Company Also Files Camino Rojo Technical Report Including Underground PEA

VANCOUVER, BC, March 18, 2026 /CNW/ - Orla Mining Ltd. (TSX:OLA) (NYSE:ORLA) ("Orla" or the "Company") is pleased to announce receipt of the environmental impact assessment (Manifestación de Impacto Ambiental, "MIA") from Mexico's Secretariat of Environment and Natural Resources ("SEMARNAT") for its Camino Rojo Mine in Zacatecas, Mexico ("Camino Rojo"). With this approval, Orla now has all the permits necessary, including the Change of Land Use approval, to mine the remainder of the oxide open-pit, including the layback area, and to begin construction of an underground exploration decline to advance the Camino Rojo Underground Project. The Company has also filed an updated technical report for the property. The approval of the MIA is conditional upon Orla meeting certain customary conditions and standard requirements.

Full Authorization for Oxide Operations and Permits to Begin Underground Decline

The MIA grants the Company full authorization to complete the oxide open pit as outlined in the newly filed technical report. This includes the layback to the north and the east-west expansion, as well as extensions to the waste rock and low-grade stockpiles and associated infrastructure.

The MIA also authorizes the development of underground access works, including an exploration portal and decline, with work expected to begin as early as the second half of 2026. This will enable further resource definition and technical evaluation of the sulphide mineralization beneath the current open pit, a next step toward a potential transition to underground mining at Camino Rojo.

The Company's planned development sequence is as follows:

2026: Initiate the underground exploration decline.
2027: Begin an underground drilling program to support a Pre-Feasibility Study (PFS) and project permit submission.

There are no changes to the Company's 2026 production and cost guidance for Camino Rojo. Potential spending in 2026 related to the exploration decline would be additional to the current guidance.

Long-Term Commitment to Zacatecas

This MIA supports Orla's long-term commitment to investing in Zacatecas, Mexico, where the Company is focused on enhancing sustainable livelihoods, supporting local employment and entrepreneurship and delivering lasting economic benefits to surrounding communities. The Company recently outlined a Preliminary Economic Assessment ("PEA") for the underground project at Camino Rojo, which could double production and establish a multi-decade operating platform in Mexico. For further details, please refer to press release from February 19, 2026.
