Heavy Rare Earths Limited (ASX: HRE) has released new findings that reshape the potential of its Prospect Hill Project in the northern Flinders Ranges of South Australia. What was once viewed primarily as a tin-focused system is now revealing a strong polymetallic signature, supported by historic drilling that confirms significant silver, copper, lead, and zinc mineralisation alongside high-grade tin.

Impact Minerals Limited (ASX: IPT) has resumed exploration at its 100%-owned Broken Hill Project (NSW), citing stronger metal prices, new in-house copper concepts from the BHP Xplor program, and renewed third-party activity in the district (Figure 1). The Company has begun a progressive review of past work and presents context and results from Platinum Springs as the first step.

A notable announcement by E79 Gold Mines Limited (ASX: E79) securing 100% ownership of the Mountain Home Copper-Gold-Bismuth Project in the Northern Territory. The move, announced on 22 April 2025 (E79 Gold Acquires 100% of the Mountain Home Project), indicates that there may be some activity happening on this project soon.
