David Henstridge,\nPresident of Tumi, announces developments on the Company's 100%-owned Tomtebo\nproperty located 25km southeast of the city of Falun, Bergslagen district,\ncentral Sweden. Following an airborne electromagnetic (EM) survey completed\nlast autumn, flown along lines spaced 100m apart, the data has been reviewed,\nmodelled and interpreted by an independent geophysicist in Australia. Numerous\nconductive zones were identified in the database; most were of "cultural"\norigin (powerlines, culverts, electric fences, buildings), but a few appear to\nbe legitimate targets near the old workings at Tomtebo.\n\n\nTomtebo is interpreted to be a classic VMS (volcanogenic massive\nsulphide) deposit hosted by highly deformed Precambrian felsic volcanics. The\nsulphide lenses have been rolled into steeply plunging cylindrical bodies of\nwhich four have been identified and mined on the property over about a 400m\ndistance northeast-southwest. Two smaller working exist about 150m southeast\nof the largest working mined at Tomtebo. Whether these occur along a separate\nhorizon from the Tomtebo lens(es) or occur along a folded continuation of the\nsame horizon is not known. However, there exists an unexplained EM conductor\nabout 300m northeast of these workings under a field with no visible evidence\nof a possible cultural conductive source.\n\n\nEarliest records indicate that the Tomtebo mine was first discovered and\ndeveloped in the mid-seventeenth century, but detailed production records were\nkept only in the early part of the twentieth century. It appears that the\nnorthernmost deposits were exploited for silver, lead and zinc, but the\nlargest working to the south was mined principally for copper in the twentieth\ncentury. Copper ore at Tomtebo was described as occurring in small folds as\nlenses or stringers in an anticline. The copper content of the ore varied from\n3.0% to 5.3% between the years 1915 and 1919. The average ore grade during the\nlast phase of mining, between 1965 and 1969, was about 1% Cu and 1% Zn. An\nassay of fairly pure chalcopyrite (copper ore) yielded 140 g/t Ag and\n9 g/t Au.\n\n\nThe Co...
