NEWS RELEASE
K92 MINING ANNOUNCES FILING OF AMENDED TECHNICAL REPORTS FOR
BLUE LAKE MINERAL RESOURCE ESTIMATE AND UPDATED KAINANTU GOLD
MINE DEFINITIVE FEASIBILITY STUDY
Vancouver, British Columbia, March 31, 2025 - K92 Mining Inc. (“K92” or the “Company”)
(TSX: KNT; OTCQX: KNTNF) announces that it has filed amended technical report s (the
“Amended Updated DFS Technical Report ” and the “Amended Blue Lake Technical
Report”) for its Blue Lake Porphyry Deposit (the “ Blue Lake Deposit”) and its Kainantu Gold
Mine Project (the “Kainantu Project”) in Papua New Guinea, as part of a continuous disclosure
review completed by the British Columbia Securities Commission. The Company previously filed
the following technical reports:
• report titled, “Independent Technical Report, Mineral Resource Estimate Blue Lake
Porphyry Deposit, Kainantu, Papua New Guinea” September 20, 2022, with an effective
date of August 1, 2022, prepared by Simon Tear BSc (Hons), EurGeol, PGeo IGI, and
Anthony Woodward BSc (Hons), M.Sc. (the “ September 2022 Blue Lake Technical
Report”); and
• report titled, “Independent Technical Report, Kainantu Gold Mine, Updated Integrated
Development Plan, Kainantu Project, Papua New Guinea” dated November 28, 2024, with
an effective date of January 1, 2024, prepared by Qualified Persons, Andrew Kohler
BAppSc (Geol), PGCert (Geostatistics), MAIG; Simon Tear BSc (Hons), EurGeol, PGeo
(IGI); Brendan Mulvihill MAusIMM (CP Met), RPEQ; Daniel Donald BEng (Hons)
(Mining), MBA, FAusIMM, MSME; Dr. Evan Kirby BSc (Hons), FSAIMM; Isaac Ahmed
P.Eng; Ralph Holding CPEng, FIEAust; and Nicholas Currey MAusIMM (the “November
2024 Kainantu Technical Report”).
The Amended Blue Lake Technical Report supersedes and replaces the September 2022 Blue Lake
Technical Report and reflects the removal of the copper equivalent inferred resource calculation,
and the incorporation of metallurgical recoveries assumptions based on an analogous deposit in
the gold equivalent calculation formula. Given the updated gold equivalent formula and the use of
a gold equivalent cut -off grade, the derived values for the inferred mineral resources have been
updated in the Amended Blue Lake Technical Report.

The November 2024 Kainantu Technical Report included two cases: i) a Stage 3 Expansion
Definitive Feasibility Study (the “DFS Case”) based on Mineral Reserves, and; ii) a separate Stage
4 Expansion Preliminary Economic Assessment (the “ PEA Case ”) that incorporated mineral
resources (measured and indicated, and inferred) from the Kora and Judd deposits. The Amended
Updated DFS Technical Report supersedes and replaces the November 2024 Kainantu Technical
Report and reflects the removal of the PEA Case. The Amended Updated DFS Technical Report
does not modify the DFS Case or any of the mineral resource estimates, mineral reserve estimates,
financial assumptions, or economic analysis contained in the DFS Case. The Company notes that
on December 6, 2022, the Board of Directors of K92 approved the Stage 3 Expansion and Stage 4
Expansion. The Stage 4 Expansion involves operating the Stage 2A Expansion Process Plant (0.6
mtpa as outlined in the DFS Case) and the new standalone Stage 3 Expansion process plant (1.2
mtpa as outlined in the DFS Case), concurrently. The Stage 3 Expansion process plant is currently
under construction and has been designed to be cost effectively expanded beyond 1.2 mtpa through
increasing flotation and filter press capacity.
The Amended Blue Lake T echnical Reports is titled, “Independent Technical Report, Mineral
Resource Estimate Blue Lake Porphyry Deposit, Kainantu, Papua New Guinea” dated March 21,
2025, with an effective date of August 1, 2022.
The Amended Updated DFS Technical Report is titled, “Independent Technical Report, Kainantu
Gold Mine, Updated Definitive Feasibility Study, Kainantu Project, Papua New Guinea” dated
March 21, 2025, with an effective date of January 1, 2024.
The amended technical reports were prepared in accordance with National Instrument 43 -101 -
Standards of Disclosure for Mineral Projects and are available under the Company’s SEDAR +
profile (www.sedarplus.ca), and on the K92 website at www.k92mining.com.
K92 Chief Geologist, Andrew Kohler, MAIG, a Qualified Person under the meaning of National
Instrument 43-101 – Standards of Disclosure for Mineral Projects, has reviewed and is responsible
for the technical content of this news release.

CAUTIONARY STATEMENT REGARDING FORWARD -LOOKING INFORMATION: This news
release includes certain “forward -looking statements” under applicable Canadian securities legislation.
Such forward-looking statements include, without limitation: (i) the results of the Kainantu Mine Definitive
Feasibility Study, including the Stage 3 Expansion, a new standalone 1.2 mtpa process plant and supporting
infrastructure; (ii) statements regarding the expansion of the mine and development of any of the deposits;
(iii) the Kain antu 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, 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, 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 political conditions, including
relationship 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 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.
