Founded in 2003, the company initially focused on exploring the potential for potash mining in North Dakota.

[4] However, after abandoning attempts at overseas exploration in February 2012[4] and following approval from the North York Moors National Park Authority in June 2015,[5] the then AIM-listed company stated that it would seek financing in order to begin construction at the Woodsmith Mine in North Yorkshire.

[7] In September 2019, the Woodsmith Mine project was in doubt when the company shelved a £400 million junk bond sale, citing a lack of government support and Brexit uncertainty.

[8] In November 2019, the company announced that it was in talks with potential investors to raise $600 million needed to fund the first phase of the development.
