Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.

In late 2016, spodumene was reported as present in the tantalite ore at the pegmatite deposit with the commencement of metallurgical test work, exploration and resource drilling 19. A maiden lithium mineral resource was released in 2017 20 and a further resource estimate was published in 2018 21 .

Tantalum occurs most frequently naturally in the form of tantalite ore which has the formula (Fe,Mn) [(Nb,Ta)O 3] 2. When the tantalum content predominates, the ore is referred to as tantalite. When more niobium than tantalum is present, it is known as columbite or niobite.
