One of the Largest Known Lithium Deposits in US Identified at American Battery Technology Company Tonopah Flats Property - Inferred Resource Estimated through S-K 1300 Compliant Study Feb 28, 2023, 09:09 ET Third-party audited analysis estimates inferred resource of 15.8 million tons of lithium carbonate equivalent RENO, Nev., Feb. 28, 2023 /PRNewswire/ -- American Battery Technology Company (ABTC) (OTCQX: ABML), an American critical battery materials company that is commercializing both its primary minerals manufacturing and secondary minerals lithium-ion battery recycling technologies, announced results of its third-party Qualified Person (QP) audited Inferred Resource Report that details the analysis of its lithium deposit at its Tonopah Flats Lithium Project in Big Smoky Valley, Nev., which has resulted in the identification of one of the largest known lithium deposits in the United States. The ABTC Tonopah Flats Lithium Project encompasses 517 unpatented lode claims covering approximately 10,340 acres, and ABTC controls 100% of the mining lode claims comprising the Tonopah Flats property and the rights to all locatable subsurface minerals without any royalties. ABTC began surface sampling of these claims in the Summer of 2021, and subsequently performed multiple subsurface drilling programs totaling 12,000 feet of exploration covering approximately 65% of its property. In order to perform an unbiased analysis of this data, the mineral resource estimates presented in the ABTC Tonopah Flats Inferred Resource Report were performed by third-party qualified person (QP) RESPEC, LLC, and were classified by geological and quantitative confidence in accordance with the Securities and Exchange Commission (SEC) Regulation S-K 1300. Through this analysis an open-pit resource estimate was developed that would support a processing rate of at least 200,000 tons of claystone per day. "Having identified one of the largest premier lithium deposits in the U.S. is extremely exciting," stated ABTC CEO Ryan Melsert. "However, the identification of an inferred resource in and of itself is not enough to address our critical challenges of increasing our domestic production of critical battery metals, reducing the costs of manufacturing of these battery metals, and decreasing the environmental impacts of their production." Melsert continued, "The development of a resource needs to be paired with the development of targeted technologies for the extraction of these metals, and we are proud to have spent the past several years developing technologies specifically targeted at these Nevada-based claystone lithium resources and to have been recognized by the U.S. Department of Energy for the performance of these technologies through our selection for a competitive R&D scale grant in 2021 and for a competitive grant to construct a commercial scale claystone lithium hydroxide refinery in 2022." Report Highlights
Tonopah Flats Mineral Resource Estimate
The mineral resource estimates for the ABTC Resource Report were classified by geological and quantitative confidence in accordance with the SEC Regulation S-K 1300. The mineral resources for Tonopah Flats described and tabulated in this report are entirely classified as Inferred and were estimated to reflect potential open-pit extraction. The lithium resources at Tonopah Flats were modeled and estimated by:
Status of Exploration, Development, and Operations Exploration conducted by ABTC commenced in the Summer of 2021 and has included both surface sampling and drilling. ABTC collected 29 surface samples in June 2021 to confirm elevated lithium values from samples collected by a previous owner. The surface samples returned an average of 314 ppm lithium with a maximum of 882 ppm lithium. ABTC commenced drilling at the Tonopah Flats property in December of 2021. A total of 12,000 feet were drilled in 10 reverse circulation holes and 12 air core holes during two phases of drilling prior to October of 2022. Drill holes were spaced approximately 200 ft to 3,500 feet apart. All holes were drilled vertically and ranged from 400 to 885 feet in depth. Lithium mineralization was encountered in all 21 drill holes submitted for analysis. Metallurgical Testing and Mineral Processing The Tonopah Flats deposit is comprised of lithium-rich sedimentary claystone with negligible work index and abrasion, and readily disaggregates when suspended in water. Standard assaying of head grades was performed using a representative array of samples selected from 21 drill holes. For metallurgical leaching trials, bulk samples from the Tonopah Flats project were prepared for lithium leach trials using roughly 700 pounds of cuttings from the 2021-2022 drill hole program. These metallurgical leaching trial samples were collected from drill hole TF-2208, where the average head-grade for lithium was found to be about 790 ppm. The sample was homogenized by cone-and-quarter methods and pulverized to 100 mesh to obtain a statistically repetitive sample. Mineral processing was carried out at the University of Nevada, Reno's Ore Dressing Laboratory. The claystone is responsive to dilute acid leaching as well as several methods of selective lithium leaching. Leaching trials were carried out in-house by ABTC using statistically representative homogenized bulk samples, and these trials demonstrated that over 90% of lithium can be leached from the claystone within a few hours. Following leaching, treatment of the pregnant leaching solution by pH adjustment/neutralization, filtration, solution purification, concentration, conversion, and final solution polishing/crystallization, battery grade lithium hydroxide monohydrate can be realized. To further validate and optimize these metallurgical and mineral processing techniques, ABTC summarized the results of its bench scale trials for the manufacturing of battery grade lithium hydroxide specifically from these Nevada-based claystone materials in a $4.5M proposal to the U.S. Department of Energy (DOE), Advanced Manufacturing Office (AMO). In this application, the ABTC team and its partner, DuPont Water Solutions, described its integrated mineral processing train in detail and proposed a plan for evolving these bench scale trials to a multi-ton per day continuous integrated field pilot plant to demonstrate the performance and economics of the overall system. In January 2021, ABTC was notified that the U.S. DOE AMO had selected its proposal for funding and the projected initiated in October 2021. Substantial trials, validations, and optimizations of these mineral processing unit operations have been performed to date within this government supported project. Due to the positive results from these bench scale validations, the ABTC team applied for a second round of U.S. DOE funding in the Spring of 2022 to further evolve this project and to construct a commercial scale lithium hydroxide refinery utilizing this system design and the bench and pilot scale results from the initial program. In October 2022, ABTC with its partners, DuPont Water Solutions, University of Nevada, Reno, and Argonne National Laboratory, was notified that its proposal for its $115M commercial scale refinery project was selected for funding. ABTC is now in the process of detailed construction design for this commercial scale lithium hydroxide refinery based on these fundamental metallurgical and mineral processing techniques. "We are extremely pleased with the results of our Resource Report for our Tonopah Flats Lithium Project," commented Scott Jolcover, ABTC Chief Mineral Resource Officer. "Our team mobilized quickly to accomplish several initial key steps to mature this resource. There are several steps remaining to pursue as we progress the project and we are moving forward with recommended next steps to advance the project through the feasibility stage." Next Steps With the data generated in this report, ABTC intends to take the following steps to further advance this project.

Inferred Resource Inferred mineral resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve.
