Highlights

  • September-quarter drilling at Mandilla included 141 RC holes and seven diamond holes.
  • A land-use agreement was executed for the Mandilla and Spargoville tenements.
  • The company reported approximately AUD 59 million cash at 30 September 2026.
  • Mandilla definitive feasibility work continues, with completion targeted in early 2027.

Astral Resources NL (ASX:AAR) explores and advances gold projects in Western Australia, with development planning centred on Mandilla and associated deposits near Kalgoorlie. The company has continued drilling, technical evaluation and land-access work during 2026. Astral shares closed at AUD 0.145 on 5 November 2026, with technical and approval work continuing into the final quarter. Its recent disclosures place the emphasis on the Mandilla definitive feasibility study, the Theia drilling program and permitting work needed before any construction decision. These are project-development steps, rather than evidence of commercial gold production.

Mandilla Drilling and Resource Evaluation

Astral's September 2026 Quarterly Report recorded 141 reverse-circulation holes covering 14,468 metres at Mandilla, alongside seven diamond holes covering 4,465 metres. The reverse-circulation work primarily addressed the proposed first-stage open pit at Theia; the diamond program tested mineralisation at depth. By the October reporting period, 18 holes of an expanded 21-hole deep-drilling program had been completed. Assays released during and after the quarter added geological information to the assessment of the orebody. A drill intersection is not automatically equivalent to a mineable reserve, and reported downhole lengths should not be treated as true widths. For Astral Resources NL (ASX:AAR), the practical issue is how these results affect resource confidence, mine scheduling and ultimately the study design.

Land Access and Project Development

An August 2026 land-use agreement with the Marlinyu Ghoorlie Native Title Claimant Group covered Mandilla and Spargoville. It establishes heritage protocols and clearance processes relevant to future development activity. Astral also reported transactions intended to consolidate tenure within the proposed development footprint, including agreements involving adjacent mineral rights. Such arrangements address administrative and access considerations, but do not themselves constitute development approval. At Feysville, the company reported assays from a 92-hole, 5,229-metre infill drilling program at Think Big. An updated Spargoville mineral resource estimate of 8.5 million tonnes at 1.0 grams per tonne gold for 281,000 ounces was announced in October 2026. The estimate describes identified resources under its stated classification assumptions, not gold already extracted or sold.

Funding, Timetable and Project Risks

At 30 September 2026, Astral reported approximately AUD 59 million in cash, compared with approximately AUD 65 million in the preceding quarter. This is a useful measure of funds available for studies, drilling and corporate expenditure, but a project construction budget requires separate assessment. The company targeted completion of its Mandilla definitive feasibility study during the March 2027 quarter and envisaged a subsequent Investment decision. Timing remains dependent on further engineering, environmental submissions, tenure administration and other approvals. Astral Resources NL (ASX:AAR) also indicated continued infill drilling and work at Feysville and Spargoville. Future reporting can establish whether resources, Capital requirements and the development timetable change as that work progresses.

Key Insights

Astral Resources NL (ASX:AAR) entered the final part of 2026 with active drilling programs, additional access arrangements and cash resources to advance feasibility work. The important distinction is between favourable geological observations and the commercial assumptions that must be tested before mine development. Completion of the Mandilla study, subsequent permits and any final investment decision remain the principal reported milestones. The company has not presented the drilling programs as completed commercial Mining operations.
