Tasman engages ANSTO Minerals to expand metallurgical testing of Norra Karr heavy REE project

Tasman engages ANSTO Minerals to expand metallurgical testing of Norra Karr 
heavy REE project 
VANCOUVER, March 25, 2013 /CNW/ - Tasman Metals Ltd. ("Tasman" or the 
"Company") (TSXV:TSM) (Frankfurt:T61) (NYSE-MKT:TAS). Mr Mark Saxon, President 
& CEO, is pleased to announce that the Company has engaged the services of 
ANSTO Minerals of Australia (ANSTO) to support the next stage of Tasman's 
hydrometallurgical testing program on the Company's 100% owned Norra Karr 
heavy rare earth element (REE) and zirconium (Zr) project in Sweden. ANSTO is 
an Australian government owned research institution, widely acknowledged as 
the industry leader in all facets of REE mineral leaching, solution 
purification and precipitation. ANSTO has operated numerous large scale 
pilot and demonstration plants for REE. 
Highlights 


    --  Future mineral concentrate research to be completed by magnetic
        separation equipment manufacturers, to ensure a seamless
        transition to mine-scale equipment planning.  Prior test work
        by ANZAPLAN of Germany gave high recovery of REE in a low mass
        during combined flotation/magnetic separation tests, including
        more than 80% of the heavy REE's recovered in less than 30% of
        the original rock mass;
    --  Future hydrometallurgy research on Norra Karr to be completed
        by ANSTO, the industry leader in REE processing technology.
        Prior testing by GTK of Finland used an ambient temperature
        sulfuric acid leach and achieved better than 90% recovery of
        heavy REE's;
    --  Comminution test work is complete, demonstrating crushing and
        grinding requirements shall lie within the range of normal
        processing conditions;
    --  Eudialyte is the major REE-bearing mineral present, with
        accessory REE minerals identified only in minor or trace
        abundance;
    --  All major ore types are mineralogically indistinguishable when
        ground to 500 micron, suggesting geological variation across
        the ore body is unlikely to affect processing behavior;

"We are pleased to announce the engagement of ANSTO for our next phase of 
hydrometallurgical tests" said Mark Saxon, Tasman's President and CEO. "ANSTO 
is well known for its prior work on the major Australian based rare earth 
projects including Mount Weld (Lynas Corp) and Dubbo (Alkane Resources) and 
their involvement gives us the opportunity to most efficiently finalize the 
Norra Karr leaching - purification - precipitation circuits. The outcome of 
the work from ANSTO will be a key part of our Pre Feasibility Study and Pilot 
Plant tests."

ANSTO shall execute a series of leaching tests, extending and refining those 
completed to date by other laboratories. REE recoveries exceeding 80% have 
been achieved during previous tests using sulfuric acid under atmospheric 
temperature and pressure conditions. This leach test program is designed to 
maximize the recovery of the heavy REE's, reduce acid consumption, and 
constrain all remaining leaching variables. ANSTO has been provided with 
mineral concentrate prepared by Germany's ANZAPLAN (DORFNER Analysenzentrum 
und Anlagenplanungsgesellschaft mbH). The concentrate sample was prepared from 
drill core collected across the Norra Karr deposit and is considered 
representative. Results from the work with ANSTO will be used to provide 
process input into the company's ongoing engineering studies.

As previously reported, Tasman has completed extensive testing on production 
of a mineral concentrate, most recently with ANZAPLAN. Magnetic separation 
and flotation have proven to be the most effective techniques at separating 
the ore mineral eudialyte from various gangue phases. Tasman has now passed 
the research and process optimization role to the internal laboratories of 
magnetic separation equipment manufacturers Eriez Magnetics, Metso Minerals, 
Outotec and Allmineral. This engagement ensures that recovery is optimized, 
and that the mine-scale equipment requirements of the Norra Karr project are 
well understood by equipment manufacturers.

Furthermore, Tasman has recently completed comminution (crushing and grinding) 
studies to characterize Norra Karr ore. Work undertaken by Wardell Armstrong 
International in Truro, UK, lie within the range of normal milling conditions, 
as provided below:
    --  Crusher Work Index: 12.64 kW hr/tonne
    --  Rod Mill Work Index: 14.90 kW hr/tonne


--  Bond Ball Mill Work Index
  o 150µm: 12.85 kW hr/tonne
  o 106µm: 14.30 kW hr/tonne
  o 90µm: 15.21 kW hr/tonne 
--  Abrasion Index: 0.3050 
These comminution results will enable the design of the crushing and grinding 
circuits 
The Norra Karr project is one of the two NI 43-101 compliant REE resources 
within the European Union, both 100% owned by Tasman Metals Ltd. Norra Karr 
lies 15km NNE of the township of Gränna and 300km SW of the capital Stockholm 
in mixed forestry and farming land. The short time taken from discovery to 
ML application demonstrates the efficiency and advantage of operating in a 
jurisdiction with a strong and transparent Mining Act and a long term 
association with resource industries. The project is proximal to road, rail, 
power and operating ports, plus skilled personnel, minimizing the need for 
offsite infrastructure to be built by the Company. 
Norra Karr is one of the largest and most economically robust projects amongst 
its peers, due to the high contribution of the high value critical REE's 
(dysprosium (Dy), yttrium (Y), neodymium (Nd), terbium (Tb)). Substantial 
capital and operating cost benefits are provided by the existing 
infrastructure and the simple mineralogy that allows ambient temperature and 
pressure processing. Norra Karr's proximity and easy road access to European 
markets stands as a unique operating advantage for the project.

Cautionary Note to U.S. Investors Concerning Mineral Resources and Reserves. 
In this news release, the definition of "mineral resources" is that used by 
the Canadian securities administrators and conforms to the definition utilized 
by CIM in the "CIM Standards on Mineral Resources and Reserves - Definitions 
and Guidelines" adopted on August20, 2000 and amended December11, 2005. 
The standards employed in estimating the mineral resources referenced in this 
news release differ significantly from the requirements of the United States 
Securities and Exchange Commission (the "SEC") and the resource information 
reported may not be comparable to similar information reported by United 
States companies. The term "resources" does not equate to "reserves" and 
normally may not be included in documents filed with the SEC. "Resources" 
are sometimes referred to as "mineralization" or "mineral deposits." While 
the terms "mineral resource", "measured mineral resource", "indicated mineral 
resource" and "inferred mineral resource" are recognized and required by 
Canadian regulations, they are not defined terms under standards in the United 
States and normally are not permitted to be used in reports and registration 
statements filed with the SEC. The terms "mineral reserve," "proven mineral 
reserve" and "probable mineral reserve" are Canadian mining terms as defined 
in accordance with National Instrument 43-101 - Standards of Disclosure for 
Mineral Projects ("NI 43-101") and the CIM - CIM Definition Standards on 
Mineral Resources and Mineral Reserves, adopted by the CIM Council, as may be 
amended from time to time by the CIM. These definitions differ from the 
definitions in the United States Securities and Exchange Commission Industry 
Guide 7 ("SEC Industry Guide 7") under the Securities Act of 1933. Under 
Canadian rules, estimates of inferred mineral resources may not form the basis 
of feasibility or prefeasibility studies, except in rare cases. Disclosure of 
"contained ounces" in a resource is permitted disclosure under Canadian 
regulations; however, the SEC normally only permits issuers to report 
mineralization that does not constitute "reserves" by SEC standards as in 
place tonnage and grade without reference to unit measures. 
The estimation of measured, indicated and inferred mineral resources involves 
greater uncertainty as to their existence and economic feasibility than the 
estimation of proven and probable reserves. U.S. investors are cautioned (i) 
not to assume that measured or indicated resources will be converted into 
reserves and (ii) not to assume that estimates of inferred mineral resources 
exist, are economically or legally minable, or will be upgraded into measured 
or indicated mineral resources. It cannot be assumed that the Company will 
identify any viable mineral resources on its properties or that any mineral 
reserves, if any, can be recovered profitably, if at all. As such, information 
contained in this news release and the documents incorporated by reference 
herein concerning descriptions of mineralization and resources under Canadian 
standards may not be comparable to similar information made public by United 
States companies in SEC filings.
