Adopting a structured, accelerated exploration pathway – from sampling and geophysics to drilling – to set the stage for rapid progress toward resource delineation.
PROJECT OVERVIEW
The Fiery Creek Project represents Aruma’s strategic entry into a high-demand copper precinct in the renowned Mount Isa Inlier in northern Queensland. The Project is situated in a tightly held belt in close proximity to a number of Tier-1 mining companies including, Anglo American, Rio Tinto and FMG Resources.
It hosts multiple prospects such as Piper, Eagle, Fiery Creek, Twilight, and Hellfire within a highly prospective geological setting for copper, silver and antimony as well as IOCG and stratiform copper systems. Aruma is applying a systematic approach to exploring the Project area.
GEOLOGICAL SETTING AND HISTORICAL WORK
Positioned within reactive dolomitic and carbonate-rich units of the McNamara Group, the Project hosts structural features typical of globally significant copper systems, plus red‑rock hematite alteration zones associated with copper mineralisation.
Historic surface sampling by Sumitomo and Anglo American returned very high grade copper grades up to 36% Cu, along with 25.4% Cu and 15.2% Cu in other samples. In addition, previous drilling by MIM in the 1990s intersected broad copper zones at the Piper Prospect including; 44m @ 0.2% Cu and 26m @ 0.14% Cu, further supporting the Prospect’s potential .
EXPLORATION ACTIVITIES
Surface Sampling
Aruma completed a first-phase sampling program at the Piper prospect in late 2024 which delivered multiple high-grade copper assays including; 11.83% Cu, 11.53% Cu, 9.95% Cu and 9.53% Cu alongside silver grades of up to 31.3 g/t Ag and elevated antimony values to 10,883ppm Sb. These results reaffirmed the prospectivity of the Piper target area.
Geophysical Surveys
Aruma carried out detailed ground gravity and induced-polarisation (IP) surveys over the Piper and Fiery Creek Prospects. These confirmed two chargeability anomaly zones, each extending ~300 m strike, aligned with gravity highs and copper geochemical trends. These results were coincident with Aruma’s sampling results and the historic drill results reported by the Company, and combined delivered a priority drill-ready target.
Maiden Drilling
The Company commenced its maiden drilling program, targeting the Piper Prospect in August 2025. The program comprised nine reverse circulation (RC) holes for approximately ~1,400m targeting coincident gravity, IP and geochemical anomalies.
Aruma plans to systematically explore other priority prospects within the Fiery Creek Project area.
