CALGARY, Alberta, Nov. 09, 2022 (GLOBE NEWSWIRE) -- LithiumBank Resources Corp. (TSX-V: LBNK) (OTCQX: LBNKF) (FSE: HT9) (“LithiumBank” or the “Company”) is pleased to announce the completion of the hydrogeological study from its 100% owned Kindersley Lithium-brine project (the “Kindersley Project”) located in southwest Saskatchewan, 160 km west of Saskatoon. The hydrogeological study was carried out by Matrix Solutions Inc. (“Matrix”).
Encouraged by two anomalous lithium brine samples collected from the Duperow Formation in 2017 by the Saskatchewan Geological Survey, LithiumBank established a strategic core position in December 2021. LithiumBank intends to collect samples from the Duperow Formation within the Kindersley Project area and use knowledge and experience derived from its Boardwalk Project in Alberta to fast track a National Instrument 43-101 (“NI 43-101”) technical report and future Preliminary Economic Assessment.
Highlights:
- Matrix assessed reservoir properties and aquifer deliverability within LithiumBank’ mineral leases and identified multiple zones of potential lithium brine production within the Duperow Formation add up to ~ 90 m in net pay at a 6% porosity cut off
- The Duperow Formation is an unconfined aquifer that measures up to 300 m within the area of the Company’s mineral leases comprising the Kindersley Project
- The Duperow Formation within LithiumBank's Kindersley Project area hosts a brine volume of 3.89 km3 at a 6% porosity cut off
- Expected brine production from the Duperow Formation is up to 1,600 m3 per day
- Two brine samples from an area of the Duperow Formation adjacent to the Kindersley Project collected in 2017 by the Saskatchewan Geological Survey, returned 78 mg/L and 70 mg/L lithium
LithiumBank engaged Matrix to conduct an in-depth geological and hydrogeological study of the Company’s 41,014 ha (101,347 ac) of mineral leases located 5 km north and east of the town of Kindersley, Saskatchewan (see Figure 1 below). The study is a compilation of all available data in the area from historic and ongoing hydrocarbon activities. The purpose of the study is to provide the level of detail required in preparing a NI 43-101 compliant technical report and ultimately, to evaluate the Kindersley Project’s potential for future lithium-brine production.
The Duperow Formation which is stratigraphically similar to the Leduc Formation in Alberta was the focus of Matrix’s study as it is actively used as a water source and has shown enriched concentrations of lithium as compared to other basinal aquifer concentrations in the area. The Matrix study indicates hydrogeological characteristics including porosity and permeability at the Kindersley Project are positive and consistent with historical long term production rates in proximal wells and a cumulative historical brine production of 3.3 million m3. In addition to active water wells, there are several injection wells in the Duperow Formation with injection rates over 2,000 m3/day. Based on the available data, Matrix expects a single well in the Duperow Formation may be capable of producing brine at a daily rate of up to 1,600 m3.
Within the area of the Company’s mineral leases comprising the Kindersley Project, Matrix utilized all available drill stem tests (DSTs), historical production rates, fluid chemistry analysis, formation top picks and logs and core for petrophysical analysis. Incorporation of core, log, DST and production data allowed for an understanding of reservoir quality and deliverability. Utilizing a petrophysical analysis, a number of porosity cut offs were defined from 1-30%. Mapping the porosity cut offs allowed for calculation of brine volume across the Company’s mineral leases. Although a 3% porosity is a common cut off used, the data suggests a 6% porosity cut off is more appropriate when considering long-term brine production (see Table 1 below).
