The Paris Silver Project hosts a JORC 2012 Mineral Resource of 24Mt @ 73g/t silver and 0.41% lead for 57Moz of silver and 99kt of lead. It is a shallow, high-grade silver deposit amenable to open pit mining, providing strong leverage to a metal with growing demand across industrial, renewable energy and manufacturing applications. Following the successful completion of a Definitive Feasibility Study in February 2026, the Company is advancing the Project toward development through ongoing permitting, execution readiness and financing activities, while continuing to assess opportunities to grow the resource base both proximal to Paris and across its broader South Australian tenure.
