Thanks for spotting that John. I have binned the clearwell page and added it to the Old ham page. The mine was worked very recently so it may have been worked under the guise of Clearwell. The second entry is for old ham pit, which shows some 500 ish metres away.
this is always going to be a problem when people add things to the data base, places can be called something slightly different, or a name altered over the years and it can create a right confusing issue.
