Nevada Lithium Resources Inc. (CSE: NVLH; OTCQB: NVLHF; FSE: 87K)
(“Nevada Lithium” or the “Company”) is pleased to provide a
technical update on its 2024 metallurgical program at its 100%
owned Bonnie Claire Lithium project (the “Project” or “Bonnie
Claire”), located in Nye County, Nevada.
Nevada Lithium’s CEO, Stephen
Rentschler, comments:
“The
high-grade Lithium and Boron mineralization we have identified over
the last two drilling programs presents additional opportunities
that were undiscovered when the Company’s Preliminary Economic
Assessment (“PEA”) was completed three years ago. With Bonnie
Claire now looking to be an analog to Ioneer Ltd.’s Rhyolite Ridge
deposit (“Rhyolite Ridge”), the logical next step was to explore
relationships with companies instrumental in the development of
Rhyolite Ridge.
We are happy
to report that we have engaged Fluor Enterprises, Inc. (“Fluor”) to
develop the metallurgical processes and plant design that will be
incorporated into an updated PEA”, he
continued. “The updated PEA will, for the first
time, reflect the impact of the tremendous grades and intercepts of
Lithium and Boron that we have encountered in the lower high-grade
Lithium and Boron mineralized zone at Bonnie Claire.
Fluor is an
internationally recognized firm with comprehensive capabilities
that have been utilized in some of the world’s largest and most
significant Lithium projects, such as Ioneer’s Rhyolite Ridge,
Albemarle Corporation’s Meishan Project, Jindalee Lithium Ltd. and
Aurora Lithium SA, among others. We think that Fluor’s
participation in our Project clearly reflects the increasing
industry recognition of Bonnie Claire’s position among the world’s
top tier of Lithium and Boron projects.”
Highlights:
- Acid leaching has become the preferred option for treating
material with high Lithium and Boron content at Bonnie Claire.
Preliminary acid leach test work gives 97% overall Lithium recovery
and 98% overall Boron recovery. To date, acid leaching has been
advanced as the typical recovery process for Lithium-bearing Nevada
claystone projects.
- A conceptual two-stage acid leach flowsheet proposes a Boron
stream to produce boric acid and a Lithium stream for generating
lithium carbonate.
- Thermal treatment may be an option for processing high grade
Lithium material with low Boron content at Bonnie Claire.
Processing claystone material with 1,000 ppm Lithium and 1%
searlesite achieved 80% Lithium recovery.
- Fluor Enterprises, Inc. of Greenville, South Carolina and
Kemetco Research Inc. of Richmond, BC (“Kemetco”) will oversee
future test work and develop a process plant design for the updated
Preliminary Economic Assessment.
- Test work should conclude in early 2025, with PEA completion at
the end of Q1 2025.
Previous Work
The 2021 Preliminary Economic Assessment for
Bonnie Claire favored thermal treatment of mineralized material.
This treatment included calcination of material with the addition
of sodium sulfate, followed by hot water leaching. This thermal
treatment achieved high Lithium recoveries of up to 80%. Additional
work by Hazen Research Inc. (“Hazen”) included the successful
production of battery-grade lithium carbonate (see the Company’s
news release dated February 27, 2023). The thermal process on a
bulk (300 kg) sample confirmed the process using the same flowsheet
but achieved a lower 61% Lithium recovery rate. This sample
contained about 11% searlesite. The lower recovery was likely due
to agglomeration by the presence of searlesite.
Newly Identified Boron
The Company has identified a thick zone of
gently dipping, high-grade mineralization at depth. This zone
exhibits both high-grade Lithium mineralization, including 3076 ppm
Lithium over 1100 ft (November 20, 2023 news release) and
high-grade Boron mineralization, including 15,001 ppm Boron over
560 feet (May 22, 2024 news release).
Boron mineralization is contained in the mineral
searlesite, which makes up to 38% of mineralized rock in the lower
zone. Hazen has demonstrated that a high searlesite content reduces
the melting temperature of the material, inhibiting effective
calcination. While the Company has concluded that calcination is
not preferred for the high-grade material at Bonnie Claire, it may
still be an option for material with lower searlesite content, such
as the lower-grade upper zone.
Two-Stage Acid Leaching
To formulate a suitable recovery method for
high-grade Lithium and Boron material at Bonnie Claire, the Company
asked Hazen to conduct preliminary acid leach benchwork and to
develop a conceptual acid treatment process to recover both Lithium
and Boron. To date, acid leaching has been advanced as the typical
recovery process for Lithium-bearing Nevada claystone projects.
Fluor has also advanced the use of acid leach in the Definitive
Feasibility Study for Rhyolite Ridge, the only other known
Lithium-Boron claystone deposit in Nevada.
Hazen has developed a conceptual two-stage
leaching approach using:
- An initial dilute acid leach at 160 kg acid/t solid, to
facilitate the recovery of Boron
- A second concentrated 500 kg acid/t solid for the recovery of
Lithium
Using this two-stage leaching approach, Hazen achieved a 97%
overall Lithium recovery, together with a 98% overall Boron
recovery.
The two-stage leaching approach produces two filtrates: a high
Boron stream to produce boric acid and a high Lithium stream for
generating lithium carbonate. However, there may not be a benefit
to a two-stage leach if Boron content is low. A single stage leach
has the advantage of requiring less solid/liquid separation stages.
The decision to use countercurrent leaching for better acid
utilization will be determined after further test work is
performed.
Fluor and Kemetco
Following the successful preliminary acid leach benchwork and
conceptual flowsheet by Hazen, Nevada Lithium has accepted a
proposal from Fluor and Kemetco. The companies will oversee and
perform future benchwork and develop a process plant for inclusion
into an updated PEA.
Fluor’s Lithium Center of Excellence will set-up and coordinate
a test work program to take place at Kemetco’s lab facility. The
key focus will be to prove the make-up of a conceptual acid-leach
circuit. Fluor and Kemetco’s joint expertise in developing test
work programs for Lithium compounds of similar metallurgy will play
an instrumental role in bringing a high level of certainty to the
Project flowsheet.
It is estimated that the test work program will conclude in
early 2025. The development of a process plant will then feed the
preparation of the updated PEA report pertaining to metallurgy,
capital, and operating expenses (CAPEX and OPEX, respectively).
Global Resource Engineering will prepare an updated PEA, with an
estimated completion date by the end of Q1 2025.

Issue date of February 25, 2022) (the “PEA” or the

Economic Assessment represent forward-looking information. This
economic assessment is, by definition, preliminary in nature and
includes inferred mineral resources that are considered too
speculative to have the economic considerations applied to them
that would enable them to be categorized as mineral reserves. There
is no certainty that the Preliminary Economic Assessment will be
realized. Mineral resources are not mineral reserves as they do not
have demonstrated economic viability. There is no certainty that
all or any part of the Mineral Resources will be converted into
Mineral Reserves.
