Nuinsco to Continue Metallurgical Studies at Prairie Lake

Nuinsco Resources Limited ("Nuinsco" or the "Company")(TSX:NWI) (www.nuinsco.ca)
today reported that work will commence immediately on a metallurgical program to
explore the recovery of pyrochlore in concentrate from its 100%-owned Prairie
Lake phosphorus - rare metals project in northwestern Ontario. Pyrochlore, a
niobium-bearing mineral, occurs throughout the Prairie Lake carbonatite complex
and constitutes a significant potential economic component to the
multi-commodity mineralization of the project. The phosphorus-bearing mineral
apatite and rare earth elements ("REEs") in both apatite and rare earth-bearing
minerals such as ancylite further demonstrate the potential economic viability
of this project which is remarkable also for the scale of the mineralization
(currently at 515-630Mt in a 43-101 compliant ETMI) and superb logistics and
location. 


The niobium test work will be conducted by Corem in Quebec City, the laboratory
which has completed other metallurgical test work on the Prairie Lake
mineralization. Approximately 300-400kg of material will be used in the tests
which will assess the effects of grinding, gravity separation, magnetic
separation, flotation and reagents on pyrochlore concentrate production. As part
of the study, the potential for a magnetite-iron concentrate will also be
examined. The study is expected to take six to eight months to complete.


Widely occurring in the rocks at the Prairie Lake carbonatite complex at a grade
of 0.09-0.11% Nb2O5 (from 43-101 compliant ETMI) is the niobium-bearing mineral
pyrochlore. The niobium content of the rock at Prairie Lake is sufficiently high
to make the production of a niobium by-product a distinct possibility. Niobium
is used in structural steels where the addition of small amounts imparts
strength. These alloys are principally employed in the automotive industry,
where their greater strength allows for lighter structure and improved energy
efficiency. Niobium is also used in tubular steels for gas pipelines, while
super-alloys containing niobium are widely used in aircraft engines and as bone
replacements in medicine. In other applications, niobium is used in the
manufacture of high refractive-index lenses and electronic capacitors and in
super-conducting niobium-titanium wire used in such devices as magnetic
resonance imaging (MRI) machines used in healthcare and particle accelerators,
and as catalysts for producing bio-fuels from vegetable crops. 


About Prairie Lake 

Located about 45 kilometres northwest of Marathon, Ontario, Nuinsco's Prairie
Lake property covers the entire 2.8 km2 (at surface) Prairie Lake carbonatite
complex and is easily accessible from the TransCanada Highway. In January, 2012,
Nuinsco bought back a 2% production royalty making the property royalty-free.


The NI-43-101-compliant ETMI (see news release issued October 26, 2011) is 515 -
630 million tonnes grading between 0.09-0.11% Nb2O5 (0.9 to 1.1 kg/tonne) and
3.0-4.0% P2O5 - making Prairie Lake one of the world's ten largest carbonatite
hosted niobium deposits (and in North America second only to the Iron Hill
Project in Colorado, USA, in contained tonnes - the grade at Prairie Lake is
however greater). The current metallurgical work establishes the project as a
substantial, recoverable, phosphorus inventory. The suite of minerals of
potentially economic significance also includes tantalum (Ta), uranium (U) and
REEs (including lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd) and
yttrium (Y)). The ETMI was undertaken by Eugene Puritch, P.Eng. and Antoine
Yassa, P.Geo of P&E Mining Consultants Inc. of Brampton, Ontario.


All exploration work at Prairie Lake is supervised by Laura Giroux, P.Geo,
Senior Geologist, who acts as Nuinsco's Qualified Person under National
Instrument 43-101. Ms. Giroux has reviewed and approved the technical contents
of this news release. The potential quantity and grade of the ETMI is conceptual
in nature and there has been insufficient exploration to define a mineral
resource. It is uncertain if further exploration will result in the discovery of
a mineral resource.

expected consequences to, or effects on Nuinsco. Factors that could cause actual
results or events to differ materially from current expectations include, among
other things, failure to successfully complete financings, capital and other
costs varying significantly from estimates, production rates varying from
estimates, changes in world copper and/or gold markets, changes in equity
markets, uncertainties relating to the availability and costs of financing
needed in the future, equipment failure, unexpected geological conditions,
imprecision in resource estimates, success of future development initiatives,
