NEWS RELEASE

K92 MINING ANNOUNCES STRONG Q4 PRODUCTION RESULTS – RECORD ANNUAL

PRODUCTION, MULTIPLE OPERATIONAL RECORDS, UPPER END OF PRODUCTION

GUIDANCE ACHIEVED, AND STAGE 3 EXPANSION PROCESS PLANT

COMMISSIONING COMPLETED

Vancouver, British Columbia, January 12, 2026 - K92 Mining Inc . (“K92” or the “Company”)

(TSX: KNT; OTCQX: KNTNF) is pleased to announce production results for the fourth quarter

(“Q4”) of 2025 from its Kainantu Gold Mine in Papua New Guinea.

Q4 2025 Production Results

• Strong quarterly production of 47,178 ounces gold equivalent (“AuEq”) (1) or 44,129 oz

gold, 1,940,781 lbs copper and 47,427 oz silver (Figure 1). Quarterly sales of 41,344 oz

gold, 1,726,051 lbs copper and 44,317 oz silver.

• Record annual production at the upper end of guidance, totaling 174,134 oz AuEq (or

176,995 oz AuEq using 2025 guidance commodity prices of $2,375/oz gold, $28/oz silver

and $4.25/lb copper), comprising 164,484 oz gold, 5,942,203 lbs copper and 159,309 oz

silver, representing a 16% increase from 2024. Annual production was within the

Company’s 2025 guidance range of 160,000 to 185,000 oz AuEq. Record annual sales of

161,100 oz gold, 5,550,751 lbs copper and 154,559 oz silver were also achieved.

• Record quarterly ore processed of 186,198 tonnes (Figure 2), a 93% increase from Q4

2024, with a head grade of 8.0 grams per tonne (“g/t”) AuEq, or 7.4 g/t gold, 0.5% copper

and 10 g/t silver, with a moderate positive gold and copper grade reconciliation versus the

latest independent mineral resource estimate (September 12, 2023 effective date for Kora

and Judd).

• Strong metallurgical recoveries in Q4 of 94.3% for gold and 93.9% for copper (Figure 3),

exceeding the updated definitive feasibility study (“Updated DFS”) recovery parameters

for gold ( 92.6%) and performing in line for copper ( 94.2%) (January 1, 2024 effective

date). The new 1.2 million tonnes -per-annum Stage 3 Expansion Process Plant has

performed well, commissioning was completed in December and, as at the end of October,

all material was processed exclusively through the new plant.

• Record quarterly total material mined (ore plus waste) of 404,205 tonnes, benefitting from

the commissioning of the first material pass in Q3 2025, combined with the

commencement of surface trucks operating in the T win Incline in late Q3 2025. Record

total mine development of 2,787 metres (a 12% increase from Q3 2025), which included a

2

new monthly development record of 1,027 metres achieved in October 2025, supported by

the completion of a number of infrastructure and operational improvement initiatives .

The operation continues to balance lateral development priorities with the completion of

key underground projects, including prioritizing less efficient, lower equivalent lateral

advance jumbo activities, such as the completion of the Puma Ventilation Drive and the

underground pastefill excavations. Importantly, a number of these projects are

approaching completion in Q 1 2026 (as outlined below) which, once delivered , will

increase jumbo availability for operational mine development.

• Record quarterly ore mined of 157,882 tonnes, with mining activity across 15 levels,

including the 1010, 1090, 1110, 1225, 1305, 1325, 1345, 1365, 1385 and 1405 levels at Kora,

the 1185, 1345, 1365, 1385 and 1405 levels at Judd – long hole open stoping performed to

design.

Stage 3 Expansion – Commissioning of Stage 3 Plant Complete and Readily Achieving Design

Targets

• Commissioning and Performance Testing of the new 1.2 million tonnes-per-annum Stage

3 Expansion Process Plant was completed in December, with the plant handed over from

the projects team to the operations team in December. Daily throughput records of 3,822

tonnes and 3,794 tonnes were achieved on December 14 th and 13 th, respectively. As at

December 31, 2025, 95% of Stage 3 Expansion growth capital has either been spent or

committed and remains on budget.

• During Q 4, significant progress was made on key pastefill infrastructure projects

including the underground Pastefill Plant, Surface Tailings Filtration Plant and the

Surface Storage Facility. Concrete works for the filter press structure at the Surface

Tailings Filtration Plant are complete with substantial progress made on the structural

steel erection, mechanical systems , and electrical switchroom installation. Paste Binder

and Filter Cake Storage Facility construction is advancing well, with detailed design and

bulk earthworks complete and civil and concrete works now underway . Significant

progress was made on the underground Pastefill Plant during the quarter with the 1205

Silo Chamber excavation complete and progressive release of excavation areas for

construction scheduled to commence this month. The overall plant design is complete and

the major contracts executed . Long-lead items for the various p astefill infrastructure

projects continue to arrive on site. Progressive commissioning remains on schedule to

commence mid-Q1 2026, with practical completion of commissioning of the pastefill

circuit scheduled for H2 2026.

• During the quarter, several key Stage 3 Expansion underground construction and

operational excellence projects were completed or are approaching completion, including:

o Phase 2 Ventilation Upgrade – Full ventilation upgrade completed in Q4 . This

upgrade has delivered a 30% increase in primary mine airflow (150 m 3/s to 200

m3/s), enabling two major productivity improvement s: i) reduced re- entry times

after blasting, and; ii) reduced blast initiation time with the introduction of the

recently commissioned centralized blasting system which enables remote initiation

from surface.

3

o Phase 3 Ventilation Upgrade – The Puma Ventilation Drive remains on schedule

for completion in Q1 2026 and is now within 15 m of surface breakthrough. Surface

works are complete ahead of the breakthrough, and upon breakthrough, primary

mine airflow is expected to increase to 250 m 3/s, further reducing blast re-entry

times and meeting the airflow requirements for the Stage 3 Expansion.

o Stage 4 Expansion Ventilation Upgrade – Mechanical installation of two 2 MW

variable-speed drive fans was completed in late Q4, with HV electrical works and

associated infrastructure now advancing. Electrification is scheduled for

completion in Q1 2026. On ce commissioned, primary mine airflow capacity is

expected to increase to approximately 600 m³/s (expandable to ~700 m³/s via

benching of the Puma Ventilation Drive), providing ventilation capacity in excess

of requirements for the Stage 4 Expansion and life-of-mine operations. To conserve

power, the fans will initially operate at ~350 m³/s and ramp up incrementally as

required. The completed upgrade will also enable modification of the ventilation

circuit, allowing the T win Incline to operate under a highly efficient one -way

traffic flow utilizing both inclines.

o Decline-Incline Convergence Project connecting the Main Mine w ith the Twin

Incline via internal ramp access – Significant progress was achieved in Q4 with

257 metres of advance completed , leaving less than 50 metres of development

remaining. Upon completion , scheduled for Q1 2026, this project is expected to

deliver major operational efficiency improvements, with the Main Mine becoming

accessible by the highly productive T win Incline, and all mining fronts will be

connected via an internal ramp, allowing for one-way traffic flow.

o Significant Load & Haul age Fleet Expansion Underway – A new Sandvik 517i

loader has recently commenced operation , an additional Sandvik 517i loader is

scheduled to be operational next month , and two more loaders are scheduled to

arrive on site in Q2 2026. This will increase the underground loader fleet by two

units and also replace two high -hour units. The truck fleet is significantly

expanding, with five 30 tonne surface haul trucks having arrived on site in Q3 2025,

plus six new 60 tonne surface trucks scheduled to arrive in H1 2026, and a further

two new 60 tonne surface trucks scheduled to arrive in Q4 2026 – these trucks will

haul from underground in the T win Incline directly to the process plant .

Additionally, two Sandvik TH545i (45 tonne) low-profile underground trucks are

scheduled to arrive on site in Q4 2026, replacing high-hour units. This significant

expansion and replacement of our load and haulage fleet combined with

infrastructure efficiencies via the Twin Incline, Decline- Incline Convergence

Project, ventilation upgrades and material passes will considerably increase our

material movement capabilities.

o Primary Power Station – Phase 1 Power Station Expansion to 10.7 MW prime

power output (increased from 8.8 MW) of generation capacity was installed and

commissioned in Q4. Since commissioning, the site has seen minimal power

4

disruption to both the process plant and underground mine. Phase 2 Power Station

Expansion has progressed significantly, with civil works for the planned expansion

to 15.3 MW prime power output to deliver Stage 4 Expansion power requirements,

now complete. Long-lead orders have been ordered and completion is planned for

Q2 2026. This will provide standby power during any unexpected outages from the

local hydroelectric grid. Installed power capacity is 1.5 MW greater than prime

power output as there has been an allowance made for one generator to be on

standby, supporting continuous load operation and preventative maintenance

programs.

• Two new mining fronts have been substantially developed, including five sublevels on the

Twin Incline mining front and four sublevels on the Lower Kora mining front.

Note (1): Gold equivalent production for Q4 2025 is calculated based on: gold $4,131 per

ounce; silver $ 56.44 per ounce; and copper $5.11 per pound. Gold equivalent grade for Q 4

incorporates realized recoveries of 94.3% for Au, 93.9% for Cu and 82.6% for Ag.

John Lewins, K92 Chief Executive Officer and Director, stated, “We are very pleased with the

performance of the Kainantu Gold Mine in the fourth quarter, closing out a year of significant

achievements for K92. The Company delivered record annual production at the upper half of guidance,

and finished the year strongly, with multiple operational records achieved in the fourth quarter.

During the quarter, we also achieved a major milestone with the successful completion of

commissioning and Performance Testing of the 1.2 million tonnes -per-annum Stage 3 Expansion

Process Plant. First gold pour and concentrate production were delivered in October, with

commissioning completed in December. Plant performance has been strong, with recoveries exceeding

design and multiple daily throughput records achieved well above nameplate, providing a solid

foundation as we continue to optimize performance. The plant was also delivered under budget, which

is a significant achievement for the Company.

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.”
