AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 4 |
I. EXECUTIVE SUMMARY
A. Introduction
A very large manganese, cobalt, nickel, and copper resource occurring as polymetallic nodules is located on the seafloor in the Southern Pacific Ocean adjacent to the Exclusive Economic Zone of the Cook Islands. American Ocean Minerals Corporation (AOM) is a Delaware Limited Liability Company, undertaking assessment on the technical and economic viability of recovering metals from polymetallic nodules from two non-contiguous Subareas (Subareas North and South, together named “Area 2”, see Figure 1) totaling approximately 146,154 km2.
AOM AREA-2 has commissioned WYCO Mineral Advisors (WYCO) to produce a Technical Report Summary (TRS) focused on the Mineral Resources in Area 2 (Dorado). The Assessment is based on historical data and is preliminary in nature, and results in only Inferred Mineral Resources.
B. Property Description and Ownership
Four consortia of offshore development companies demonstrated the technical feasibility of collecting, lifting, and converting nodules into metals in the 1970s, but development of the industry was frustrated by the absence of regulation and a governing body. In 1994, the United Nations (UN) established the International Seabed Authority (ISA) pursuant to the UN Convention on the Law of the Sea (UNCLOS). The ISA governs the development of seabed resources for UNCLOS member states in the territories beyond the Exclusive Economic Zones (EEZ) governed by coastal states.
At the time of this report, the ISA is yet to finalize the Mining Code, including Regulations on the Exploitation of Mineral Resources in the Area as required under UNCLOS.
In 1980, the Unites States of America (U.S) enacted the Deep Seabed Hard Mineral Resources Act (DSHMRA) 30 U.S.C. §1401 et seq.) authorizing the National Oceanic and Atmospheric Administration (NOAA) to issue licenses for exploration and permits for commercial recovery from the deep seabed. These activities are limited to areas beyond national jurisdiction and are intended to ensure that U.S. entities can participate in seabed mining despite the US not being a party to the UNCLOS or the 1994 Implementation Agreement.
AOM is in the process of applying for a license covering two areas directly under the U.S. regulatory regime governed by DSHMRA. It is important to note the license has not been approved by DSHMRA and is not under an exploration contract issued by the ISA. Subject to regulatory review and approval, AOM anticipates that any future commercial recovery activities would be conducted pursuant to a permit issued by National Oceanic and Atmospheric Administration (NOAA) under the U.S. legal regime.
|
|
AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 5 |
These applications will have to undergo review and commencement of Commercial Recovery is subject to approval of these licenses under DSHMRA. At the time of writing this report, AOM does not hold any exploration licenses or commercial recovery permits under the DSHMRA framework.
Any reference to activities proposed to be conducted by AOM is inherently uncertain and should be considered forward-looking in nature. No assurance can be given that any permit under DSHMRA will be issued, or that if issued, such permit will contain terms and conditions commercially or operationally viable for the project considered in this assessment.
The proposed license area consists of two non-contiguous Subareas (Subareas North and South, together named “Area 2”, see Figure 1) in the Southern Pacific Ocean, totaling approximately 146,154 km2.

C. Geology and Resource Estimate
The formation and distribution of polymetallic nodules in Area 2 are primarily controlled by water depth, latitude, and seafloor sediment type. Geological domains identified include volcanic outcrops, volcanic highs, sediment drifts, and high-slope (>10°) areas, which were excluded from resource estimates.
Exploration data underpinning the Mineral Resource estimates comprise historical sampling mostly by Japanese scientists using free-fall grab samplers (FFG) and box core (BC) samplers. Nodule abundance is reported on a wet basis with an assumed moisture content of 30% Mineral Resource estimation is based on the extensive reports published by these Japanese scientists. The Mineral Resource classification follows SEC Regulation S-K (subpart 1300), with limited data density and modifying factors resulting in Mineral Resource Estimation. No abundance values are available for Area 2 South, making it impossible to estimate the extent and tonnage of ore in this area. Excluding areas with a greater than 10° slope and using a cutoff grade of 6% kilograms of nodules per square meter, Inferred resources for Area 2 North are shown in Table 2able 2.

H. Economic Analysis
The project is not at a stage where Economic Analysis would be appropriate
I. Permitting Requirements
To obtain an exploration license, NOAA must have a complete administrative record showing that the applicant is eligible and that the proposed exploration plan is environmentally and operationally responsible. Although the exact required “shape” of the submittal depends on NOAA’s implementing text, the substantive elements NOAA expects (and has historically required) include: the applicant’s eligibility and corporate structure; delineation of the requested license area; the detailed exploration plan of work and schedule; the technical capability to conduct exploration and any test mining; the environmental baseline and monitoring plan for exploration activities; safety and pollution prevention controls; and evidence of financial responsibility.
J. Qualified Person’s Conclusions and Recommendations
It is the QP’s opinion that the Mineral Resources Estimate derived from the published data is representative of the informing data, and that the data is of sufficient quality to support a Mineral Resource Estimate for Area 2 at an Inferred confidence level. It is important to understand that the “inferred” designation for a mineral resource is fundamentally a guide to help set priorities for subsequent, more detailed exploration work that will be necessary to precede commercial recovery of the resource.
The QP notes that the resources estimate is based on historic work by different parties that may or may not have had various sampling and Quality Assurance/Quality Control (QA/QC) programs which adds a degree of uncertainty with all the samples. However, the work was performed by well-established oceanographic researchers that would have been expected to be competent in sampling and analysis. Future sampling programs to be carried out by AOM will include a robust QA/QC program.

B. Terms of Reference and Purpose
The effective date of this TRS report is February 12, 2026. It is the Qualified Person’s opinion that there are no known material changes after this date. This TRS uses US English spelling and a combination of Metric and Imperial units of measure. Ore grades are presented in dry weight percent (wt.%), while ore quantities are stated in metric tons (tonnes) or millions of tonnes. Except where noted, geographic coordinates in this TRS are presented in metric units using the World Geodetic System (WGS) 1984. All seafloor areas listed are geodesic areas. The purpose of this TRS is to report on Mineral Resources for AOM’s Area 2 Project Area.
C. Sources of Information
The Japanese Government conducted seabed mineral exploration in the South Pacific. Implementation and execution of the survey were consigned to JICA in cooperation with the Metal Mining Agency of Japan (MMAJ). JICA conducted three expeditions to the Project area using the RV Hakurei Maru No. 2 in 1986, 1990 and 2000 (JICA-MMAJ, 2001). The methods used for collection and analysis of these samples are described below.
Seafloor bathymetry was downloaded from the GEBCO 2025 map and seafloor slopes were derived from this map using GIS tools.1
D. Personal Inspection Summary
Personal Inspection was not possible as deposits are thousands of meters below sea level. However, the QPs for this report have been involved in similar exploration sampling programs for Manganese Nodules in the CCZ.
Dr. Morgan worked for ten years on the Lockheed Ocean Mineral exploration project from 1975 to 1984, including participation in several sampling cruises that recovered thousands of polymetallic nodule samples and several tonnes of nodules for ore assays and metallurgical testing. No direct observation of the deep seafloor was involved.
Mr. Wyatt has participated in several exploration sampling cruises that recovered nodules for analysis as well photographic, geophysical, and biologic data. No direct observation of the deep seafloor was involved.

B. Mineral Rights
AOM Area-2 LLC (whose parent company is American Ocean Minerals Corporation), under United States sponsorship, seeks the issuance of an exploration license from the National Oceanic and Atmospheric Administration (NOAA), pursuant to the Deep Seabed Hard Mineral Resources Act (DSHMRA), in accordance with the regulations at 15 CFR Part 970. AOM as of the date of this report does not have a license.
C. Description of Property Rights
Area 2 is on the seafloor outside of any national jurisdiction. President Donald Trump signed Executive Order 14285, “Unleashing America’s Offshore Critical Minerals and Resources,” on April 24, 2025, aiming to fast-track U.S. deep seabed mining for critical minerals (e.g., cobalt, nickel, rare earths) in federal waters and promote development in international waters, leveraging the 1980 Deep Seabed Hard Mineral Resources Act (DSHMRA) and establishing the U.S. as a leader. The order directs agencies like NOAA to streamline permits, establishing a new regime for seabed mining.
D. Royalties and Taxes
Under DSHMRA, royalties and taxes payable on any future commercial recovery of polymetallic nodules by U.S. entities in areas beyond national jurisdiction are governed by domestic U.S. law rather than international frameworks such as the ISA, to which the U.S. is not a party. DSHMRA does not prescribe specific royalty rates, it authorizes NOAA to issue exploration licenses and commercial recovery permits, with terms and conditions that may include financial obligations. These obligations are determined on a case-by-case basis during the permitting process and are designed to ensure that U.S. seabed mining activities are conducted responsibly and in alignment with national interests.
NOAA’s regulatory framework under DSHMRA includes provisions for public comment and environmental review but does not currently mandate a fixed royalty or taxation regime akin to ISA’s proposed ad valorem models. As such, financial terms are negotiated individually and may evolve with future legislative or executive directives, such as the April 2025 Executive Order promoting U.S. leadership in seabed mineral recovery.

| Minimum (shallowest) | –2,704 | 0 | ||||||||
B. Access to Property
Area 2 is located outside of any national jurisdiction. It is most easily accessible by ship from various ports in the American Samoa, New Zealand, and Australia. As the deposit does not include any habitable land and is not near coastal waters, all personnel and material are expected to be transported to the project area by ship. Exploration work is being planned to use modern oceanographic survey and sampling techniques.
C. Availability of Required Infrastructure
There are multiple vessels and equipment available to perform exploration and sampling activities. Additional infrastructure to harvest and process nodules will be dependent on regulations and future work requirements. It is expected that some infrastructure that currently exists can be used or repurposed. Additionally, multiple companies and governments are in the process of developing infrastructure that may be utilized in the future.

V. HISTORY
The first cruise programs dedicated to investigating nodules in the Cook Islands and adjacent regions were mounted in the mid-1970s by the New Zealand Oceanographic Institute. As a precursor to this, the Institute compiled all available data from Challenger and Eltanin cruises completed elsewhere in the region into maps of the nodule properties, including their Mn, Fe, Ni, Co, and Cu contents, and their distribution (Glasby et al., 1974). Further cruises were undertaken in the late 1970s, targeting polymetallic nodules in the South Penrhyn Basin and Aitutaki Passage. Between 1976 and 1981, the Committee for Coordination of Joint Prospecting for Minerals Resources in South Pacific Offshore Areas (CCOP/SOPAC) carried out several cruises in the Cook Islands region. During these cruises, nodules were collected, and the results of their analyses served to define areas of potential economic interest to be surveyed in more detail by later cruises under the Japan-SOPAC Cooperative Study on Deep Sea Mineral Resources in the South Pacific (Cronan, 2013) .
Extensive cruises were carried out in the region by the Japan International Cooperation Agency (JICA) between 1986 and 2000. JICA conducted three expeditions to the Project area using the RV Hakurei Maru No. 2 in 1986, 1990 and 2000. Samples were collected by freefall grab (FFG), box core (BC), long core (LC) and armed dredge (AD) tools. Survey stations were placed based on datum lines every 1° (111 km) in latitude and longitude Infill sites were placed on a 39.3-km (21.5-mi) grid. Three samples (FFG or BC) were collected at each survey station in the form of an inverted triangle. The base sampling point of each station was set at the southern apex of the triangle, and the two other samples were collected at the remaining apexes of the triangle. Sampling points were ~2.6 km (~1.4 mi) apart. Sampling was conducted in a clockwise direction.
VI. GEOLOGICAL SETTING, MINERALIZATION, AND DEPOSIT
A. Global Distribution
Polymetallic nodules with various grades of base metals are found in submarine settings worldwide (Monget, 2015). This widespread distribution was recognized by the early 1970s when Kennecott Exploration surveyed all the major ocean basins. Nodules form at a wide range of depths, from 4,000–6,000 m below sea level in the mid Pacific to 200 m below sea level in the Gulf of Bothnia (Boström et al., 1982) and 30 m in the Baltic Sea (Anufriev and Boltenkov, 2007). The location of nodule formation is reflected in nodule chemistry. Nodules with relatively high Co grades are found within the Cook Islands region, often accompanied by high nodule abundances.

B. Local Geology
The Cook Islands include some of the oldest (90–124 Ma) known oceanic seafloor (Müller et al., 2016), compared to a global average oceanic crust age of 64 Ma (Seton et al., 2012). To the northwest, the Manihiki Plateau is dated ~123–124 Ma (Taylor, 2006; Timm et al., 2011) and might be part of a much larger submarine large igneous province that rifted apart shortly after its formation. The plateau has boundary faults and horsts on its northern and eastern sides as well as internal and broadly sub-parallel rift zones (Winterer et al., 1974). Dating of the region is compromised by a lack of detailed seabed magnetic data. Much of the formation formed during the Cretaceous long normal period (124.6–84 Ma).
Volcanic edifices are superimposed onto the seabed geology and include isolated chains of seamounts and knolls as well as more continuous volcanic rises. The chains are in a variety of orientations, but predominantly west-northwest trending and some are interpreted to have resulted from hotspot activity (Wessel and Kroenke, 2008; Jackson et al., 2020). Knolls and seamounts are found on the plateau as well as the abyssal plain, not least in the western Manihiki Plateau.
C. Sediments
Red clay is the dominant sediment in abyssal basins of the South Pacific (Glasby, 1976), described as predominantly zeolite-rich and red-brown pelagic clay, with biogenic silica and carbon increasing with decreasing latitude and at depths above 4,800 m (Heine et al., 2015).
Fine pelagic sediments described as red or brown clay are the predominant sediment type in Area 2. Deposition began during the pre-late Miocene, with the surface sediment likely to be deposited within the last 500 kyr (JICA-MMAJ, 2001). Sub-bottom profiling indicates that abyssal plains are covered by unconsolidated sediments, ≤20 m thick, and rarely exceed 40 m (JICA-MMAJ, 2001).
D. Ocean Currents
Two major oceanic currents supplying well-oxidized bottom water are thought to influence mineralization in the Cook Islands EEZ (Glasby et al., 1986). The westward-flowing Southern Equatorial Current system (Figure 4) is derived from a divergence along the equator that leads to the upwelling of nutrient-rich waters, stimulating high biological productivity. The current system is the northern limb of an anticlockwise-circulating gyre within which the Cook Islands EEZ sits. Biological productivity in the southern part of the Cook Islands EEZ is low (Lutz et al., 2007; Cronan, 2013).
The Antarctic Bottom Water, which flows between the seafloor and ~3,500 m, has been inferred to flow to the northeast along the Aitutaki Passage (Usui, 1983), along the ridge immediately south of the Nova-Canton Trough (Yamazaki, 1992), and around the northeastern margin of the Manihiki Plateau to enter the North Penrhyn Basin. The formation of polymetallic nodules has been attributed to increased flow of the Antarctic Bottom Water during the Paleogene or Cretaceous (Usui, 1994).

E. Local and Property Geology
Local geology needs to be determined during the first phases of the exploration using the exploration surveying and sampling techniques described below.
1. Mineralization
The mineralization occurs at the water-sediment interface on the seafloor, in the form of polymetallic nodules that are significantly enriched in Co, Ni, and Cu. Locally, a minority component of the nodules occurs within the sediment, up to 30 cm depth. Polymetallic nodules are ubiquitous on the abyssal plains surrounding the Cook Islands, mostly at depths between 4,800 and 5,200 m (Kenex, 2014), in the shape of nodules fields that are continuous on a scale of tens of kilometers, essentially forming 2D deposits that trace the sediment-water interface.
The continuity of the mineralization on a regional scale (10s of km) is one of the main characteristics of this deposit type and a direct result of the factors controlling the mineralization also operating a regional scale. Within areas that are conducive to nodule formation, smaller-scale (several 100s of m) features can be present (e.g. knolls, escarpments, sub-circular depression and grooves) that prevent or negatively influence nodule formation. In general, within the abyssal plains, the areal extent of these smaller-scale features tends to be marginal compared to the areal extent of the nodule field. Because the thickness of the mineralized layer (up to several decimeters) is five orders of magnitude less than the lateral extent of the nodule fields (several 10s of km), no meaningful cross sections can be drafted.
The nodules within rea 2 are dark brown to black and measure up to ~20 cm along their long axis. Nodule shape and size are highly variable across the Project area, ranging from centimeter-sized, irregularly shaped pellets to decimeter-sized spheres and plates. The nodules exhibit concentric layering, with the nucleus often being a ‘foreign’ object (e.g. a shark’s tooth or a piece of pumice).
2. Deposit Type
Polymetallic nodules are hydrogenetic and diagenetic concretions of manganese and ferromanganese oxides with high levels of minor, adsorbed elements, including Co, Ni, Cu, Zn, Ti and other metals.
|
|
AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 19 |
Nodules with a relatively high Co grade (>0.26% Co) are found in the central Cook Islands (including the Project area). The higher grades are likely due to a high proportion of hydrogenetic growth, promoting the relative accumulation of Co ions in the oxic vernadite crystal structure (Fe is >13%) and a highly oxygenated bottom water mass (assumed to be the Antarctic Bottom Water). Similar controls on mineralization are described for ferromanganese crusts on seamounts and guyots where Co grades are typically >0.5% and have reported >1% Co (Hein and Morgan, 1999; Hein and Koschinsky, 2014).
In the northeastern Cook Islands, higher Ni and Cu grades are associated with higher primary productivity (surface plankton). Net export of this may have also helped lead to suboxic conditions and higher Ni and Mn grades, similar to those described in the CCZ (Lipton et al., 2016).
VII. EXPLORATION
Polymetallic nodule deposits are fundamentally two-dimensional; the nodules lie on the surface of or partially buried within fine-grained surficial sediments. No drilling is necessary for exploration or subsequent commercial recovery.
A. Exploration Work
Most of the samples were collected during the JICA program using free fall grab (FFG) samplers. The principal components of FFG samplers are a pair of spring-loaded clamshell net bags for collecting the sample, an air-filled sphere to create buoyancy and containers filled with ballast.
The operation of an FFG sampler is shown schematically in Figure 4. The FFG sampler is released, untethered, over the side of the exploration ship and sinks to the seafloor under the weight of the ballast. When the FFG sampler makes contact with the seafloor ejection of the ballast is triggered which makes the sampler buoyant. As the sampler begins to rise, the clamshell net bags close, capturing the nodules at the land-out point. After it reaches the sea-surface, the FFG sampler is recovered by the boat. FFG samplers are quicker, easier and cheaper to operate for mineral resource samples than box corers (used for biological, geotechnical, mineral and other types of sampling) and so were preferred by the early exploration programs.

Figure 5 shows the standard layout for use in collecting the FFG samples in the JICA program. Sample locations were collected by different satellite systems for each expedition, with accuracy improving with each survey. Sample locations were determined by the ship’s location during deployment. It is noted that sampling equipment can drift (including tethered sampling methods). Sample location precision is estimated to be in the order of 100–500 m against a sample spacing of ~25 km.

B. Terrain-based Domains
Polymetallic nodule deposits of commercial interest occur on sediment-covered abyssal plains that constitute the vast majority of the Cook Islands deep seafloor. An important aspect of potential future exploration work will be the analysis of the relatively high resolution (compared to GEBCO) bathymetry collected by MBES surveying to distinguish the different components that make up the abyssal plains within Area 2 and to remove from consideration the other facies (e.g. ridges, calderas and other hard substrate or steep slope seafloor) that will not host commercially interesting nodule deposits.
C. Anticipated Exploration Methods
AOM possesses access to exploration equipment. The selection and configuration of this equipment have been undertaken with the intent that ensures that it is not only operationally capable of supporting the full range of planned geophysical, geochemical, and biological investigations within the proposed license areas, but also methodologically aligned with the expectations of U.S. regulators and the international community.
AOM anticipates its exploration and sampling will provide continuity and comparability with legacy U.S. and international datasets. Particular emphasis has been placed on the foundational work of the NOAA Deep Ocean Mining Environmental Study, which established the first systematic environmental baselines for U.S. exploration areas in the CCZ. The equipment and protocols selected by AOM are directly aligned with those earlier methods wherever possible, thereby ensuring that new data can be analyzed within the same interpretive frameworks and contribute to a coherent long-term record of environmental conditions and resource potential.
AOM aims to ensure that its equipment standards are consistent with contemporary international recommendations. AOM guarantees that all data generated will be directly comparable to results submitted by other contemporary explorers for this deep seabed resource, and therefore suitable for integration into shared environmental databases and regional environmental management plans.
The AOM exploration planned toolkit reflects advancements described in recent peer-reviewed literature, particularly in relation to high-resolution multibeam bathymetry (ship-based and from autonomous underwater vehicles), box coring, benthic imaging, and water-column monitoring. By integrating these improvements, AOM anticipates that the proposed exploration program does not merely replicate past efforts but enhances them.

VIII. SAMPLE PREPARATION, ANALYSIS, AND SECURITY
During the 1986 and 1990 cruises, the samples were assayed by X-ray fluorescence (XRF) onboard the vessel for Cu, Co, Fe, Mn, and Ni. Samples collected during the 2000 cruise were analyzed at ALS Chemex, Canada, by inductively coupled plasma emission spectroscopy for Cu, Co, Fe, Mn, Ni, Ti, Si, Al, Ca, Na, K, and P. JICA expeditions were also equipped with deep-sea cameras that collected a photograph of the mineralized seabed prior to a sample being collected.
Documentation of sample preparation and security was not available for review. Based on the quality reputation of the labs and the organizations doing the sampling It is believed that the procedures would have been reasonable and resulting data suitable for use in mineral estimation, albeit a lower confidence level than if documentation were available.
IX. DATA VERIFICATION
A. Mineral Resources
1. Exploration Data Compilation and Validation
Most of the data were obtained from analysis of free-fall grab sampler recoveries, although a few results from box core recoveries are also included. Abundance (weight of nodules per unit area on the seafloor, (usually with units kg/m2) is estimated simply by dividing the weight of recovered nodules by the surface area covered by the open jaws of the sampler (~0.25 -0.5 m2 coverage). As discussed in Hennigar, Dick and Foell (1986), free-fall grab samplers are the best tools available for the first order assessment of nodule abundance, but they consistently underestimate the actual abundance. No adjustments have been made to the samples or the mineral resource estimation.
Metal content in the samples collected was determined by a variety of methods, including atomic absorption and X-ray fluorescence. During the 1970s and 1980s, the U.S. Bureau of Mines distributed standard nodule samples (labeled “A-1” and “P-1”) that had been extensively analyzed by the Bureau and then mixed into a uniform powder.
These standard samples were later transferred to the U.S. Geological Survey after the Bureau closed in 1996. JICA scientists obtained sub-samples of these standards to evaluate the accuracy of their methods. No results of these standard tests are available; however, the scientists responsible for the analysis protocols were able to use state-of-the-art methods to ensure that their results were as accurate as possible.

2. Limitations on and Adequacy of Data Verification
Since the other programs were carried out by highly professional private and government scientists, such data used in the resource is deemed adequate for an Inferred Mineral Resources estimate.
X. MINERAL PROCESSING AND METALLURGICAL TESTING
A. Candidate processing methods
This project is not at a stage where a candidate processing method can be determined.
XI. MINERAL RESOURCE ESTIMATE
A. Key Assumptions, Parameters, and Methods
The AOM Area 2 Mineral Resource estimate includes estimation of nodule wet tonnage and the Mn, Fe, Co, Ni and Cu dry weight percentages within the polymetallic nodule deposits that occur in Area 2. The only modifying factors included are the elimination of seafloor areas with slopes greater than 10° and a cutoff abundance value of 6 kg/m2 below which the samples were not used in the resource estimation. Further exploration with MBES and near-seafloor surveying will be required to identify additional areas where obstacles to mining are smaller than the regional GEBCO maps reveal.
1. Methods
To develop preliminary resource estimates, AOM applied Empirical Bayesian Kriging (EBK), a geostatistical interpolation method suited for sparse but spatially structured datasets. Empirical Bayesian kriging (EBK) is a geostatistical interpolation method that automates the most difficult aspects of building a valid kriging model. Other kriging methods in Geostatistical Analyst require you to manually adjust parameters to receive accurate results, but EBK automatically calculates these parameters through a process of sub-setting and simulations.
Empirical Bayesian kriging also differs from other kriging methods by accounting for the error introduced by estimating the underlying semivariogram. Other kriging methods calculate the semivariogram from known data locations and use this single semivariogram to make predictions at unknown locations; this process implicitly assumes that the estimated semivariogram is the true semivariogram for the interpolation region. By not taking the uncertainty of semivariogram estimation into account, other kriging methods underestimate the standard errors of prediction.

AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 24 |
2. Subareas and Block Delineations
EBK was used to generate continuous surfaces of polymetallic nodule abundance (wet weight, kg m-2) and dry-weight metal content for manganese (Mn), cobalt (Co), nickel (Ni), and copper (Cu). A fishnet grid with 500 m spacing between points was inserted into the area, and abundance and metal contents were extracted.
B. Basis for Establishing the Prospects of Economic Extraction of Mineral Resources
Based on a range of metal prices for the metals contained in the nodules a cutoff grade of 6 kilograms of nodules per square meter (6kg/m2) was chosen as basis for economic extraction.
C. Mineral Resource Classification
Under S-K 1300 to reflect geological confidence, Mineral Resources are subdivided into the following categories based on increased geological confidence: Inferred, Indicated, and Measured, which are defined under S-K 1300 as:
Inferred Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated based on 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 additional modifying factors not quantified in this TRS 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 directly converted to a mineral reserve.
Indicated Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated based on adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.
Measured Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated based on conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 25 |
Based on the uncertainty of the QA/QC measures and analytical accuracies associated with the archival abundance and metal content available for this TRS, and the lack of sample density only Inferred Mineral Resources may be defined.
D. Assumptions for Multiple Commodity Mineral Resource Estimate
No metal/mineral equivalents are being used or reported.
E. Mineral Resource Uncertainty Discussion
Mineral Resources are not Mineral Reserves and do not necessarily demonstrate economic viability. There is no certainty that all or any part of this Mineral Resource will be converted into Mineral Reserve.
Inferred Mineral Resources are too speculative geologically to have economic considerations applied to them to enable them to be categorized as mineral reserves.
Mineral Resource estimates may be materially affected by the quality of data, natural geological variability of mineralization and / or metallurgical recovery and the accuracy of the economic assumptions supporting reasonable prospects for economic extraction including metal prices, and mining and processing costs.
The quality of some of the data could not be independently verified. This does not necessarily mean that the data is inaccurate, however, it does increase the level of uncertainty regarding the quality of the data.
The following risks were identified:
| | Sample coverage is limited. |
| | Uncertainty around QA/QC programs in place for the historic sampling programs. |
| | Original records of the sample collections and survey measurements are not available. |
| | Secured and signed certificates were not available for analytical measurements. |
Additional sampling and exploration to address the aforementioned points, will allow the evaluation and possible recategorization of part of the Mineral Resources from Inferred to Indicated.
|
|
AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 26 |
Mineral Resources may also be affected by the estimation methodology and parameters and assumptions used in the grade estimation process including top-cutting (capping) of data or search and estimation strategies although it is the QP’s opinion that there is a low likelihood of this having a material impact on the Mineral Resource estimate.
Table 6 shows Mineral Resource estimate based on the above-described sources, assumptions, and methods. It is not possible to estimate the extent and tonnage in Area 2 South because no abundance estimates are available. Nodule abundance estimates are customarily listed as “wet” because the minerals are very hygroscopic and the samples are usually weighed soon after recovery at sea. In practice, the nodules lose about 6% of their weight within a few days or weeks, depending on whether they are in sealed sample containers, the temperature, and ambient humidity. The normal conversion to determine tonnage estimates is to multiply the wet weight by 0.7, which is the average weight difference after the nodules have been pulped and dried at 110°C for a few hours.

F. Qualified Person’s Opinion on Factors that are Likely to Influence the Prospect of Economic Extraction
It is the QP’s opinion that the Mineral Resource Estimate is representative of the informing data and that the data are of sufficient quality to support this Mineral Resource Estimate to an Inferred confidence level.
Future Mineral Resource Estimates may be materially impacted from changes in geological knowledge as a result of new exploration data.

|
AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 29 |
| | Geological interpretation and estimating methodology is appropriate for the style of mineralization and data available to AOM. |
| | The lack of documented QA/QC programs limit the confidence of the estimation results and that have been considered during the classification of the mineral resources resulting in an Inferred Mineral Resource. |
The Inferred Resource category assigned to the Mineral Resource estimate reflects the confidence of the estimate as described above. Inferred resources have a high level of geological uncertainty and therefore cannot support the use of additional modifying factors required to convert Mineral Resources into Mineral Reserves.
XXIII. RECOMMENDATIONS REGARDING MINERAL RESOURCES
| | Secure exploration license for Area 2. |
| | Plan and execute an exploration program. The program should aim to: |
| | Construct updated procedures that describe in sufficient detail the activities of capture, administration, and backup of current and future data. |
| | Improve the local geological knowledge of the deposit to better understand the geological controls on mineralization and include them in future updates of the geological models. This information should be included in future updates of the geological model as well as in grade estimation. |
| | Meet requirements of DHSRMA |
| | Refine the geological model should by interpreting the local lithological units. |
| | Design and implement a samples (pulps) reanalysis campaign with an appropriate QA/QC program, and based on the results obtained, |
| | Maintain an in-situ deposit and recovered sample photo library for all sampling campaigns going forward. |
| | Maintain original and/or digitized records of all survey and sample data in a secure database. |
| | Analysis and testing of samples should be completed by a reputable, and preferably ISO-accredited laboratory, qualified for the element or material to be analyzed or tested. All analytical or other test results should be supported by duly signed certificates or reports issued by the laboratory or testing facility and should be accompanied by a statement of the methods used. |
| | Conduct replicate sampling at representative stations to confirm the existing nugget variability. |
|
|
AOM AREA-2 S-K 1300 TECHNICAL REPORT SUMMARY FEBRUARY 12, 2026 | 30 |
