Targeting Additional Near Mine Oxide Ounces

Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) is pleased to provide an update on its near-pit exploration activities at Camino Rojo completed in the second half of 2023.

2023 Exploration Highlights: Camino Rojo Oxides (Mexico)

In 2023, Orla completed 6,500 metres of drilling near the Camino Rojo Oxide Mine in Mexico to define additional oxide mineralization near the open pit. This near-pit exploration included 2,500 metres of drilling to confirm oxide gold mineralization on the Fresnillo plc property (the “Layback Area”), located immediately north of and adjacent to the Camino Rojo Oxide Mine open pit, and 4,000 metres of drilling targeting the extension of oxide gold mineralization hosted by key structures controlling deeper levels of oxide mineralization within and beyond the currently designed oxide open pit (Figure 1). An updated resource is planned for the first half of 2024, incorporating, for the first-time, mineral resources in the Layback Area.

“Our 2023 near-mine exploration validated near-surface oxide gold in the Layback Area and uncovered oxide expansion potential near the edge of the Camino Rojo Oxide Mine. The positive results from our near-mine oxide drilling program highlight the opportunity to replace a portion of the depleted ounces at the mine by incorporating incremental near-mine oxide material. These positive results pave the way for the 2024 near-mine drill program.”

Sylvain Guerard, Orla’s Senior Vice President, Exploration

The Layback Area drilling confirmed and delineated gold mineralization immediately north of and adjacent to the Camino Rojo Oxide Mine open pit (Figure 2). Results from the Layback Area drill program confirmed historical drill results and the continuity of oxide hosted gold mineralization across the property boundary.

Highlights of the Layback Area drill program:

In near-pit oxide extension drilling, Orla’s exploration approach was to test along strike and down dip of key structures controlling oxidation to define additional oxide gold mineralization. Results from this program identified significant structurally controlled oxide mineralization up to 50 metres below (e.g., CROX23-08, 67.1m at 1.16 g/t incl. 58.0m at 1.32 g/t Au, Figure 3) and up to 15 m southeast (e.g., CROX23-17, 23.5m at 0.45 g/t Au, Figure 4) of the current ultimate oxide pit boundaries. Notably, the shallow oxide material intersected southeast of the current pit extents is considered to have the highest potential for driving a pit expansion. Follow-up drilling of the oxide mineralization southeast of the pit wall is planned for 2024.

Highlights of the near-pit extension drill program include:

Qualified Persons Statement

The scientific and technical information in this news release has been reviewed and approved by Mr. Sylvain Guerard, P Geo., SVP Exploration of the Company, who is the Qualified Person as defined under the definitions of National Instrument 43-101.

To verify the information related to the 2023 drilling program at the Camino Rojo property, Mr. Guerard has visited the property in the past year; discussed logging, sampling, and sample shipping processes with responsible site staff; discussed and reviewed assay and QA/QC results with responsible personnel; and reviewed supporting documentation, including drill hole location and orientation and significant assay interval calculations.

Quality Assurance / Quality Control –2023 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 Laboratories is 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.

For additional information on the Company’s previously reported drill results referenced in this news release, see the Company’s news releases dated September 12, 2022 (Orla Mining Advances Exploration & Growth Pipeline) and January 31, 2023 (Orla Mining Continues to Intersect Wide, Higher-Grade Sulphide Zones and Expose Deeper Potential at Camino Rojo, Mexico).

Historical drill results at Camino Rojo were completed by Goldcorp. Inc. 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, and that the Goldcorp QA/QC program met or exceeded industry standards. See the Camino Rojo Report (as defined below) for additional information.
