Tivan upgrades Speewah estimate

The latest geochemical analysis from the Geological Survey of NSW has shown promising prospects across the state for the mining of high-purity silica.

Rox Resources (ASX: RXL) has delivered a significant high-margin production target profile in a definitive feasibility study (DFS) for its Youanmi gold project in WA.

Terra Metals (ASX: TM1) has observed zones of massive sulphide mineralisation in its first diamond drillhole of 2026 at the Southwest prospect within the Dante project in WA.The hole, SWDD011, targeted a geophysical anomaly identified using downhole electromagnetic (DHEM) surveying, located near a previous high-grade intersection.The company reported that multiple zones of semi-massive to massive sulphides were observed within a 320m mineralised interval dominated by disseminated and net-textured sulphides.Terra managing director Thomas Line saysthe results support the company’s geological model and confirms the effectiveness of DHEM in targeting sulphide mineralisation.“The visual interception of multiple zones of massive sulphides in our first 2026 diamond hole at Southwest is a major exploration milestone and a strong validation of our geological model” he said.“The result provides compelling evidence that we are vectoring into a richer massive sulphide component within the broader Southwest magmatic PGM-Cu-Ni sulphide system.”Assays for SWDD011 are pending and expected within eight to 12 weeks.The Southwest prospect forms parts of the broader Dante project in the West Musgrave region, a large-scale multi-metal discovery of nickel, copper and platinum group elements.

Recent drilling and surface sampling activities at Sky Metals’ (ASX: SKY) Tallebung tin project have identified significant extensions of the known mineralisation, outlining new mineralised positions east and south?east of the current footprint.
