Leading Edge Materials Produces High Purity

Nepheline Co-Product from Norra Karr Rare

Element Project

/CNW/ -

Leading Edge Materials Corp.

("

Leading Edge Materials

")

or ("

the "Company

") (

TSXV: LEM

) (

OTCQB: LEMIF

) (

Nasdaq First North: LEMSE

) is pleased to

provide results from recent mineral processing test work carried out on samples from the Norra Kärr

rare earth element ("REE") project in Sweden. Work was undertaken on the nepheline/feldspar by-

product material, as part of a program to capture value add opportunities that Norra Kärr provides

beyond REEs. A Pre-Feasibility Study completed on Norra Kärr in 2015 presented REE as the only

economic product but identified a range of opportunities to convert much of the mined material into

products for sale while minimizing the environmental footprint of the project.

Based on extensive previous testwork, the first stage of mineral processing (beneficiation) for Norra

Kärr is magnetic separation, which partitions magnetic (iron-rich) minerals including those carrying

REEs from non-magnetic minerals. Magnetic separation is a chemical free process where material

is classified by response to a magnetic field.

The non-magnetic minerals at Norra Kärr include nepheline and feldspar, which are highly sought

industrial minerals for ceramics, glass manufacture, plastics, cosmetics, paint and building products.

Value is placed on a range of factors that include alkali content, aluminum content and iron content

which together determine melting conditions and the degree of sample whiteness. When added to

ceramic and glass products, nepheline lowers the melting point of silica both reducing the amount of

energy required for glass production and increasing hardness and durability. Nepheline is also

favoured as a paint additive as it is silica-free, and in

Russia

is used as a source for aluminum.

Recent testwork completed at the Geological Survey of

Finland

("GTK") on a bulk sample originally

collected under the EURARE Horizon2020 project delivered promising results. Nine tests were

completed where the nepheline/feldspar sample was passed through a second phase of magnetic

separation under varying conditions to remove any remaining iron impurity. This "clean-up" stage

was highly effective in removing iron, which was lowered to a level consistent with peer materials

that are sold within

Europe

today. Once sub-20 micron material was screened out, iron oxide

("Fe2O3") content of 0.1% was achieved with an iron oxide (ppm) to aluminum (%) ratio ranging

from 45 to 50.

Norra Kärr is a nepheline syentite intrusion and the presence of potentially economic nepheline and

feldspar has been recognised for many years. The project was held by Swedish mining company

Boliden AB during the 1970s and 80s with a view to produce nepheline, feldspar and zirconium. As

magnetic separation was not a well-established technology at the time, saleable materials could not

be economically produced.

Europe

is the largest global market for nepheline and feldspar, with supply from mines including

Stjernøy in northern

Norway

, western

Turkey

and northwestern Russia.

Blair Way

, President and CEO, states, "

Our research focus is to optimize all parts of the Norra

Kärr project, both financially and environmentally. Nepheline and feldspar together comprise

around 60% of the rock at Norra Kärr, and finding a market for these industrial minerals is a very

important step in our target to achieve a zero waste mine design. This latest round of research

has produced samples that appear equivalent to product sold in

Europe

today, and we are very

encouraged by this latest increase in resource efficiency of Norra Kärr.
