Tellnes is the largest titanium deposit in Europe and probably the largest titanium deposit in production in the world today.

 It is one (of two) major hard-rock titanium deposits in production in the world. All other significant titanium mineral production are from sand deposits.

 The ore reserves are 380 million tons averaging 18 % TiO₂ of which approx. 15% TiO₂ is as ilmenite (30% ilmenite) and 3 % of the TiO₂ is within other minerals. At depth additional 250 million tons of ore has been identified.

 The Tellnes ilmenite reserve (57 mill. t. contained TiO₂) represents 14% of the world reserves of ilmenite, equivalent to 12 % of the total (ilmenite + rutile) world reserves of titanium minerals. The Tellnes yearly production, approx. 550.000 t ilmenite concentrate averaging 44.5 % TiO₂ in 1999, is 5% of the yearly production of titanium minerals (in contained TiO₂) in the world.
