2022 Exploration: Cerro Quema (Panama)

Cerro Quema consists of a pre-feasibility stage heap leach gold project, a copper-gold sulphide resource, and a suite of exploration targets on a prospective land package. The project is located on a 15,000-hectare concession on the Azuero Peninsula in the Los Santos Province of Southwestern Panama. In 2022, exploration drilling at Cerro Quema began with regional exploration at the La Prieta and La Pelona targets before moving to metallurgical, infill, and expansion drilling at Caballito and La Pava mineralized zones and early-stage follow-up drilling at Quemita Norte target. In total, 9,044 metres were drilled in Panama during the year.

Exploration at the Caballito and La Pava deposits and the Quemita Norte target in the second half of 2022 continued to generate significant drill intersections. These new drill results build on the previously reported 2022 positive drill results generated at the early stage La Pelona and La Prieta regional targets, (see news release dated September 12, 2022 - Orla Mining Advances Exploration & Growth Pipeline), and further highlight the presence of significant copper and gold mineralization at the Cerro Quema project.

La Prieta and La Pelona:

The 2022 exploration program began by drill testing two regional targets: La Pelona and La Prieta. As previously reported, both regional targets returned positive drill results, including new shallow oxide-hosted gold mineralization at La Pelona (0.46 g/t gold over 104.8m, and 0.27 g/t gold over 113.7m) and sulphide-hosted gold-copper mineralization at La Prieta (27.3 g/t gold and 0.91% Cu over 0.75m and 1.01 g/t gold over 13.5m) (see news release dated September 12, 2022 - Orla Mining Advances Exploration & Growth Pipeline). Follow-up drilling on these encouraging results from these regional exploration targets is planned for early 2023.

Caballito:

Orla completed 20 core drill holes (4,339 metres) including three drill holes (599 metres) for metallurgical study at the Caballito deposit in the second half of 2022. Infill drilling was undertaken to increase drilling density and to better define the geometry and extent of mineralization. These recent drill holes have helped to 1) improve the understanding within the core area of the deposit, the geological controls, continuity, and geometry of mineralization, and to 2) better define and constrain the extent of the boundaries of mineralization.

Notable results from 2022 drilling:

• CQDH-22-199: 0.58% Cu, 0.52 g/t Au over 31.4 m (Oxide) from 33.7 m
• CQDH-22-192: 0.04% Cu, 0.69 g/t Au over 34.2 m (Oxide) from 14.2 m and
  1.54% Cu, 0.52 g/t Au over 47.8 m (Sulphide) from 100.5 m
• CQDH-22-195: 0.03% Cu, 0.61 g/t Au over 85.7 m (Oxide) from 9.0 m and
  1.91% Cu, 0.13 g/t Au over 21.2 m (Sulphide) from 94.7 m
• CQDH-22-199: 0.58% Cu, 0.52 g/t Au over 31.4 m (Oxide) from 33.7 m
• CQDH-22-197: 2.62% Cu, 0.39 g/t Au over 19.5 m (Sulphide) from 187.7 m
• CQDH-22-200: 1.72% Cu, 0.10 g/t Au over 18.0 m (Sulphide) from 233.3 m and
  0.89% Cu, 0.07 g/t Au over 90.3 m (Sulphide) from 282.8 m
• CQDH-22-206: 0.84% Cu, 0.34 g/t Au over 65.2 m (Sulphide) from 44.6 m
• CQDH-22-223: 0.17% Cu, 0.33 g/t Au over 24.7 m (Oxide) from 14.2 m and
  0.98% Cu, 0.20 g/t Au over 105.2 m (Sulphide) from 90.4 m

La Pava:

Orla completed eight core holes (1,343 metres) at La Pava in 2022, targeting potential extensions of sulphide mineralization defined by historical drilling beneath the oxide mineralization. The new drill results together with extensive historical drilling indicate the presence of significant copper-gold sulphide mineralization. The sulphide Cu-Au mineralization at La Pava is now defined over a strike length of approximately 800 metres, over a width of 280 metres, consisting of stacked sub horizontal lenticular shapes with thicknesses up to 35 metres, beneath the oxide gold mineralization. In addition, some of the 2022 drill holes cut oxide material while targeting the sulphide mineralization, confirming the upper oxide mineralization zone.

Notable 2022 drill results:

• CQDH-22-204: 0.06% Cu, 1.04 g/t Au over 69.0 m (Oxide) from 0.0 m and
  0.69% Cu, 0.32 g/t Au over 15.0 m (Sulphide) from 69.0 m and
  0.50% Cu, 0.29 g/t Au over 24.0 m (Sulphide) from 110.6 m
• CQDH-22-209: 0.45% Cu, 0.16 g/t Au over 39.6 m (Sulphide) from 117.2 m and
  0.78% Cu, 0.17 g/t Au over 6.8 m (Sulphide) from 167.7 m

Selected historical drill results in sulphide below the La Pava oxide mineralization:

Quemita Norte:

The Quemita Norte target is located 200 metres northwest of the Quemita Oxide gold deposit. Five core holes (1,328 metres) were completed, following-up on a historical and previously reported intersection obtained in hole CQDH-17-112 (1.36% Cu & 0.15 g/t Au over 26.5 metres and 0.60% Cu & 0.12 g/t Au over 124.4 metres (see the Company’s August 24, 2017 news release – Orla Provides Update on its Projects). The 2022 drill program extended copper mineralization over approximately 180 metres on a northwest-southeast drill section and 210 metres along strike. The mineralization remains open along strike and additional drilling is required to further define the extent of mineralization.

Notable sulphide results:

• CQDH-22-208: 0.54% Cu, 0.14 g/t Au over 58.1 m, from 30.0 m
• CQDH-22-212: 1.35% Cu, 0.24 g/t Au over 19.9 m from 162.2 m
• CQDH-22-203: 0.38% Cu, 0.18 g/t Au over 28.8 m from 137.2 m and
  1.09% Cu, 0.10 g/t Au over 9.5 m from 59.7 m

2023 Exploration Plans & Strategy: Cerro Quema (Panama)

A $5 million exploration budget is planned in Panama in 2023 which would include approximately 5,500 metres of core drilling.

Targeting Discoveries:

The 2023 exploration program will follow-up on the encouraging results generated at La Pelona and La Prieta regional targets in 2022 (see news release dated September 12, 2022 - Orla Mining Advances Exploration & Growth Pipeline). Upon completion of the exploration and drilling campaign during the dry season of the first half of 2023, exploration and operational activities will be reduced in Panama. Data interpretation of the results will take place primarily in the second half of 2023 while on-the-ground activities will be minimal.

Drilling at La Pelona in 2022 confirmed high sulphidation type gold mineralization associated with argillic alteration, vuggy silica, overlying an Induced Polarization (IP) chargeability anomaly. Oxide gold mineralization has been intersected in drilling over a strike length of 300 metres and from surface to 150 metres vertically and remains open along strike and at depth within sulphide mineralization. In 2023, the drill program will consist of approximately 3,000 metres of core drilling to test the broader alteration, gold-in-rock, and IP chargeability anomalies over a strike length of approximately two kilometres.

Drilling at La Prieta in 2022 intercepted copper-gold mineralization associated with pyrite, chalcopyrite, and bornite in quartz stockworks, quartz veins and hydrothermal magnetite-pyrite matrix breccias hosted in a multi-phase dioritic intrusion. Multiple intercepts, ranging from surface to 490 metres down-hole, of anomalous gold (>100 ppb Au) and copper (>0.1% Cu) and significant mineralization (>0.5 g/t Au and/or >0.3% Cu) were intersected in 2022. In 2023, the drill program will consist of approximate 2,500 metres of core drilling to follow-up on encouraging 2022 results.

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 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.
