VANCOUVER, BC , Oct. 31, 2024 /CNW/ - Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) ("Orla" or the "Company") is pleased to provide an update on its exploration at the South Railroad Project ("South Railroad" or the "Project").

Highlights:

  • Significant gold intercepts indicate strong potential to expand oxide gold mineralization beyond the projected open pit boundaries and extend the projected mine life at the Pinion and Dark Star deposits. Higher grade sulphide gold mineralization is also being encountered.

  • The ongoing drilling program focuses on defining new oxide mineralization, expanding the resource base by targeting open zones along key structures, and testing multiple targets across the property, including selective sulphide target testing.

  • Orla has now integrated the recently acquired Pony Creek property and the larger, enhanced land package will now be referred to as the "South Carlin Complex". This area includes the South Railroad Project which hosts multiple mineralized zones and exploration targets along a 30- kilometre strike length on the Carlin Trend covering approximately 25,000 hectares.

  • Significant permitting progress at the South Railroad Project has been made at the federal and state levels to advance the posting of the Notice of Intent ("NOI") in early 2025.

"Follow-up drilling at the South Railroad project continues to highlight the potential for mineralization extensions along key mineralized structures beyond the projected open pits. Drilling remains ongoing at these high-priority, development-stage targets, as well as across other prospective areas across the broader land package, creating exposure to potential new discoveries in our South Carlin Complex."

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

Dark Star Deposit – Extending oxide gold mineralization 75m down dip and 85m along strike

Recent follow-up drilling has extended oxide gold mineralization 75 metres down dip and 85 metres along strike beyond 2023 results (Figure ,3). These recent results are highly encouraging, suggesting the potential to grow the Dark Star resource beyond the currently projected open pits. In addition to recent oxide mineralization, significant sulphide mineralization has also been intercepted suggesting the mineralized system remains open at depth. Drilling results in the "Saddle" area between the Dark Star Main and North deposits, suggests potential for additional gold mineralization in this area. Follow-up drilling has been completed and assays are pending.

Pinion Deposit – Expanding oxide gold mineralization 150m along strike

Recent drilling at the Pinion deposit followed-up on positive results from 2023 targeting the southeast extension of gold mineralization (see news release dated March 7, 2024). The new assay results from the 2024 drilling program targeted an area 150-200 metres southeast of the projected open pit, confirmed continuity and enhanced grade between historical drill holes. These new intercepts returned wider intervals of gold mineralization than nearby historical drill holes. Historical and recent drilling suggests gold mineralization remains open outside the projected open pit at Pinion, extending 500 metres to the southeast.

2024 Exploration Drill Program

The 2024 exploration program at South Carlin Complex plans for approximately 20,000 metres of drilling, with around half of this drilling focusing on expanding mineralization at the South Railroad Project'sDark Star and Pinion deposits and testing extensions to grow satellite deposit resources. The remaining drill metres will target additional exploration prospects across the South Carlin Complex. As of September 30th, approximately 13,000 metres of the planned drilling had been completed. Drilling activities are expected to continue through the end of the season, with further drilling planned at Dark Star and other satellite deposits in the southern part of the property. Year to date exploration spending at the South Carlin Complex total $10.3 million as part of the $14.0 million guidance. Orla is currently operating 10 exploration drill rigs across its portfolio, with the aim to expand resources and make new discoveries.

South Railroad Project Permitting Update

The South Railroad Project, situated on federal land, is currently advancing under the guidance of the US Bureau of Land Management (BLM) in accordance with the National Environmental Policy Act (NEPA) for permitting. Orla is finalizing 20 Supplemental Environmental Reports (SERs) required by the BLM prior to issuing a Notice of Intent (NOI). To date, 15 reports have been reviewed by the BLM and cooperating agencies, and Orla's consultants are completing the final five with feedback incorporated. The Company aims to finalize all SERs by the end of 2024.

The NOI is expected to be published in early 2025, with the Company targeting a Record of Decision (final permitting decision) by mid-2026. Following this approval, construction on the South Railroad Project would commence, with first gold production anticipated in 2027.

At the state level, the Company has received Class I and II Air Operating Permits. Applications have been prepared for the Water Pollution Control Permit and the National Pollutant Discharge Elimination System (NPDES) discharge permit, which will be submitted after the NOI in 2025.

The Engineering, Procurement, and Construction Management (EPCM) contract is set to be awarded later this year. Basic and detailed engineering will proceed in 2025 and 2026 to align with construction following the Record of Decision. Long-lead equipment will be identified, with purchase orders potentially beginning in 2025.

Qualified Persons Statement

The scientific and technical information in this news release with respect to the 2024 drilling programs has been reviewed and approved by Mr. Sylvain Guerard, P Geo., SVP Exploration of the Company, and with respect to permitting matters has been reviewed and approved by Mr. Andrew Cormier, Chief Operating Officer of the Company, each of whom is a Qualified Person as defined under the definitions of National Instrument 43-101 ("NI 43-101").

To verify the information related to the 2024 drilling programs at the South Railroad 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 –2024 Drill Program

Gold results from 2024 drillholes at the South Railroad Project were obtained by fire assay fusion and absorption emission finish (FA430) at Bureau Veritas Mineral Laboratories in Sparks, Nevada, USA. Over limit gold assays were determined using fire assay fusion with gravimetric finish (FA530). Gold cyanide extraction was determined using a 1-hour cyanide leach (CN403) conducted in either Sparks, Nevada, or Hermosillo, Mexico. All other elements were determined by 4-acid dissolution with ICP-OES+MS method (MA200).

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. Certified reference material (standards), blank, or rig duplicate were inserted approximately every tenth sample for Quality Assurance/Quality Control purposes by the Company. Bureau Veritas Mineral 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 the South Railroad Project.
