<p><strong>前瞻性声明的警示说明</strong></p>
<p>本新闻稿包含某些前瞻性信息和前瞻性声明，符合适用证券法的定义（统称为本新闻稿中的&#34;前瞻性声明&#34;）。本新闻稿中包含的前瞻性声明可能包括但不限于锌及其他金属价格和汇率假设、预计的运营和资本成本、金属或矿物回收率、矿石品位、矿山寿命、生产率和回报；公司的潜在计划；对矿藏吨位、品位和含量的估算以及矿产资源和矿藏储量估算的范围；生产开始的时间；勘探潜力和结果；未来运营所需许可证的时间和获取；以及 COVID-19 对我们运营的影响。</p>
<p>这些声明基于公司当前可获得的信息，公司不保证实际结果和未来表现及成就将符合或不与管理层或合格人士的预期相差。所有非历史事实的声明均为前瞻性声明。&#34;相信&#34;、&#34;将&#34;、&#34;可能&#34;、&#34;可能有&#34;、&#34;会&#34;、&#34;估计&#34;、&#34;持续&#34;、&#34;预期&#34;、&#34;打算&#34;、&#34;计划&#34;、&#34;期望&#34;、&#34;预算&#34;、&#34;安排&#34;、&#34;预测&#34;及类似词语旨在识别估算和前瞻性声明。前瞻性声明不是保证，涉及已知和未知的风险、不确定性及其他因素，这些因素可能导致公司的实际结果、表现或成就与前瞻性声明所表达或暗示的任何未来结果、表现或成就有实质性不同。实际结果和发展可能因多种原因与前瞻性声明中描述的预期有显著不同，其中许多因素不在我们的控制之内，包括竞争对手的活动、未来全球经济形势、天气条件、市场价格和条件、汇率以及运营和财务风险。上述事件之一或多个的意外发生可能会显著改变我们基于其进行估算和前瞻性声明的运营结果。我们的估算和前瞻性声明也可能受到法律、政治、环境或其他风险的影响，这些风险可能对项目的潜在开发产生实质性影响，包括与传染病爆发或健康危机相关的风险，这些风险影响区域或全球的整体经济活动，以及与地方当局对我们业务和运营的持续或未来调查相关的风险，包括对我们财务报表的影响，涉及任何此类事项的解决。</p>

<p>前瞻性声明必然基于多个因素和假设，尽管管理层和有资质的人员考虑到他们的经验认为这些因素和假设是合理和适当的，但本质上仍然存在重大不确定性和偶然性，可能会被证明是错误的。关于未来生产成本或产量的声明基于管理层对运营事项的众多假设，以及对产品需求按预期发展的假设，客户和其他交易对手履行其合同义务的假设，矿业和冶炼操作的全面整合，运营和资本计划不会因机械故障、零部件和供应短缺、劳工纠纷、运输或公用事业中断、不利天气条件等问题而受到干扰，以及金属价格、汇率或能源、供应或运输成本等方面没有重大意外变化的假设。</p>
<p>估计和前瞻性声明仅指作出时的日期，我们不承担因新信息、未来事件或其他原因而更新或修订任何估计或前瞻性声明的义务，除非法律要求。估计和前瞻性声明涉及风险和不确定性，并不保证未来的表现，因为实际结果或发展可能与前瞻性声明中描述的预期有实质性差异。有关与这些前瞻性声明及我们业务相关的风险和不确定性的更多信息，请参阅我们在 SEDAR+（www.sedarplus.ca）和 EDGAR（www.sec.gov）上提交的公开披露文件。</p>
