VANCOUVER, July 19 /CNW/ - Tumi Resources Limited ("Tumi" and/or the
"Company") (TSXv-TM; OTCBB - TUMIF; Frankfurt - TUY). David Henstridge,
President, is pleased to announce the signing of an airborne electromagnetic
geophysical survey contract (the "Survey") to be performed by Skytem of
Denmark over the Company's ¿ster Silvberg, Tomtebo and Vitturn projects in the
Bergslagen District of Sweden. The Survey, which is scheduled to commence in
late August 2006, will total approximately 500 line-kilometres with line
spacings of 100 metres and covering an area of 50 km2.
¿ster Silvberg: The ¿ster Silvberg mine, located 27 km south of the city
of Falun, was once the chief producer of silver in Sweden in the fourteenth
and fifteenth centuries, but there has been no production since the
mid-1920's. The host rock is generally a metamorphosed, fine-grained, bedded
potassic rhyolite tuff. Near the ore contacts, the rock is often classified as
an "ore quartzite" which is actually the tuff that has been altered to mostly
quartz, garnet, mica, minor andalusite and other metamorphic minerals. The
mineral bodies at ¿ster Silvberg are found in cross-fractures, spatially
related to the metamorphosed tuff formations, which appear to have been formed
by the regional folding that deformed the host rocks.
The principal ore was an argentiferous galena that formed a columnar body
to the 220 metre level of the mine. Flanking the galena to the north and
southeast occur some narrower pyrite-sphalerite orebodies containing very
little galena and traces of chalcopyrite, quartz and fluorite. Complete mine
production and grade records are not available. Early records indicate that
silver production exceeded 32,000 ozs per year. One tabulation shows a total
of only 2,900 ozs of silver mined in thirteen different years between 1636 and
1920: the mine suffered several shut-downs in these centuries due to rock
caves. Various assays from the seventeenth and eighteenth centuries show that
the ¿ster Silvberg galena carried from 1,053 to 4,335 g/t silver. In addition,
the produced silver contained about 10% gold (from 100 to 430 g/t.)
The airborne survey will cover roughly 9 km strike length of favourable
geology that hosts the ¿ster Silvberg deposit. The area being flown is largely
covered by forest.
Tomtebo: The historic Tomtebo mine is located 25 km southeast of the city
of Falun, Sweden. Earliest records indicate that the Tomtebo mine was first
discovered and developed in the mid-seventeenth century, but detailed
production records were kept only in the early part of the twentieth century.
The mine has been closed since 1969. The host rocks are cordierite quartzite
and mica schists which grade into biotite-andalusite bearing quartzite. These
rocks are derived from highly potassic rhyolite tuffs.
Copper ore at the Tomtebo mine occurred in small folds as lenses or
stringers in an anticline. Between 1836 and 1837, 1,841 tons of copper and
1,077 tons of sulphur were produced. The copper content of the ore varied from
3.0% to 5.3% between the years 1915 and 1919. The average ore grade during the
last phase of mining, between 1965 and 1969, was about 1% copper, 1% zinc and
35% sulphur. An assay of fairly pure chalcopyrite (copper ore) gave 140 g/t
silver and 9 g/t gold.
The survey will test roughly a 3 km strike length of the mineralized
horizon. Tomtebo forms a small resistent knoll surrounded by flat farming
land.
Vitturn: A report on this area, discovered recently by the Company in the
Swedish Geological Survey library (G¿ran Fredrikson (1977)), revealed that a
ground magnetic and Slingram (electromagnetic) survey had been undertaken over
part of the Vitturn licence. The Slingram suvey defined a very strong anomaly
approximately 250m long and 50m wide and is reported as a steeply dipping good
electrical conductor. As impregnations of lead and zinc sulphide
mineralization within limestone were located about 200m to the NW of this
conductor, the Company believes this is a highly prospective target. No
drilling is known to have been undertaken within the area. It is believed the
airborne EM will define the exact location of this Slingram target and may
define further drill targets hidden beneath the Vitturn licence.
The property is underlain mostly by metamorphosed felsic volcanics with
lesser limestone and dolostone. The formations seem to bend from a dominantly
north-south trend at the southern part of the property to dominantly
northeast-southwest at the eastern end of the claim. The airborne survey will
cover about 9 km of projected strike length of the favourable horizon.
