General 2015-05-10The Malmberget mine consists of about 20 orebodies, of which ten are currently mined. Most of the deposit consists of magnetite ore, but non-magnetic hematite also occurs. The present main level of the Malmberget mine is at a depth of 1000 meters. Mining in Malmberget takes place at several different levels, since there are many orebodies. The main haulage levels are at 600, 815 and 1000 meters. There are crushers at each level. 12 huge mine trucks, with payload capacities of 70 to 120 tonnes, are operated at these levels. The trucks are driven to vertical shafts. Drivers control loading from inside the cab of the truck. The fully-loaded truck is then driven to a discharge station and the ore is emptied into a crusher bin. The trucks are emptied sideways. This is also controlled from the cab of the truck. The ore is fed into the crusher and crushed into lumps of about 100 mm in diameter. From main level 1000, the crushed ore is hauled by a 1.7-km-long conveyor to a skip shaft at the 815-meter level. From there, the ore is lifted to the surface by two skips. Final transport to the processing plants is via belt conveyor. There is also a crusher and hoisting station at level 600, for ore mined in the Western field, where there is also hematite ore.

Avalon switches to copper-only focus at Viscaria 2015-12-14A scoping study into the Viscaria copper project, in Sweden, has confirmed that a copper-only development could be justified. In 2013, project owner Avalon Minerals conducted a scoping study on the copper and iron potential at the Viscaria project, which revealed that an openpit mining operation could produce between 15 000 t/y and 22 000 t/y of copper, based on a production rate of 3.5-million tonnes a year and a mine-life of some 10.3 years.
