E3 Lithium Discovers Lithium Concentrations as high as 87 mg/L in the Nisku Aquifer


  • E3 Lithium sampled the Nisku Aquifer in six locations in its Clearwater Project Area, resulting in lithium concentrations as high as 87 mg/L
  • The Nisku Aquifer is above the Leduc Aquifer and is laterally continuous throughout E3 Lithium’s permit area in south-central Alberta; E3 Lithium owns the mineral rights to both aquifers
  • The Nisku Aquifer has similar geologic properties to the Leduc Aquifer including historic high flow rates, which may support the production of additional commercial quantities of lithium

CALGARY, ALBERTA, January 25, 2024 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3 Lithium” or the “Company”, Alberta’s leading lithium developer and extraction technology innovator, today announced the discovery of higher lithium concentrations in the Nisku Aquifer (the Nisku) through a new six well sampling program conducted late in 2023.

E3 Lithium sampled brine in the Nisku from six well locations in its Clearwater Project Area that outlined lithium concentrations as high as 87 mg/L. These results are from the first Nisku samples in the Clearwater Project area, and are higher than the historic Nisku samples, which outlined lithium grades up to 75 mg/L.

Table 1: Lithium Concentrations Sampled from Six Wells in the Nisku

Well number Lithium grade
6-11 81 mg/L
16-35 87 mg/L
6-25 87 mg/L
9-23 65 mg/L*
13-24 83 mg/L
16-26 84 mg/L

* This sample produced lower lithium concentrations with brine chemistry that differed from the other wells and historic water analysis data from the same well, which may indicate contamination. E3 Lithium is investigating potential causes further and may resample.

“Finding higher concentrations of lithium in the Nisku is a significant discovery,” said Chris Doornbos, President and CEO of E3 Lithium. “This opens the door to potentially produce from an additional aquifer to the Leduc in the future. The Nisku is well known in Alberta as a prolific oil producer and is similar to the Leduc in that respect. E3 Lithium has not completed a resource estimate in the Nisku, and if successful, would add additional resources to our already significant resource base from the Leduc.”

The previously reported lithium concentrations ranging from 37 mg/L to 75 mg/L were from different well locations and were collected from oil and gas wells between 2017 and 2020.

The Nisku brine samples were analyzed by a third-party certified laboratory, following independently verified sample acquisition procedures that maintained a strict chain of custody, in accordance with The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) guidelines.

About the Nisku

The Nisku is located above the Leduc Aquifer and stretches across E3 Lithium’s entire permit area where the Company holds mineral rights, which include the rights to the lithium within the Nisku. The Nisku and Leduc are Devonian stacked reef complexes that have similar geological properties, however, the Nisku is generally not as thick as the Leduc. Both aquifers have high porosity and permeability, which allows for high volume deliverability (i.e. high brine flow rates), that may support the production of commercial quantities of lithium.

The Nisku and Leduc Aquifers are confined aquifers, meaning they are not connected to the surface or any shallow, fresh, groundwater sources. The fluids in the aquifers are contained under pressure which naturally assists with fluid production. The Leduc and Nisku Aquifers in E3 Lithium’s project area occur between 2-3 km below the earth's surface, depending on the location. It is common for historic oil and gas production to ‘co-mingle,’ which allows for the simultaneous production of the two reservoirs for hydrocarbons, and a similar scenario could be applicable to the production of lithium.
