Extensive laboratory testing work on an extraction process for the mining residues on the Montauban Mine Property demonstrated that a combination of gravity separation and closed circuit cyanization was the most effective process for the successful recovery of the precious metals. The combined extraction methodology increased the recovery percentages of gold and silver in the mining residues. With the implementation of the combined extraction methodology process, recovering up to 92% of the gold and 77% of the silver from the mining residues on the Montauban Mine Property
