Quarterly Activities Report: September 2025

Share This Update

The September quarter marked the first steps of our “pipeline of drill targets” strategy beginning to properly take shape.

The highlight was, of course, the drill testing of the first targets at the Eromanga Heavy Mineral Sands Project in South Australia. However, it is also significant that during this period, we validated new copper and gold targets in the Macquarie Arc that are now ready for drilling in the upcoming quarter. Looking further ahead, investors can now also look forward to the exploration team assessing the very promising silver and gold potential at the Firenze Project in Nevada.

With the Company well-funded, I’m excited about the exploration programs that will unfold over the next 12 months, and it is encouraging to see Altitude fulfil its mission of being an explorer committed to testing the very best high-value targets for our shareholders.
