Perpetual Resources has reported multiple high-grade lithium rock chip assays from its Renaldinho and Morro Grande projects in Brazil, confirming a fertile lithium system and setting the stage for a significant drilling campaign in 2026.
- Multiple rock chip samples exceed 1.5% lithium oxide at Renaldinho
- High-grade lithium confirmed alongside caesium, tantalum, and tin
- Renaldinho identified as a priority drill target within Brazil’s Lithium Valley
- Ongoing soil and channel sampling expanding geological understanding
- Diamond drilling planned to refine and test multiple lithium targets
Emerging Lithium Discovery in Brazil’s Lithium Valley
Perpetual Resources Ltd (ASX, PEC) has strengthened its lithium exploration credentials with the release of new high-grade rock chip assay results from its Renaldinho and Morro Grande projects in Brazil’s prolific Lithium Valley. The assays reveal lithium oxide grades as high as 7.08% at Renaldinho, accompanied by elevated levels of caesium, tantalum, and tin, hallmark indicators of a fertile lithium-caesium-tantalum (LCT) pegmatite system.
These results build on Perpetual’s growing footprint in the Minas Gerais region, a globally recognised lithium province. The Renaldinho project, in particular, has emerged as a compelling exploration target with multiple samples exceeding 1.5% lithium oxide, suggesting significant mineralisation potential. The presence of spodumene and amblygonite minerals in artisanal workings further supports the prospectivity of the pegmatite system.
Expanding Exploration and Strategic Drilling Plans
Perpetual’s in-country team is actively advancing exploration with widespread soil sampling, channel sampling of exposed pegmatite faces, and additional rock chip assays underway. These efforts aim to expand the geological model across multiple targets, including the Morro Grande and Mauricio areas within the Igrejinha tenement.
Looking ahead, the company has flagged a diamond drilling program scheduled for 2026, targeting a broad range of priority lithium prospects. This drilling will be critical to delineate the extent and continuity of the mineralisation, moving beyond surface sampling to establish a resource base.
Strategic Positioning in Brazil’s Lithium Sector
Perpetual’s portfolio covers approximately 12,000 hectares in the heart of Brazil’s Lithium Valley, a region that hosts the country’s primary lithium production. Despite the region’s mining history, much of Perpetual’s tenure has seen limited systematic exploration until recently, positioning the company to capitalise on early-stage discovery upside.
Executive Chairman Julian Babarczy emphasised the significance of the results, noting the consistency and quality of the lithium system at Renaldinho. He highlighted the company’s confidence in the project’s potential and the strategic importance of progressing to drilling to unlock value.
While these rock chip assays provide a promising snapshot, the true test will come with the upcoming drilling campaigns, which will clarify the scale and economic viability of the lithium mineralisation. Investors and market watchers will be keenly observing how Perpetual translates these early-stage results into a defined resource.
Bottom Line?
Perpetual’s high-grade lithium assays at Renaldinho set the stage for a pivotal drilling campaign that could reshape its Brazilian lithium prospects.
Questions in the middle?
- How will the upcoming diamond drilling results impact Perpetual’s resource estimates?
- What is the potential scale and grade continuity of the Renaldinho pegmatite system?
- How might Perpetual’s exploration success influence lithium supply dynamics in Brazil’s Lithium Valley?
