Nuinsco Announces Seventh Intersection of More than 100m of Continuous Critical Elements & Phosphate Mineralization at Prairie Lake

Toronto, September 1, 2021 – Nuinsco Resources Limited (“Nuinsco” or the “Company”) (CSE: NWI) today announced an intersection of 118.6m of Critical Elements and phosphate mineralization obtained from on-going drill-core sampling at its 100%-owned Prairie Lake project near Terrace Bay, Ontario.

“We continue to see extensive intersections of elements of significant economic interest from the Prairie Lake carbonatite complex. This most recent result brings to seven the number of drill-holes identified by this sampling program with intercepts of 100m or more of Critical Elements – of note this most recent intersection contains 118.6m grading more than 2000g/t combined REEs (see below for tabulated individual REE values)” said Paul Jones, Nuinsco’s CEO.  “The intersections received to date have been obtained from near surface mineralization that the Company is expecting to use for a resource estimate, there is no indication that mineralization diminishes with depth and the seven intersections reported to date occur over an interval of 530m in the Southwest Area Exploration Target (see map and table below), highlighting the potential scope and value of the mineralization on the project.    

As previously reported the mineralization in the Prairie Lake intrusion occurs at surface and extends to unknown depth below the deepest drilling conducted to date (circa 500m vertically). The Prairie Lake complex hosts a suite of elements of economic interest identified as Critical Elements defined under the Canadian Minerals and Metals Plan (“CMMP”) contained within a very large domain of mineralized rock that is extremely favourably located from a logistical perspective with rail, road, shipping, and power infrastructure already in place.  The project hosts a number of elements and compounds of economic interest including those for which demand is projected to substantially increase and for which secure supply chains are sought.

Sampling of diamond drill core from holes NP0806 produced continuous mineralized intersections of 118.6m (from 6.4-125m) of niobium (Nb), tantalum (Ta), phosphate (P2O5), and rare earth elements (REE) including lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd) and yttrium (Y) – analytical results are tabulated below.  Eighteen drill-holes have been sampled to date, focussing on drill-holes collared to intercept the Southwest (SW) Area (see map below) – this domain measures 1km in length and is between 150m and 750m wide at surface. The SW Area alone hosts an Exploration Target (“ET”) of 435-530 million tonnes with grades as tabulated in the “Prairie Lake ET” table below.  The sampling will provide information to support the Company’s goal of establishing a mineral resource at Prairie Lake.

The Prairie Lake project consists of 46 mineral claims covering an area of ~630 ha. Logistically Prairie Lake is superbly located, with ready access to power, road, rail and shipping infrastructure; it is easily accessed by an all-weather road from the TransCanada Highway 28 kilometres to the south. The mineralization identified is entirely contained within the Prairie Lake carbonatite complex; the ET of 515-630 million tonnes is defined by 59 diamond drill holes with grades as tabulated below.

All samples were analysed by Activation Laboratories (ActLabs) in Ancaster, Ontario. Samples were analysed for a whole rock and trace element ICP analytical package as well as for niobium, tantalum, and zirconium oxides using a fusion XRF method. An internal Quality Control Quality Assurance (QAQC) program was implemented with four QAQC samples (blanks and reference standards) added into the sampling stream.

2 A full description of methodology used to estimate the Prairie Lake Project Exploration Target is contained in the Technical Report dated 30 November 2018 prepared by P&E Mining Consultants Inc.that is filed on SEDAR.  The potential quantity and grade of the ET is conceptual in nature and there has been insufficient exploration to define a mineral resource. It is uncertain if further exploration will result in the discovery of a mineral resource. There is no National Instrument 43-101 – Standards of Disclosure for Mineral Projects preliminary economic assessment in respect of the Prairie Lake ET.
