Nuinsco Announces Positive Metallurgical Test Results From Prairie Lake

Processing provides enhanced rare earth, tantalum and niobium grades in concentrate

TORONTO, ONTARIO--(Marketwire - Oct. 19, 2009) - Nuinsco Resources Limited ("Nuinsco") (TSX:NWI) ( announced today that it has received positive results from metallurgical testing of surface samples from its 100% owned, Prairie Lake Project in northwestern Ontario. The testing indicates that Dense Media Separation and Magnetic Separation processing are a means of producing concentrates from Prairie Lake containing mineralization of sufficiently elevated grade to be of potential economic interest. This mineralization includes rare earth elements (REE) (including lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd) and yttrium (Y)), niobium (Nb), tantalum (Ta), phosphorous (P) and uranium (U).

"The initial results clearly demonstrate that rock from Prairie Lake can be upgraded to produce concentrates with enhanced content of mineral commodities of economic interest such as phosphorous, niobium, tantalum, and rare earth elements," said Paul Jones, President. "In particular the non-magnetic concentrate returned mean values of 9.4% P2O5, 0.29% Nb2O5, 35.9 ppm Ta, and 2808.2 ppm combined rare earth elements. The next step is to optimise a process to specifically suit the Prairie Lake rocks to provide better separation of the mineral species to further enhance the recoveries."

Additional sample process testing is being conducted to determine if floatation concentration produces even better results. Samples have been selected from drill core and submitted for these tests. Results will be reported upon receipt.

The mineralization at Prairie Lake is hosted in a very large carbonatite complex (2.8 km2 at surface) which provides an enormous target and source for rare earth elements, niobium and other commodities. In particular, niobium and phosphorous values from drill core, beginning at surface, compare favourably with those identified by Commerce Resources Corp. ("Commerce Resources") at its Upper Fir cabonatite in BC. By way of comparison, average grades for the 17 diamond drill holes completed by Commerce Resources during 20061 at Upper Fir were 0.11% Nb2O5, and 3.69% P2O5 and 0.018% Ta2O5, whereas the weighted average of all core samples drilled at Prairie Lake from 1969 to 2008 is 0.13% Nb2O5, and 3.93% P2O5 and 0.003% Ta2O5.

Twelve samples were collected from surface pits excavated by backhoe from the carbonatite and ijolite rocks that comprise the Prairie Lake Complex. Ten of these samples, weighing between 37.5 kg and 42.8 kg each, were submitted to the Kennecott mineral processing laboratory in Thunder Bay for dense media separation and magnetic separation processing. Three sub-samples were produced from each of the original ten samples submitted and geochemical analyses were conducted by Activation Laboratories in Thunder Bay.

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. The Prairie Lake Project hosts a near-surface historic (non-NI-43-101-compliant) resource of over 180,000 tonnes grading 0.09% U308 (1.656 lb/tonne) and 0.25% niobium identified in limited exploration dating from the mid-1960s. The Prairie Lake Carbonatite intrusion is a vast exploration target that forms a prominent circular hill. Anomalous uranium mineralization is widespread throughout the intrusion in association with the minerals pyrochlore, uranpyrochlore and betafite.

The resource estimate quoted herein is based on prior data and reports obtained and prepared by previous operators and the Company. The Company has not completed the work necessary to verify the classification of the mineral resource estimate. The Company is not treating the mineral resource estimate as NI 43-101 defined resources verified by a qualified person. The historical estimate should not be relied upon. This property requires considerable further evaluation which Nuinsco's management and consultants intend to carry out in due course.
