Boulby for Mines and Underground Laboratories

Boulby is a working potash and rock-salt mine with hundreds of miles of underground roads, tunnels and caverns. Alum was also mined near by to supply the die industry but potash and rock salt are now the main products taken from this deep mine facility. Polyhalite is another mineral they produce that consists of calcium, magnesium and potassium sulphates that can be crushed to produce a bulk fertiliser rich in sulphur.

You can see Boulby if you walk along the Cleveland Way between Runswick Bay and Staithes but the mine is quite discreet with only a chimney visible.
