Castle Silver Resources Plans Metallurgical Evaluation of Cobalt and Silver Recovery

Castle Silver Resources today announced a new program of metallurgical testing aimed at evaluating the potential recovery of cobalt and silver from tailings and waste pile samples collected at the Castle Silver and Beaver Silver historic mine properties south of Kirkland Lake, Ontario.
As quoted in the press release:

Frank Basa, President and CEO, stated, “The assay tests we have so far are indicating that previous mining at Castle and Beaver left behind significant amounts of silver and cobalt in both tailings and waste piles. We believe it appropriate at this point to take it a step further by initiating metallurgical testing to determine the best method of extracting the remaining metals, particularly silver and cobalt, which is experiencing increasing market demand due to its use in phone and electric car batteries.”
