Commissioning activities at the Camino Rojo Oxide Mine are substantially complete, and mining and processing throughput rates and availabilities are in line with the ramp-up plan. Capital expenditures for the Camino Rojo Oxide Mine were $120.5 million at February 28, 2022, against the current project estimate at completion of $134.1 million, which is consistent with the total project capital expenditure estimate. The remaining project spend is expected to occur in the first half of the year. The project estimate at completion includes $3.5 million in unallocated contingency that is not forecasted to be spent. Management therefore anticipates the Camino Rojo Oxide Mine to be completed within the total project capital estimate.

The main construction activities completed during the fourth quarter of 2021 included ramp up of mining activities, mechanical completion of the crushing system, conveying/stacking systems and Merrill-Crowe plant. During the quarter, wet commissioning of all the process areas was completed as well camp facilities. Placement of overliner ore material on the heap leach pad and ore stacking began in early October in preparation for cyanide leaching which commenced in mid-November leading to first gold pour on December 13, 2021.

Site activities that advanced early in the first quarter of 2022 included ramping up mining, crushing and stacking rates as well as increasing capacity through the Merrill-Crowe plant. Construction activities included installation of heap leach liner in cell two and event pond, placement of overliner material on cell two of the heap leach, commissioning of the third and final overland conveyor, and construction of the airstrip.

CAMINO ROJO SULPHIDE PROJECT UPDATE

Orla continues to evaluate multiple development scenarios on the Camino Rojo Sulphide Project. The development scenarios being considered to potentially form the basis of a Preliminary Economic Assessment ("PEA") currently include: (1) an underground mining option, (2) an open pit mining option with processing at a to-be-constructed sulphide facility at Camino Rojo, and (3) an open pit mining option with processing at Newmont's Peñasquito plant. Based on the additional drilling and testwork to date, all development options remain possible.

Following a successful core drill program in 2021, an 8,250m follow-up drilling phase is planned in 2022. The 2021 program confirmed wide zones of higher-grade gold mineralization within the sulphide deposit while also providing material for new metallurgical study, which remains in progress. The 2021 drill program drilled a 6,079m, 14-hole program of south-oriented holes on a 100-250m drill spacing and the 2022 program will infill drill and reducing the spacing to 50-125m. This tighter drill spacing on the more optimal south orientation, combined with the extensive south to north historical drilling, will seek to reinforce the geological model and confirm continuity of wide zones of higher-grade gold mineralization, supporting the advancement of development planning and PEA targeted for year end 2022.

CERRO QUEMA OXIDE PROJECT UPDATE

In July 2021, Orla issued the results of a PFS and mineral resource and mineral reserve estimates for Cerro Quema. The PFS demonstrates the possibility of a low cost, high return heap leach project. The estimated after-tax net present value ("NPV") (5% discount rate) for Cerro Quema is $176 million, with an after-tax internal rate of return ("IRR") of 38% at a gold price of $1,600 per ounce. The Company will continue to advance the Cerro Quema engineering once the environmental permit and concession renewals are received which would provide the basis for a construction decision.

In February 2021, the Ministry of Environment conducted its final site inspection of the project. As a result of the positive site inspection review, the Category 3 Environmental and Social Impact Assessment is in the final stage of approval. The final process will now require the signing and publication of the resolution in the official government register (the "Gazette") — this process is pending.

In May 2021, the extension of the exploitation contracts Cerro Quema were signed by both the Ministry of Commerce and Industry and by Orla. The documents are currently with the Comptroller General for final review and approval. The final process will now require the signing and publication of the resolution in the official government register (the "Gazette") — this process is pending.

CABALLITO COPPER-GOLD PROJECT UPDATE

During the quarter, the Company announced the mineral resource estimate for the Caballito copper-gold deposit at the Company's Cerro Quema project ("Cerro Quema") located in the Azuero Peninsula, Los Santos Province, Panama. Caballito is a large, copper-gold deposit that represents an opportunity for the Company to potentially transform the scale and scope of Cerro Quema beyond the separate oxide project outlined in the July 2021 Pre-Feasibility Study ("PFS").

The mineral resource estimate for the Caballito copper-gold deposit consists of the following:

Table 3a: Caballito Sulphides

Non-GAAP Measures

The Company has included certain performance measures in this press 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.

ALL-IN SUSTAINING COSTS ("AISC") —

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. Upon commencing commercial production and reporting actual AISC, we will provide a reconciliation to IFRS figures then presented.

Cautionary Note to U.S. Readers

The disclosure contained or referenced herein uses mineral reserve and mineral resource classification terms that comply with reporting standards in Canada, and mineral reserve and mineral resource estimates are made in accordance with Canadian NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Definition Standards"). Canadian NI 43-101 establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the mineral reserve disclosure requirements of the United States Securities Exchange Commission (the "SEC") set forth in Industry Guide 7. Consequently, information regarding mineralization contained or referenced herein is not comparable to similar information that would generally be disclosed by U.S. companies under Industry Guide 7 in accordance with the rules of the SEC which applied to U.S. filings prior to the current SEC Modernization Rules (as defined herein). Further, the SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Securities Exchange Act of 1934 ("Exchange Act"). These amendments became effective February 25, 2019 (the "SEC Modernization Rules") and, commencing for registrants with their first fiscal year beginning on or after January 1, 2021, the SEC Modernization Rules replace the historical property disclosure requirements included in SEC Industry Guide 7. As a foreign private issuer that files its annual report on Form 40-F 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. The SEC Modernization Rules include the adoption of terms describing mineral reserves and mineral resources that are "substantially similar" to the corresponding terms under the CIM Definition, but 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 mineral reserve or mineral resource estimates under the standards adopted under the SEC Modernization Rules. U.S. investors are also cautioned that while the SEC recognizes "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under the Modernization Rules, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. 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, investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence 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 the "inferred mineral resources" exist. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. For the above reasons, information contained or referenced herein regarding descriptions of our mineral reserve and mineral resource estimates is not comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements of the SEC under either Industry Guide 7 or SEC Modernization Rules.

¹ AISC is a non-GAAP measure. See the "Non-GAAP Measures" section of this news release for additional information.
