**Cobra Resources (LON: COBR)** has commenced **in-field permeability trials** at its **Boland Ionic Heavy Rare Earth Project** in **South Australia**, marking a key milestone in the company’s efforts to advance a **low-cost and environmentally sustainable in-situ recovery (ISR) mining approach**.

The trials, set to run for **7–14 days**, will evaluate **aquifer discharge rates** and **orebody permeability**, critical factors in determining ISR feasibility. These field tests build on prior **bench-scale studies**, which achieved **66% heavy rare earth recovery in just 17 days** using **minimal acid**, underscoring the potential for a cleaner and more efficient extraction process.

In a parallel development, Cobra has executed a **Deed of Assignment with the Barngarla Traditional Owners**, securing the **transfer of tenure** for **three key exploration licences (EL 6742, 6774, and 6780)** — areas that host **priority rare earth element (REE) targets**.

**Managing Director Rupert Verco** said the start of in-field trials represents “**a major step toward demonstrating ISR’s potential as a low-cost, sustainable production method for critical heavy rare earths such as dysprosium and terbium**,” adding that the agreement with the Barngarla People reflects the company’s commitment to **strong community partnerships and responsible development**.
