Nuinsco Reports Balance of Trenching Results From Prairie Lake Rare Metals Project

Results Demonstrate Strong Niobium & Phosphorous Mineralization With REEs and Tantalum


- All trenching results from Prairie Lake have now been released; positive results continue to advance this well located rare metals project

- Results include grades up to 6.14% phosphorous, 1.08% combined rare earth elements, 0.27% niobium and 13ppm tantalum

- Easy, year-round site access

- Superior location relative to infrastructure near Marathon, Ontario

- Mineralization has been proven to be amenable to upgrading using low-cost flotation – first tests upgraded phosphorous to 23% and REEs by 10 times

Next Steps:

- Complete assays from 2010 diamond drilling program

- Process testing to evaluate production of a niobium concentrate

- Incorporate trenching and drill results to update current 330 million-360 million tonne ETMI

TORONTO, ONTARIO--(Marketwire - April 11, 2011) - Nuinsco Resources Limited ("Nuinsco") (TSX:NWI) ( today further advanced its Prairie Lake rare metals project in Northern Ontario with the release of the balance of trenching results. Assays include grades up to 6.14% phosphorous (P2O5), 1.08% combined rare earth elements (REEs), 0.268% niobium (Nb2O5) and 13ppm tantalum (Ta2O5).

"This trenching program demonstrates strong niobium and phosphorus mineralization, with REEs and tantalum, over significant sampling lengths, indicating the potential to substantially increase the scale of the 330-360 million tonne Exploration Target Mineralization Inventory (ETMI) reported previously," said Paul Jones, President. "For instance, the 343.3m long Raspberry Hill Trench includes a 250m interval grading 0.117% Nb2O5 and 3.09% P2O5, while in the 687m long Grouse Trench a 116.7m interval grades 0.1% Nb2O5 and 2.42% P2O5."

The 2010 trenching program consisted of four trenches, mainly on parts of the Prairie Lake Complex that to date have seen little systematic sampling (see map attached). The results of the Dragonfly Trench were reported on March 10, 2011; the remainder of samples from the trenching program are reported here.

Grouse Trench: One of two trenches excavated in the NE quadrant of the Prairie Lake project. The results for the Grouse Trench include individual analyses of up to 9.89% P2O5, 0.423% Nb2O5 and 1.1% combined REEs (La+Ce+Sm+Nd+Y).

Raspberry Hill Trench: Excavated ~ 200m north of the Grouse Trench in the NE quadrant of the project. Of the 231 samples from the Raspberry Hill Trench, 58% returned assays of greater than 0.1% Nb2O5 (14% of all samples ≥ 0.2% Nb2O5). Results included individual analyses of up to 6.98% P2O5, 0.352% Nb2O5 and 0.48% combined REEs.

Wollastonite Trench: Excavated in the SE quadrant of the complex. The trench includes two East-West segments which branch out from the Wollastonite Showing. Sampling was completed only on the East branch, known as the Trailside Trench, which extends for 71.5m. Both branches were excavated for the purpose of defining the extent of the Wollastonite Showing.

Results included individual analyses of up to 11.26% P2O5, 0.265% Nb2O5 and 0.446% combined rare earth elements (REEs), and an intersection of 4.352% P2O5 and 0.157% combined REEs over 169.5m.

Complete assays from each of the trenches can be found on the Company's website at

Given the significant scale of the mineralization identified at Prairie Lake to date, Nuinsco is expanding its program of process testing that has shown that the mineralization, easily mineable with simple quarry methods, can be upgraded to produce a concentrate containing more than 23% P2O5 using low cost flotation methods (see press release dated February 4, 2010). This program is being expanded to evaluate production of a niobium concentrate in the next round of tests.

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. In addition, a 330 million-360 million tonne National Instrument 43-101-compliant Prairie Lake ETMI1, announced by news release on January 13, 2010, is based on only 12% of the total surface area of the Prairie Lake project, demonstrating the huge scale and potential economic significance of this multi-commodity deposit. The ETMI estimates known mineralization at between 330 and 360 million tonnes averaging 3.5% to 3.7% P2O5 and 0.12% to 0.14% Nb2O5 (1.2 to 1.4 kg/tonne). In addition to phosphorous and niobium, the suite of minerals of economic significance includes tantalum (Ta), uranium (U) and REEs (1,490-1,536 ppm combined, including lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd) and yttrium (Y)).

1 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.
