Switch Metals plc (formerly Oneiro Energy plc)

Visit Client Site Switch Metals

Switch Metals plc (formerly Oneiro Energy plc) (SWT.L) is the largest holder of coltan (tantalum and niobium) and lithium licences in Côte d’Ivoire with more than 3,000 km2, including licence applications. It has secured 100% control of its three key projects, ISSIA, TIASSALE, and BOUAKE. All projects have favourable road access and infrastructure in place, and cover historically documented occurrences of coltan (tantalum, niobium) or lithium.

Switch’s priority is to hedge exploration risk through early cashflow generation. To realise this ambition, it is quickly advancing its flagship Issia tantalum project towards resource definition, development and production. This cashflow foundation will support future growth through exploration upside or new asset acquisitions.
