John Lewins, K92 Chief Executive Officer and Director, stated, “K92 celebrated many achievements
in 2025 in what was a landmark year for the Company as we celebrated our 10 th anniversary and
successfully completed the commissioning of our new 1.2-million tonnes per annum Stage 3 Expansion
processing plant. This coincided with a truly historic milestone for the people of Papua New Guinea,
as the nation celebrated the Golden Jubilee of its independence in 1975.
At the end of 2025, K92 was a major employer in Papua New Guinea, with approximately 2,150
employees and permanent contractors, and temporary contractors and casuals bringing our total
workforce to approximately 3,100. PNG Nationals represented approximately 91% of our operational
workforce, comprising employees and permanent contractors, supported by priority hiring from local
communities. In addition, we have become one of the largest corporate taxpayers among mining
companies in the country, with $139.2M in taxes and royalties paid or accrued in 2025. We are also
currently the largest foreign investor in mineral exploration in Papua New Guinea, with $18M invested
in exploration activities in 2025 and a further $31M to $ 35M planned investment in 2026, well -
positioning the Company for continued growth.
I would like to extend my congratulations to the K92 Mining team and the people of Papua New Guinea
for all the momentous milestones that were achieved during the year. These achievements are a
testament to the dedication and resilience of the innumerable people who have made them possible. As
Papua New Guinea looks to its next chapter, we strongly believe that responsible mining will remain
an important driver of sustainable development for the country and its remarkable people. At K92, we
will continue to work steadfastly in partnership with all our stakeholders to deliver transformational
value for many years to come.”

supporting infrastructure; (ii) statements regarding the expansion of the mine and development of any of the
deposits; (iii) the Kainantu Stage 4 Expansion, operating two standalone process plants, larger surface
infrastructure and mining throughputs; and (iv) the potential extended life of the Kainantu Mine.
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 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”, “would”, “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; fl uctuations 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, Kor a, 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,
4
Israel and Palestine; compliance with various laws and regulatory requirements to which the Company is
subject to, including taxation; the ability to obtain timely financing on reasonable terms when required; the
current and future social, economic and pol itical conditions, including relationship s with the communities in
Papua New Guinea and other jurisdictions it operates; other assumptions and factors generally associated with
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 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 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 actual 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.
