TR8: IP Results Increase Scale of Walparuta Copper-Gold System

Tarrina Resources announced highly positive Induced Polarisation (IP) survey results from its Walparuta Copper-Gold Project in South Australia, confirming a large-scale IOCG system extending over 4-5 km of strike and to depths of 350-500m. The survey identified numerous strong chargeability anomalies, with several exceeding 70 mV/V, which correlate well with existing magnetic, gravity, and copper-gold soil anomalies, significantly upgrading the project's discovery potential. These integrated geophysical targets define multiple high-priority drill targets, and the company plans to commence its maiden drill campaign once approvals are received.

Drill Results: New Copper Discoveries - Manna Hill

Cobra Resources plc announced new copper discoveries at its Manna Hill project in South Australia, with initial analytical results from ongoing slim-line Reverse Circulation drilling. Highlights include 32m at 0.7% copper from 52m in porphyry-style alteration and 58m at 0.46% copper from 12m in a newly discovered skarn. These results extend known mineralization, identify new zones, and suggest potential for a larger porphyry system, leading to an expansion of the current drill program.
