The current drill program is comprised of wide-spaced holes testing a number of concepts that could add significant value to the project in the near-term. All holes were drilled in the general area of the Quemita Zone, which is one of two zones that contain the 488,000 ounce Cerro Quema oxide gold reserve (19.7 mT at 0.77 g/t Au - see 2014 N43-101 Technical Report on Orla website). Targets include areas of alteration that may host undiscovered gold zones in oxidized material, potential extensions to the pits outlined in the 2014 pre-feasibility study (PFS) and possible upgrades to the resources within the PFS pits based on better geological modelling of the higher grade parts of the deposits plus a re-interpretation of the base of the oxide zone.
The early drilling has highlighted the potential for additional mineral zones to the north and down-slope of the Quemita reserve. Six holes in this area intersected strong high-sulphidation style alteration. The best gold grades were encountered in holes CQDH17-069 (47.8 m at 0.47 g/t Au) and 070 (52.4 m at 0.49 g/t Au) which were drilled in opposite directions from a drill pad 400 metres northeast of the proposed Quemita pit. Gold grades are associated with hydrothermal brecciation and vuggy silica indicating proximity to a center of hydrothermal activity. Grades start at surface and the entire intercepts, as well as material below, are oxidized. Two holes drilled from a pad 600 m to the west-southwest of these holes, CQDH17-066 and 067, intersected well altered and oxidized material, including zones with vuggy silica. Gold results were anomalous, but low. The area in between these four holes, and extending in both directions past them, has intermittent outcrops of strongly altered rock. A number of follow-up holes are planned in this large prospective area.
Holes CQDH17-75 and 76, drilled in the middle of the existing Quemita resource/reserve, returned excellent results of 42.3 m at 3.50 g/t Au and 63.5 m at 1.37 g/t Au (including a section that averaged 3.27 g/t Au over 16.5 m at the top of the hole). Most of the previous drill holes at Quemita were vertical and largely reverse circulation (RC). The new angled core holes confirm there is a surface blanket of higher grade material which is interpreted to be due to weathering related enrichment. This blanket is underlain by more vertically controlled primary gold mineralization. Core holes will be important in developing a new geological model for the deposit which will used for a new resource estimate and metallurgical recovery analysis.
CQDH17-068 intersected 21.3 m averaging 1.35 g/t Au 35 metres west of the proposed Quemita pit. This near-surface oxide intercept highlights the potential for extending the Quemita resource to the west. CQDH17-072 had two gold intercepts. The upper (13.6 m at 0.69 g/t) is within the proposed pit while the lower one (44.2 m at 0.30 g/t Au) indicates potential to expand mineralization to the south. CQDH17-065 also had a narrow intersection (7.1 m at 0.48g/t Au) to the south of the existing Quemita proposed pit.
CQDH17-071 intersected 34.8m at 2.42 g/t Au in the eastern part of the proposed Quemita pit. Like other holes, this intersection starts at surface. Drill holes such as this will be used to build a better geological model of the high grade parts of the deposit.
The final holes with assays returned, CQD17-073 and 074, were drilled at depth below and to the north of holes 069 and 070. They intersected only anomalous gold values or narrow zones of low grade indicating that the roots to the higher grade mineralization in 069 and 070 are faulted off or are further to the south.
Marc Prefontaine, CEO of Orla, commented, "It is very encouraging that our exploration team has been successful in confirming potential so early in their exploration efforts. We are developing a good understanding of the geological controls to mineralization. Three concepts that could provide near-term additions to the project economics were tested: Possible new zones of oxide proximal to the pits outlined in the 2014 PFS; extensions to the PFS pits; and opportunities for higher grades within the PFS pits. The first 12 holes have provided positive support for all three. With continued drilling, in conjunction with geology and new geophysical surveys, we look forward to building the gold resources on the project. Continued success in the areas currently being drilled would add material which could be incorporated into the current Pre-Feasibility development plan and potentially add significant value to the project. Mapping, sampling and geophysics is also progressing well in an effort to advance new targets over the large land package to the drill stage".
Three man-portable diamond drill rigs continue working on the project. A budget for up to 25,000 metres of drilling in 2017 has been approved by the Orla board of directors.
Quality Control Protocols
Core is drilled HQ diameter. Core is cut in half by saw, with one half sent for analysis. All gold results were determined 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 Lima, Peru. 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 every 25 samples for Quality Assurance/Quality Control purposes by the Company as well as the laboratory. Approximately 5% of sample pulps are sent to secondary laboratories for check assays.
