After a very productive end to 2025, with testing of multiple high-priority targets in back-to-back drill programs, the March quarter was about analysing the results in detail and prioritising the target pipeline through low-cost fieldwork to make multiple compelling targets drill-ready in both Australia and Nevada.
The highlight for me was receiving the assays from drilling across the Pipe Targets and T55 at the Byrock Project in NSW, and seeing many of the pathfinder elements and other geological signatures of a “pencil” porphyry copper-gold system. At Altitude, we believe in testing targets that have big rewards for our shareholders, and while it is very early days, the results give me a lot of encouragement that we are on the right path in the Macquarie Arc. As a result, we have also elected to advance to Stage One of the Earn-in with Nimrod Resources, and I look forward to continuing to build on our partnership with them.
As always, our aim is to maintain a pipeline of targets, and the team has done a great job validating targets at the Firenze Silver-Gold Project through the US winter months. This included completing CSAMT geophysics, drone magnetics, structural and alteration mapping, and integrating all of that new information into a comprehensive 3D model of the project. Combined with the appointment of our highly experienced US-based Principal Geologist, Gabe Graf, during the quarter, this work has enabled us to design an exciting drilling program that will test a 1.2 km long structural corridor that has hosted some very high-grade silver & gold rock chips at surface.
We also continue to evaluate new opportunities and divest properties that don’t meet technical criteria. Overall, investors can look forward to a steady stream of exploration news through the rest of the year with compelling strategic metals & gold drill targets in both Nevada and NSW.

Results Received: Macquarie Arc, NSW
- ltitude Minerals (‘Altitude’, ‘ATT’ or the ‘Company’) received positive aircore drill results from the Pipe Targets at the Byrock Project in the Macquarie Arc, NSW, with three of the seven targets (P38, P37, P01) prioritised for follow-up RC drilling
- Pathfinder elements Sb, As, Bi, Te, Se, Sn, W and Mo, together with pervasive propylitic alteration, were identified in the aircore drilling – consistent with the alteration halo surrounding a Cu-Au porphyry system (Halley et al., 2015)
- Following these positive results, Altitude elected to advance to Stage One of the Earn-in and Joint Venture Agreement with Nimrod Resources Limited, committing to spend a further $1.35m over two years to earn a 51% interest in the Byrock Project
- The first-ever drillhole at Target T55 intersected a calc-alkaline monzodiorite porphyry intrusion with pervasive propylitic alteration beneath cover – providing direct geological support for the Company’s interpreted north-west extension of the Macquarie Arc
Validated: Firenze Silver Gold Project Nevada, USA
- Altitude completed target validation at the Firenze Silver-Gold Project in Nevada, after conducting extensive CSAMT and drone magnetic geophysical surveys, detailed structural and alteration mapping, and integrating all datasets into a 3D targeting model
- Mr Gabe Graf appointed Principal Geologist – USA, bringing more than 17 years’ experience across North American mineral systems, including senior technical roles at Newmont Mining Corporation (Nevada) and Northern Star Resources (Alaska)
- Subsequent to quarter end, the Altitude team released the plans for a fully permitted 2,600m (9-hole) RC drill program to test the high-priority drill targets along a ~1.2km NWSE structural corridor at Firenze Silver & Gold Project, Nevada
