, with an average grade of 2.1 g/t Au and containing 63 moz of gold as at 30 October 2018. The estimate is a nine per cent increase compared to the previous estimate of 58 moz of gold as at 31 January 2017. AMC has also upgraded 28 moz of Inferred Mineral Resources to Indicated Mineral Resource. The 2018 Mineral Resource estimate is based on data from the verification drilling programme available at 14 September 2018 used in conjunction with historic drillhole data. The Company continues in-fill, deep levels, flanks and other drilling. The drilling campaign will continue until the end of 2019. Polyus plans to drill a total of 197,000 meters, including the approximately 135,000 meters drilled since October 2017. Ongoing assessment of the drilling campaign samples may result in further upgrade of the Mineral Resources estimate classification. As previously reported, the Company is proceeding with studies to enable estimation by AMC in 2020 of an Ore Reserve estimate based on Indicated Mineral Resources in the 2018 estimate and estimates resulting from the 2019 drilling campaign. Pavel Grachev, Chief Executive Officer of PJSC Polyus, commented: "The continued exploration success we are achieving at Sukhoi Log is reaffirming its status of one of the best undeveloped deposits globally and a cornerstone of Polyus long-term development strategy. We plan to proceed with the drilling campaign till the end of 2019 to further enhance definition of the ore body structure, and expect to deliver a maiden Ore Reserve estimate for Sukhoi Log in 2020."

Historic Data The historic data available for the resources estimation comprises:
In 2017, relying entirely on historic drillhole data, AMC estimated Mineral Resources for Sukhoi Log which it classified as Inferred Mineral Resources. At that time, the classification predominantly reflected uncertainty about the quality of the historic data. The Inferred Mineral Resources estimate stood at 887 mt with an average grade of 2.0 g/t Au and containing 58 moz of gold as at 31 January 2017. Verification Drilling An exploration and mining licence was granted on 21 February 2017. Polyus has carried out extensive drilling since October 2017 to verify historic data to determine whether the historic drilling could be used to form a Mineral Resource estimate that could be classified as Indicated Resource:
Geological logging, sampling and assaying of verification drillholes follow current industry best practice. Verification drilling is supported by an industry-standard quality control and quality assurance protocol. Mineral Resource estimate Geological logging of both verification and historic drilling was reviewed to ascertain a usable geological basis for determining a domain boundary for the historic data (both hangingwall and footwall positions) used in the Mineral Resource estimate. Based on that review, AMC concluded that:
Within the geological framework, the mineralized volume has been estimated using a probability model. Gold grade has been estimated using ordinary kriging. The estimated Mineral Resources in the verification area have been classified as Indicated Mineral Resources based on both historic and verification drillhole data and constrained by hangingwall and footwall surfaces. Parts of the Mineral Resource estimate outside the verification area have been classified as Inferred Mineral Resources because their estimation relies entirely on historic data and the hangingwall and footwall surfaces cannot be interpreted with sufficient confidence. The footwall zone has been classified as Inferred Mineral Resources since it is based purely on wide-spaced verification drilling. AMC's estimate of Sukhoi Log's Mineral Resources at 30 October 2018 is 962 mt with an average grade of 2.1 g/t Au and containing 63 moz of gold. The JORC Code Table 1 supporting the Sukhoi Log 2018 Mineral Resource estimate is listed in the Addendum following this statement. Competent persons The Mineral Resources estimates are classified and reported according to the JORC Code reporting requirements. As part of the verification drilling programme. AMC's Principal Geologist Dean Carville visited the Sukhoi Log site in February and August 2018 to examine the following:
