CALGARY, ALBERTA – TheNewswire – November 3, 2022 – Lithium Chile Inc. (“Lithium Chile” or the “Company”) (TSX:LITH) (OTC:LTMCF) is pleased to provide an operational update on its Phase Two development program at Salar de Arizaro (“Arizaro”) in Argentina. The Company reports the completion of its second production well, Argento 2, drilled to a total depth of 649 metres. The brine aquifer identified was 255 metres thick; a significant increase from the 132 metre aquifer on its maiden well previously reported in its initial NI 43-101 report (see NR February 8, 2022), with an indicated and inferred resource of 1,420,000 tonnes of lithium carbonate equivalent (LCE).



  • The second production well, Argento 2, was drilled 3.6 kilometers southeast of the first production well, Argento 1, which was completed in September 2021.  

  • Argento 2 encountered the target brine aquifer between 343 metres and 598 metres. This equates to a total aquifer of 255 metres thick, or 123 metres thicker than the Company’s initial Argento 1 discovery. 

  • The Company is confident that the proximity between Argento 1 and Argento 2, combined with almost double the thickness of a lithium bearing formation than Argento 1, the estimated lithium resource should be as good or better than the maiden well.  

  • Using a diamond drill rig, Argento 2 was initially drilled to a depth of 450 metres.  The Company then used its contracted rotary drilling rig, set up at the same location, drilling to a total depth of 649 meters using a 9 7/8-inch tricone bit.  

  • Samples taken between 360 metres to 450 metres from the diamond drill hole on Argento 2 returned assays results as high as 350 mg/l lithium. 

  • It is the Company’s intention to install casing into the well, targeting the potential producing zone prior to commencement of aquifer testing and brine sampling. This will provide support to update the estimated 43-101 resource early in the first quarter 2023. 

  • The large rotary rig will mobilize to the new location (shown on Figure 1) to begin drilling the 3rd production well, Argento 3. 


With the knowledge gained from the recent drilling activity on the Company’s Salar de Arizaro project, the Company has contracted another diamond drill rig. Four to five new exploration wells will be drilled to expand testing on other sections of the property. The ongoing exploration program is yielding valuable understanding of the structure and composition of the underlying lithium bearing aquifer.

Steve Cochrane, President, and CEO comments, “The completion of the second production well is a major milestone in Lithium Chiles development. Firstly, moving out 3.6 kilometers and hitting the brine bearing formation just 23 meters deeper in the basin then the first production well is extremely encouraging. Secondly, almost doubling the thickness of the lithium brine aquifer from 132 meters to 255 meters should significantly increase the resource potential on the Salar de Arizaro. My sincere appreciation and congratulations to all the great work our team members are doing in both Argentina and Chile”.
