The firm revealed that partner Genesis Water Technologies Inc (GWT) was seeing promising results from its larger second phase bench testing to recover lithium.
High recovery numbers..
The feedstock used in the tests comes from the group's Clayton valley project in Nevada and has already shown remarkably high lithium recovery numbers in initial tests, the group pointed out.
More than 95% of the lithium contained was taken into solution using weak acid solution and up to 75% using only deionized water.
One of the key points from early sample results using just deionized water was that both magnesium and iron were left behind.
This created a high lithium brine of 596 parts per million (ppm) with a very low magnesium content of 22 ppm and iron content of 16 ppm.
Notably, most producing lithium brines have ratios of 1.6 to 6 parts magnesium to lithium, so this lithium content ratio is high - at 27 ppm of lithium to every 1 ppm of magnesium.
Next month (November), GWT will start initial testing of leach samples to determine yield into leach solutions.
''Genesis Water Technologies looks forward to promising results from this phase of testing analysis and anticipates that achievement of the goal of obtaining battery-grade lithium with high recovery yield will prove economically viable," said Nick Nicholas of GWT.
"At Genesis Water Technologies, we utilize innovation in water. We are excited to partner with Enertopia to become leaders in the lithium evolution."
Enertopia said it was looking forward to the results from the continuing testing program being done by GWT.
One of the main features using modern technology is that Enertopia would not require pumping of any groundwater from Clayton Valley.
A lithium hotspot
In August, the firm said it had acquired claims in the lithium hotspot - Clayton Valley, Nevada.
Significantly, work there had shown the high solubility of the contained lithium, meaning it should be possible to create a brine suitable for extracting lithium using GWT' patent pending extraction technology.
"The company is extremely pleased with this project as it exceeds all the internal parameters that the company had set out to achieve (high lithium values at surface, excellent road and access to power)," president of Enertopia, Robert McAllister, told investors.
But why lithium...?
The price of lithium has risen 18% this year compared to 2016, and more than doubled since 2013, and there are reportedly more rises to come.
Once known perhaps only as a treatment for psychiatric disorders, the white metal is becoming increasingly known around the globe for its use in lithium-ion batteries, used in everyday objects such as mobile phones.
But the real driver (pardon the pun) is electric vehicles (EVs) and cars. A vital component in these vehicles are powerful batteries, made from, among other things, lithium.
The massive increase in demand for electric vehicles is creating a significant potential for a shortfall in the commodity in the very near future, reckon experts, and similarly raising the profile and outlook for many lithium focused companies.
