- Preliminary logging of 12m interval in gap SEP006 uncovers presence of spodumene
- Observe-up drilling deliberate to check system extent and depth at SE Anomaly
Particular Report: Geological logging of maiden drilling at Perpetual Sources’ Igrejinha challenge in Brazil’s Lithium Valley has uncovered additional proof {that a} main pegmatite system is current.
5 of the six holes drilled on the SE Anomaly intersected broad zones of pegmatites with gap SEP006 returning steady pegmatite over 44m from close to the floor.
Preliminary logging of a 12m interval inside this zone indicated the presence of spodumene – a mineral identified to include lithium.
Notably, Perpetual Resources’ (ASX:PEC) drilling confirmed 60m of strike continuity with constant pegmatite intercept widths.
Whereas the extent of mineralisation throughout the SE anomaly has but to be confirmed, the sturdy indication of spodumene in drill chips and mapping signifies that it would strike to greater than 300m.
This potential for a serious pegmatite discovery is supported by high-grade soil geochemistry, hyperspectral evaluation and trenching.
At Goal 1, drilling outlined steady, mineralised lithium-caesium-tantalum pegmatites over 200m of strike from floor to >50m depth.
A number of drill holes have focused pegmatites beneath historic pollucite workings, highlighting sturdy mineralisation potential.
Including curiosity, visible observations point out the presence of spodumene whereas transportable XRF readings for pollucite have highlighted Igrejinha as a possible caesium-bearing system.
“The presence of seen spodumene inside massive pegmatite intersections from drilling on the SE Anomaly is important, significantly given the fast turnaround from preliminary goal technology to discovery,” PEC government chairman Julian Babarczy mentioned.
“Importantly, the mineralisation stays open alongside strike and at depth, providing thrilling exploration upside.
“Following receipt of assays, we’ll assess additional potential, however these early indicators underscore the dimensions potential of this rising lithium goal which sits inside a prolific lithium jurisdiction.”
Igrejinha challenge
Igrejinha is lower than 10km from and in the identical geological setting as globally important lithium initiatives resembling Sigma Lithium’s low-cost Grota Do Cirilo complicated.
The Lithium Valley holds the lion’s share of the nation’s ~45 onerous rock lithium deposits, just like these mined in WA, and accounts for greater than 80% of the nation’s identified lithium reserves
Additional assist comes from the substantial funding and robust authorities backing for essential minerals initiatives, together with current strikes by main Chinese language companies like BYD, which have secured exploration floor and established EV manufacturing services.
PEC notes that with outcomes indicating the potential for important extension of the SE Anomaly mineralised system each alongside strike and at depth, it’s now thought of to be a major goal for follow-up drilling in subsequent drill packages.
Additional drilling is deliberate to check the extent of mineralisation and to refine its structural and mineralogical mannequin.
Past that, the corporate will concentrate on receipt and evaluation of drill outcomes, additional exploration evaluation and subsequent planning for future potential drill packages at Goal 1, the SE Anomaly and different close by challenge areas.
