指示礦產資源估計為 594 千噸，金品位 4.51 克/噸，銀品位 209.7 克/噸，鉛品位 4.34%，鋅品位 6.77%，含 86 千盎司黃金、4.0 百萬盎司銀、57 百萬磅鉛和 89 百萬磅鋅
推測礦產資源估計為 2,736 千噸，金品位 5.07 克/噸，銀品位 188.6 克/噸，鉛品位 3.69%，鋅品位 4.42%，含 446 千盎司黃金、16.6 百萬盎司銀、223 百萬磅鉛和 267 百萬磅鋅
按現貨商品價格計算，約有 7,360 千噸，含 895 千盎司黃金、31 百萬磅銀、407 百萬磅鉛和 678 百萬磅鋅
高品位多金屬資產，指示和推測礦產資源類別的淨冶煉回報分別約為 430 美元/噸和 442 美元/噸。
對 FAD 硫化物材料的兩個冶金複合體的分析表明，鋅濃縮物中存在鎵、銦、銻和錫等關鍵金屬，平均品位分別為 126.0 克/噸鎵、122.5 克/噸銦、324.0 克/噸銻和 759.5 克/噸錫，從冶金和許可的角度提供了進一步的上行潛力。
在地表，物業上的 Gold Hill 目標存在氧化金礦化。

"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 礦產資源更新突顯了礦牀的高品位特性，並支持我們對項目的地質理解，” 地質副總裁 Tyler Hill 表示。“該資源估計僅包括能夠驗證質量控制措施的鑽孔，排除了大量無法驗證控制措施的歷史鑽孔。即使到目前為止完成的鑽孔數量有限，我們通過驗證和整理歷史數據，以及進行的冶金測試工作，顯著增強了該項目。礦牀在深度、東部和北部仍然開放，多個間距較大的歷史鑽孔已交叉到礦化。”

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 先生補充道：“我們相信 FAD 具有顯著的上行潛力，該項目可以通過額外的鑽探獲得相當大的收益，提供對一流礦業管轄區中高品位多金屬礦化的實質性曝光。”

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.

由於其高品位特性和進一步的增長潛力，FAD 提供了重要機會，然而，公司仍然專注於推進其五個核心黃金項目的組合，並翻新 Lone Tree 中央處理設施，這些項目支撐着其發展計劃，旨在創建一個以內華達州為重點的中型黃金生產商。該物業被視為非核心資產，正在考慮出售，以支持公司的再資本化目標。

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.

該項目於 2023 年通過收購 Paycore Minerals Inc.（“Paycore”）獲得，交易金額約為 8800 萬美元，採用全股交易方式。該物業還在 Gold Hill 礦牀附近的地表擁有金氧化礦化（見附錄中的圖 2 和圖 3）。公司進行的初步工作表明，通過在附近設施進行堆浸，可以實現對 Gold Hill 近地表金礦化的貨幣化機會，包括 i-80 Gold 的 Ruby Hill 堆浸設施。

Updated Mineral Resource Estimate

更新的礦產資源估計

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%.

礦產資源估計（“MRE”）在指示類別中擁有 594 千噸礦石，金、銀、鉛和鋅的品位分別為 4.51 克/噸、209.7 克/噸、4.34% 和 6.77%。在推測類別中，有 2,736 千噸，金、銀、鉛和鋅的品位分別為 5.07 克/噸、188.6 克/噸、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 展示了礦牀對商品價格和各種淨冶煉回報（“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 基於 82 個鑽孔，累計長度約為 32,000 米和 4,613 個化驗。這包括 61 個歷史鑽孔，總計約 16,000 米，664 個化驗，以及 21 個鑽孔，總計約 16,000 米，來自 2021 年至 2023 年鑽探項目的 3,949 個化驗。

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).

從 2021 年到 2023 年，Paycore 和 i-80 Gold 完成了 32 個表面反循環和鑽石鑽孔，總計約 22,000 米，化驗樣本 5,460 個。2023 年 i-80 Gold 進行的鑽探樣本結果如下（見 i-80 Gold 於2024年1月25日發佈的新聞稿）。

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).

最近的鑽探項目結果確認了歷史礦化數據，顯示礦化發生在兩個主要區域：與漢堡和埃爾多拉多白雲岩相關的淺層氧化帶，位於歷史採礦區，以及位於埃爾多拉多白雲岩中的深層硫化礦化區（見附錄中的圖 2 至圖 5）。

Project Background

項目背景

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 位於戰鬥山 - 尤里卡趨勢的東南端，與魯比山物業相鄰（見附錄中的圖 1）。公司於 2023 年通過收購 Paycore 獲得 FAD。Paycore 在出售資產給 i-80 Gold 之前，完成了約 11,000 米的鑽探，擴展了礦牀，i-80 Gold 在 2023 年完成了約 10,000 米的鑽探。

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 礦牀在 20 世紀中期由幾位前租賃者進行勘探，其中由 Hecla Mining Company 領導的財團完成了最重要的工作。這項勘探工作包括創建兩個豎井（Locan 和 FAD）以進入礦牀，約 120 個鑽孔和大約 3,000 米的勘探鑽探。

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.

歷史勘探項目包括地表和地下鑽探，並通過從 FAD 豎井開發的巷道收集的通道樣本進行補充，以及約 3,000 米的開發鑽探，其中一些進行了取樣。這項工作發生在大約 20 年的勘探期間，大部分工作在 1948 年至 1963 年之間完成。

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.

該物業由 75 個未專利的礦脈採礦權和 110 個專利礦權組成。物業邊界內約有 1,733 英畝，包括 981 英畝的未專利權、705 英畝的專利礦權和 47 英畝的磨坊場地（見附錄中的圖 5）。公司已修改 2023 年購買的原 FAD 邊界線，以為其相鄰的礦點項目的發展提供靈活性。

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

已知的礦化區主要位於私人專利土地上，現有擾動允許立即進行鑽探。

Metallurgical Testing

冶金測試

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 的初步假設基於預期可以生產和運輸鉛銀和鋅銀濃縮物到多種冶煉選項。初步測試工作表明鉛銀和鋅銀濃縮物是可銷售的。此外，MRE 假設金銀黃鐵礦濃縮物可以在高壓釜設施中處理。這些假設用於開發資源報告的 NSR 值和截止品位。不同濃縮產品的平均回收率總結在表 4 中，由 Blue Coast Research 在 2023 年完成的工作確定。測試工作表明，大部分金礦化報告到黃鐵礦濃縮物的粗礦和精礦尾礦中。值得注意的是，硫化物複合物含有低硅和低有害金屬，增強了未來濃縮物的預期質量潛力。

Table 4: Average Concentrate Recoveries

Concentrates	Gold (%)	Silver (%)	Lead (%)	Zinc (%)

鋅銀濃縮物	-	15.6	4.5	75.7
黃鐵礦金銀濃縮物	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.

未來的工作應包括系統的冶金測試程序，以確認回收假設，評估濃縮物特性，併為經濟研究提供可靠的輸入。這項測試對於降低項目風險和支持向更高級技術研究的推進至關重要。

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，鋅濃縮物中還存在關鍵金屬如鎵和銦，平均品位分別為 126.0 克/噸和 122.5 克/噸，從冶金和許可的角度提供了進一步的潛力。

Geology and Mineralization

地質與礦化

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.

尤里卡地區以金銀鉛鋅多金屬碳酸鹽替代和卡林型金礦牀為特徵，這兩種是該地區的主要礦牀類型。FAD 礦牀是中白堊紀富金碳酸鹽替代礦牀，宿主為中寒武紀的埃爾多拉多白雲岩。形成流體的熱液礦化物質的來源仍然不明，但可能是近端的白堊紀侵入體之一，包括紅寶石山岩體。

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 地產的硫化物替代礦牀主要由等量的黃鐵礦、閃鋅礦和方鉛礦組成，伴有少量的熱液白雲岩、方解石、砷輝礦、天青石、磁黃鐵礦、石英和黃銅礦。在 FAD 的硫化物替代體內，局部發現相對純淨的黃鐵礦、方鉛礦和閃鋅礦小塊，厚度在幾十厘米的範圍內。根據冶金測試，金主要以包裹在黃鐵礦中的形式存在，或以固溶體形式存在於黃鐵礦或砷黃鐵礦中。

Gold Hill Oxide Target

金山氧化物目標

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.

該地產擁有歷史上原始的高品位紅寶石山礦（目前稱為金山）（見附錄中的圖 2、3 和 5）。尤里卡地區在 1866 年至 1964 年間生產了約 1,800,000 噸，估計含有 1,650,000 盎司黃金、39,000,000 盎司白銀和 625 百萬磅鉛 (1)。雖然確切數字未知，但大部分產量來自原始的紅寶石山礦，現在稱為 FAD 地產上的金山。

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 對歷史礦山附近的露天礦潛力進行了鑽探測試。樣本結果 (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/噸金，25.7 克/噸銀，4.3% 鋅和 1.0% 鉛，長度為 28.0 米
2.3 克/噸金，23.8 克/噸銀，4.1% 鋅和 0.4% 鉛，長度為 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，浸出性極佳，在 48 小時氰化瓶滾動測試中金的回收率約為 85%（有關更多細節，請參見2024年6月27日的新聞稿）。金山的氧化物材料可以通過堆浸設施進行處理，包括 i-80 Gold 的紅寶石山堆浸，通過合資或加工安排進行。該地區的鑽探非常有限，系統在延伸方向上仍然開放。

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.

本發佈還包含對礦產資源估算的引用。礦產資源的估算本質上是不確定的，並涉及對許多相關因素的主觀判斷。非礦產儲備的礦產資源沒有證明的經濟可行性。任何此類估算的準確性取決於可用數據的數量和質量，以及在工程和地質解釋中所做的假設和判斷（包括項目的預計未來生產、預計開採的噸位和品位以及預計的回收水平），這些可能被證明是不可靠的，並在某種程度上依賴於鑽探結果的分析和可能最終被證明不準確的統計推斷。礦產資源估算可能需要根據以下因素重新估算：（i）商品價格波動；（ii）鑽探結果；（iii）冶金測試和其他研究；（iv）擬議的採礦操作，包括稀釋；（v）在任何估算日期之後對礦山計劃的評估；以及（vi）可能未能獲得所需的許可證、批准和執照或對現有采礦許可證的變更。
