ACME Lithium Announces New Lithium Discovery at Clayton Valley, Nevada

Carson City, August 17, 2022 - ACME Lithium Inc. (CSE: ACME) (OTCQB: ACLHF) (the "Company", or "ACME") is pleased to report positive sample results from the recently drilled DH-1 hole at its Clayton Valley lithium brine project located in Esmeralda County, Nevada. The Company's significant new lithium discovery has initiated Phase 2 planning and procurement of an expanded drilling and pump test program.

DH-1 was drilled to a total depth of 1400 feet (427) meters below ground surface and intersected multiple productive horizons including the targeted basal gravel aquifer at an approximate depth of 1,250 feet (381 meters) below ground surface (bgs).

Samples of brine were taken from DH-1 at various intervals and were sent to an independent lab and analyzed for lithium and other elements typical of lithium enriched brine systems. Target sampling zones and depths were based on the results of the geophysical surveys, interpretations of the drilled lithology, and field observations including fluid conductivity and salt precipitation on the exposed core.

The following provides a summary and preliminary assessment of the laboratory analytical results and lithium assays from DH-1:

• Lithium was detected from all brine samples at concentrations ranging between 38 and 130 mg/L.
• Boron was also detected from all brine samples with concentrations ranging between 16 and 39 mg/L.
• The results strongly indicate existence of a bicarbonate rich groundwater quality affinity which is typical in the Clayton Valley lithium brine aquifers.
• Lithium concentrations appear to increase in the vicinity of the deeper lacustrine tuff unit at 1,180 feet bgs and increases further to 130 mg/L in the deep gravels underlaying the tuff near the bottom of the hole.
• The assay results indicate lithium concentrations likely increase with depth and with temperature.
• The highest concentrations (130 mg/L) were from samples collected in the deep gravels at 1,350 feet and at 1,400 feet bgs.

Additional aquifers were intercepted above the basal gravel layer including the main ash layer which is believed to be one of the targeted production horizons of Albemarle's neighbouring Silver Peak lithium project.

A preliminary assessment of major contacts encountered in DH-1 as they may apply to those described in regional historical data is provided below:

• 0 to 181' Upper Clastic Unit (UCU)
• 181 to 195' Main Ash Unit (MAU)
• 195 to 479' Lower Clastic Unit (LCU)
• 479 to 1,180' Lower Gravel Unit LGU/LCU
• 1,180 to 1,250' Airfall Ash - Lacustrine Tuff (CAU)
• 1,250 to 1,400 Transition Between LCU/LGU

Geologic and geophysical data including sample results will help identify specific horizons to be tested in a Phase 2 drill program which will include a separate, larger diameter test well (TW-1) for completion of brine aquifer permeability testing and sampling. Phase 2 will also include up to three (3) new exploration holes DH-1A, DH-2, and DH-3 with objectives to examine deeper horizons through zonal isolated testing, assess stratigraphy, and the potential for continuity between the stratigraphic units encountered in DH-1. The Phase 2 exploration holes will be completed with grouted in vibrating wire piezometers which will be used to monitor aquifer response during future pumping test. Phase 2 is expected to commence during the 4^th quarter of 2022 subject to further permitting and availability of drilling equipment and services.

Based on prior Clayton Valley drilling experience intercepting a high-flow brine horizon marking the gravel/bedrock contact, ACME's team is particularly focussed on advancing drilling to test this highly prospective brine zone.

ACME's Clayton Valley, Nevada lithium brine project is contiguous to the northwest of Albermarle's Silver Peak lithium deposit which has been in production since 1966. Located in one of the best resource jurisdictions in the world, Clayton Valley is the only lithium producing region in the United States.

ACME is well funded by strategic investors and positioned to complete its exploration and development objectives thru the near term with the goal of providing a domestic supply of lithium to the US and Canadian markets.
