(1) In 1955, a 750-foot crosscut was driven in a northwest direction on the 38th level to intersect an ore shoot outlined by underground diamond drilling.(2) Current mining follows a careful plan in which crosscuts are run at discrete intervals off of the main level 5 access drift toward areas of potentially productive ground.(3) The mine was worked by tributers, who recovered a small amount of copper from the crosscuts .(4) At the bottom of the shaft two 700-foot crosscuts were driven in a northwest and southeast direction.(5) Additional crosscuts were driven from the 12th and 30th levels of the mine to determine the characteristics of the ore at greater depths.
