In-Field Permeability Study Update
Cobra Resources PLC has received final permission from the Government of South Australia Department for Environment and Water, in the form of a Discharge to Well Permit, to commence in-field permeability studies at the Boland Ionic Rare Earth Project. The permit authorizes the discharge of water directly into the company's installed wells. The company will inject a tracer dye into the mineralisation and monitor the time taken for the dye to migrate between the discharge well and an extraction well to test the permeability of Boland's confined aquifer mineralisation. The Australian and US Governments also signed a US$8.5Bn framework agreement to fast track approval timelines for critical mineral projects.

Final permit received - field testing to commence soon aimed at confirming the highly productive flow rates being achieved in laboratory ISR studies
Cobra (LSE: COBR), a South Australian mineral exploration and development company, is pleased to announce that the final permission required to commence in-field permeability studies at the Boland Ionic Rare Earth Project has been received.
The Government of South Australia Department for Environment and Water has approved a Discharge to Well Permit. This permit authorises the discharge of water directly into the Company's installed wells which enables the Company to test the permeability of Boland's confined aquifer mineralisation by injecting a tracer dye in to the mineralisation and monitoring the time taken for the dye to migrate between the discharge well and an extraction well.
Preparations are advanced to commence in-field permeability tests as soon as practicable. Field tests will provide an infield measure of the rate of permeability achievable through the in-situ recovery ("ISR") process, aiming to emulate the exceptional permeability rates achieved at laboratory scale.
The Boland Project is unique when compared to traditional ionic clay hosted rare earth ("REE") deposits as REEs have been mobilised from underlying weathered granites (saprolite) and absorbed to fine organics within the Pidinga Formation, a highly permeable paleo-sediment bound by impermeable clays. This unique environment enables ISR, the lowest cost and most sustainable form of mining.
Rupert Verco, Managing Director of Cobra, commented:
"It's pleasing to get these permits on the day that the Australian and US Governments signed a US$8.5Bn framework agreement to fast track approval timelines for critical mineral projects!
Being able to replicate similar permeabilities to those achieved in scaled laboratory tests in a field environment will provide robust, high confidence mining parameters for use with future economic studies. We're excited to take our groundbreaking laboratory work into the field."
