FINANCIAL AND OPERATIONS UPDATE

CAMINO ROJO OXIDE MINE UPDATE

The Company declared commercial production at Camino Rojo on April 1, 2022. Camino Rojo produced 28,876 ounces of gold in the third quarter, 2022. Year to date gold production totals 77,580 ounces and gold production guidance for the full year 2022 has been increased to a range of 100,000 to 110,000 ounces. Gold sold during the quarter totalled 28,749 ounces while year to date gold sold amounts to 75,064 ounces.

Mining rates have steadily increased, averaging 44,911 tonnes per day in the third quarter. The average grade mined, excluding low grade material that was stockpiled, was 0.77 g/t of gold during the quarter, which is in line with plan.

Camino Rojo achieved record quarterly processing throughput in the third quarter 2022. The average daily stacking rate for the third quarter was 19,200 tonnes per day, which is above the nameplate capacity of 18,000 tonnes per day. Mined ore tonnes are reconciling well to the block model and process recoveries to date are in line with the metallurgical recovery model. Additional ore is being generated from the conversion of previously modelled waste tonnes in the upper benches of the pit.

Third quarter cash costs and AISC totalled $452 and $594 per ounce of gold sold, respectively. The operations have experienced unit price increases across several key reagents and consumables, which have been largely offset by lower than budgeted consumption rates. Capital expenditures totalled $1.8 million in the third quarter which included $0.8 million in sustaining capital. AISC guidance for 2022 (Q2-Q4) remains unchanged at $600 to $700 per ounce of gold sold.

CAMINO ROJO SULPHIDE PROJECT UPDATE

Historical drilling on the Camino Rojo Sulphides, conducted by the previous project owners, indicated the gold grade of the deposit to be widely disseminated and a large, open-pit mining scenario was the favoured development pathway. A lower grade open pit development scenario would necessitate higher capital expenditures for a large processing facility and extensive material handling. To understand if an alternative, more targeted development approach was possible, the presence of higher grades had to be confirmed. It was interpreted that portions of the deposit were comprised of higher grade steeply northwest dipping vein sets. To test for the higher grades and to confirm the geological model, Orla began drilling into the Camino Rojo Sulphides in the opposite (south) orientation of historical drilling. Since the fourth quarter 2020, two phases of drilling have been conducted with the results indicating the presence of continuous, higher-grade gold domains which could be amenable to underground mining, allowing for a smaller processing facility and less material handling. Most recently, the south oriented Phase 2 drill program has returned higher-grade gold intercepts (>2 g/t) over wide widths (>30m). These results are derived from an 8,750-metre drill program being conducted in 2022, to reinforce the geologic model and to continue to confirm the continuity of wide zones of higher-grade gold mineralization. Ten of the 15 diamond drill holes have been completed. Results from the first five drill holes are available on the Company's website and in the news release dated September 12, 2022 (Orla Mining Advances Exploration & Growth Pipeline). Results from the remaining drill holes are expected in early 2023. Selected significant results from the first five holes include:

• Hole CRSX22-05: 1.95 g/t Au over 61.2m, incl. 2.05 g/t Au over 19.5m
• Hole CRSX22-06: 2.56 g/t Au over 41.5m, incl. 4.00 g/t Au over 19.5m
• Hole CRSX22-07A: 3.20 g/t Au over 36.6m
• Hole CRSX22-07B: 2.13 g/t Au over 27.0m, incl. 4.43 g/t Au over 9.5m
• Hole CRSX22-08A: 3.08 g/t Au over 52.5m, incl. 4.37 g/t Au over 28.5m

The first metallurgical results from the Phase 2 drilling confirm the potential for a standalone processing option for the Camino Rojo Sulphides, thereby conserving the potential for the Company to retain 100% ownership in a potential project². Metallurgical testing will continue as each new phase of drill core becomes available.

Most of the gold mineralization at Camino Rojo has been defined in the Caracol Formation where auriferous veins are mostly constrained to a broad envelope of potassic alteration (Kp). Gold mineralization extends deeper into the underlying Indidura and Cuesta del Cura formations (and potentially deeper into other underlying units) along the Dike Zone and Breccia Fault Zone, suggesting these faults may be feeder-like structures for the Camino Rojo deposit.

During the ongoing Orla Phase 2 drill program, selected holes were extended to test the continuity of gold mineralization where the Dike Zone crosscut the Indidura Formation. These drill holes have returned encouraging visual results (assays pending) of the sulphide veins crosscutting bedding and associated calc-silicate alteration within the Indidura Formation. Compilation of historical drill data has confirmed significant gold intercepts over significant widths with a similar style of mineralization elsewhere in the Indidura formation, as well as skarn and calc-silicate alteration associated with manto-type mineralization with semi-massive to massive sulphides replacing bedding in the Cuesta del Cura Formation.

Based on the positive results encountered in the Phase 1 and 2 programs, more closely spaced, south-oriented drilling will be required to fully capture the extent of a potential underground resource. To date, approximately 13,868 metres of directional drilling has been completed which has continued to inform Orla's perspective on the development approach to the deposit. Orla expects to provide details of a Phase 3 south-oriented drill program and metallurgical testwork program in early 2023. This drilling is expected to strengthen the confidence for a Preliminary Economic Assessment ("PEA") that contemplates underground mining. Upon the completion of additional south oriented directional drilling and testwork programs, a PEA is expected to be completed based on the optimal development method for Orla.

Drilling during the planned Phase 3 drill program will focus on infilling the Caracol hosted mineralization (existing resources) and also follow-up on this new and historical drill data, testing the down plunge extension potential of the Camino Rojo Sulphide deposit into the Indidura and Cuesta del Cura formations along the Dike and Breccia zones as well as further Orla's metallurgical planning.

GOLD STANDARD ACQUISITION / SOUTH RAILROAD PROJECT

On August 12, 2022, Orla completed the acquisition of Gold Standard by way of court-approved plan of arrangement (the "Transaction").

Gold Standard's key asset is the 100%-owned South Railroad Project, a feasibility-stage, open pit, heap leach project located on the Carlin trend in Nevada. A Feasibility Study on South Railroad was completed in February 2022 and permitting activities are currently underway. As part of the Transaction, Orla also acquired the Lewis Project ("Lewis"), a large, strategically located, prospective land package on the Battle Mountain trend in Nevada. Orla has begun integrating South Railroad into the Company's growth plans with key priorities for South Railroad to include project permitting, review of project schedule including critical path activities, and assessment of current exploration supporting resource expansion.

Through the remainder of the year, Orla will continue with Gold Standard's 2022 planned program of resource expansion and exploration drilling at key targets on the South Railroad Project. The Company will also commence an additional 5,000 metre RC and core drill program at South Railroad for an additional $1.5 million, bringing the total 2022 planned direct drilling cost spending to $3.0 million across 11,370 metres of drilling. The current and primary objectives are to upgrade and increase oxide resources at the Pinion SB, LT, POD, Sweet Hollow, Jasperoid Wash, and Dixie targets.

EXPLORATION PROGRAM

This year, drilling across the portfolio began in April after preparations and operational ramp-up during the first quarter.

Regional exploration work at Camino Rojo includes reverse circulation drilling ("RC") and continued target definition activities. RC drill testing of near-mine target areas near the Camino Rojo Oxide Mine is underway, with 40% of the program completed at September 30, 2022. The highest priority targets are expected to be drilled along the mine trend in the fourth quarter, 2022, subject to drill permits being issued. Phase 2 of the sulphide drill program is underway, with ten oriented diamond drill holes completed since the program began in April, the details of which are discussed above.

In the second quarter 2022, the planned drill program at Cerro Quema commenced with two diamond drill holes completed in La Pelona target and three holes in La Prieta targets. Drilling in both target areas has returned encouraging results and additional drilling will be planned for 2023. Assay results are available in Orla's news release dated September 12, 2022 (Orla Mining Advances Exploration & Growth Pipeline).

In the third quarter 2022, infill and expansion drilling at Caballito focused on converting resources from the inferred resource to the indicated resource category, providing material for metallurgical testing, and testing the continuity of mineralization and potential extensions of this deposit. This drilling, along with more limited drilling planned at La Pava and Quemita sulphide deposits, will continue through the fourth quarter 2022.

The initial 2022 exploration budget totalled $15 million, with $10 million allocated to Mexico and $5 million allocated to Panama. Supported by the recent exploration success and following the completion of the acquisition of Gold Standard, Orla increased the 2022 spending to $18.0 million.

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.

ADJUSTED EARNINGS (LOSS)

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. We believe these measures are useful to investors because they are important indicators of the strength of our operations and the performance of our core business.

FREE CASH FLOW

The Company believes certain investors and analysts use Free Cash Flow to evaluate the Company's operating cash flow capacity to meet non-discretionary outflows of cash. Net 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 COST

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 external users in assessing operating performance. Figures are presented only from April 1, 2022, as the Camino Rojo Oxide Gold Mine commenced commercial production on that date.

ALL-IN SUSTAINING COST

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 external users 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 herein and the documents incorporated by reference herein, as applicable, 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 (the "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 Exchange Act, which became effective February 25, 2019. 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 SEC Industry Guide 7. Issuers were required to comply with the SEC Modernization Rules in their first fiscal year beginning on or after January 1, 2021. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards. Accordingly, mineral reserve and mineral resource information contained or incorporated by reference herein may not be comparable to similar information disclosed by United States companies subject to the United States federal securities laws and the rules and regulations thereunder.

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 SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", U.S. investors should not assume that all or any part of the mineralization in these categories will be converted into a higher category of mineral resources or into mineral reserves without further work and analysis. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that all or any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable without further work and analysis. Further, "inferred mineral resources" have a greater amount of uncertainty and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred mineral resources will be upgraded to a higher category without further work and analysis. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms are "substantially similar" to CIM Definitions, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, 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 SEC Industry Guide 7.
