Executive Summary
This NI 43-101 Technical Report describes the recovery methods for the Vetas Gold Project operated by Galway Gold Inc. The process flowsheet employs a combination of gravity separation techniques and cyanide leaching to recover gold from the ore. The flowsheet includes primary crushing followed by grinding, with an initial gravity concentration stage using jigs to recover coarse free gold. The jig concentrate undergoes panning for final gold recovery, while the middlings are sent to regrind before processing through shaking tables. The finer fraction from the grinding circuit is processed through heap leach with cyanide solution, with the pregnant leach solution treated via Merrill Crowe zinc precipitation before refining to produce gold doré bars. Additionally, an agitated cyanide leach processes the gravity tailings, with the resulting solution also directed to zinc precipitation. Reported production averages approximately 500 ounces of gold per year over the past five years of operation.
Processing Overview
The Vetas Gold Project utilizes a combined gravity and cyanide leaching flowsheet. Initial crushing and grinding is followed by gravity concentration using jigs, with the coarse concentrate panned for free gold recovery. The jig middlings undergo regrinding before processing through Wilfley shaking tables. Finer material from the grinding circuit proceeds to heap leach with cyanide percolation. Both the heap leach pregnant solution and the agitated leach solution are processed through Merrill Crowe zinc precipitation before final refining to produce gold doré bars. cyanide destruction using hydrogen peroxide is employed for tailings treatment prior to disposal.
