Nuinsco Resources Limited announced the filing of a National Instrument 43101 ("NI 43101") Technical Report (the "Technical Report") for the initial Mineral Resource Estimate ("MRE") for the Prairie Lake Critical Minerals and Phosphate Project located near Terrace Bay, Ontario ("Prairie Lake" or the "Project"). 871.8 million tonne Inferred Mineral Resource including 2.01 kg/t total rare earth oxides ("TREO"), plus niobium and phosphate. 15.6 million tonne Indicated Mineral Resource including 1.67 kg/t TREO, plus niobium and phosphate.

ubstantial potential remains to expand and upgrade the MRE. Situated in Ontario, Canada, a stable, mining friendly, jurisdiction - a potential key North American source of Critical Minerals to meet an anticipated enormous expansion in demand for such products. Project is exceptionally close to the TransCanada Highway, rail, electrical power, and shipping infrastructure.

The Prairie Lake MRE was conducted in accordance with NI 43101 standards of disclosure and the CIM Definition Standards for Mineral Resources and Mineral Reserves (May 2014) and Best Practices (2019). The Project benefits from a location in a politically stable jurisdiction; is exceptionally well located near available rail, road, shipping, and power infrastructure; and is ideally placed in North America with respect to current supply chain concerns for critical minerals. The mineralization of economic interest contained within the Prairie Lake complex occurs at surface and extends to unknown depths below the deepest drilling yet conducted (circa 525 metres vertically).

There is no indication that mineralization diminishes with depth and is known to occur at surface throughout the extents of the complex. Prairie Lake consists of 46 mineral claims covering an area of ~630 ha and is superbly located, easily accessed by an allweather road from the TransCanada Highway located 28 kilometres to the south. The MRE for the Project is based on 73 inclined diamond drill holes performed between 1969 and 2010 totalling 12,180 metres.

Additionally 2,068 metres of surface trenching is included in the MRE. A total of 5,409 drill core samples and 1,042 channel samples are incorporated into the MRE, excluding QA/QC samples. A composite length of 1.5 metres was used and they were capped as follows: 1,850 g/t Nd2O3, 250 g/t Pr6O11, no cap Sc2O3, 1% Nb2O5, 14% P2O5, 3,700 g/t CeO2, 1,700 g/t La2O3, 520 g/t Sm2O3, no cap Ta2O5 and 570 g/t Y2O3.

Grade interpolation was undertaken with the ID2 method on 10m x 10m x 10m blocks. Indicated Mineral Resources were classified within a 55m x 55m x 40m search ellipse and three drill holes while Inferred Mineral Resources were classified in two passes with a 110m x 110m x 80m search ellipse with two drill holes and subsequently a 220m x 220 m x 160m search ellipse with one drill hole. Historical drill core analyses were performed by Xray Assay Laboratories (Don Mills, Ontario) and Bondar Clegg and Company Ltd. (Ottawa, Ontario).

All analyses since 2007 have been performed at Activation Laboratories in Ancaster, Ontario (ISO/IEC 17025:2005); samples were delivered to the Activation Laboratories facility in Thunder Bay (ISO/IEC 17025:2005), Ontario for preparation and onward delivery to Ancaster.
