The acquisition transaction previously announced February 9, 2021, continues in accordance with the timeline outlined in the press release dated March 10, 2021.

Cautionary Note Regarding Concessions
Thirty-two of the Company's concession are currently subject to Administrative and Judicial processes (together, the "Processes") in Peru to overturn resolutions issued by the Institute of Geology Mining and Metallurgy ("INGEMMET") and the Mining Council of the Ministry of Energy and Mines ("MINEM") in February 2019 and July 2019, respectively, which declared Macusani's title to the 32 of the concessions invalid due to alleged late receipt of the annual validity payment. The Company was successful in obtaining injunctive relief for the 32 concessions in a Court in Lima. The grant of the Precautionary Measure (Medida Cautelar) restores the title, rights and validity of those 32 concessions to Macusani within INGEMMET until a final decision is obtained in at the last stage of the judicial process. A date for a decision in the judiciary has not yet been set. If the Company does not obtain a successful resolution of Processes, Macusani's title to the concessions could be revoked.
