VANCOUVER, BC, June 1, 2026 /CNW/ - Orla Mining Ltd. (TSX:OLA) (NYSE:ORLA) ("Orla" or the "Company") reports that an illegal work stoppage and blockade by its unionized workers is underway at the Camino Rojo Mine located in Zacatecas, Mexico. As a result, operations at the mine have been temporarily halted. All the equipment required to maintain the safety of the operation and the environment continues to be operated and monitored.

The work stoppage has not followed the procedures required under Mexican law, including the filing of a strike notice.

The work stoppage and blockade arose in connection with negotiations regarding two separate payments: a worker productivity bonus and a profit-sharing entitlement, known in Mexico as a PTU or Participación de los Trabajadores en las Utilidades. The Company had previously calculated and paid workers the maximum profit-sharing entitlement stipulated under Mexican law. While the Company and representatives of the workers' union negotiated the productivity bonus, members of the unionized workforce objected to the amount paid under the profit-sharing entitlement and initiated the illegal stoppage and blockade.

The Company is engaged in dialogue with the union leadership in an open and constructive manner to have employees return to work and for operations to safely resume as soon as possible. A meeting of representatives of the Company and the union with the Department of Federal Labour Conciliation is scheduled for Tuesday, June 2, 2026. Given the current duration of the production interruption and the nature of heap leach processing, the Company will assess any potential impact of the work stoppage on its full-year production guidance for Camino Rojo and will provide an update in due course.
