Overview Kuervitikko is a Hannukainen-type iron-oxide-copper-gold (IOCG) deposit located 4 km north of Northland's Hannukainen deposit in northern Finland. This project could potentially add significant resources to the Hannukainen mine plan. Geology and Mineralization Kuervitikko consists of two, and possibly three, gently dipping magnetite-rich lenses, in similar host rocks to Hannukainen. These adjacent mineralized lenses hosted along a thrust structure trend from the southwest to the northeast and sub-cropping beneath overburden, which would be amenable to surface mining technique. Northland's drilling program covered an area of roughly 900m by 300m, and only tested part of 3 major aeromagnetic anomalies that outline the probable extent of mineralization. All but one of Northland's holes intersected the IOCG mineralization, underscoring management's belief that a substantial resource of IOCG mineralization may be identified as drilling progresses. Future Work The Kuervitikko is a high priority drill target for Northland. Future work will focus on additional geophysics, core drilling and the development of a NI 43-101 compliaint resource estimate. Drill Results Northland's drilling program outlined a potentially large zone of IOCG mineralization, approximately 25m thick on average, but ranging up to nearly 100m locally. Mineralization is horizontal or dips moderately to the west-southwest. The depth of mineralization ranges from 15-20m in the east where it sub-crops beneath the till, to 80-100m down dip in the west. A strike length of approximately 1,000m has been identified by drilling. An interpretation of an aerial magnetic survey indicates the potential of a strike length of approximately 2,300m.

Assay Protocol The core was cut at Northland's core facility in Kolari, Finland. A one-half split of the core from Kuervitikko was prepared at ALS Chemex Lab in Pieteå, Sweden and then transported to ALS Chemex Vancouver, British Columbia, Canada for analysis. Copper and Iron were analyzed by Sodium Peroxide Fusion multi-element analysis, with ICP-AES Method ME-ICP81. Gold was analyzed by Lead Fire Assay Pre-concentration with ICP-AES Method Au-ICP21 Finish. In addition to the ALS Chemex internal sample preparation and assay QC protocol, Northland maintains a rigorous QA/QC program consisting of inserting blanks, duplicates and certified standards to the analytical process. Historic Drilling Kuervitikko was first discovered by Rautaruukki during mining and exploration of the Rautuvaara mines and surrounding area. Rautaruukki completed airborne and ground geophysics, bedrock mapping and drilling between 1976 and 1987. Northland's field crew re-logged and, where possible, re-sampled archived core from the 40 or so holes that were drilled by either Rautaruukki or the Finnish Geological Survey (GTK) at Kuervitikko. Many of the holes have already been re-sampled and insufficient material was left for Northland to carry out a full re-assay program. In many instances, the only core left for re-assay was from the footwall or hanging wall of the mineralized lenses. |
