Current reserves (year end 2013) stand at 4.7 million contained ounces and exploration efforts continue to search for additional resources. The bulk of the gold mineralization has been produced from narrow, high-grade veins hosted in an Oligocene, alkaline, diatreme-intrusive complex. Gold has also been produced from mineralization hosted by the Precambrian rocks where the vein systems were strong enough to penetrate from the diatreme. More recently, gold has been produced by bulk mining methods in the low-grade haloes around the vein systems. A road log and two reprinted articles are included.;
