Cautionary Note Regarding Plateau Concessions

Thirty-two of Plateau's 151 concession are currently subject to Administrative and Judicial processes (together, the "Processes") in Peru to overturn resolutions issued by INGEMMET and the Mining Council of MINEM in February 2019 and July 2019, respectively, which declared Macusani's title to the 32 of the concessions invalid due to late receipt of the annual validity payment. Plateau successfully applied for injunctive relief on 32 concessions in a Court in Lima, Peru and the grant of the Precautionary Measures (Medida Cautelar) has restored the title, rights and validity of those 32 concessions to Macusani until a final decision is obtained in at the last stage of the judicial process. If Plateau does not obtain a successful resolution of Processes, Macusani's title to the concessions could be revoked.
