Aurum Resources Confirms 220m Depth Extension at Boundiali Gold Project

Depth Extension at BST1 Deposit Unveiled

Aurum Resources (ASX:AUE) has revealed a compelling new chapter in its Boundiali Gold Project story, with drilling results confirming gold mineralisation extending 220 metres vertically below the current Mineral Resource Estimate (MRE) at the BST1 deposit. This significant depth extension not only expands the known gold system but also confirms the deposit remains open at depth, underscoring the project's upside potential.

The standout intercepts at BST1 include 29 metres at 1.00 g/t gold from 444 metres, featuring a high-grade 1-metre interval at 18.14 g/t, and 8 metres at 3.38 g/t from 279 metres with a 1-metre spike at 22.80 g/t. These results will feed into the next MRE update scheduled for the third quarter of 2026, potentially boosting resource confidence and scale.

Robust Drilling Campaign Fuels Resource Growth

The company’s ambitious 100,000-metre diamond drilling campaign is in full swing, deploying 14 rigs across the Boundiali tenements. This program targets both resource growth and the testing of blind discoveries, with a clear focus on converting exploration success into economic value. Recent drilling at the BDT3 deposit also confirmed the gold system remains open, with notable intercepts such as 7 metres at 1.23 g/t gold and 7.09 metres at 1.09 g/t gold, demonstrating consistent mineralisation at depth.

Boundiali’s 3.03Moz resource forms the flagship of Aurum’s portfolio, which now boasts a combined 4.2 million ounces of gold across its Côte d'Ivoire projects, including the 1.16Moz Napié Gold Project. The company’s strong cash balance of $61 million as of 31 March 2026 provides ample runway to sustain exploration and development momentum.

Development Milestones and Strategic Outlook

Aurum is advancing rapidly towards key development milestones. The Pre-Feasibility Study (PFS) for Boundiali is expected in Q2 2026, evaluating open-pit mining and processing options, followed by a Definitive Feasibility Study (DFS) slated for late 2026. The integration of fresh drilling results into these studies will be critical to refining project economics and de-risking the pathway to production.

Managing Director Dr Caigen Wang emphasised the scale potential, noting that the drilling to date has only scratched the surface of the deposit’s possibilities. With all deposits remaining open along strike and at depth, the company’s multi-rig drilling fleet is well positioned to deliver further resource growth and discovery success.

This update builds on Aurum’s recent advances in its 4.2Moz gold projects, where the company outlined its strategy to consolidate resources and progress towards a central processing hub in Côte d'Ivoire. The continued drilling success and robust financial position reinforce Aurum’s standing as a key player in West Africa’s gold exploration scene.

Geological Setting and Technical Details

The Boundiali deposits lie within the Birimian greenstone belt, a prolific gold-producing region in West Africa. Mineralisation is hosted in shear zones within sedimentary and volcanic rocks, characterised by free-milling gold associated with quartz veining and sulphide alteration. Aurum employs state-of-the-art diamond drilling and photon assay techniques to ensure high-quality data, with drill hole spacing and sampling methods designed to support robust resource estimation.

With exploration drilling continuing at other deposits such as BDT2, and regional programs targeting new soil anomalies and geological structures, Aurum is actively expanding its resource base and pipeline of discoveries.
