This reporting covers weed control activities conducted at the Schwartzwalder Mine <br />between September 28, 2012 and September 28, 2013. <br />Weed control was completed in four applications (including spot and broadcast spraying <br />methods) during the growing season 2012/2013 in all areas adjacent to the entry road into the <br />mine site. Weed control was applied on both sides of the road, around the mine pad area, <br />settling ponds and between the north and south waste rock piles. Treatment continued along <br />both sides of the road to the crossing of Ralston Creek and up to the upper cut -off wall including <br />Phase I mitigation areas (see Figure 1). The targeted noxious weed species are listed in Table <br />1 along with their classification on the Colorado Department of Agriculture noxious weed list. <br />Schwartzwalder Mine Weed Management Update Page 1 <br />September 28, 2013 <br />
