Orla Intersects 158.7 Metres Grading 0.62 g/t Au and 0.62% Cu at the Cerro Quema Project, Panama

30.11.2017  |  GlobeNewswire

VANCOUVER, British Columbia, Nov. 30, 2017 (GLOBE NEWSWIRE) -- Orla Mining Ltd. (TSX VENTURE:OLA) ("Orla" or the "Company") is pleased to provide an update on drilling at its wholly owned Cerro Quema project in Panama, and report continued success at the Caballito copper-gold zone. We highlight in particular diamond drill hole CQDH17-136 which intersected 158.7 metres grading 0.62 g/t Au and 0.62% Cu from 50.6 to 209.3 m depth. Lower grade mineralization below this averaged 0.15 g/t Au and 0.17% Cu over 79.9 meters from 209.3 to 289.2 metres. A separate upper intersection graded 0.37 g/t Au and 2.24% Cu over 6.9 metres from 31.1 to 38.0 metres.

In the main 158.7 metre intersection, gold grades are fairly uniform throughout. Copper is more variable, ranging from 0.08 to 3.64%. The best copper intercept was 29.5m @ 1.31% Cu and 0.53 g/t Au from 101.0 to 130.5 metres. As with other holes in the Caballito zone, arsenic is at a much lower ratio to copper than in holes further to the north.

CQDH17-136 was drilled at -600. A second hole, CQDH17-140, was drilled at -900 from the same pad. This hole had a narrow section of similar Cu-Au mineralization that averaged 0.29 g/t Au and 0.47% Cu from 160.4 to 172.3 metres. An upper intersection of 2.4m @ 0.37 g/t Au and 1.13% Cu from 103.0 to 105.4 metres had high associated arsenic and thus may be unrelated to what is considered the Caballito Cu-Au Zone.

CQDH17-136 was drilled 100 metres to the northwest of previously reported CQDH-17-116 which intersected 49.0m @ 0.50 g/t Au and 1.39% Cu and 55.8m @ 0.28 g/t Au and 1.99% Cu in two intercepts separated by 28.7m of low grade material. (See News Release dated Sept. 15, 2017). Results from holes CQDH17-116, 136 and 140 suggest a north-north-west control to mineralization. Wide Cu-Au intercepts in holes CQDH17-127 and 132 located to the east of CQDH17-116 released on November 14, 2017 indicate at least some horizontal control to mineralization in that area. Due to the wide spacing of current holes, the geometry and thus true width, of mineralization is uncertain and will require continued drilling to determine. The potential extent of mineralization is also unknown. A hole a further 100 metres to the northwest of CQDH17-136 was recently completed and a hole to test for mineralization to depth closer to CQDH17-116 is in progress.

Marc Prefontaine, Orla CEO noted, “The intersection in CQDH-17-136 really shows the potential of the Caballito Cu-Au zone. We have a lot of work to do to figure out the geology of the area, but we now have several good intercepts. The extent of mineralization horizontally and vertically is unknown. This is a very exciting target and we plan to move another drill into this area early in 2018.”

In addition to the drill working in the Caballito area, a second rig has been drilling in the Quemita area testing for potential extensions to depth and along strike to the reserves contained in a proposed pit outlined in the project Pre-Feasibility Study (PFS). Results from four holes in Quemita are reported herein. Hole CQDH17-137 was drilled quite far below the pit and did not intersect oxide. Holes CQDH17-138, 139 and 141 were drilled on the western margin and to the west of the PFS pit. Oxide intersections of 16.1m @ 0.49 g/t Au in CQDH17-138 and 48.2m @ 0.20 g/t Au in CQDH17-141 show potential for some increase to resources in this area. This drill was recently moved to test prospective targets to the north and downhill of the Quemita resource. Once all results from the Quemita drilling have been received, a new geological model will be created and the need for any additional drilling determined.

A third drill is operating to acquire material for additional metallurgical column test work. Testing will focus on the potential for a larger crush size than in the current PFS model or placing Run of Mine material onto the proposed heap leach pad.

Quality Control Protocols

All gold results 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 and copper, using an Aqua Regia (ME-ICP41) method at ALS Laboratories in Peru. Samples with copper values in excess of 1% by ICP analysis are re-run with Cu AA46 aqua regia and atomic absorption analysis. Drill program design, Quality Assurance/Quality Control and interpretation of results are performed by qualified persons employing a Quality Assurance/Quality Control program consistent with NI 43-101 and industry best practices. Standards, blanks and duplicates are included approximately one every 25 samples for Quality Assurance/Quality Control purposes by the Company as well as the lab. Approximately 5% of sample pulps are sent to a secondary laboratory for check assays. The HQ diameter core is halved with a diamond saw.
