Investigator has advanced the Paris Silver Project Definitive Feasibility Study (DFS) by confirming a 1.5 Mtpa processing scale as the optimal design for development. The decision follows detailed financial and engineering analysis, ensuring the project balances value, deliverability, and funding resilience.

The updated Process Design Criteria now incorporates recent processing refinements, including the adoption of a wet Tailings Storage Facility (TSF) and outcomes from the ongoing value-engineering work that has already removed approximately A$18 million in capital cost from the plant design. With permitting now underway, Investigator is finalising the process flow sheet and moving into detailed engineering, maintaining strong momentum toward first silver pour.
