Toronto, November 7, 2025 – TheNewswire - Nuinsco Resources Limited (“Nuinsco” or the “Company”) (CSE: NWI) today announced a non-brokered private placement of flow-through common shares (“Flow-Through Shares”) and common shares (“Common Shares,” collectively the “Private Placement”). Under the Private Placement, the Company could issue up to 100,000,000 Flow-Through Shares and/or Common Shares, dependent on investor demand, priced at $0.005. The Private Placement is expected to close on or about December 4, 2025.

 

Proceeds from the sale of Flow-Through Shares will be used to fund work to advance the Company’s Prairie Lake critical minerals project located near Terrace Bay, Ont.; proceeds from the sale of Common Shares will be used for future general corporate purposes.

 

Nuinsco’s focus project, Prairie Lake, is a critical minerals asset with a phosphate – rare earth element (“REE”) mineral resource estimate (“MRE”) of close to 900 million tonnes (15.6 million tonne indicated and 871.8 million tonne inferred, using a 2% P2O5 cut-off grade) - see MRE table below. Crucially, using an increased 5% P2O5 cut-off grade, as reported August 13, 2024, has led to the identification of a domain that comprises a 65 million tonne Inferred MRE sensitivity grading 5.9% P2O5 and a 1.2 million tonne Indicated MRE sensitivity grading 5.8% P2O5, within the existing MRE, and with coincident increase in REE co-concentrate grade. The presence of such a domain of higher-grade critical mineral endowment combined with a multitude of favourable characteristics – technical, logistical, geographic, and strategic necessity – may have great significance to the development of Prairie Lake.  

Metallurgical studies to date demonstrate that a clean phosphate concentrate, containing valuable REE co-concentrate, can be reliably produced from Prairie Lake rock. The Potential for niobium co-product is also apparent and is being investigated.

 

The elements found at Prairie Lake are essential for applications in transportation, power distribution and storage, steel fabrication, green technologies and agriculture, to name a few. The project boasts substantial, already established, logistical advantages, including easy access to:

 

• Nearby communities - all able to supply a local, skilled workforce. 

• An all-weather forest access road crossing the project and deposit. 

• Paved Highways 17 and 11 to the south and north respectively. 

• Canadian Pacific Railway and Canadian National Railway networks. 

• A high capacity (230kV) electrical power transmission line. 

• The Marathon deep water port project (50 km away), able to accommodate ocean-going ships. Deep-water ports are also located at Thunder Bay and Sault Ste. Marie, Ontario. 

• 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.

4. 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.
