Nuinsco Resources Limited announced that recent fieldwork and reinterpretation of historical data from the Prairie Lake Critical Minerals and phosphate project have combined to produce an updated interpretation of the geology of the Prairie Lake Complex (the "Complex") that expands, by approximately 70%, the carbonatite component of the Complex, potentially simplifying further development of resources. Prairie Lake, located near Terrace Bay, Ont., has amongst the world's highest known light rare earth element content in apatite and contains a host of other REE bearing minerals, as well as niobium-bearing pyrochlore, and phosphate mineralization. Metallurgical studies to date demonstrate that a clean phosphate concentrate, grading 26% P2O5 at 76% recovery with ample room for improvement, and with valuable rare earth element co-concentrate can be reliably produced from Prairie Lake feed.

Field work was conducted during the summer and autumn of 2023 on the northern part of the Prairie Lake Complex near the little-explored north contact. The resultant mapping and sampling, combined with re-evaluation of historic data, has significantly expanded the area of interpreted mineralized carbonatite rock domains at surface, increasing the carbonatite content of the Complex at surface by approximately 70%. This new carbonatite domain is at least 1.5 km long by 500m wide.

The importance of the updated interpretation is that is substantially reduces geological complexity and so simplifies ongoing evaluation of resource potential and metallurgical processing. The current MRE consists of the very significant Critical Minerals endowment, tabulated below, currently comprising nearly 890Mt. A simplified geology enhances the possibilities for resource enhancement with further work.

The Prairie Lake project contains a large, well-located resource of critical minerals in North America. It is a potential source of elements needed for applications in transportation, power distribution, green technologies and a host of other applications, including agriculture. It is of immense value to a secure critical minerals supply chain; a strategic concern identified by numerous governments in the recent past and addressed with incentives and programs to encourage development of the critical minerals sector.

The Project is located near the north shore of Lake Superior, putting it in close or easily accessible reach of: · The towns of Marathon, Terrace Bay and other affected communities - all able to supply a local, skilled workforce. All weather forest access road crossing the project and deposit. Paved Highways 17 and 11 to the south and north.

Canadian Pacific Railway and Canadian National Railway networks. High capacity (230kV) electrical power transmission line. 50km from the Marathon deep water port project.

Deep-water ports are also located at Thunder Bay and Sault Ste. Marie, able to handle ocean going ships. The Marathon airport.
