Octava Minerals (ASX:OCT) plans to conduct up to 2,000m of diamond drilling across 22 holes in mid-November 2025 within the Federation Project in Tasmania.
Drilling will test semi-massive sulphide mineralisation previously intersected from 70m to 210m depth, which remains open. An electromagnetic survey is also scheduled to begin shortly to refine targets ahead of potential step-out drilling.
This news comes after Octava identified indium grades via rock sampling at the Sweeney’s prospect within the Federation Project, strengthening the company’s case for a new polymetallic discovery ahead of drilling later this month.
The results position Sweeney’s as a potential critical-minerals target containing indium, zinc, copper, silver and tin.
Rock chip sampling returned more than 500 parts per million indium in four samples, alongside standout assays including 27.5% zinc, 5.97% tin, 434g/t silver, and 0.92% antimony.
Managing Director Bevan Wakelam says the approvals and assay results reinforce the project’s potential and set up a strong pipeline of exploration activity.
“The recent rock chip assay results continue to confirm excellent grades and highlight the potential for significant polymetallic mineralisation, including indium, at the Sweeney’s prospect,” Wakelam says.
The Federation Project, covering 121km2, is located 12km west to Zeehan in Western Tasmania.
Octava Minerals is a Western Australian explorer focused on targeting copper, base metals, and rare earths.
