Analysis

On Jan 26, the day this news came out, the stock closed 23.9% below the previous close. A negative reaction despite today’s strong metallurgical and grade results would have contrasted with the objectively high recoveries and near-surface mineralization highlighted, such as 97.0% MREE extraction and surface TREO up to 28,870 ppm. Historically, financing and listing news triggered sharp moves, including a -28.16% reaction to an upsized offering. Any sustained weakness around technical milestones could reflect market focus on execution, capital needs, or prior dilution rather than the project data itself.

metallurgical recoveries technical

"pleased to announce high metallurgical recoveries from initial testwork"

Metallurgical recoveries are the percentage of a target metal that is successfully extracted from mined ore during processing and ends up in the final concentrate or product. Higher recoveries mean more saleable metal from the same amount of ore — like squeezing more juice from the same fruit — so they directly affect a mine’s revenue, unit costs and profitability, and are a key metric investors use to judge a project’s economic strength.

rare earths elements technical

"for extracting rare earths elements ("REE") into leach solution"

Rare earth elements are a group of 17 metallic minerals used in tiny amounts inside many modern technologies—like magnets in wind turbines, batteries, smartphones, and electric motors—so they act like specialized spices in a recipe that make high-tech products work. Investors track them because supply is limited and concentrated in a few places, so shifts in mining, trade or regulation can quickly change costs, company margins and industry growth prospects.

titanium dioxide technical

"97% of the titanium dioxide (TiO₂) reported to the leach residue"

A fine, white inorganic powder used as the main pigment to make paints, coatings, plastics, paper, cosmetics and sunscreens look bright and opaque — think of it as the “flour” that gives products their color and hiding power. Investors watch titanium dioxide because it is a widely used commodity chemical whose price and availability track construction, automotive and consumer demand, and because production and health or environmental rules can create supply disruptions and regulatory risk that affect company profits.

nitric acid technical

"Two sighter leach tests using nitric acid (HNO₃) were completed"

A strong, corrosive chemical (HNO3) used to make fertilizers, explosives, dyes and many industrial chemicals; think of it as a staple ingredient in large-scale manufacturing similar to how flour is essential for baking. It matters to investors because its price, availability and safety rules affect costs, production capacity and regulatory risk for chemical, fertilizer and mining companies, so shifts in supply or regulation can change profit margins and project timelines.

ppm technical

"12m @ 5,961 ppm Total Rare Earths Oxides (TREO)"

Parts per million (ppm) is a unit that expresses how many units of a substance exist in one million units of a mixture or material — imagine one drop of dye spread through an Olympic-sized pool to picture a very small concentration. Investors watch ppm readings because regulatory limits, product contamination, pollutant emissions or chemical residues often use this scale; small numeric changes can mean compliance problems, remediation costs, production shutdowns or reputational risk that affect a company’s value.

total rare earths oxides technical

"5,961 ppm Total Rare Earths Oxides (TREO)"

Total rare earths oxides (TREO) is the combined amount of the chemical oxides of all rare earth elements in a rock, ore or product, reported as a single percentage or weight. Think of it like the total sugar content listed for a fruit mix: higher TREO means more of the valuable ingredients are present and easier to extract. Investors use TREO to compare resource quality, estimate processing costs and predict how profitable or strategically important a deposit or supplier will be for technologies that rely on rare earths.

magnetic rare earths oxides technical

"1,690 ppm Magnetic Rare Earths Oxides (MREO)"

Magnetic rare earths oxides are chemical compounds made from rare earth elements (like neodymium, samarium or dysprosium) combined with oxygen that form the magnetic ingredients used in powerful permanent magnets. Think of them as the concentrated metal “recipe” that gives small magnets the strength to turn electric motors or store data; their supply, cost and availability matter to investors because they affect production costs, technology adoption and geopolitical supply risks across industries such as EVs, wind power and electronics.

regulation s-k regulatory

"Qualified Person under Item 1300 of Regulation S-K from Altilium Group"

A set of U.S. Securities and Exchange Commission rules that tell public companies which narrative and qualitative details must be disclosed in filings, such as risk factors, management discussion, executive pay, legal proceedings and business description. Think of it as a standardized checklist or blueprint that ensures investors get the same types of background information from every company so they can compare risks, management quality and strategy before making investment decisions.

Initial Tests Achieve Up To 97% Recovery for Magnetic Rare Earths Elements

Belo Horizonte, Brazil--(Newsfile Corp. - January 26, 2026) - Atlas Critical Minerals Corporation (NASDAQ: ATCX) ("Atlas Critical Minerals" or "Company"), a company focused on critical minerals for energy, technology, and defense applications, is pleased to announce high metallurgical recoveries from initial testwork on samples from its 100%-owned Alto do Paranaíba Project ("Project") in Minas Gerais state, Brazil. The testwork was conducted to evaluate the effectiveness of the Altilium Ti/REE Process™ (pat. pend.) for extracting rare earths elements ("REE") into leach solution and upgrading titanium ("Ti") into leach residue. Testing was directed by a Qualified Person under Item 1300 of Regulation S-K from Altilium Group Limited. Results demonstrated exceptional REE extraction rates, indicating strong potential amenability for commercial processing.

• Outstanding Rare Earths Extraction: Leaching achieved 97.0% extraction for Magnetic Rare Earths Elements (MREE), 95.2% for Light Rare Earths Elements (LREE), 93.8% for Total Rare Earths Elements plus Yttrium (TREY), and 83.9% for Heavy Rare Earths Elements (HREE);

• Titanium Concentration Upgrade: 97% of the titanium dioxide (TiO₂) reported to the leach residue, concentrating from 13.4% to 26.0%, indicating potential for titanium by-product enrichment; and

• Amenable Mineralization: The Project's mineralization responded strongly to leaching, supporting the potential feasibility of processing the Project's ores for commercial rare earths recovery with titanium recovery as a byproduct.

Metallurgical Extraction Results

A 50 kg composite, considered representative of the mineralization of the Project's Block 1 properties, was processed at the Lakefield, Canada, analytical laboratory of SGS Canada Inc. ("SGS"), a premier mineral evaluation company. Head samples were air-dried, milled to 100% passing 0.5 mm, and subjected to chemical and mineralogical characterization. Two sighter leach tests using nitric acid (HNO₃) were completed:

• Leach 1: Direct acid leach on the as-milled sample.
• Leach 2: Thermal pre-treatment (roasting) followed by acid leach.

Element suites assayed included Al, Ca, Co, Cr, Fe, Ga, Mg, Mn, Ni, S, Sc, Si, Ti, and rare earths elements.

The following table summarizes the rare earths extraction rates achieved:

TEST	TREY (%)	LREE (%)	MREE (%)	HREE (%)
Leach 1 (Direct)	57.7	57.1	62.1	63.4
Leach 2 (Roasted)	93.8	95.2	97.0	83.9

 

As observed from the table. Leach 2 delivered near-complete extraction of magnetic rare earths elements and strong recoveries across all rare earths groupings.

"These highly encouraging metallurgical results represent a significant step forward for our Alto do Paranaíba Project," stated Marc Fogassa, Chairman and CEO of Atlas Critical Minerals. "Achieving 97% extraction of magnetic rare earths elements is an important milestone. We believe our results to date indicate that the mineralization is amenable to processing, a key factor for the Project's economic potential."

Initial Drilling Campaign Results

An initial auger drilling program across several Project areas comprised 13 holes totaling 144 meters. A total of 178 samples were analyzed, including approximately 22% QA/QC control samples. Drilling intercepted near-surface, high-grade mineralization, including the following highlights:
