Aurum Resources Ltd (ASX:AUE) has delivered a significant upgrade to its Boundiali Gold Project in Côte d'Ivoire, reporting a 53% increase in Indicated Mineral Resources to 920,000 ounces of gold.
The update lifts the project’s total resource base to 2.41 million ounces, reaffirming its position as one of West Africa’s fastest-advancing gold discoveries.

Major uplift in resource confidence
The latest JORC-compliant estimate follows infill drilling at the BMT3 deposit, which now hosts 7.6 million tonnes (Mt) at 1.3 g/t gold for 320,000 ounces in the Indicated category, representing a substantial uplift from the previous estimate.
Aurum’s Boundiali Gold Project
Across all deposits, Boundiali now hosts 2.41 million ounces (Moz) at 1.0 g/t gold, comprising:
- Indicated: 26 Mt @ 1.1 g/t for 920,000 ounces.
- Inferred: 51 Mt @ 0.9 g/t for 1.51 Moz.
A higher-grade component of 1.32 million ounces at 1.7 g/t (using a 1.0 g/t cut-off) underscores the project’s potential for early high-margin production.
Highlighting growth trajectory
Aurum's managing director Dr Caigen Wang said the result reflected the success of an aggressive two-month infill drilling campaign and the benefits of using the company’s own fleet of diamond rigs.
“Our team has achieved a 320,000-ounce increase in the Indicated Resource component from the MRE dated July 31, 2025,” Wang said.
“These higher-confidence resources not only de-risk our project but also allow us to submit mining licence applications on BD and BM to support our BST mining licence application and advance our goal of developing an open-pit mining operation at Boundiali.”
He added that multiple untested targets remain across the Boundiali tenure, providing a clear pathway for further resource expansion.
Exploration and development advancing
Aurum is continuing an extensive 100,000-metre drilling program for calendar year 2025, with additional assays pending and the next major resource update scheduled for early Q1 2026.
A pre-feasibility study (PFS) is also under way and expected to be completed in the same quarter, assessing the project’s technical and economic potential.
The company remains in a strong financial position, with A$40 million in cash and Montage Gold shares to fund ongoing exploration and study work.
Group resources exceed 3.2 Moz
Including the 0.87-Moz Napié Project, Aurum’s total group resources now stand at 3.28 million ounces of gold.

A 30,000-metre drilling program is in progress at Napié to expand its resource base, with an updated estimate also targeted for Q1 2026.
Situated in Côte d'Ivoire’s prolific greenstone belt — host to major operations such as Syama, Sissingué, Koné and Tongon — the Boundiali Project continues to emerge as a key growth asset for Aurum’s West African gold portfolio.
