[{"type":"text","content":"\n\n\n\n\nTSXv - TM \nFrankfurt - TUY \nOTCBB - TUMIF\n\nVANCOUVER, Jan. 31 /CNW/ - Tumi Resources Limited (the \"Company\") \n(TSXv - TM; OTCBB - TUMIF; Frankfurt - TUY). Mr. David Henstridge, President,\nis pleased to announce the acquisition, through staking, of the Kalvbacken\n(168 hectares) and the Tomtebo (80 hectares) historic mining properties within\nthe Bergslagen district of south-central Sweden.\nThe Bergslagen district lies immediately to the north-west of Stockholm\nand covers an area of approximately 200 kms east-west by 150 kms north-south.\nThe district is underlain by volcanics and sediments which are more than\n2 billion years old. The region has undergone several phases of folding and\nhas been intruded by at least two generations of granitoids. Bergslagen is a\nhighly mineralized district and one of the most important ore districts in\nSweden, containing deposits of iron, manganese, base-metal and silver\nsulphides.\nThe historic Kalvbacken sulphide-ore deposit is situated 17 km southeast\nof Falun in central Sweden. The ores are located in a tuff-quartzite complex\nnear the contact with Archean granite. The ore-bodies, which are confined to\ntwo northeast striking skarn-carbonate horizons, are surrounded by an\nalteration aureole. The alteration zone, running more or less parallel with\nthe granite contact, is bounded by granite in the north. The alteration of the\ntuff has resulted in the development of different quartzitic rocks. The\nmineral associations occurring in the aureole seem to be the result of\nmetamorphic differentiation, and sulphide minerals have been formed later than\nthe silicates.\nThe deposit consists of two stock-like ore bodies, Kalvbicksmalmen and\nBligruvemalmen, which are parallel to the main regional tectonic fold axes.\nThese elongated skarn-carbonate bodies have been brecciated and partly, or\nentirely, replaced by sulphide ore. The surrounding quartzitic and tuffaceous\nrocks are relatively poor in sulphide-minerals. Pyrite, sphalerite and galena\nare the main ore minerals in skarn and carbonate rocks. Chalcopyrite,\npyrrhotite, antimony-sulphides, arsenopyrite, and magnetite are generally\nminor constituents. In quartzitic rocks, chalcopyrite and pyrrhotite are the\ndominating ore minerals. Silver in the ores usually amounted to less than\n200 g/t and gold less than 1 g/t.\nTh...
