Orla Mining Reports Second Quarter 2025 Financial Results

VANCOUVER, BC, Aug. 11, 2025 /CNW/ - Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) ("Orla" or the "Company") today announces the results for the second quarter ended June 30, 2025.

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

• 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 ("AISC") 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

_{¹ Orla completed the acquisition of Musselwhite on February 28, 2025. Operational figures (excluding cash cost and AISC) are provided from March 1, 2025 onwards.
² Non-GAAP measure. Refer to the "Non-GAAP Measures" section of this news release.
³ Cash cost and AISC on a year-to-date basis for 2025 include the impact of the Musselwhite Mine as of April 1, 2025 onwards. Refer to "Non-GAAP Measures" for further discussion.}

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.

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 (BLM) in accordance with the National Environmental Policy Act (NEPA) 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.

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.}

About Orla Mining Ltd.

Orla's corporate strategy is to acquire, develop, and operate mineral properties where the Company's expertise can substantially increase stakeholder value. The Company has three material projects, consisting of two operating mines and one development project, all 100% owned by the Company: (1) Camino Rojo, in Zacatecas State, Mexico, an operating gold and silver open-pit and heap leach mine. The property covers over 139,000 hectares which contains a large oxide and sulphide mineral resource, (2) Musselwhite Mine, in Northwestern Ontario, Canada, an underground gold mine that has been in operation for over 25 years and produced over 6 million ounces of gold, with a long history of resource growth and conversion, and (3) South Railroad, in Nevada, United States, a feasibility-stage, open pit, heap leach gold project located on the Carlin trend in Nevada. The technical reports for the Company's material projects are available on Orla's website at www.orlamining.com, and on SEDAR+ and EDGAR under the Company's profile at www.sedarplus.ca and www.sec.gov, respectively.

We have included herein certain performance measures ("non-GAAP measures") which are not specified, defined, or determined under generally accepted accounting principles ("GAAP").  These non-GAAP measures are common performance measures in the gold mining industry, but because they do not have any mandated standardized definitions, they may not be comparable to similar measures presented by other issuers.  Accordingly, we use such measures to provide additional information, and you should not consider them in isolation or as a substitute for measures of performance prepared in accordance with GAAP.  In this section, all currency figures in tables are in thousands, except per-share and per-ounce amounts.

AVERAGE REALIZED GOLD PRICE

Average realized gold price per ounce sold is calculated by dividing gold sales proceeds received by the Company for the relevant period by the ounces of gold sold.

NET CASH (NET DEBT)

Net cash (net debt) is calculated as cash and cash equivalents and short-term investments less total debt adjusted for unamortized deferred financing charges at the end of the reporting period. 

ADJUSTED EARNINGS AND ADJUSTED EARNINGS PER SHARE

Adjusted earnings excludes unrealized foreign exchange, changes in fair values of financial instruments, impairments and reversals due to net realizable values, restructuring and severance, and other items which are significant but not reflective of the underlying operational performance of the Company.

Companies may choose to expense or capitalize costs incurred while a project is in the exploration and evaluation phase.  Our accounting policy is to expense these exploration costs.  To assist readers in comparing against those companies which capitalize their exploration costs, we note that included within Orla's net income for each period are exploration costs which were expensed, as follows:

FREE CASH FLOW

Free Cash Flow is calculated as the sum of cash flow from operating activities and cash flow from investing activities, excluding certain unusual transactions.  

Included within the figures for Q1 2025 are $798,504,000 for the acquisition of Musselwhite Mine.

CASH COST AND ALL-IN SUSTAINING COST

Cash cost per ounce is calculated by dividing the sum of operating costs and royalty costs, net of by-product silver credits, by ounces of gold sold.  All-in Sustaining Cost is intended to reflect all the expenditures that are required to produce an ounce of gold from operations.  While there is no standardized meaning of the measure across the industry, the Company's definition conforms to the all-in sustaining cost definition as set out by the World Gold Council in its guidance. 

The Musselwhite Mine was acquired on February 28, 2025, and accounting rules require metal inventory on hand at acquisition date (February 28, 2025) to be valued on the books at fair value rather than historical cost which is ordinarily the case. Accordingly, Orla management concluded it would not be meaningful to readers to present cash costs and AISC for Musselwhite Mine for the one-month period ended March 31, 2025.  The tables below exclude the costs of, and gold sales of, Musselwhite Mine for the period March 1 to March 31, 2025. Consequently, the year-to-date numbers presented in the table below have been adjusted to reflect Musselwhite's contribution as of April 1, 2025.

(note, the tables above exclude costs and gold sales for Musselwhite Mine for the period March 1 to March 31, 2025)

EXPLORATION AND PROJECT DEVELOPMENT COSTS

Exploration and project development costs are calculated as the sum of costs related to exploration and to project development.  Some of these costs have been expensed, while some of these have been capitalized, in accordance with our accounting policies.

Cautionary Note to U.S. Readers

This news release has been prepared in accordance with Canadian standards for the reporting of mineral resource and mineral reserve estimates, which differ from the previous and current standards of the United States securities laws. In particular, and without limiting the generality of the foregoing, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "inferred mineral resources", "indicated mineral resources", "measured mineral resources" and "mineral resources" used or referenced in this news release are Canadian mineral disclosure terms as defined in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Definition Standards").

For United States reporting purposes, the United States Securities and Exchange Commission ("SEC") has adopted amendments to its disclosure rules (the "SEC Modernization Rules") to modernize the mining property disclosure requirements for issuers whose securities are registered with the SEC under the Securities Exchange Act of 1934, as amended. The SEC Modernization Rules more closely align the SEC's disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including NI 43-101, and replace the historical property disclosure requirements for mining registrants that were included in Industry Guide 7 under the U.S. Securities Act. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multijurisdictional disclosure system (MJDS), the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and provides disclosure under NI 43-101 and the CIM Definition Standards. Accordingly, mineral reserve and mineral resource information contained in this news release may not be comparable to similar information disclosed by United States companies.

As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be "substantially similar" to the corresponding CIM Definition Standards that are required under NI 43-101. While the above terms are "substantially similar" to CIM Definition Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. There is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules. Accordingly, information contained in this news release may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

Appendix: Camino Rojo Underground Mineral Resource Estimate

Table 1: Camino Rojo Underground Mineral Resource Estimate:

Mineral Resources Notes:

1. CIM (2014) definitions were followed for Mineral Resources. The mineral resource estimate for Camino Rojo has an effective date of March 31, 2025.
2. The Qualified Person responsible for the mineral resource estimate is Marie-Christine Gosselin, P.Geo., Senior Resource Geologist of SLR Consulting (Canada) Ltd.
3. Mineral resources are estimated using a long-term price of US$2,300 /oz gold, US$1.25 /lb zinc and US$29 /oz silver and the following smelter terms: for oxide 99.9% payable Au and 98% payable Ag, and for sulphide 95% payable Au, 90% payable Ag and 95% payable Zn. Offsite costs (refining, transport and insurance) of US$145 /wmt transportation and US$230 /dmt treatment; a 2.5% NSR royalty.
4. Metallurgical recoveries vary according to geometallurgical domains from heap leach, CIL, and flotation CIL with POX and are either constant or formula based. Heap leach recoveries range from 40% to 70% for gold and from 11% to 34% for silver. For CIL and CIL with POX, gold and silver recoveries are calculated using grade dependent formulae. The underground CIL mean recovery is 92% for gold and 36% for silver. The underground CIL with POX mean recovery is 85% for gold and 41% for silver. Zinc recovery by flotation is 80%.
5. Mineral Resources are estimated in underground resource panels using NSR cut-off grades of 59.02 US$/t for leach material, 68.73 US$/t for CIL material, and 76.23 US$/t for CIL w/POX material. Underground resource panels have a minimum width of 2m.
6. The NSR for heap leach material is calculated with the following formula: NSR ($/t) = US$71.98 x Au recovery x Au grade + US$0.84 x Ag recovery x Ag grade (g/t). The NSR for CIL material is calculated with the following formula: NSR ($/t) = US$68.34 x Au recovery x Au grade (g/t) + US$0.73 x Ag recovery x Ag grade (g/t). The NSR for CIL w/POX material is calculated with the following formula: NSR ($/t) = US$68.34 x Au recovery x Au grade (g/t) + US$0.73 x Ag recovery x Ag grade (g/T) + US$0.00146 x Zn recovery x Zn grade (ppm).
7. The gold equivalent (AuEq) for heap leach material is calculated with the following formula: Au grade (g/t) + (US$0.84 x Ag recovery x Ag grade (g/t)) /(US$71.98 x Au recovery). The AuEq for CIL material is calculated with the following formula: Au grade (g/t) + (US$0.73 x Ag recovery x Ag grade (g/t)) / (US$68.34 x Au recovery). The AuEq for CIL w/POX material is calculated with the following formula: Au grade (g/t) + (US$0.73 x Ag recovery x Ag grade (g/t)) / (US$68.34 x Au recovery) + (US$0.00146 x Zn recovery x Zn grade (ppm)) / (US$68.34 x Au recovery).
8. Numbers may not add due to rounding.

The Mineral Resource estimate includes Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

The following factors, among others, could affect the mineral resource estimate: commodity price and exchange rate assumptions, pit slope angles, assumptions used in generating the resource pit shell and underground resource panels, including metal recoveries, and mining and process cost assumptions.
