BOA Resources (BOA) investor relations material

Project position and resource base

• Neds Creek is a 100%-owned flagship project in WA’s Murchison Copper Belt, with granted Mining Leases over Thaduna and Green Dragon and ~1,378 km² of exploration tenements.

• Thaduna and Green Dragon resources total 5.3 Mt at 2.3% Cu for 121 kt contained Cu: Thaduna 4.1 Mt at 2.5% Cu; Green Dragon 1.2 Mt at 1.5% Cu.

• Sandfire Resources is a substantial shareholder at approximately 5.4%.

• Thaduna’s main mineralised zone spans 500 m within a 1.7 km structural trend, extends beyond 600 m vertical depth and remains open at depth.

Ricci Lee drilling

• 46 RC holes for 7,364 m drilled in Aug–Sep 2026; drilling tested 640 m of strike and up to 220 m vertically, defining the Main Lode and a parallel northern Hanging-Wall Lode.

• Main Lode high-grade mineralisation extends over 400 m of strike and 200 m vertical depth; mineralisation plunges north, with modelling to guide resource estimation and follow-up drilling.

• Southern results include 10 m at 3.60% Cu, including 6 m at 5.57%, and 10 m at 2.78%, including 8 m at 3.33%; continuity extends from surface to ~200 m vertical depth.

• Northern results include 22 m at 3.05% Cu, including 9 m at 6.86%, plus 10 m at 1.81% Cu in the Hanging-Wall Lode; continuity extends from surface to >220 m vertical depth.

Exploration pipeline

• Six high-priority targets were tested; five prospects received 92 aircore holes for 5,722 m, targeting mineralisation controls in Thaduna and Green Dragon structural corridors.

• Rooneys aircore drilling extended the interpreted mineralised trend beyond 500 m; results include 4 m at 3.54% Cu from 10 m and 16 m at 2.47% Cu from 58 m.

• Expanded follow-up RC drilling is planned at Rooneys; assays from Blockley, Mueller, Limestone Bore and Ward were pending in the presentation.

• Extensive geophysical, geochemical and drilling datasets are being used to generate and rank further targets; Enigma remains a future exploration opportunity.
