Flowsheet Update for Koppamurra Outlines Low Capital Development Pathway

AR3 Identifies Progressive Heap Leaching Development Pathway for Efficient Rare Earths Extraction at Koppamurra

Highlights:

• Metallurgical testwork delivers high recoveries for Magnet Rare Earths (MRE) up to 72% (ranging from 43% to 72%).

• Progressive heap leach development pathway offers lower capital and operating costs compared to tank leach alternative.

• Optionality for modular expansion to scale up production over time across the province.

• Improved environmental sustainability characteristics:

o Very low water consumption

o Reduced power consumption

o Rapid, progressive rehabilitation techniques

• Testwork also indicates lower gangue/impurity profile with higher rare earth in solution characteristics through column leach, favouring this development approach for an economically sustainable basis of development.
