We've released our sixth set of drilling results from Arakompa, highlighting a major expansion of the AR1 high-grade zone and delineation of a substantial near-surface high-grade bulk tonnage zone.

A total of 100 drill holes have now been reported from our maiden surface diamond drill program, with all 33 holes from the latest release intersecting mineralisation. Of these, 40 intersections exceeded 5 g/t AuEq and 20 exceeded 10 g/t AuEq.

Highlights from the latest results:

🔸 Major expansion of the AR1 high-grade zone, now defined up to approximately 400 m of strike and up to 300 m of vertical extent, with a weighted average grade of 9.47 g/t AuEq at an average true width of 4.32 m
🔸 Multiple high-grade intercepts recorded from the AR2 vein system, continuing to demonstrate the strength of mineralisation across the broader corridor
🔸 Significant expansion of a substantial near-surface high-grade bulk tonnage zone, with multiple intersections expanding the zone towards surface, previously interpreted as lower grade due to limited drilling
🔸 Thick, high-grade bulk zone expanded in multiple directions, with increased drill density improving confidence in geological continuity and highlighting potential for grade profile upgrades through both infill and step-out drilling
🔸 Porphyry vector drilling continues to advance, with a ~250 m southern step-out completed and outer potassic alteration intersected in the latest results, providing an important vector towards a potential high-grade potassic core. A second drill rig is now being allocated to the porphyry target and will commence drilling imminently

These results continue to advance Arakompa toward a maiden Mineral Resource Estimate targeted for mid-2026 while demonstrating significant exploration upside across the broader system.

🗣️ John Lewins, CEO and Director:
"Drilling continues to demonstrate a large, near-surface mineralized system, highlighted by the significant expansion and improved continuity of the AR1 high-grade zone and the delineation of a substantial high-grade bulk tonnage zone...Arakompa is increasingly emerging as one of the most significant exploration successes in the Kainantu district in recent years."

Our maiden greenfields exploration program at Wera continues to advance. First announced in September 2025, it has has defined a large 3.5 km by 3.5 km low-sulphidation epithermal gold system, located approximately 10 km southwest of our Kora and Judd deposits.

The system lies within the same major NNE regional mineralized structural corridor that hosts Kora, Judd, and Arakompa and is open along strike in both directions.

Identified from airborne geophysics MobileMT survey and historical data review, the maiden program commenced in July 2024, initially focused on rock chip sampling and trenching, with drilling now underway.

High-grade rock chip samples include: 26.30 g/t Au, 25.06 g/t Au, 23.97 g/t Au, 22.06 g/t Au, 19.69 g/t Au, 19.23 g/t Au, 18.40 g/t Au,18.03 g/t Au, 16.05 g/t Au, and 13.83 g/t Au.

Today we're publishing our seventh Sustainability Report, covering a landmark year for K92 Mining. We marked our 10th anniversary as a Company alongside the Golden Jubilee of Papua New Guinea's independence, and completed commissioning of our new 1.2 million tonnes per annum Stage 3 Expansion processing plant.

The report sets out the full picture of our progress across safety, community, environment, and growth.

Key Highlights:
🔸 918 days without a lost-time injury, a reflection of our strong safety culture
🔸 ~91% of employees and permanent contractors are PNG Nationals
🔸 Zero reportable environmental incidents at the operations
🔸 $161.8M in procurement spend with PNG companies, a 68% increase versus 2024
🔸 $33.1M invested in local Joint Ventures
🔸 $139.2M in taxes and royalties paid or accrued in PNG, a 122% increase from 2024
🔸 Release of our Environmental Policy and Tailings Management Policy, strengthening sustainability governance
🔸 Recognised for the fourth consecutive year by the PNG Chamber of Resources and Energy for community impact with our Adult Literacy Program
🔸 68 tertiary scholarships awarded, with continued investment in PNG skills development and advanced work on the Kainantu Endowment, an independent charitable trust supporting education and long-term opportunity across Papua New Guinea
🔸 Progress on local hydropower improvements and solar farm engineering work, supporting our energy and GHG emissions reduction target

🗣️ Our CEO and Director John Lewins shared:
"I would like to extend my congratulations to the K92 Mining team and the people of Papua New Guinea for all the momentous milestones that were achieved during the year. These achievements are a testament to the dedication and resilience of the innumerable people who have made them possible. As Papua New Guinea looks to its next chapter, we strongly believe that responsible mining will remain an important driver of sustainable development for the country and its remarkable people. At K92, we will continue to work steadfastly in partnership with all our stakeholders to deliver transformational value for many years to come."

Our new 1.2 Mtpa process plant is commissioned and came in under budget, with the broader Stage 3 infrastructure build progressing well.

Swipe to see where ancillary construction stands: the warehouse and Kumian Creek Camp are complete, the Primary Standby Power Station Phase 1 is delivering 10.7 MW power output with Phase 2 expansion progressing to 15.3 MW, and new maintenance facilities are advancing.

A significant number of ancillary packages are complete, supporting the next phase of expansion at Kainantu.

Earlier this year, we achieved a key infrastructure milestone with the connection of the Main Mine’s internal ramp to the Twin Incline, creating what we refer to as “One Mine.”

This links all mining fronts through common infrastructure to the Twin Incline, improving traffic flow, mine flexibility and overall productivity.

With multiple mining fronts now connected and advancing, this milestone helps position K92 for stronger production in the second half of 2026.
