Northern Shield samples 1.2% Cu, 0.35% Ni at Idefix

NORTHERN SHIELD SAMPLES 1.5% CU+NI AND 12.3 G/T PGE+AU FROM IDEFIX NI-CU-PGE PROPERTY, NORTHERN QUEBEC

A grab rock sample recently collected from a zone of disseminated sulphides on Northern Shield Resources Inc.'s 100-per-cent-owned Idefix copper/nickel/platinum group element property has assayed 1.2 per cent copper, 0.35 per cent nickel, 9.6 grams per tonne palladium, 2.4 grams per tonne platinum and 0.27 gram per tonne gold. Ground truthing and verification of VTEM (versatile time-domain electromagnetic) geophysical anomalies identified from a 2016 airborne survey were also undertaken during the very brief visit to the property.

Idefix is located approximately 80 kilometres west of Kuujjuaq, Nunavik, Northern Quebec. The property covers a seven-kilometre stretch of a gabbronorite sill complex that is primarily being explored for disseminated PGE/nickel/copper mineralization but also has many recognized features that suggest the presence of high-grade nickel/copper/PGE massive sulphide mineralization. The property was last drilled by the company in 2013 when reef-type and disseminated PGE sulphide mineralization was intersected over a five-kilometre strike length.

The grab sample is important as it provides proof-of-concept that higher concentrations of disseminated sulphides are present in the sill and that they can carry higher base metal and PGE grades. The grab sample contained approximately 10 per cent sulphides, suggesting that massive sulphides are not required to generate higher base metal grades. This is the highest base metal grade reported from Idefix and the grab sample was collected from the northern portion of the property, an area that was not the focus of exploration when the company was last actively exploring in 2012/2013.

"We revisited our data on Idefix over the last year and it reminded us that it is an exceptional project. It is unusual to see such continuous PGE mineralization over this large an area (60 by 5,000 metres). The re-evaluation also prompted us to focus more on the potential of a disseminated sulphide system, with good base metal grades along with the PGE, not just exploring for massive sulphides. This sample provides a proof of concept for this approach, although more exploration is required to properly evaluate the area.

"An update on the drilling program at Root & Cellar will be provided shortly," stated Ian Bliss, president and chief executive officer of Northern Shield.

Disseminated model

Previous drilling and surface sampling by the company delineated PGE mineralization over a five-kilometre strike length. Drill core grades averaged approximately 0.25 gram per tonne PGE plus gold over true thicknesses up to 60 metres, associated with very low base metal values. The mineralization has very low concentrations of sulphides averaging 0.5 per cent. A linear relationship between sulphide content and PGE grades is noted at Idefix, such that a tenfold increase in sulphides generally brings a similar order of magnitude increase in PGE grades.

Massive sulphide model

Sulphide globules up to two centimetres in diameter were observed in all 14 drill holes completed in 2013. Analyses by pXRF (portable X-ray fluorescence) show that the globules average 3.2 per cent copper, 1.9 per cent nickel and 23 grams per tonne palladium. The sulphide globules are interpreted to have originated from a pool of liquid massive sulphide when the magma was still molten. Such globules are known to be fragile and tend to disaggregate in the magma conduit due to turbulent flow, and, as such, the presence of many sulphide globules suggests that the source pool of sulphide magma is proximal.

Analysis, quality assurance/quality control and qualified person

Grab rock samples are single samples and by their nature are not representative of all mineralization encountered or expected to be found on the property. Samples were analyzed by ALS Global in Vancouver, B.C., for gold by fire assay and multielements by four-acid digestion and ICP-AES. All standards and duplicates by ALS Global meet targeted values. This news release was reviewed by Christine Vaillancourt, PGeo, the company's chief geologist and a qualified person under National Instrument 43-101.

About Northern Shield Resources Inc.

Northern Shield Resources is a Canadian-based company, known as a leader in generating high-quality exploration targets, that views greenfield exploration as an opportunity to discover a near-surface, Tier 1 asset at relatively low cost. The company implements a model-driven approach in exploration to reduce risks associated with early-stage projects for itself, its shareholders and the environment. This approach is what led to the discovery of an alkaline-related gold-silver-tellurium and porphyry copper system at the Root & Cellar project in Newfoundland.
