- Large Landholding: Permits covering over 1.7 million acres of brine-bearing formations throughout the Province
- Infrastructure: Permits located within and around oilfields; areas fully serviced with wellheads in place
- Partnerships: Agreements in place with major oil and gas operators to conduct well sampling
- Historic Assays: Permits cover a majority of the highest reported levels of lithium-bearing brine throughout the Province (1)
(1) All assays referenced are from the geoScout Oil & Gas Industry database as reported by well operators and monitored by the Government of Alberta.
Sturgeon Lake Oilfield
The Sturgeon Lake project is located in the Fox Creek area of west-central Alberta approximately 85 kilometers east of the city of Grande Prairie. The project encompasses over 132,000 hectares and represents the portfolio’s most advanced project.
Devonian-aged wells at Sturgeon Lake produce excessive amounts of brine in comparison to petroleum due to the mature nature of the oilfield where increased pumping is required to produce crude oil.
MGX has successfully concentrated lithium from heavy oil evaporator blowdown wastewater originating from the Sturgeon Lake oilfield using its rapid recovery process.

Geological units of Alberta range in age from Archean to Recent and are exposed as broad northwesterly trending belts, which decrease in age towards the southwest (Hamilton et al., 1999).
Precambrian rocks are exposed in the northeast and form the basement for a thickening wedge of Phanerozoic strata of the Western Canada Sedimentary Basin (WCSB) that reaches a maximum thickness of about 6,000 m in front of the Cordilleran fold-and-thrust belt to the southwest.
The crystalline basement rocks of northern Alberta represent the westernmost part of the Canadian Shield and have been assigned to more or less distinct continental slivers accreted to the composite Churchill province during the assembly of western Laurentia (~2.0 to 1.8 Ga; e.g., Hoffman, 1988; Ross et al., 1994); or to a more uniform continental fragment that was separated from and welded back to the Churchill province (Burwash et al., 1994, 2000).
Formation waters within the Devonian tend to be enriched in lithium. These formation waters are pumped to the surface in large volumes as waste products associated with oil and gas production.
The Devonian Winterburn-Woodbend, and Elk Point groups contain over 50% and 23% of Western Canada's initial established recoverable oil and gas reserves, and accounts for 54% and 34% of Western Canada's cumulative production oil and gas to date (Hay, 1994).
Mineralization consists of Li-enriched Na-Ca brines hosted in aquifers within Devonian carbonate reef complexes predominantly of the Woodbend-Winterburn groups (Red Deer; South Peace River Arch; and Fox Creek groups of permits) and Elk Point Group (Southeast group of permits).
Lithium values of up to 140 mg/L Li are reported, historically, from the AER oil and gas well database and Government studies (Hitchon et al., 1995; Eccles and Jean, 2010; Huff et al., 2011, 2012).
