ACME Lithium Successfully Completes 10-Day Pumping Test at Clayton Valley Lithium Brine Project

Carson City, Nevada--(Newsfile Corp. - August 17, 2023) - ACME Lithium Inc. (CSE: ACME) (OTCQX: ACLHF) (the "Company", or "ACME") is pleased to report that the Company has successfully completed a 10-day pumping test at test well TW-1 located in Clayton Valley, Nevada. The data generated during the test will be used to estimate the transmissivity and the storativity of the Lower Gravel Unit (LGU) at the TW-1 location. Preliminary Phase 1 and Phase 2 data suggest the perforated casing of TW-1 captures approximately 500 feet of potential lithium brine aquifer hosted in the LGU. The LGU is the basal gravel overlaying bedrock in Clayton Valley.

State permits limited pumping from TW-1 to a maximum rate of 100 gallons per minute (gpm), with total discharge not to exceed 5-acre feet. This permit requirement was strictly adhered to during the test. However, the drawdown measured at a pumping rate of 95 gpm over 10 consecutive days suggests the LGU would sustain significantly higher extraction rates over time, and that TW-1 is in a potential production aquifer in Clayton Valley.

A range of brine samples were collected during the pumping test. These samples were submitted to Nevada certified laboratories for multi-element chemical analyses, to include total and dissolved lithium. Bulk samples were also collected for potential bench-scale testing for Direct Lithium Extraction (DLE) and processing. Preliminary results from the TW-1 pumping test and laboratory analyses are anticipated to be available by end of August 2023.

Intact HQ core recovered from DH-1 was submitted to GeoSystems Analysis Inc. The core was submitted with brine collected from the TW-1 pumping test. The core and brine sample will be used for laboratory testing of drainable porosity (Specific Yield). The results of the laboratory testing of the core samples and the results from the TW-1 pumping test will be used to assess the potential volume of lithium enriched brine and extractability of the brine from the LGU aquifer through pumping. With further evaluation and results pending, the assessment of extractable brine volume and concentration of lithium in the brine will be used to infer if a lithium resource potentially exists at the ACME project.

Information inferred from the interpretation of drilling, sampling and other technical results may also be deemed to be forward-looking statements, as it constitutes a prediction of what might be found to be present when and if a project is actually developed. ACME's project location adjacent to or nearby lithium projects does not guarantee exploration success or that mineral resources or reserves will be defined on ACME's properties. Exploration, development, and activities conducted by regional companies provide assistance and additional data for exploration work being completed by ACME. These forward-looking statements are subject to a variety of risks and uncertainties which could cause actual events or results to differ materially from those reflected in the forward-looking statements, including, without limitation: risks related to fluctuations in metal prices; uncertainties related to raising sufficient financing to fund the planned work in a timely manner and on acceptable terms; changes in planned work resulting from weather, logistical, technical or other factors; the possibility that results of work will not fulfill expectations and realize the perceived potential of the Company's properties; risk of accidents, equipment breakdowns and labour disputes or other unanticipated difficulties or interruptions; the possibility of cost overruns or unanticipated expenses in the work program; the risk of environmental contamination or damage resulting from the Company's operations and other risks and uncertainties.
