Lisbon Valley, Utah DLE Project Mining process currently accounts for roughly half the carbon footprint of a battery cell and the best way to reduce the carbon footprint of minerals is to stop shipping them across 9,000 kilometers of ocean before refining them.” - Tesla Chairwoman Robyn Denholm OTC: BLTH | 10

Flagship Lithium DLE Project DLE mitigates environmental concerns relating to lithium extraction Technical reports show supersaturated brines of 1,700 ppm LCE (340 ppm Li) Li Developed infrastructure, including high voltage electrical, roads and access to rail lines Located in Eastern Utah consisting of 120+ mineral rights across 2,040 Acres of Federal land, including 7 existing wells Historical data shows supersaturated brine (40% minerals, 60% water) with reported Lithium values ranging from 81 to 1700ppm and estimated flows >50,000 barrels of brine per day Lisbon Valley, Utah OTC: BLTH | 11 ABM’s property position consists of 120+ placer mining claims staked in one contiguous group on U.S. Government lands administered by the U.S. Bureau of Land Management (BLM)

Project l o c a t i o n The Uniquely - Positioned Paradox Basin With over 300+ climate friendly days and a fully developed infrastructure, the Paradox Basin is one of the most attractive places in the U.S. for a successful and efficient extraction process. 25 miles southwest of Moab Not adjacent to any national parks or recreational sites Area is a mix of federal, state and private lands High desert climate with year - round access Historically rich industrial and natural resource extraction area OTC: BLTH | 12

Lisbon Assets Technical Report The brines were not thought to be important until 1962, when Southern Natural Gas intersected the brine zone with a very substantial flow of brines under tremendous pressure . There is abundant evidence from oil and gas and potash wells drilled in the Paradox Basin that indicate that there is a high probability of intersecting super saturated brines . It is believed that there is a substantial indication that lithium mineralization in brines occurs beneath the subject property . There is also substantial evidence that other valuable minerals besides lithium, such as potassium, magnesium, calcium chloride, bromine and boron, may be recoverable from the brines, as well. – Prepared by Peek Consulting, Inc.

Direct Li Extraction & the American Environment DLE offers significant promise of increasing supply, reducing the industry’s environmental, social, and governance (ESG) footprint, and lowering costs, with already announced capacity contributing to around 10 percent of the 2030 lithium supply, as well as to other less advanced projects in the pipeline.” – McKinsey & Company OTC: BLTH | 16

DLE vs. Traditional Lithium Mining ABM will deploy DLE in selective brine extraction to provide a cost - effective, efficient, faster - to - production, and significantly more environmentally friendly method versus traditional mining practices. American dependency on foreign lithium has reached crisis levels. DLE addresses this critical need without destroying the earth. Direct Lithium Extraction (DLE) Traditional Lithium mining faces major hurdles with important considerations of environmental damage, regulatory issues, controversial mining practices and territorial litigation. The environmental toll has often been overlooked in part because there is a race underway among the United States, China, Europe and other major powers.” – NYTimes Underground brine Conventional evaporation ponds (~2 years) ABM Direct Lithium Extraction (DLE) (~2 h) L i 2CO 3 Mg/Ca re m o v al Boron removal L i Cl ESG OTC: BLTH | 17

The Engineering Behind DLE Targeting Highly Efficient Direct Lithium Extraction (DLE) Technology ABM is evaluating leading DLE technology companies • The most technologically advanced approach for DLE from brines is adsorption of lithium using inorganic sorbents • Extraction of lithium with inorganic molecular sieve ion - exchange sorbents appears to offer one of the most immediate pathways for the development of economic lithium extraction Competitive advantages of the technology • Reduced impurities – by over 99% • Rapid and high recovery • Low energy consumption • No evaporation • Lower water consumption • Not weather dependent • Smaller environmental footprint Extraction of brine Re - injection of lithium deprived brine Li Salts Saline Aquifer Produced Brine Components Direct Lithium Extraction Lithium I n j ect i on well P roduct i on w e ll x x F e F e N a N a L i M g C a S i S i M g C a S N i a M L g i C a F e L L L i i i L i F e N a M g C a S i Lithium deprived spent brine Pumping of native brine Saline Aquifer N on - evapor i t ic Extractive Method X Solar Panel OTC: BLTH | 18

DLE lowers greenhouse gas emissions, leaving a substantially lower carbon footprint than traditional extraction methods DLE reduces the land requirements by over 97% when compared to evaporation and hard - rock projects DLE reduces waste production with no tailings, ponds or open pits, and returns 100% of the brine brought to the surface to similar depths in a closed loop system DLE extracts brackish water far below the water table and with salinity levels that significantly exceed any acceptable levels for human or animal consumption DLE reduces the overall amount of time needed for the lithium extraction process DLE removes the need for large fresh water sources Environmental & Economic Advantages of DLE Closed Loop DLE Production from geothermal deposits could be the holy grail of sustainable lithium production, providing both clean geothermal energy and a source of lithium. Fastmarkets estimates put 168 ktpa LCE of geothermal capacity in the pipeline, with potential for a further 280 ktpa LCE from one project alone.” – Fastmarkets OTC: BLTH | 19

This ultimately allows ABM to shorten its time to market over other resource - heavy mining projects, pointing to an anticipated shorter return on investment. ABM is positioned far ahead of new and developing lithium projects, including area selection, permitting and partner selection. ABM has the significant advantage of being one of the first to market with a U.S. brine that is available for DLE brine extraction pilot programs. DLE extraction methods have successfully been utilized in other industries such as Water Treatment and Oil Waste for decades. Est. Project Length in Years 8 - 15 OTC: BLTH | 20
