This web site provides an on-line searchable version of the late Jeremy Wilkinson’s Gazetteer and Bibliography of the Mines and Quarries of North Wales. The gazetteer currently contains entries for more than 4,700 documented mine, quarry and other site names plus entries for around 2,000 other sites (unnamed levels, pits, quarries, shafts etc.) identified from historic maps. Alternative names of sites are cross-referenced. Supporting this data is a bibliography of more than 35,000 references and notes. Details are provided of more than 1200 limited companies and more than 3,600 other companies and individuals are named.
The Gazetteer and Bibliography was originally compiled over a considerable number of years by Jeremy Wilkinson from Public Record Office and other sources of public record. He used the data and a set of BASIC programs to create a database, initially on a BBC B computer and later on PCs.
Following a conversation in June 2002, Jeremy asked me, Dave Linton, to produce an online version and subsequently provided me with copies of his files. I have modified file names, formats and some data codings to simplify maintenance and reduce file sizes. Duplicated data have been eliminated and minor corrections have been made. The files and their data formats have been documented to support future maintenance.
I have used my versions of Jeremy’s files and my own programs to produce the gazetteer and bibliography of mines and quarries in north Wales and the persons associated with the mines and quarries, plus a list of relevant Crown Grants. Cross-references that provide additional information to that currently display are presented as links.
In addition, references to further secondary sources have been added as in many cases these are more accessible than the primary sources.
Additions and corrections to the data have been, and will continue to be, incorporated as further information becomes available. Submissions of such information will be welcomed.
Detailed information about the changes to Jeremy's data can be found on the Gazetteer Data page.
The Gazetteer and Bibliography consists of an entry for each mine and quarry in the pre-1974 counties of Angelsey, Caernarfonshire, Denbighshire, Flintshire and Merioneth of north Wales. Each entry has, where available, the following information:
Searches can be made by site name, location (specified as place name, grid reference, latitude/longitude or postcode), product, county, parish, or any combination of these.
The results can be displayed as a list of site names and summary information, full gazetteer details or as locations (where known) on a map.

Jeremy recorded more than 1,300 sites that appeared on maps but were otherwise unreferenced by giving them the name of a nearby map feature. Thus, an isolated level, marked as Old Level on the map, with no documented history, was recorded with a name such as “CERIG HEUNON MINE”. Where appropriate, such names have been changed to the type of feature recorded on the map – in the case of the example given, the site would be shown as “LEVEL”.
There is also a list of Crown Grants with, again where available, the following information:
See example entry or search the Crown Grants
Finally, there is an alphabetical list of persons, companies and organisations who were associated with the mines and quarries or who were Crown Grantees. It contains the following information:

Jeremy Wilkinson’s work in researching and collecting this data was considerable, and the mining history community owes him a signifcant debt. This is evident by the number of times his contribution is acknowledged in various mining, quarrying and railway history books. In addition, the suggestion that the information be made public on the World Wide Web came from him. As well as his data files mentioned above, Jeremy also passed on to me his index cards, various notes and correspondence, photocopies of HM Mines Inspectors’ reports and his collection of OS six-inch county maps on microfilm.
Christopher Fleet of the National Library of Scotland has provided assistance in enabling me to provide on-line access to the OS six-inch map sheets referenced by the data. The on-line map images hosted by NLS are a major resource and add considerably to the utility of this gazetteer and bibliography.
