Galleon Gold Announces Strong Recoveries in Metallurgical Studies for West Cache
"We are very pleased with the recovery rates which indicate Zone #9 gold mineralization can be efficiently recovered using one of three commonly-used industry-standard processing methods," R. David Russell, CEO and President of Galleon Gold, said.
Galleon Gold Corp. has announced very favourable results from ongoing metallurgical test work performed on three composited core-based bulk samples from Zone #9 at its 100% owned West Cache Gold Project, Timmins.
"Further metallurgical test work on West Cache bulk samples will help the Company select the most suitable process for toll processing. The recent Study was undertaken in support of the PEA that is currently underway with all three processing methods producing such favourable results, we now have more toll processing options available to us."
Three primary processing options for gold recovery have been studied at the SGS Lakefield, Ontario facility: 1) Gravity - Flotation, 2) Whole Ore, and 3) Gravity - Whole Ore. Results from all three processing paths indicate strong gold extractions can be achieved on each of the low (1.77 g/t), mid (5.10 g/t) and high (21.9 g/t) grade portions of the recently identified Zone #9 gold mineralization. Highlights from this work, include:
- Whole Ore Leach: Gold Extraction1 ranging from 83% to 97% - depending on grind size and composite feed grade
- Gravity - Whole Ore Leach: Gold Extraction1 of 95% to 97%
- Gravity - Flotation - Concentrate Leach: Gold Extraction1 of up to 97%
Extraction1- all references to gold recoveries here are based on gold "extraction" studies. Minor inefficiencies in the overall recovery process from leach solutions will result in small gold losses - this separates gold extraction from gold recovery. These losses can be estimated once all test work has been completed.
Whole Ore Leach Results
Whole ore leach, the simplest processing option, follows the crushing, grinding, leaching and recovery of the dissolved gold flowsheet. The following test results show that over 90% of the gold can be extracted in simple tank leach of the whole ore, while remaining insensitive to the gold grades being evaluated.
