NEWS RELEASE

K92 MINING ANNOUNCES STRONG Q2 PRODUCTION RESULTS – 34,816 OZ AUEQ

PRODUCED, AND COMMENCED COMMISSIONING OF 1.2 MTPA STAGE 3 PROCESS

PLANT IN JUNE

Vancouver, British Columbia, July 8, 2025 - K92 Mining Inc. (“K92” or the “Company”) (TSX:

KNT; OTCQX: KNTNF) is pleased to announce production results for the second quarter (“Q2”) of

2025 from its Kainantu Gold Mine in Papua New Guinea.

Q2 2025 Production Results

• Strong quarterly production of 34,816 ounces gold equivalent (“AuEq”) (1) or 32,375 oz

gold, 1,536,505 lbs copper and 42,824 oz silver, representing a 43% increase from Q2 2024.

Quarterly sales of 28,864 oz gold, 1,275,176 lbs copper and 34,532 oz silver. With 82,633

oz AuEq produced during the first six months of 2025, which is ahead of budget, and the

second half forecasted to be the strongest, as outlined in our 2025 Operational Outlook

(see January 23, 2025 press release), the Company re -iterates its annual operational

production guidance of 160,000 to 185,000 oz AuEq.

• Quarterly ore processed of 130,337 tonnes, a 36% and 26% increase from Q2 2024 and

Q1 2025, respectively, with a head grade of 8.9 grams per tonne (“g/t”) AuEq, or 8.3 g/t

gold, 0.55% copper and 12.1 g/t silver.

• Strong metallurgical recoveries in Q2 of 93.3% for gold and 9 4.9% for copper . The

process plant has now delivered four 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).

• Ore mined of 1 33,063 tonnes, with mining activity across 13 levels, including the 1090,

1110, 1305, 1325, 1345, and 1365 levels at Kora, and the 970, 990, 1170, 1325, 1345, 1365

and 1385 levels at Judd – long hole open stoping performed to design . Total material

movements (ore plus waste) totaled 338,696 tonnes and total mine development was 2,466

metres. During the quarter, total material movements were the second highest on record,

even though Stage 3 Expansion electrical commissioning works resulted in a cumulative

5 days of disruptions to the underground, which has largely been resolved.

Stage 3 Expansion – Significant Progress Made. Stage 3 Plant Commissioning Commenced.

• Major milestone achieved in the second half of June, with the commencement of

commissioning of the new 1.2 million tonnes-per-annum Stage 3 Expansion Process Plant.

All pre-commissioning tasks have been completed, and inching of both the SAG and ball

mills was completed in late June. Practical c ompletion of commissioning remains on

schedule for the first half of Q4 2025.

• In June, the Engineering, Procurement, and Construction Management (EPCM) contract

for the pastefill filtration plant and the Engineering, Procurement, and Construction

(EPC) contract for the surface storage facility packages were awarded , with the

underground pastefill plant package self-awarded earlier in the quarter. Commissioning

of all three facilities is scheduled to commence in mid-Q1 2026, while practical completion

of commissioning for the pastefill circuit remains on schedule for mid-2026. As at June

30, 2025, 86% of Stage 3 Expansion growth capital has either been spent or committed

(75% as at March 31, 2025) and remains on budget.

• In Q2, several ancillary construction projects were completed, including: i) the temporary

power station; ii) Phase 1 of the permanent power station, and ; iii) the Kumian Creek

camp accommodation facilities. The 160 ensuite room Kumian Creek Camp is initially

being utilized for construction contractors, then will subsequently be utilized for the Stage

4 Expansion.

• The infrastructure-driven transformation of the underground mine is nearly complete for

the Stage 3 Expansion , with v arious underground construction projects well advanced

and scheduled for completion in Q3, including: i) a fully operational ore/waste pass, ii)

Puma ventilation drive ; and iii) two additional raisebore ventilation raises. In June, the

wifi/fibre optic communications upgrade was completed, enabling the introduction of

various productivity technologies , with the first being the commissioning of surface

operated tele-remote loaders, which commenced in June . Two new mining fronts have

also been significantly developed, including 4 new sublevels in the Twin Incline mining

front and 2 new sublevels in the Lower Kora mining front , with stoping planned to

commence in Q4.

Note (1): Gold equivalent production for Q2 2025 is calculated based on : gold $ 3,299 per

ounce; silver $ 33.41 per ounce; and copper $ 4.31 per pound. Gold equivalent grade for Q 2

incorporates realized recoveries of 93.3% for Au, 94.9% for Cu and 83.7% for Ag.

John Lewins, K92 Chief Executive Officer and Director, stated, “K92 is on the cusp of transforming

into a Tier 1 mid-tier producer, with commissioning of the new 1.2 million tonne s-per-annum Stage 3

Expansion Process Plant now underway. The plant incorporates state -of-the-art processing

technologies and remains on schedule for practical completion of commissioning in the first half of Q4

2025.

Underground infrastructure upgrades are also nearing completion, including a fully operational

ore/waste pass, Puma ventilation drive, and two large -diameter raisebore ventilation raises — key

3

enablers for higher mining rates. Additionally, the recent commencement of commissioning surface-

operated tele -remote loaders marks the first wave of productivity enhancements enabled by our

underground communications upgrade.

Importantly, we are also well-advanced on opening up two new mining fronts in the Twin Incline and

the Lower Kora, which position the mine for higher throughput and an increase in ore tonnes from

lower-cost long-hole stoping. Meanwhile, construction contracts for all major pastefill infrastructure

have been awarded, with commissioning expected to commence in mid-Q1 2026.

Overall we are very pleased with our production performance in the first half of 2025, which is ahead

of budget. With a stronger second half anticipated, driven by higher throughput in Q4, we reiterate our

2025 production guidance.”

All statements in this news release that address events or developments that we expect to occur in the future are

forward-looking statements. Forward -looking statements are statements that are not historical facts and are

generally, although not always, id entified by words such as “expect”, “plan”, “anticipate”, “project”,

“target”, “potential”, “schedule”, “forecast”, “budget”, “estimate”, “intend” or “believe” and similar

expressions or their negative connotations, or that events or conditions “will”, “wo uld”, “may”, “could”,

“should” or “might” occur. All such forward -looking statements are based on the opinions and estimates of

management as of the date such statements are made. Forward -looking statements are necessarily based on

estimates and assumption s that are inherently subject to known and unknown risks, uncertainties and other

factors, many of which are beyond our ability to control, that may cause our actual results, level of activity,

performance or achievements to be materially different from those expressed or implied by such forward-looking

information. Such factors include, without limitation, Public Health Crises, including the epidemic or pandemic

viruses; changes in the price of gold, silver, copper and other metals in the world markets; fluctuations in the

price and availability of infrastructure and energy and other commodities; fluctuations in foreign currency

exchange rates; volatility in price of our common shares; inherent risks associated with the mining industry,

including problems related to weather and climate in remote areas in which certain of the Company’s operations

are located; failure to achieve production, cost and other estimates; risks and uncertainties associated with

exploration and development; uncertainties relating to estimates of mineral resources including uncertainty that

mineral resources may never be converted into mineral reserves; the Company’s ability to carry on current and

future operations, including development and exploration activities at the Arakompa, Kora, Judd and other

projects; the timing, extent, duration and economic viability of such operations, including any mineral resources

or reserves identified thereby; the accuracy and reliability of estimates, projections, forecasts, studies and

assessments; the Company’s ability to meet or achieve estimates, projections and forecasts; the availability and

cost of inputs; the availability and costs of achieving the Stage 3 Expansion or the Stage 4 Expansion; the ability

of the Company to achieve the inputs the price and market for outputs, including gold, silver and copper; failures

of information systems or information security threats; political, economic and other risks associated with the

Company’s foreign operations; geopolitical events and other uncertainties, such as the conflicts in Ukraine,

the mining industry; and the risks, uncertainties and other factors referred to in the Company’s Annual

Information Form under the heading “Risk Factors”.

Estimates of mineral resources are also forward-looking statements because they constitute projections, based

on certain estimates and assumptions, regarding the amount of minerals that may be encountered in the future

and/or the anticipated economics of p roduction. The estimation of mineral resources and mineral reserves is

inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are

not mineral reserves do not have demonstrated economic viability. The accu racy of any such estimates is a

function of the quantity and quality of available data, and of the assumptions made and judgments used in

engineering and geological interpretation, Forward -looking statements are not a guarantee of future

performance, and a ctual results and future events could materially differ from those anticipated in such

statements. Although we have attempted to identify important factors that could cause actual results to differ

materially from those contained in the forward-looking statements, there may be other factors that cause actual

results to differ materially from those that are anticipated, estimated, or intended. There can be no assurance

that such statements will prove to be accurate, as actual results and future events could differ materially from

those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking

statements. The Company disclaims any intention or obligation to update or revise any forward -looking

statements, whether as a result of new information, future events or otherwise, except as required by law.
