Nuinsco Resources Limited Reports New Analyses from Prairie Lake Critical Minerals Project
27.02.2024 | The Newswire
Expands Mineralized Domain by Hundreds of Metres Highlights:
- New, widespread, and strongly anomalous rare earth element (“REE”), niobium, and phosphate mineralization.
- Analyses demonstrate grades of REE, niobium, phosphate comparable to those of mineral resource estimate (“MRE”).
- Significant expansion of strong, near-surface mineralization to the north of the mineral resource estimate.
Toronto, Feb. 27, 2024 – Nuinsco Resources Limited (“Nuinsco” or the “Company”) (CSE:NWI), (FRA:NJX) today 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 extension of strong mineralization of economic interest, as observed in the MRE, in this large domain near the north contact of the Prairie Lake Complex has significant implications for potential expansion of resources at the Project,” said Paul Jones, Nuinsco’s CEO. “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.

CRBT – carbonatite, PYX – pyroxenite, FEN – fenite, MAF – mafic,
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)).
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.

A full description of methodology used to estimate the Prairie Lake project Mineral Resource Estimate is contained in the NI 43-101 compliant Technical Report, effective date 31 May 2022 prepared by P&E Mining Consultants Inc. that is filed on SEDAR.
1. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
3. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could potentially be upgraded to an Indicated Mineral Resource with continued exploration.
3.1. The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.
5. US$ Metal prices used were $80/Kg Nd2O3, $80/Kg Pr6O11, $1,500/Kg Sc2O3, $50/Kg Nb2O5, $250/t P2O5, $1.35/Kg CeO2, $1.35/Kg La2O3, $3.50/Kg Sm2O3, Nil$/t Ta2O5 and $13.00/kg Y2O3, 0.78 FX all with combined process recoveries and payables of 50%, except P2O5 at 75%.
6. The constraining pit optimization parameters were C$2.50/t mining cost for all material, C$25/t process cost, C$5/t G&A cost and 45-degree pit slopes with a C$30/t NSR cut-off.
