The witherite, calcite, fluorite, barite, linarite, barytocalcite and plumbogummite have never been beaten, mimetite from Dry Gill (the variety known as campylite) is unique, and the recent finds of boracite from Boulby mine have set new standards for the species.

The mine is the type locality for barytocalcite (Brooke, 1824), and has yielded some good specimens (lustrous, transparent, prismatic crystals to nearly 1 cm); in fact, it is the only locality in the world where that mineral has been commercially mined.
The mineral, at first thought to be a form of barytocalcite, is trimorphous with bary-tocalcite and paralstonite, and forms white to colorless or faintly pink acute pseudohexagonal pyramids or dipyramids up to 6 mm long.

Natrolite in the cavities is overgrown by calcite, fluorite, barytocalcite, podlesnoite, astrophyllite and, in minor amounts, burbankite, lemmleinite-K and fluorapophyllite.
Metamorphism of the sediments transformed the witherite into sanbornite (with barytocalcite as a possible intermediate product) but the barite remained unchanged because of its high melting temperature.
