MGX Minerals Commences Pilot Plant Testing for Li-1 Lithium Recovery System

VANCOUVER, BRITISH COLUMBIA / August 1, 2017 / MGX Minerals Inc. (“MGX” or the “Company”) (CSE: XMG / FKT: 1MG / OTC: MGXMF) is pleased to report that engineering partner PurLucid Treatment Solutions (“PurLucid”) has commenced operational testing on the Li-1 lithium recovery unit at its testing facility in Calgary, Alberta. The Li-1 pilot plant is capable of processing 20 m3/day and will be expanded to increase throughput to 100m3/day. Initial testing is focused on lithium-rich brine samples obtained from MGX lithium and petrolithium properties and as well as oil & gas partners. Testing is currently underway to finalize technical specifications for contractual arrangements with industrial and oil and gas partners. In addition, MGX’s deployment plan continues to focus on the Company's land package of over two million acres of lithium brine mineral claims in North America.

“This system represents the physical and operational templates that move us from bench scale to the field and provide the engineering basis for large commercial systems (>1500 m3/day) we expect to deploy into MGX’s property and partner base,” said Jared Lazerson CEO of MGX Minerals Inc.

Concurrently with pilot plant testing, fabrication of a commercial-scale system capable of processing 200 m3/day is underway and expected to be ready for deployment in Q4 2017. Based on results of pilot plant testing, the Company plans to ship commercial-scale systems to sites in the US and Canada beginning in Q1 of 2018.

MGX and PurLucid have now fully integrated their respective technologies. The pilot plant separates impurities from oil and gas wastewater, allowing for lithium and magnesium extraction as well as reuse and repurpose of industrial water and brine.
