(10/12/1994) Centred SX 63386694. Several lines of shallow tin pits running roughly east to west on the crest of the ridge separating Dry Lake from Wollake. The pits are small, in the region of 3.0m in diameter, and around 0.5m deep. They appear to be associated with a lode pursued by an openwork running east from Wollake (SX 66 NW 113) and a streamwork (part of SX 66 NW 72) branching west from Dry Lake.

Two hectares of tin streamworks and prospecting pits branching off the eastern side of Blacklane Brook. The deposits worked here represent an extension of those worked on the west side of the brook (MDV25039). The interior working area contains the usual evidence of low linear spoil heaps, pits and channels, but as the working extends to the east the streamworking, makes way for a linear cluster of prospecting or trial pits. The approximately circular trial pits are up to 5 metres diameter and 1 to 2 metres deep, though some larger examples may be shallow shafts. Each pit has a small collar of spoil on the downslope side. The pits and streamworks have not been dated but are likely to be post-medieval.
