This ‘hero' took an airline to small claims court over cancelled flights and won — a victory for all travellers
A recent small claims court decision in Nova Scotia has called out a troubling and growing business practice among Canadian airlines. And consumers can thank Maritimer Jason Hennigar for this. Three years ago, Hennigar bought round-trip tickets to Florida from Halifax through Sunwing. Not once, but twice, the airline cancelled his scheduled flight for 'unanticipated business or operational constraints.' Baloney, a small claims adjudicator ruled in a decision issued in April. Hennigar just wanted to go on holiday — a trip to Disney he'd been planning since September 2022. ARTICLE CONTINUES BELOW After Sunwing cancelled his first flight and offered to rebook him on another plane — for $500 more — Hennigar agreed. When the airline cancelled the second flight and ignored his requests for the airline to get him on another plane, Hennigar felt he had no choice but to dig deeper into his pockets. Sunwing did not respond to the Star's emailed request for comment. The Advocate Is Sunwing responsible for reimbursing travellers after fire near resort? It says no — but a lawyer says not so fast Star advocate Diana Zlomislic takes a deep dive into Ontario's Travel Industry Act and wonders With his scheduled vacation just weeks away, he forked over $5,155.92 to Air Canada to get him to Florida — twice the amount he had already paid Sunwing. Hennigar read Canada's Air Passenger Protection Regulations, and knew that when an airline cancels a flight for reasons within its control, as Sunwing did, the law says a carrier must provide customers an alternate flight at no additional charge. But he also knew that time was running out and that he wasn't likely to convince a company that had stopped communicating with him that it was in the wrong. So he took his vacation and filed a legal action against Sunwing in a small claims court in Nova Scotia when he returned home. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW The case, which Hennigar won, shines a light on a 'highly problematic and growing business practice by airlines,' says Gabor Lukacs, president of Air Passenger Rights, a Canadian advocacy group. The group, Lukacs says, had no involvement in the case. The Nova Scotia man compiled a 16-tabbed binder of evidence for his Zoom hearing and represented himself. Lukacs, who has never met Hennigar, calls him a 'hero.' At the hearing, Sunwing's claims director testified that the second plane the airline cancelled — a 737 — was scheduled to carry 189 passengers from Halifax to Orlando in February 2023. In a public decision issued in April, small claims adjudicator August Richardson took Sunwing to task. Evidence presented in court, he wrote, shows the airline's business model 'was premised on selling enough tickets for a particular flight or destination to fill a plane.' If the airline failed to reach its target number of passengers by a specific date, it would cancel the flight. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW 'The best that could be said was that the defendant thought it would be too expensive to fulfil its obligation to the claimant to find an alternate flight at no additional cost,' Richardson wrote. 'But the fact that a contract proves more expensive than a contracting party thought it would be does not excuse that party from performance. A bad deal is still a deal.' Lukacs loves that last line and repeats it several times during our interview. 'It's the first time this practice has been called out,' he says. 'When an airline says your only option is to cancel or pay more, that's not acceptable. That's illegal.' The Advocate Air Canada placed this family's 20-month-old on standby — then the real problems began Airline apologizes and offers flight compensation and a travel voucher after family's rough ride Before taking his case to small claims court, Hennigar submitted a request for damages to Sunwing. The airline, without discussion, eventually refunded $2,503 to his credit card. In his small claims case, which he filed in September 2024, Hennigar asked the court to order Sunwing to pay him the remaining cost he incurred as a result of the cancellations, which totalled $2,652.76. Sunwing argued that the federal air passenger regulations upon which Henningar's case relied pertained primarily to 'large carriers' and that it was not a large carrier. Hennigar agreed. He turned to another piece of legislation, the 1999 Convention for the Unification of Certain Rules for International Carriage by Air — commonly referred to as the Montreal Convention. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW He successfully argued that the word 'delay' in Article 19 of the Montreal Convention included the cancellation of a flight — that a cancellation by definition amounts to a delay of the intended arrival date and time. Richardson agreed. The Advocate Airline compensation horror stories take flight. Here's why it may get a whole lot worse After sharing a traveller's odyssey for compensation from Turkish Airlines last week, readers He ordered Sunwing to pay Hennigar for the extra cost of the substitute tickets he purchased himself from Air Canada and layover expenses for a total of $2,652.76 plus costs of $200. There are a surprising number of people named Jason Hennigar in Nova Scotia. I left phone and Facebook messages with three of them but never connected with the right one. If you're reading this Jason, I'd still love to talk with you.

Vermilion Energy Inc. Announces Agreement to Sell United States Assets and Provides Updated 2025 Guidance
CALGARY, AB, June 5, 2025 /CNW/ - Vermilion Energy Inc. ("Vermilion" or the "Company") (TSX: VET) (NYSE: VET) is pleased to announce that it has entered into a definitive agreement for the sale of its United States assets (the "Assets") for cash proceeds of $120 million (the "Transaction"). View PDF Net proceeds from the Transaction will be directed towards debt repayment to further accelerate deleveraging efforts and strengthen Vermilion's balance sheet. Based on current strip commodity pricing (1) and operational plans, we would expect to exit 2025 with net debt (2) of $1.3 billion, with a trailing net debt to FFO ratio (3) of 1.3 times. The Assets consist of approximately 5,500 boe/d (81% oil and liquids) of production and approximately 10 mmboe of Proved Developed Producing reserves estimated as evaluated by McDaniel & Associates Consultants Ltd. at December 31, 2024. The Transaction has an effective date of January 1, 2025 and is anticipated to close in Q3 2025, subject to the satisfaction of other customary closing conditions. The Transaction agreement includes $10 million of contingent payments (4) based on WTI prices over the two-year period starting July 1, 2025. This Transaction, combined with the sale of our East Finn assets in 2023, completes our exit from the United States, allowing us to focus on our core gas-weighted assets in Canada and Europe. Vermilion would like to sincerely thank our talented and dedicated field teams in Wyoming for their commitment to safe and efficient operations over the past 11 years as well as the technical teams, which provided support from Denver and Calgary. Vermilion is adjusting its 2025 capital budget to a range of $630 to $660 million, reflecting a reduction of approximately $100 million from the mid-point of our previous capital budget range of $730 to $760 million. This reduction reflects the removal of all remaining E&D capital associated with the Saskatchewan and United States divested assets post-closing. Vermilion expects full year and second half 2025 production to range between 117,000 to 122,000 boe/d, 68% natural gas-weighted in the second half of 2025. On a go-forward basis, it is estimated that over 90% of production will come from our global gas portfolio and over 80% of capital is expected be allocated to these assets. Vermilion will continue to evaluate capital investment levels during this period of increased volatility and will adjust capital if necessary to prioritize free cash flow over production growth during 2025 and 2026. * Original 2025 guidance reflects foreign exchange assumptions of CAD/USD 1.40, CAD/EUR 1.48, and CAD/AUD 0.91. Post-Westbrick 2025 guidance, effective March 5, 2025, incorporates the close of the acquisition of Westbrick Energy Ltd. on February 26, 2025, and reflects foreign exchange assumptions of CAD/USD 1.43, CAD/EUR 1.51, and CAD/AUD 0.90. Current 2025 guidance reflects foreign exchange assumptions of CAD/USD 1.40, CAD/EUR 1.56, and CAD/AUD 0.89. **General and administration expense inclusive of expected cash-settled equity based compensation. Advisors Wells Fargo is acting as exclusive financial advisor and Citi is acting as strategic advisor to Vermilion in connection with the Transaction. Torys LLP is acting as legal advisor on the Transaction with Davis Graham & Stubbs LLP acting as co-advisor. (1) 2025 forward strip pricing as at May 20, 2025: Brent US$67.51/bbl; WTI US$63.69/bbl; LSB = WTI less US$4.85/bbl; TTF $18.01/mmbtu; NBP $17.81/mmbtu; AECO $2.23/mcf; CAD/USD 1.40; CAD/EUR 1.56 and CAD/AUD 0.89. (2) Net debt is a capital management measure most directly comparable to long-term debt and is comprised of long-term debt (excluding unrealized foreign exchange on swapped USD borrowings) plus adjusted working capital (defined as current assets less current liabilities, excluding current derivatives and current lease liabilities). More information and a reconciliation to long-term debt, the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of Vermilion's Management's Discussion and Analysis for the three months ended March 31, 2025. Pro forma net debt reflects reported net debt at March 31, 2025 less cash proceeds from the sale of the Saskatchewan assets. (3) Net debt to four quarter trailing fund flows from operations ("FFO") is a non-GAAP ratio and is not a standardized financial measure under IFRS Accounting Standards and therefore may not be comparable to similar measures disclosed by other issuers. Net debt to four quarter FFO is calculated as net debt divided by FFO from the preceding four quarters. Management uses this measure to assess the Company's ability to repay debt. More information can be found in the "Non-GAAP and Other Specified Financial Measures" section of Vermilion's Management's Discussion and Analysis for the three months ended March 31, 2025. (4) Contingency Payment 1: US$3.5MM if NYMEX WTI averages a minimum of US$67.00/bbl between July 1, 2025 – June 30, 2026, and Contingency Payment 2: US$3.5MM if NYMEX WTI averages a minimum of US$65.00/bbl between July 1, 2026 – June 30, 2027.

Orla Mining Delivers Initial Underground Mineral Resource for Camino Rojo in Mexico, Paving the Way for Future Development Planning
3.95 Moz Measured & Indicated & 0.40 Moz Inferred Gold Mineral Resources VANCOUVER, BC, June 5, 2025 /CNW/ - Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) ("Orla" or the "Company") is pleased to provide the first underground Mineral Resource estimate for the Company's Camino Rojo deposit located in Zacatecas, Mexico, representing a down plunge extension from the oxide open pit. This news release presents the 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 (Figures 1, 2a). Zone 22 represents the vertical and down plunge continuation of the Camino Rojo sulphide mineralization. Summary Highlights: Measured and Indicated Mineral Resource: 50.1 Mt at 2.45 g/t Au, 10.6 g/t Ag, and 0.25% Zn, averaging 2.58 g/t AuEq, totaling 3.95 Moz Au, 17.05 Moz Ag, 278 Mlbs Zn, and 4.16 Moz AuEq. Inferred Mineral Resource: 5.6 Mt at 2.21 g/t Au, 10.9 g/t Ag, and 0.21% Zn, averaging 2.33 g/t AuEq, totaling 0.40 Moz Au, 1.95 Moz Ag, 26 Mlbs Zn, and 0.42 Moz AuEq. 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. This represents only a portion of the defined mineralization in Zone 22, with drilling ongoing. The 2025 drilling results from Zone 22 will be incorporated in future resource updates. Recovery model supported by ongoing metallurgical work: The mineral resource is divided into three spatially distinct zones, each with specific processing options for the Caracol-hosted mineralization: heap leaching (3%); cyanidation (CIL) (25%); and flotation followed by pressure oxidation ("POX") as a pre-treatment prior to cyanidation (CIL with POX) (72%). These zones inform the resource recovery assumptions. Initial metallurgical testing indicates that material from Zone 22 is amenable to both cyanide leaching and flotation. Development strategy to advance the initial underground Mineral Resource towards possible future construction decision. This includes additional exploration, development planning for an exploration drift to allow for tighter spaced underground drilling, flowsheet design, further metallurgical testing, engineering studies, and permitting activities. "This initial underground resource marks an important milestone at Camino Rojo. When we acquired the project, the scale of the mineralized system was clear, but the path forward was uncertain. This resource crystallizes our belief in the potential for a future underground operation. Our team has taken a systematic approach, and we will now look to increase confidence and establish a clear path to construction." – Jason Simpson, President and CEO "Over the past few years, our efforts have focused on drilling the sulphide zone, improving the geological model, and extending mineralization down-plunge in the newly discovered Zone 22. We have now delivered a significant initial underground resource, a key milestone that will inform an upcoming Preliminary Economic Assessment and establish the foundation for potential long-term production at Camino Rojo. The deposit remains open down plunge and at depth, and we remain committed to continued exploration and unlocking the full potential of Camino Rojo." – Sylvain Guerard, Senior Vice President, Exploration Initial Underground Camino Rojo Mineral Resource Estimate: The underground resource, including the Camino Rojo Sulphides and Zone 22, extends from the base of the oxide pit to approximately 1,200 metres below surface (or up to 1,300 metres down plunge from the pit base), covering up to one kilometre along strike and 200 to 400 metres in width (Figures 2a, 2b, 3). The Mineral Resource estimate, prepared by SLR Consulting (Canada) Ltd, includes a resource panel constrained Measured and Indicated Mineral Resource totalling 50.1 Mt at 2.45 g/t Au, 10.6 g/t Ag and 0.25% Zn, equating to 2.58 g/t AuEq. Contained metal amounts to 3.95 Moz gold, 17.05 Moz silver and 278 Mlbs zinc, totalling 4.20 Moz AuEq. The Inferred Mineral Resource totals 5.6 Mt at 2.21 g/t Au, 10.9 g/t Ag and 0.21% Zn, equating to 2.33 g/t AuEq. Contained metal amounts to 0.40 Moz gold, 1.95 Moz silver and 26 Mlbs zinc, resulting in a total of 0.42 Moz AuEq. See Table 1 and Figures 4 to 6 for details. The Mineral Resources reported for Zone 22 are constrained within underground resource panels below the Caracol Formation, which represent the vertical and down plunge continuation of the Camino Rojo sulphide mineralization. Zone 22 has been drilled to nearly one kilometre below the Caracol Formation and remains open at depth and down-plunge. 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, 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. Evolution of Camino Rojo Deposit: Orla's north-to-south drilling programs from Q4-2020 to Q4-2024, together with historical drilling data, have been instrumental in enhancing the geological model. This work has significantly refined the understanding of the distribution and geometry of sulphide-bearing veins hosted within the Caracol Formation, which includes both the oxide and much of the sulphide mineralization (except for Zone 22). Zone 22 had previously been partially intersected by historical drilling but lacked a supporting geological model to define its geometry or potential extension into the deeper carbonate-rich formations below the Caracol Formation. Orla's updated model enabled strategic drilling along a section drilled in 2023, targeting the down-plunge extension of the deposit. This drilling confirmed the model and supported follow-up drilling in 2024 to define and expand Zone 22. Initially, the development path for the sulphide component of the Camino Rojo deposit was conceived as a large open pit operation. However, initial estimates by previous operators, and later by Orla, indicated that such a scenario would require significant waste stripping, extension of the projected open pit onto a third-party property that Orla does not own, and construction of a large processing facility. The underground development scenario offers a more focused, high-value approach. This strategy involves selectively targeting higher-grade and more metallurgically favourable portions of the deposit (those amenable to direct cyanide leaching) as an initial phase of mining. Subsequent phases would address mineralization requiring pre-treatment, such as pressure oxidation, prior to cyanidation. Additionally, the underground development could operate in parallel with the ongoing oxide open pit. The upcoming PEA is expected to evaluate the underground mineral resource as an expansion of the current operation which would allow Orla to retain full project value. Development Pathway / Next Steps: Current and Planned Future Exploration In 2025, Orla is advancing a 15,000-metre drilling program aimed at upgrading and expanding the upper part of the Zone 22 resource, with 11,000 metres drilled to date. Visual drill intercepts continue to support the geological model and continuity of mineralization. This program is expected to be completed in the third quarter and is anticipated to extend and infill the down-plunge extension. The next phase of exploration to support the possible development of the underground deposit (including Zone 22) includes the planning of an underground exploration drift (decline). An exploration drift would provide access for tighter-spaced underground drilling aimed at further resource definition and, in parallel with technical studies, support advancement toward Mineral Reserve estimation. Permitting and early development planning is ongoing, and construction of an exploration drift could commence as early as 2026. In November 2024, Orla submitted permit applications to Mexico's environmental and natural resources agency, SEMARNAT (Mexico's Secretaría del Medio Ambiente y Recursos Naturales). These included amendments to the existing oxide open pit permit. Orla also requested permits for an underground portal and exploration drift to support a potential transition to underground mining at Camino Rojo. The underground portal would be established within the current final open pit. Preliminary Economic Study Engineering and metallurgical studies are currently underway and will intensify and expand, with the objective of delivering a Preliminary Economic Assessment (PEA) in 2026. This PEA is expected to provide a conceptual operational plan and demonstrate the potential value for the development of the underground operations at Camino Rojo. Development Planning While establishing the plan for an exploration decline, Orla will continue metallurgical testing and other technical work with the goal of quickly progressing into feasibility level studies and final permitting for the complete underground operations and the required surface facilities. The aim of the conceptual development plan allows for a seamless transition from open pit mining to underground operations at Camino Rojo. Camino Rojo Deposit: The Camino Rojo deposit comprises three continuous zones with distinct characteristics: The Camino Rojo Oxide Deposit ("Camino Rojo Oxides"), The Camino Rojo Sulphide Deposit ("Camino Rojo Sulphides", or "Sulphides"); and Zone 22 (Figure 2a), an extension of the Sulphides. Longitudinal Sections of the Camino Rojo deposit show the three mineralized zones and new resource block model (Figure 2a), as well as the distribution of gold grades (Figure 2b). The Camino Rojo Oxide zone extends from surface to a vertical depth of approximately 250 metres, covering 900 metres along strike and up to 400 metres in width. The Camino Rojo Sulphide zone lies between 250 and 700 metres below surface (or up to one kilometre down plunge), extending approximately one kilometre along strike and up to 400 metres in width. Zone 22 mineralization has been defined over 500 metres along strike, extending from 700 to 1,300 metres vertical depth below surface (or over 1.2 kilometres down plunge), within a width of 200 to 400 metres, predominantly concentrated along and extending from the dike structure. Figure 3 is a representative cross-section of Zone 22, showing gold mineralization within the different host rock formations. Camino Rojo Oxide and Sulphides Geological Controls The Camino Rojo Oxide and Sulphides zones are predominantly hosted within flat-lying to gently dipping graded sandstone to mudstone beds of the Caracol Formation (Fm), as well as within a steeply northwest-dipping diorite dike. The dioritic dike shows true thicknesses ranging from tens of centimetres to tens of metres, reaching up to 24 metres, with an average of approximately seven metres. Both the Caracol Formation and diorite dike have undergone potassic alteration, predominantly characterized by pervasive adularia alteration. Gold mineralization in the Camino Rojo Sulphides zone is controlled by mutually crosscutting, centimetre-scale Au-Ag-Zn±Pb-bearing veins that dip moderately to steeply northwest and shallowly southwest. These vein sets define gold-bearing mineralized domains that are up to tens of metres thick. In the northeastern portion of the deposit, gold-bearing veins crosscut the dioritic dike. Down plunge, to the southwest and toward the base of the Caracol Formation, these veins continue to crosscut the dike and locally exploit the intrusive contact. Oxidation is pervasive within the upper 150-200 metres of the deposit, transitioning to sulphide mineralization between 200 and 250 metres below surface. However, oxidation extends as deep as 650 metres along structures. Ongoing exploration at Camino Rojo continues to expand the deposit's footprint and refine geological understanding, defining additional mineralization beyond the currently outlined mineral resource. Drilling by Orla, guided by the updated geological model, has confirmed that mineralization extends into lower stratigraphic units, showing styles distinct from those hosted in the overlying Caracol Formation. Zone 22, which represents the vertical and down-plunge continuation of the Camino Rojo Sulphides, has been drilled to nearly one kilometre below the Caracol Formation, extending into the limestone-rich Indidura, Cuesta del Cura, La Peña, and Cupido formations. The zone remains open at depth and down-plunge. To date, mineralization has been identified across all rock formations exposed or drilled at Camino Rojo. The Indidura Formation marks the transition to semi-massive to massive sulphide (Au-Ag-Zn) replacement along bedding (manto) and dioritic dike margins. Individual manto intersections are typically decimetre-scale and are traceable for up to 300 metres along strike and up to 150 metres into the hanging wall and footwall of the dike. Calc-silicate skarn alteration and associated Au-Ag-Cu mineralization are constrained to a halo along the hanging wall and footwall of the dike, extending tens of metres from the dike. Metallurgical Test work and Recovery Model: Metallurgical testing of the Camino Rojo deposit has been conducted through multiple programs by previous operators. Since 2021, Orla has focused on defining optimal recovery processes and maximizing metal recoveries from higher-grade zones suitable for underground mining. This has included bottle roll, flotation, and oxidation test work on both master composite and variability samples from the Camino Rojo Sulphides. All Orla metallurgical studies for the Camino Rojo Sulphides have been completed by Blue Coast Research of Parksville, Canada under the guidance of Andrew Kelly, Based on the metallurgical testing results to date, three conceptual mineral resource process streams have been identified that inform the recovery model assumptions of the Camino Rojo underground mineral resource (Measured, Indicated, Inferred): Heap leach (existing infrastructure), 3% of the tonnage of the underground Mineral Resource, with gold recovery ranging from 40% to 70% Carbon-in-leach (CIL), 27% of the tonnage of the underground Mineral Resource, with a mean gold recovery of 92%, and a mean silver recovery of 36% CIL with Pressure Oxidation (POX): 70% of the tonnage of the underground Mineral Resource, with a mean gold recovery of 85%, and a mean silver recovery of 41%. A separate zinc concentrate can be produced prior to POX with zinc recovery of 80% expected from the highest-grade zones. Figures 4 and 5 illustrates the resource block model based on these three process streams in cross-sectional and longitudinal views, respectively. While some material in the Caracol-hosted mineralization may require POX as a pre-treatment, initial metallurgical results from variability testing in Zone 22 are encouraging, with cyanidation tests returning high gold recoveries, and flotation results demonstrating high zinc recovery at reasonable concentrate grades. Previous news releases outlining Orla's metallurgical test programs and results for Caracol and Zone 22 mineralization are available on the company's website, or under Orla's profile on SEDAR+ at or and on EDGAR at Metallurgical test work is continuing in 2025 to support the planned 2026 PEA, which would include a flow sheet for optimal treatment of the Camino Rojo mineralization. Mineral Resource Details The Camino Rojo underground Mineral Resource was estimated in accordance with the 2014 CIM Definition Standards on Mineral Resources and Reserves, and the 2019 CIM Best Practice Guidelines for the Estimation of Mineral Resources and Mineral Reserves. Geological modeling was completed by Orla in collaboration with SLR Consulting (Canada) Ltd, integrating data from over 400,000 metres of core and 28,000 metres of reverse circulation (RC) drilling. This includes approximately 85,000 metres of drilling performed by Orla between 2020 and 2024. The estimate was generated using inverse distance cubed (ID³) and inverse distance squared (ID 2) interpolation, incorporating capping and outlier restriction of composites to limit the influence of high-grade outliers for gold (Au), silver (Ag), and zinc (Zn). Interpolations were constrained by mineralization domains corresponding to the different styles observed in both the oxide zone (including Kp alteration, high-grade veins, and low-grade shell) and the sulphide zone (including high-grade veins, mantos, skarn, and low-grade shell). Figure 6 presents the Camino Rojo mineral resource block model, classified as Measured, Indicated and Inferred categories. An updated technical report on Camino Rojo (the "Technical Report"), which will contain the Mineral Resource estimate discussed in this release, will be filed within 45 days of the date hereof in accordance with NI 43-101. The Technical Report is intended to be read as a whole, and sections should not be read or relied upon out of context. Data Verification Marie-Christine Gosselin, Senior Resource Geologist at SLR Consulting (Canada) Ltd and the Qualified Person for the Camino Rojo Mineral Resource estimate, visited the site from January 22 to 25, 2024. During the visit, collar locations were verified, along with core storage, security, and sampling procedures. Core from both mineralized and unmineralized zones was examined.

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.
