^{(All amounts expressed in U.S. dollars unless otherwise stated)}

Second Quarter 2025 Summary

• Record quarterly gold production of 77,811 ounces and total quarterly gold sold of 78,911 ounces (pre-released).
• Second quarter all-in sustaining cost¹ was $1,421 per ounce of gold sold. Year to date AISC was $1,260 per ounce of gold sold.
• Net income for the second quarter was $48.2 million or $0.15 per share
• Adjusted earnings¹ for the second quarter were $64.2 million or $0.20 per share.
• Cash flow from operating activities before changes in non-cash working capital during the second quarter was $102.7 million.
• Exploration and project expenditure¹ was $32.3 million during the quarter, of which $22.9 million was capitalized and $9.4 million was expensed.
• The Company experienced a pit wall event at Camino Rojo on July 23^rd. The mine has started the work on the action plan, including a 50–80 metre pushback of the north wall with a redesigned slope and continuous monitoring. As a result of the operational pause and mining resequencing at Camino Rojo, Orla updated annual consolidated guidance to 265,000 to 285,000 ounces of gold production and AISC of $1,350 to $1,550 per ounces of gold produced.
• The Company ended the period with $215.4 million in cash and $420.0 million in debt after paying $30.0 million towards its revolving credit facility during the quarter.

“The second quarter marked another record production period for Orla, supported by strong contributions from Musselwhite. However, the pit wall event at Camino Rojo on July 23rd was an operational setback. Thanks to proactive geotechnical monitoring systems, no injuries occurred, and no equipment was damaged. While the temporary suspension of in-pit operations poses a short-term challenge for what has otherwise been a consistently strong-performing mine, the benefits of Orla’s diversified production base are clear.”

– Jason Simpson, President and Chief Executive Officer of Orla

Second Quarter 2025 Consolidated Summary

Gold produced during the quarter totaled 77,811 ounces, with contributions from the Camino Rojo Oxide Mine and the Musselwhite Mine. This period represented the first full quarter of contribution from Musselwhite, resulting in a quarterly record for production for the Company.

Gold sold during the quarter totalled 78,911 ounces, also a quarterly record. Consolidated cash costs and AISC totaled $1,065 and $1,421 per ounce of gold sold, respectively.

Camino Rojo Operations Summary

The Camino Rojo Oxide Gold Mine produced 25,145 ounces of gold in the second quarter of 2025, in-line with plan.

During the quarter, Camino Rojo mined nearly 2.0 million tonnes of ore and 2.6 million tonnes of waste, for an implied strip ratio of 1.33. A total of 1.7 million tonnes of ore were stacked at an average grade of 0.71 g/t gold equating to an average daily stacking rate of approximately 18.5 thousand tonnes. In addition, 0.9 million tonnes of low-grade ore were rehandled and placed on the leach pad, at an average grade of 0.32 g/t gold. In total, 2.6 million tonnes of ore at an average grade of 0.57 g/t gold were placed on the heap leach pad during the quarter.

Gold sold during the second quarter 2025 totaled 26,591 ounces and sustaining capital during the second quarter of 2025 totaled $0.5 million.

On July 23rd, Camino Rojo experienced an uncontrolled material movement on the north wall, resulting in no injuries or equipment damage. Work has started on the action plan, including a 50–80 metre pushback of the north wall with a redesigned slope and continuous monitoring. Approximately 9.0 million tonnes of predominantly oxidized material (strip ratio 1:0.9, average grade 0.74 g/t Au) is planned to be removed and stacked on the heap leach. No material was lost or sterilized; the update to 2025 guidance reflects a deferral of production based on grade and recovery mix. See “2025 Guidance Update” below for details.

Musselwhite

During the quarter, Musselwhite mined 303,000 tonnes of ore and milled 295,000 tonnes at a mill head grade of 5.52 g/t gold. Gold recovery rates of 96.5% resulted in gold production of 52,666 ounces. Gold sold during the quarter was 52,318 ounces.

Lateral development metres in the quarter totalled 2,746 metres.  Lateral development is to access mining horizons for existing reserves and to provide additional drill platforms to support the underground exploration drill program to grow reserves, resources, and mineral inventories.

Sustaining capex was $18.4 millions, mostly driven by underground development and PQ Deep Extension.

Project and Exploration Summary

The key project highlight of the quarter was the release of the initial underground Mineral Resource estimate at Camino Rojo on June 5, 2025. The Mineral Resource estimate will support future technical studies, engineering evaluations, and permitting preparations as the project advances.

During the quarter, exploration focused on drilling activities at Camino Rojo in Mexico, the South Carlin Complex (including the South Railroad Project) in Nevada, and Musselwhite in Canada. For the second quarter, a total of 23,248 metres were drilled, with 7,575 metres in Mexico, 4,686 metres in Nevada and 10,987 metres at Musslewhite. Project development activities during the period focused on advancing permitting efforts for the South Railroad Project in Nevada and progressing the potential underground development at Camino Rojo.

Camino Rojo, Mexico:

During the quarter, the Company released an initial underground Mineral Resource estimate for the Camino Rojo deposit, incorporating mineralization hosted in the Camino Rojo Sulphides and extending into the underlying Zone 22. As a reminder Zone 22 represents the vertical and down plunge continuation of the Camino Rojo sulphide mineralization. A supporting technical report was released in July. Summary highlights of the initial resource:

• Zone 22 accounts for only 7% (0.29 Moz AuEq) of the current underground Indicated Mineral Resource and 19% (0.08 Moz AuEq) of the current underground Inferred Mineral Resource. Drilling is ongoing and 2025 results will inform future updates.
• Recovery model supported by ongoing metallurgical work and the mineral resource is divided into three spatially distinct zones, each with specific processing options for the Caracol-hosted mineralization:
  • Heap leaching (3%),
  • Flotation by cyanidation (CIL) (25%),
  • Flotation followed by pressure oxidation (“POX”) as a pre-treatment prior to cyanidation (CIL with POX) (72%).
  • Initial metallurgical testing indicates that material from Zone 22 is amenable to both cyanide leaching and flotation.
• Development strategy focuses on advancing the underground resource through:
  • Continued drilling
  • Exploration drift design
  • Flowsheet optimization
  • Metallurgical and engineering studies
  • Permitting activities

The Company continued the infill drill campaign at Zone 22, the extension of the Camino Rojo Sulphides. The 15,000-metre drill program was completed in late July 2025. An additional 5,000 metres are planned in 2025 at Zone 22 for infill and expansion along the down-plunge. Results from these drill programs are expected to enhance the Zone 22 resource, which was included in the recently released Camino Rojo Mineral Resource update, as discussed above. A drill campaign to test regional targets started in mid-April, with 1,722 metres drilled in the second quarter. Please see Company’s news release dated August 7,  2025, for additional information (Orla Mining Reports New Drill Results from Zone 22 at Camino Rojo, Mexico – High grade intersections outside current resource panels enhances potential).

South Railroad Project & South Carlin Complex, Nevada:

The South Railroad Project is currently advancing under the guidance of the US Bureau of Land Management in accordance with the National Environmental Policy Act for permitting.

Orla continues to engage with local, state and federal stakeholders to sustain momentum in the permitting process. The Notice of Intent (NOI) is expected to be published in the coming weeks (Q3) with the Company targeting a Record of Decision (final permitting decision) approximately 12 months thereafter. Following this approval, construction on the South Railroad Project would commence, with first gold production targeted for 2028.

Orla’s 2025 exploration program at the South Carlin Complex is focused on increasing resources at Dark Star, Pinion and satellite deposits, as well as discovering new zones of mineralization. Drilling activities resumed in May at the new Spike target – located south of Pod-Sweet Hollow, as well as at the North Bullion target area. In June, the Dark Star and Bowl drill programs were initiated. Exploration activities are expected to continue through the end of 2025.

Musselwhite, Ontario:

At Musselwhite, the exploration objective is to define a critical mass of additional reserves and resources to support expansion of the operation and significantly extend the mine life.  In the second quarter, underground exploration drilling progressed with three rigs, completing 7,413 metres. The deep directional surface program aimed at confirming the down-plunge extension of the mine trend began in late May with one drill rig. By early June, three rigs were operational, collectively completing 2,757 metres of drilling in the second quarter. The deep directional target zones are expected to be reached in the third quarter. Additionally, the near-mine surface program focused on identifying shallow mineralization as potential open pit mill feed started in June, with 817 metres drilled in the quarter. All exploration drilling programs will continue through the year.

2025 Guidance Update

Since the pit wall event on July 23, Camino Rojo has continued to crush and stack stockpiled material at a rate of approximately 20,000 tonnes per day (in addition to 20,000 tonnes per day being truck stacked), to mitigate the short-term impact on production. Based on the current action plan and Camino Rojo’s updated pit sequencing, Orla’s annual production, cash costs, and AISC guidance has been updated and is shown below.

¹ _{Cash cost and AISC include 9 months of production and costs from Musselwhite, and full year from Camino Rojo and Corporate G&A (inclusive of share-based compensation). Cash costs and AISC are non-GAAP measures. Please refer to the Non-GAAP section of this news release for further detail.}
