TASMAN EXPANDS OTANMÄKI RARE EARTH ELEMENT PROJECT IN FINLAND
VANCOUVER, Sept. 14
VANCOUVER, Sept. 14 /CNW/ - Tasman Metals Ltd. ("Tasman" or the
"Company") TSXV - TSM; Frankfurt - T61; Pink Sheets - TASXF. Mr
Mark Saxon, President & CEO, announces the Company has increased its
claim holding at the Otanmäki rare earth element (REE) project in
central Finland. Tasman has acquired a 100% interest in additional claim
applications and claim reservation applications, such that the Otanmäki
project now totals 10,954 hectares in size. The Otanmäki project lies
in a historic mining district 450 km north of the capital Helsinki, with
excellent infrastructure including railway access within 2 km of the
During a compilation and review of historic data, numerous mineralized
boulder trains were identified at Otanmäki, the interpreted bedrock
sources of which are now are secured within the expanded claim and claim
reservation area. Data from 44 mineralized boulders, sampled by
previous claim holder Rautaruukki Oy between 1982 and 1985 gave the
results provided in the table below. Note that only 6 of the 16 REE's
were assayed by Rautaruukki Oy, including only 2 of the higher value
heavy REE's (Eu2O3 and Y2O3).
Boulder samples are typically described as quartzite or syenite. Tasman
geologists have followed up this information with additional boulder
sampling and petrology; the results are awaited.
"The high average grade of these mineralized boulders is encouraging, in
particular as mineralized quartzite of this style has not been
intersected in drilling on the property to date" said Mark Saxon,
Tasman's President & CEO. "The high yttrium grades suggest the possible
enrichment of the higher value heavy rare earth elements, which shall be
determined once Tasman's sampling data are returned. Our exploration
program is focused on identifying the sources of these boulders, as well
as following up REE mineralization encountered in previous drilling.
The Otanmäki project is showing strong potential for REE mineralization,
and is again supported by the excellent network of road and rail that
characterizes Tasman's portfolio".
As described in a Tasman press release dated 26thApril 2010,
the Otanmäki project secures for Tasman two REE - niobium (Nb) -
zirconium (Zr) prospects, named Katajakangas and Kontioaho.
Fifty nine diamond drill holes for a total of 8,862 metres have been
drilled within the claimed area. REE's at Katajakangas and Kontioaho are
present as fergusonite, allanite and lesser columbite and xenotime
within a metasomatic altered interval of quartz-feldspar schist.
Better drill intersections at Katajakangas include:
Furthermore, Tasman has collected restricted 0.5 m samples from historic
Katajakangas and Kontioaho drill core, to better understand the REE
distribution. Of note a sample from R-21 at Katajakangas returned a
total rare earth oxide (TREO) grade of 3.27% with 17% of the TREO being
HREO. Individual metal values included 1.3% CeO2, 0.55%
Nd2O3, 0.1% Sm2O3, 117 ppm Eu2O3,
839 ppm Gd2O3, 132 ppm Tb4O7,
725 ppm Dy2O3, 370 ppm Er2O3
and 0.33% Y2O3.
REE consumption is growing, being essential in the production of
hybrid/electric cars, solar panels, wind turbines, compact fluorescent
lighting, high-energy magnets, mobile phones and computers. Tasman hold
numerous claims and claim applications across mining friendly regions in
Scandinavia with potential for REE's, and is well placed as the European
Union is actively supporting policies to promote the domestic supply of
REE's to secure high-tech industry.
Samples submitted by Tasman Metals Ltd were analyzed by the ME-MS81
technique by ALS Chemex Ltd's laboratories in Pitea, Sweden and
Vancouver, Canada, where duplicates, repeats, blanks and known standards
were inserted according to standard industry practice. Where over-range
for ME-MS81, Zr was determined using the ME-XRF10 technique. The
qualified person for the Company's exploration projects, Mark Saxon,
President and Chief Executive Officer of Tasman and a member of the
