VANCOUVER, April 4 /CNW/ - Tasman Metals Ltd. ("Tasman" or the "Company") (TSXV:TSM)
(Frankfurt:T61) (Pinksheets:TASXF). Mr Mark Saxon, President & CEO, provides an update on the metallurgical
research, drilling and environmental monitoring underway on the Norra
Karr heavy rare earth element (REE) project. Norra Karr is the only
NI43-101 compliant REE resource in mainland Europe.
SGS Minerals Services of Canada are completing mineralogical
characterization, concentrate preparation and hydrometallurgical
testing on a 100kg sample of representative Norra Karr mineralization.
To date, QEMSCANTM, electron microprobe and XRD (x-ray diffraction) has been applied to
characterise mineralogy and distribution of REE's and other potentially
"This first set of robust QEMSCANTM mineralogical results are encouraging, demonstrating that the ore
mineralogy of the Norra Karr deposit is simple, and those ore minerals
are liberating efficiently during crushing", said Mark Saxon, President
& CEO. "This mineralogical knowledge is being applied to the initial
phases of concentrate preparation, and roast-leach hydrometallurgical
processing that are now underway."
QEMSCANTM results confirm that the principal REE and zirconium bearing phases are
zirconium silicates. Eudialyte is most abundant zirconium silicate
comprising 4.3% of the 100kg sample, whilst secondary is catapleiite
comprising 2.5%. Zircon and other REE phases are present in only trace
amounts. Other minerals in the sample are dominated by Na-Al silicates
(36%), plus nepheline/microcline (31%) and clinopyroxene (24%).
Element deportment studies are in progress, and will be reported when
final results are available. However, microprobe analyses on 13
eudialyte grains indicated an average content of 5.0% TREO* ((total
rare earth oxide) * in this instance, analysis is for partial TREO
only, comprised of Y2O3 + La2O3 + Ce2O3), 12.4% Zr2O and 0.75% Nb2O3.
The liberation and association characteristics of the zirconium
silicates after crushing were examined. Particle liberation describes
the degree of separation of minerals-of-interest from other minerals,
based on the 2 dimension mineral-of-interest area percent. Perfect
liberation therefore equals 100%. Liberation analysis of the Norra
Karr sample indicated that in crushed material where 80% passed -150
μm, 79% of zirconium silicates were well liberated (where ≥80% of the
mineral-of-interest is separated from other minerals). This is
considered to be a high and encouraging degree of liberation.
The calculation of exposed surface area of the zirconium silicates after
crushing indicates that a large portion of grains (up to 94% of the
mass) had a surface exposure area greater than 50%. This well exposed
surface area suggests good potential for recovery, as the minerals of
interest are well exposed for chemical attack and breakdown, the
metallurgical effect of which must be tested with extensive research.
In Sweden, the Norra Karr Phase 3 drill program is ongoing, with 2,746m
completed in 17 holes (NKA11043 in progress). The objective of this
drill program is to infill sections to 100m spacing, test the deeper
parts of the mineralized intrusion and obtain additional drill core for
ongoing metallurgical testing. Drilling is proceeding well with the REE
mineralized intrusion having been intersected in all drill holes. The
mineralized intrusion has now been intercepted to a maximum down hole
depth of 298.8m in drill hole NKA11040, which ended in the intrusion at
the limit of the available drill rods. The maximum down hole depth
prior to this drill program was 152.5m. Assay results are pending.
In addition, the Company has retained independent consultants to
initiate environmental monitoring of water quality, flora and fauna at
the Norra Karr project site and surrounding area with the objective of
gathering adequate baseline information to be used in support of
a filing for a Mineral Lease application.
About Tasman Metals Ltd.
Tasman Metals Ltd is a Canadian mineral exploration and development
company focused on Rare Earth Elements (REE's) in the European region
and is listed on the TSX Venture Exchange under the symbol "TSM". REE
demand is increasing, due to the metals unique properties that make
them essential for high technology and environmentally-beneficial
applications. Since over 95% of REE supply is sourced from China, the
European Union is actively supporting policy to promote domestic supply
of REE's, to ensure the security of high-tech industry. Tasman's
exploration portfolio is uniquely placed, with the capacity to deliver
"high-tech" metals from politically stable, mining friendly
jurisdictions with developed infrastructure.
The Company's Norra Karr project in Sweden is one of the most
significant heavy REE resources in the world, and the only NI43-101
compliant REE resource in mainland Europe. With a TREO (total rare
earth oxide) cut off of 0.4%, the Inferred Mineral Resource comprises
60.5 million tonnes grading 0.54% TREO and 1.72% ZrO2 (zirconium
oxide), with 53.7% of the TREO being the higher value HREO (heavy rare
earth oxide). The resource is unusually low in radioactive metals
relative to peer projects, with less than 15 ppm each of uranium and
