The proposed WUG Portal would appear to intersect and will impact on a subsurface mining shaft associated with the Silverton Mining complex on the southern slope of Silverton Hill (see Figure 38). T13/820 Winner Hill Gold Mining The Winner Hill gold mining complex is an area of goldmining remains over Winner Hill, including drives, shafts, terraces and tailings. The proposed Gladstone open pit will partially remove the 12m Winner Winze at 1110RL in the south west of the pit shell and several other pre-1900 historic level drives to the south and east of the proposed pit (Figure 38). These relate to surface Feature b) recorded by Phillips (2000), an area of spoil near the summit of the hill, and another pre-1900 historic drive with an exposed entrance and mining debris in the streambed below recorded as surface Feature e), located in the southeast of the proposed pit. The Winner Hill gold mining site has already been affected by modern gold prospecting from the 1970s until 1999 and the planting of a pine plantation across Winner Hill. The possibility of additional subsurface remains in relation to past mining activities cannot be
