Lumina Gold Announces Positive Cangrejos Metallurgical Testing Results

Lumina Gold (TSX-V:LUM) (the “Company” or “Lumina”) is pleased to announce that it has received positive results from the latest metallurgical testing program conducted on its 100% owned Cangrejos gold-copper project (the “Project”) located in southern Ecuador. The test results were the second round of metallurgical testing completed by the Company on the Project and demonstrated that the mineralized material can be processed by conventional industrial techniques.

Flotation combined with gravity concentration can be used to recover 83% of the gold and 87% of the copper into saleable concentrates. These results demonstrate a 4% improvement in the copper recoveries and similar gold recoveries when compared with the 2015 testing.
The results also demonstrate that cyanidation of the gravity concentrates and flotation cleaner scavenger tails is not required in the flow sheet, which was the most favourable recovery method during the 2015 testing. Alternatively, whole-ore cyanidation can be used to process the mineralized materials to recover 90% of the gold in dore, but no copper is recovered.
