Altitude Minerals ASX: ATT (formerly Copper Search ASX: CUS) is pleased to announce new HMS sample results for EL7071, part of the Eromanga Basin Heavy Mineral Sands Project, South Australia.
HIGHLIGHTS
- New HMS assemblage samples on EL7071 Nilpinna contain high-value zircon and titanium minerals – rutile, ilmenite and leucoxene
- Results support interpreted drill targets on EL7071 from magnetic data
- The Eromanga Basin is host to significant HMS discoveries, including recent finds by Petratherm (ASX: PTR) and Marmota (ASX: MEU), underscoring the region’s strong HMS potential
- New Assay highlights of pan-concentrated grab samples include:
- 30% zircon, 40% Ilmenite, 10% leucoxene, 5% Rutile (CUSHM011)
- 25% zircon, 45% Ilmenite, 10% leucoxene, 5% Rutile (CUSHM012)
- 25% zircon, 50% Ilmenite, 10% leucoxene, 5% Rutile (CUSHM008)
LEARN MORE ABOUT HEAVY MINERAL SANDS
WITH THE ALTITUDE MINERALS PODCAST
- These new samples complement those taken nearby on tenement EL6195 in April
- New grab samples confirm the presence of HMS at the surface on EL7071 in the vicinity of linear magnetic anomalies, which may be potential strandlines under a thin cover
- Historical drill holes indicate that the William Creek Area (EL6195, EL7071 and EL7072) has an extensive thickness of known HMS target horizons
- Titanium is listed as a critical mineral by the U.S. and EU for its key role in aerospace, defence, and medical sectors—vital for security, supply chains, and tech independence
Likewise, the encouraging stream sediment samples identified in a potential bay-shaped trap site on the Douglas Creek tenement are also an exciting drill target. I look forward to drill testing both target areas shortly.
NEXT STEPS
- Heritage survey is planned for late August
- A drilling permit application has been submitted
- Drilling rig secured for an expected September commencement of drilling
(subject to heritage and permitting) - The planned 4,000m drilling program is expected to take two weeks

I am very pleased to see the Company now positioned to drill test the first in our pipeline of drill targets with high-impact shallow air-core drilling in September.
