Lithium Chile Announces 300 Mg/L Lithium ON New Arizaro Exploration Well, Commencement of Pre-Feasibility Study and Operational Update

Mine Development & Operations

LITHIUM CHILE ANNOUNCES 300 MG/L LITHIUM ON NEW ARIZARO

EXPLORATION WELL, COMMENCEMENT OF PRE-FEASIBILITY STUDY AND

OPERATIONAL UPDATE

TSX Venture Exchange: LITH For Immediate Release

OTC-QB: LTMCF

CALGARY, ALBERTA, October 17, 2023 – Lithium Chile Inc. (“Lithium Chile” or the “Company”) is pleased

to provide an update on its operations in Argentina and Chile.

HIGHLIGHTS

• Two diamond drill holes completed at the Arizaro Project (the “Project”), Argentina.

o Both holes encountered brine rich formations in areas not previously drilled.

o Results from drilling provide for significant resource upside on the Project.

• Prefeasibility Study on the Project to be completed in April 2024.

• Three diamond drill holes completed on the Molle Verde Project, Chile.

o All three holes encountered brine with two holes displaying good porosity.

ARGENTINA OPERATIONS - ARIZARO PROJECT:

1) ARDDH-02-8 has been drilled to 538 metres with a very brine-rich, sandy formation encountered

at 487 metres. Onsite sampling with the field Turbospec analyzer on six samples collected over 51

metres, returned lithium grades between 297 mg/l and 319 mg/l. Samples sent to the laboratory

reported the following grades:

• 505-metres to 506.5-metres 282 mg/l Li

• 524.7-metres to 526.2-metres 300 mg/l Li

• More sample results from the lower section of the well are pending

The results from ARDHH-02-8 represent a significant exploration upside for the northern part of

the Project, see Figure 1 , where the Company currently do es not have any Mineral Resource

Estimate.

2) ARDDH-03-7 has been drilled to 600 metres. A 120-metre brine bearing formation of sands and

gravels was encountered from 480 metres to end of hole at 600 metres . Prior to testing, a clay

band at 170-metres swelled, restricting access of the sampling and logging tools intended to test

the brine formation for lit hium grades. The hole will be re -entered, opening the clay bottle neck

to allow for casing to be installed, followed by sampling.

3) This week a newly contracted rotary rig will begin drilling two additional water production wells

on the Company’s 100% owned, Chascha Sur freshwater concession where Lithium Chiles first

water well was drilled. The intention of these two additional water wells is to collect the necessary

data to apply for further water usage permits and secure water production for the Company’s

proposed Direct Lithium Extraction (“DLE”) production facility.

4) After completion of the two water production wells , the rig will move back to the main Arizaro

property and drill two new production well s, AR-04 and AR -05. The wells are being drilled to

provide additional data for the Pre-feasibility Study (PFS) as well as to provide future production

wells on the salar.

5) The two additional production w ells, along with three new diamond drill holes will provide the

supplementary data analysis required to better understand the reason behind the significantly

improved lithium grades from the resampling program recently announced (Press Release July 10,

2023). Once drilled, data and test results from AR -04, AR-05 and three additional diamond drill

holes will be used by Montgomery and Associates to interpret the impact of these improved

grades on the overall resource calculation of Arizaro. The 43-101 resource update is expected by

late November.

6) Ausenco Engineering was contracted in early September and has commenced work on the

Company’s Pre-feasibility Study (“PFS”) further advancing the economics and engineering on the

Arizaro project. It is anticipated that the PFS will be completed by April 2024.

7) Lithium Chile’s wholly owned Argentinian subsidiary, Argentum Lithium, has been shortlisted on

Block 4, one of five properties on the northern section of the Salar de Arizaro, released for bid by

the Salta Provincial Mining Corporation, REMSA. It is anticipated the final winners of the bids for

the REMSA properties will be announced after the Argentina Federal election on October 22nd ,

2023.

CHILE OPERATIONS:

1) Drilling at Molle Verde (Llamara) has just finished with the completion of the third hole. The rig is

now moving to the last pad to drill the fourth hole. The first three wells encountered brine, with

holes one and three exhibiting exceptional porosity, with hole 3 flowing brine up the drill pipe

naturally.

2) Sampling is underway and once completed, samples from all exploration holes will be batched

and sent together for assay. Results will be announced when received.

3) While sampling is being completed at Molle Verde, Lithium Chile will commence exploration

work at its Aguilar property. This work will include sampling grid and TEM geophysics to define

the position of three exploratory holes. Drilling on Aguilar to commence before year end.

4) Interest continues to build amongst the major mining companies in Chile’s lithium potential. The

National Lithium Strategy introduced by the Chilean Government earlier this year has stimulated

new interest in Chilean partnerships. Lithium Chile continues to explore various opportunities

and potential joint ventures.

Steve Cochrane, President & CEO comments, “We are very pleased with the speed of the advancement of

our Arizaro project to the pre-feasibility stage. The results from the two new diamond drill holes drilled in

previously unexplored areas of our Arizaro property point to the potentiality of a significantly larger

resource. We are also extremely encouraged with the increased interest seen recently in our Chilean

properties by major mining companies. The latest proposed changes to the lithium mining regulations in

Chile provide a stable regulatory environment and are encouraging new investment.”

The Company is also pleased to announce that it intends to extend the expiry date of an aggregate of

6,922,817 outstanding common share purchase warrants ("Warrants") issued by the Company as part of

a unit of the Company in connection with a non -brokered private placement announced on October 25,

2021, and further amended on October 26, 2021, and October 29, 2021. The Company proposes to extend

the expiry date of the Warrants to June 30, 2024 (the "Extension").

The Extension is subject to approval by the TSX Venture Exchange (the "TSXV"). The Company intends to

issue an updated news release upon receipt, if any, of the Warrant Extension Approval.
