• Peregrine Gold’s along strike soil sampling extends central lithium anomaly at Pilgangoora North to over 1km
  • Sampling also traces eastern pegmatite soil anomaly for 400m
  • POW submitted for future drilling at the project


Special Report: Soil sampling at Peregrine Gold’s Pilgangoora North project in WA’s Pilbara region has outlined lithium anomalism over 1km with assays topping up at 1,320 ppm Li2O.

Pilgangoora North is just 5km along strike from Pilbara Minerals’ (ASX:PLS) 414Mt Pilgangoora lithium mine, which produced 620,100t of spodumene concentrate in the 2023 financial year to deliver revenue of $4.1bn and after-tax profit of $2.4bn.

While there has been limited historical exploration at Pilgangoora North, the project does host numerous lithium occurrences in addition to tin, tantalum, gold and lead, while a sequence of ultramafic rocks has the potential to host nickel and copper.

Peregrine Gold’s (ASX:PGD) previous work identified coincident lithium and caesium anomalism near outcropping pegmatites in the southern portion of the tenement.

Infill soil sampling traced a coherent lithium-caesium anomaly over 700m of strike with samples returning up to 613 parts per million (ppm) Li2O and 313ppm caesium.


Sampling extends main central pegmatite

Infill and along strike sampling completed in October as a follow-up to reconnaissance soil sampling has now strengthened the main central pegmatite soil anomaly and extended it north and south with lithium anomalism traced over 1km.

The eastern pegmatite soil anomaly, located east of the central pegmatite zone, also returned anomalous lithium anomalism, is open along strike and can be traced for 400 metres.

Additionally, pegmatites were observed along strike north and south of the soil sampling area and now extend for 1.3km.

PGD also completed detailed geological mapping that is being compiled at present and has lodged a program of work for future drilling.

“The latest soil sampling programme has confirmed geochemically that the lithium soil anomaly now extends for over 1km,” technical director George Merhi said.

“Geological mapping has been completed to better understand the relationship between lithological units and to assist drilling in this portion of the tenement.

“Once heritage clearance has been obtained and the POW approved, reverse circulation drilling can commence.”
