Sylvanite Gold Tailings
The Sylvanite Gold Tailings project is located 3km from the Teck-Hughes project in Ontario, Canada.
The project is the mine waste at a former producing mine located 3km from the Teck-Hughes project. The fifth largest producing mine in the Kirkland Lake gold camp, the mine milled 4.58 million tonnes of ore and produced 1.67 million ounces of gold between 1927 and 1961. A 1986 report, filed on the property, estimated a tailings resource of 4.14 million tonnes grading 0.47g/t Au containing 67,051 ounces of gold*.
Initial Batch leach testing using Extrakt non-cyanide Leach Technology produced significant results with gold recovery of 49% over leach times as little as 3 hours. This demonstrates an exceptional increase in gold recovery (>60%) and reduction of leach times (<90%) compared to previous best cyanide based leaching recoveries of 30% over 48 hours.
