BOA Resources Limited has reported maiden aircore drilling at Limestone Bore in Western Australia returning high-grade copper intersections including 32 metres at 1.91 percent copper.

Cygnet Capital Group has reported, BOA Resources Limited has released an exploration update detailing assay results from maiden aircore drilling at the Limestone Bore prospect within its 100%-owned Neds Creek Copper Project in Western Australia.

BOA Resources Limited is an ASX-listed mineral exploration company focused on copper discovery in Western Australia. The Neds Creek Project covers 1,378 square kilometres across an area of approximately 60 kilometres by 40 kilometres in the northeastern arm of the Paleoproterozoic Yerrida Basin within the Capricorn Orogen. The tenement package surrounds the historic Thaduna and Green Dragon copper mines, which BOA acquired in full on 14 October 2026, and lies east of the DeGrussa and Monty deposits.

Limestone Bore aircore results and structural trends

BOA completed an 18-hole, 1,355-metre aircore program at Limestone Bore, testing an area concealed beneath transported palaeo-drainage and sheet wash sediments located more than 7 kilometres west of previously drilled prospects:

• East-West mineralised structure (26NCAC0076): Drilling identified an east-west striking, north-dipping structure that returned 32 metres at 1.91% copper from 27 metres depth, including 18 metres at 3.03% copper from 32 metres. This zone aligns with historic hole NCAC0391, which recorded 10 metres at 1.28% copper.
  • North-Northwest mineralised structure (26NCAC0069 & 26NCAC0071): A second interpreted structural trend returned multiple mineralised intervals. Hole 26NCAC0069 intersected 29 metres at 1.73% copper and 0.5 g/t silver from 3 metres (including 9 metres at 4.77% copper from 17 metres) and a deeper zone of 13 metres at 0.88% copper and 2.3 g/t silver from 52 metres (including 3 metres at 2.40% copper and 6.0 g/t silver). Hole 26NCAC0071 returned 10 metres at 1.83% copper and 4.8 g/t silver from 67 metres (including 3 metres at 4.62% copper and 12.4 g/t silver from 73 metres).
  • Mineralisation styles: Geological logging recognised two distinct styles: shallow supergene copper mineralisation with low silver content, and deeper silver-bearing copper mineralisation associated with carbonaceous structures.

Regional exploration context and exploration pipeline

BOA reported that Limestone Bore represents a concealed target discovered through shallow geochemical drilling rather than surface outcropping. The structural and mineralisation characteristics show similarities to fault-hosted mineralisation recognised at the Ricci Lee and Rooneys prospects.

The company completed a $9.2 million share placement to fund accelerated exploration, with Tranche 2 subject to shareholder approval at the Annual General Meeting scheduled for 30 November 2026.

What to watch next

• Receiving and reporting pending aircore assay results from the Blockley, Ward and Mueller prospects.
  • Recommencing drilling at Neds Creek by the end of November 2026, focusing on depth extensions at Ricci Lee and further testing at Rooneys.
  • Refining structural interpretations to determine orientation and spacing for follow-up aircore and reverse circulation drilling at Limestone Bore.
  • Holding the Annual General Meeting on 30 November 2026 regarding Tranche 2 of the placement.

Risk and uncertainty

All reported drill intersections represent downhole lengths, and true mineralisation widths are not yet known. In addition, the geometry, structural strike and lateral extent of the mineralised zones remain interpreted, requiring further drilling to establish their dimensions. Assays from drilling at Blockley, Ward and Mueller remain pending, and Tranche 2 of the capital raising remains subject to shareholder approval at the upcoming AGM.

Outlook

BOA Resources Limited has reported maiden aircore drilling results from Limestone Bore, highlighted by 32m @ 1.91% Cu (26NCAC0076) and 29m @ 1.73% Cu (26NCAC0069) across two interpreted structural trends located over 7km from known deposits. The reported results outline both shallow supergene and deeper silver-bearing copper mineralisation. Recommencing drilling at Ricci Lee and Rooneys in late November and receiving pending assays from Blockley, Ward and Mueller represent the primary disclosed upcoming milestones.
