CANAMERA ADVANCES BRAZILIAN REE PLATFORM: 10-HOLE DUE DILIGENCE PROGRAM UNDERWAY AT PATOS AS COMPANY EVALUATES THIRD IONIC CLAY ACQUISITION

Canamera Energy Metals Corp. has commenced a 10-hole auger drill program totalling approximately 100 metres at the Patos rare-earth project, located in Presidente Olegario, Minas Gerais, Brazil. Drilling is being conducted as due diligence to evaluate the project's potential for ionic adsorption clay-hosted rare-earth mineralization prior to finalizing a property option agreement (please see news release dated Feb. 26, 2026). The program is expected to be completed within approximately two weeks of commencement, after which samples will be submitted to a certified laboratory for analysis.

The Patos program is part of Canamera's strategy to evaluate a third prospective ionic clay REE project in Brazil, complementing the company's continuing exploration at the Turvolandia and Sao Sepe projects.

The project is underlain by the Patos formation, a member of the Mata da Corda Group -- the same stratigraphic package currently being advanced for potential ionic clay REE mineralization by multiple operators active in Minas Gerais. The auger program is designed to characterize the regolith profile across the property and assess the potential for REE enrichment within the lateritic weathering horizon developed over igneous basement. Assay results will be disclosed upon receipt and review and will inform the company's decision regarding exercise of the Patos option.

"Drilling at Patos represents an important next step in our strategy to build a diversified, Brazil-based prospective ionic clay REE platform," stated Brad Brodeur, chief executive officer of Canamera Energy Metals. "The geological setting at Patos -- lateritic weathering developed over igneous basement within the Mata da Corda Group -- is consistent with the profile hosting mineralization at Turvolandia, where our auger program has returned encouraging results. The drill-gated structure of this acquisition allows us to conduct meaningful on-ground due diligence at minimal cost before committing to the full option, substantially reducing our acquisition risk while advancing the buildout of our Brazilian REE platform."

Property description

The Patos project covers 15,979 hectares in Presidente Olegario, Minas Gerais, Brazil, held under eight prospecting licences (ANM IDs: 830763/2024-830771/2024). The property is located approximately 330 kilometres from Belo Horizonte and is road accessible. The project is subject to a letter of intent signed Feb. 26, 2026.

Geology and exploration rationale

Ionic adsorption clay REE deposits are characterized by rare-earth elements adsorbed onto clay minerals within lateritic weathering profiles developed over igneous basement rocks. This deposit style is amenable to low-cost, low-impact extraction using dilute acid leach processing, requiring no crushing or milling of ore. Ionic clay deposits account for the majority of global production of separated magnet-critical rare-earth oxides -- neodymium, praseodymium, dysprosium and terbium -- which are essential to the permanent magnets used in electric vehicles, wind turbines and defence applications.

At Patos, the auger program is targeting the lateritic weathering horizon developed over kamafugite -- an ultramafic to mafic igneous rock of the Mata da Corda Group -- interpreted as a potential parent rock source for ionic clay REE enrichment. The regolith profile observed during the current program consists of a surficial Red Latosol underlain by a ferruginous duricrust (canga), beneath which kamafugite-derived material is present. Kamafugite-associated material becomes increasingly dominant below approximately five metres depth. At approximately eight metres, kamafugite gives way to fine sandstone of the Areado Group. The target REE mineralization is interpreted to be hosted within the clay-rich weathering horizon developed over the kamafugite basement.

Due diligence drill program

The 10-hole auger program is expected to be completed within approximately two weeks. All holes are drilled vertically. Samples will be submitted to SGS GEOSOL in Vespasiano, Minas Gerais (ISO 9001:2015 and ISO 14001:2015 certifications ABS32982 and ABS 39911), for multielement ICP-OES/MS analysis, including all rare-earth elements. The QA/QC (quality assurance/quality control) program includes the regular insertion of certified reference materials, blank standards and field duplicates.

The program targets areas of kamafugite occurrence at depth across the property, including lower topographic positions associated with ferruginous duricrust development, which are characteristic of a mature lateritic weathering profile.
