I sent an e-mail to Prof. Burt, one of the co-authors of the book pointing out that one of the NGR puts the mine somewhere in the south-west approaches. I wasn’t being presumptuous because the authors had asked to be informed of any errors. This was his reply:

Dear Malcolm,
Yes - we have noticed this. The problem was a transposition of number i think, which is almost inevitable in a volume like that - it was not possible to properly proof read it and that kind of issue creeps in. BUT we are now producing a new and much enlarged edition of that volume - which will appear on CD ROM to make use easier - and I hope that we might be able to correct some errors then - but I'll say now, there's bound to be some others!

New edition sounds very interesting. In case anyone is unaware the other publications in the series are:

The Derbyshire Mineral Statistics 1845-1913
The Yorkshire M.S 1845-1913
The Cumberland M.S. 18451913
The Lancashire and Westmorland with the Isle of Man M.S. 1845 -1913
The Durham and Northumberland M.S. 1845-1913
Devon and Somerset Mines 1845-1913
The Mines of Cardiganshire 1845-1913

As ref. books I would say they are unbeatable.

The Devon & Somerset book is also littered with errors. My opinion on these books are that they were done in a hurry without any checking of the facts and figures. Basically, just churned out. I have in my data-base figures that have not been included in the above listed book that were very easy to obtain. I don't hold much hope out for the next version which has been in the pipeline for a while now. I wont be purchasing it.
