The Poochera Project comprises one 100% owned exploration licence (EL6733), which covers an area of 329km² in the Eastern Eucla Basin of South Australia.

Project Summary

The project is located adjacent to major halloysite-kaolin deposits, including the Great White Kaolin Project, but has never been systematically explored for kaolin-halloysite.

The Eucla Basin contains sequences up to 300m thick of Tertiary marine, coastal and paleochannel sediments. Kaolin-halloysite deposits within the area of the Poochera Project are typically formed where acidic saline groundwater was developed during oxidation of lignitic, pyritic sands of the Eocene Pidinga Formation within buried fluvial channels. Widespread weathering involving the acidic saline groundwater has formed several significant kaolin deposits and occurrences on the Eyre Peninsula.

Poochera Project Map


  • Local geology of the Poochera Project appears to be analogous to that of major nearby Halloysite-Kaolin deposits.
  • Located proximal to the Great White Deposit (34.6Mt @40.9% Kaolinite & 5.3% Halloysite) and 20km North-east of the Hammerhead Deposit (51.5Mt @42.7% Kaolinite & 6.5% Halloysite).[1]


  • Viridis has planned a systematic exploration program, consisting of surface mapping, soil sampling and aircore drilling, with metallurgical test work intended to be undertaken on any kaolin identified within the Project area.
  • In September 2022, Viridis commenced its maiden aircore drilling program at the Poochera Project, planning to drill up to 60 holes for 3,000m to an average depth of 50m.
