Wheal Lushington Mine, also known as West Wheal Towan Mine comprises and amalgamation of a number of small and ancient mining setts that occupy a strip of coastline extending over a distance of around 1500 metres from the western side of Porthtowan Beach to the eastern side of Keriack Cove. Whilst the western section of the sett lies within the parish of Portreath, the mine is included within the Porthtowan mining district. Portreath village itself lies over 2.5 km to the south-west of the western boundary of the sett and if used, gives a misleading geographic location for the site.

The small mines that comprise the sett are as follows:

Wheal Sally - located on the east side of Keriack Cove extending south into the valley that leads into Keriack Cove. Between 1920 and 1925 this mine was investigated under the name Sally Bottoms and a new shaft sunk. Some reasonable values were encountered, but these proved to be patchy. No production ensued.
