Lithium Chile Increases Resource BY 81% - Bringing Total Indicated Resource to 1,337,000 and Inferred Resource to 1,250,000 Metric Tonnes of Lithium Carbonate Equivalent. Lithium Chile Also Awarded “Lithium Company of the Year” at 2022

Resource Estimates

LITHIUM CHILE INCREASES RESOURCE BY 81% - BRINGING TOTAL INDICATED

RESOURCE TO 1,337,000 AND INFERRED RESOURCE TO 1,250,000 METRIC

TONNES OF LITHIUM CARBONATE EQUIVALENT.

LITHIUM CHILE ALSO AWARDED “LITHIUM COMPANY OF THE YEAR” AT 2022

MINES AND MONEY LONDON CONFERENCE.

TSX Venture Exchange: LITH For Immediate Release

OTC-QB: LTMCF

CALGARY, ALBERTA, December 5, 2022 – Lithium Chile Inc. (“Lithium Chile”) is pleased to announce the

results of an updated resource report at the Salar de Arizaro. The update resulted in a significant

increase to Lithium Chile’s lithium carbonate equivalent resource. The increase is a result of the success

of its second production well. That second well, drilled 3.6 kilometers away from the initial production

test well, encountered significantly increased thickness in the brine reservoir between 343 meters and

598 meters of depth.

HIGHLIGHTS:

 Total Indicated and Inferred resource from second well of 1,167,000 metric tonnes of lithium

carbonate equivalent.

 Total Indicated resource from the first two wells is 1,337,000 metric tonnes and Inferred

resource is 1,250,000 metric tonnes for a total of 2,587,000 metric tonnes of lithium carbonate

equivalent an 81% increase over the first well.

 The third production test well is expected to start drilling within a week.

The updated resource estimate was prepared by Montgomery and Associates, an independent

engineering firm that has supervised the drilling program such that all parameters necessary to meet the

requirements of NI 43-101 are fulfilled.

CONTINUED DRILLING

Lithium Chile is proceeding with a production test well program that involves a total of 4 production test

wells. Drilling of the third production test well slated to begin within the next week. It is noteworthy

that Lithium Chile has designed the drilling program to include four production test wells in total. While

each individual test well has a radius of investigation for resource estimate calculations, it is intended

that upon completion of the fourth production test well, if successful, the area between the wells will

thereafter be included in resource estimate calculations - all in accordance with the requirements of NI

43-101.

Steve Cochrane, President, and CEO commented, “This is a significant resource increase as a result of

just one additional well - almost doubling the size of the initial resource. This success gives us great

confidence in the areal extend of the Salar de Arizaro – one of the largest in Argentina. What is

important to note is that should our next two test wells be successful in establishing a continuation of

the brine reservoir, the resources attributable to Lithium Chile may be even more significantly increased

as a result of filling in the area between the test wells. We look forward to reporting the results of the

third production well in the near future - and those of the fourth test well thereafter”.

WATER WELL:

Lithium Chile is also pleased to announce the completion of a successful fresh water well on the

southern flank of the Salar de Arizaro. In June 2022, Lithium Chile identified a potential freshwater

aquifer and drilled the target during July and August. A 100-meter-thick freshwater aquifer was

encountered and during September, the well was completed, and equipment was installed to determine

the productivity of the well. Based on data collected over September and October, a water usage

application was submitted to the Salta Environmental Ministry for a permit allowing Lithium Chile to use

up to 75 cubic meters of fresh water per hour. This production rate is more then sufficient to support

Lithium Chile’s plans for a 15,000 tonne a year production facility - using either DLE or evaporation

production methods.

AWARD:

Lithium Chile is honoured to announce it was awarded “Lithium Company of the Year” at the 2022,

Mines and Money, International Event in London.

Michelle DeCecco, Vice President & CCO comments, “This award belongs to the entire Lithium Chile

team. 2022 has been a transformational year for the Company; that has been a result of the dedication

and talents shown by our incredible group across the globe. Being recognized as “Lithium Company of

the Year” is foretelling to the exciting plans, and goals we have for 2023”.
