Northern Block Assays Highlight Potential but Central Block Remains Development Focus
Resouro Strategic Metals reports strong assay results from 18 auger drill holes at its Tiros Northern Block in Brazil, confirming significant near-surface titanium and rare earth mineralization. These findings complement the company’s existing resource base and support ongoing development efforts at the adjacent Central Block.
- High-grade titanium dioxide up to 23.9% and rare earth oxides up to 13,074 ppm confirmed
- 18 auger holes reveal consistent near-surface mineralization down to 15 meters
- Northern Block results complement previously reported Central Block resource of 1.4 billion tonnes
- Focus remains on metallurgical test work and engineering studies at Central Block
- Potential for large-scale mining supported by favorable geology and infrastructure
Strong Assay Results at Tiros Northern Block
Resouro Strategic Metals Inc. has released the latest assay results from its auger drilling program at the Tiros Northern Block, part of its titanium and rare earth elements project in Minas Gerais, Brazil. The eighteen drill holes reported confirm the presence of high-grade mineralization near surface, with titanium dioxide (TiO2) grades reaching as high as 23.9% and total rare earth oxides (TREO) up to 13,074 ppm. These results reinforce the continuity of mineralization previously identified in the area and highlight the Northern Block’s potential as a significant source of critical minerals.
Complementing a Robust Resource Base
The Northern Block findings complement earlier drilling results from April 2025 and sit alongside the company’s substantial measured and indicated resource at the Tiros Central Block. The Central Block hosts an estimated 1.4 billion tonnes of mineral resource at 12% TiO2 and 4,000 ppm TREO, positioning Resouro as a notable player in the titanium and rare earth sector. The Northern Block’s near-surface mineralization, often exposed or under thin overburden, offers promising opportunities for future exploration and potential mining operations.
Strategic Focus on Development and Metallurgical Testing
Despite the encouraging Northern Block results, Resouro’s current strategic focus remains on advancing metallurgical test work and engineering studies at the Central Block. Ongoing programs at CIT-Senai and SGS Laboratories in Brazil and Canada aim to optimize processing techniques and support the development of a demonstration plant. This approach reflects the logistical advantages and infrastructure accessibility of the Central Block, which are critical factors for project advancement.
Geological and Operational Context
The Tiros Northern Block is characterized by a plateau where mineralization is hosted within the Capacete Formation. Auger drilling targeted areas along the plateau rim with minimal overburden, facilitating the discovery of high-grade zones. The mineralized layers are horizontal, allowing vertical drilling to effectively capture true thicknesses. The geological setting and assay results suggest a sizeable and continuous mineralized system that could underpin future mining operations.
Looking Ahead
Resouro plans to integrate these new assay results into its broader exploration and development strategy, with scoping studies and environmental assessments anticipated in the coming months. The company’s ability to translate these promising exploration results into a viable mining operation will be closely watched by investors and industry observers alike, particularly given the growing global demand for titanium and rare earth elements.
Bottom Line?
Resouro’s Northern Block assay results bolster the Tiros Project’s potential, but the path to production hinges on Central Block development progress.
Questions in the middle?
- How will metallurgical test outcomes at the Central Block influence project timelines?
- What are the logistical challenges of developing the Northern Block compared to the Central Block?
- Could further drilling expand the high-grade zones at the Northern Block beyond current limits?
