Lumina Gold Corp. (Lumina) has announced additional drill results from the Cangrejos and Gran Bestia resource infill, step-out and depth extension programme. These three holes (C19-104 to C19-106) represent approximately 1400 m of drilling. The results include two holes from the Gran Bestia deposit and one from the Cangrejos deposit.
Hole C19-105 at Gran Bestia stepped out on the northern edge of the anomaly and remained in mineralisation from its collar to termination at 626 m depth, making it the longest continuous interval of mineralisation ever cut at the Cangrejos project. The hole ended in mineralisation and leaves the Gran Bestia deposit open to the north for expansion and further discovery.
Hole C19-104 at Gran Bestia was drilled to the southeast along the southern margin of the Gran Bestia surface geochemical anomaly to determine the extent of mineralisation and breccia in that direction. The hole stayed in lower-grade mineralisation for 148 m before exiting the system.
Hole C19-106 at Cangrejos was drilled to the northwest along the northern boundary of the main Cangrejos resource and cut two significant intervals of mineralisation to a depth of 272 m prior to leaving the principal deposit.
All Lumina sample assay results have been independently monitored through a quality control / quality assurance (QA/QC) programme, 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 in Peru for analysis. Gold content is determined by fire assay of a 30 g 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.
