Harvest Sites
Celtic Sea Minerals harvests in two key locations: the original site off the south west coast of Ireland – which has been worked since 1991 – and a significant and plentiful new reserve in Arnarfjordur, a fiord in the north west of Iceland.

The Icelandic source contains up to 35 million tonnes of Lithothamnion, compared with only one million tonnes off the coast of Ireland. Celtic Sea Minerals harvests large quantities of the Icelandic material a year through a joint venture agreement with a local company.
