NEWS RELEASE
K92 MINING ANNOUNCES STRONG Q3 PRODUCTION RESULTS – 44,323 OZ AUEQ
PRODUCED PLUS 4,893 OZ AUEQ IN COMMISSIONING STOCKPILE AND
SIGNIFICANT STAGE 3 EXPANSION PROGRESS ACHIEVED
Vancouver, British Columbia, October 8, 2025 - K92 Mining Inc . (“K92” or the “ Company”)
(TSX: KNT; OTCQX: KNTNF) is pleased to announce production results for the third quarter (“Q3”)
of 2025 from its Kainantu Gold Mine in Papua New Guinea.
Q3 2025 Production Results
• Strong quarterly production of 44,323 ounces gold equivalent (“AuEq”) (1) or 42,244 oz
gold, 1,323,538 lbs copper and 34,831 oz silver (Figure 1). Quarterly sales of 45,006 oz
gold, 1,480,151 lbs copper and 43,271 oz silver. With more than 80% of the lower end of
annual guidance achieved in the first three quarters, plus ending Q3 with a 4,893 oz AuEq
commissioning stockpile in line with the Stage 3 Expansion requirements (28,702 tonnes
at 5.3 g/t AuEq or 5.0 g/t gold, 0.24% copper, and 11.9 g/t silver), the Company remains
on track to meet its 2025 production guidance of 160,000–185,000 oz AuEq.
• Quarterly ore processed of 137,172 tonnes, a 31% increase from Q3 2024, with a head
grade of 11.2 grams per tonne (“g/t”) AuEq, or 10.7 g/t gold, 0.47% copper and 1 0.3 g/t
silver. Head grade during the quarter was above budget, benefitting from a positive gold
grade reconciliation versus the latest independent mineral resource estimate (September
12, 2023 effective date for Kora and Judd).
• Strong metallurgical recoveries in Q3 of 95.0% for gold and 94.6% for copper (Figure 2).
The process plant has now delivered six consecutive quarters exceeding the updated
definitive feasibility study (“Updated DFS”) recovery parameters for both gold ( 92.6%)
and copper (94.2%) (January 1, 2024 effective date).
• Record total material mined (ore plus waste) of 353,770 tonnes, with multiple tonnes to
surface daily records (ore plus waste) in late -September, including 5, 769 tonnes on
September 27 and 6,404 tonnes on September 29, demonstrating the increased material
movement benefits realized from the commissioning of the first material pass during the
quarter combined with the commencement of surface trucks operating in the twin incline.
Total mine development was 2,4 77 metres. The operation continues to balance lateral
development priorities between the completion of key underground projects, including
prioritizing low equivalent lateral advance jumbo activities such as the Puma Ventilation
Drive and the underground pastefill chamber.

• Total o re mined of 152,485 tonnes, the second highest on record, with mining activity
across 13 levels, including the 1090, 1110, 1225, 1325, 1345, and 1365 levels at Kora, and
the 1010, 1030, 1050, 1170, 1185, 1325, 1345 and 13 85 levels at Judd – long hole open
stoping performed to design.
Stage 3 Expansion – Significant Progress Made. Construction of Stage 3 Plant Complete,
Commissioning Well-Advanced, First Gold Pour and First Concentrate Production on Track for
First Half of Q4 2025
• Construction of the new 1.2 million tonnes -per-annum Stage 3 Expansion Process Plant
is complete and was delivered under the capital expenditure budget, marking a major
milestone for the construction team. C rushing, grinding and flotation circuits are now
being commissioned with ore , with first gold pour , first gold-copper-silver concentrate
production and completion of plant commissioning on schedule for the first half of Q4
2025. As at September 30, 2025, 90% of Stage 3 Expansion growth capital has either been
spent or committed and remains on budget.
• During Q3, the major construction contracts were awarded for the pastefill plant. The
surface tailings filtration plant detailed engineering and design is complete, early
earthworks are complete and civil works have commenced. The surface storage facility
near the underground mine is rapidly advancing , with site clearing complete, early
earthworks underway, and detailed engineering nearly complete. The underground
pastefill plant bulk excavations made significant progress during the quarter, and detailed
engineering and design is nearly complete. Long -lead items for the various paste
infrastructure projects are now arriving on site. Commissioning remains on schedule to
commence mid-Q1 2026, with practical completion of commissioning of the pastefill
circuit remaining on schedule for mid-2026.
• During the quarter, several key Stage 3 Expansion underground construction and
operational excellence projects were completed or are approaching completion, including:
o Material Pass – Construction and commissioning completed in Q3, connecting the
main mine via gravity to the highly productive twin incline haulage route. In late-
Q3, multiple surface haulage daily records were delivered as noted above, driven
by the commissioning of the material pass, combined with the commencement of
surface haul trucks operating in the twin incline that transport material directly
from underground to surface stockpiles, eliminating the need for rehandle . The
next material pass is planned to commence development in Q4 and become
operational in Q1 2026, enabling a dedicated pass for both ore and waste ,
respectively.
o Phase 2 Ventilation Upgrade – Development of two raisebored ventilation raises
was completed in Q3, with the full ventilation upgrade planned for the second half
of October. This upgrade is expected to deliver a +30% increase in primary mine
airflow (150 m3/s to 200 m 3/s), enabling two major productivity improvements: i)
reduced re-entry times after blasting, and; ii) reduced blast initiation time with the
introduction of a centralized blasting system which enables remote initiation from
3
surface – these two combined improvements will enable firing twice a day
(currently once a day).
o Phase 3 Ventilation Upgrade - Puma Ventilation Drive on schedule for Q4
completion and is now within 70m of surface breakthrough. Surface works are
complete ahead of the breakthrough, and u pon 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. Once complete,
the vent circuit will be modified, so that the twin incline will operate under highly
efficient one-way traffic flow that utilizes both inclines.
o Stage 4 Expansion Ventilation Upgrade – Installation of two x 2 MW variable
speed drive fans is currently underway and scheduled for completion in Q4 .
Electrification is planned to be opportunistically completed in H1 2026 as it is not
required for the Stage 3 Expansion.
o Decline-Incline Convergence Project connecting the Main Mine with the Twin
Incline via internal ramp access – Significant progress was delivered in Q3 with
258 metres of advance achieved, leaving less than 370 metres of development
required for completion. Upon completion scheduled for Q1 2026, this project is
expected to deliver major operational efficienc y improvements as the Main Mine
will now also become accessible by the highly productive twin incline , and all
mining fronts will be connected via an internal ramp, allowing for one-way traffic
flow.
o Surface Tele -Remote Loader System – Completed in Q3, leveraging the
underground fiber optic backbone (Wi-Fi), to enable the operation of underground
loaders from surface. This system maximizes the available operating time over a
24-hour period by enabling tele-remote loading operations during shift change and
re-entry. In late-Q3, the underground fleet was also fully integrated with onboard
Wi-Fi capability to enable real-time data -collection for short interval control
planning, productivity monitoring , and fleet diagnostics to further drive
operational improvements.
o Primary Power Station – Phase 1, 8.8 MW of generation capacity was installed and
commissioned in Q3. Phase 2 has significantly progressed with intended expansion
to 15.2 MW. Long-lead orders have been placed and completion is planned for H1
2026. This will provide standby power during any unexpected outages from the
local grid (hydroelectricity).
• Two new mining fronts have also been significantly developed, including five new
sublevels in the Twin Incline mining front , and two new sublevels in the Lower Kora
mining front , which will facilitate the ramp-up in long -hole stoping over the coming
quarters for the Stage 3 Expansion.

Note (1): Gold equivalent production for Q3 2025 is calculated based on: gold $ 3,507 per
ounce; silver $ 38.71 per ounce; and copper $ 4.49 per pound. Gold equivalent grade for Q 3
incorporates realized recoveries of 95.0% for Au, 94.6% for Cu and 81.3% for Ag.
John Lewins, K92 Chief Executive Officer and Director, stated, “The third quarter marked another
strong period of progress for K92 both in terms of production and continued execution of the Stage 3
Expansion. With the commissioning of the new 1.2 million tonnes -per-annum Stage 3 Expansion
Process Plant nearing completion, this marks an exciting period in the Company’s history as K92
transitions into a Tier-1, mid-tier producer. Notably, ore has already been introduced into the crushing,
grinding, and flotation circuits of the new process plant , keeping us firmly on track for practical
completion of commissioning and the first gold pour and concentrate production in the first half of Q4
2025. Importantly, the team has built the process plant under -budget, representing a significant
achievement.
We are also very pleased with the significant advancement we have made across a multitude of projects,
de-risking the delivery of the Stage 3 Expansion and positioning the underground mine for Stage 4 and
beyond. The recent string of daily records in total tonnes to surface moved (ore + waste) demonstrates
that productivity and efficiency projects are now having a tangible impact on mine performance .
Additionally, critical contracts were awarded, and construction works advanced, for all major pastefill
infrastructure, with commissioning targeted to commence mid-Q1 2026. With 90% of Stage 3 growth
capital already spent or committed, the expansion remains fully funded and on budget.
Having already delivered 80% of the lower end of our annual guidance within the first three quarters
plus a commissioning stockpile of 4,893 oz AuEq at the end of Q3 , we are well-positioned to achieve
our 2025 production guidance.”
