David Henstridge,\nPresident, is pleased to announce the start of a pulse electromagnetic (PEM)\nground geophysical survey (the \"Survey\") over the Company's wholly-owned\nKalvbacken property located in the Bergslagen District, 17 km southeast of\nFalun, central Sweden. The Survey will cover an area of about 460 hectares\n(4.6 square km), involving about 40 line-kms.\nThe historic Kalvbacken sulphide deposits are located in a felsic\nmetavolcanic-quartzite complex near the contact with granite. The ore-bodies,\nwhich are confined to two northeast striking skarn-carbonate horizons, are\nsurrounded by an alteration aureole. The alteration zone, running more or less\nparallel with the granite contact, is bounded by granite in the north, and the\nalteration of the felsic metavolcanic has resulted in the development of\n\"quartzitic\" rocks. The mineral associations occurring in the aureole seem to\nbe the result of metamorphic differentiation, and sulphide minerals have been\nformed later than the silicates.\nMapping by the Company's Swedish geologists has traced the favourable\nhorizon over about 2km 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-quartz contact, an open pit reveals the location of the old\nsulphide deposits. Records show that the deposits consisted of two stock-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\nsulphide deposit (Kuroko-type) which has been deformed, metasomatised (skarn\nminerals) and the sulphides re-deposited into the skarn and carbonate rocks.\nThe PEM survey will target the felsic metavolcanic-quartzite contact\nwithin the claim block and any possible hidden extens...
