Lumina Gold Corp announced drill results from the last eight holes of the 2018 and 2019 drill program and the expansion of the Gran Bestia mineralized zone to the northwest. These holes represent approximately 3,900 metres of drilling. All of the holes except for one were on the Gran Bestia Deposit. These holes will be the last results included in an updated NI 43-101 resource estimate expected in November. Marshall Koval, President and CEO, said that we are extremely excited by the continuity of mineralization found during the Gran Bestia ridgeline drilling. These results will add a substantial amount of mineralized material to the project when we complete the maiden Gran Bestia resource estimate. Gran Bestia will complement the already large-scale Cangrejos deposit and should provide mine life extension and mine plan flexibility when we look to update the project’s economic study in 2020. The deposit remains open to the northwest, north, northeast and at depth.

Cangrejos Deposit: Hole 140 was drilled on the northwest side of the main resource in an area that has demonstrated high-grade results from surface across multiple holes from the same pad. The best result from the pad was hole 138, drilled to the south, which returned 302 metres grading 1.22 g/t gold and 0.14% copper. Hole 140 was drilled westward and contained a surface intersection of 0.74 g/t gold and 0.08% copper to 116-metre depth, including 1.16 g/t from collar to 14 metres.

Gran Bestia: Hole 141 was a vertical hole drilled from the same pad as the longest intersection at Gran Bestia to date, hole 105, which returned 626 metres of 0.62 g/t gold and 0.11% copper. Hole 141 contained an intercept from surface of 138 metres grading 0.57 g/t gold and 0.09% copper, including 18 metres averaging 2.41 g/t gold and 0.25% copper from 30- to 48-metre depth.

Gran Bestia Ridgeline: Holes 142 to 147 were drilled to explore the large untested ridgeline breccia area above the significant mineralization discovered with prior Gran Bestia drilling. Intrusive and hydrothermal breccias are the dominant geology of the ridgeline. Alteration and mineralization intensifies with depth, particularly below 100-metres vertically. Hole 144 was a hole angled to the southeast from the highest pad and drilled to test continuity of mineralization north-northeast of hole 105. This hole intersected 577 metres of mineralization in a 675 metre deep hole. The final 375 metres of the hole averaged 0.60 g/t gold and 0.08% copper including an 88-metre zone averaging 1.25 g/t gold and 0.12% copper. The final holes drilled, 145 to 147 (145 was lost at 234 metres) were drilled vertically from the ridge crest pads. Holes 146 and 147 after cutting lower-grade mineralization near surface, hit the higher-grade zone at depth leaving Gran Bestia completely open to the northeast, north, northwest and at depth.
