orogenic Gold deposit 15 km NE of Kittilä.

Hirvilavanmaa is situated in the southern part of the CLB, approximately 15 km northeast from the town of Kittilä; it is the closest discovered deposit to the intersection between the SiSZ and the KiSZ (approximately 0.5 km). A resource estimate of 0.11 Mt of ore grading at 2.9 ppm Au has been calculated for Hirvilavanmaa. The currently known NNE-trending mineralized domain is 270 m long and 90 m wide with narrow lens-like mineralized bodies dipping at 85 degrees (dip azimuth = 270°). Recent drilling has indicated that the mineralized zone extends both vertically and horizontally beyond previously set limits, remaining open at depth and along strike to the north. Hirvilavanmaa is hosted mainly by magnetite-rich ultramafic metavolcanic rocks of komatiitic affinity that strike NW in the area near the deposit; the ultramafic rocks belong to the Sattasvaara formation of the Savukoski group. The komatiitic rocks have been intensely altered and deformed and appear as various schists, albite-carbonate-chlorite-sericite rocks and carbonate rocks; the latter include a fuchsite-bearing variety that have been termed “chromian marbles” and were marketed commercially as a natural stone material.
