Orla Mining Provides Initial Update on Pit Wall Event at Camino Rojo

VANCOUVER, BC, July 24, 2025 /CNW/ - Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) ("Orla" or the "Company") is providing an update on the recent pit wall event that occurred at its Camino Rojo Oxide Mine in Zacatecas, Mexico.

Pit Wall Event and Immediate Response

As reported on July 23, 2025, Camino Rojo experienced an uncontrolled material movement on the temporary north wall within the open pit. There were no injuries, nor was there any damage to equipment or the environment as a result of the event. Ramp access to the pit remains unaffected but open pit mining operations were temporarily suspended while the Company conducts the necessary geotechnical assessments to ensure safe remediation and the eventual resumption of mining activities. These assessments are being conducted by both the Company's internal team and third-party consultants. Completion of the initial geotechnical assessments is anticipated in the coming week, with the remediation plan to be outlined thereafter.

Material Volume and Recovery Outlook

Initial estimates indicate that approximately 390,000 tonnes of material moved from the north wall into the pit. It is expected that this material would be crushed and stacked on the heap leach pad in the medium term.

Ongoing Operations and Stockpile Management

Until in-pit mining operations resume, the Company will continue crushing and stacking run-of-mine ore and stockpile material on the heap leach pad. This strategy is expected to mitigate short-term impact on production. The crushing circuit, stacking, and process plant continue to operate.

The current stockpile is estimated at 2,243,000 tonnes with an average gold grade of 0.32 g/t. As a reminder, the Company's mining throughput capacity is approximately 50,000 to 60,000 tonnes per day, while its crushing throughput capacity is approximately 18,000 to 19,000 tonnes per day.

As the Company completes the necessary geotechnical assessments and refines the timeline for safe restart of mining operations, it will provide any updates to full-year production and cost guidance.
