This reporting covers weed control activities conducted at the <br /> Schwartzwalder Mine during the period of October 1, 2015 to September 30, 2016. The areas <br /> sprayed are marked on Figures 1 and 2. <br /> Weed control was completed in two applications (mainly spot spraying) during the 2015/2016 <br /> growing seasons in all areas adjacent to the entry road into the mine site. Weed control was <br /> applied on both sides of the road, around the mine pad area, settling ponds and between the <br /> north and south waste rock piles. Weed control was also completed on a certain percentage of <br /> both the north and south waste rock piles. Treatment continued along both sides of the road to <br /> the crossing of Ralston Creek and up to the upper cut-off wall including Phase 1 mitigation <br /> areas(see Figures 1 and 2). The targeted noxious weed species are listed in Table 1 along <br /> with their classification on the Colorado Department of Agriculture noxious weed list. <br /> Schwartzwalder Mine 2016 Weed Management Update Page 1 <br /> September 28,2016 <br />
