Montage Gold Corp Announces Grade Control Results And Resource Increase For Koné And Gbongogo Main Deposits
Montage Gold Corp. reported an updated Mineral Resource Estimate for its Koné and Gbongogo Main deposits, at the Company’s flagship Koné project, located in Côte d’Ivoire, where construction continues to rapidly advance on-budget and ahead of schedule with first gold pour anticipated through the oxide circuit in late Fourth Quarter 2026. A total of 174,000 meters of exploration, advance grade control and grade control drilling were conducted in 2025, with 36% directed towards the Koné and Gbongogo Main deposits, in addition to delineating new higher-grade satellite deposits. A total of 59,873 meters of grade control and exploration drilling was completed on the Koné deposit in 2025, increasing the cumulative drilling to 171,050 meters, compared to 100,249 meters prior to the 2024 Updated Feasibility Study. At the Gbongogo Main deposit, 7,292 meters of grade control and exploration drilling have been completed since the beginning of 2025, bringing total drilling to 32,002 meters, compared to 18,276 prior to the 2024 Updated Feasibility Study. The Koné deposit Measured and Indicated Resources increased by 142,000 ounces to 4,630,000 ounces, with grade increasing by 21% to 0.69 g/t Au, while Inferred Resources increased by 749,000 ounces to 1,260,000 ounces, with grade increasing by 21% to 0.52 g/t Au, compared to last year. The Koné deposit maiden Measured Resource of 229,000 ounces at 0.83 g/t Au demonstrates a higher level of resource confidence. At the Gbongogo Main deposit, Indicated Resources increased by 223,000 ounces to 783,000 ounces, with grade increasing by 3% to 1.51 g/t Au, while Inferred Resources increased by 39,000 ounces to 41,000 ounces, with grade increasing by 21% to 1.08 g/t Au, compared to last year. The updated Mineral Resource Estimate for the Koné project’s overall Measured and Indicated Resources increased by 671,000 ounces to 5,880,000 ounces, with grade increasing by 24% to 0.77 g/t Au, while Inferred Resources increased by 782,000 ounces to 1,560,000 ounces, with grade increasing by 7% to 0.58 g/t Au, compared to last year, inclusive of resources for additional satellite deposits published last year. Indicated and Inferred Resources for higher-grade satellite deposits now stand at 1,250,000 ounces at 1.34 g/t Au and 303,000 ounces at 1.07 g/t Au, respectively, highlighting the effectiveness of the exploration programme. Updated resources for satellite deposits, including Gbongogo South, Koban North, ANV, Yere North, Lokolo Main, Sena and Diouma North are expected to be published in the coming weeks, while 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 programme launched in early 2026. Koné project construction continues to rapidly advance on-budget and ahead of schedule with a first gold pour through the oxide circuit anticipated in late Fourth Quarter 2026. The life of mine plan is expected to reflect other value enhancement initiatives such as the addition of the oxide circuit, the process plant design enhancements previously announced, and the previously announced shift to an owner-operated mining model. The updated Mineral Resource Estimate published for the Koné and Gbongogo Main deposits further enhances the quality of the project. The extensive 56,000-meter grade control programme, which represents approximately the first 18 months of production from the Koné deposit and covers a significant portion of oxide mineralisation, further derisks production start-up. The grade control programme, with tighter drill spacing, has delivered significant improvements in the definition of higher-grade shoots, including structures not evident in the broader resource drilling dataset. This has enhanced understanding of grade continuity and will support more accurate production forecasting with improved control over mining dilution. The assayed results have significantly increased confidence in the grade distribution and structural controls of the Koné deposit. The gold mineralisation continuity informs an improved understanding of the mineralisation to support mining activities, whilst also demonstrating the extension potential of the deposit to the southwest, southeast and at depth. Downdip and along strike extensions of the Koné deposit to the southwest, as well as recently identified at-surface oxide mineralisation extensions to the southeast were a focus of further evaluation in 2025. Four diamond drill holes totalling 1,987 meters were drilled in 2025 at a 100-meter spaced grid down to an approximate vertical depth of 300 meters. The purpose was to confirm the downdip continuity of the mineralization to the southwest of the Koné deposit within the diorite. All four diamond drill holes reveal high mineralization potential associated with increased deformation intensity through refolded veins within footwall volcanoclastic units and folded veinlets in diorite. Pervasive hydrothermal breccia zones, characterized by broken textures and strong feldspar and silica alteration, was consistently logged across all holes, indicating robust hydrothermal fluid flows. Observed zones demonstrating higher gold intercepts plot in the continuity of known higher-grade ore shoots controlled by folding axial planes, which are associated with ductile deformation and fluid pathways. The results of the Gbongogo Main Drill Programme have significantly enhanced the grade distribution resolution compared to the Updated Feasibility Study resource data. The transition from a Multiple Indicator Kriging resource estimation model to Ordinary Kriging modelling has improved local estimation accuracy, ensuring accurate geological continuity of individually modelled veins sets. The enhanced geological and resource model will improve controls on mine dilution whilst supporting stronger predictability for production planning. The updated model incorporates a refined interpretation of the ore body geometry, resulting in a resource model that better defines higher grade mineralised zones expecting to improve mine planning, ore selectivity and dilution controls. Updated resources for satellite deposits, including Gbongogo South, Koban North, ANV, Yere North, Lokolo Main, Sena and Diouma North are expected to be published in the coming weeks. Maiden Mineral Resource Estimates for new discoveries, such as Petit Yao and Soman 1 & 2, are expected to be published over the course of 2026.
