Drifts were cut near Post Gate Hill around 1870, traces of these remain although now appear to be used as a modern water source.
The only sizeable remains on the site are those of a bridge under which an incline from the mine site seems to have run. The tramway from this location entered a tunnel around NZ 774054 then travelled below Glaisdale village and emerged onto a trestle bridge near the ironworks around NZ 777055.
Whilst walking in the area yesterday I saw various orange streams, indicating the presence of iron over a remarkably wide area.
