His ability to raise capital for potash development and to attract strategic sector partners and off takers, as well as his links into State and Federal government agencies, will help to ensure we have access to appropriate capital as we look to aggressively develop this project as a major potential source of both potash and lithium to strengthen US Domestic Supply Chains of these Critical Minerals.”

About American Critical Minerals’ Green River Potash and Lithium Project

The Green River Potash and Lithium Project is situated within Utah’s highly productive Paradox Basin, located 20 miles northwest of Moab, Utah. It has significant logistical advantages including close proximity to major rail hubs, airport, roads, water, towns and labour markets. It also benefits from close proximity to the agricultural and industrial heartland of America and numerous potential end-users for its products.

The history of oil and gas production across the Paradox Basin provides geologic data from historic wells across the Project, and the wider Basin, validating and de-risking the potential for high grade potash and large amounts of contained lithium. Wells in and around the project reported lithium up to 500 ppm, bromine up to 6,100 ppm and boron up to 1,260 ppm (Gilbride & Santos, 2012). This data is reinforced by nearby potash production and the advanced stage of neighbouring lithium projects. The Paradox Basin is believed to contain up to 56 billion tonnes of lithium brines, potentially the largest such resource in US (Source: AnsonFastmarketsPresentation- https://wcsecure.weblink.com.au/pdf/ASN/02823465.pdf).

The Company’s National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) Potash Exploration Target consists of 500 million to 950 million tonnes of sylvinite (the most important source for the production of potash in North America) grading from 12% to 18% potassium oxide based on elog (eK2O=19% to 29% potassium chloride based on elog (eKCl)). Its Exploration Targets for Lithium and Bromine are 2.1 billion cubic meters (brine volume) grading from 71.6 to 216.3 parts per million lithium; and 2.1 billion cubic meters (brine volume) grading from 3,656 to 4,741 parts per million bromine.**

The Company holds a 100% interest in eleven State of Utah (“SITLA”) mineral and minerals salt leases covering approximately 7,050 acres, 1,094 federal lithium brine claims (BLM Placer Claims) covering 21,150 acres, and 11 federal (BLM) potash prospecting permits covering approximately 25,480 acres. Through these leases, permits and claims the Company has the ability to explore for potash, lithium and potential by-products across the entire Green River Project (approx. 32,530 acres). The Company is authorized to drill a total of 7 drill holes across the Project (pending bonding the recently approved 4 drill holes).

Intrepid Potash, Inc. is America’s largest potash company and only U.S. domestic potash producer and currently produces potash from its nearby Moab Solution Mine, which the Company believes provides strong evidence of stratigraphic continuity within this part of the Paradox Basin ( www.intrepidpotash.com ). Anson Resources Ltd. has advanced lithium development projects contiguous to the northern boundary of our Green River Project and neighbouring to the south. Anson has a large initial resource, robust definitive feasibility study and has recently completed successful piloting operations through its partnership with Koch Technology Solutions, as well as an offtake agreement with LG Energy Solution. The Anson exploration targets encompass the combined Mississippian Leadville Formation and the Pennsylvanian Paradox Formation brine-bearing clastic layers, which also underlie American Critical Minerals’ entire project area ( www.ansonresources.com )*.

In 2022, the U.S. imported approx. 96.5% of its annual potash requirements with domestic producers receiving a higher sales price due to proximity to market (intrepidpotash.com/ August 15, 2024, Investor Presentation). In March 2024, the US Senate introduced a bill to include key fertilizers and potash on the US Department of Interior list of Critical Minerals which already includes lithium, and this process is well advanced with potash being added to the USGS Draft Critical Minerals List. In August 2025. Recent market estimates suggest that the global potash market is over US$50 billion annually and growing at a compound annual growth rate (“CAGR”) of close to 5%. Annual lithium demand is now estimated to be over 1 million tonnes globally and continuing to grow rapidly***.

****Exploration Targets are conceptual in nature and there has been insufficient exploration to define them as Mineral Resources, and, while reasonable potential may exist, it is uncertain whether further exploration will result in the determination of a Mineral Resource under NI 43-101.

Research Capital Corporation (the “Underwriter“) acted as the sole underwriter and sole bookrunner under the Brokered Offering.

The Company is also pleased to announce that it has closed its previously announced concurrent non-brokered private placement, pursuant to which the Company issued 5,714,286 Units at the Offering Price for aggregate gross proceeds to the Company of $2,000,000.10 (the “Non-Brokered Offering” and together with the Brokered Offering, the “Offering“). Together, the Company raised aggregate gross proceeds of approximately $7,451,000 under the Offering.

Simon Clarke, President and CEO stated, “we are very pleased with the level of support that we received for this financing. The Company is now funded to commence confirmation and resource drilling at its Green River Project which is a major milestone for the Company. The location of the project, close to existing potash production and contiguous with advanced lithium development, combined with historic data from numerous oil and gas wells, provides us with a high level of confidence as to the potential of the project. We are now in position to implement the steps needed to confirm that data with the goal of converting our exploration targets to maiden resources for potash, lithium and bromine and to take the project to the next level.”

Each Unit is comprised of one common share of the Company (a “Common Share“) and one-half of one Common Share purchase warrant of the Company (each whole warrant, a “Warrant“). Each Warrant shall entitle the holder thereof to purchase one Common Share at an exercise price of $0.45 per Common Share for a period of 36 months following closing of the Offering, provided that holders will not be permitted to exercise Warrants until 60 days following closing of the Offering.

The net proceeds from the Offering of the Units will be used to launch an initial drill program targeting potash, lithium and bromine at the Company’s Green River Project, focused on confirming and updating historic drill data, and for working capital and general corporate purposes.

The Units issued under the Offering were offered for sale pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106 – Prospectus Exemptions, as amended by CSA Coordinated Blanket Order 45-935 – Exemptions from Certain Conditions of the Listed Issuer Financing Exemption (collectively, the “Listed Issuer Financing Exemption“), in all provinces of Canada, except Quebec, and other qualifying jurisdictions, including the United States. The Units offered under the Listed Issuer Financing Exemption will be immediately “free-trading” under applicable Canadian securities laws.

The Company entered into an underwriting agreement dated November 3, 2025, with the Underwriter, pursuant to which the Company paid the Underwriter a cash commission of 7.0% of the aggregate gross proceeds of the Brokered Offering and such number of non-transferable broker warrants (the “Broker Warrants“) as is equal to 7.0% of the number of Units sold under the Brokered Offering. Each Broker Warrant entitles the holder to purchase one Unit at an exercise price equal to the Offering Price for a period of 36 months following the Closing.

In connection with the Non-Brokered Offering, the Company paid an aggregate cash finder’s fee of $137,882.50 and issued 393,950 Broker Warrants to such finders. The Broker Warrants are subject to a statutory hold period of four months and a day from the closing of the Offering.

Dean Besserer, COO and Director (the “Insider“), participated in the Non-Brokered Offering purchasing 50,000 Units at the Offering Price for gross proceeds of $17,500.00. Participation by the Insider in the Non-Brokered Offering was considered a “related party transaction” pursuant to Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101“) as the Insider is a director and senior officer of the Company. Pursuant to sections 5.5(a) and 5.7(1)(a) of MI 61-101, the Company is exempt from obtaining a formal valuation and minority approval of the Company’s shareholders in respect of the Insider participation due the fair market value of the Insider participation being below 25% of the Company’s market capitalization for the purposes of MI 61-101. The Company will file a material change report in respect of closing of the Offering. However, the material change report will be filed less than 21 days prior to the closing of the Offering, which is consistent with market practice and the Company deems reasonable in the circumstances.

VANCOUVER, BC / ACCESS Newswire / October 28, 2025 / American Critical Minerals Corp. (“American Critical Minerals” or the”Company“) (CSE:KCLI)(OTCQB:APCOF)(Frankfurt:2P3) is pleased to announce that that the Company has filed a National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) Technical Report supporting the Exploration Targets for Potash, Lithium and Bromine for its Green River Potash and Lithium Project, reported in the Company’s news release dated October 6, 2025. The NI 43-101 Report was prepared by Biao Qiu, Ph.D., P.E., P.Eng. and Deliang Han, Ph.D., P.Geo. of Agapito Associates, LLC., dated October 27, 2025. The Exploration Targets have an effective date of September 30, 2025. The filing is voluntary and is not required under NI 43-101 (see Part 4.2(12) of Companion Policy 43-101CP).

The NI 43-101 Report recommends a phased exploration and development program, to build on and confirm historic oil and gas drill data and seismic work, including but not limited to Phase 1: Drilling to test Cycle 5 Potash horizons and test the clastic zones for both Lithium and Bromine within the Paradox and Leadville Formations; complete maiden mineral resource estimates for Potash, Lithium and Bromine; and, complete initial pre-feasibility studies thereon. Phase 2: Additional step out drilling; run a Vertical Seismic Profile (“VSP”) in at least one well for the purpose of generating a synthetic seismogram to improve the analysis of existing two-dimensional (“2D”) seismic interpretation; conduct a 3D seismic survey; complete Lidar Surface mapping; conduct a deep disposal well study; conduct detailed engineering and design; conduct baseline environmental studies; all culminating in a feasibility study and the commencement of permitting. Based on the recommendations, the Company is currently working to develop the phase 1 program of drilling and sampling for the upcoming season.

Simon Clarke President & CEO stated, “We updated the existing technical report to include the recently announced lithium and bromine exploration targets. This also provided an opportunity to include an up-to-date analysis on historic seismic data and to update the prior report for the recent approval of our Plan of Operations, Federal Potash Prospecting Licenses and Drill Authorizations and to update recommendations based on latest developments in the area and exploration in general.

We believe, we now have a very detailed and up to date analysis of our Project and its broader potential. The recommendations from the Report will help form the basis of our upcoming drilling and sampling program where we will drill test the Tier 1 Targets and move towards maiden mineral resources for Potash, Lithium and Bromine”.

• The Existing Seismic Data and interpretation for the Northern Portion of the Property from four 2D Seismic reflection lines has recently been reviewed by Agapito with respect to Potash Cycles 5, 13 and 18 as well as Paradox and Leadville clastic intervals.

• A time structure map of the top of the Paradox Formation salt was constructed.

• Geologic modeling based on tops picked from existing oil and gas wells supports the interpretation of a gentle regional dip in the cycles of interest.

• This interpretation supports relatively flat lying potash cycles (dip approximately 4% to the north) which further supports the potential of suitability for solution mining.

• The data further demonstrates a northward thickening of the Paradox Formation along with high-angle faults, which may correspond to increasing both the quality (through potential chemical enrichment) and the volumetric potential of brines.

VANCOUVER, BC / ACCESS Newswire / October 15, 2025 / American Critical Minerals Corp. (“American Critical Minerals” or the”Company“) (CSE:KCLI)(OTCQB:APCOF)(Frankfurt:2P3) is pleased to announce that Agapito Associates LLC. (“Agapito“) has further reviewed the ExplorTech LLC (2011) Seismic Reflection and Reprocessing Report for the Northern Portion of the Green River Potash and Lithium Project. Full results of this review will also be included in an updated Technical Report on the Green River Potash which will be published shortly.

Simon Clarke President & CEO stated, “Utilizing the large seismic database from oil and gas wells has allowed us to further see the relatively flat lying Paradox and Leadville stratigraphy in the sub-surface of our Green River Project. This has important implications for both Potash and Lithium. Based on this interpretation, the Property appears to be suitable for solution mining wells within the Potash Cycles.

In addition, the clastic zones appear to demonstrate a northward thickening in conjunction with high-angle faulting, which may correspond to increasing both the quality and the volume of the lithium and bromine rich brines. This gives us further confidence in our Exploration Targets as we move rapidly towards drill testing our key targets.

The location of our Green River Project and its proximity to over 50 years of potash production as well as advanced lithium development, already highlights the strategic potential of the Project. In addition, the apparent flat lying nature of its mineralization further validates the potential to successfully develop and mine the potash cycles and the lithium brines.”

Seismic Interpretation (ExplorTech LLC, 2011****)

The Company licensed four (4) 2D seismic lines totaling approximately 32.5 miles from Seismic Exchange (SEI). These lines loosely cover their northwest potash permit area in Grand County, Utah. These seismic data were collected in the late 1960’s with dynamite sources. The data needed to be reprocessed before interpretation. Excel Geophysical (Greenwood Village, Colorado) reprocessed the data. John Arestad of ExplorTech LLC (Centennial, Colorado) interpreted the data. Agapito recently reviewed the data in the context of the Green River Project.

From those interpreted lines, a time structure map of the top of the Paradox Formation salt was constructed by ExplorTech LLC. The map indicates a structural high, likely the Big Flat Dome in the south dipping on a fairly regular slope to the north. This conforms to the regional interpretation from modeling of an overall dip of about four percent (“4%“).

No major faulting, collapses, or diapirism were observed. Minor faulting is identified in the lowermost part of the target Paradox evaporite sequence, while the uppermost part of the evaporite interval, including Cycle 5, showed no interpretable faulting. Faulting extending as high as Cycle 13 is apparent to the southwest.

The seismic data show that faulting is minor within the lowermost part of the target Paradox evaporite sequence. The uppermost part of this interval does not show interpretable faults. The maps produced in the study should be useful for exploration drilling activities. Well prognoses can be made using the interpreted seismic horizons and the existing time-depth data. The hummocky looking appearance of the Paradox salt section suggests that the salt has moved somewhat in the target area and that may have implications for potash recoveries.

The interpretation supports relatively flat lying potash cycles (dip approximately 4% to the north) which further support the possibility of being suitable for solution wells. The data further demonstrates a northward thickening of the Paradox Formation along with high-angle faults, which may correspond to increasing both the quality (through potential chemical enrichment) and the volumetric potential of brines.

The reprocessing and interpretation of these lines is specialized work and may require expertise specific to the Paradox Basin. That said, geologic modeling based on tops picked from existing oil and gas wells supports the interpretation of a gentle regional dip in the cycles of interest. The selection of tops on formations of regional extent such as the Leadville, Hermosa, or Chinle is regarded as straightforward. The Company is further looking to add to this dataset by acquiring additional seismic data licenses.

About American Critical Minerals’ Green River Potash and Lithium Project

The Green River Potash and Lithium Project is situated within Utah’s highly productive Paradox Basin, located 20 miles northwest of Moab, Utah and has significant logistical advantages including close proximity to major rail hubs, airport, roads, water, towns and labour markets. It also benefits from close proximity to the agricultural and industrial heartland of America and numerous potential end-users for its products.

The history of oil and gas production across the Paradox Basin provides geologic data from historic wells across the Project, and the wider Basin, validating and de-risking the potential for high grade potash and large amounts of contained lithium. Wells in and around the project reported lithium up to 500 ppm, bromine up to 6,100 ppm and boron up to 1,260 ppm (Gilbride & Santos, 2012). This data is reinforced by nearby potash production and the advanced stage of development of neighbouring lithium projects. The Paradox Basin is believed to contain up to 56 billion tonnes of lithium brines, potentially the largest such resource in the US

The Paradox Basin is believed to contain up to 56 billion tonnes of lithium brines, potentially the largest such resource in US (Source:AnsonFastmarketsPresentation- https://wcsecure.weblink.com.au/pdf/ASN/02823465.pdf ). The Company also has a 43-101 Exploration Target of 0.6-1.0 billion tonnes (“Bt”) of sylvanite grading from 12% to 18% potassium oxide based on elog (eK2O=19% and 29% potassium chloride based on elog (eKCl).** In addition, the Company also announced Exploration Targets for Lithium and Bromine on 6 October, 2025: 2.1 billion cubic meters (brine volume) grading from 71.6 to 216.3 parts per million lithium; and 2.1 billion cubic meters (brine volume) grading from 3,656 to 4,741 parts per million bromine(see: https://acmineralscorp.com/american-critical-minerals-announces-large-scale-exploration-targets-for-lithium-and-bromine-for-its-green-river-project-complementing-its-existing-exploration-target-for-potash/ )

The Company holds a 100% interest in eleven State of Utah (“SITLA“) mineral and minerals salt leases covering approximately 7,050 acres, 1,094 federal lithium brine claims (BLM Placer Claims) covering 21,150 acres, and 11 federal (BLM) potash prospecting permits covering approximately 25,480 acres. Through these leases, permits and claims the Company has the ability to explore for potash, lithium and potential by-products across the entire Green River Project (approx. 32,530 acres). The Company is authorized to drill a total of 7 drill holes across the Project (pending bonding the recently approved 4 drill holes).

Intrepid Potash, Inc. is America’s largest potash company and only U.S. domestic potash producer and currently produces potash from its nearby Moab Solution Mine, which the Company believes provides strong evidence of stratigraphic continuity within this part of the Paradox Basin (www.intrepidpotash.com). Anson Resources Ltd. has advanced lithium development projects contiguous to the northern boundary of our Green River Project and neighbouring to the south. Anson has a large initial resource, robust definitive feasibility study and has recently completed successful piloting operations through its partnership with Koch Technology Solutions, as well as an offtake agreement with LG Energy Solution. The Anson exploration targets encompass the combined Mississippian Leadville Formation and the Pennsylvanian Paradox Formation brine-bearing clastic layers, which also underlie American Critical Minerals’ entire project area (www.ansonresources.com)*.

In 2022, the U.S. imported approx. 96.5% of its annual potash requirements with domestic producers receiving a higher sales price due to proximity to market (intrepidpotash.com/ August 15, 2024, Investor Presentation). In March 2024, the US Senate introduced a bill to include key fertilizers and potash on the US Department of Interior list of Critical Minerals which already includes lithium, and this process is well advanced with potash being added to the USGS Draft Critical Minerals List. In August 2025. Recent market estimates suggest that the global potash market is over US$50 billion annually and growing at a compound annual growth rate (“CAGR”) of close to 5%. Annual lithium demand is now estimated to be over 1 million tonnes globally and continuing to grow rapidly.

****Exploration Targets are conceptual in nature and there has been insufficient exploration to define them as Mineral Resources, and, while reasonable potential may exist, it is uncertain whether further exploration will result in the determination of a Mineral Resource under NI 43-101.

VANCOUVER, BC / ACCESS Newswire / October 6, 2025 / American Critical Minerals Corp. (“American Critical Minerals” or the”Company“) (CSE:KCLI)(OTCQB:APCOF)(Frankfurt:2P3) is pleased to announce that Agapito Associates LLC. (“Agapito”) has completed the work announced by the Company on July 29, 2025 and has defined a National Instrument (“NI”) 43-101 exploration target for lithium at its Green River Project in the Paradox Basin, Utah. Agapito has also defined a NI43-101 exploration target for bromine as a potentially highly material and large-scale by-product of lithium production. Neighboring Anson Resources has also reported significant Bromine content associated with its lithium brines in the Paradox Basin (www.ansonresources.com).

These Exploration Targets for two critical minerals and a key potential by-product, showcase the large-scale potential of the Green River Project and provide valuable data which the Company will utilize to finalize drill targets for confirmation and resource drilling. In the interim, Agapito is adding these new exploration targets, as well as additional new data, to an updated NI 43-101 Technical Report which the company will publish and file shortly.

The Exploration Target(s) for the Project are based on available geological data, historical drill data from 23 oil and gas wells drilled across and around our Project area (with Lithium and Bromine values) and 18 oil and gas wells (with porosity values) and analogues from adjacent projects. This includes over 50 years pf potash production from the same potash cycles at the nearby Moab Mine, now owned and operated by Intrepid Potash and advanced lithium development work by Anson Resources on contiguous land to our north and adjacent land to our south.

Target tonnages are estimated to range between 1.27 to 2.1 billion cubic meters of brine. Corresponding grades are estimated at 71-216 parts per million (“ppm”) for lithium (1.7 Mt LCE), and 3,656-4,741 ppm for bromine (9.1 Mt Bromine high case). These ranges highlight the prospective nature and potential scale of the mineralized clastic zones. The lower end of the target range from 42.9ppm to 129.8ppm lithium (0.6 Mt LCE) and 2194 to 2844 ppm bromine (3.3 Mt Bromine Low Case). The upper end with grades up to 29% eKCl, 152 ppm Lithium, and 4,412 ppm Br₂ reflects the upside potential should continuity and thickness be confirmed through further drilling. These estimates provide a framework for prioritizing exploration activities, including step-out drilling and detailed geophysical interpretation.

Management Commentary

Simon Clarke President & CEO stated, “this is a big milestone for the Company. The importance of lithium and bromine in the Paradox has been recognized for a number of years but has been very much highlighted and validated in recent times by our close neighbour Anson Resources. The work they have done on drilling and successfully piloting their projects and attracting definitive offtake partners like LG Solution for battery grade lithium, is potentially directly applicable to, and positive for, our Green River Project given their land is contiguous and adjacent to ours. The work now done by Agapito in defining exploration targets for lithium, and also bromine takes this potential a step further and showcases the large-scale potential of the Green River Project for lithium and bromine based on a lot of additional historic and recent data.

The potential of our Project is even larger than our neighbours, given we also have large-scale potash potential and a large existing exploration target for potash. We now have 3 large exploration targets for 3 different minerals, as well as drill permits in hand and we can test for all 3 minerals in each hole we drill. This latest work further positions the Company to launch confirmation and resource drilling in the coming months.”

Lithium and Bromine Exploration Targets

The Exploration Target estimate for lithium and bromine is based on brine-hosting intervals within the Paradox Basin. Key geologic units, including the Leadville Formation and Paradox clastic zones 17, 19, 29, 31, and 33, were evaluated individually using available porosity, volume, and brine chemistry data to establish potential ranges for contained lithium and bromine.

The Pennsylvanian-age Paradox Formation comprises thick, regionally extensive halite units interbedded with evaporitic anhydrite and potash horizons, as well as clastic and carbonate intervals including sandstone, shale, limestone, and dolomite. Core data published from Anson Resources’ Paradox Lithium and Green River Lithium Project areas provide direct petrophysical and lithological measurements that can be correlated to the clastic zones identified within the Green River Project area. These datasets confirm the lateral continuity and stratigraphic equivalency of the principal reservoir intervals. Eighteen drillholes from adjacent project areas that report porosity values, which are considered representative values for the Green River Property clastic zones. Effective porosity ranges of 10.3-17.1%, 11.0-18.4%, 9.9-16.4%, and 12.4-20.7% were assigned to Clastic Zones 17, 19, 29, 31, and 33, respectively, with the reported values representing average effective porosity estimates for each interval.

The Mississippian Leadville Formation is a marine carbonate sequence that is typically composed of limestone and dolomite. Because the Leadville currently and historically has been a target for hydrocarbons, CO2 and helium, there is abundant well data available. At the Green River Property, the Leadville has been shown to have excellent vuggy porosity and good reservoir deliverability. A range of 5.1% – 8.5% average effective porosity was used for the Mississippian Leadville Formation.

In total, 23 drillholes from adjacent project areas reporting lithium and bromine concentrations, which are interpreted as representative values for the Green River Property clastic zones and the Mississippian Leadville Formation. Average lithium concentration ranges of 42.9-71.6 ppm, 86.1-143.4 ppm, 76.1-126.9 ppm, 129.8-216.3 ppm, 47.6-79.4 ppm, and 120.8-201.3 ppm were applied to Clastic Zones 17, 19, 29, 31, 33, and the Mississippian interval, respectively. Corresponding average bromine concentration ranges of 2,551-4,251 ppm, 2,333-3,888 ppm, 2,508-4,180 ppm, 2,587-4,311 ppm, 2,194-3,656 ppm, and 2,845-4,741 ppm were assigned to the same stratigraphic units in order.

The two tables, designated as Tables 1 and 2, present a range of potential in situ mineral quantities for an exploration target containing lithium and bromine brines. These tables define the estimates for a High Case (Table 1) and a Low Case (Table 2) scenario, a standard practice in mineral exploration to bracket the potential resource based on the current level of geological knowledge and data uncertainty. The foundational calculation for both estimates begins with the geometric properties of the aquifer, specifically its total volume. This aquifer volume is then combined with a range of effective porosity values-a lower percentage for the conservative Low Case and a higher percentage for the optimistic High Case-to calculate the total volume of brine potentially hosted within the rock pores.

The subsequent calculations apply grade estimates to these brine volumes to determine the total contained metal. For instance, a Low Case brine volume of 25 million cubic meters multiplied by a conservative lithium grade of 200 parts per million could yield a total lithium metal estimate on the order of tens of thousands of tonnes. This lithium figure is also converted into its Lithium Carbonate Equivalent (LCE), the industry-standard unit for commercial transactions, which could range from a Low Case in the realm of 615,000 tonnes to a High Case potentially exceeding 1,710,000 tonnes. Simultaneously, the bromine content is calculated using its own range of concentration values, potentially resulting in a Low Case estimate of approximately 3,288,000 tonnes of elemental bromine (Br₂) and a significantly larger High Case figure of 9,134,000 tonnes. The substantial spread between the low and high estimates for both minerals effectively captures the geological uncertainties at this early stage, serving to illustrate the potential scale of the discovery and guide future exploration efforts to better define the resource.

About American Critical Minerals’ Green River Potash and Lithium Project

The Green River Potash and Lithium Project is situated within Utah’s highly productive Paradox Basin, located 20 miles northwest of Moab, Utah and has significant logistical advantages including close proximity to major rail hubs, airport, roads, water, towns and labour markets. It also benefits from close proximity to the agricultural and industrial heartland of America and numerous potential end-users for its products.

The history of oil and gas production across the Paradox Basin provides geologic data from historic wells across the Project, and the wider Basin, validating and de-risking the potential for high grade potash and large amounts of contained lithium. Wells in and around the project reported lithium up to 500 ppm, bromine up to 6,100 ppm and boron up to 1,260 ppm (Gilbride & Santos, 2012). This data is reinforced by nearby potash production and the advanced stage of neighbouring lithium projects. The Paradox Basin is believed to contain up to 56 billion tonnes of lithium brines, potentially the largest such resource in US (Source:AnsonFastmarketsPresentation- https://wcsecure.weblink.com.au/pdf/ASN/02823465.pdf ). The Company also has a 43-101 Exploration Target of 600 million to 1 billion tonnes of sylvinite (the most important source for the production of potash in North America) with average grades ranging from 19% to 29% eKCL.**

The Company holds a 100% interest in eleven State of Utah (“SITLA”) mineral and minerals salt leases covering approximately 7,050 acres, 1,094 federal lithium brine claims (BLM Placer Claims) covering 21,150 acres, and 11 federal (BLM) potash prospecting permits covering approximately 25,480 acres. Through these leases, permits and claims the Company has the ability to explore for potash, lithium and potential by-products across the entire Green River Project (approx. 32,530 acres). The Company is authorized to drill a total of 7 drill holes across the Project (pending bonding the recently approved 4 drill holes).

Intrepid Potash, Inc. is America’s largest potash company and only U.S. domestic potash producer and currently produces potash from its nearby Moab Solution Mine, which the Company believes provides strong evidence of stratigraphic continuity within this part of the Paradox Basin (www.intrepidpotash.com). Anson Resources Ltd. has advanced lithium development projects contiguous to the northern boundary of our Green River Project and neighbouring to the south. Anson has a large initial resource, robust definitive feasibility study and has recently completed successful piloting operations through its partnership with Koch Technology Solutions, as well as an offtake agreement with LG Energy Solution. The Anson exploration targets encompass the combined Mississippian Leadville Formation and the Pennsylvanian Paradox Formation brine-bearing clastic layers, which also underlie American Critical Minerals’ entire project area (www.ansonresources.com)*.

In 2022, the U.S. imported approx. 96.5% of its annual potash requirements with domestic producers receiving a higher sales price due to proximity to market (intrepidpotash.com/ August 15, 2024, Investor Presentation). In March 2024, the US Senate introduced a bill to include key fertilizers and potash on the US Department of Interior list of Critical Minerals which already includes lithium, and this process is well advanced with potash being added to the USGS Draft Critical Minerals List in August 2025. Recent market estimates suggest that the global potash market is over US$50 billion annually and growing at a compound annual growth rate (“CAGR”) of close to 5%. Annual lithium demand is now estimated to be over 1 million tonnes globally and continuing to grow rapidly.

****Exploration Targets are conceptual in nature and there has been insufficient exploration to define them as Mineral Resources, and, while reasonable potential may exist, it is uncertain whether further exploration will result in the determination of a Mineral Resource under NI 43-101.

VANCOUVER, BC / ACCESS Newswire / September 29, 2025 / American Critical Minerals Corp. (“American Critical Minerals” or the”Company“) (CSE:KCLI)(OTCQB:APCOF)(Frankfurt:2P3) is pleased to confirm that it has made the required annual payments to renew its 100% interest in 11 State of Utah (“SITLA“) Mineral and Minerals Salt Leases covering approx. 7,050 acres, 1,094 Federal Lithium Brine Claims (BLM Placer Claims) covering approx. 21,150 acres, and 11 Federal (BLM) Potash Prospecting Permits covering approx. 25,480 acres. Through these leases, permits and claims the Company has the ability to explore for, and develop, potash and lithium and associated by-products (including Bromine and Boron) across the entire Green River Project (approx. 32,530 acres).

The Company has Permits in place to drill 3 holes on its State of Utah Leases following the payment of required reclamation bonding in respect of these holes. In addition, under the Plan of Operations approved by the BLM in October 2024, the Company is also authorized to drill 4 holes across its Federal (BLM) acreage. The Company has now finalized with the BLM and the Utah Department of Natural Resources, the additional reclamation bonding required to receive final permits to drill these 4 additional holes. Once this additional bonding is paid by the Company it will be in position to drill up to 7 holes in total across the Green River Project.

Unlike its near neighbors, who are focused on either potash production (Intrepid Potash: https://www.intrepidpotash.com) or advanced lithium development (Anson Resources: https://www.ansonresources.com), the Company is looking to develop both potash and lithium. Historic oil and gas wells, and development work contiguous to the Company’s Green River Project, have highlighted the potential for both Critical Minerals and the Company will test for both potash and lithium in each hole it drills. * **

Management Commentary

Simon Clarke President & CEO stated, “we are pleased to continue to make strong progress operationally as we continue to position the Company to launch drilling to confirm the historic values obtained in the oil and gas wells drilled across, and around, our acreage. We will be targeting the same potash cycles that our near neighbour, Intrepid Potash, has been producing from for decades and given our Project is contiguous with Anson’s project to the North and adjacent to their project to the South, we are highly confident that “as the meat in the sandwich” we will experience similar results on the lithium side. Speaking of Anson, I would like to commend them for their continued strong performance. Their MOU with POSCO Holdings and their definitive offtake agreement with LG Energy Solution, both major players in the lithium-Ion Battery space, are impressive and provide strong validation of the Paradox Basin as a major source of high-quality lithium.

In the interim, we are excited to continue to progress work with Agapito Associates LLC (announced in late July 2025) to define a 43-101 Exploration Target for lithium reflecting the growing importance of lithium in the Paradox and its potential at Green River. This work will also lead to our 43-101 Technical Report** being updated and refreshed and will provide us with 43-101 Exploration Targets for both critical minerals as we position ourselves for confirmation and resource Drilling. We expect to be able to finalize this work with Agapito in the near future.”

Granting of Incentive Securities

The Company also announces that it has granted an aggregate of 660,000 incentive stock options (the “Options”) to certain of its directors, officers and key advisors. The Options vest over a period of one year and each Option is exercisable to acquire one common share at $0.38 for a period of 5 years from the date of grant. In addition, the Company has granted an aggregate of 540,000 Restricted Share Units (“RSUs”) to certain of its directors, officers and key advisors. The RSUs vest and convert into an equivalent number of common shares after thirty-six months, subject to accelerated vesting in the event the closing price of the common shares of the Company is $0.875 or greater at any time, or upon the occurrence of a change of control event for the Company.

About American Critical Minerals’ Green River Potash and Lithium Project

The Green River Potash and Lithium Project is situated within Utah’s highly productive Paradox Basin, located 20 miles northwest of Moab, Utah and has significant logistical advantages including close proximity to major rail hubs, airport, roads, water, towns and labour markets. It also benefits from close proximity to the agricultural and industrial heartland of America and numerous potential end-users for its products.

The history of oil and gas production across the Paradox Basin provides geologic data from historic wells across the Project, and the wider Basin, validating and de-risking the potential for high grade potash and large amounts of contained lithium. Wells in and around the project reported lithium up to 500 ppm, bromine up to 6,100 ppm and boron up to 1,260 ppm (Gilbride & Santos, 2012). This data is reinforced by nearby potash production and the advanced stage of neighbouring lithium projects. The Paradox Basin is believed to contain up to 56 billion tonnes of lithium brines, potentially the largest such resource in US (Source: Anson Fastmarkets Presentation – https://wcsecure.weblink.com.au/pdf/ASN/02823465.pdf ) The Company also has a 43-101 Exploration Target of 600 million to 1 billion tonnes of sylvinite (the most important source for the production of potash in North America) with average grades ranging from 19% to 29% KCL.**

The Company holds a 100% interest in eleven State of Utah (“SITLA“) mineral and minerals salt leases covering approximately 7,050 acres, 1,094 federal lithium brine claims (BLM Placer Claims) covering 21,150 acres, and 11 federal (BLM) potash prospecting permits covering approximately 25,480 acres. Through these leases, permits and claims the Company has the ability to explore for potash, lithium and potential by-products across the entire Green River Project (approx. 32,530 acres). The Company is authorized to drill a total of 7 drill holes across the Project (pending bonding the recently approved 4 drill holes).

Intrepid Potash, Inc. is America’s largest potash company and only U.S. domestic potash producer and currently produces potash from its nearby Moab Solution Mine, which the Company believes provides strong evidence of stratigraphic continuity within this part of the Paradox Basin (www.intrepidpotash.com). Anson Resources Ltd. has advanced lithium development projects contiguous to the northern boundary of our Green River Project and neighbouring to the south. Anson has a large initial resource, robust definitive feasibility study and has recently completed successful piloting operations through its partnership with Koch Technology Solutions, as well as an offtake agreement with LG Energy Solution. The Anson exploration targets encompass the combined Mississippian Leadville Formation and the Pennsylvanian Paradox Formation brine-bearing clastic layers, which also underlie American Critical Minerals’ entire project area (www.ansonresources.com)*.

In 2022, the U.S. imported approx. 96.5% of its annual potash requirements with domestic producers receiving a higher sales price due to proximity to market (intrepidpotash.com/ August 15, 2024, Investor Presentation). In March 2024, the US Senate introduced a bill to include key fertilizers and potash on the US Department of Interior list of Critical Minerals which already includes lithium, and this process is well advanced with potash being added to the USGS Draft Critical Minerals List. In August 2025. Recent market estimates suggest that the global potash market is over US$50 billion annually and growing at a compound annual growth rate (“CAGR”) of close to 5%. Annual lithium demand is now estimated to be over 1 million tonnes globally and continuing to grow rapidly. * **
