Highlights:

• Multiple high-grade phosphate drill intersections identified; define an extensive phosphate domain. 

• Domain exceeds 1200m length – abundant room for expansion. 

• High-grade domain occurs within the 900Mt mineral resource estimate (“MRE”) on the project. 

• High-grade phosphate within the MRE is a higher-value component that enhances potential viability. 

• High-grade phosphate translates into elevated rare earth element (“REE”) content. 

 

Toronto – TheNewswire - June 25, 2024 – Nuinsco Resources Limited (“Nuinsco” or the “Company”) (CSE: NWI), (FRA: NJX) today announced an expansion of the results from review and  reinterpretation of historic drill data (the “Study”) that establishes the presence of enriched apatite domains measured over hundreds of metres along a zone within the near 900Mt existing MRE (see MRE description below) at the Prairie Lake Critical Minerals Project (“Prairie Lake” or the “Project”). Phosphate grades are substantially higher than reported in the Company’s MRE dated May 31, 2022. The identification of such domains may have great significance to the development of the Prairie Lake Project and enhances its value.

Identification of high-grade apatite/phosphate mineralization in 22 diamond drill holes (see table below), with intersections up to tens of metres wide in a domain at least 1200m long, is a step-change in awareness of the attributes of the mineralization at the project, and particularly within the MRE.  Higher grade domains are higher value components of the MRE and allow greater versatility in planning and scheduling development of the resource should the project merit a production decision. The very large Critical Minerals MRE at the Project is enhanced by the identification of high-grade domains within it.   Ample room exists to expand the mineralized domain to other parts of the Complex with similar geology.

 

“High-grade phosphate zones at the Project further enhance its already significant potential as a North American source of much sought after Critical Minerals,” said Paul Jones, Nuinsco’s CEO. “The high-grade intersections occur within the existing 871.8 million tonne Inferred MRE and 15.6 million tonne Indicated MRE at the Project. Based upon our understanding of the geology of the Complex we believe there is substantial opportunity to expand the high-grade domains elsewhere on the project. To be clear though, the Prairie Lake Project is already a vitally important Critical Minerals asset. Further definition of high-grade phosphate domains will allow greater leeway in planning and developing the project.”

The Prairie Lake Project is located near Terrace Bay, Ontario. It is a very substantial resource of phosphate mineralization, 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. 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.

 

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.

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.
