Drilling Program Completed At the Cangrejos Deposit

 

VANCOUVER, BC - Lumina Gold Corp. reported drill results from the thirteen hole metallurgical and pit slope geotechnical drilling program completed in 2019. These holes represent approximately 4,910 meters of drilling. All of the holes were on the Cangrejos deposit and were drilled to support ongoing engineering and economic study work. Geotechnical holes were sited throughout the resource area to characterize structural, rock mechanics and hydrogeologic conditions within the June 2018 Preliminary Economic Assessments’ (PEA) ultimate pit and to support future pit slope design engineering. Holes were typically collared within the known resource and angled across pit boundaries defined by the PEA mine plan. The holes did not specifically target mineralization, yet many cut significant intervals. Hole G2B cut one of the best mineralized intervals ever drilled at Cangrejos with 444 meters averaging 1.18 g/t gold and 0.09% copper from 4 meters below surface. In addition to high grades, G2B exhibited remarkable continuity of mineralization throughout the hole.

The metallurgical holes were drilled with large-diameter core (PQ) for multiple purposes. The holes targeted various rock types so composites could be prepared for 1) comminution testing, specifically High-Pressure Grinding Roll (HPGR) tests completed by FLSmidth Labs in Utah, USA and 2) corresponding metallurgical flowsheet development by Plenge Metallurgical Labs in Lima, Peru. Lumina expects results from the ongoing 2019 metallurgical test program to be released this month.

Drilling at the Gran Bestia ridgeline is continuing with the expectation that drilling will conclude in September and a new resource estimate for Cangrejos, including Gran Bestia will be released in November. The new resource estimate will support Lumina’s assessment of future exploration and drilling needs. Gran Bestia drill holes 140 to 147 are pending results or in progress (see below drill hole location map). Hole 147 will be the last hole prior to the program ending.
