Hole C22-187 – Gran Bestia
Hole C22-185 – Cangrejos
Lumina has decided to increase its drill program by 4,000 to 6,750 metres at Gran Bestia
Lumina Gold Corp. (TSX-V: LUM) (OTCQX: LMGDF) is pleased to announce results from thirteen drill holes at its Cangrejos project in Ecuador. Seven of the reported drill holes are from Cangrejos and six are from Gran Bestia (see Table 1). To date, eighty three drill holes have been completed, totalling approximately 27,000 metres of drilling.
Lumina is also pleased to announce increasing the total drill program at Gran Bestia by an additional 4,000 to 6,750 metres. The drill program has been designed to define the northwestern step-out area to at least an indicated category of mineral resource, so that it can be incorporated into a Pre-feasibility study mine plan. In addition to adding indicated mineral resources to the pit, the program has the potential to enhance the already excellent strip ratio at Gran Bestia.
The original planned infill and step-out drill program will be completed in mid-June and the additional drilling will take approximately one and a half months to complete.
Cangrejos Drill Hole Results
Hole C22-185 was drilled on the eastern margin of the deposit and intercepted 83m from 178m down the hole grading 1.19 g/t gold and 0.14% copper, for 1.39 g/t Au Eq., in hydrothermal breccias cutting strongly potassic and tourmaline altered quartz diorite mineralized with chalcopyrite and pyrite. Including intervals above and below this, a total of 318 metres exceeding the cut-off grade were drilled in the uppermost 410m from surface in hole C22-185 (see Table 1). This hole extends the eastern margin of the Cangrejos deposit.
Holes C22-186, C22-194 C22-195 were drilled in the southwestern quadrant of Cangrejos and all holes contain multiple intercepts reported in Table 1, including 30 metres from 54 metres down the hole grading 0.83 g/t gold and 0.08% copper, for 0.97 g/t Au Eq in hole C22-195 and 36 metres from 244 metres down the hole grading 0.75 g/t gold and 0.08% copper, for 0.88 g/t Au Eq in hole C22-186. Holes C22-184, C22-189 and C22-190 were drilled along the northern margin of the Cangrejos deposit and grades were typical of those encountered in this area, except for the previously reported vein encountered by hole C22-178 (10 metres from 148 metres down the hole grading 19.33 g/t gold with 0.12% copper for a gold equivalent 19.51 g/t).
Gran Bestia Drill Hole Results
At Gran Bestia, hole C22-187 intersected 12m grading 1.46 g/t gold with 0.12% copper for a gold equivalent of 1.68 g/t gold from surface, 60m grading 0.96 g/t gold with 0.10% copper for a gold equivalent of 1.12 g/t gold from 82m down the hole and 28m grading 1.01 g/t gold with 0.07% copper for a gold equivalent of 1.12 g/t gold from 200m.
These intervals extend the higher-grade breccia zone by approximately 50m to the northeast from those reported for hole C22-181 (see Figure 2 and Table 2). This higher grade breccia is further defined to the southwest by holes C22-170, C22-167 and C22-157. Hole C22-192, which was collared on top of the Gran Bestia ridge and angled east-northeast towards the higher grade breccia, contained six intervals but did not extend deep enough to intersect the breccia. At Gran Bestia, the corridor where the higher grade breccias occur over a northeast-southwest oriented axis, measures at least 500m in length and 200-300m in width. This irregular breccia has gradational margins and is open to northeast, to depth, and laterally in all directions except the southwest where it appears to have been closed off by drilling.
Also at Gran Bestia, holes C22-193 and C22-196 were drilled along the eastern margin of the deposit and encountered grades typical of this area. Similarly, hole C22-191 was drilled at the southern margin of the deposit and also encountered grades characteristic of the deposit limit.

|Note: Intervals in the reported holes are calculated using a cut-off of 0.2 g/t Au with maximum internal dilution of ten continuous metres. Sampling is done in consistent, continuous 2-metre intervals. The highest gold value used in the reported weighted averages is 17.65 g/t Au. In addition to the above results there were multiple intercepts of lower-grade material in the drill holes. Equivalent values were calculated using Gold equivalent values were calculated using the following prices: a gold price of US$1,500 per ounce, a copper price of US$3.00 per pound, a molybdenum price of US$7.00 per pound and a silver price of US$18.00 per ounce.|

All Lumina sample assay results have been independently monitored through a quality control / quality assurance program that includes the insertion of blind standards, blanks and pulp and reject duplicate samples. Logging and sampling are completed at Lumina’s secure facility located at the Cangrejos project. Drill core is sawn in half on site and half drill-core samples are securely transported to either Bureau Veritas Labs’ or ALS Labs’ sample preparation facilities in Quito, Ecuador. Sample pulps are sent to BV’s or ALS’ chemical labs in Lima, Peru for analysis. Gold content is determined by fire assay of a 30 gram charge with total copper content determined by four-acid digestion with ICP finish. Both labs are independent from Lumina.
Lumina is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein.
