American Battery Technology Company (ABTC)—an integrated critical battery materials company that is commercializing its technologies for both primary battery minerals manufacturing and secondary minerals battery recycling—is pleased to announce positive drill results from its third exploration drill program at its Tonopah Flats Lithium Project in Big Smoky Valley, Nevada. The infill and step-out drill program comprised 8 holes totaling approximately 6,700 feet of sampling. It achieved the target core drilling depth of over 1,400 feet, one of the deepest lithium sampling activities in the region. To date, the company has received third-party assay results for 6 of the 8 holes, with results further supporting the development of this domestic resource towards upgraded Measured and Indicated classifications.

“It is extremely rare to identify a resource where nearly every sample taken at depth is above its minimum cutoff concentration, and we are extremely pleased that the assay results of our initial 6 holes of our 8-hole third drill program continue to demonstrate that this is one of the premier lithium resources in the United States,” stated ABTC CEO Ryan Melsert. “From the data we published in the Spring in our SK-1300 compliant Maiden Resource Report, it was already identified that this is one of the largest known lithium resources in the United States, and with the additional step-out drilling in this program, we have even further expanded this data set, both with respect to surface and to depth.  Additionally, the infill drilling within our already identified resource area that was recommended within our last resource report supports advancement of this resource towards upgraded Measured and Indicated classifications.”

This drill program has confirmed the presence of mineralization between step-out holes with infill drilling.

Highlights from this third drill program

High Lithium Concentrations Above Cutoff: The vast majority of samples analyzed, up to 99% per hole, demonstrated lithium concentrations above the reference cutoff concentration of 300 ppmw. These intervals of high concentrations were observed in all 6 holes and throughout a large percentage of the total sampled depths, and with significantly higher peak concentrations observed in many sample holes (see Table 1), which makes this deposit especially attractive to the internally-developed ABTC processing train.

Shallow Overburden: Anomalous lithium concentrations were measured at very shallow depths, less than 20 feet below the surface in many cases, indicating that low-cost and low-strip ratio techniques can likely be applied to access these near-surface lithium-bearing sedimentary materials.

Depth of Mineralization: The drilling infrastructure employed in these explorations was able to drill to depths of up to 1,430 feet, and in several of these drill holes the significant mineralization of lithium is still present at these depths, indicating that the anomalous lithium presence could extend even beyond the sampled depths.

Breadth of Exploration: With these additional 6 drill holes, a wide breadth of ABTC claims have been explored, including over 18,000 feet of exploration at depths of up to 1,430 feet.

Magnitude of Deposit: With the anomalous lithium concentrations observed throughout the detailed exploratory drill holes, and throughout the listed sampling depths, the ABTC team is excited to receive the assay results of the remaining 2 holes, and to accelerate the exploration and characterization of these claims to take the further steps necessary to advance this deposit to a Measured and Indicated resource through an updated S-K 1300 compliant Resource Report process.

“We are extremely proud of our team in Tonopah, as we now have identified the Upper, Middle, and Lower Siebert formation geologically in the basin,” stated Scott Jolcover, chief mineral resources officer for American Battery Technology Company.  “Our previous deepest hole was 825 feet, and we have now sampled at over 1,400 feet deep, with assay results received for 6 holes in this 8-hole program. All drilled holes have appeared to bottom in claystone with very shallow alluvium gravels at the top of the holes and we look forward to receiving the remaining assay results.”

The ABTC Tonopah Flats Lithium Project encompasses 517 unpatented lode claims covering over 10,340 acres, and ABTC controls 100% of the mining lode claims comprising the Tonopah Flats claims and the rights to all locatable minerals without any royalties. ABTC began surface sampling of these claims in the Summer of 2021, and subsequently performed multiple subsurface drilling programs at depths of up to 1,430 feet totaling over 18,000 feet of exploration.

The results of these initial successful exploration programs led to the development and publication of the company's third-party Qualified Person (QP) audited SK-1300 compliant Maiden Resource Report in February 2023, which concluded that this deposit is one of the largest known lithium resources in the United States, containing approximately 15.8 million tons of economically-accessible lithium on a carbonate equivalent basis (LCE).  As the remaining assay results are received, the company intends to prepare and publish an updated Resource Report with updated quantities of the resource that are at the inferred, measured and indicated classifications.
