Chromite was first found in Unst by Dr. Hibbert in 1817.  In the 1820’s mining was begun and proved successful.  A large deposit was found at Hagdale and equipment was installed there for pumping out water and also for crushing.

Soapstone (talc) was quarried at Quoys for many years and when that seam ran out a quarry was opened at Clibberswick.  ‘Kleber’ is the old Norse word for soapstone.

Traces of many other minerals have been found in Unst, but not in sufficient quantities to warrant mining.  Unst, with its diverse geology, has been called the ‘Geologist’s paradise’.
