Vancouver, BC  – April 2, 2024 – Lithium South Development Corporation (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ)(the “Company” or “Lithium South”) is pleased to announce the commencement of development activities for pumping well PW23-AS-02, located within the Alba Sabrina tenement. The Alba Sabrina claim is the largest of the five, salar located claim blocks which total 3,287-hectares of the 5,687-hectare Hombre Muerto North Lithium Project (“HMN Lithium Project”) package. Pumping well PW23-AS-02 has been completed to 400 meters of depth and is being prepared for a long-term pumping test.

Initial assessments suggest the well could be highly productive. Emergence, which is brine surging out of the hole, has been observed. This early indication is a promising sign for brine production potential.

The planned installation of a custom-made metal capsule, functioning as a valve to control upwelling, further underscores the anticipation of substantial brine production. Implementing this valve highlights our proactive approach to managing the well’s emergent behavior, indicative of its expected high yield. A 20 HP pump set is to be deployed to a depth of approximately 58 meters, which aligns with the presence of the first filter in order to optimize brine pumpability. As the pumping operation commences, adjustments to pump capacity or depth may be made to maximize brine extraction.

“We are very pleased with our results to date and await further information from this wells performance,” stated Adrian F. C. Hobkirk, Founder, President & CEO.

Upon long-term pump test completion of well PW23-AS-02, a pumping well is planned to be drilled on either the Viamonte or Norma Edith claim blocks south of Alba Sabrina.  Continued development success and our Preliminary Economic Assessment Financial Model, published on March 04, 2024, has brought attention to the Company. Management is reviewing potential industry alliances or other potential business transactions and will apprise the shareholders of any developments.

Summary of Economic Results

Table 1: Lithium South PEA Summary of Economic Results

Project Overview 

Table 2: Lithium South PEA Project Overview

Resource Estimate

The resource estimate for this PEA was prepared in accordance with C.I.M. requirements/definitions and uses best practice methods specific to brine resources, including a reliance on core drilling and sampling methods that yield depth-specific chemistry and effective (drainable) porosity measurements. The technical report filed November 6, 2023, is titled, Updated Mineral Resource Estimate – Hombre Muerto North Project, NI 43-101 Technical Report Catamarca and Salta, Argentina, Mark King, PhD, PGeo, Peter Ehren, M.Sc, MAusIMM, September 5th, 2023.  The report was prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects, on behalf of the Company by independent consultants Groundwater Insight of Halifax, Nova Scotia, Canada.

Operating Costs

Table 3: Lithium South PEA Operating Cost Details

Capital Costs

Table 4: Lithium South Capital Costs Details

Capital costs (CAPEX) have been updated with quotations from current suppliers working in project construction and development in the Puna region of Argentina.  CAPEX estimates include an Indirect Cost of 16.6% of Direct Costs, and a contingency of 30% of Total Costs.

Project Location and Environmental Permitting

The HMN Lithium Project is located at the northern portion of the Salar del Hombre Muerto, at the boundary zone of the Catamarca and Salta provinces, 170 km southeast of the city of Salta.  The project area comprises a collection of properties or concessions acquired under purchase options from the existing owner.  The properties are held as “minas” (full mining licenses not subject to further area reduction requirements) by a wholly owned Argentine subsidiary of the Company.  The HMN Lithium Project comprises six properties distributed over the Salar for a total of 3,237 hectares.  All properties are subject to a mining license for borates.  The area of the property is not subject to any known environmental liabilities.

Lithium Pricing

A lithium price of $US20,000/tonne (t) was assumed for the study, assuming a 2029 production start-up.  The price of lithium has been volatile in recent months, declining from a peak of approximately US$85,000/t in November 2022 and stabilizing to US$13,000/t in 2024.  The selected price was based on current published market analysis and by benchmarking the price assumptions found in multiple technical reports from similar brine lithium projects. The benchmarking exercise provided a long-term price range of between US$20,000 and US$25,000/t, with an average of US$22,400/t over seven projects.

The assumption of US$20,000/t is deemed to be reasonable by the QP, based on the revised documentation.

Processing

The PEA models process eco-system covers the following units:

The brine chemistry is similar to other brines in the region, which allows the brine to be processed using similar processing technology as existing producers.  The nominal extraction rate of the design is 179 liters per second.  After an initial preconcentration, lime is added to the brine, which removes a large part of magnesium as magnesium hydroxide and the sulfate as gypsum.  When the low magnesium and calcium brine is concentrated to about 0.75% it is fed to the lithium carbonate plant.  Most of the noxious impurities that are still left in the brine are removed by selective precipitation through the addition of a solution of soda ash and slaked lime and a final ion exchange polishing.  The impurity free brine is then sent to specially designed carbonation precipitators.  To produce technical-grade lithium carbonate, a soda ash solution is added at high temperatures, leading to the precipitation of solid lithium carbonate.  This solid is then subjected to a series of processes: it is filtered in a centrifuge, washed, repulped, centrifuged once more, and finally washed again.  The lithium carbonate is dried and packaged in maxi bags, to be finally transported to the client.  The main consumption of reagents in the process is shown in a table below.

Table 5: shows the consumption of reagents required to produce technical-grade lithium carbonate.

Increased Lithium Recovery

The report has an updated lithium recovery process for the HMN Lithium Project brine, which uses industry proven evaporation.  An adjustment in the processing sequence will reduce lithium loss as brine entrainments in harvested salts, in the magnesium hydroxide, and in calcium sulfate solids, obtaining a lithium recovery of approximately 70%, an improvement from the previous recovery of 50%. Peter Ehren, M.Sc., MAusIMM, is the QP responsible for Mineral Processing.

Vancouver, BC – March 30, 2023 –  Lithium South Development Corporation  (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt OGPQ) (the “Company”) is pleased to announce the completion of NM01, the final hole of the current resource expansion program at the Hombre Muerto North Lithium Project, Salta Province, Argentina. The hole is located on the Natalia Maria Claim Block, a 115 hectare area strategically located on the salar.  Drilling at NM01 has intersected brine-bearing interbedded sediments and fractured halite from surface to a depth of approximately 200 meters.  Below that, to the final borehole depth of 375 meters, the halite has lower permeability.  Nine packer samples have been collected between 24 and 189 meters, with a density range of 1.215 to 1.218 g/mL and a conductivity range of 196.3 to 209.5 mS/cm.  Samples will be sent to Alex Stewart Laboratories (ISO Certified Mendoza, Argentina) for analysis.

A monitoring well will be installed to test the upper, more permeable, halite.  A separate shallow well will be installed on the same platform to test the shallow interbedded sediments.   The goal of the monitoring wells are to provide a preliminary indication of whether the claim block will support one or more shallow pumping wells for potential future lithium production.

The 2022-2023 resource expansion program is comprised of a total of eight core wells, seven were drilled on the Alba Sabrina Claim Block, the largest in the project package at 2,089 hectares.  Combined with the newly completed hole NM01 at the Natalia Maria Claim Block, and the 2018 drill program at the 383 hectare Tramo Claim, over 75 % of the salar located claims has now been drill tested.

A new updated lithium carbonate equivalent resource will be calculated under the supervision of Groundwater Insight, of Halifax, Nova Scotia, Canada.  Management expects to substantially add to the current 571,000 tonne LCE resource identified at the Tramo Claim Block in 2018 (October 02, 2018 News Release).  The intent of expanding the current resource is to increase the project size potential from the 5,000 tonne per year operation defined in the 2019 Preliminary Economic Assessment (filed August 12, 2019).

Vancouver, BC – December 13, 2022 – Lithium South Development Corporation (the “Company”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ) is pleased to provide results from the ongoing drill campaign at the Hombre Muerto North Lithium Project (HMN Li Project) in Salta Province, Argentina.  The resource expansion drill program is comprised of four core holes (Holes AS01, AS02, AS03 and AS04) located north to south, along a channelized extension off the main salar, and three core holes (Holes AS05, AS06 and AS07) along the west side of the channel (see enclosed drill map).  Two drill rigs are operating on site.

Lithium South Drill Map – revised drill targets for resource expansion.

The western boundary of the salar extension has now been expanded based on current results from Holes AS05 and AS06, which have encountered significant lithium brine (grade and thickness).  Drilling results indicates a wider salar channel than the initial concept.

Hole AS05, located approximately 800 meters west of hole AS03, has been completed to a depth of 260 meters, with a brine zone of approximately 185 meters.  Eight packer samples have been acquired. Assay work is being performed at Alex Stewart Laboratories of Mendoza, Argentina, on samples acquired under the supervision of Dr. Mark King, a Qualified Person under NI 43-101.  The Company is reporting results from three samples received so far from Hole ASO5:

1. Sample HMN 139 located at the top of the hole at 35 meters, and within an alluvial fan with freshwater influence, returned 434 milligrams per liter lithium (mg/L Li).
2. Sample HMN 140 was taken at 52 meters depth and returned 725 mg/l Li.
3. Sample HMN 141 was taken at 66 meters depth and returned 701 mg/l Li.

Hole AS06 located approximately 800 meters west of hole AS02 is encountering similar geology to hole AS05.  The hole is currently at 170 meters and will be continued down to basement.

Hole AS02 located in the center of the salar channel, is now at 240 meters depth.  Borehole logging indicates predominantly medium-grained sand.  To avoid issues with collapse of the sandy materials, sampling will be conducted at the conclusion of the hole.

Site preparation work is underway to locate Hole AS07 at the southwest.

Company President and Chief Executive Officer Adrian F. C. Hobkirk is quoted, “The ongoing exploration is returning consistently excellent results.  Holes located to the west of the claim area are delineating the Alba Sabrina salar channel to be wider than expected, which could positively impact the expansion of the total resource at the Hombre Muerto North Lithium Project.”

Vancouver, BC – August 19, 2022 – Lithium South Development Corporation (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt OGPQ) (the “Company”).  The Company is pleased to provide an update on process test work currently being conducted on a 12,500-liter bulk brine sample from the Hombre Muerto North Lithium Project (HMN Li Project), located in Salta. Argentina.  The purpose of the test work is to validate evaporation as a viable concentration method to produce battery grade lithium carbonate.  The work is performed as part of the preparations for a potential on site pilot-plant aiming to validate the process for the Feasibility Study.  The work is being performed by Eon Minerals a Delaware based company with laboratory facilities in Salta, Argentina.  The work is being supervised by Alex Mezei, P. Eng., a Qualified Person under NI 43-101.

We are pleased to report lithium recoveries of 86% for the pre-concentration evaporation, 80% for liming and 97% for concentration evaporation.  The cumulative lithium recovery after these front-end stages was 67%.

A sample of the resulting concentrated brine was subjected to preliminary laboratory testing by solvent extraction (SX).  The results produced a raffinate containing about 12 mg/L at nearly 99% boron removal efficiency.  The key chemical analyses were confirmed by duplicates performed at Alex Stewart and SGS laboratories, both ISO Certified and located  in Argentina.

Based on these results, the bulk SX stage was initiated on 210 L of concentrated brine sample containing 14.4 g/L Li (1.25% wt. Li)

The sample produced by the current SX work will be further subjected to advanced test work aiming to produce a battery grade lithium carbonate sample.  The interim stage involves a carbonation, bicarbonation and ion exchange.

Based on the metallurgical response of the sample during the pre-concentration, liming, concentration and SX stages, the results to date are indicative of a realistic possibility for achieving the purity requirements for the battery-grade lithium carbonate.

Company Director and Chief Operating Officer, Fernando Villarroel states, “We are very pleased with these results which demonstrate our team has the expertise to produce a clean brine ready to produce Lithium Carbonate battery grade.”

Lithium South’s resource expansion drill program is underway at the Alba Sabrina claim block on the world-renowned Hombre Muerto Salar.  A second drill rig is being added to move the drill program forward and potentially expand the current Lithium Carbonate Resource.  View the active drilling on our live stream at www.lithiumsouth.com/live-cam.

HIGHLIGHTS

1. Five double packer samples obtained from first hole AS01
2. Lithium values range from 732 mg/l lithium to 772 mg/l lithium
3. Lithium magnesium ratio remains favorable at under 4 to 1
4. Drilling will continue to basement rock

Vancouver, BC – August 10, 2022 – Lithium South Development Corporation  (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ) (the “Company”)is pleased to provide an update on the drilling campaign currently underway at the Hombre Muerto North Lithium Project (HMN Li Project) Salta Province, Argentina.

First hole AS101 began to turn on June 12, 2022.  The hole is located in the middle of the Alba Sabrina Claim Block which, at 2,089 hectares, is the largest in the project package.  The drilling method is diamond drill hole with double packer sampling at select intervals.  Hole AS-01 has now been drilled to a depth of 262 meters, with the intention of drilling to the basement rock.

High grade lithium values have been confirmed in five samples taken by double packer at select locations within the drill string completed to date.  The program is supervised by Dr. Mark King, a Qualified Person under National Instrument 43-101, and Principal Hydrogeologist and President of Groundwater Insight, Inc.  Dr. King has an extensive background in lithium brine resource and reserve estimation.

Of further note is that the lithium to magnesium ratio remains in a very favorable range of under 4 to 1.  Samples were assayed at Alex Stewart Laboratories of Mendoza, Argentina, an ISO Certified laboratory.

Table 1. Drill Samples of Hole AS-01

Hole AS-01 geology as observed is a mixture of sand and clay for the first 49.6 meters, followed by a fractured basaltic zone from 49.6 meters to 159.25.  The basaltic zone is underlain by a cavern, to 164.5 meters.  At 164.5 meters to 200 meters a sand zone was penetrated, followed by a clay/sand/ortho quartzite zone down to the current depth of 262 meters. Drilling fluid behavior over most of the drilled interval indicates favorable permeability and porosity. Interestingly, the basalt encountered at depth in the borehole is considered to correlate with surface basalt adjacent to the salar, indicative of an up-lifted block next to the salar.  The 2,000-meter drill program is expected to continue for the next several months. Results will be reported as they are obtained.

Resource Drill Expansion Program

The objective of the program is to potentially expand the current Lithium Carbonate Resource which is defined with an average grade of 756 mg/L    lithium within 571,000 tons in the Measured and Indicated Categories (See news release December 4, 2018, and NI 43-101 compliant Technical Report titled, Initial Measured and Indicated Lithium and Potassium Resource Estimate, Hombre Muerto North Project, Salta and Catamarca Provinces, Argentina, prepared by independent consultants Montgomery and Associates of Santiago, Chile).

The current Resource is contained solely on the Tramo Claim Block, which is 383 hectares in size.  Tramo is one of five Salar-located, non-contiguous claim blocks that comprise the total project area of 3,287 hectares.  The drilling program will focus on exploration on the Alba Sabrina Claim Block, which is 2,089 hectares in size.

A recent TEM Study at the Alba Sabrina Claim Block (See October 4, 2021, press release) provides potential indication of a surficial halite aquifer of approximately 75 meters of depth, with potential indication of a clastic brine aquifer immediately below.  The TEM Study was limited to a depth of approximately 350 meters, with the basement rock not confirmed.  The drill program will attempt to drill to basement, limited to approximately 700 meters by the depth potential of the drill rig.

Company Director and Chief Operating Officer, Fernando Villarroel states, “We are very pleased to encounter high lithium values in our first hole at the Alba Sabrina Claim Block.  We look forward to continued drilling and to fulfilling our corporate milestone of substantially increasing the lithium resource at the project.”

Vancouver, BC – April 27, 2021 – Lithium South Development Corporation (the “Company”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt OGPQ) is pleased announce it is moving ahead with plans to potentially expand the current lithium resource at the Hombre Muerto North Lithium Project (HMN Li Project), located in Salta Province, Argentina.

The 3,287-hectare project is comprised of five separate areas located in the northern portion of the salar. The current resource of 571,000 tonnes of lithium carbonate equivalent is located on the 383-hectare Tramo Claim.  The resource was detailed in a National Instrument 43-101 compliant report filed December 4^th, 2018 titled, Initial Measured Lithium and Potassium Resource Estimate Hombre Muerto North Project, Salta and Catamarca Provinces, Argentina, authored by independent consultants Montgomery and Associates, is summarized below:

Table 1. Hombre Muerto North Lithium Brine Resource Statement

Tonnages are rounded off to the nearest 1,000. Cutoff grade: 500 mg/L lithium, but no laboratory results were less than the cutoff grade. The conversion used to calculate the equivalents from their metal ions is based on the molar weight for the elements added to generate the equivalent. The equations are Li x 5.3228 = lithium carbonate equivalent and K x 1.907 = potassium chloride equivalent. The reader is cautioned that mineral resources are not mineral reserves and do not have demonstrated economic viability.

After technical review, management believes the current identified resource has excellent potential to be expanded.  To accomplish this, the Gaston Enrique, Natalia Maria and Alba Sabrina claims will be sited for drill programs.  The Company has located a service provider who has a drill rig located on the salar near the Alba Sabrina claim block and is negotiating a drill contract.  The Gaston Enrique claim block is located on the Catamarca side of the Hombre Muerto salar, and is the oldest claim located within the dual jurisdiction area. Management believes an Environmental Impact Report and drill permits can be obtained for this project area, which is located approximately 100 meters north of a drill hole recently completed by POSCO.  A recent corporate video of the HMN Li Project can be viewed at the Company website at www.lithiumsouth.com.

The project area under purchase option to the Company is situated contiguous to significant lithium development. Korean giant POSCO are moving ahead with plans to construct a 25,000 tonne per year conventional lithium extraction operation contiguous to the Company area. The recently announced 4-billion-dollar merger between Galaxy Resources and Orocobre will likely see further development of the Galaxy owned portion further to the south.

Highlights:

• 80% recovery of lithium from brine using Chemphys XFP-Lithium Direct Lithium Extraction (DLE) process.
• Near doubling of lithium recovery rates from conventional evaporation extraction
• Bulk brine sample acquisition for pilot scale test work.

Vancouver, British Columbia / March 17th, 2021 – Lithium South Development Corporation  (TSX-V: LIS) (OTCQB: NRGMF) (Frankfurt OGPQ) (the “Company”) is pleased to report completion of laboratory scale evaluation using synthetic brine modeled on the Hombre Muerto North Lithium Project (HMN Li Project) chemical composition. The test work was completed by Chengdu Chemphys Chemical Industry Ltd. (Chemphys) utilizing its proprietary XFP-Lithium Direct Lithium Extraction process, which selectively extracts lithium ions from brine. Testing was performed at the Chemphys ISO certified facility in Chengdu, China. Independent check sampling was completed at the PONY Testing International Group Co Ltd., an ISO/IEC 17020 and ISO/IEC 17025 certified laboratory. All work was completed under the supervision of Don Hains of Hains Technology Associates of Toronto, Canada, who is acting as the Qualified Person.

The process conditions were screened to select optimized parameters, (including operating at 25 ^oC). The average lithium recovery achieved was 80%, producing an intermediate lithium sulfate product enriched from 0.7 g/L Li to 1.7g/L Li. This represents a near 100% increase in lithium extraction, in comparison to the conventional evaporation process results completed by the Company. The laboratory test work shows good selectivity of the adsorption process, high Li adsorption, elution and total recovery rate and low adsorbent loss rate. Chemphys also determined that the intermediate lithium sulfate produced met the feedstock quality requirements to directly produce battery grade lithium carbonate.

Conventional lithium extraction involves the construction of large evaporation ponds to concentrate the lithium contained in the raw brine. The costs of pond construction is significant, the environmental footprint is large, and the production lead time is approximately 18 months. These factors contribute to the challenges of applying the traditional evaporation process to meet increasing market demand. The Chemphys process is part of an innovative class of lithium extraction technologies, Direct Lithium Extraction ( “ DLE “ ). The XFP-Lithium process allows for faster and more efficient extraction of lithium from brine with significantly reduced evaporation pond footprint. The Company is evaluating both conventional evaporation and DLE to determine the optimal process method for the HMN Li Project.

The next phase of test work will involve pilot plant cycle testing using synthetic brine and validation using a large bulk sample of HMN Li Project brine. The bulk brine sample acquisition will be conducted next week, with the sample expected in China by March.  The pilot program will further validate the process conditions established by the laboratory test work on a larger scale, continuous cycle program, and also produce high quality lithium carbonate samples. The pilot testing is expected to be completed in 2Q 2021.
