Hi Rooman and welcome to the site.
There is a new book out which covers some of the mining round the Holme Valley. Check with Holmfirth or New Mill library. One of the authors is on this site so might get in touch. He specialises on the Tinkers and Hepworth Iron Mines.
I think you should get in touch with me so we can help each other out in this area.
[email protected]The West face of the Holme Valley is riddled with old mine from Kings Bridge, Newsome, Berry Brow, Honley, Brockholes, Thurstonland, New Mill, Jackson Bridge right up to Hazlehead.
I would be interested to know of the open addit you talk about.
Roy I would like to throw some light onto the Holmfirth Area which is an Area of Kirklees. There is more mining round this area than Barnsley and Wakefield put together. we have most outcrops. 'Compo' would turn over in his grave.
