Pool is said to have closed due to a dispute between the owners. Although it is also recorded that the lode was cut off by slide to the south. Development was by opencast methods and by three working shafts. The next recorded working was in 1853. It is also recorded that as well as the main N-S lead lode the sett also contained two other lodes. The owners had a large tracked of ground underlease, including The Loe (an expance of water cut off from the sea by a mud/gravel bar). They re-opened an adit driven through the cliffs at the southern end of The Loe to drain it (driven in the 1790 working to stop the water backing up and drowning the mine). By doing this the owners were able to remove up to 8mts of mud sediments, and work up to 1.25mts of alluvial cassiterite gravel/mud. The out flow frow this adit was used by tin streamers to work the tailings dumps of the mine.There was some prospecting at the mine about 1883, when test pits located the continuation of the lode south of the slide.
There are no recorded output figures for lead, silver or tin.
