Nuinsco Resources Prairie Lake Now Royalty-Free
TORONTO, ONTARIO--(Marketwire - Jan. 23, 2012) -
Nuinsco Resources Limited ("Nuinsco") (TSX:NWI) (www.nuinsco.ca) today
announced that it has purchased back the 2% production royalty on its Prairie
Lake phosphate and rare metals project in consideration for the issuance of
3,157,894 common shares of Nuinsco. The royalty was obtained by Stares
Contracting Corp. in 2001.
"The buy-back of this royalty enables Nuinsco shareholders
100% participation as the Company moves forward to capitalize on the
significant tonnage and tremendous upside potential at Prairie Lake," said
René Galipeau, Vice-Chairman and CEO. "Already the second largest deposit of
its kind in contained tonnes in North America, we know that the tonnage at
Prairie Lake has the potential to become much larger. The property is now
royalty-free as we await the results of the ongoing metallurgical evaluation
program."

The surrounding area of Nuinsco Resources Carbonatite section has
high potential for economical discoveries. Assays results from the Lab returned
grades of 1.07 % up to 3.27 % rare earth and up to 1.63% Nb205 - 20.6% P205,
0.12% U308 - 5.01% P205, 0.23% Zr, 0.10% Y, 10,600ppm La, 15,700ppm Ce, 1,490ppm
Pr, 4470ppm Nd, 710ppm Sm, 235ppm Eu, 502ppm Gd, 57.7ppm Tb, 247ppm Dy these are
only some of the rare earth elements on the property. Given the current market
conditions for rare earths and the urgency to find alternative sources, our
newly discovered targets do bear geophysical and geochemical signatures.
Also modern alluvium gold grains recovered from the property in
"Area 4" indicates the gold potential on the property.

Prairie Lake Carbonatite:
Heavy minerals associated with carbonatite were recovered from
several samples. Of particular interest is sample 16-MA-99. This modern alluvium
sample yielded a large number and variety of heavy minerals similar to those
recovered from the Prairie Lake Cabonatite. In addition, several other heavy
mineral types, also found at the Molycorp Pass Carbonatite in northern
California, were recovered. The Molycorp Mountain Pass Carbonatite is of
particular interest as it is a major supplier of rare earth metals to the world
and has been since the early 1950s. Barite, synchysite and bastnaesitite are the
3 important minerals associated with the California deposit which measures only
200-300 feet across. To test whether the mineral signature of the modern
alluvium sample were derived from the Prairie Lake Carbonatite, which occurs up
ice, 2 bedrock samples were taken close to the sample site. The minerals derived
from these bedrock samples confirmed that the modern alluvium mineral signatures
were local and similar to that reported from the Molycorp Mountain Pass
Carbonatite.
The Prairie Lake Carbonatite Complex is a quasi circular structure
with an approximate surface area of 10 km2 . The complex has been ace dated by
several investigators at l billion years.
Introduction:
The surrounding area of Nuinsco Resources Carbonatite complex has high potential for economical rare
earth deposits. Given the current market conditions for rare earth metals and
the urgency to find alternative sources.
The Prairie Lake property is adjacent
to the Prairie Lake Carbonatite Complex (PLCC). The PLCC lies at the
intersection of fractures subsidiary to the northern extension of the Big
Bay-Ashburton Fault (BBAF). The BBAF is deep seated, related to the Lake
Superior mid continental fault, and is considered to be a controlling structure
in the formation of the major alkaline intrusives at Prairie and Killala Lakes.
General Geology:
Regional Geologic Setting:
The Prairie Lake ring complex is an intrusive plug emplacing
continental shield Archean felsic igneous and metamorphic rocks. The complex is
spatially and age related ( see Gittens et al. f 1967) to the
nepheline syenite complexes of Coldwell to the southeast and Killala Lake to the
northeast. It is reasonable to assume that these complexes represent
differentiated segments of magma that have traveled in different paths bur that
have been generated from the same magma source. The differentiation in such
cases may be extensive such that the petrology of the complexes and economic
geology can show strong dissimilarities.
The Prairie Lake complex can also be seen to fall within the North
American Mid-Continent gravity high and the major regional Carb Structure which
includes several carbonatite complexes and extends for a distance of at least
800 km (seeErdosh,1979).
Economic Minerals and Potential:
The Prairie Lake carbonatite complex shows excellent economic
potential for several elements, most important of which are niobium and uranium.
These elements both occur in minerals of the pyrochlore group which are found in
the carbon-aptites, silicocarbonatites and ijolites. The composition of the
pyrochlores show local variations from uranium-rich uranium- pyrochlore and
betafite to the uranium impoverished species, pyrochlore. For a classification
of the pyrochlore system nomenclature the reader is referred to Hogarth (1977).
The uranium content of the pyrochlores does not appear to be depend ant on the
rock type. Of the pyrochlore group minerals (including the species pyrochlore,
uranpyrochlore and betafite), betafite is most frequently encountered in the
Prairie Lake rocks.
Recommendation:
Field work conducted by Rudy Wahl
(Prospector) has located multiple new occurrences of alkaline rocks with
significant REE values as well as elevated radiometric signatures. Tony
Mariano and Son visit the Prairie Lake area property in July 2011 and they
recommended to fly a closely spaced airborne radiometric & magnetic survey over
the Prairie Lake property, also Tony Mariano recommended that all the magnetic
lows under the swamps that surrounding the center carbonatite plug (Nuinsco
Resources property) on the Prairie Lake property to be drilled. The area around
Nuinsco Resources carbonatite plug has high potential to locate an rare earth
deposit.
Nuinsco Reports Significant Increase in ETMI at
Prairie Lake Project
1:48 EDT Wednesday,
October 26, 2011
TORONTO, ONTARIO--(Marketwire - Oct. 26, 2011) - Nuinsco Resources
Limited ("Nuinsco")(TSX:NWI)(www.nuinsco.ca)
today announced that the Updated Exploration Target Mineralization Inventory
("ETMI") at its easily accessible, Prairie Lake rare metals project in
northwestern Ontario has been increased to 515–630 million tonnes grading
between 0.09-0.11% niobium (0.9 to 1.1 kg/tonne) and 3.0-4.0% phosphorus (1.2
to 1.4 kg/tonne), making it one of the largest deposits of its kind in the
world.
"The ETMI increase places Prairie Lake
well within the ranks of the ten largest carbonatite-hosted niobium deposits
in the world, and in North America it is second only to the Iron Hill Project
in Colorado owned by Colorado Rare Earths Inc., in contained tonnes (the
average grade at Prairie Lake is however greater)," said Paul Jones,
President. "The increase follows from the incorporation into the ETMI of the
drill and trench results obtained from the 2010 work program that returned
widespread and extensive niobium (Nb2O5)
and phosphorus (P2O5)
analyses."
The significant size of the ETMI at
Prairie Lake, its location near existing infrastructure and transportation
networks, the relative ease with which it could be exploited from surface
using quarry methods and the continuing potential for expansion of the ETMI,
all point to Prairie Lake being an undervalued asset within Nuinsco's property
portfolio. In addition to niobium and phosphorus, the suite of minerals of
significant economic potential also includes tantalum (Ta), uranium (U3O8)
and rare earth elements (REE) (including lanthanum (La), cerium (Ce), samarium
(Sm), neodymium (Nd) and yttrium (Y)),
