- Perpetual Resources’ exploration identifies fourth pegmatite trend at its Isabella project
- New trend runs sub-parallel and proximal to previously identified pegmatite trends
- Rock chip results expected by late February, maiden drilling to start in H1 2025
Special Report: Perpetual Resources’ ongoing exploration activities at its Isabella project in Brazil’s ‘Lithium Valley’ have identified a fourth pegmatite trend, which could expand its mineralised footprint.
Fieldwork – consisting of follow-up sampling and step-out reconnaissance activities – carried out in February uncovered the new Trend 4, which runs sub-parallel and proximal to previously reported high-grade mineralised spodumene-bearing pegmatite trends that had returned grades of up to 6.8% Li2O.
The discovery is supported by extensive artisanal workings and highlights the potential of Isabella as Perpetual Resources’ (ASX:PEC) exploration efforts have now identified four distinct mineralised corridors extending over 1km each with regional interpretation indicating potential extensions of up to 3km when extrapolated at both ends.
Preliminary field studies have confirmed the presence of lithium-bearing minerals alongside accessory minerals such as elbaite, cleavelandite, feldspar and quartz.
Adding further interest, the new findings support the potential for multiple parallel stacked pegmatites in the region, with potential to discover additional trends.
Isabella project
The Isabella licence sits close to some of the region’s largest and most advanced hard-rock lithium producers and developers.
It is ~10km from Atlas Lithium’s recently approved Neves mine and processing facility and less than 4km from Sigma Lithium’s São José project that hosts significant historical lithium mining activities and ongoing advanced spodumene exploration.
Refined structural mapping at Isabella has interpreted multiple high-confidence spodumene-pegmatite trends extending up to 800m, delineated by artisanal workings targeting the pegmatites. Over 30 artisanal excavations have been identified, featuring substantial underground workings.
PEC’s in-country team is continuing follow-up reconnaissance activities, including targeted high-impact rock chipping, further detailed geological mapping, and local community consultations.
These efforts aim to expand the mineralised footprint, consolidate drill targets, and finalise preparations for a fully drill-ready license in early 2025.
Further rock chip assays results from Isabella – including chips from Trend 4 – are expected by late February. These are expected to confirm new mineralisation along the recently identified trend.
Approvals for drilling have been received and the company plans to launch its maiden program in H1 2025.
