Kåtåberget (Mo)

The Kåtaberget Mo project is located with Arvidsaur Mo – W – Sn province of NE Sweden (figures 1 & 2). Historically, molybdenum mineralisation was first discovered by a private prospector in 1970.

Follow-up geological studies were completed by Boliden Mineral AB and the Swedish Geological Survey within the area during the 1970’s however depressed global molybdenum prices at the time were considered too low to justify further exploration.

Historical exploration completed included: mapping, boulder tracing, geophysical surveying (ground magnetic, VLF, EM and IP), trenching and the excavation of a 800m2 area. Sampling of mineralised boulders/outcrop returned molybdenum grades up to 0.3% while results of geophysical surveying indicated that mineralisation is situated centrally within a large (5km) diaper structure (figures 3 & 4).

Principal geological units within the project area consist of intermediate to felsic volcanics which have been intruded by a series of sub-volcanic to later orogenic felsic intrusive (figure 5). Molybdenum mineralisation is interpreted to have probably formed within the roof zone of a late “Revsund type” orogenic granite and locally hosted by either coarse grained aplite or lesser pegmatite. Molybdenum occurs as irregularly distributed aggregates associated with fluorite and lesser amounts of pyrite and chalcopyrite.

Presently at the project an area of 200m2 x 85m2 has been defined with a grade of ~0.05% Mo however, mineralisation remains open to the south and south-west.
