K92 Mining Inc. (KNT:TSX, KNTNF:OTCQX)

Last week, we welcomed analysts and investors to the Kainantu Gold Mine for an in-depth look at the progress underway across our operations, expansions and exploration program. The two-day visit gave attendees the opportunity to meet members of our team and see firsthand how Kainantu is advancing its next phase of growth. Key takeaways included: 🔸 Q3 delivered record quarterly ore processed, ore mined, total material mined and mine development. Three mining fronts are now online, with the second and third fronts ramping up to support increased production. 🔸 Our new 1.2 Mtpa Stage 3 process plant is fully operational and demonstrating strong throughput and recovery performance, with the ability to exceed design parameters. Its modular design also provides a low-capex pathway to Stage 4 throughput of 1.8 Mtpa. 🔸 Major infrastructure upgrades are transforming the operation, including dedicated ore and waste passes, expanded power capacity, upgraded roads and river crossings, 60-tonne surface haulage and the advancing primary ventilation system. 🔸 The transition to pastefill is expected to enable larger, more productive stopes while improving mining flexibility, dilution and ore recovery. 🔸 Exploration continues across our 836.8 km² land package, with active programs advancing Kora, Judd, Arakompa, Maniape, Wera and other high-priority targets. Together, these developments are supporting the Stage 3 ramp-up, advancing the Stage 4 Expansion and strengthening Kainantu’s long-term growth potential. Thank you to everyone who joined us and to the K92 team members who shared their expertise and brought the Kainantu story to life.
