Nuinsco Expanding Geological Coverage at Prairie Lake Critical Minerals Project

(TheNewswire)

Toronto – TheNewswire - September 13, 2023 – Nuinsco Resources Limited (“Nuinsco” or the “Company”) (CSE:NWI) today announced that additional geological mapping and sampling is being conducted at its Prairie Lake Critical Minerals and phosphate project located near Terrace Bay, Ontario (“Prairie Lake” or the “Project”).

The field work is focussing on the northern part of the Prairie Lake Complex; an area that has seen little past exploration. The area is north of the domains hosting the very significant mineral resource estimate (“MRE”), as reported on 31 May 2022 and tabulated below, currently comprising nearly 890Mt of identified Critical Minerals endowment. The deposit has amongst the world’s highest known light rare earth element (“LREE”) content in apatite and contains other REE bearing minerals including monazite, bastnaesite, carbocernaite/ burbankite, and ancylite, as well as niobium-bearing pyrochlore.

“The extension of coverage outside the MRE is an important step in addition to the ongoing metallurgical studies at SGS-Lakefield Laboratory, environmental baseline evaluation and expansion of geological understanding of the Prairie Lake Complex,” said Paul Jones, Nuinsco’s CEO. “We are fully aware of the scope of the mineralization on the project, the potential for expansion of the MRE, and the possibility that domains of higher-grade mineralization exist within the MRE or for that matter elsewhere on the project outside of the existing resource. The attributes of the project are very favourable to development, and we are diligently conducting work to do so.”

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.

• 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.

Nuinsco Resources has over 50 years of exploration suc­cess and is a growth-oriented, multi-commodity mineral explora­tion and development company focused on prospective oppor­tunities in Canada and internationally. Currently the Company has three properties in Ontario – the high-grade Sunbeam gold property near Atikokan currently optioned to First Class Metals PLC, the large multi-commodity (phosphate, rare earth element, niobi­um, tantalum) Prairie Lake project near Marathon-Terrace Bay, and the Zig Zag Lake property (lithium, tantalum) near Armstrong also optioned to First Class Metals PLC. In addition, Nuinsco has an agreement for gold exploitation at the El Sid project in the Eastern Desert of Egypt.

Prairie Lake Project Pit Constrained Mineral Resource Estimate(1-6)

*TREO = Total Rare Earth Oxides: neodymium, Nd2O3 ; praseodymium, Pr6O11; scandium, Sc2O3; Cerium, CeO2; lanthanum, La2O3; samarium, Sm2O3; yttrium, Y2O3.

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.

Forward-Looking Statements

This news release contains certain "forward-looking statements." All statements, other than statements of historic fact, that address activities, events or developments that Nuinsco believes, expects or anticipates will or may occur in the future are forward-looking statements.
