MGX Minerals Advances 110,000 Acre Petrolithium Project Paradox Basin, Utah Canadian Stock Exchange:XMG.CN

(MENAFNEditorial) VANCOUVER, British Columbia, Dec. 15, 2017 (GLOBE NEWSWIRE) -- ('MGX' or the 'Company') (CSE:XMG) (OTCQB:MGXMF) (FKT:1MG) is pleased to report that the initial ground survey is nearing completion in preparation for a detailed 3D seismic survey of its Utah Petrolithium project (the 'Project'). The survey of the Project includes approximately 9,000 source points. This model will outline subsurface geological formations and structures favorable for accumulations of oil and gas as well as lithium brine bearing formations.

The Project is located next to the Lisbon Valley oilfield located within the Paradox Basin, Utah which has shown historical brine content as high as 730 ppm lithium (Superior Oil 88-21P) and past production of oil exceeding 50 million barrels. The Company's cumulative Project land position comprises over 110,000 acres of oil and gas leases and 118,000 acres of largely overlying mineral claims, including 80,380 acres of unitized Federal, State and Private lands within the Blueberry Unit ('Blueberry') where MGX controls the overwhelming majority of mineral claims. This represents the first large scale integrated petroleum and lithium project ever developed in the United States.

NFLi-5 Rapid Lithium Extraction System
MGX and engineering partner PurLucid Treatment Systems ('PurLucid') are nearing completion of the first commercial scale rapid lithium extraction plant and are currently in flow and pressure testing. MGX expects delivery and deployment in January 2018 (). This system is capable of processing up to 750 barrels per day (120 cubic meters) and serves as the commercial platform for the first 7500 barrels per day (1200 cubic meters) now in fabrication. This technology has been extensively tested in pilot plant phase since July 2017 on all types of lithium bearing brine throughout the Company's extensive project portfolio including high hydrocarbon evaporator blowdown (EBD) wastewater from SAGD oilsands production, traditional oil and gas wastewater, traditional lithium brine, and high magnesium wastewater concentrate from mine tailings among other sources throughout North America. As MGX's Paradox Petrolithium project advances, systems will be deployed for hydrocarbon separation and mineral extraction. The Project relies heavily on MGX-PurLucid patented and patent-pending water handling and rapid lithium extraction technology capable of processing complex brines in conjunction with oil and gas development that produces a clean water by-product aimed at mitigating water handling and disposal cost and providing an innovative clean water solution to the oil and gas industry. It has been suggested that Paradox Basin unconventional oil and gas development has been hindered by high total dissolved solids and water handling challenges and costs.1

Integrated Petrolithium Engineering
Initial engineering studies have been completed by SigmaCubed of Denver, Colorado modelling of simultaneous (brine / oil and gas) production scenarios aimed at drawing brine and oil from a single well. Reservoir simulations were run for the different scenarios to determine the sensitivity of the results to the input assumptions. There are three main variables – lateral horizontal length (feet), net reservoir height (feet) and permeability (millidarcies). A base case was run for a vertical well. Production rates (BWPD) were then calculated for different combinations of these three variables. For the purposes of this study, a 1,500-psi pressure differential drawdown at the perforation interval was assumed. A pressure drawdown across perforations can be achieved by various different production methods (i.e. rod pump, gas lift, hydraulic pump, jet pump, etc.). The study found that it did not matter how the pressure differential is achieved, reservoir conditions will ultimately determine production volumes. Also, for the purposes of this study, the tubing size was limited to one case (2 7/8' O.D.) primarily because the 2 7/8' tubing x 5 1/2' production casing configuration is one of the most common wellbore configurations utilized by the petroleum industry. Upon reviewing the results of this study, it become increasingly apparent of the multitude of variable combinations resulting from the study of just one tubing size. The results of this study can be ratioed up or down to obtain relative production volumes for 2 3/8' or 3 1/2' tubing strings.

Produced water density, oil API gravity and water oil ratios were found to have negligible effects on total production volumes. The biggest effect these variables had would be in the fluctuation of the producing fluid level in the wellbore. For the purposes of this study, a full column of 100% petroleum brine water weighing 11.0 ppg was assumed.

Assumptions

10 md permeability
55' net h
7,000' TVD
2 ⅞' tubing to 7,000' TVD MD
4 ½' liner in lateral 7,000' to TD
1,500 psig pressure differential
Drawdown across perforations

Additional engineering work will focus on the effect of large diameter casing and related costs on a per barrel basis starting with 7 ½' and consideration of techniques and scale currently utilized in geothermal brine wells.

Lisbon Valley and Paradox Basin Geology
The Lisbon Valley Field has approximately 140 wells. According to production statistics, as reported by the Utah Department of Natural Resources, Oil, Gas and Mining Division, cumulative lifetime production within the Lisbon Valley oilfield has totaled 51.4 million barrels of oil as of June 2017 ('Oil Production by Field, Utah Department of Natural Resources, Division of Oil, Gas and Mining'; June 2017; ). The Paradox Basin has been noted by the USGS as having one of the largest undeveloped oil and gas fields in the United States ('Assessment of Oil and Gas Resources in the Paradox Basin Province…'; USGS; 2011; ). MGX is currently earning a 75% working interest in the Project, with the remaining interest primarily controlled by a private Utah corporation (the 'Paradox Partner'). The Paradox Partner has been engaged by MGX as subcontracted operator of the Project ().

The Project is host to National Instrument (N.I) 51-101 estimated prospective resources (the 'Estimate') consisting of leasehold and royalty interests in San Juan County, Utah and Miguel County. Colorado. The estimate was prepared by the Ryder Scott Company, L.P. ('Ryder Scott'), an independent qualified reserves evaluator within the meaning of N.I. 51-101 - Standards of Disclosure for Oil and Gas Activities ('NI 51-101'), with an effective date of June 30, 2017. The Estimate was prepared in accordance with N.I. 51-101 and the Canadian Oil and Gas Evaluation Handbook.

Qualified Person
The technical portions of this press release were prepared and reviewed by Andris Kikauka (P. Geo.), Vice President of Exploration for MGX Minerals. Mr. Kikauka is a non-independent Qualified Person within the meaning of National Instrument (N.I.) 43-101 Standards.

MGX may decide to advance its petrolithium projects into production without first establishing mineral resources supported by an independent technical report or completing a feasibility study. A production decision without the benefit of a technical report independently establishing mineral resources or reserves and any feasibility study demonstrating economic and technical viability creates increased uncertainty and heightens economic and technical risks of failure. Historically, such projects have a much higher risk of economic or technical failure.
