CLOSING OF OTAVI PROJECT SALE<BR>
TO MIDNAB RESOURCES</P>

<P STYLE="font: 10pt/115% Verdana, Helvetica, Sans-Serif; margin: 0 0 6pt; text-align: justify"><B>Luxembourg, December 22, 2025</B> -
Nexa Resources S.A. (&#8220;Nexa Resources&#8221;, &#8220;Nexa&#8221; or the &#8220;Company&#8221;) (NYSE Symbol: &#8220;NEXA&#8221;)
announces today the completion of the previously disclosed sale (the &#8220;Transaction&#8221;) of ten Exclusive Prospecting Licenses
(&#8220;EPLs&#8221;) forming part of the Otavi and Namibia North projects (the &#8220;Project&#8221;) by its subsidiary, Votorantim Metals
Namibia (Pty) Ltd., to Midnab Resources (Pty) Ltd. (&#8220;Midnab&#8221;), a subsidiary of Midas Minerals Ltd. (ASX Symbol: MM1). The
Project was previously part of a joint venture between Nexa Recursos Minerais S.A. (&#8220;Nexa Brazil&#8221;) and the Japan Organization
for Metals and Energy Security (&#8220;JOGMEC&#8221;), a Japanese state-owned enterprise. JOGMEC retains rights to 49% of the proceeds
from this sale.</P>

<P STYLE="font: 10pt/115% Verdana, Helvetica, Sans-Serif; margin: 0 0 6pt; text-align: justify">Under the terms of the definitive agreement,
all EPLs have been sold and transferred, as well as related rights, titles, and interests in the Project to Midnab. The Transaction was
completed following the fulfillment of all closing conditions.</P>

<P STYLE="font: 10pt/115% Verdana, Helvetica, Sans-Serif; margin: 0 0 6pt; text-align: justify">As previously disclosed, Nexa continues
to evaluate risk-return alternatives across its portfolio. This divestment marked another step in the Company&#8217;s ongoing portfolio
optimization strategy, which focuses on prioritizing return-generating assets, enhancing free cash flow, and supporting a disciplined
capital allocation framework. Namibia remains a strategic region for Nexa as the Company advances its copper exploration initiatives beyond
Latin America.</P>

<P STYLE="font: 9.5pt/107% Verdana, Helvetica, Sans-Serif; margin: 12pt 0 6pt; color: #ED7D31"><B>About Midnab Resources (Pty) Ltd.</B></P>

<P STYLE="font: 10pt/107% Verdana, Helvetica, Sans-Serif; margin: 0 0 6pt; text-align: justify">Midnab Resources (Pty) Ltd is a wholly
owned subsidiary of Midas Minerals Limited, a mineral exploration company listed on the Australian Securities Exchange with a primary
focus on precious and base metals. Midas&#8217; Board and management have a strong track record of delivering value for stakeholders through
world-class mineral discoveries and mine development in Africa and Australia.</P>

<P STYLE="font: 9.5pt/107% Verdana, Helvetica, Sans-Serif; margin: 12pt 0 6pt; color: #ED7D31"><B>About Nexa</B></P>

<P STYLE="font: 10pt/107% Verdana, Helvetica, Sans-Serif; margin: 0 0 6pt; text-align: justify">Nexa is a large-scale, low-cost, integrated
polymetallic producer, with zinc as our main product. We have over 65 years of experience developing and operating mining and smelting
assets in Latin America. Nexa currently owns and operates five polymetallic mines &#8211; four long-life underground (two in the Central
Andes region of Peru and two in Brazil, in the state of Minas Gerais and Mato Grosso), and one open-pit in Peru. Nexa also owns and operates
three smelters: two in Minas Gerais, Brazil (Tr&ecirc;s Marias and Juiz de Fora), and one in Lima, Peru (Cajamarquilla), which is the
largest smelter in the Americas.</P>

<P STYLE="font: 10pt/107% Verdana, Helvetica, Sans-Serif; margin: 0 0 6pt; text-align: justify">Nexa was among the top five producers
of mined zinc globally in 2024 and one of the top five metallic zinc producers worldwide in 2024, according to Wood Mackenzie.</P>

information and forward-looking statements as defined in applicable securities laws (collectively referred to in this news release as
&#8220;forward-looking statements&#8221;). All statements other than statements of historical fact are forward-looking statements. The
words &#8220;believe,&#8221; &#8220;will,&#8221; &#8220;may,&#8221; &#8220;may have,&#8221; &#8220;would,&#8221; &#8220;estimate,&#8221;

Forward-looking statements are not guarantees and involve known and unknown risks, uncertainties and other factors which may cause the
actual results, performance or achievements of Nexa to be materially different from any future results, performance or achievements expressed
or implied by the forward-looking statements. Actual results and developments may be substantially different from the expectations described
in the forward-looking statements for a number of reasons, many of which are not under our control, among them, the activities of our
competition, the future global economic situation, weather conditions, market prices and conditions, exchange rates, and operational
and financial risks. The unexpected occurrence of one or more of the abovementioned events may significantly change the results of our
operations on which we have based our estimates and forward-looking statements.</P>

of our projects, including risks related to outbreaks of contagious diseases or health crises impacting overall economic activity regionally

based upon a number of factors and assumptions that, while considered reasonable and appropriate by management and qualified persons considering
their experience are inherently subject to significant uncertainties and contingencies and may prove to be incorrect. Statements concerning
future production costs or volumes are based on numerous assumptions of management regarding operating matters and on assumptions that
demand for products develops as anticipated, that customers and other counterparties perform their contractual obligations, full integration
of mining and smelting operations, that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability
of parts and supplies, labor disturbances, interruption in transportation or utilities, adverse weather conditions, and that there are
no material unanticipated variations in metal prices, exchange rates, or the cost of energy, supplies or transportation, among other assumptions.</P>
