Higher Grade Gold Zones Within Camino Rojo Sulphide Resource


VANCOUVER - Orla Mining Ltd. reported results from the oriented in-fill core drilling program on its Camino Rojo sulphide deposit, located in Zacatecas, Mexico. The drill results confirm the presence of wide, higher-grade gold zones within the sulphide mineral resource, and the Company intends to further explore the potential for open pit or underground bulk mining methods. An updated resource estimate for the sulphide portion of the deposit will be undertaken which will form the basis of a Preliminary Economic Assessment (PEA).

"We are encouraged with the results from the Camino Rojo Sulphides drill program. While the geological setting is already well understood, this new information will be meaningful as we refine the geological model and move to focus on possible development approaches," stated Jason Simpson, President and Chief Executive Officer of Orla Mining. "We are pleased that this drilling has reinforced the structural controls predicted by our geologists, and we will likely require more drilling across the orebody, ideally at this more optimal drill orientation."            

The program consisted of close-spaced drilling on three sections of the sulphide zone focusing on the extension of the Camino Rojo deposit down plunge of the planned open pit. The objective was to test the continuity of higher-grade mineralization within the 7.3 million ounces of gold in the sulphide measured and indicated mineral resource estimate (259 million tonnes at 0.88 g/t Au)[1] lying directly below the open pit currently being developed on the oxide mineral reserves. The fourteen holes completed across the sulphide zone yielded 27 significant mineralized drill intercepts[2] with a grade-by-thickness factor greater than 50 g/t by meter Au (g/t m Au), including the following 10 intercepts with a grade-by-thickness factor greater than 100 g/t by meter Au: Hole CRSX20-01: 2.38 g/t Au over 108.0m (from 445.0m to 553.0m); Hole CRSX20-01A: 2.63 g/t Au over 111.0m (from 449.5m to 560.5m); Hole CRSX20-01B: 2.51 g/t Au over 58.5m (from 428.5m to 487.0m); Hole CRSX20-01C: 2.11 g/t Au over 115.5m (from 438.0m to 553.5m); Hole CRSX20-01D: 3.04 g/t Au over 64.6m (from 515.8m to 580.4m); Hole CRSX21-04A: 4.47 g/t Au over 55.5m (from 606.0m to 661.5m); Hole CRSX21-04A: 4.95 g/t Au over 55.5m (from 676.5m to 732.0m); Hole CRSX21-04B: 2.10 g/t Au over 58.5m (from 530.0m to 588.5m); Hole CRSX21-04B: 2.27 g/t Au over 87.0m (from 609.5m to 696.5m); and Hole CRSX21-04C: 3.26 g/t Au over 44.7m (from 740.3m to 785.0m).

All assays were performed on 1.5 meter core intervals and all drill core is HQ in diameter in size. The reported composites were not subject to "capping", however a preliminary analysis suggests that only 2 out of 2,441 samples exceeded the potential capping level of 27.0 g/t - these samples averaged 36.8 g/t gold (max. 42.4 g/t) and Orla believes that applying a top cut would have a negligible effect on overall grades.
