Geology

Iron mineralization in the form of magnetite hosted in an iron oxide apatite (Kiruna type) deposit. The ore has a size of 1500 x 600 m and a depth of 550 m. The primary ore is magnetite and actinolite with lesser apatite, iron, phosphorus, and other elements were remobilized and formed a secondary phosphate assemblage. Leveäniemigruvan is well known for its iron phosphate minerals. Very common are strengite, beraunite, rockbridgeite and a number of different zeolites.

Description

Leveäniemigruvan is a working, state owned, open cast iron-ore mine. The tours are offered by Dennis Holmberg. He is mineral collector and guides other mineral collectors to the most promising sites. Before the mine was reopened there was the possibility to enter certain parts, although the open cast was flooded. However, since it was reopened the site is fenced off and there are no official mine tours. Its only possible to visit the slag heaps and see the huge open cast from outside.

The mine was operated from 1964 to 1983, when it was closed due to sinking prices on the world market. The open cast subsequently filled with groundwater and formed a lake. In 2010, when the prices for many metals increased substantially, LKAB planned to reopen the old open pit and two others in the area. More than 30 million cubic meters of water were pumped since 2012 and mining resumed in 2016. At the current rate the reserves will last for about 12 to 15 years.
