ACME Lithium Commences TW-1 Pumping Test at Clayton Valley Nevada Lithium Brine Project

Carson City, August 1, 2023 - ACME Lithium Inc. (CSE: ACME) (OTCQX: ACLHF) (the "Company", or "ACME") is pleased to report that the Company has commenced pumping test activities at test well TW-1 at its Clayton Valley Nevada lithium brine project. The well is the only permitted deep well known to currently exist in the northern portion of Clayton Valley.

Data generated from the pumping test will be used to assess hydraulic properties, brine chemistry of the Lower Gravel Unit (LGU) aquifer and to examine the potential concentration and extractability of economic lithium brine in the LGU.

TW-1 was drilled and installed by Harris-Earth Drilling in accordance with Nevada Division of Minerals DMRE well permit W0017. The well was successfully drilled and installed to the target depth of 1,820 feet bgs. Preliminary Phase 1 and Phase 2 data suggest the perforated casing of TW-1 captures approximately 500 feet of potential ore-grade lithium brine aquifer hosted in the LGU. The LGU is the basal gravel overlaying bedrock in Clayton Valley.

The results of the TW-1 pumping test and response propagated to the DH-1A-grouted in vibrating wire piezometer array, will be used to assess the potential volume of lithium enriched brine and extractability of the brine from the LGU aquifer through pumping. 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. Brine samples from the pumping test discharge will be submitted to multiple laboratories for chemical analysis and potential bench-scale testing for Direct Lithium Extraction (DLE) and processing. The TW-1 pumping test, data and laboratory analyses are scheduled to be completed by end of August 2023.

ACME's Clayton Valley Nevada lithium brine project is contiguous to the northwest of Albemarle's Silver Peak lithium deposit which has been in production since 1966 and is one of the only lithium producing regions in the United States.

Forward-looking statements are statements that are not historical facts and are generally, but not always, identified by the words "expects," "plans," "anticipates," "believes," "intends," "estimates," "projects," "potential" and similar expressions, or that events or conditions "will," "would," "may," "could" or "should" occur and in this news release include but are not limited to the attributes of, timing for and expected benefits to be derived from exploration, drilling or development at ACME's project properties. 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.
