VANCOUVER, Feb. 6, 2012 /CNW/ - Mawson Resources Limited ("Mawson") TSX - MAW; Frankfurt - MRY. Mr Michael Hudson, President & CEO, announces new results from the 2011
exploration program at the Company's 100% owned Rompas project in
Key points include:
A new zone of mineralization defined under thicker glacial soil with
grab samples from individual one metre deep pits assaying 557ppm,
147ppm and 201ppm gold within a zone extending over a 30 metre strike;
Continuity of lower grade gold and uranium mineralization further
established, highlighting mineralized trends;
New geophysics demonstrates gold mineralization is hosted by a
chargeable sequence which extends under cover away from known gold
Further bonanza gold grades from grab samples assay up to 33,200ppm
A new zone of mineralization has been defined late in the field season
at the southern extension of North Rompas under thin glacial till.
Grab samples taken from three separate one metre deep (hand dug) pits
returned 557ppm Au & 0.8% U3O8, 147ppm Au & 36.8% U3O8 and 201ppm Au & 0.1% U3O8 within a zone extending along strike over 30 metres under thin cover
(Figure 1). Due to the thicker till in the area only one metre hand
dug pits were able to access the weathered bedrock zones which were
subsequently grab sampled. One additional grab sample, interpreted to
be located 20m to the north in a parallel structure assayed 7,630ppm Au and 22.4% U3O8 (Figure 1).
Importantly, in the southern extension of North Rompas, continuity of
lower grade mineralization has been demonstrated over an area of 110
metres along strike and 90 metres width (Figure 1). Extent of known
mineralization is only limited by thick soil cover where bedrock cannot
be reached by radiometry nor hand digging due to current permit
restrictions. The new zone is located 300m south of the northern
extension of North Rompas zone where continuity was previously
established between mineralized zones (Figure 1), as reported in the
Mawson press release dated 31 October, 2011.
One grab sample at South Rompas, located 4.6km to the south, returned 33,200ppm Au and 56.6% U3O8 (Figure 2), which to date represents the highest grade sample yet taken
at Rompas. This sample was taken from a boudin in a vein that occurs
within the known extent of mineralization. Grab samples are selective
by nature and are unlikely to represent average grades on the property.
In addition, Mawson recently completed a 22 line km gradient array IP
geophysical survey at North and South Rompas. This survey highlighted
a chargeable host sequence that correlates with mineralized areas in
both North and South Rompas. The chargeable sequence is far more
extensive under areas of shallow till and soil cover that are too deep
to be tested by surface sampling (Figures 1 and 2).
Mr Hudson states: "Rompas continues to deliver with grade, continuity
and scale. Further discoveries and evidence for continuity of
mineralization at surface over considerable distances augurs well for
the prospectivity of this exciting new mineral district. Additionally,
the recent IP geophysical survey clearly highlights the host sequence
at Rompas. The chargeable sequence is shown to continue extensively
undercover away from areas where high grade gold and uranium
discoveries have been made."
The Rompas mineral system is hosted by metabasalt, dolomite,
calc-silicate, dolerite and volcaniclastics, all part of the
Palaeoproterozoic Perapohja Schist Belt. These rocks have undergone at
least two major deformation events, leading to a locally strong
schistosity (oriented 320-340 degrees) and metamorphism up to
amphibolite-grade resulting in diopside-tremolite-actinolite
assemblages in the calc-silicate rocks.
Gold and uranium mineralization at Rompas is hosted by a
quartz-calc-silicate vein array and related alteration selvages. The
calc-silicate veins (amphibole-pyroxene-quartz-carbonate ±gold,
uraninite) and alteration selvages (biotite-amphibole-K-feldspar) have
been metamorphosed to amphibolite facies, following a structural
episode of flattening within high strain zones. It is interpreted that
the veins are an early (pre-structuring) vein array, but that the
bonanza-grade mineralization is likely a result of the structuring and
metamorphism. Interestingly, lower grade gold (1-20ppm Au) with weakly
anomalous uranium (1-40ppm U) is known to occur outside the high-grade
pods, but still within the veins and/or alteration selvages. The
spectacular bonanza gold and uranium grades are generally contained in
pods of calcite and amphibole, often associated with boudinaged "ladder
veins" within the more extensive vein system, indicating they could be
local upgraded remobilizations from the veins.
Due to the lack of detailed work that has been done on this relatively
new discovery, little is understood about the nature of the
mineralizing controls. In any event, it would appear that the
exploration target is a large, bulk-tonnage vein system that may be
genetically related to a granitoid complex that occurs a few kilometers
to the north of the property. The possibility of finding potentially
economic high grade vein structures must also be considered.
Mawson holds 833 claims and claim applications for 75,340 hectares at
the Rompas Project. A total of 110 exploration claims that cover a
surface area of 10,580 hectares and form the core claims at Rompas were
granted on October 31, 2010 but do not come into legal force until
after a standard appeal process. Therefore sampling, to date, has been
restricted to low impact digging and trenching by hand through soil to
access bedrock for diamond saw channel and grab sampling.
Mawson samples were prepared by ALS Chemex Ltd's laboratory in Pitea,
Sweden and analyzed by Au-ICP21, ME-MS41u, PGM-ICP27 and ME-MS61u
techniques by ALS Chemex Ltd's laboratory in Vancouver, Canada and
Saskatchewan Research Council using standard ICP partial and full
digestion and fire assay methods. The qualified person for Mawson's
Finnish projects, Mr Terry Lees, VP Exploration for Mawson and Fellow
of the Australian Institute of Geoscientists has reviewed and verified
the contents of this release.
