In the stock head video yes it is out now...paul said at the 42 seconds to reinject the waste to another aquifer.I'm going deeper into that statement.
* So the used brine with a few natural minerals only get rejected into a higher zone above the lithium-rich brine, hence no dilution issues with lowering the lithium ppm*
Once the plix is loaded with lithium, it is stripped with a weak hydrochloric acid
which exchanges the lithium from the plix and hydrogen from the hydrochloric acid. The plix is then able to
be recycled and re-enters the brine stream for another cycle. The output of the process is a lithium chloride
which is able to be further processed into lithium carbonate or a lithium hydroxide product.

I would like to know, if anyone at Arizona Lithium could answer this for me;
With the hydrochloric acid how weak is the solution, and has much do you need to produce 1 tonne lithium Carbonate/
How many cycles does the solution last, and the cost of where to put used acid once its depleted, obviously it can't be reinjected to the aquifer as EPA /and environmental permits would knock back the idea for contamination reasons .
As a pior investor in LKE/ their SP tanks because of hidden facts/ not releasing numbers on voloumes/ dates moved 3 years down the track / no releases power issues no connections for 400 miles...etc...\
As a shareholder with many others here with their hard-earned. Aka ex Farmer here..
Honest facts in building trust is the best business and future support from shareholders and investors.
Without this common ethics..many Corps go bust .
To Paul .
I will send you a copy of my request by email and I will put the reply up here in HC for all the shareholders to see.
In saying that, I trust you to be an honest CEO..and hopefully, clarify these issues with your researchers..
Kind Regards
Farmermick..they call me Bennie on here..lol

PROJECT HISTORY
Oil has been explored for and produced in the region for several decades and it remains an oil producing
region to this day. Oil is generally hosted in later geological formations several hundred metres above the
Duperow formation. Academic research into some of the deeper wells in the area led to the lithium
potential of the Duperow formation being identified. It was on this basis that Prairie Lithium was founded by
current director and geologist Zach Maurer and commenced acquiring sub surface rights in the area in
2019.
MINERAL RESOURCE ESTIMATE
Prairie has a JORC mineral resource of 5.7mt of LCE. The resource is based in 279 wells to determine
porosity and 17 wells to determine lithium concentration. The wells include a combination of historical
wells and newly developed wells. The brine resource is considered hydraulically continuous and extends
beyond the AZL resource area.

Category Brine (billion m3) Grade (mg/l) LCE (mt)
Indicated 3.1 102 1.7
Inferred 7.2 106 4.0
Total 10.3 104 5.7

The grade may appear low when compared to South American brine projects which can be up to 1,000
mg/l. Brine resources contain significantly lower lithium concentrations than hard rock projects, and factors
such as size, flow rates, lithium extraction techniques and recoveries can have larger implications on a
projects economic viability than simply the grade.
PROCESSING
Located in Canada, lithium extraction via evaporation of the brine will not be plausible. Direct Lithium
Extraction (DLE) has been developed specifically for this project which has successfully extracted lithium
from the prairie brines in bench scale and pilot plant conditions.
The DLE in this instance involves an ion exchange process where a proprietary ion exchange material
(referred to as a Plix – Prairie Lithium-Ion eXchange) is used to selectively remove the lithium from the
brine. Brine is first pumped to the surface and the plix is added to the brine. The lithium ions of the brine
exchange with the hydrogen ions of the plix.
The waste brine is then re-injected back into the ground, but in
a separate and higher formation than the Duperow. The plix rejects any impurities that may be present
including Mg, K and Na. Once the plix is loaded with lithium, it is stripped with a weak hydrochloric acid
which exchanges the lithium from the plix and hydrogen from the hydrochloric acid. The plix is then able to
be recycled and re-enters the brine stream for another cycle. The output of the process is a lithium chloride
which is able to be further processed into lithium carbonate or a lithium hydroxide product.
The pilot plant has treated in excess of 400m3
of brines during pilot testing and is under continuous
refinement as the project advances.
Testwork continues to be explored for the Prairie brines, with several other DLE technologies including
adsorption being investigated for potential use. We are of the view adsorption may be well suited to these
lower grade brines, however further testing and pilot runs will optimise the flowsheet and the DLE method
proposed.
The project is well serviced by existing infrastructure given it is located in the middle of an operational oil
field. The project will have access to grid power, a local residential workforce skilled in the operation of well
operations, rail, roads and a supportive local Government.
DLE IN OIL FORMATIONS
Global oil giant Exxon has entered the DLE lithium space with a >$100m acquisition of tenure in the
Smackover formation, Arkansas. The Smackover is a well understood oil producing region with known
lithium occurrences in brine layers within the formation. We would expect given the synergies with existing
oil producing projects, the trend for oil majors to explore acquisition opportunities will only increase, and
Prairie could prove to be an attractive option.
