David Henstridge,\nPresident, is pleased to announce the completion of a pulse electromagnetic\n(PEM) ground geophysical survey (the \"Survey\") over the Company's wholly-owned\nKalvbacken property located in the Bergslagen District, Sweden. Approximately\n18 line-kms of detailed geophysical recordings were collected.\nThe historic Kalvbacken sulphide deposits are located in a felsic\nmetavolcanic-\"quartzite\" complex near the contact with granite. The ore bodies\nare confined to two east-northeast striking horizons: one is an iron skarn\ntype occurring along a calcareous slate horizon; the other is a polymetallic\nmassive sulphide type occurring along a felsic metavolcanic-\"quartzite\"\nhorizon. The \"quartzite\" is an old term, sometimes referred to as an \"ore\nquartzite\". It is suggested by Company personnel and consultants that this\nunit is actually a metamorphosed rhyolite. An alteration zone, running more or\nless parallel with the granite contact, is bounded by granite in the north,\nand the alteration of the felsic metavolcanic has resulted in the development\nof the \"quartzitic\" rocks. The mineral associations occurring in the aureole\nseem to be the result of metamorphic differentiation, and sulphide minerals\nhave been formed later than the silicates.\nMapping by the Company's Swedish geologists has traced the favourable\nhorizon over about 2 km strike length along the \"quartzite\" - felsic\nmetavolcanic contact, grading into a granite - felsic metavolcanic contact.\nWithin the Kalvbacken property, and located on the felsic\nmetavolcanic-\"quartzite\" contact, an open pit reveals the location of the old\nsulphide deposits. Records show that the deposits consisted of two pipe-like\nore bodies that contained pyrite, sphalerite and galena and lesser\nchalcopyrite, pyrrhotite, antimony-sulphides, arsenopyrite and magnetite.\nTotal production between the 16th Century and 1963 is estimated at 662,000\ntons of zinc-lead-copper ore, but no grades are available. The descriptions of\nthe geology and mineral assemblages, plus observations made in the field by\nCompany personnel, indicate that this may actually be a volcanogenic massive\nsulp...
