The database behind this mapping began life as a paper index of sites in the Northern Cavern & Mine Research Society Records in the early 1960s. It was digitised, in dBASE III format, in the late 1980s and is now held in Access and contains a wide range of information. The Northern Mine Research Society is pleased to make this valuable tool freely available to anyone interested in mining history.

Please note that sites are recorded as point data, but it must be remembered that some occupied larger areas.

We also have other maps covering mining and these can be found here


No project like this can be completed without help from a wide range of individuals, and over fifty years many people have contributed data, much of it from NMRS publications. This part of the database is, by far, the least well developed and represents an area ignored by many mining historians.

Especial thanks are due to: Theodore Faull, Head of GIS at Terrafirma Mine Searches Ltd., for converting files for use with Google Maps.

This sections includes evaporate minerals which formed where seas and lakes have evaporated, causing higher salinity, more quickly than they are replenished. They include Rock Salt, Gypsum and Potash.
