Lumina Gold Corp. (TSX-V: LUM) (OTCQX: LMGDF) is pleased to announce additional drill results from the Cangrejos and Gran Bestia resource in-fill, step-out and exploration program. These fifteen holes (C19-125 to 139) represent approximately 6,430 metres of drilling. The results include six holes from the Gran Bestia Deposit, four from the Cangrejos Deposit and five from the Corridor Zone.
Drilling of the main Cangrejos Deposit has concluded since Lumina’s last news release with two in-fill holes (C19-127 and 129) and three step-out holes (C19-134, 138, and 140). The step-out holes tested the depth extension of an area of high-grade rock chip and trench samples in the northwestern sector previously mentioned in the news release dated June 26, 2019. Results from two of the three step-out holes are reported here, while assays from the third remain pending. Hole C19-134 cut a long interval at the average resource grade, while C19-138 hit an exceptional zone from surface of 302 metres grading 1.22 g/t gold and 0.14% copper.
Although Lumina has finished the current in-fill program across both deposits for the resource update, it has elected to keep two of the four rigs at site to drill the northern ridgeline area of Gran Bestia. The ridgeline is still open to the northwest, where step out holes are targeting the longest intercepts drilled to date. Once this zone has been approximately delineated by drilling, the program will be paused and the Company will complete an updated resource estimate incorporating the last two years’ worth of drilling. Lumina expects the revised estimate to be completed by November 2019.
Gran Bestia in-fill holes C19-128, 131, 133 and 139 all cut long intervals of moderate-grade mineralization from surface. The margins of the Gran Bestia Deposit may have been reached to the south with hole C19-125 and east with hole C19-135. Although mineralization continues to the east, it begins to narrow and drops in grade.
Drilling in the Corridor Zone has concluded. Of note, resource in-fill hole C19-129, collared on the northwestern flank of the Cangrejos Deposit, was extended well beyond the assumed limits of the main resource. While the hole hit mineralization of good grade related to the Cangrejos Deposit higher in the hole, at depth it also cut 104 metres averaging 0.58 g/t gold and 0.15% copper likely forming part of the Corridor Zone. Numerous other drill holes also cut mineralization in the Corridor Zone, holes C19-126, 130, 132, 136, and 137. Modelling of the mineralization controls within the Corridor Zone is ongoing.

Drill Intercept Summary
|Hole Number||Deposit||From||To||Interval||Au Grade||Cu Grade||Azimuth||Dip||Type|
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 8.43 g/t Au. In addition to the above results there were multiple intercepts of lower-grade material in the drill holes.
All Lumina sample assay results have been independently monitored through a quality control / quality assurance program including 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 ALS Lab’s sample preparation facility in Quito, Ecuador. Sample pulps are sent to 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. ALS Labs is 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.
Leo Hathaway, P.Geo., Senior Vice President of Lumina and the Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects for the Cangrejos Project has reviewed, verified and approved the contents of this news release.
