Prairie Lake
Located about 45 kilometers northwest of Marathon, Ontario, Nuinsco's Prairie Lake property covers the entire 2.8 km2 surface area of the Prairie Lake Carbonatite Complex. The property is located just 28km north of the TransCanada Highway as well as the North Shore of Lake Superior, and is accessible year-round by gravel road.

Prairie Lake hosts an exploration target (ET) of 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). The areas included in the exploration target, which represent only ~30% of the total surface area of the Prairie Lake Complex, are areas that have been more intensively explored yet still lack sufficient diamond drilling to define a resource.

All of the mineralization is exposed at surface and could be exploited by simple quarrying methods. The suite of minerals of potentially economic significance also includes tantalum (Ta2O5), uranium (U3O8) and rare earth elements (REEs) (including lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd) and yttrium (Y))..

Nuinsco is undertaking metallurgical testing to evaluate the production of distinct niobium (Nb2O5) and fertilizer-grade phosphorus (P2O5) concentrates from Prairie Lake mineralization.

1 The potential quantity and grade of the exploration target 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.

The ET was undertaken by Eugene Puritch, P.Eng. and Antoine Yassa, P.Geo of P&E Mining Consultants Inc. of Brampton, Ontario. All exploration work is supervised by Paul Jones, P.Geo, President, who acts as Nuinsco's Qualified Person under National Instrument 43-101. Mr. Jones has reviewed and approved the contents of this disclosure. The potential quantity and grade of the ET 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.
