MGX Minerals Proposes Mine to Market ("M2M") Solar Energy Program for Canada

VANCOUVER, June 13, 2022 - MGX Minerals Inc. ("MGX" or the "Company") (CSE:XMG) (CNSX:XMG.CN) (FKT:1MG) (OTC:MGXMF) announces an initial proposal has been made to the Natural Resource Canada - Zero Emission Vehicle Infrastructure Program, for the purpose of directing Federal funds into a supply chain that provides for a domestic mine to market ("M2M") industrial solar product for Canadian energy infrastructure. The final plan is to be provided to governing parties of the First Nation, Municipal, Regional, Provincial and Federal as well as private sector solar and chemical partners with current M2M solar supply chain roles, for the purpose of forming a partnership (the "Partnership"). The purpose of the Partnership is for domestic availability of metallurgical grade silicon (3303# grade), upgrading, and component design for solar panels. The long term strategic goal is to provide low cost energy for internal Company use in silicon and magnesium processing, and the energy needs of First Nations and the Provinces and Territories of Canada.

Silicon

Metallurgical testing on an one ton sample from the Company's Gibraltar Silica deposit, located 95 kilometers north-east of Cranbrook, British Columbia, has indicated that the material is chemically suitable, as medium quality feedstock, for metallurgical-grade silicon. The one ton sample of quartzite from Gibraltar was shipped to an independent lab, Dorfner Anzaplan, for mineralogical analyses through X-ray diffraction analysis, chemical analyses through X-ray fluorescence spectroscopy, grain size distribution, mineral processing analysis, automated optical sorting, and thermal stability testing. The sample was crushed and screened into fractions between 20-120 mm for evaluation of applicability of these fractions as feedstock for metallurgical-grade silicon production. Results indicate that the material, after comminution and classification fraction, is of high initial purity (99.5 wt.-%), making the fraction chemically suitable as medium quality feedstock material for metallurgical-grade silicon metal production.

Gibraltar Silica

The Gibraltar Silica Property is located approximately 95 kilometres northeast of Cranbrook, BC. It covers a sedimentary clastic-carbonate rock package located near the confluence of Kootenay and White River. Sedimentary rocks generally have a north-northwest strike, but locally a north-northeast strike is prominent. Minor folding was noted in the carbonate sequence immediately adjacent to quartzite unit. Two westerly dipping thrust faults (Hay, Carter, 1988) are believed to run north-south close to the eastern edge of the Gibraltar property.

The Company has completed 5 drill holes at Gibraltar. The holes were located at the Red Cloud (Gibraltar) quarry that was operated on a small scale in 1967. The objective of the drill program was to test subsurface dimensions of high purity quartzite. The Gibraltar North Zone has been sampled, mapped and the area located about 400 meters north of the south zone, represents the continuation of the Mount Wilson Formation quartzite.

Koot Silica

The Koot Silica project is located proximate (5 kilometres) to Gibraltar. The 2018 core drilling and geochemical sampling was carried out to evaluate mineral potential in a 180 meter X 600 meter area (elongated northwest), located in the east portion of the Koot Silica property in the area where quartzite is well exposed on a low relief ridge. This coincides with the general area where ComInco Ltd. Drilled 8 holes in 1981. Exploration drill results from 2018 are as follows:

Processing

The processing of silica to silicon is a relatively simple process primarily dependent on high quality feedstock. Additional ingredients of wood chips, for spacing, and metallurgical grade coal, to reduce energy requirements and assist in even heat transfer are required. Both of these ingredients as well as electricity, at a globally competitive price, are available in the region. The materials are top loaded into a submerged arc furnace ("SAF") and heated to 1600 degrees Celsius melting the silica which is then bottom poured into bricks which are ground into 3"- 4" pieces for shipping. MGX has issued a global request for quotation ('RFQ') and received initial quotations from major furnace manufacturers with minimum specification of 1,000 tonnes per month.
