Drilling points to big lithium payday at Perpetual’s Igrejinha

• Perpetual drilling intersects consistently broad zones of pegmatites at the SE Anomaly
• Preliminary logging of 12m interval in hole SEP006 uncovers presence of spodumene
• Follow-up drilling planned to test system extent and depth at SE Anomaly

Special Report: Geological logging of maiden drilling at Perpetual Resources’ Igrejinha project in Brazil’s Lithium Valley has uncovered further evidence that a major pegmatite system is present.

Five of the six holes drilled at the SE Anomaly intersected broad zones of pegmatites with hole SEP006 returning continuous pegmatite over 44m from near the surface.

Preliminary logging of a 12m interval within this zone indicated the presence of spodumene – a mineral known to contain lithium.

Notably, Perpetual Resources’ (ASX:PEC) drilling confirmed 60m of strike continuity with consistent pegmatite intercept widths.

While the extent of mineralisation within the SE anomaly has yet to be confirmed, the strong indication of spodumene in drill chips and mapping indicates that it might strike to more than 300m.

This potential for a major pegmatite discovery is supported by high-grade soil geochemistry, hyperspectral analysis and trenching.

At Target 1, drilling defined continuous, mineralised lithium-caesium-tantalum pegmatites over 200m of strike from surface to >50m depth.

Multiple drill holes have targeted pegmatites beneath historical pollucite workings, highlighting strong mineralisation potential.

Adding interest, visual observations indicate the presence of spodumene while portable XRF readings for pollucite have highlighted Igrejinha as a potential caesium-bearing system.

“The presence of visible spodumene within large pegmatite intersections from drilling at the SE Anomaly is significant, particularly given the rapid turnaround from initial target generation to discovery,” PEC executive chairman Julian Babarczy said.

“Importantly, the mineralisation remains open along strike and at depth, offering exciting exploration upside.

“Following receipt of assays, we will assess further potential, but these early signs underscore the scale potential of this emerging lithium target which sits within a prolific lithium jurisdiction.”

Igrejinha project

Igrejinha is less than 10km from and in the same geological setting as globally significant lithium projects such as Sigma Lithium’s low-cost Grota Do Cirilo complex.

The Lithium Valley holds the lion’s share of the nation’s ~45 hard rock lithium deposits, similar to those mined in WA, and accounts for more than 80% of the country’s known lithium reserves

Further support comes from the substantial investment and strong government backing for critical minerals projects, including recent moves by major Chinese firms like BYD, which have secured exploration ground and established EV manufacturing facilities.

PEC notes that with results indicating the potential for significant extension of the SE Anomaly mineralised system both along strike and at depth, it is now considered to be a primary target for follow-up drilling in subsequent drill programs.

Further drilling is planned to test the extent of mineralisation and to refine its structural and mineralogical model.

Beyond that, the company will focus on receipt and analysis of drill results, further exploration analysis and subsequent planning for future potential drill programs at Target 1, the SE Anomaly and other nearby project areas.
