MGX Minerals Commences Drilling at Longworth Silica Project; Targeting High Purity Quartzite Mineralization within Snow Zone

VANCOUVER, BRITISH COLUMBIA / July 19, 2017 / MGX Minerals Inc. (“MGX” or the “Company”) (CSE: XMG / FKT: 1MG / OTC: MGXMF) is pleased to report a nine hole diamond drill program is underway at the Company’s Longworth Silica Project (“Longworth”) in British Columbia. The drill program will target a near surface, 4.5-hectare mineralized zone known as the Snow Zone (“Snow Zone”) to a depth of 90 meters. Longworth is listed as one of the top silica occurrences throughout the Province of British Columbia by the BCGS (Simandl, 2014) and was previously controlled by Consolidated Silver Standard Mines (“Silver Standard”) for 25 years.

Exposed bedrock samples collected from the Snow Zone by MGX’s Vice-President of Exploration, Andris Kikauka (P. Geo). assayed up to 99.34% silicon dioxide (SiO2) (see press release dated May 30, 2016). These levels are consistent with Silver Standard’s results and meet the chemical and thermal shock specifications required to be used as a primary feedstock for silicon metal smelting (Quartermain, 1986). End uses for silicon metal include semiconductors, solar panels and aluminum alloys.

The Snow Zone is part of the Company’s larger Longworth claim package that encompasses 1,198 hectares and consists of four distinct high purity quartzite zones across a collective strike length of 7,000 meters. Longworth is situated four kilometers from the Canadian National railroad mainline and power grid and accessible by a network of well-maintained logging roads.
