Perkoa Mine Update
In addition, Trevali confirms media reports that a Perkoa Mine ("Perkoa") manager as well as a manager from Byrnecut, the Company's mining contractor, are being detained by authorities near the mine site in west-central Burkina Faso pending a trial on charges relating to the April 16, 2022 flooding event at Perkoa. Charges relating to this matter have also been filed against Nantou Mining ( Burkina Faso ) S.A. ("Nantou"), Trevali's 90% owned subsidiary and the operator of Perkoa.
