VANCOUVER, May 21, 2013 /CNW/ - Mawson Resources Limited ("Mawson") TSX - MAW; Frankfurt - MXR, PINKSHEETS- MWSNF provides a compilation and assessment of results from the 2013 winter
program for the Rompas high-grade, greenfield gold project located in
Rompas' district scale potential was confirmed via further surface discoveries of multiple high-grade gold anomalies, such as Rajapalot, which has expanded the project to greater than 100 km². Fifty eight new gold anomalous target areas have been identified for
follow up during the 2013 summer field season.
A team of ten Finnish geologists is being mobilized to the Rompas project area to undertake an intensive
field season to commence in early June 2013.
A LIDAR airborne survey completed in 2012 gives Mawson's field
geologists more accurate data that will allow much more rapid data
collection. This new technology allows outcrops that previously took
weeks to be located, to be identified and mapped in only days.
Non-selective, heavy mineral soil sampling from South Rompas discovered one of the best heavy mineral samples collected within the Fennoscandian
Shield, with 5,000 gold nuggets recovered from a 5 litre sample. Further heavy mineral sampling is
planned on a larger scale following the success of this technique.
Mawson's geochemical rock chip, grab and channel sample database within
the 100 km2 Rompas project area now contains 1,171 samples which average 212 g/t gold and 0.8% U3O8. Of the 1,171 samples, 84 samples assay better than 100 g/t gold.
A new electromagnetic ("EM") ground survey completed at the Palokas
discovery has defined a subsurface 30 m wide by 300 m long conductor coincident
with and immediately below the widest zone of continuous gold
mineralization found at Rompas to date. This EM anomaly is part of a
larger 2,500 m long conductor defined by airborne geophysics.
On a more detailed scale, shallow drilling and trenching from South
Rompas has defined a coherent mineralized trend where 24% of all trench and drill assays grade greater than 100 g/t gold.
Mr Hudson states, "We continue to build our business in the Nordic
countries around Rompas, a project we consider to be potentially one of
the world's most exciting district scale gold discoveries, hosting
high-grade, near surface native gold mineralization, across multiple
prospects over a large area of 100 km2. We will maintain our exploration momentum and focus on shareholder
interests by continuing to control overheads and investing their
capital in the ground. We have confidence in our people and our
projects to expand our business via exploration success."
The extensive data collected from Rompas during the last 3 field seasons
has provided an excellent understanding of the exploration potential.
Mawson has collected a total of 2,808 surficial soil and till samples
over an area exceeding 55 km by 30 km. Sample spacing has ranged from
1 km to 250 m. Known gold mineralization correlates well with
surficial soil anomalies and many untested surface targets remain over
a larger area (Figures 2 and 3).
Surface prospecting, using radiometric methods as a pathfinder for gold,
have defined high-grade gold mineralization over a 100 km2 area, where less than 5% of rock outcrops. Mawson's geochemical rock
chip, grab and channel sample database over this large area now
contains 1,171 samples which average 212 g/t gold and 0.8% U3O8. Of the 1,171 samples, 84 samples assay more than 100 g/t gold. Gold
values range from 33,320 g/t gold to <0.001 g/t gold and U3O8 values from 49.5% to <4 ppm. Channel samples are considered
representative of the in-situ mineralization sampled, while grab
samples are selective by nature and are unlikely to represent average
grades on the property (Figure 2 and 3).
The completion of a LIDAR airborne survey at the end of 2012 gives
Mawson's field geologists the ability to prospect and map Rompas much
more rapidly and effectively. With this new technology, outcrops that
previously took weeks to locate and then map in 2011 and 2012, can now
be identified and mapped in days.
Other sampling previously not reported includes a heavy mineral
orientation program at South and North Rompas. Five non-selective, 5
litre heavy mineral samples were collected, with one from South Rompas
returning one of the largest accumulations of gold nuggets ever
identified within a heavy mineral sample from the Fennoscandian
Shield. This sample contained 5,000 gold nuggets, with 40-50 gold
grains in the 0.5-2 mm fraction. Other samples included one sample
up-ice direction with 18 nuggets, 100 m north-west of the last outcrop
in North Rompas (Figure 4). The three other samples contained 100, 1,000 and 100 nuggets
respectively. Eighty additional regional heavy mineral samples have
been collected and will be processed to further test this as a suitable
method for locating further blind gold mineralization.
This work suggests Rompas is shaping up at all scales and 58 gold
anomalous target areas from surficial sampling and prospecting have
been identified within the broad Rompas area for follow up during the
summer of 2013.
Over the past 11 months Mawson has drilled 8,164 m in 90 holes at
Rompas. This comprised 2,462.8 m in 29 drill holes at North Rompas;
2,436.2 m in 29 drill holes in the northern block at South Rompas;
2,504.3 m in 24 holes within the southern block at South Rompas; and
761.5 m in 8 drill holes at Northern Rajapalot.
To date, the most encouragement has come from the northern block of
South Rompas, with both prospect scale shallow drilling and trenching
defining a coherent mineralized sequence. A typical cross section
through South Rompas is shown in Figure 5. South Rompas is characterized by gold mineralization constrained to
one specific host rock type (metabasalt) within a broader uranium
halo. Within this halo the:
Top 24% of all trench and drill assays above the lower cut of 0.5 g/t
Au or 100 ppm U3O8, have a grade of 100 g/t or more and the top 24% of all intersections
have a grade of 0.42% U3O8 or higher;
Top 25% of drill intersections only have a grade of 7.7 g/t or higher;
The highest grade drill hole intersection is 3,540 g/t gold over 1 m.
The highest grade uranium intersection is 3.6% U3O8 over 0.6 m in a trench. The highest grade drill intersection grade of
0.7% U3O8 over 1.0 m;
Mineralization in the vein system, to date, is characterized by narrow
intersection widths of 1-2m with an average of 0.9 m thickness;
Drilling, to date, has been shallow with 46% of intersections at 20 m
down hole depth or less;
11 out of 13 holes drilled in 2013 winter drill program at South Rompas
had at least one intersection that exceeded lower cut 0.5 g/t gold or
100 ppm U3O8.
Mawson is now evaluating further drilling or bulk sampling programs in
order to best determine the gold grade in this nuggetty and high-grade
During the winter, 48.3 km of magnetic and 35.3 km of electromagnetic
("EM") ground-based geophysical surveys were completed at Rajapalot (Figure 6). The most significant feature identified is a 300 m long by 30 m wide
conductor under the widest zone of continuous gold mineralization found
at Rompas to date at Palokas, where rock chip sampling across a
strongly altered outcrop averaged 13.4 g/t gold and 226 ppm uranium
over 9 m. In total at Palokas, 17 grab samples from a 170 m by 55 m
area averaged 20.7 g/t gold with a maximum of 85.0 g/t gold and minimum
of 0.0 g/t gold. The style of mineralization is sulphidic and of a
disseminated or replacement style which is amenable to EM geophysics
and differs from the low sulphide, vein style observed at original
Rompas discovery area.
A more widely spaced regional airborne electromagnetic survey flown over
a broader area also shows a coincident conductor at Palokas and
suggests this conductor continues to further mineralized areas over a
strike of 2.5 km to the Rumajarvi prospect area where 32 grab samples
over a 700 m by 250 m area averaged 85.6 g/t gold with a maximum of
1,380.0 g/t gold and minimum of 0.0 g/t gold.
Approximately 80% of Mawson's highest priority targets at Rompas are
within European Union defined biodiversity areas (Natura 2000) where
the Company is not yet permitted to drill (Figure 1). Natura 2000 defined areas cover 30% of Northern Finland. These
targets include the extensive disseminated style mineralization
discovered in 2012 at Rajapalot. Although Mawson holds the mineral
rights within these areas, drilling is not permitted until the Company
completes an environmental program (a Natura Assessment) and a modified
claim decision is granted by the Finnish authorities. It remains
critical to the development of the Rompas project that the Company
works in conjunction with the Finnish authorities to gain systematic
drill access to the best exploration targets in the shortest possible
Mawson commissioned Golder Associates of Finland to complete a year-long
Natura 2000 Assessment that mapped and reported in detail the floral
distribution and natural habitat types of the area. The assessment also
defines the impact that Mawson's exploration work will have on the
biodiversity values. The key consultant who performed all the mapping
was one of the biologists who mapped the Rompas Natura 2000 area when
it was defined in the late 1990s. He is widely considered as the
biodiversity expert for the project area. The report stated that at
this stage of exploration, a managed program will have no significant
environmental effects on the area. The Company has started discussions
with the environmental authorities with respect to this study. The
competent authority, the Centre for Economic Development, Transport and
the Environment in Lapland, have up to 6 months to comment on the
report, and provide their feedback to the mining authorities (TUKES).
TUKES are the ultimate decision-makers to modify Mawson's claims to
allow drilling in the Natura 2000 areas. The Company does not expect a
decision before early 2014.
Over the last year Mawson also commissioned the Geological Survey of
Finland to complete a detailed first stage of a base line geochemical
water survey. The aim of the study was to investigate the
pre-exploration state of the area. Groundwater, surface water
(streams), stream sediments and mosses were studied. Groundwater
samples were collected from the wells of the study area, including
drilled wells, excavated wells and springs used as household water.
Samples of stream water and organic stream sediments were collected
from streams in a natural state. Samples of mosses were also
collected. Physical-chemical properties (anions and elements) and
concentrations of radon (Rn-222) of waters, and elements of the stream
sediments and mosses were analyzed. It was found surface, groundwater
and moss quality was good and elemental concentrations can be regarded
as background values, while variations can be interpreted to be related
to the natural variation in the area. Follow-up surveys will be carried
out at three year intervals.
The Company has continued to regularly meet all stakeholders including
local groups, municipalities and administrative bodies to update them
on the Company's work plans. For the most part the stakeholders have
been supportive of the Company's work programs and how it has dealt
with compliance issues, however there have been some objections and
opposition to the Company's work plans and environmental efforts,
and where differences have arisen the Company has worked to address the
