Aurum Resources Expands BDT2 Gold Mineralisation Beyond Existing Resource at Boundiali Project, Côte d'Ivoire

Boundiali Gold Project Progress and Resource Expansion Confirmation

Aurum Resources has confirmed that recent drilling at the BDT2 deposit within the Boundiali Gold Project indicates significant resource growth potential, with gold mineralisation identified beyond the current Mineral Resource Estimate boundaries. Managing Director Dr Caigen Wang highlighted that the step-out drilling has extended mineralisation beyond existing resource limits and confirmed the system remains open at depth, emphasizing both grade and scale potential in previously untested zones.

Holding an 80% interest in the BD tenement, the Boundiali Gold Project represents a major growth opportunity within Aurum's portfolio. The project currently boasts a 3.22 million ounce Mineral Resource Estimate following a major update in May 2026, which saw Indicated Resources rise 24% to 1.70 million ounces. This recent drilling is part of a 100,000 metre program at Boundiali aimed at resource expansion and confidence enhancement ahead of a significant resource update targeted for the end of Q3 2026.

Step-Out and Extensional Drilling Outcomes at BDT2 Deposit

The final drilling phase at BDT2 included 10 diamond drill holes totaling 3,565.05 metres, conducted on 100 metre line spacing to test deposit boundaries at depth and along strike. Multiple thick gold intersections were recorded, including 39 metres at 0.79 g/t gold from 372 metres depth (with 3 metres at 5.76 g/t), 0.61 metres at 47.60 g/t from 189.39 metres, and 4.46 metres at 4.23 g/t from 90 metres (including 0.50 metres at 35.19 g/t).

Additional significant intercepts include 3 metres at 4.02 g/t from 124 metres (including 2.30 metres at 5.16 g/t), 15 metres at 0.73 g/t from 116 metres (including 1 metre at 4.20 g/t), and 1 metre at 9.93 g/t from 367 metres. Other results include 12.63 metres at 0.65 g/t from 357.37 metres (with 1 metre at 3.12 g/t), 11.50 metres at 0.69 g/t from 382 metres (including 1 metre at 5.47 g/t), and 18 metres at 0.43 g/t from 198 metres (including 1 metre at 1.81 g/t). All intercepts use a 0.2 g/t gold cut-off with up to 3 metres internal dilution and no top cut applied.

Geological Context and Mineralisation Features of BDT2

The BDT2 gold deposit is situated within a largely underexplored 13 km by 3 km mineralised corridor. Gold mineralisation occurs in a thick, north-south trending sandstone unit sandwiched between hanging wall and footwall volcano-sedimentary rocks. The gold is free milling and associated with fine disseminated pyrite and hydrothermal alteration minerals such as hematite, silica, chlorite, tourmaline, quartz veinlets, albite, and carbonate, indicating favorable conditions for metallurgical processing.

True widths of gold intercepts are estimated at 60-85% of downhole lengths, reflecting variable drilling angles relative to the mineralised zones' dip. Mineralisation remains open along strike and at depth. Aurum's drill rigs have now shifted focus to deposits on adjacent BST and BM tenements as part of the wider exploration program. The company notes initial drilling targeted prominent outcropping anomalies, suggesting further discovery potential in less explored areas.

Supporting Historical Drilling Data at BDT2

Recent results complement earlier exploration drilling at BDT2, which demonstrated consistent gold mineralisation across the deposit. Historical intercepts include 74 metres at 1.00 g/t from 167 metres (including 1 metre at 24.73 g/t), 18 metres at 3.93 g/t from 198 metres (including 5 metres at 11.07 g/t), and 40.60 metres at 1.06 g/t from 299.40 metres (including 6 metres at 2.77 g/t).

Other notable historic intercepts were 4.03 metres at 10.22 g/t from 13.5 metres (including 1.5 metres at 27.13 g/t), 28 metres at 1.54 g/t from 82 metres (including 4 metres at 7.51 g/t), 7.15 metres at 4.71 g/t from 121.15 metres (including 1 metre at 31.24 g/t), 16 metres at 1.79 g/t from 347 metres (including 4 metres at 6.36 g/t), 10.50 metres at 2.39 g/t from 43.50 metres (including 1 metre at 22.81 g/t), 15.78 metres at 1.70 g/t from 121.22 metres (including 6 metres at 2.99 g/t), 33 metres at 0.84 g/t from 146 metres (including 1 metre at 9.95 g/t), and 18 metres at 2.58 g/t from 110 metres (including 2 metres at 28.90 g/t).

Robust Drilling Program and Operational Efficiency

Aurum is conducting one of the region's most intensive and efficient drilling campaigns, operating 16 diamond drill rigs across its Boundiali and Napié projects. The company has scheduled 130,000 metres of drilling for 2026—100,000 metres at Boundiali and 30,000 metres at Napié—aimed at accelerating resource growth and enhancing confidence across both flagship assets.

Managing Director Dr Caigen Wang praised the rapid growth of the Boundiali resource to 3.22 million ounces, with recent drilling results directly contributing to a major resource update planned for Q3 2026. This aggressive drilling strategy underscores Aurum's commitment to advancing Boundiali toward development, with follow-up drilling planned to further test mineralisation beyond current resource limits.

Strong Financial Position to Support Exploration and Development

Aurum maintains a solid financial footing with $54.7 million in cash as of 30 June 2026, providing ample funds to support ongoing drilling, studies, and permitting activities concurrently. This financial strength enables the company to sustain its aggressive exploration program while progressing Boundiali toward production. Environmental approval was secured in May 2026, with a Preliminary Feasibility Study and Maiden Ore Reserve delivered in June 2026, establishing a clear roadmap toward Mining Licences and a Definitive Feasibility Study slated for late 2026.

The $54.7 million cash reserve allows Aurum to fund exploration expansion across both Boundiali and Napié throughout 2026 without immediate capital raising, granting management flexibility to execute strategic goals. This robust financial position distinguishes Aurum from many junior explorers and positions the company to capitalize on exploration upside while advancing Boundiali toward a development decision, with the Definitive Feasibility Study expected by year-end 2026.

Combined Resource Base Fuels Growth Strategy

Aurum's combined resource portfolio totals 4.4 million ounces of gold, consisting of the 3.22 million ounce Boundiali Gold Project and the 1.16 million ounce Napié Gold Project, both in Côte d'Ivoire. This substantial resource base supports advancing multiple development-stage projects while maintaining an active exploration program to extend resources and discover new deposits within its landholdings.

The consolidated 4.4 million ounce resource represents a significant asset base for an Australian-listed junior exploration and development company. Aurum's strategic emphasis on simultaneous development of Boundiali and Napié, backed by planned 130,000 metres of drilling in 2026, reflects confidence in Côte d'Ivoire's mineral potential and commitment to progressing multiple projects toward development decisions within the same economic cycle.

Resource Update and Feasibility Study Schedule

Aurum targets the end of Q3 2026 for the next Boundiali Mineral Resource Estimate update, incorporating the latest BDT2 drilling results. This update aligns with ongoing feasibility studies and permitting, creating a cohesive development pathway. The Definitive Feasibility Study is expected by late 2026, following the Preliminary Feasibility Study and Maiden Ore Reserve delivered in June 2026.

This phased approach reduces technical and economic risks by building on successive study stages. Environmental approval in May 2026 provides regulatory confidence, while integrating new drilling data into the Q3 resource update and late-year Definitive Feasibility Study demonstrates Aurum's commitment to maximizing Boundiali's economic potential.

Exploration Potential and Open Mineralisation Confirmed

Gold mineralisation discovered beyond current Mineral Resource Estimate boundaries at BDT2 confirms the system remains open at depth and along strike, highlighting significant exploration upside within the defined deposit. Aurum notes that drilling has so far focused on prominent outcropping anomalies, indicating substantial potential within the broader 13 km by 3 km mineralised corridor at BDT2 and neighboring BST and BM tenements, where drill rigs have recently relocated.

This exploration upside is highly relevant to investors, suggesting potential for meaningful resource growth beyond the current 3.22 million ounce estimate. The systematic drilling program and planned follow-up drilling in newly identified mineralised zones support Aurum's view of Boundiali evolving into a large-scale development opportunity.

Development Progress and Permitting Milestones

Aurum has made significant strides in developing Boundiali, securing environmental approval in May 2026—a key regulatory milestone. The June 2026 delivery of a Preliminary Feasibility Study and Maiden Ore Reserve underscores the company’s commitment to project advancement, providing the technical and economic basis for Mining Licence applications and the final Definitive Feasibility Study expected later in 2026.

Managing Director Dr Caigen Wang emphasized that the sequential achievement of environmental approval, PFS, and Maiden Ore Reserve establishes a clear pathway toward Mining Licences and DFS completion. This progress validates Aurum’s ability to advance Boundiali through multiple project stages simultaneously, supporting guidance for continued development through 2026, with a development decision anticipated in late 2026 or early 2027.
