Montage Gold Corp. has released an updated Mineral Resource Estimate for its flagship Koné project in Côte d'Ivoire, revealing significant growth in gold resources at both the Koné and Gbongogo Main deposits. The company reported that construction at the project continues to advance rapidly, remaining on-budget and ahead of schedule, with the first gold pour anticipated through the oxide circuit in late Q4-2026.
Extensive Drilling Programs Yield Results
Throughout 2025, Montage Gold conducted an impressive 174,000 meters of exploration, advance grade control, and grade control drilling. Approximately 36% of this drilling was specifically directed toward the Koné and Gbongogo Main deposits, with additional efforts focused on delineating new higher-grade satellite deposits.
At the Koné deposit, the company completed 59,873 meters of grade control and exploration drilling in 2025 alone. This brings the cumulative drilling at Koné to 171,050 meters, representing a substantial increase from the 100,249 meters completed prior to the 2024 Updated Feasibility Study.
Meanwhile, at the Gbongogo Main deposit, 7,292 meters of grade control and exploration drilling have been completed since the beginning of 2025. This brings total drilling at Gbongogo Main to 32,002 meters, compared to just 18,276 meters prior to the 2024 Updated Feasibility Study.
Resource Increases and Grade Improvements
The in-fill and step-out drilling at both deposits, combined with the application of Ordinary Kriging methodology, has enabled better definition of higher-grade zones while improving mineralization continuity and extending overall mineralized envelopes.
Koné Deposit Resource Growth
The Koné deposit has demonstrated remarkable resource expansion. Measured and Indicated Resources increased by 142,000 ounces to reach 4.63 million ounces, with the grade improving by 21% to 0.69 grams per tonne of gold. Inferred Resources saw an even more substantial increase of 749,000 ounces to reach 1.26 million ounces, with grade also improving by 21% to 0.52 grams per tonne of gold compared to last year.
Notably, the Koné deposit now boasts maiden Measured Resources of 229,000 ounces at 0.83 grams per tonne of gold, demonstrating a higher level of resource confidence.
Gbongogo Main Deposit Advancements
The Gbongogo Main deposit also showed significant progress. Indicated Resources increased by 223,000 ounces to reach 783,000 ounces, with grade improving by 3% to 1.51 grams per tonne of gold. Inferred Resources increased by 39,000 ounces to reach 41,000 ounces, with grade improving by 21% to 1.08 grams per tonne of gold compared to last year.
Overall Project Resource Enhancement
The updated Mineral Resource Estimate for the entire Koné project shows overall Measured and Indicated Resources increased by 671,000 ounces to reach 5.88 million ounces, with grade improving by 24% to 0.77 grams per tonne of gold. Inferred Resources increased by 782,000 ounces to reach 1.56 million ounces, with grade improving by 7% to 0.58 grams per tonne of gold compared to last year.
These figures include resources for additional satellite deposits published last year. The Indicated and Inferred Resources for higher-grade satellite deposits now stand at 1.25 million ounces at 1.34 grams per tonne of gold and 303,000 ounces at 1.07 grams per tonne of gold, respectively, highlighting the effectiveness of the exploration program.
Future Exploration and Development Plans
Montage Gold expects to publish updated resources for satellite deposits including Gbongogo South, Koban North, ANV, Yere North, Lokolo Main, Sena, and Diouma North in the coming weeks. Additionally, maiden resources for new discoveries such as Petit Yao and Soman 1 & 2 are expected to be published over the course of 2026.
Exploration remains a strong focus at the Koné project, with a 90,000-meter drill program launched in early 2026. The company continues to advance construction at the project, maintaining its position ahead of schedule and on-budget as it moves toward production.
