Clough & Associates Ltd. Page 22 Union Hill Heritage Management Plan WGCL Kilns 10 ore roasting kilns in two rows, with associated access tunnels; c. 6.7m to 8m in diameter, c.8m to 8.8m in depth; 4 of the kilns are brick lined. A probable remnant of the 1886 Union Level drive consisting of a 2m section of tunnel is apparent in the wall between kilns 3 and 9. A buried tramway section is present at the southern end, subsurface but visible in a collapsed hole. (See Appendix A, Figure D) Vegetation on kiln walls and some large pines – notably in kiln 7, where tree roots now an integral part of the kiln wall. Stable apart from rock falls within access tunnels and around one of the tunnel portals. Tunnel portal entrances cordoned off with safety signs. Kilns not clearly visible from access point at N end. Stability is being monitored during Trio mine operations (2004 photo) WGCL Cyanide tanks 6 ferro-concrete cylindrical air agitation cyanide tanks supported on bases with 6 radiating legs 2-2.6m long; c.16.5m high and 3.7m in diameter. (See Appendix, Figure E) Good/stable condition, but concrete has been broken away from parts of bases; legs of one tank damaged by explosives. Stability is being monitored during Trio mine operations. Clear of vegetation externally but not internally. Tall pines located nearby with potential to fall and damage the tanks. Visible and easily accessible. (2004 photo)
