<p><strong>關於 Nexa</strong></p>
<p>Nexa 是一家大規模、低成本的綜合多金屬生產商，以鋅為主要產品。我們在拉丁美洲擁有超過 65 年的礦業和冶煉資產開發與運營經驗。我們目前擁有並運營五個多金屬礦山——四個長期地下礦（兩個位於秘魯中央安第斯地區，兩個位於巴西的米納斯吉拉斯州和馬託格羅索州）和一個位於秘魯中央安第斯地區的露天礦。我們還擁有並運營三個鋅冶煉廠——兩個位於巴西米納斯吉拉斯州（特雷斯瑪里亞斯和朱伊斯德福拉），一個位於秘魯利馬（卡哈馬基利亞），後者是美洲最大的鋅冶煉廠。</p>
<p><strong>前瞻性聲明的警示説明</strong></p>
<p>本新聞稿包含某些前瞻性信息和前瞻性聲明，符合適用證券法的定義（統稱為本新聞稿中的&#34;前瞻性聲明&#34;）。本新聞稿中包含的前瞻性聲明可能包括但不限於鋅及其他金屬價格和匯率假設、預計的運營和資本成本、金屬或礦物回收率、礦石品位、礦山壽命、生產率和回報；公司的潛在計劃；對礦藏噸位、品位和含量的估算以及礦產資源和礦藏儲量估算的範圍；生產開始的時間；勘探潛力和結果；未來運營所需許可證的時間和獲取；以及 COVID-19 對我們運營的影響。</p>
<p>這些聲明基於公司當前可獲得的信息，公司不保證實際結果和未來表現及成就將符合或不與管理層或合格人士的預期相差。所有非歷史事實的聲明均為前瞻性聲明。&#34;相信&#34;、&#34;將&#34;、&#34;可能&#34;、&#34;可能有&#34;、&#34;會&#34;、&#34;估計&#34;、&#34;持續&#34;、&#34;預期&#34;、&#34;打算&#34;、&#34;計劃&#34;、&#34;期望&#34;、&#34;預算&#34;、&#34;安排&#34;、&#34;預測&#34;及類似詞語旨在識別估算和前瞻性聲明。前瞻性聲明不是保證，涉及已知和未知的風險、不確定性及其他因素，這些因素可能導致公司的實際結果、表現或成就與前瞻性聲明所表達或暗示的任何未來結果、表現或成就有實質性不同。實際結果和發展可能因多種原因與前瞻性聲明中描述的預期有顯著不同，其中許多因素不在我們的控制之內，包括競爭對手的活動、未來全球經濟形勢、天氣條件、市場價格和條件、匯率以及運營和財務風險。上述事件之一或多個的意外發生可能會顯著改變我們基於其進行估算和前瞻性聲明的運營結果。我們的估算和前瞻性聲明也可能受到法律、政治、環境或其他風險的影響，這些風險可能對項目的潛在開發產生實質性影響，包括與傳染病爆發或健康危機相關的風險，這些風險影響區域或全球的整體經濟活動，以及與地方當局對我們業務和運營的持續或未來調查相關的風險，包括對我們財務報表的影響，涉及任何此類事項的解決。</p>
<p>這些前瞻性聲明與未來事件或未來表現相關，包括當前的估算、預測、預報、信念和關於管理層對公司的業務和運營、礦業生產、我們的增長戰略、適用法律和法規的影響、未來鋅及其他金屬價格、冶煉銷售、資本支出、與勘探和項目評估相關的費用、礦藏儲量和/或礦產資源的估算、礦山壽命和我們的財務流動性等方面的期望。</p>
<p>前瞻性聲明必然基於多個因素和假設，儘管管理層和有資質的人員考慮到他們的經驗認為這些因素和假設是合理和適當的，但本質上仍然存在重大不確定性和偶然性，可能會被證明是錯誤的。關於未來生產成本或產量的聲明基於管理層對運營事項的眾多假設，以及對產品需求按預期發展的假設，客户和其他交易對手履行其合同義務的假設，礦業和冶煉操作的全面整合，運營和資本計劃不會因機械故障、零部件和供應短缺、勞工糾紛、運輸或公用事業中斷、不利天氣條件等問題而受到干擾，以及金屬價格、匯率或能源、供應或運輸成本等方面沒有重大意外變化的假設。</p>
<p>估計和前瞻性聲明僅指作出時的日期，我們不承擔因新信息、未來事件或其他原因而更新或修訂任何估計或前瞻性聲明的義務，除非法律要求。估計和前瞻性聲明涉及風險和不確定性，並不保證未來的表現，因為實際結果或發展可能與前瞻性聲明中描述的預期有實質性差異。有關與這些前瞻性聲明及我們業務相關的風險和不確定性的更多信息，請參閲我們在 SEDAR+（www.sedarplus.ca）和 EDGAR（www.sec.gov）上提交的公開披露文件。</p>

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. Our estimates and forward-looking statements may also be influenced by, among others, legal, political, environmental, or other risks that could materially affect the potential development of the Project, including risks related to outbreaks of contagious diseases or health crises impacting overall economic activity regionally or globally, as well as risks relating to ongoing or future investigations by local authorities with respect to our business and operations and the conduct of our customers, including the impact to our financial statements regarding the resolution of any such matters.</p>
