Whitespots is of geological interest on account of its mineralogy, including a range of commercially mined metallic ores.

Minerals were deposited within a fault in the Silurian country rocks by hot, mineral-rich fluids. Minerals including galena, sphalerite, chalcopyrite, baryte, dolomite, calcite and chalcedony are present.

This site is the only occurrence in Northern Ireland of the unusual barium zeolite, harmotone.
