Vancouver, British Columbia, January 10, 2023 - K92 Mining Inc. (“K92” or the “Company”)
(TSX: KNT; OTCQX: KNTNF) announces production results for the fourth quarter (“Q4”) of
2022 at its Kainantu Gold Mine in Papua New Guinea , of 35,538 oz AuEq or 31,204 oz gold,
1,827,085 lbs copper and 40,517 oz silver. Annual production achieved a record of 122,806 oz
AuEq or 107,546 oz gold, 6,247,950 lbs copper and 126,043 oz silver, achieving the guidance
range of 115,000 to 140,000 oz AuEq and increasing 18% year over year. Sales during the fourth
quarter were 35,212 oz gold, 1,923,116 lbs copper and 44,828 oz silver. Annual sales were 110,654
oz gold, 6,072,879 lbs copper and 125,155 oz silver.
During the fourth quarter, the process plant delivered record quarterly ore processed of 121,686
tonnes or 1,323 tpd, an increase of 22% from Q4 2021. On an annual basis, a record 448 kt of ore
was processed, increasing 33% from 2021. Importantly, in November, the process plant achieved
record monthly throughput of 1,382 tpd, greater than the Stage 2A Expansion run-rate of 1,370
tpd. The strong throughput is especially significant as the final Stage 2A Expansion plant upgrade
is not yet complete, with the flotation expansion that will double rougher capacity expected to be
commissioned in Q1 2023.
The flotation expansion is expected to provide a boost to metallurgical recoveries and provide
flexibility to potentially increase throughput further and beyond the Stage 2A design -run rate
(500,000 tpa / 1,370 tpd ). The new filter press and TC -1000 secondary/tertiary crusher for Stage
2A are installed and operational.
Mine performance during the fourth quarter recorded 111,448 tonnes of ore mined, and delivered
a total material mined (ore plus waste) record of 287,446 tonnes mined, representing an increase
of 28% from Q4 2021. On an annual basis, material movements of 448 kt of ore mined and 994 kt
of total material mined both achieved records, increasing 40% and 25% from 2021, respectively.
During the quarter, long hole stoping continued to perform to the design, with operations focused
on Kora’s K1 and K2 veins, and Judd’s J1 Vein for a total of 11 levels mined. Mining on Kora
was conducted on the 1130, 1150, 1170, 1205, 1245, 1265 and 1285 levels, and Judd on the 1235,
1265, 1285 and 1305 levels.
The operation delivered head grades of 8.75 g/t gold, 0.74% copper and 13.31 g/t silver (9.98 g/t
AuEq) in Q4. Metallurgical recoveries averaged 91.2% for gold and 91.8% for copper during the
quarter, with recoveries expected to improve upon the commissioning of the flotation expansion
in Q1 2023.
Record mine development advance was achieved in the fourth quarter, of 2,221 metres (including
the twin incline), a 45% increase from Q4 2021. Twin incline development advance also made
significant progress, exceeding the budget by 76% during the quarter and by 52% during 2022. As
of December 31, 2022, incline #2 (6m x 6.5m) advanced to 1,843 metres and #3 (5m x 5.5m)
advanced to 1,811 metres. On an annual basis, record overall underground development of 7.5 km
was achieved, a 31% increase from 2021.

COVID-19 Operational Resiliency
The Kainantu Gold Mine operates under a comprehensive COVID -19 Management Plan that has
continuously operated during the pandemic. A considerable focus is on health and safety and risk-
mitigation. Under the COVID -19 Management Plan, K92 has: established a Government -
recognized testing lab facility utilizing qualified medical personnel on site; set up quarantine and
isolation facilities for incoming staff (currently not in use); and implemented enhanced hygiene,
disinfecting and training systems and procedures. A focus has been towards supporting
Government efforts at a national, provincial and local level through the 1.5 m illion PGK (Papua
New Guinea Kina) COVID -19 Assistance Fund , and a further 1.0 million PGK of additional
assistance funding to Eastern Highlands Province.
In addition to its various control measures, K92 continues to make considerable progress
increasing resiliency through vaccinations of our expatriate and PNG national workforce, with
vaccinations continuing to be administered on site. Over 75% of our workforce (employees and
contractors) have received at least one vaccine dose. The Company is in close communications
with the provincial and national health authorities of Papua New Guinea and the Government of
Australia in addition to the Papua N ew Guinea Chamber of Mines and Petroleum to deliver an
effective pandemic response.

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. Once again, Kainantu achieved
multiple operational records, delivering record mill throughput, total mined material, and
underground development rates. Quarterly pro duction was the second highest on record, with
4
35,538 oz AuEq produced and on an annual basis we confidently achieved our production
guidance.
The performance of the process plant has been a major positive. During the quarter, another new
daily throughput record of 1,714 tonnes processed was achieved and on a monthly basis, Stage 2A
Expansion throughput rates of 1,370 tpd have already been achieved ahead of the flotation
expansion, the last major upgrade of the Stage 2A Expansion. The flotation expansion which will
double rougher capacity , is now planned to be commissioned in Q1 2023, and is expected to
provide a boost to not only recoveries but also plant flexibility, with the potential to ultimately
exceed the Stage 2A Expansion run-rate.
In the mine, Kainantu delivered record material mined of 287 kt and record development advance
of 2,221 metres, representing a 28% and 45% increase from Q4 2021, respectively. Development,
as noted in previous press releases, is a major focus going forward as we open up the mine ahead
of the Stage 3 and Stage 4 Expansion s while also boosting our immediate mine operational
flexibility. I am pleased to report that quarter over quarter, development advance increased 18%
in Q4 . The strong increase has be en driven by a combination of a new replacement jumbo ,
improvements in ventilation, haulage, drill and blast , plus improvements to maintenance and
servicing, benefiting from the recently constructed new equipment workshop. We expect
development advance to continue to increase through 2023, as new equipment arrives and the
development cycle continues to be optimized.
As we look at 2023, we have tremendous excitement about our exploration programs. The number
of drills will be ramping up from 11 to 13 and our focus is on resource growth . Surface drilling
plans to focus on Kora South, Judd South, Judd and the A1 Porphyry, with underground drilling
focusing on Kora, Kora South, Judd, Judd South and Northern Deeps. The strong development
advance from our southern drill drive and twin incline is also opening up new prospective drilling
horizons.”

Expansion, operating two standalone process plants, larger surface infrastructure and mining throughputs.
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, identified by words such a s “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”, “would”,
“may”, “could”, “s hould” 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 assumptions that are inherently su bject 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 COVID-19 Pandemic; changes in the price of gold, silver, copper and other
metals in the world markets; fluctuations in the price and availab ility 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 re mote 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; 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; inability of the Company to
identify appropriate acquisition targets or complete desirable acquisitions; failures of information systems
or information security threats; political, economic and other risks associated with the Company’s foreign

other jurisdictions it operates; other assumptions and factors generally associated with the mining
industry; and the risks, unce rtainties 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 production. 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 accuracy 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 a s a result of new information,
future events or otherwise, except as required by law.
