Property History
Sahavaara was drilled by the Swedish Geological Survey (SGU) in 1967. The SGU completed a rough resource estimate (non NI 43-101 compliant) on the basis of their drilling which tested down to 750 meters. The SGU established that a significant magnetite body was present containing additional by-product copper credits. Little further work was done, however, until Northland acquired the project in 2004.
Northland has systematically drill-tested the magnetite body using large diameter core where possible. Our geologists have also re-logged and re-sampled the historic core stored in the SGU core archive. The large diameter core also provided sufficient material for initial metallurgical test work and completion of a NI 43-101 compliant resource calculation in May, 2006.
During the spring of 2007, Northland hired a local excavation contractor to clear the overlying glacial till and prepare the access ramp for the start of the underground phase of a bulk sample.
After completion of an access ramp to the magnetite, the contractor blasted a 50 meter long horizontal tunnel within the magnetite from which a 2,000 tonne bulk sample of material was collected. A representative sample of this material was then sent to the metallurgical testing laboratory (SGS Group) in Ontario, Canada.
During the 3rd quarter 2008, the Company completed bulk sampling at Sahavaara, by drilling 30 holes, totaling 3,726 metres.
Additional metallurgical drill core was taken during 2008 to provide a representation of all the ore types in the resource and more definitive metallurgical testing took place at GTK in Finland during 2009.
