指示矿产资源估计为 594 千吨，金品位 4.51 克/吨，银品位 209.7 克/吨，铅品位 4.34%，锌品位 6.77%，含 86 千盎司黄金、4.0 百万盎司银、57 百万磅铅和 89 百万磅锌
推测矿产资源估计为 2,736 千吨，金品位 5.07 克/吨，银品位 188.6 克/吨，铅品位 3.69%，锌品位 4.42%，含 446 千盎司黄金、16.6 百万盎司银、223 百万磅铅和 267 百万磅锌
按现货商品价格计算，约有 7,360 千吨，含 895 千盎司黄金、31 百万磅银、407 百万磅铅和 678 百万磅锌
高品位多金属资产，指示和推测矿产资源类别的净冶炼回报分别约为 430 美元/吨和 442 美元/吨。
对 FAD 硫化物材料的两个冶金复合体的分析表明，锌浓缩物中存在镓、铟、锑和锡等关键金属，平均品位分别为 126.0 克/吨镓、122.5 克/吨铟、324.0 克/吨锑和 759.5 克/吨锡，从冶金和许可的角度提供了进一步的上行潜力。
在地表，物业上的 Gold Hill 目标存在氧化金矿化。

"The FAD mineral resource update highlights the high-grade nature of the deposit and supports our geological understanding of the Project," stated Tyler Hill, Vice President of Geology. "This resource estimate only includes drill holes where quality control measures could be validated and excludes a significant number of historical drill holes where control measures could not be verified. Even with a limited number of drill holes completed to-date, we have significantly enhanced the Project through validation and organization of historic data, and through the metallurgical test work conducted. The deposit remains open at depth, to the east and north where several wide-spaced historic holes have intersected mineralization."

“FAD 矿产资源更新突显了矿床的高品位特性，并支持我们对项目的地质理解，” 地质副总裁 Tyler Hill 表示。“该资源估计仅包括能够验证质量控制措施的钻孔，排除了大量无法验证控制措施的历史钻孔。即使到目前为止完成的钻孔数量有限，我们通过验证和整理历史数据，以及进行的冶金测试工作，显著增强了该项目。矿床在深度、东部和北部仍然开放，多个间距较大的历史钻孔已交叉到矿化。”

Mr. Hill added, "We believe FAD has significant upside potential and that the Project could benefit considerably from additional drilling, providing substantial exposure to high-grade polymetallic mineralization in a tier-one mining jurisdiction."

Hill 先生补充道：“我们相信 FAD 具有显著的上行潜力，该项目可以通过额外的钻探获得相当大的收益，提供对一流矿业管辖区中高品位多金属矿化的实质性曝光。”

FAD presents a significant opportunity due to its high-grade nature and further growth potential, however, the Company remains focused on advancing its portfolio of five core gold projects and refurbishing the Lone Tree central processing facility which underpin its development plan to create a Nevada-focused mid-tier gold producer. The Property is considered non-core and is being contemplated for sale in support of the Company's recapitalization objectives.

由于其高品位特性和进一步的增长潜力，FAD 提供了重要机会，然而，公司仍然专注于推进其五个核心黄金项目的组合，并翻新 Lone Tree 中央处理设施，这些项目支撑着其发展计划，旨在创建一个以内华达州为重点的中型黄金生产商。该物业被视为非核心资产，正在考虑出售，以支持公司的再资本化目标。

The Project was acquired in 2023 through the acquisition of Paycore Minerals Inc. ("Paycore") for consideration of approximately US$88 million through an all-share transaction. The Property also hosts gold oxide mineralization near surface at the Gold Hill deposit (see Figures 2 and 3 in the Appendix). Preliminary work conducted by the Company demonstrates opportunity to monetize the near surface gold mineralization at Gold Hill through heap leaching at nearby facilities, including i-80 Gold's Ruby Hill heap leach facility.

该项目于 2023 年通过收购 Paycore Minerals Inc.（“Paycore”）获得，交易金额约为 8800 万美元，采用全股交易方式。该物业还在 Gold Hill 矿床附近的地表拥有金氧化矿化（见附录中的图 2 和图 3）。公司进行的初步工作表明，通过在附近设施进行堆浸，可以实现对 Gold Hill 近地表金矿化的货币化机会，包括 i-80 Gold 的 Ruby Hill 堆浸设施。

Updated Mineral Resource Estimate

更新的矿产资源估计

The mineral resource estimate ("MRE") hosts 594 kt of ore in the indicated category with gold, silver, lead and zinc grades of 4.51 g/t, 209.7 g/t, 4.34%, and 6.77%, respectively. In the inferred category, there are 2,736 kt with respective gold, silver, lead and zinc grades of 5.07 g/t, 188.6 g/t, 3.69%, and 4.42%.

矿产资源估计（“MRE”）在指示类别中拥有 594 千吨矿石，金、银、铅和锌的品位分别为 4.51 克/吨、209.7 克/吨、4.34% 和 6.77%。在推测类别中，有 2,736 千吨，金、银、铅和锌的品位分别为 5.07 克/吨、188.6 克/吨、3.69% 和 4.42%。

Tables 2 and 3 below illustrate the deposit's sensitivity to commodity prices and various net smelter return ("NSR") cut-offs.

下表 2 和表 3 展示了矿床对商品价格和各种净冶炼回报（“NSR”）切割的敏感性。

The MRE is based on 82 drill holes with a cumulative length of approximately 32,000 meters and 4,613 assays. This is comprised of 61 historical holes totaling approximately 16,000 meters with 664 assays, and 21 holes totaling approximately 16,000 meters, with 3,949 assays from the 2021 to 2023 drilling programs.

MRE 基于 82 个钻孔，累计长度约为 32,000 米和 4,613 个化验。这包括 61 个历史钻孔，总计约 16,000 米，664 个化验，以及 21 个钻孔，总计约 16,000 米，来自 2021 年至 2023 年钻探项目的 3,949 个化验。

From 2021 to 2023, Paycore and i-80 Gold completed 32 surface reverse circulation and diamond drill holes, totaling approximately 22,000 meters, with 5,460 assayed samples. Sample results from the 2023 drilling conducted by i-80 Gold are shown below (see i-80 Gold press release dated January 25, 2024).

从 2021 年到 2023 年，Paycore 和 i-80 Gold 完成了 32 个表面反循环和钻石钻孔，总计约 22,000 米，化验样本 5,460 个。2023 年 i-80 Gold 进行的钻探样本结果如下（见 i-80 Gold 于2024年1月25日发布的新闻稿）。

Hole PC23-22: 9.0 g/t Au, 92.4 g/t Ag, 12.2% Zn & 1.0% Pb over 14.6 m
Hole PC23-28: 3.9 g/t Au, 185.6 g/t Ag, 11.1% Zn & 3.6% Pb over 25.4 m, including 4.1 g/t Au,

钻孔 PC23-22:9.0 克/吨黄金，92.4 克/吨银，12.2% 锌和 1.0% 铅，长度 14.6 米
钻孔 PC23-28:3.9 克/吨黄金，185.6 克/吨银，11.1% 锌和 3.6% 铅，长度 25.4 米，其中包括 4.1 克/吨黄金，350.1 克/吨银，13.5% 锌和 7.3% 铅，长度 11.0 米

350.1 g/t Ag, 13.5% Zn & 7.3% Pb over 11.0 m

The results from the most recent drilling programs confirmed the historical data on mineralization, which showed mineralization occurs in two main zones: a shallow oxide zone associated with the Hamburg and Eldorado Dolomite in an area of historic mining, and a deeper sulfide zone of mineralization hosted in the Eldorado Dolomite (see Figures 2 to 5 in the Appendix).

最近的钻探项目结果确认了历史矿化数据，显示矿化发生在两个主要区域：与汉堡和埃尔多拉多白云岩相关的浅层氧化带，位于历史采矿区，以及位于埃尔多拉多白云岩中的深层硫化矿化区（见附录中的图 2 至图 5）。

Project Background

项目背景

FAD is located along the southeastern extent of the Battle Mountain-Eureka Trend and sits contiguous with the Ruby Hill Property (see Figure 1 in the Appendix). The Company acquired FAD in 2023 through the acquisition of Paycore. Paycore completed approximately 11,000 meters of drilling, expanding the deposit, prior to the sale of the asset to i-80 Gold who completed approximately 10,000 meters of drilling during 2023.

FAD 位于战斗山 - 尤里卡趋势的东南端，与鲁比山物业相邻（见附录中的图 1）。公司于 2023 年通过收购 Paycore 获得 FAD。Paycore 在出售资产给 i-80 Gold 之前，完成了约 11,000 米的钻探，扩展了矿床，i-80 Gold 在 2023 年完成了约 10,000 米的钻探。

The FAD deposit was explored by several prior leaseholders in the mid-20th century, with a consortium led by Hecla Mining Company completing the most significant quantity of work. This exploration effort included the creation of two shafts (Locan and FAD) to access the deposit, about 120 borings and approximately 3,000 meters of exploration drilling.

FAD 矿床在 20 世纪中期由几位前租赁者进行勘探，其中由 Hecla Mining Company 领导的财团完成了最重要的工作。这项勘探工作包括创建两个竖井（Locan 和 FAD）以进入矿床，约 120 个钻孔和大约 3,000 米的勘探钻探。

Historical exploration programs included both surface and underground drilling augmented by channel samples collected from drifts developed from the FAD shaft, and approximately 3,000 meters of development drilling, some of which was sampled. This work occurred during an exploration period of approximately 20 years with most of the work completed between 1948 and 1963.

历史勘探项目包括地表和地下钻探，并通过从 FAD 竖井开发的巷道收集的通道样本进行补充，以及约 3,000 米的开发钻探，其中一些进行了取样。这项工作发生在大约 20 年的勘探期间，大部分工作在 1948 年至 1963 年之间完成。

The Property consists of 75 unpatented lode mining claims, and 110 patented mine claims. There are approximately 1,733 acres within the Property boundary, consisting of 981 acres of unpatented claims, 705 acres of patented mine claims, 47 acres at the mills site (see Figure 5 in the Appendix). The Company has modified the original FAD boundary lines purchased in 2023, to provide flexibility for the development of its adjacent Mineral Point project.

该物业由 75 个未专利的矿脉采矿权和 110 个专利矿权组成。物业边界内约有 1,733 英亩，包括 981 英亩的未专利权、705 英亩的专利矿权和 47 英亩的磨坊场地（见附录中的图 5）。公司已修改 2023 年购买的原 FAD 边界线，以为其相邻的矿点项目的发展提供灵活性。

Known mineralized zones on the Property are mostly contained within private patented land with existing disturbance which allows for immediate drilling to take place.

已知的矿化区主要位于私人专利土地上，现有扰动允许立即进行钻探。

Metallurgical Testing

冶金测试

Preliminary assumptions for the MRE are based on the expectation that lead-silver and zinc-silver concentrates can be produced and shipped to a variety of smelter options. Preliminary test work indicates the lead-silver and zinc-silver concentrates are salable. Further, the MRE assumes a gold-silver pyrite concentrate can be processed at an autoclave facility. These assumptions were used to develop NSR values and cut-off grades for resource reporting. The average recoveries for the different concentrate products derived from the mineralized material are summarized in Table 4 and were determined by work completed by Blue Coast Research in 2023. Test work indicates that the majority of the gold mineralization reports to the rougher and cleaner tails in pyrite concentrate. Notably, the sulfide composites contain low silica and low deleterious metals, enhancing the expected quality potential of future concentrates.

MRE 的初步假设基于预期可以生产和运输铅银和锌银浓缩物到多种冶炼选项。初步测试工作表明铅银和锌银浓缩物是可销售的。此外，MRE 假设金银黄铁矿浓缩物可以在高压釜设施中处理。这些假设用于开发资源报告的 NSR 值和截止品位。不同浓缩产品的平均回收率总结在表 4 中，由 Blue Coast Research 在 2023 年完成的工作确定。测试工作表明，大部分金矿化报告到黄铁矿浓缩物的粗矿和精矿尾矿中。值得注意的是，硫化物复合物含有低硅和低有害金属，增强了未来浓缩物的预期质量潜力。

Table 4: Average Concentrate Recoveries

锌银浓缩物	-	15.6	4.5	75.7
黄铁矿金银浓缩物	80.0	5.0	-	-

Future work should include systematic metallurgical test programs to confirm recovery assumptions, evaluate concentrate characteristics, and provide reliable inputs for economic studies. This testing will be essential to de-risk the Project and support advancement toward more advanced technical studies.

未来的工作应包括系统的冶金测试程序，以确认回收假设，评估浓缩物特性，并为经济研究提供可靠的输入。这项测试对于降低项目风险和支持向更高级技术研究的推进至关重要。

Additionally, critical metals such as gallium and indium are present in the zinc concentrate, with average grades of 126.0 g/t and 122.5 g/t, respectively, providing further upside from a metallurgical and permitting standpoint.

此外，锌浓缩物中还存在关键金属如镓和铟，平均品位分别为 126.0 克/吨和 122.5 克/吨，从冶金和许可的角度提供了进一步的潜力。

Geology and Mineralization

地质与矿化

The Eureka district is characterized by gold-silver-lead-zinc polymetallic carbonate replacement and Carlin-type gold deposits, which are the two primary deposit-types within the district. The FAD deposit is a mid-Cretaceous gold-rich carbonate replacement deposit and is hosted by the Eldorado dolomite of middle Cambrian age. The source of hydrothermal mineralized material forming fluids remains enigmatic, but may be one of the proximal Cretaceous intrusions, including the Ruby Hill stock.

尤里卡地区以金银铅锌多金属碳酸盐替代和卡林型金矿床为特征，这两种是该地区的主要矿床类型。FAD 矿床是中白垩纪富金碳酸盐替代矿床，宿主为中寒武纪的埃尔多拉多白云岩。形成流体的热液矿化物质的来源仍然不明，但可能是近端的白垩纪侵入体之一，包括红宝石山岩体。

Sulfide replacement deposit on the FAD property consists mainly of subequal amounts of pyrite, sphalerite, and galena, with subordinate amounts of hydrothermal dolomite, calcite, arsenopyrite, tennantite, pyrrhotite, quartz, and chalcopyrite. Locally, relatively pure pods of pyrite, galena, and sphalerite are found with thicknesses in the range of tens of centimeters within sulfide replacement masses at FAD. Gold occurs mostly as inclusions in pyrite or in a solid solution in pyrite or arsenian pyrite, based on metallurgical tests.

FAD 地产的硫化物替代矿床主要由等量的黄铁矿、闪锌矿和方铅矿组成，伴有少量的热液白云岩、方解石、砷辉矿、天青石、磁黄铁矿、石英和黄铜矿。在 FAD 的硫化物替代体内，局部发现相对纯净的黄铁矿、方铅矿和闪锌矿小块，厚度在几十厘米的范围内。根据冶金测试，金主要以包裹在黄铁矿中的形式存在，或以固溶体形式存在于黄铁矿或砷黄铁矿中。

Gold Hill Oxide Target

金山氧化物目标

The Property hosts the historic original high-grade Ruby Hill mine (currently Gold Hill) (see Figures 2, 3, and 5 in the Appendix). The Eureka district produced an estimated 1,800,000 tonnes from 1866 through 1964 and is estimated to have contained 1,650,000 ounces of gold, 39,000,000 ounces of silver, and 625 million pounds of lead(1). Although the exact figures are unknown, the majority of this production came from the original Ruby Hill mine, now known as Gold Hill on the FAD property.

该地产拥有历史上原始的高品位红宝石山矿（目前称为金山）（见附录中的图 2、3 和 5）。尤里卡地区在 1866 年至 1964 年间生产了约 1,800,000 吨，估计含有 1,650,000 盎司黄金、39,000,000 盎司白银和 625 百万磅铅 (1)。虽然确切数字未知，但大部分产量来自原始的红宝石山矿，现在称为 FAD 地产上的金山。

In 2022, Paycore drill tested the potential for an open pit mine in the vicinity of the historic mine. Sample results(2) include:

在 2022 年，Paycore 对历史矿山附近的露天矿潜力进行了钻探测试。样本结果 (2) 包括：

1.0 g/t Au, 25.7 g/t Ag, 4.3% Zn & 1.0% Pb over 28.0 m
2.3 g/t Au, 23.8 g/t Ag, 4.1% Zn & 0.4% Pb over 23.9 m

1.0 克/吨金，25.7 克/吨银，4.3% 锌和 1.0% 铅，长度为 28.0 米
2.3 克/吨金，23.8 克/吨银，4.1% 锌和 0.4% 铅，长度为 23.9 米

Initial metallurgical work indicated excellent leachability with gold recoveries of approximately 85% in 48-hour cyanidation bottle roll tests (see press release dated June 27, 2024 for additional detail). Oxide material from Gold Hill could be processed at nearly by heap leaching facilities, including i-80 Gold's Ruby Hill heap leach through a joint venture or tolling arrangement. Very limited drilling has been conducted in this area, and the system remains open on strike.

初步冶金工作表明，浸出性极佳，在 48 小时氰化瓶滚动测试中金的回收率约为 85%（有关更多细节，请参见2024年6月27日的新闻稿）。金山的氧化物材料可以通过堆浸设施进行处理，包括 i-80 Gold 的红宝石山堆浸，通过合资或加工安排进行。该地区的钻探非常有限，系统在延伸方向上仍然开放。

本新闻稿中列出的某些信息，包括但不限于关于项目矿产资源估算结果的声明、管理层对公司未来计划和运营的评估、项目或矿床的潜在价值、公司发展计划的影响和预期时间、公司钻探计划的时间、执行和结果的预期、公司是否能够成功出售项目、项目的增长潜力、FAD 矿产资源的潜力、生产的预期时间、冶金测试、项目开发或技术研究，构成适用证券法意义上的前瞻性声明或前瞻性信息。所有非历史事实的声明均为前瞻性声明。通常，但并非总是，前瞻性声明可以通过使用 “计划”、“预期”、“预计”、“预算”、“安排”、“估计”、“持续”、“预测”、“项目”、“预测”、“意图”、“预期” 或 “相信” 等词语，或这些词语和短语的变体或否定形式来识别，或表明某些行动、事件或结果 “可能”、“可以”、“将”、“应该”、“可能” 或 “将” 被采取、发生或实现。读者应注意，尽管在准备信息时所使用的假设被认为是合理的，但可能会被证明是不准确的，因此不应依赖前瞻性声明。公司的实际结果、表现或成就可能与这些前瞻性声明中表达或暗示的结果有重大差异，因此，无法保证前瞻性声明所预期的任何事件将会发生，或者如果发生，公司的收益将是什么。由于其性质，前瞻性声明受到许多风险和不确定性的影响，其中一些超出了公司的控制，包括一般经济和行业状况、商品价格波动、产权风险和不确定性、地质、冶金和岩土研究及意见的不确定性，以及从内部和外部来源（如出售资产、重组债务或以可能苛刻或高度稀释的条款获得额外股本）获得足够资本的能力。公司的再融资能力将取决于资本市场及其当时的财务状况、货币波动、建设和运营风险、许可和许可证要求、环境风险、来自其他行业参与者的竞争、合格人员或管理人员的缺乏、矿产资源或生产估算的不准确性。

This release also contains references to estimates of mineral resources. The estimation of mineral resources 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 (including estimated future production from the Project, the anticipated tonnages and grades that will be mined and the estimated level of recovery that will be realized), which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral resource estimates may have to be re-estimated based on: (i) fluctuations in commodities prices; (ii) results of drilling, (iii) metallurgical testing and other studies; (iv) proposed mining operations, including dilution; (v) the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licenses or changes to existing mining licenses.

本发布还包含对矿产资源估算的引用。矿产资源的估算本质上是不确定的，并涉及对许多相关因素的主观判断。非矿产储备的矿产资源没有证明的经济可行性。任何此类估算的准确性取决于可用数据的数量和质量，以及在工程和地质解释中所做的假设和判断（包括项目的预计未来生产、预计开采的吨位和品位以及预计的回收水平），这些可能被证明是不可靠的，并在某种程度上依赖于钻探结果的分析和可能最终被证明不准确的统计推断。矿产资源估算可能需要根据以下因素重新估算：（i）商品价格波动；（ii）钻探结果；（iii）冶金测试和其他研究；（iv）拟议的采矿操作，包括稀释；（v）在任何估算日期之后对矿山计划的评估；以及（vi）可能未能获得所需的许可证、批准和执照或对现有采矿许可证的变更。
