Nuinsco Resources Limited announced analytical results from geological mapping and sampling conducted in the previously little-explored northern contact area of Prairie Lake Critical Minerals and phosphate project located near Terrace Bay, Ontario ("Prairie Lake" or the "Project"). The Project has amongst the world's highest known light rare earth element content in apatite and contains a host of other REE bearing minerals including monazite, bastnaesite, carbocernaite/burbankite, and ancylite, as well as niobium-bearing pyrochlore, and phosphate mineralization. The field work was conducted during the summer and autumn of 2023 and focussed on the northern part of the Prairie Lake Complex (the "Complex") near the little-explored north contact.

Outcrop is near non-existent in the work area, so the field crew prospected likely sites of near-surface bedrock exposure. A total of 25 pits were excavated to successfully access bedrock, and 30 samples were collected for analysis. The field work demonstrates that the north part of the Complex is underlain by widespread carbonatite rock that extends north from the domains hosting the very significant mineral resource estimate tabulated below, currently comprising nearly 890Mt of identified Critical Minerals endowment.

Analytical results reported here demonstrate that grades obtained from the sampling are consistent with those of the MRE. The significance of this is the potential to extend, to the north, mineralization in similar host rock to the MRE, possibly significantly expanding the near-surface MRE. Potential extension of the MRE is supported by the analytical results, tabulated below, that demonstrate the presence of distinctly anomalous grades of rare earth elements, phosphate, and niobium.

The current MRE is already a very large endowment of vitally important Critical Minerals that are in constantly expanding demand as the world's economies transition towards low-carbon emissions. The further expansion of mineralization demonstrates that scope exists to increase resources to other currently untested areas in the north, west, and east of the Project. Given the current size of the MRE at the Project, this possible further expansion is of enormous significance for the secure supply of Critical Minerals in North America and beyond.

All samples were analysed by Activation Laboratories: samples were submitted to their facility in Thunder Bay, Ontario for preparation and forwarded to their facility in Ancaster, Ontario for analysis. Activation Laboratories is accredited under the Canadian Association for Laboratory Accreditation (CALA), ISO 9001:2015 and ISO/IEC 17025:2017. Samples were analysed for a whole rock and trace element ICP analytical package (QOP WRA/QOP WRA 4B2 Major/Trace Elements Fusion ICPOES/ICPMS) as well as for niobium, tantalum, and zirconium oxides using a fusion XRF method (QOP XRF Fusion (XRF)).
