Technical Information

The deposit is situated in the contact zone between the Himanka volcanites and metapelitic schists. Ductile-brittle shears are focused within sub-vertical, northwest-striking en-echelon mineralised lenses and the orientation of the lenses follows the strike of the shears. The gold mineralisation is associated with quartz and sulphides emplaced parallel with the strike and dip of the shearing and lithological units. The main host rock of the gold mineralisation is a meta-felsic volcanic sequence.

Exploration has so far identified mineralisation with a north westerly strike, 1.5 kilometres in length and with a subvertical dip. Drilling is down to a 50-metre grid in places, but further infill drilling is required where holes are spaced 100-200 metres apart.

A parallel zone, on a similar geophysical anomaly has been intersected in two holes 1200m apart, this and several boulder trains with unidentified sources open up the potential of the area significantly.

The NI 43-101 Technical Report “Hirsikangas Gold Deposit, Central Ostrobothnia, Finland” was filed on SEDAR on 30th November, 2009. The Technical Report and mineral resource estimate has been prepared under the supervision of Thomas Lindholm (MSc, FAusIMM) of GeoVista AB of Sweden, acting as an independent “Qualified Person” according to NI 43-101. The mineral resource estimate has an effective date of 30th November, 2009, and the results were first disclosed in a press release dated 1st December, 2009.

The ore resource was calculated using block modeling made up of 10m x 10m x 2m blocks with sub-blocks down to 2.5m x 2.5m x 0.5m. The block models were constrained by a wireframed three-dimensional volume interpreted from mineralised structures on oblique sections. The grades inside the blocks were calculated using the Inverse Distance Squared Method, with several passes. The Indicated Resources are where drilling was on a grid of 50m x 50m. The Inferred Resources are where drill spacing was greater than 50m x 100m. An average specific gravity of 2.72 g/cm3 was assigned for all blocks.
