- 1.17 g/t gold equivalent over 134 metres from surface at Gran Bestia
- Extends existing higher-grade breccia area
- Extended mineralization laterally outside the PEA ultimate pit to the northwest by approximately 180 metres
- Including 0.49 g/t gold equivalent over 170 metres
- Open laterally and to depth
Based on results from hole C22-160, Lumina is drilling an additional step-out hole at Gran Bestia
- If more positive results are received, Lumina will advance plans for a more substantive step-out drilling program
- Hole C22-160, has shown potential to add to the mineral resource and change the Gran Bestia pit configuration, which could affect how much of the existing mineral resource is brought into a mine plan
Vancouver, British Columbia - Lumina Gold Corp. (TSXV: LUM) (OTCQX: LMGDF) (the “Company” or “Lumina”) is pleased to announce results from twelve drill holes at its Cangrejos project (the “Project”) in Ecuador. Seven of the reported drill holes are from Cangrejos and five are from Gran Bestia (see Table 1). To date, thirty-six drill holes have been completed and six drill holes are in progress, totalling 15,055 metres of drilling. Lumina currently has six rigs operating and will be drilling with eight rigs in April.
At Gran Bestia, hole C22-167 intercepted 134 metres from surface grading 1.01 g/t gold, 0.10% copper, for a gold equivalent grade of 1.17 g/t Au Eq. In this area, zones of brecciation tend to be of higher grade. This interval was breccia dominated and extends the existing higher grade breccia body by at least 100m to the southeast. Additional drilling at Gran Bestia is expected to further refine the Company’s understanding of the geometry of this shallow zone of high grade mineralization.
Also, at Gran Bestia, approximately 450m northwest from hole C22-167, Lumina drilled an aggressive step-out hole, C22-160, into an area where the deposit is open to the northwest and to depth (see Figures 1 and 2). The intervals in this hole extend the known mineralization laterally, to the northwest. The area remains open laterally and to depth and warrants further drilling. The significance of hole C22-160 is illustrated in Figure 2 as it extends mineralization above the base case cut-off grade (0.30 g/t Au Eq) approximately 120m laterally from the mineral resource block model limit and approximately 180m laterally from the northwest pit limit. These measurements are compared to the 2020 Preliminary Economic Assessment (“PEA”) mineral resource and mine plan, respectively. The potential extension of the resource in this direction could improve future economic studies.
Follow-up drilling along the northwestern flank of the deposit, starting with one additional hole in April, is planned to fully understand the potential of this extension. The additional mineralized material could potentially change the Gran Bestia pit configuration and result in the incorporation of existing mineral resources that were not included in the PEA mine plan (see Figure 2).
Three infill holes, C22-161, C22-164 and C22-165 were also drilled at Gran Bestia and all encountered at least 100m intercepts at typical grades for the deposit.
At Cangrejos, hole C22-154 was drilled in the central part of the deposit and intercepted 214m from 246m down the hole grading 0.52 g/t gold and 0.11% copper, for 0.70 g/t Au Eq. Hole C22-152 was drilled approximately 300m to the east-northeast of C22-154, close to the northeastern limit of the deposit, and intersected 156m from 4m down the hole grading 0.47 g/t gold and 0.12% copper, for 0.65 g/t Au Eq.
Holes C22-159 and C22-166 were drilled in the southwestern quadrant of the Cangrejos deposit to further delineate the extent of a poorly mineralized dike that had been included in previous deposit modelling. Both holes were collared in this dike, were inclined to the northwest and established its northwest contact.
Hole C22-162 was drilled in the southwest quadrant of Cangrejos, hole C22-163 was drilled in the central area, and C22-168 was drilled in the northwest quadrant of the deposit. These three holes all returned intervals with grades typical for the Cangrejos deposit.

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 12.50 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 ("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.
