Lumina Gold Corp. Aug 17, 2022, 07:00 ET
Highlights include:
Completed the 2021/2022 drill campaign with over 36,000 metres drilling.
Gran Bestia
- Long intercepts in seven ridge holes expected to add mineral resources, open in all directions
- C22-225: 0.76 g/t gold equivalent over 287 metres
- C22-214: 0.72 g/t gold equivalent over 126 metres
Cangrejos
- C22-226: 0.70 g/t gold equivalent over 222 metres – open to southwest and to depth
- C22-222: 1.23 g/t gold equivalent over 36 metres – open to east
VANCOUVER, BC, Aug. 17, 2022 /CNW/ - Lumina Gold Corp. (TSXV: LUM) (OTCQX: LMGDF) (the "Company" or "Lumina") is pleased to announce results from twenty-five drill holes at its Cangrejos Project (the "Project") in Ecuador. Seventeen of the reported drill holes are from Cangrejos and eight are from Gran Bestia (see Table 1). During the 2021/2022 drill program, 107 drill holes have been completed, totalling 36,027 metres of resource definition and geotechnical drilling. The drill program is now complete, and all drill rigs have been demobilised from site. Results from two holes at Cangrejos and fifteen at Gran Bestia are pending; including geotechnical holes.

Marshall Koval, CEO, President and Director commented: "I would like to thank our geological team for completing a well executed large-scale program on time. The drilling campaign appears to have delivered exactly what we set out to do, infill the US$1,100 gold constrained pits that formed the basis of the 2020 PEA, while also completing step-out drilling that should enhance the resource size and overall attractiveness of the Project."
Work on the Pre-Feasibility Study ("PFS"), expected to be completed in Q2 2023, is continuing. With the drilling now concluded, PFS resource estimation work has been initiated. The supporting geologic and structural models are near completion. Pit slope geotechnical testing and hydrogeologic characterization are also near completion for development of pit slope design recommendations. In addition, metallurgical testing of ~4,700 kgs of drill core is underway at Laboratorio Plenge in Lima. Ongoing field work includes site characterization for project infrastructure and baseline environmental studies.
Cangrejos Drill Hole Results
Results from nine drill holes from the southwestern quadrant of Cangrejos are reported (C22-211, C22-213, C22-217, 22-221, C22-223, C22-224, C22-226, C22-230, and C22-231). Results from these holes are highlighted by hole C22-226 that intersected 221.6 metres from surface to the end of the hole grading 0.57 g/t gold and 0.08% copper, for 0.70 g/t Au Eq. This hole is open to the southwest and leaves the deposit open in this direction and to depth. Results from the other eight holes in this quadrant were typical of those returned from the edges of the deposit.
Results from eight drill holes from the remaining northern, central and southeastern parts of Cangrejos (C22-208, C22-210, C22-215, C22-216, C22-219, C22-222, C22-227 and C22-229), are also typical of the deposit limits. However, hole C22-222 contained 36 metres from 164m grading 1.14 g/t gold and 0.06% copper, for 1.23 g/t Au Eq. This interval is open to the east and corresponds to those higher-grade zones reported from other areas of the Cangrejos periphery.
Gran Bestia Drill Hole Results
Seven of the eight holes drilled at Gran Bestia were collared on the ridge crest and drilled down into the ridge to potentially add resources and lower the strip ratio, as this mostly previously uncategorized material formed the high wall of the Gran Bestia PEA pit. All of these holes returned long intervals above the previous mineral resource cut-off grade and are expected to add significantly to the Gran Bestia mineral resource estimate for use in the upcoming PFS. This drilling leaves mineralization in this area open in all directions, including to depth. Of particular note is hole C22-225, that intersected 287m grading 0.59 g/t gold with 0.12% copper for a gold equivalent of 0.76 g/t gold from 270 metres and remains open to depth, as well as six other reported intervals (see Table 1); and hole C22-214, that intersected 126m grading 0.62 g/t gold with 0.07% copper for a gold equivalent of 0.72 g/t gold from 144 metres down the hole, as well as two other reported intervals (see Table 1). The eighth hole, C22-207 at Gran Bestia was drilled at the southeastern limit of the pit towards the Cangrejos deposit and contained a 56-metre interval from 28m grading 1.11 g/t gold and 0.04% copper, for 1.18 g/t Au Eq, leaving the deposit open in this direction.

| 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 22.9 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 calculations assume 100% recovery of all quoted metals and the following prices were used: 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.

Quality Assurance
All Lumina sample assay results have been independently monitored through a quality control / quality assurance ("QA/QC") 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' (BV) or ALS Labs' ("ALS") 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.
