K92 Mining Announces Strong Q3 Production of 49,776 oz AuEq, Multiple Operational Records and 1 moz AuEq Production Milestone

VANCOUVER, British Columbia, Oct. 08, 2026 (GLOBE NEWSWIRE) — K92 Mining Inc. (“K92” or the “Company”) (TSX: KNT; OTCQX: KNTNF) is pleased to announce production results for the third quarter (“Q3”) of 2026 from its Kainantu Gold Mine in Papua New Guinea.

Q3 2026 Production Results

• Strong quarterly production of 49,776 ounces gold equivalent (“AuEq”)⁽¹⁾ or 46,063 oz gold, 1,948,951 lbs copper and 55,746 oz silver (Figure 1), representing the second-highest quarterly production to date. Quarterly sales of 41,587 oz gold, 1,912,770 lbs copper and 53,575 oz silver. Production is expected to be strongest in Q4, driven by a planned higher-grade stoping sequence and increased mining rates, supported by the continued ramp-up of the second and third mining fronts, which commenced stoping in April and September, respectively, and the completion of multiple key Stage 3 and 4 Expansion enabler projects that improve underground productivity (see “Stage 3 Expansion” below). The Company reiterates its 2026 production guidance of 190,000 to 225,000 oz AuEq (see January 26, 2026 press release).
• Significant production milestone achieved during the quarter – one million AuEq ounces produced since declaring commercial production in February 2018. This milestone highlights the exceptional growth achieved by translating significant exploration success into multiple phases of production expansion through strong operational and project execution.
• Record quarterly ore processed of 250,042 tonnes (Figure 2), an 82% increase from Q3 2025 and an 11% increase from Q2 2026, with a head grade of 6.6 grams per tonne (“g/t”) AuEq, or 6.1 g/t gold, 0.4% copper and 8.5 g/t silver.
• Strong metallurgical recoveries in Q3 of 94.1% for gold and 94.9% for copper (Figure 3), exceeding the updated definitive feasibility study (“Updated DFS”) recovery parameters of 92.6% and 94.2%, respectively (January 1, 2024 effective date), with gold recoveries exceeding the Updated DFS parameter for the 10th consecutive quarter. The new 1.2 million tonnes-per-annum (“tpa”) Stage 3 Expansion Process Plant has continued to perform well since commissioning was completed in December 2025, achieving record monthly throughput of 92,937 tonnes in September 2026 and the year’s second-highest daily throughput of 3,725 tonnes on September 19, 13% above the plant’s design capacity of 3,290 tonnes per day (“tpd”).
• Record quarterly mine development of 3,486 metres, a 41% increase from Q3 2025, including a new monthly development record of 1,220 metres achieved in July. Lateral development rates averaged 1,162 metres per month in Q3, 16% above the Stage 3 Expansion requirement of 1,000 metres per month, with July also exceeding the Stage 4 Expansion requirement of 1,200 metres per month. Further improvements in lateral development rates are expected following completion of commissioning of the Phase 4 Primary Ventilation Upgrade, scheduled for Q4 2026, and the planned arrival of an additional development jumbo in late Q4 to expand the development fleet. The Company is targeting development rates above Stage 4 Expansion requirements in 2027 to further increase operational flexibility.
• Record quarterly total material mined (ore plus waste) of 485,812 tonnes (a 37% increase from Q3 2025 and a 14% increase from Q2 2026), supported by the continued ramp-up of the second mining front and improved material handling following completion of the second material pass and the internal ramp earlier in the year. Recent completion of major haul road and river crossing upgrades, the upcoming completion of commissioning of the Phase 4 Primary Ventilation Upgrade and the ongoing expansion of the Load and Haul fleet are expected to drive further increases in mine physicals (see “Stage 3 Expansion” below).
• Record quarterly ore mined of 252,744 tonnes (a 66% increase from Q3 2025), with mining activity across 14 levels, including the 1010, 1030, 1070, 1090, 1130, 1325, 1345, 1365, 1385 and 1405 levels at Kora, and the 1030, 1050, 1070, 1090, 1110, 1185, 1365, 1385 and 1425 levels at Judd. Long hole stoping performed to design. First stope ore from the third mining front (Twin Incline) was delivered in September, with the operation expected to expand to four mining fronts in 2027.

Stage 3 Expansion – Major Progress on Key Surface and Underground Projects

• As at September 30, 2026, 98% of Stage 3 Expansion growth capital has either been spent or committed, with the expansion remaining on budget.
• During Q3, construction and commissioning activities continued across the key pastefill infrastructure projects:
  • Surface Tailings Filtration Plant – Filtration plant is now operational with production optimization work ongoing.
  • Surface Paste Binder Blending Area and Filter Cake Storage Facility – Structural, mechanical and piping works are complete, with remaining electrical and instrumentation installations progressing toward planned commissioning in early Q4 2026.
  • Underground Paste Plant and Reticulation – On the 1205 level, the silo hopper, feeder, paste and colloidal mixers have been installed. At the 1170 pump chamber, both paste pumps have been installed. All major equipment has now been installed. Remaining civil, structural, mechanical and electrical works are progressing well, together with paste reticulation installation across multiple levels, with commissioning targeted for Q4 2026.
• During the quarter, key Stage 3 Expansion underground infrastructure and operational excellence projects continued to advance, supporting the ongoing mine ramp-up, including:
  • Material Pass System – The second material pass, operational since June, has provided a significant boost to material handling capabilities in the Main Mine and Lower Kora, with dedicated ore and waste passes supporting efficient truck haulage to surface via the Twin Incline. Development of a third material pass is advancing towards targeted completion in Q4 2026, further improving material handling capacity to support the ongoing mine ramp-up.
  • Phase 4 Primary Ventilation Upgrade – Electrification was completed during Q3, with completion of commissioning targeted for the second half of October 2026. The upgrade will increase primary mine airflow capacity from approximately 350 m³/s to 600 m³/s, (expandable to ~700 m³/s), exceeding Stage 4 Expansion and life-of-mine ventilation requirements. This significant increase in primary ventilation capacity is expected to further reduce blast clearance times and enable highly productive one-way or dedicated traffic flow through the Twin Inclines, supporting increased underground material movement and mining rates. To conserve power, the variable speed drive fans will initially operate according to mine demand and ramp up as required.
  • Load, Haul and Development Fleet Expansion – Five new 60-tonne Volvo surface trucks commenced operating in late Q3, with the remaining three trucks expected to arrive in Q4 2026. This fleet will haul directly to the process plant from underground (via the Twin Incline), reducing material rehandling and haul road congestion, and increasing overall haulage capacity. Two replacement Sandvik 45-tonne underground trucks and an additional Sandvik LH621i loader are also expected in Q4 to replace higher hour underground trucks and further expand loader capacity. The LH621i adds to the four new Sandvik LH517i underground loaders brought into operation earlier in 2026, representing a net increase of three loaders following replacement of two high-hour units. An additional development jumbo is also scheduled to arrive in late Q4 to support higher planned lateral development rates in 2027.
• Major surface haul road and river crossing upgrades advanced during the quarter, with the Baupa and Kokomo bridges and Kasese river crossing now complete, tripling payload capacity from 20 tonnes to 60 tonnes. Remaining haul road upgrade works are nearly complete. Together, these improvements are expected to reduce haulage cycle times, support Stage 3 and Stage 4 Expansion throughput requirements and deliver operating cost efficiencies through economies of scale.

Note (1): Gold equivalent production for Q3 2026 is calculated based on: gold $4,308 per ounce; silver $63.89 per ounce; and copper $6.38 per pound. Gold equivalent grade for Q3 incorporates realized recoveries of 94.1% for Au, 94.9% for Cu and 81.3% for Ag.

David Medilek, K92 Chief Executive Officer and Director, stated, “Q3 marked another strong quarter for K92, with production of 49,776 ounces gold equivalent, our second-highest quarterly production result, and multiple quarterly operational records, including lateral development, ore mined, ore processed and total tonnes mined. During the quarter, we also surpassed one million ounces gold equivalent produced since commercial production was declared in February 2018, a significant milestone reflecting the growth achieved by translating significant exploration success into multiple phases of production expansion through strong operational and project execution.

I would like to thank our employees, contractors, local communities, partners and all stakeholders who have contributed to this achievement. In particular, I would like to acknowledge the continued support of Papua New Guinea’s Government, which has been a major factor in our growth and success. As I begin my tenure as CEO, I am proud to celebrate this milestone with our team and recognize John Lewins’ leadership in Kainantu’s growth and development. I look forward to continuing my close working relationship with John in his role as Non-Executive Chair. We will build on this foundation as we continue to execute the Stage 3 and 4 Expansions to deliver our next phase of growth.

Looking ahead, Q4 is expected to deliver a further step forward as the second and third mining fronts continue to ramp up and key infrastructure projects are completed. Commissioning of the Phase 4 Primary Ventilation Upgrade, completion of the remaining haul road ancillary upgrades and continued deployment of the new 60-tonne surface trucks are expected to increase material movement capacity and improve operating flexibility. Together with a planned higher-grade stoping sequence and the continued strong performance of the Stage 3 process plant, these improvements position us for our strongest production quarter of the year and reinforce our confidence in achieving full-year guidance.”
