Orla Mining Drills Oxide Mineralization Outside Projected Open Pits at South Railroad Project in Nevada

Pinion and Dark Star deposits through new oxide intersections in step-out drilling:- Pinion: 0.72 g/t Au over 112.7 metres (oxide)
Dark Star : 3.53 g/t Au over 36.6 metres (oxide)
- Successful infilling and metallurgical drilling with confirmation of modeled grade, continuity of mineralization, via infill drill program.
- Intersection includes 2.20 g/t Au over 163.1 metres (oxide) and 2.50 g/t Au over 88.1 metres (oxide).

In 2023, Orla extended oxide-hosted gold mineralization at the
At the Pinion deposit, a review of available geological data suggested gold mineralization may be continuous in the southeastern part of the deposit over the Pinion SE target area, where faulting had been previously interpreted as limiting or displacing extension of the mineralization. To test the continuity of gold mineralization, three drill holes totaling 822 metres were completed. All three drillholes intercepted significant oxide-hosted gold mineralization, including 0.72 g/t Au over 112.7 metres (oxide) confirming the continuity of gold mineralization to the southeast without fault displacement interference (Figure 2). These results, combined with historical drill intersections, indicate geological continuity and suggests gold mineralization extends to at least 350 metres outside of the projected open pit.
Significant results from drilling at Pinion:

Exploration drilling at the
Drillhole DR23-01 targeted the potential extension of high-grade mineralization east of the currently designed open pit limit, returning wider and higher-grade oxide hosted gold mineralization than nearby drill holes and average resources grade, including 3.53 g/t Au over 36.6 metres (oxide), 5.23 g/t Au over 19.8 metres approximately 50 metres outside of the projected open pit limit (Figure 3). The exceptional results from this extension drilling suggests the potential to define additional oxide mineralization, possibly associated with a previously unknown feeder structure for the

One reverse circulation and one core drillhole were completed within the northern pit at the
The reverse circulation hole, DR23-02, was drilled to confirm continuity of high-grade Au in oxide mineralization at the base of the designed open pit. Highly positive assay results, 2.20 g/t Au over163.1 metres (oxide), incl. 3.97 g/t Au over 30.5 metres, confirmed the modeled grade, limits of gold mineralization, and continuity of high-grade mineralization at the base of the designed open pit.
The core drillhole, DSC23-02, was drilled to provide material for run-of-mine column test work. The strong assay results, 2.50 g/t Au over 88.1 metres (oxide), incl. 5.69 g/t Au over 30.5 metres1, from hole DSC23-02 are consistent with historical drill data and the mineral resource estimate block model. The run-of-mine column test work is expected to be undertaken in 2024.

Hole DSC23-02 was chip sampled, rather than quarter-cut, to preserve the maximum amount of core for metallurgical test work. All remaining core from the reported mineralized interval is expected to be consumed during the metallurgical testing. |
