Financial and Operations Update

Financial and Operations Summary

The Camino Rojo Oxide Gold Mine achieved quarterly gold production of 32,425 ounces of gold in the third quarter of 2023 at an average ore stacking rate of 19,205 tonnes per day. The average mining rate during the third quarter was 31,820 tonnes per day with a strip ratio of 0.59. The average grade of ore processed during the third quarter was 0.85 g/t gold, in line with our plan. Gold sold during the third quarter 2023 totaled 31,061 ounces. Subsequent to quarter end, October 2023 gold production totalled 11,759 ounces, a monthly record for the Company.

Tonnes of waste mined remained lower than planned during the quarter as the Company await receipt of permits from the Secretariat of Environment and Natural Resources (known as "SEMARNAT") for access to certain areas of the pit. The Company does not expect the delay in obtaining the permits to have any impact on our 2023 production guidance. However, Orla expects waste tonnes to remain below average for the remainder of 2023, resulting in lower mining costs for the year.

Third quarter cash costs and AISC totaled $527 and $743 per ounce of gold sold, respectively. The key contributors to the lower AISC are: (i) lower waste tonnes mined, (ii) lower blasting costs, and (iii) lower maintenance costs.

At Camino Rojo, metallurgical laboratory column tests have indicated that reducing the size of the crushed ore from 28 mm to 23 mm increased the overall recovery of gold and silver. Changes to the crushing circuit were implemented in early August and the initial indication are that gold and silver recoveries are increasing above plan. The Company will continue to monitor the results of the continued optimization on the heap leach performance which has a 90 day leach cycle.

The Company revised its full year AISC guidance in August 2023, reducing the range to $700 to $800 per ounce of gold sold from its original guidance of $750 to $850 per ounce. The reduced cost guidance was mainly driven by lower waste tonnes mined during the first half of 2023 which is expected to continue for the remainder of the year due to limited access to certain areas of the pit as the Company await permits from the SEMARNAT, as noted above. The Company maintains the AISC guidance of $700 to $800 per ounce of gold sold.

On October 16, 2023, the Company increased its full year gold production guidance range to 110,000 to 120,000 ounces from its initial guidance of 100,000 to 110,000 ounces. Sustaining capital during the third quarter of 2023 totaled $2.5 million. This covered items such as the construction of a dome over the ore stockpile for dust control, the construction of water wells and IT network infrastructure, as well as drilling and evaluation work at the Layback Area.

Exploration and Projects Update

In the third quarter, exploration was focused on drilling at Camino Rojo in Mexico and South Railroad in Nevada, US.

Camino Rojo Exploration Update (Mexico)

Orla's 2023 Camino Rojo exploration budget is $22 million. Approximately 80% of the planned 34,000 metres of infill drilling on the Sulphides has been completed and is intended to advance the understanding of the deposit. The regional exploration drill program is testing priority regional targets in an effort to make new satellite discoveries. Approximately 85% of the planned 15,000 metre regional drilling program has been completed to date.

High grade gold and zinc intersections continue to support potential for Camino Rojo Sulphides Extensions

Additional drilling targeting polymetallic (Au-Ag-Zn) semi-massive to massive sulphide mineralization below the Caracol Formation hosted Sulphides was completed in the third quarter of 2023. These intercepts indicate mineralization remains open at depth along and adjacent to interpreted feeder-like structures for the currently defined Camino Rojo deposit. Approximately 20% of the 2023 Sulphides drill holes were extended, beyond the boundaries of the current open pit resource estimate, to test the down plunge continuity of gold mineralization along the steep northwest dipping Dike Structural Zone.

As reported in Q2 2023 (Orla Mining Reports Second Quarter 2023 Results), drill hole CRSX23-15C intersected significant polymetallic sulphide replacement mineralization beneath the Caracol Formation hosted Sulphides along and adjacent to the Dike Structural Zone. This intersection, supported by a new geological model, suggests the extension of the currently defined sulphide mineralization. Based on this model, and success of hole 15C, a drill section was designed to follow-up on historical drill results 250m down plunge of hole 15C, 450m from the limit of the current resources. Visual results from the step-out drill section indicate a similar style of semi-massive to massive sulphide mineralization as was intercepted in hole 15C. Based on visual results, sulphide mineralization remains open at depth. Assay results are pending.

Following positive results from the 2023 Sulphides Extension drill program, near mine exploration efforts in 2024 are anticipated to shift from infill drilling of the Caracol-hosted Sulphides to focus on assessing the down dip and down plunge extension of the CR deposit while continuing to advance economic evaluation of the Caracol-hosted mineralization.

Drill results at Camino Rojo Sulphides continue to support potential for underground development

Drilling into the Camino Rojo Sulphides continues to intercept wide zones (>15m down-hole drill intersections) of higher-grade gold mineralization (>2g/t Au), and in conjunction with metallurgical results from the 2021 drilling (see news release dated May 9, 2022), supports the potential for underground development and a standalone processing option for the Camino Rojo Sulphides.

The 2023 infill drilling is expected to be completed in the fourth quarter 2023. Drill results from the 2023 drill program will inform a future update to a potential underground resource estimate, mining methods, and production decisions.

See the Company's news release dated June 22, 2023, and full drill results are available at www.orlamining.com.

Near mine layback drilling seeking to confirm mineralization with targeted mineral resource addition

The Company completed drilling in the oxide pit layback to confirm and delineate mineralization on the Fresnillo plc ("Fresnillo") property, located immediately north of and adjacent to the Camino Rojo Oxide Mine open pit. Results from the Layback Program were as expected and will be included in the 2023 year-end Mineral Resource and Mineral Reserve estimate update expected to be published in the first quarter of 2024.

South Railroad Exploration Update (Nevada, US)

The first full year of exploration at South Railroad, following Orla's acquisition of the project in August 2022, is progressing with drilling continuing through the third quarter. The exploration objectives at South Railroad are to upgrade and grow resources at satellite deposits and drill test multiple targets for new discovery. Drilling in the third quarter focused on infill drilling to support upgrading resources at the North Bullion deposit as well as testing the pit extension potential of the Dark Star and Pinion deposits. Infill and extension drilling is expected to be completed in the fourth quarter of 2023. Multiple exploration targets will also be drill tested across the South Railroad project during the fourth quarter.

Panama Update

In November 2023, the National Assembly of Panama passed Bill 1110 that included a moratorium on granting, renewing, or extending concessions for the exploration, extraction, or exploitation of metal mining in Panama. The legislation was passed in response to public opposition to certain mining activities in the country. The impact of these developments on the Company's Cerro Quema Project remains uncertain and rapidly changing. The Company expects that various factors, including potential court challenges and the May 2024 Panamanian general election, may impact its strategy in Panama. The Company will continue to monitor these developments and make an informed assessment of its strategy once additional information is available.

Orla believes that the Cerro Quema Project could be an important social and economic contributor to the host community of Panama. The Company is committed to sustainable mining which includes sharing the benefits created by the mining operations and being responsible environmental stewards of the local environments where it operates.

2023 Guidance Update

The Company is advancing the construction of the third phase of the heap leach pad at Camino Rojo in the fourth quarter. This construction is ahead of schedule and is expected to increase sustaining capital in 2023 by $4 million. The Company maintains its 2023 full year AISC guidance of $700 to 800 per ounce gold sold.

Third Quarter 2023 Conference Call

Orla will host a conference call on Tuesday, November 14, 2023, at 10:00 AM, Eastern Time, to provide a corporate update following the release of its financial and operating results for the third quarter 2023:

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 gold projects: (1) Camino Rojo, located in Zacatecas State, Mexico, (2) South Railroad, located in Nevada, United States, and (3) Cerro Quema, located in Los Santos Province, Panama. Orla is operating the Camino Rojo Oxide Gold Mine, a gold and silver open-pit and heap leach mine. The property is 100% owned by Orla and covers over 160,000 hectares which contains a large oxide and sulphide mineral resource. Orla also owns 100% of the South Railroad Project, a feasibility-stage, open pit, heap leach gold project located on the Carlin trend in Nevada. Orla also owns 100% of Cerro Quema located in Panama which includes a pre-feasibility-stage, open-pit, heap leach gold project, a copper-gold sulphide resource, and various exploration targets. 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.

Non-GAAP Measures

The Company has included certain performance measures in this news release which are not specified, defined, or determined under generally accepted accounting principles (in the Company's case, International Financial Reporting Standards ("IFRS"")). These 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, the Company uses 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 generally accepted accounting principles ("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. The Company believes the measure is useful in understanding the gold price realized by the Company throughout the period.

Net Debt

Net debt is calculated as total debt adjusted for unamortized deferred financing charges less cash and cash equivalents and short-term investments at the end of the reporting period. This measure is used by management to measure the Company's debt leverage. The Company believes that in addition to conventional measures prepared in accordance with IFRS, net debt is useful to evaluate the Company's leverage and is also a key metric in determining the cost of debt.

Adjusted Earnings (Loss) and Adjusted Earnings (Loss) per share

Adjusted earnings (loss) excludes deferred taxes, 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. The Company believes these measures are useful to market participants because they are important indicators of the strength of operations and the performance of the core business. With the addition of PSUs at the end of Q1 2023, the Company expects greater volatility in share-based payments expense going forward. Accordingly, the effect of these PSU's in the calculation of adjusted earnings was excluded.

Companies may choose to expense or capitalize their exploration expenditures. The Company expenses exploration costs based on its accounting policy. To assist the reader in comparing against those companies which capitalize their exploration costs, please note that included within Orla's net income (loss) for each period are exploration costs which were expensed, as follows:

Free Cash Flow

The Company believes market participants use Free Cash Flow to evaluate the Company's operating cash flow capacity to meet non-discretionary outflows of cash. Free Cash Flow is not meant to be a substitute for the cash flow information presented in accordance with IFRS. Free Cash Flow is calculated as the sum of cash flow from operating activities and cash flow from investing activities, excluding certain unusual transactions.

Cash Costs and All-In Sustaining Costs

The Company calculates cash cost per ounce by dividing the sum of operating costs and royalty costs, net of by-product silver credits, by ounces of gold sold. Management believes that this measure is useful to market participants in assessing operating performance.

The Company has provided an AISC performance measure that reflects 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 dated November 14, 2018. Orla believes that this measure is useful to market participants in assessing operating performance and the Company's ability to generate free cash flow from current operations.

Figures are presented only from April 1, 2022, as the Camino Rojo Oxide Gold Mine commenced commercial production on that date.

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 Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("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, 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 or under the prior standards of Industry Guide 7. 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.
