New Pegmatite Target Pico Grande Identified with 600m x 400m Cs-Rb-Ga Anomaly
Perpetual Resources has identified a new pegmatite target, Pico Grande, at its Igrejinha Project in Brazil, adding to two existing prospects and setting the stage for trenching and drilling campaigns in 2026.
- Discovery of Pico Grande pegmatite target with large Cs-Rb-Ga soil anomaly
- Igrejinha Project now hosts three significant pegmatite prospects
- Trenching program scheduled for March-April 2026 to test soil anomalies
- Mid-year diamond drilling planned to follow trenching results
- Project located in Brazil’s Lithium Valley, a prolific LCT pegmatite province
New Pegmatite Target Emerges at Igrejinha
Perpetual Resources Ltd (ASX:PEC) has announced the discovery of a new pegmatite target named Pico Grande within its Igrejinha Project in Minas Gerais, Brazil. This follows a recent soil geochemistry program that revealed a large, coincident anomaly of caesium, rubidium, and gallium; elements indicative of lithium-caesium-tantalum (LCT) pegmatite systems. The anomaly spans approximately 600 by 400 metres and is centred on a topographic high, suggesting the presence of a concealed pegmatite body.
Expanding a Growing Pegmatite Camp
Pico Grande is situated roughly 750 metres northwest of the Morro Grande pegmatite, which has already demonstrated high-grade critical mineralisation, including caesium grades up to 17%. Alongside the Mauricio Target, these three prospects now form a coherent cluster within the Igrejinha tenure, highlighting the project's potential as a significant pegmatite camp. The soil sampling results also confirmed lithium and caesium anomalies at Mauricio, refining drill targeting for future exploration.
Next Steps: Trenching and Drilling
Perpetual plans to commence an extensive trenching program in March and April 2026 to systematically test the soil anomalies at Pico Grande, expand testing around Morro Grande, and assess priority targets at Mauricio. These trenching results will inform a targeted diamond drilling campaign scheduled for mid-2026, aiming to delineate extensions of the known Morro Grande pegmatite, explore the newly identified Pico Grande body, and further evaluate the Mauricio Target.
Strategic Position in Brazil’s Lithium Valley
The Igrejinha Project lies within Brazil’s renowned Lithium Valley, a globally recognised province for LCT pegmatite deposits. Perpetual is earning up to 90% exploration rights over the project area, which covers approximately 12,000 hectares of highly prospective ground. The company’s systematic exploration approach, combining soil geochemistry with trenching and drilling, continues to advance its critical minerals portfolio in this strategic region.
Outlook
While the discovery of Pico Grande adds momentum to Perpetual’s exploration efforts, the economic viability of this new pegmatite system remains to be confirmed through upcoming trenching and drilling. The company’s disciplined testing phase will be closely watched by investors eager for further evidence of substantial lithium and critical mineralisation in the camp.
Bottom Line?
Perpetual’s new pegmatite discovery at Igrejinha sets the stage for a pivotal exploration phase that could reshape its lithium prospects in Brazil.
Questions in the middle?
- Will trenching confirm the extent and grade of mineralisation at Pico Grande?
- How might the new discovery impact Perpetual’s resource estimates and valuation?
- What are the timelines and expected outcomes for the mid-year drilling campaign?
