CleanTech Lithium PLC (” CleanTech Lithium” or “CTL” or the “Business”) Favorable Pump Test Outcomes Assistance Projects Salt Water Extraction Design Salt Water Reinjection Test to Commence, First in Chile ´ s Lithium Sector
CleanTech Lithium PLC ( OBJECTIVE: CTL, Frankfurt: T2N, OTC: CTLHF), an expedition and advancement business advancing next-generation sustainable lithium tasks in Chile for the EV shift, shares arises from essential hydrogeological deal with pump test programs carried out at Laguna Verde and Francisco Basin. This is followed by a salt water reinjection test to begin at Laguna Verde, a very first for the lithium sector in Chile.
Emphasizes:
· Repaired period pump tests finished at Laguna Verde (wells LV05 and LV06) and at Francisco Basin (FB01).
· Pump tests offer essential information for hydrogeological designs consisting of aquifer transmissivity, which is utilized to design bore field circulation rates for salt water extraction in a business operation.
· Computed transmissivity from the LV05 and LV06 pump tests support the bore field circulation rates of 30L/s that were designed in the Laguna Verde scoping research study revealed in January 2023.
· The FB01 pump test taped a high transmissivity that represents a modelled circulation rate of around 80L/s in a well developed for an operation phase job.
· This high circulation rate will offer a favorable input into the Francisco Basin Scoping Research study which is advancing well.
· The very first of a two-stage salt water reinjection test will begin imminently at Laguna Verde.
· Salt water reinjection into aquifers is a crucial benefit to Direct Lithium Extraction (DLE) operations and CleanTech Lithium is leading the sector in Chile with this test-work.
· An upgrade will be launched quickly on the drill program development at all 3 tasks, consisting of the lab assay results for the 2023 program at Laguna Verde, the last batch of which is anticipated to be gotten next week.
Aldo Boitano, President, of CleanTech Lithium PLC, stated:
” I am happy at the development we are making on our comprehensive work programs throughout our 3 various basins.
” The pump test results at Laguna Verde and specifically at Francisco Basin exceeded expectations and with the start of the first-ever reinjection test in Chile simply round the corner, this might be a game-changing minute for Chile ´ s lithium sector, a significant move on for the Business and the broader lithium market to produce lithium with very little ecological effect; what we describe as ‘green’ lithium.
We will offer another upgrade quickly on our drill program outcomes and development at all 3 of our tasks, which will be followed by upgrading the marketplace on JORC upgrades from Laguna Verde, along with JORC upgrades and the Scoping Research Study for Francisco Basin.”

Favorable Arise From Pump Test Programs
CTL remains in the procedure of developing a hydrogeological design for the operating phase of the tasks that will consist of the modelling of the extraction bore field. Pump tests offer essential information for the hydrogeological design and are essential turning points for brine-based resource tasks.
Laguna Verde:
At Laguna Verde, repaired period pump tests were carried out at LV05 and LV06. The wells are cased with a size of 8 inches which constrains the size of the pump and for that reason the circulation rate utilized in the pump test. At LV05, a circulation rate of 18L/s was utilized and based upon the aquifer action, which is determined by the drawdown in the well and the healing rate taped in the well and piezometers found at 50m and 240m from the well, the aquifer transmissivity is determined. At LV06 the test was performed at a circulation rate of 14L/s. Both wells taped >> 80% healing within thirty minutes and complete healing within 36 hours.
Based upon the circulation rate and aquifer action a transmissivity for LV05 and LV06 was determined as 27.1 m 2 and 22.6 m 2 each day respectively. Based upon the determined transmissivity, the modelled circulation rate for a business bore with a size of 14 inches is anticipated to be around 30L/s. This remains in line with the circulation rate of extraction bores utilized in the finished Scoping Research study for Laguna Verde, revealed in January 2023, supplying essential verification of the tasks ´ bore field extraction capability.

Francisco Basin:
At the Francisco Basin job, a repaired period pump test has actually been finished at FB01, a well cased with a size of 8 inches, with a circulation rate of 19L/s used for the preliminary test. The aquifer drawdown was very little and the healing rate quick, leading to a high transmissivity estimation of 226m 2 each day. Based upon the determined transmissivity of FB01, the modelled circulation rate for a business bore with a size of 14 inches is anticipated to be around 80L/s. The aquifer at Francisco Basin is formed by several sand systems restricted by clay systems, which is geologically analyzed to have a high possible aquifer transmissivity. This is a really favorable outcome, well surpassing expectations, and will feed into the Francisco Basin Scoping Research study that is presently advanced, with a relatively lower variety of bores needed to draw out the necessary volume of feed salt water.

Reinjection Program to Begin – The First Reinjection Test in the Chilean Lithium Sector
For a DLE based job, the other crucial element of the job’s hydrogeological design is the reinjection of invested salt water into the subsurface aquifers of the basin. At Laguna Verde, and at Francisco Basin, the Business has a dominant period position in the basin permitting extraction and reinjection of salt water in various zones of the basin. In the Scoping Research study finished for the Laguna Verde job 2 websites were proposed for reinjection bore fields as displayed in Figure 3. The main basis for website choice is to restrict the range and elevation distinction in between the reinjection website and the DLE procedure plant, where invested salt water will be pumped from, and a beneficial website geology for subsurface sediments that will host the re-injection salt water volume while supplying a geological separation with the resource location.
The Business ´ s main hydrogeology specialist Gestion Ambiental SA (SGA), a worldwide company which runs throughout South America, has actually developed a two-stage salt water reinjection test at Laguna Verde with the very first phase prepared to be carried out in the coming weeks. This will include consistent circulation rate tests at various depths and pressures. Salt water from LV06, which is on the east side of the basin, will be injected into well LV05, on the north-west side of the basin in the relative area of the location of the basin where reinjection is prepared, as displayed in Figure 3. Downhole geophysics have actually been finished at LV05 and the well is anticipated to have a representative geology of the prepared reinjection website.

The 2nd phase includes long-lasting tests, in wells found at the prepared reinjection website, to offer legitimate hydrogeological simulations of the salt water reinjection operation. This information will offer essential information for the hydrogeological design and the job’s ecological effect evaluation, among the essential last regulative approvals needed for a job. To the Business ´ s understanding, this will be the very first salt water reinjection program carried out in the Chilean Lithium sector. Significant lithium manufacturer Albemarle just recently revealed that it would begin its very first reinjection program at Salar de Atacama, the world ´ s biggest lithium production website, at the end of this year. CTL intends to continue to be the leader in establishing a salt water reinjection design, a crucial to an effective DLE based job, in Chile.
