MGX Minerals Acquires Lisbon Valley Petro Lithium Project in Utah

Extraction of Lithium from Oil Field Brine
As previously announced, MGX and engineering partner PurLucid Treatment Solutions ("PurLucid") have successfully extracted lithium from oil sands wastewater (see press release dated January 3, 2017). The Company and PurLucid are now preparing for deployment of the pilot plant shortly with commercial scale deployment expected during the second half of 2017.

The pilot plant unit represents fully integrated technology combining MGX's patent pending lithium extraction process, which potentially reduces recovery times of lithium and other valuable minerals from 18 months to one day when compared with conventional lithium extraction, with PurLucid's patented water purification technology, which removes particulate and dissolved material including dissolved and emulsified oil, colloids and heavy metals.

Pilot Plant Optimization Update
Results from pilot plant optimization testing will be released shortly as part of the completion of the pilot plant. Lithium carbonate has been extracted from oil well production waste water at the Company's flagship Sturgeon Lake property. Results are currently under technical review and will be released shortly (see Figure 2).
