VANCOUVER, Feb. 22, 2024 - Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) ("Orla" or the "Company") is pleased to provide an update on its exploration activities on the extension of the Camino Rojo deposit ("Camino Rojo Extension") in the second half of 2023. These recent exploration results emphasize that the Camino Rojo deposit remains open and has substantial upside potential.

Camino Rojo Extension (Mexico) Summary

Historical and recent exploration drilling targeted lower stratigraphy, beneath the existing resources. In 2023, a drill section was completed 450 metres down-plunge from the current mineral resources and revealed significant intersections of high-grade polymetallic (Au-Ag-Zn) semi-massive to massive replacement-style mineralization (Figure 1). Recent drilling shows that the Camino Rojo mineral system extends beyond the current mineral resource envelope, presenting a considerable opportunity for resource expansion.

  • 2023 Program: The 2023 Camino Rojo Extension drill program involved extending selected infill drillholes beyond the currently defined mineral resources and completing a down-plunge drill section to explore the distal extension into lower stratigraphy; 2,607 metres of drilling across four drill holes. Drill results reported in this press release have returned mineralized intercepts up to 450 metres down plunge of the existing open pit mineral resource boundaries.
  • Initial Metallurgy: The initial carbon-in-leach (CIL) bottle roll testing within the Camino Rojo Extension on material from CRSX-22-07 and CRSX-22-08C resulted in impressive gold recoveries between 81-96%. Flotation testing on the CRSX-22-07 material produced a gold concentrate with 85-88% gold recovery and a zinc concentrate with zinc grades of 52% and over 85% zinc recovery, for the polymetallic replacement-style mineralization.
  • 2024 Program: The Company plans to complete a 30,000-metre drill program in 2024 with two objectives: 1) to infill the down-plunge geometry, continuity, and endowment potential of mineralization along the projection of the Dike Zone, and 2) to step out broadly and further assess the extensive upside potential of this open mineralized system.

"The recent drilling results have added a new dimension to our near-mine exploration program, unveiling an exciting new mineralization style in previously disregarded host rocks. With promising initial metallurgical results and substantial upside extension potential, we are committed to driving Orla's 2024 exploration efforts towards expansion drilling as we look to unlock the full potential of the growing Camino Rojo deposit."

- Sylvain Guerard, Orla's Senior Vice President, Exploration

New polymetallic sulphide replacement style mineralization

Orla Mining has confirmed and encountered sulphide mineralization extending beyond the established open pit mineral resource boundaries at Camino Rojo (Table 1). This drilling and mineralization is building on an updated geological model and the success of the previously reported CRSX22-15C hole drilled 200 metres down-plunge from the existing resources (see Table 2 and the Company's June 22, 2023 news release).

The impressive intercepts, both historical and recent, justified the execution of a new drill section in 2023, targeting 450 metres down-plunge from the existing resources, along the dike zone structure (Figures 2-4). This significant step-out drilling initiative consisted of drilling 2,400 metres, targeting the area around the positive historical intercept in hole CR12-366D (15.7 g/t Au, 29.0 g/t Ag, 0.73% Zn, 0.10 % Pb, 0.08% Cu (19.6 g/t AuEq) over 4.5 metres. This new drill section confirmed the presence of significant polymetallic semi-massive to massive sulphide mineralization (Figure 4). Significant results from this drill section are shown in Table 1.

Positive Initial Metallurgical Results

Orla completed an initial metallurgical testing program in 2023, using drill core material from holes CRSX22-07 and CRSX22-08C (see Table 2) which intersected polymetallic replacement-style mineralization during the 2022 program. The metallurgical results on material from CRSX-22-07 and CRSX-22-08C were positive with high gold recovery reported in both CIL bottle roll tests between 81-96% and rougher flotation on the CRSX-22-07 material produced a gold concentrate with 85-88% gold recovery. Open-circuit zinc cleaner tests on material from CRSX-22-07 produced a zinc concentrate with zinc grades of 52% and over 85% zinc recovery. These results suggest this new style of mineralization may be amenable to both standard cyanide processing and flotation. Orla plans to further explore these promising results through additional metallurgical test work in 2024.

Background

Historical context: Wide-spaced drill intersections of polymetallic (Au-Ag-Zn) replacement-style mineralization were encountered in historical holes beneath the Caracol formation, but the relationship between these intersections and the Camino Rojo sulphides deposit was uncertain, partly due to the lack of a comprehensive geological model for the deeper part of the mineralized system.

2022 program: Part of the 2022 infill program targeted deeper parts of the mineral resource hosted within the upper Indidura formation. This drilling intersecting polymetallic (Au-Ag-Zn) mineralization, similar to the wide-spaced historical intercepts, up to 50 metres below the contact between Caracol and Indidura formations. These results provided confidence that the mineralized system likely continued lower.

2024 Drill Program

The 2024 Camino Rojo Extension drill program commenced on January 9th with six drill rigs currently operational. This program (Figure 5) is comprised of 15,000 metres dedicated to the dike extension target, focusing on the 500-metre spanning between the current mineral resource and the CRSX23-22 series of drill holes. An additional 15,000 metres are allocated to testing open mineralized trends and historical high-grade intersections, aiming to assess the broader potential of the growing Camino Rojo Deposit.

Full drill results are available in the Appendix to this news release and are available at www.orlamining.com.

All metres reported above are down-hole intervals, with true width estimates ranging from 72-88% of the reported interval. See Table 1 in the Appendix to this news release for estimated true widths of individual composites. A standard sampling length of 1.5m is used with a minimum of 0.5m when required based on geologic contacts. All drill core is HQ diameter. The reported composites were not subject to "capping," however a preliminary analysis suggests that only 1 out of 972 samples from the reported holes exceeded the potential capping level of 27.0 g/t Au. This sample assayed 28.6 g/t Au. Orla believes that applying a top cut would have a negligible effect on overall grades. Composites for the sulphide drilling were calculated using 1 g/t Au cut-off grade and maximum 6 metres consecutive waste.

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 gold, 100ppm silver 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 silver and 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.

The initial metallurgical testing on the Camino Rojo Extension was completed by Blue Coast Research Ltd. ("Blue Coast"). Blue Coast is independent of the Company and employs an internal quality assurance-quality control program consistent with NI 43-101 and industry best practice.

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 Corporation 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.
