Mawson stakes high grade iron oxide uranium mineralization at Asnebogruvan, Sweden
VANCOUVER, April 27 /CNW/ - Mawson Resources Limited ("Mawson") TSXv -
MAW. Mr Michael Hudson, President & CEO, is pleased to announce staking of the
Asnebogruvan Uranium Project in Sweden. Significant values from historic grab
samples from two mine pits included 4.7% uranium oxide, 28 g/t gold, 0.32%
tungsten, 2.7% tellurium, 0.15% yttrium, 10g/t silver and 25% iron oxide.
Two historic pits, located 60m apart, with diameters of 3.5 and 10 metres
respectively were sampled by the Swedish Geological Survey ("SGU") in 1980. A
grab sample from the 3.5 meter diameter pit assayed 4.7% uranium oxide, 28 g/t
gold, 0.32% wolfram, 2.7% tellurium, 0.15% yttrium, 10g/t silver and 25% iron
oxide and a grab sample from the 10m diameter pit assayed 12.6 g/t gold, 0.11%
wolfram, 1.0% tellurium, 10g/t silver and 30% iron oxide (uranium was not
analysed in this case). Pitchblende-bearing mineralization was noted to occur
within fractures and faults, and within a hematite brecciated sandstone.
Within the local area seven more uranium bearing fractures were noted.
The bedrock consists of sedimentary rocks belonging to the Dal-group,
which rest discordantly on an older crystalline basement made up of mainly
gneisses and granites. A granite body is mapped in outcrop some tens of meters
from the sampled pits. The area is considered to be prospective for iron oxide
hosted uranium-gold mineralization due to the presence of hematite breccia,
highly anomalous uranium, gold and rare earths in association with granites.
Three short drillholes were completed at Asnebogruvan by the SGU in 1980,
testing a 70m x 35m area. Metasediments of the Dal-group were intersected, and
thin iron oxide breccias within quartzites were encountered in two of the
holes. Only one hole was sampled and returned 3.3 metres for 30.2% iron oxide
and 0.08% tungsten. A map of the area can be found at
https://www.mawsonresources.com/index.php?page=ProjectsLangvat.
The area was also explored for stratabound uranium mineralization in 1970
by the SGU. One and a half kilometres east of sampled pits, still within
Mawson's claim area, drilling at the base of an albitised schist discovered an
irregular uranium horizon averaging 0.054% uranium oxide.
Mr Michael Hudson, President & CEO states, "The discovery of high-grade
uranium-gold-rare earth mineralization in hematite breccias at surface
demonstrates the potential for iron oxide, or Olympic Dam-type, uranium
mineralization at Asnebogruvan. Surface sampling, mapping and grid based gamma
radiation detector surveys are scheduled to target uranium mineralization
during the European spring."
The Asnebogruvan prospect is contained within the 774 Ha Langvattnet nr 2
application, in the Bengtsfors Kommun, Province of Vastra Gotalands in central
western Sweden. The application has been confirmed by the Swedish Mining
Inspectorate and is expected to be soon granted for an initial period of three
years.
Ten nuclear power reactors provide approximately 50% of Sweden's
electricity. Swedish mining legislation allows exploration for uranium and
places no special restriction on mining where the uranium grade is less than
200 ppm or the production is less than 5 kg. When higher uranium grades are
present, permitting will follow a process concerning "nuclear technical
activity". Such permitting must pass before the Swedish government for
decision making.
Mark Saxon, Vice-President of Exploration and Director of Mawson and a
Member of the AusIMM, is the qualified person as defined by National
Instrument 43-101, has verified the information contained in this release.
On behalf of the Board,
"Michael Hudson"
