Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) is pleased to provide an update on exploration at the Camino Rojo Extension, now referred to as “Zone 22”.

Summary Details:

• Expanded Resource Potential: Drilling has extended mineralization 800 metres beyond the current open-pit resource, with Zone 22 remaining open at depth and along strike.
• Drilling Progress: Over 32,000 metres drilled in 2024, with an additional 3,000 metres planned by year-end.
• High-Grade Intersections: Notable results include 31.5 g/t AuEq over 2.7m and 11.2 g/t AuEq over 4.5m, among others.
• Copper-Gold Discovery: A distinct Cu-Au-Ag mineralization event was identified, with copper grades up to 4.95%.
• Upcoming Resource Estimate: An initial underground resource estimate for the Camino Rojo Sulphides, incorporating historical and 2024 Caracol-hosted intersections as well as a portion of the newly defined Zone 22 mineralization, is expected in early 2025, supporting a Preliminary Economic Assessment.

Drill Highlights:

• 31.5 g/t AuEq over 2.7m, incl. 143.4 g/t AuEq over 0.6m (Hole CRSX24-36C)
• 11.2 g/t AuEq over 4.5m, incl. 22.4 g/t AuEq over 1.3m (Hole CRSX24-40A)
• 11.1 g/t AuEq over 2.8m, incl. 16.9 g/t AuEq over 1.5m (Hole CRSX24-40A)
• 5.68 g/t AuEq over 4.9m, incl. 27.8 g/t AuEq over 0.5m (Hole CRSX24-31)

“The existing mineralization in the upper Caracol-host already set a strong foundation for the initial underground sulphide resource. It is now becoming clear that the future project will be enhanced by the Zone 22 Extension, and we continue to be impressed with the drill results: high-grade, polymetallic, and favourable metallurgy. Zone 22 remains wide-spaced drilled and open down-plunge, offering significant potential for further infill and step-out drilling to contribute to both resource growth and upgrades.”

 – Sylvain Guerard, Orla’s Senior Vice President, Exploration

Mineralization 800 metres Beyond Current Defined Resource

Recent drilling confirms both steep (dike-parallel) and flat (manto-type) high-grade polymetallic Au-Ag-Zn-(±Pb) mineralization, extending 600 metres down-plunge and 500 metres along strike, parallel to the dike structure. The deepest down-plunge holes, with the program ongoing, have intersected mineralization up to 800 metres down-plunge from the resource limit. This news release presents results from 13 drill holes (11,318 metres) completed since the June 26, 2024, release (see Figures 1 and 2).

High Grade, Polymetallic

Zone 22 shows narrow, high-grade intervals with individual grades up to 140.5 g/t Au over 0.6 m (CRSX24-36C), 393.4 g/t Ag over 1.1 m (CRSX24-39), 4.95% Cu over 1.2 m (CRSX24-36A), 13.95% Zn over 0.7 m (CRSX24-25H), and 7.23% Pb over 1.5 m (CRSX24-40A).

Twenty new significant intersections, including four with a grade-by-thickness factor exceeding 30 g/t AuEq * m (see Figure 3), were found outside the current resource. Intersections range from 0.5 to 6.8 metres, with true widths from 0.4 to 4.9 metres. One of the deepest high-grade intersections was at approximately 1,300 metres vertical depth, returning 31.5 g/t AuEq over 2.7 m, including 143.4 g/t AuEq over 0.6 m (Hole CRSX24-36C).

Copper – Gold Mineralization Event

In addition to polymetallic (Au-Ag-Zn) sulphide replacement and skarn-style mineralization characteristic of Zone 22, 2024 drilling at Camino Rojo identified a distinct Cu-Au-Ag mineralization event. This mineralization is associated with a newly identified felsic dike and was primarily intersected in the deepest down-plunge extension area by holes CRSX24-36A and CRSX24-40. Significant Cu-Au-Ag intervals with narrow high-grade copper intersections were drilled in this area, which remain open at depth and along strike, including:

• CRSX24-36A: 1.59% Cu, 1.01 g/t Au, and 63.5 g/t Ag (3.90 g/t AuEq) over 6.6m, including 4.95% Cu, 3.08 g/t Au, and 63.5 g/t Ag (12.1 g/t AuEq) over 1.2m.
• CRSX24-40: 0.91% Cu, 0.93 g/t Au, and 24.7 g/t Ag (2.45 g/t AuEq) over 15m, including 4.67% Cu, 2.69 g/t Au, and 105 g/t Ag (10.2 g/t AuEq) over 0.5m.

Drill Hole Detailed Highlights

Significance of Results

The latest 2024 drill results confirm that the Camino Rojo mineralized system remains open at depth, along the dike structure, and beyond the current resource limits. Recent drilling has intercepted high-grade Au-Ag-Zn massive sulphide mineralization which is narrower and higher grade than typical Caracol-hosted mineralization (see Figure 4). Additionally, new Cu-Au-Ag skarn-related mineralization has been discovered, suggesting potential overprinting of Au-Ag-Zn zones, which may lead to areas of enriched polymetallic mineralization.

The Au-Ag-Zn mineralization primarily follows the main dike structure and secondary parallel structures with steep geometry and sub-horizontal components extending 100-150 metres on either side of the dike and approximately 500 metres along strike (see Figure 5). Initial metallurgy results suggest compatibility with cyanide processing and flotation methods (see June 26, 2024 news release). Further metallurgical test work on both mineralization styles is planned for 2025.

In the CRSX24-40 series drillholes, approximately 900 metres down-plunge, a quartz-feldspar porphyry dike hosting chalcopyrite veins was identified. Associated higher-grade copper mineralization in this area reaches up to 4.95% Cu, along with Au-Ag, suggesting that drilling is approaching a higher-temperature zone with the potential to vector into a stronger, more mineralized part of the system, with this Cu-Au-Ag mineralization remaining open at depth and along strike.

Exploration Planning

Four rigs are operating through the end of the year to target the down-plunge extension 0.5 to 1 kilometre beyond current resources. In the first half of 2025, Orla plans to release an initial underground resource estimate for the Sulphides Project, incorporating historical and 2024 Caracol-hosted intersections as well as a portion of the newly defined Zone 22 mineralization. Additional 2025 drilling is planned to further delineate, expand, and upgrade Zone 22 resources.

This release presents drilling since the June 26, 2024 update (Orla Mining Reports Positive Drilling Intersections and Metallurgical Results at Camino Rojo Sulphide Extension).

Additional Technical Information

All mineralized interval lengths reported are down-hole intervals, with true width estimates ranging from 60-91% for the reported interval for all composites >5 grade-by-thickness factor (Au g/t*m). See Table 1 in the Appendix of this news release for estimated true widths of individual composites. A standard sampling length of 1.5 metre is used with a minimum of 0.5 metres when required based on geological contacts. Drill core is mainly HQ diameter, with reduction to NQ where necessary due to drilling depth. The reported composites were not subject to “capping” of high grades. Orla believes that applying a top cut would have a negligible effect on overall grades. Composites for the sulphide drilling were calculated using 2.0 g/t AuEq cut-off grade and maximum 3 metres consecutive waste

Quality Assurance / Quality Control –2024 Drill Program

All gold results at Camino Rojo were obtained by ALS Minerals (Au-AA23) using fire assay fusion and an atomic absorption spectroscopy finish. All samples are also analyzed for multi-elements, including silver, copper, lead and zinc using a four-acid digestion with ICP-AES finish (ME-ICP61) method at ALS Laboratories in Canada. If samples were returned with gold values in excess of 10 ppm or base metal values in excess of 1% by ICP analysis, samples are re-run with gold (Au-GRA21) by fire assay and gravimetric finish or base metal by (OG62) four acid overlimit methods. Drill program design, Quality Assurance/Quality Control and interpretation of results were performed by qualified persons employing a Quality Assurance/Quality Control program consistent with NI 43-101 and industry best practices. Standards were inserted at a frequency of one in every 50 samples, and blanks were inserted at a frequency of one in every 50 samples for Quality Assurance/Quality Control purposes by the Company as well as the lab. ALS Minerals and ALS Laboratories are independent of Orla. There are no known drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the drilling data at Camino Rojo.

Historical drill results at Camino Rojo were completed by Goldcorp. Inc. (“Goldcorp”), a prior owner of the project. The Company’s independent qualified person, Independent Mining Consultants, Inc. was of the opinion that the drilling and sampling procedures for Camino Rojo drill samples by Goldcorp (and prior to its acquisition by Goldcorp, Canplats Resources Corporation) were reasonable and adequate for the purposes of the Camino Rojo Report (as defined below), and that the Goldcorp QA/QC program met or exceeded industry standards. For additional information, see the Company’s technical report entitled “Unconstrained Feasibility Study NI 43-101 Technical Report on the Camino Rojo Gold Project – Municipality of Mazapil, Zacatecas, Mexico” dated January 11, 2021 (the “Camino Rojo Report”), which is available on SEDAR+ and EDGAR under the Company’s profile at www.sedarplus.ca and www.sec.gov, respectively.

Gold Equivalent Calculations

The following metal prices in USD were used for the gold metal equivalent calculations: $1,750/oz gold, $21/oz silver, $0.90/lb lead, $1.20/lb zinc, and $3.50/lb copper. Metal recoveries on the Sulphide Extension, based on the total recovery for the sulphide portion of the existing resource estimate, were 86% for gold, 76% for silver, 60% for lead, and 64% for zinc, and based on a preliminary study of similar carbonate replacement deposits were assumed to be 85% for copper. Metal recoveries on the Camino Rojo Extension, based on a preliminary metallurgical study, were 88% for gold and 92% for zinc, and based on a preliminary study of similar carbonate replacement deposits were assumed to be 85% for silver, 85% for lead and 85% for copper.

The following equations were used to calculate gold equivalence:

• Camino Rojo Sulphide AuEq = Au (g/t) + [ Ag (g/t) * 0.0106] + [ Pb (%) * 0.2460] + [ Zn (%) * 0.3499] + [ Cu (%) * 1.3555]
• Camino Rojo Extension AuEq = Au (g/t) + [ Ag (g/t) * 0.0116] + [ Pb (%) * 0.3406] + [ Zn (%) * 0.4916] + [ Cu (%) * 1.3247]

Analyzed metal equivalent calculations are reported for illustrative purposes only. The metal chosen for reporting on an equivalent basis is the one that contributes the most dollar value after accounting for the recoveries used above.
