Atlas Critical Minerals Corp. (ATCX; NASDAQ) announced high metallurgical recoveries from initial testwork at its 100%-owned Alto do Paranaíba Project in Minas Gerais, Brazil. The work evaluated the Altilium Ti/REE Process for extracting rare earth elements into leach solution and upgrading titanium into leach residue. Testing was directed by a Qualified Person under Item 1300 of Regulation S-K from Altilium Group Limited.
According to the company, the testwork demonstrated rare earth element (REE) extraction rates of 97.0% for magnetic REEs (MREE), 95.2% for light REEs (LREE), 93.8% for total REEs plus yttrium (TREY), and 83.9% for heavy REEs (HREE). Additionally, titanium dioxide was concentrated from 13.4% to 26.0% in the leach residue, with 97% of TiO₂ reporting to residue.
A 50 kg composite sample, described as representative of the Project's Block 1 properties, was processed at SGS Canada Inc. in Lakefield. Two leach tests were conducted: one with direct acid leaching and one with thermal pre-treatment followed by leaching. The latter yielded the highest recovery rates, including the 97.0% MREE extraction.
"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, in the news release. "Achieving 97% extraction of magnetic rare earth 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," he said in a company news release.
An initial auger drill campaign comprising 13 holes totaling 144 meters intercepted near-surface, high-grade mineralization. Highlights included 12 meters grading 5,961 ppm total rare earth oxides (TREO) in hole DHTI-001 and 6 meters grading 7,729 ppm TREO in hole DHTI-002. Titanium dioxide grades in these intercepts ranged from 11.2% to 15.9%.
Surface sampling across the project area yielded grades up to 28,870 ppm TREO and 7,493 ppm magnetic REOs. Titanium dioxide values from surface samples reached as high as 23.2%.
Multi-Phase Work Program Advancing at Alto do Paranaíba
Atlas Critical Minerals reported several technical milestones across its Alto do Paranaíba Project that support ongoing project advancement. The company completed metallurgical testing on a 50 kg composite sample from Block 1, conducting two nitric acid leach trials that showed significantly higher extraction rates with thermal pre-treatment.
The initial auger drilling campaign spanned 13 holes totaling 144 meters and generated 178 samples, including 22% QA/QC control samples. Drilling intersected high-grade, near-surface mineralization across multiple areas. Notable intervals included 12 meters grading 5,961 ppm TREO and 6 meters grading 7,729 ppm TREO, accompanied by magnetic REO and titanium dioxide values.
Streetwise Ownership Overview*
Atlas Critical Minerals Corp. (ATCX;NASDAQ)
Atlas's January 2026 investor presentation also reported comprehensive surface sampling results. Samples from the project area showed consistently high TREO grades, with values up to 28,870 ppm. These results, combined with titanium dioxide levels reaching 23.2%, contribute to ongoing geological modeling and resource evaluation efforts at the site.
Further evaluation of the Altilium Ti/REE Process incorporated both chemical and mineralogical characterization, targeting elements such as aluminum, calcium, cobalt, iron, titanium, and various rare earths. The reported test results provide technical benchmarks for the potential recovery of both rare earths and titanium from the project's mineralization.
