AISC (All-In Sustaining Cost) is a key metric used to understand the cost of a producing mine. It includes mining, processing, site administration and sustaining capital. Our 2026 AISC guidance is US$1,250–$1,350 per oz Au. At current gold prices, this supports a strong margin per ounce. One of the key drivers behind this cost profile is grade. In 2025, we achieved a head grade of 10.3 g/t AuEq, and with an average reserve grade of 8.5 g/t AuEq across our Kora and Judd deposits, less material needs to be processed to produce each ounce, supporting strong margins at current gold levels. 🔗 Full 2026 guidance available in our investor presentation: k92mining.com/investors $KNT $KNTNF

In 2025 we produced a record 174,134 oz AuEq. This reflects the continued advancement of our staged development approach, from Stage 2 and Stage 2A through to Stage 3, where the 1.2 million tonne per annum process plant was commissioned in December and is now ramping up. Our 2026 production guidance is 190,000 to 225,000 oz AuEq. Stage 4 is targeting a run-rate of 400,000+ oz AuEq per annum.

We’re pleased to report our latest high-grade underground drilling results from the Kora and Judd deposits, along with the first results from the Kora & Judd Deeps program at the Kainantu Gold Mine. The results continue to highlight the exceptional continuity, scale, and near-mine growth potential of the Kora–Judd system. Key highlights: 🔸 Near-mine dilatant zone expanded at the Twin Incline mining front, now defined over 100 m of strike and 200 m vertically, and located just ~50 m from development. With pastefill coming online, this zone is expected to support bulk transverse long-hole open stoping, boosting productivity. - 20.50 m at 14.04 g/t AuEq (K2) - 10.70 m at 10.83 g/t AuEq (K2) 🔸 First set of Kora and Judd Deeps drill results delivers significant depth extension, with thick, high-grade mineralization intersected up to 350 m below the Twin Incline and well below the current MRE. Both systems remain open at depth and along strike. 🔸Multiple high-grade zones extended up-dip from the Main Mine at grades outperforming the resource model, including: - 5.45 m at 66.99 g/t AuEq (J1) - 4.95 m at 38.46 g/t AuEq (K1) - 18.19 m at 11.70 g/t AuEq (K2) 🔸 Strong strike extensions to the north and south, including multiple +20 g/t AuEq intercepts and high-grade results recorded towards surface at Judd North. Across the latest 101 underground drill holes completed from Kora-Kora South and Judd-Judd South, all holes intersected mineralization, reinforcing the strength of the system and our resource growth potential. With the 2026 exploration budget increasing by >50% to US$31–35 million and multiple underground and surface rigs active, we see significant potential to continue expanding near-mine resources in the near term. 🔗 Read the full release: loom.ly/Wvrn7sg $KNT $KNTNF #K92Mining #InvestorUpdate

Neglected tropical diseases (NTDs) affect more than a billion people worldwide, disproportionately impacting communities in low- and middle-income countries. These diseases limit access to education, restrict livelihoods, and reinforce cycles of inequality, yet many are preventable and treatable with the right investment and collaboration. World NTD Day is a reminder that health is foundational to opportunity, resilience, and long-term development. Since the 2012 London Declaration, governments, communities, and global partners have continued to work together to drive progress in prevention, treatment, and awareness. At K92, we recognize that strong, healthy communities are essential to sustainable development. Through ongoing health education, outreach, and partnerships in our host communities, we support initiatives that contribute to improved wellbeing and access to care. On World NTD Day, we join the global call to unite, act, and continue working toward the elimination of neglected tropical diseases.

Record Q4 total material mined: 404,205 tonnes. This was supported by the commissioning of the first material pass and the start of surface trucks operating in the Twin Incline, driving major improvements in material movement efficiency.

Inside the Process Plant: Concentrate Thickening & Filtration. This is the final stage in our new process plant flow, where concentrate from flotation is thickened, filtered, and prepared for export. This stage increases the concentrate density, reduces moisture, and ensures a consistent, high-quality product before loading into sea containers for safe, efficient shipment. Key elements include: • 9 m high-rate concentrate thickener, increasing solids to ~68% • High-torque (44,000 Nm) hydraulic rake drive • Jord JJ1200 × 30/50 filter press, producing low-moisture filter cake (~10.5%) Together, these systems support product quality, efficient material handling, and reliable logistics, completing the journey from ore to export-ready concentrate.

CEO John Lewins (Q4 2025 production results): “With the Stage 3 Expansion on budget and approximately 95% of growth capital already spent or committed as at December 31, 2025, supported by a record net-cash position, multiple projects recently completed or nearing completion that are expected to unlock additional significant productivity, and exploration concurrently ramping up, we are well positioned to take another major step forward in 2026.” Read the full release: k92mining.com/news/k92-minin…

We’ve recently achieved a key operational milestone with the successful breakthrough of the internal ramp connecting the Main Mine to the highly productive Twin Incline. This connection brings all mining fronts together through a single internal ramp system, connecting all mining fronts to the highly productive twin incline, to significantly increase operational efficiency across the mine. With the Main Mine now directly accessible via the Twin Incline, this upgrade strengthens the backbone of our underground infrastructure and supports the next phase of productivity as we continue to ramp up mining and processing activities. Another important step forward as we advance Kainantu’s transformation. 📸 A few moments from the recent breakthrough milestone. #K92Mining

As at Dec 31, 2025, ~95% of Stage 3 growth capital has been spent or committed, and the project remains on budget.
