Sarama Resources Reports Significant Increase in Mineral Resources at The Sanutura Project

Accesswire ·  2021/11/16 21:41

VANCOUVER, BC / ACCESSWIRE / November 16, 2021 / Sarama Resources Ltd. (" Sarama " or the " Company ") is pleased to announce a significant increase in mineral resources for its 100%-owned (12) Sanutura Project (the " Project ") in south-west Burkina Faso. This follows an updated interpretation and re-estimation of mineral resources at the Bondi Deposit, located to the north of the Project's main Tankoro Deposit.

不列顛哥倫比亞省溫哥華/ACCESSWIRE/2021 年 11 月 16 日/ 薩拉瑪資源有限公司 (” 薩拉馬 “或者” 公司 “) 很高興地宣佈,其 100% 持有的礦產資源大幅增加 (12) Sanutura 項目(” 項目 “) 在布基納法索西南部。在此之前,對位於該項目主要坦科羅礦牀以北的邦迪礦牀的礦產資源進行了最新的解釋和重新估計。

The Sanutura Project is an advanced-stage exploration project covering approximately 1,500km² (refer Figure 1) that hosts a significant, well-defined mineral resource base and a suite of exploration targets.

Sanutura項目是一個後期勘探項目,佔地約1,500平方公里(參見圖1),擁有重要的、明確的礦產資源基礎和一系列勘探目標。

The updated mineral resource estimate at the Project (refer Table 1) now stands at:

該項目的最新礦產資源估算(參見表1)現在爲:

  • 9.4Mt @ 1.9g/t Au for 0.6Moz gold (Indicated); plus
  • 52.7Mt @ 1.4g/t Au for 2.3Moz gold (Inferred) (1) .
  • 9.4Mt @ 1.9g/t Au 爲了 0.6Moz 黃金(已標示);加
  • 52.7Mt @ 1.4g/t Au 爲了 2.3Moz 黃金(推斷) (1)

This represents a significant increase over the 2020 mineral resource estimate of 0.6Moz Au (Indicated) and 1.9Moz Au (Inferred) (2) (refer Appendix B) and highlights the scale of the Project and the valuable contribution of the Bondi Deposit.

這比2020年礦產資源估計值0.6Moz Au(標示)和1.9Moz Au(推斷)有了顯著增加 (2) (參見附錄B),並重點介紹了該項目的規模和邦迪礦牀的寶貴貢獻。

The combined oxide and transition component of the mineral resource now totals 0.2Moz gold (indicated) plus 0.8Moz gold (inferred) (4) , illustrating the ability to provide early plant feed to support a potential staged mine development.

現在,礦產資源的氧化物和過渡成分合計爲 0.2Moz 金幣 (已標示)加 0.8Moz 金幣 (推斷) (4) ,說明了提供早期植物飼料以支持潛在的分階段礦山開發的能力。

Re-interpretation and improved modelling of the Bondi Deposit has identified several higher-grade shoots within the mineral resource and will greatly assist in exploration targeting. This, combined with compelling regional targets at the Zanawa and Malbus Prospects are expected to deliver further increases to the mineral resource base.

對邦迪礦牀的重新解釋和改進建模已在礦產資源中發現了幾處更高品位的礦區,這將極大地幫助確定勘探目標。再加上扎納瓦和馬爾布斯勘探區令人信服的區域目標,預計將進一步擴大礦產資源基礎。

Sarama's President and CEO, Andrew Dinning commented:

薩拉瑪總裁兼首席執行官安德魯·丁寧評論說:

"We are very pleased with the significant increase to the mineral resource estimate for Sarama's 100%-owned Sanutura Project. This resource update marks the completion of a significant amount of technical work on historical exploration data and gives clear direction for future exploration where the Company is seeking to materially increase the Project's mineral resource.

“我們對薩拉瑪100%擁有的Sanutura項目的礦產資源估算值大幅增加感到非常滿意。此資源更新 標誌着有關歷史勘探數據的大量技術工作的完成,併爲公司尋求實質性增加該項目礦產資源的未來勘探提供了明確的方向。

The inclusion of the Bondi Deposit to the Project's mineral resource base provides a significant increase in high-grade, free-milling material and has the potential to materially improve start-up economics for the Project. In addition, the overall increase in the oxide and free-milling component to 0.2Moz Au (Indicated) plus 1.1Moz Au (Inferred) (6) has a material impact on the project development picture and our next key step will be to pursue the compelling exploration targets we have identified across the Project. These targets (8,9,10) , when combined with the current mineral resources, give us an exploration target in excess of 3-3.5 million ounces of gold.

將邦迪礦牀納入該項目的礦產資源基礎可顯著增加高品位自由銑削材料,並有可能實質性地提高該項目的啓動經濟性。此外,氧化物和自由銑削成分的總體增加爲 0.2Moz Au (已註明)加 1.1Moz Au (推斷) (6) 對項目開發前景產生了實質性影響,我們的下一個關鍵步驟將是實現我們在整個項目中確定的令人信服的勘探目標。這些目標 (8,9,10) ,再加上目前的礦產資源,爲我們設定了超過300萬至350萬盎司黃金的勘探目標。

The Project is being positioned as a long-life, multi-stage asset that can be built and paid for well before we have exploited the oxide resource and one which provides significant optionality and leverage to the gold price and remains key to the development of the southern Houndé Belt."

該項目被定位爲一種壽命長、多階段的資產,早在我們開採氧化物資源之前就可以建造和付款,它爲金價提供了重要的選擇性和槓桿作用,並且仍然是南部Houndé Belt發展的關鍵。”

Mineral Resource Estimate

礦產資源估算

The independent mineral resource estimate for Sarama's 100%-owned Sanutura Project was undertaken by Cube Consulting Pty Ltd (Perth, Western Australia) and features an extensive update to the interpretation and estimation of mineral resources at the Bondi Deposit, a key component of the Project. The update incorporates data from all exploration activities at the deposit, which have occurred over the period 2003 - 2018.

薩拉瑪100%擁有的Sanutura項目的獨立礦產資源估算由Cube Consulting Pty Ltd(西澳大利亞州珀斯)進行,其中包括對邦迪礦牀礦產資源的解釋和估算的廣泛更新,邦迪礦牀是該項目的關鍵組成部分。該更新包含了該礦牀所有勘探活動的數據,這些活動是在2003-2018年期間進行的。

The updated mineral resource for the Sanutura Project is:

薩努圖拉項目的最新礦產資源是:

  • 9.4Mt @ 1.9g/t Au for 0.6Moz gold (Indicated); plus
  • 52.7Mt @ 1.4g/t Au for 2.3Moz gold (Inferred) (1) .
  • 9.4Mt @ 1.9g/t Au 爲了 0.6Moz 黃金(已標示);加
  • 52.7Mt @ 1.4g/t Au 爲了 2.3Moz 黃金(推斷) (1)

This is comprised of mineral resources for the Tankoro Deposit of 9.4Mt @ 1.9g/t Au for 0.6Moz Au (Indicated) and 43.6Mt @ 1.4g/t Au for 1.9Moz (Inferred) and the Bondi Deposit of 9.2Mt @ 1.5g/t Au for 0.5Moz (Inferred)(refer Appendix A, Table A1).

這包括坦科羅礦牀的礦產資源 9.4Mt @ 1.9g/t Au 兌換 0.6Moz Au (已指示)和 43.6Mt @ 1.4g/t Au 售價 1.9Moz (推斷)和邦迪存款 9.2Mt @ 1.5g/t Au 兌換 0.5Moz (推斷)(請參閱附錄 A,表 A1)。

Table 1 summarises the updated mineral resource for the Project and Appendix A contains detailed breakdowns as well as notes outlining the methodology used for interpretation, estimation and classification.

表1概述了該項目的最新礦產資源,附錄A包含詳細的細目以及概述解釋、估算和分類所用方法的註釋。

The mineral resource features a higher-grade component of 6.3Mt @ 2.5g/t Au for 0.5Moz Au (Indicated) plus 29.8Mt @ 1.9g/t Au for 1.8Moz Au (Inferred) (3) which reflects the presence of numerous higher-grade zones within the mineralised systems. These zones are typically located in areas of structural complexity with an associated increase in the volume of the package of stacked lodes, which the Company would seek to leverage to provide early plant feed in a potential mine development. Figure 4 illustrates the core areas of the MM and MC Prospects at the Tankoro Deposit which feature higher-grade mineralisation in structurally complex settings.

礦產資源具有更高品位的成分 6.3Mt @ 2.5g/t Au 兌換 0.5Moz Au (已註明)加 29.8Mt @ 1.9g/t Au 兌換 1.8Moz Au (推斷) (3) 這反映了礦化系統中存在許多高品位區域。這些區域通常位於結構複雜的區域,隨之而來的是堆疊礦山體積的增加,該公司將尋求利用這些區域爲潛在的礦山開發提供早期植物飼料。圖 4 說明了 Tankoro 礦牀的 MM 和 MC 勘探區的核心區域,這些區域在結構複雜的環境中具有更高品位的礦化。

An increase in the oxide and transition components of the mineral resource to 3.2Mt @ 1.6g/t Au for 0.2Moz Au (Indicated) plus 23.4Mt @ 1.1g/t Au for 0.8Moz Au (Inferred) (4,5) has been delivered by the update and Sarama will specifically target this type of material in future drilling programs to provide early plant feed for a potential staged mine development.

礦產資源的氧化物和過渡成分增加到 3.2Mt @ 1.6g/t Au 兌換 0.2Moz Au (已註明)加 23.4Mt @ 1.1g/t Au 兌換 0.8Moz Au (推斷) (4,5) 已通過更新交付,Sarama將在未來的鑽探計劃中專門針對此類材料,爲潛在的分階段礦山開發提供早期植物飼料。

Significant quantities of modelled mineralisation remain unclassified and the subject of future drilling campaigns with the intent of converting into mineral resources.

大量的建模礦化仍未分類,這是未來鑽探活動的主題,目的是轉化爲礦產資源。

Table Notes

表格註釋

  1. Mineral resources are not mineral reserves and do not demonstrate economic viability.
  2. All tonnage, grade and ounces have been rounded and minor discrepancies in additive totals may occur.
  3. Weathering classification is based on visual assessment of drill core and cuttings by geologists and does not represent a definitive geo-metallurgical classification.
  4. Mineral resources are reported as a mining shape-constrained subset of the modelled mineral inventory following assessment for 'reasonable prospects for eventual economic extraction' by the generation of open pit optimisation shells (" OP ") and underground mining blockouts (" UG "). The assessment is not supported by a preliminary economic assessment or a feasibility study and the geological classification and reporting categorisations do not imply that mineral resources demonstrate economic viability. OP and UG constrained mineral resources are exclusive of each other.
  5. For the Tankoro Deposit, cut-off grades were determined using a gold price of US$1800/oz, metallurgical recoveries supported by testwork and based on oxide material being processed by a CIL flowsheet and transition and fresh material being processed by a flotation+BIOX®+CIL flowsheet and operating cost assumptions for mining, processing and G&A activities considered appropriate for the anticipated configuration of a potential development at the Project. Fresh material at the Guy, Legbenege and Poggle Prospects is assumed to be free-milling and reported at a cut-off grade of 0.3g/t Au. All other OP fresh mineral resources reported at a cut-off grade of 0.5g/t Au.
  6. For the Bondi Deposit, cut-off grades were determined using a gold price of US$1800/oz, metallurgical recoveries supported by testwork and based on material being processed by a CIL flowsheet and operating cost assumptions for mining, processing and G&A activities considered appropriate for the anticipated configuration of a potential development at the Project.
  1. 礦產資源不是礦產儲備,不顯示出經濟可行性。
  2. 所有噸位、等級和盎司均已四捨五入,添加劑總量可能存在細微差異。
  3. 風化分類基於地質學家對鑽芯和岩屑的目視評估,並不代表明確的地質冶金分類。
  4. 在通過生成露天礦優化殼對'最終經濟開採的合理前景'進行評估後,礦產資源被報告爲建模礦產庫存中受採礦形狀限制的子集(” OP “) 和地下采礦封鎖 (” UG “)。該評估沒有初步經濟評估或可行性研究的支持,地質分類和報告分類並不意味着礦產資源顯示出經濟可行性。OP 和 UG 受限的礦產資源是相互排斥的。
  5. 對於Tankoro礦牀,邊界品位是根據1800美元/盎司的黃金價格、由測試工作支持的冶金回收率、由CIL流程表和過渡流程處理的氧化物以及通過Flotation+Biox® +CIL流程表處理的新材料以及被認爲適合該項目潛在開發項目預期配置的採礦、加工和勘探活動的運營成本假設來確定的。假設Guy、Legbenege和Poggle Prospects的新材料是自由研磨的,報告的臨界品位爲0.3g/t Au。所有其他OP新鮮礦產資源報告的臨界品位爲0.5g/t Au。
  6. 對於邦迪礦牀,邊界品位是根據1800美元/盎司的黃金價格、由測試工作支持的冶金回收率、根據CIL流程表處理的材料以及被認爲適合該項目潛在開發項目預期配置的採礦、加工和勘探活動的運營成本假設來確定的。

Tankoro Deposit

Tankoro 存款

The mineral resource for the Tankoro Deposit (refer Figures 2 & 4) is principally contained in an extensive package of mineralised lenses, presenting as gold-quartz veinlets and disseminated gold-pyrite within quartz-feldspar-porphyry dykes and sediment-hosted quartz veins. The package is interpreted to extend over a semi-continuous strike length of approximately 16km in a trend that spans approximately 1.4km across the strike (refer Figure 2). A large portion of the mineral resource has only been drill-tested to approximately 70m depth, however drilling of certain higher-grade zones has shown the system to extend to 550m depth where it remains open. The mineralized corridor, as presently defined by drilling, lies within a 30km-long, gold-in-soil geochemical anomaly that remains a key focus for ongoing exploration.

坦科羅礦牀(參見圖 2 和 4)的礦產資源主要包含在大量礦化透鏡中,在石英長石斑岩和沉積物承載的石英礦脈中呈現爲金石英脈和浸染性金黃鐵礦。該包裹被解釋爲延伸到大約 16 千米的半連續走向長度,橫跨走向大約 1.4 千米(參見圖 2)。很大一部分礦產資源僅經過鑽探測試,深度約爲70米,但是對某些更高品位區域的鑽探表明,該系統可以延伸到550米深度,但仍處於開放狀態。按照目前鑽探的定義,礦化走廊位於一個長達30千米的土壤中含金的地球化學異常中,該異常仍然是正在進行的勘探的重點。

A second mineralised trend in the east of the Project area makes a minor contribution to the mineral resource estimate. This trend is also defined by a large gold-in-soil geochemical anomaly extending for 30km and features gold mineralisation hosted in quartz veins which have typically been drilled to a depth of 30-50m. The under-explored nature of the trend highlights the potential of the Project to host mineralisation of significance outside the historically well-drilled areas in the west and several zones within the trend will be targeted in upcoming exploration programs.

項目區東部的第二種礦化趨勢對礦產資源估算的貢獻微乎其微。這種趨勢還由延伸30公里的大型土壤中金地球化學異常所定義,其特點是金礦化存在於石英礦脈中,通常鑽探深度爲30-50米。這一趨勢尚未得到充分開發,這凸顯了該項目有可能在西部歷史上鑽探良好的地區之外承載重要的礦化區,在即將到來的勘探計劃中,該趨勢中的幾個區域將成爲目標區域。

Bondi Deposit

邦迪存款

The mineral resource for the Bondi Deposit (refer Figures 3 & 5) is contained in a series of mineralised lenses primarily hosted in a regionally extensive, sub-vertical shear zone system. The mineralisation typically presents as gold-quartz veins and veinlets within a range of lithological host units forming sub-vertical, semi-continuous lenses. These lenses strike N-S to NNE with several closely-spaced parallel lenses combining to form a mineralised package spanning up to 50m across the strike. The mineralised system extends for approximately 6km along strike and in its central area, features a proliferation of structurally-controlled minor lodes striking in a NNW to N-S direction. At its widest point in this area the mineralised package spans approximately 500m across.

邦迪礦牀的礦產資源(參見圖 3 和 5)包含在一系列礦化透鏡中,這些礦化透鏡主要存在於區域範圍廣泛的亞垂直剪切帶系統中。礦化通常表現爲金石英礦脈和礦脈,位於一系列巖性宿主單元內,形成亞垂直半連續透鏡。這些鏡片通過幾個間隔緊密的平行透鏡組合在一起,形成跨度可達 50 米的礦化層。礦化系統沿着走向延伸約6千米,在其中心區域,其特點是結構控制的小礦脈向西北向南偏北方向擴散。在該區域最寬處,礦化包橫跨大約 500 米。

Drilling at the deposit is extensive, with the central zone being largely informed by holes at 25m x 25-50m spacing in the near-surface, open-pittable areas. Drilling in a high-grade central zone has extended to a vertical depth of approximately 300m with the mineralisation remaining open. For a large part of the mineral resource, the drilling only extends to 150m below surface and in many areas only 50m below surface.

該礦牀的鑽探範圍很廣,中心區域主要受近地表露天礦區25m x 25-50m間距的孔洞的影響。在高品位中心區域的鑽探已擴展到大約300米的垂直深度,礦化區仍處於開放狀態。對於大部分礦產資源,鑽探僅延伸到地表以下150米,在許多地區,鑽探僅延伸到地表以下50米。

Exploration Targets

勘探目標

Gold mineralisation, within 5km of the Bondi Deposit occurs in a diverse range of geological settings and deposit types, has been intersected in recent drill programs. This includes disseminated gold associated with E-trending structural features, within and proximal to, intermediate intrusive units (eg. Zanawa Prospect; refer Sarama's news release of 20 September 2018), high-grade gold-quartz veins cutting fractured mafic volcanic rocks and gold-quartz veinlets associated with a regional shear zone.

在最近的鑽探計劃中,金礦化位於邦迪礦牀5公里以內,存在於不同的地質環境和礦牀類型中。這包括與E趨勢結構特徵相關的彌散性黃金,位於中間侵入單位內和附近(例如Zanawa Prospect;參見 Sarama 於 2018 年 9 月 20 日發佈的新聞稿)、切割斷裂的鎂鐵質火山岩的高品位金石英礦脈和與區域剪切帶相關的金石英礦脈。

More than 30 exploration targets have been identified by Sarama within the larger Sanutura Project area from soil geochemical surveys, IP geophysical surveys, airborne magnetic survey interpretation and historical drilling and these targets will be further explored with a view to establishing multiple satellite feed deposits.

薩拉瑪已經在更大的Sanutura項目區域內通過土壤地球化學調查、IP地球物理調查、機載磁測解釋和歷史鑽探確定了30多個勘探目標,並將進一步探索這些目標,以期建立多個衛星饋電礦牀。

In addition to the stated mineral resources, the Tankoro Deposit has a primary exploration target of a further 3.5-4.3Mt @ 1.2-1.4g/t Au for 135-190koz Au (8) , consisting of modelled and estimated mineralisation contained within the open pit shell and underground blockouts. A secondary exploration target of 12.0-14.7Mt @ 1.2-1.4g/t for 0.5-0.7Moz Au (9) has been modelled and estimated outside the constraining mining shapes. The Bondi Deposit has a primary exploration target of 2.5-3.1Mt @ 0.9-1.1g/t Au for 70-100koz Au (10) , consisting of modelled and estimated mineralisation contained within the open pit shell and underground blockouts.

除了上述礦產資源外,Tankoro礦牀的主要勘探目標是進一步勘探 3.5-4.3Mt @ 1.2-1.4g/t Au 兌換 135-190koz Au (8) ,包括露天礦殼體和地下封鎖區中經過建模和估計的礦化情況。次要勘探目標是 12.0-14.7Mt @ 1.2-1.4g/t 兌換 0.5-0.7Moz Au (9) 是在限制性採礦形態之外進行建模和估算的。邦迪礦牀的主要勘探目標是 2.5-3.1Mt @ 0.9-1.1g/t Au 換成 70-100koz Au (10) ,包括露天礦殼體和地下封鎖區中經過建模和估計的礦化情況。

While the potential quantity and grade of these exploration targets is conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource, they present viable exploration targets for the Company to pursue.

儘管這些勘探目標的潛在數量和品位本質上是概念性的,沒有足夠的勘探來定義礦產資源,也不確定進一步的勘探是否會導致目標被劃爲礦產資源,但它們爲公司提供了可行的勘探目標。

The project hosts the Tankoro and Bondi Deposits which have a combined mineral resource of 0.6Moz gold (indicated) and 2.3Moz gold (inferred) (1) .

薩拉瑪 100% 擁有 (12) Sanutura項目主要位於布基納法索西南部多產的Houndé Greenstone帶內,是該公司的勘探和開發重點。該項目擁有坦科羅和邦迪礦牀,它們的綜合礦產資源爲 0.6Moz 金幣(已標示)2.3Moz 金幣(推斷) (1)

Together, the deposits present a potential mine development opportunity featuring an initial, long-life CIL project which may be established and paid for by the significant oxide mineral resource base.

這些礦牀共同提供了潛在的礦山開發機會,其特點是最初的、壽命長的 CIL 項目,該項目可能由重要的氧化物礦產資源基礎建立和支付。

Sarama has built further optionality into its portfolio including a 600km² exploration position in the highly prospective Banfora Belt in south-western Burkina Faso. The Koumandara Project hosts several regional-scale structural features and trends of gold-in-soil anomalism extending for over 40km along strike.

Sarama在其投資組合中增加了更多可選性,包括在布基納法索西南部極具前景的邦福拉地帶進行600平方公里的勘探職位。Koumandara項目具有多個區域規模的結構特徵和沿走向延伸40多公里的土壤中金異常趨勢。

Sarama also holds an approximate 18% participating interest in the Karankasso Project Joint Venture (" JV ") which is situated adjacent to the Company's Sanutura Project in Burkina Faso and is a JV between Sarama and Endeavour Mining Corp (" Endeavour ") in which Endeavour is the operator of the JV. In February 2020, an updated mineral resource estimate of 709koz gold (11) was declared for the Karankasso Project JV.

薩拉馬還持有卡蘭卡索項目合資企業約18%的參與權益(” 合資企業 “) 它毗鄰該公司在布基納法索的Sanutura項目,是薩拉瑪和奮進礦業公司的合資企業(” 奮進 “)其中,奮進號是合資企業的運營商。2020年2月,更新了709koz黃金的礦產資源估計 (11) 已宣佈加入卡蘭卡索項目合資企業。

The Company's Board and management team have a proven track record in Africa and a strong history in the discovery and development of large-scale gold deposits. Sarama is well positioned to build on its current success with a sound strategy to surface and maximise the value of its property portfolio.

  11. Karankasso Project current mineral resource estimate - the current mineral resource estimate for the Karankasso Project of 12.74Mt @ 1.73g/t Au for 709koz Au (effective date of December 31, 2019) was disclosed on February 24, 2020 by Semafo Inc ("Semafo", since acquired by Endeavour Mining Corp. "Endeavour"). For further information regarding that mineral resource estimate, refer to the news release "Semafo: Bantou Project Inferred Resources Increase to 2.2Moz" dated February 24, 2020 and Semafo: Bantou Project NI43-101 Technical Report - Mineral Resource Estimate" dated April 3, 2020. The news release and technical report are available under Semafo's and Endeavour's profile on SEDAR at www.sedar.com . The mineral resource estimate was fully prepared by, or under the supervision of Semafo. Sarama has not independently verified Semafo's mineral resource estimate and takes no responsibility for its accuracy. Semafo, and now Endeavour, is the operator of the Karankasso Project JV and Sarama is relying on their Qualified Persons' assurance of the validity of the mineral resource estimate. Additional technical work has been undertaken on the Karankasso Project since the effective date but Sarama is not in a position to quantify the impact of this additional work on the mineral resource estimate referred to above.
  12. The Tankoro Exploration Permit, which hosts the Tankoro Deposit, is undergoing a process with the Government of Burkina Faso where it is required it be re-issued as a new full-term exploration permit and the Company continues to work with the relevant government departments to progress the re-issue of the exploration permit. The Company remains optimistic of a satisfactory outcome, however timeframe for the permit re-issue is indeterminate. Sarama has previously had a number of exploration permits re-issued, however there is no assurance of the timing and prospects for the re-issuance of the exploration permit. As a matter of practice, the application for re-issue is typically granted providing work done by the holder is significant and the application is submitted in a timely manner, with both conditions being satisfied by Sarama.

CAUTION REGARDING FORWARD LOOKING INFORMATION

謹慎使用前瞻性信息

Information in this news release that is not a statement of historical fact constitutes forward-looking information. Such forward-looking information includes, but is not limited to, the updated mineral resource estimate, statements regarding the Company's future exploration and development plans, the potential for the Sanutura and Karankasso Projects to host economic mineralisation, the potential for open pit and underground mining at the Sanutura Project, the potential to expand the present oxide component of the existing estimated mineral resources at the Sanutura Project, the reliability of the historical exploration work and estimates for artisanal mining depletion at the Bondi Deposit, the potential for the receipt of regulatory approvals and the timing and prospects for the re-issuance of the Tankoro Exploration Permit by the Government of Burkina Faso. Actual results, performance or achievements of the Company may vary from the results suggested by such forward-looking statements due to known and unknown risks, uncertainties and other factors. Such factors include, among others, that the business of exploration for gold and other precious minerals involves a high degree of risk and is highly speculative in nature; mineral resources are not mineral reserves, they do not have demonstrated economic viability, and there is no certainty that they can be upgraded to mineral reserves through continued exploration; few properties that are explored are ultimately developed into producing mines; geological factors; the actual results of current and future exploration; changes in project parameters as plans continue to be evaluated, as well as those factors disclosed in the Company's publicly filed documents.

本新聞稿中不陳述歷史事實的信息構成前瞻性信息。此類前瞻性信息包括但不限於最新的礦產資源估算、有關公司未來勘探和開發計劃的陳述、Sanutura和Karankasso項目承載經濟礦化的可能性、Sanutura項目露天和地下采礦的可能性、擴大薩努圖拉項目現有估計礦產資源中氧化物成分的可能性、歷史勘探工作的可靠性以及手工採礦的估計礦業枯竭邦迪礦牀、獲得監管部門批准的可能性以及布基納法索政府重新簽發坦科羅勘探許可證的時間和前景。由於已知和未知的風險、不確定性和其他因素,公司的實際業績、業績或成就可能與此類前瞻性陳述所暗示的結果有所不同。這些因素包括,除其他外,黃金和其他貴重礦物的勘探業務風險很高,本質上是高度投機性的;礦產資源不是礦產儲備,沒有表現出經濟可行性,也無法確定可以通過持續勘探將其升級爲礦產儲量;已勘探的財產很少最終被開發成生產礦山;地質因素;當前和未來勘探的實際結果;計劃中項目參數的變化繼續接受評估,以及公司公開提交的文件中披露的那些因素。

There can be no assurance that any mineralisation that is discovered will be proven to be economic, or that future required regulatory licensing or approvals will be obtained. However, the Company believes that the assumptions and expectations reflected in the forward-looking information are reasonable. Assumptions have been made regarding, among other things, the Company's ability to carry on its exploration activities, the sufficiency of funding, the timely receipt of required approvals, the price of gold and other precious metals, that the Company will not be affected by adverse political events, the ability of the Company to operate in a safe, efficient and effective manner and the ability of the Company to obtain further financing as and when required and on reasonable terms. Readers should not place undue reliance on forward-looking information.

無法保證發現的任何礦化都會被證明是經濟的,也無法保證將來會獲得所需的監管許可或批准。但是,公司認爲,前瞻性信息中反映的假設和預期是合理的。除其他外,已經做出了以下假設:公司開展勘探活動的能力、資金充足、及時獲得所需批准、黃金和其他貴金屬的價格、公司不會受到不利政治事件的影響、公司以安全、高效和有效的方式運營的能力,以及公司在需要時以合理條件獲得進一步融資的能力。讀者不應過分依賴前瞻性信息。

Sarama does not undertake to update any forward-looking information, except as required by applicable laws.

除非適用法律要求,否則Sarama不承諾更新任何前瞻性信息。

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

APPENDIX A - MINERAL RESOURCE ESTIMATION

附錄 A-礦產資源估算

Tankoro Deposit

Tankoro 存款

  1. The mineral resource estimate was undertaken by Cube Consulting Pty Ltd (" Cube "), a minerals industry consultancy based in Perth, Western Australia, which is independent of Sarama.
  2. The 12 prospect areas that are the subject of this mineral resource are located on the Tankoro and Ouangoro 2 exploration properties and the validated mineral resource drilling database contained the following drillhole physicals that were used directly in the modelling of the mineral inventory: 600 air-core (" AC ") drillholes (34,216m), 568 reverse-circulation (" RC ") drillholes (60,546m), 75 full length diamond drillholes (21,296m) and a further 103 diamond drillhole tails (15,411m) that were extensions to previously drilled RC holes.
  3. The mineral resource estimate used only diamond, RC and AC drilling data.
  4. The drilling was completed in several phases by Sarama and Acacia Mining plc between 7 th June 2011 and 6 th July 2019.
  5. Drilling was generally oriented on west-east lines, with a range of drill-line spacings used depending on geological complexity and the intent of the drill programs. Interpretations of mineralisation were made with drill fence spacing varying from approximately 25m to 600m, however areas of excessive drill spacing remain geologically 'unclassified' and do not contribute to the mineral resource. Within the lodes contributing to the mineral resource, drill spacing varies from 25-230m and is typically 50-100m.
  6. Collars for drillholes used in the mineral resource estimate have been surveyed using a differential GPS system which is considered to provide a location accuracy of <10cm horizontally and <15cm vertically.
  7. Downhole surveys have been conducted on all diamond and RC holes using either magnetic single-shot or gyro multi-shot electronic survey instruments. No downhole surveys were conducted on AC drillholes.
  8. Geological logging of drillholes includes state of weathering, lithology, alteration, mineralogy, structural defects and groundwater conditions. All drillhole logging data was compiled into a master drilling database.
  9. AC and RC drilling was logged and sampled over regular 1m intervals for the entire hole, whilst diamond holes were logged and sampled over varying intervals (average 0.9m sample length) according to geological observations. In the case of diamond drilling, samples submitted for assay were half-core. In the case of AC drilling, some sampled intervals were composited over 2m for initial assaying with the initial 1m constituents of the composites subsequently re-assays in areas proximal to mineralisation.
  10. Diamond drilling had length-weighted average core recoveries of 97%, with approximately 1.3% of mineralized samples (>0.1g/t Au) having core recoveries of less than 50%. Sample weight data is available for 26,538m of AC drilling (or 78% of total AC drill metres used directly in the mineral resource estimate) and had an average sample collection rate of 9kg/m. Sample weight data is available for 60,378m of RC drilling (or 99% of total RC drill metres used directly in the mineral resource estimate) and had an average sample collection rate of 23kg/m. Localised zones of poor AC and RC sample recovery and quality caused by wet drilling conditions were assessed on an individual basis to determine the suitability for inclusion in the mineral resource estimation as in many cases were excluded.
  11. AC and RC sample splitting was performed at Sarama's preparation facilities in Burkina Faso. In the case of wet AC and RC drilling, full samples were dried by wood-fire prior to splitting. Diamond core sawing was also undertaken at Sarama's preparation facility.
  12. Sampling and sample submission were conducted in accordance with a quality assurance/quality control program which includes the use of certified reference materials for diamond, RC and AC drilling and field duplicates for AC and RC drilling.
  13. All drilling samples are securely bagged at the preparation facility and assigned sample identification numbers prior to their transport to assay laboratories in Burkina Faso and Mali operated by SGS SA, Activation Laboratories Ltd, ALS Limited and Bigs Global to international standards.
  14. Gold content is determined by fire assay methods using a 50g charge, lead collection and an atomic absorption spectroscopy finish. Assay methods have a lower detection limit of at least 0.01 g/t Au.
  15. Structure, lithology, alteration, mineralisation, weathering and surface topography surfaces were interpreted in 3D by Cube using Seequent Leapfrog Geo TM and GEOVIA Surpac TM software.
  16. Lithological, structural and alteration information from drillhole logging was primarily used to develop interpretations of the mineralised domains and gold assays were used as a secondary determinant.
  17. Mineralised interpretations generally honour a 0.25 g/t Au lower cut-off. The interpretation was typically extended past the last drillhole intercept by 50m to 100m downdip and up to 200m along strike where the geological and grade continuity could be reasonably implied.
  18. Additional criteria of a minimum 2m downhole interval length, and the minimisation of internal dilution were considered during the interpretation of the mineralised domains. However, internal dilution was incorporated where required to preserve the overall continuity of the mineralised domains.
  19. The mineralisation interpretation consists of 205 individual domains, defined by lithological, weathering and spatial characteristics. Continuous mineralisation domains are visually robust and consistent across a range of cut-offs from zero to 1.0 g/t Au. In certain zones, higher-grade sub-domains were modelled to better reflect the occurrence of higher-grade mineralisation within a broader mineralized lode.
  20. The vertical extent of the reported mineral resources varies across the individual prospects with approximate vertical depths as follows: MM - 540m, MC - 470m, Phantom - 240m, Phantom East - 140m; Phantom West - 240m, Obi - 90m and Kenbobi - 80m, Djimbake, - 50m, Guy - 90m, Dlarakoro - 80m, Legbenege - 35m and Poggle - 20m.
  21. For the purposes of density measurement, a total of 4,389 samples were collected from drilling across the prospects hosting the mineral resource, covering all weathering types and representative lithologies. A density value was then assigned for each weathering types and representative lithologies in the mineral resource estimate.
  22. Downhole composites of 1m were extracted from the assay database based on the mineralised wireframes and form the basis for statistical analysis, variography and grade interpolation.
  23. Gold assays were reviewed on an individual domain basis to determine appropriate top-cuts for each domain to reduce the influence of grade outliers. The top-cuts that were applied to selected domains were all above the 95 th grade percentile. In general, the grade domains represent distinct geological and statistical populations and provide a robust basis for mineral resource estimation.
  24. Variography was completed to analyse the spatial continuity of the grade within the major mineralised domains using ISATIS® software. A total of 5 super-domains were selected for analysis to characterise the grade continuity for grade interpolation. The domains were selected based on them being well informed by drilling data, hosting the largest mineralised volumes and being representative of the main host lithology types and their spatial distribution across and along the mineralised trends. The resultant variogram models were used to determine the appropriate estimation parameters for grade interpolation into the block model for individual mineralised domains.
  25. GEOVIA Surpac TM software was used to perform the grade estimation into 2 block models (one for the western mineralised trend and one for the eastern mineralised trend within the Tankoro Deposit). Ordinary-kriging and inverse distance (ID 2 ) methodologies were used for the western and eastern trend estimates respectively. All block estimates were based on grade interpolation into parent cells with dimensions of 5m x 25m x 10m (XYZ) for each individual mineralised domain. In order to better approximate the mineralised domains, the block models were aligned on azimuths of N25° and N0° for the western and eastern mineralised trends respectively.
  26. Three gold grade interpolation passes were completed, where the first pass used the KNA derived parameters, a second pass with the search distance extended to approximately 200m and a final pass with the minimum samples reduced to two (2). All blocks unestimated after the third pass were assigned a value of 0.0001g/t Au and categorised as unclassified. Assigned block grades accounted for less than 0.1% of the total mineralised volume.
  27. Upon completion of the block model, swath plots were generated to compare the gold grades estimated for the blocks against composited raw gold grades on easting, northing and elevation on 10m, 50m and 20m spacings for all mineralised domains. The block model was further validated by conducting an 'inverse-distance-squared' estimate for comparison (total contained gold was within 2% for the two estimates, indicating no systematic bias in the mineral resource estimate).
  28. The block model was classified as 'indicated', 'inferred' and 'unclassified' according to geological and estimate confidence. Consideration was given to data density, geological and grade continuity, drill spacing, drill quality, material type, suitability of estimation methodology and local estimation bias.
  29. Modelled mineralisation was assessed for likelihood to have reasonable prospects of eventual economic extraction by generating open pit optimisation shells and underground mining blockouts. Open pit optimisations, based on the Lerchs-Grossmann algorithm, were conducted using GEOVIA Whittle TM software with assumed input parameters for gold price, metallurgical recovery, operating costs and pit wall angles. The US$1800/oz shell was selected to constrain the modelled mineralisation for reporting purposes. Modelled mineralisation in fresh material located beneath the extent of the open pit shell was assessed for potential suitability for underground mining using cut-off grade, strike and dip continuity, minimum mining width, minimum stope height, spatial distribution of blocks and pit/underground interaction criteria. 3D wireframes were generated on a lode-by-lode basis for modelled blocks meeting all criteria. Blocks captured within either the open pit or underground constraining mining shapes were flagged.
  30. Blocks flagged by the mining shape constraints were interrogated by a range of cut-off grades (by material type, by potential mining style) to report final mineral resources. The inputs for the calculation of the reporting cut-off grades reflected those inputs used for the generation of the constraining mining shapes. Mineralised material categorised geologically as 'unclassified' was excluded from the reporting of mineral resources.
  31. The resulting mineral resource estimate is compliant with the requirements of Canadian National Instrument 43-101, 2016 (" NI-43-101 ") and the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, 2012 (" The JORC Code ").
  32. The final block model included the estimated mineralised domains with attributes for prospect, weathering type, lithology, density, estimation domain code, geological classification, constraining flag for open pit and underground mining shapes and a flag for mineral resource.
  33. Tonnage-grade curves were generated for a range of reporting cut-off grades, material types and by prospect.

  9. 根據地質觀測,在固定的1米間隔內對整個鑽孔進行了記錄和採樣,而鑽石孔的記錄和採樣間隔不同(平均樣本長度爲0.9m)。就鑽石鑽探而言,提交化驗的樣本爲半核。就交流鑽探而言,一些採樣間隔在2m以上,用於初始分析,複合材料的初始1m成分隨後在礦化附近的區域進行重新檢測。
  10. 鑽石鑽探的長度加權平均岩心回收率爲97%,大約1.3%的礦化樣品(>0.1g/t Au)的岩心回收率低於50%。26,538m 的交流鑽探(佔礦產資源估算中直接使用的交流鑽孔總量的 78%)可獲得樣本重量數據,平均樣本採集率爲 9kg/m。樣本重量數據可用於60,378m RC 鑽探(佔直接用於礦產資源估算的總反滲透米的 99%),平均樣本採集率爲 23kg/m。空調和反滲透樣本回收率較差的局部區域並對溼式鑽探條件造成的質量進行了個人評估,以確定是否適合納入礦產資源估算被排除在外,因爲在許多情況下。
  11. AC 和 RC 樣本拆分是在布基納法索的薩拉瑪製備設施進行的。在溼式交流和反滲透鑽探中,全部樣品在分裂之前用柴火乾燥。薩拉馬的準備設施也進行了金剛石岩心鋸切。

  15. Cube 使用 Seequent Leapfrog Geo 以三維方式解釋了結構、巖性、蝕變、礦化、風化和地表地貌表面 TM 還有 GEOVIA Surp TM 軟件。
  16. 來自鑽孔測井的巖性、結構和蝕變信息主要用於對礦化域進行解釋,金分析被用作次要決定因素。
  17. 礦化解釋通常採用 0.25 g/t Au 的較低臨界值。解釋通常從最後一個鑽孔截距向下延伸50米至100米,沿走向延伸至200米,在可以合理地暗示地質和品位連續性的情況下。
  18. 在解釋礦化區域時,還考慮了至少2m的井下間隔長度和最大限度地減少內部稀釋等其他標準。但是,爲了保持礦化域的整體連續性,在必要時加入了內部稀釋法。
  19. 礦化解釋由205個單獨的區域組成,由巖性、風化和空間特徵定義。連續礦化域在從零到 1.0 g/t Au 的一系列截止值範圍內具有視覺穩定性和一致性。在某些區域,對更高品位的子域進行了建模,以更好地反映更寬的礦化礦脈中高品位礦化的發生情況。
  20. 報告的礦產資源的垂直範圍因個別勘探區而異,垂直深度大致如下:MM——540m,MC——470m,幻影——240m,幻影東——140m;Phantom West ——240m,Obi——90m 和Kenbobi——80m,Djimbake——50m,Guy——90m,Dlarakoro——80m,Legbenege——35m 和 Poggbenege Le-20 米。
  21. 出於密度測量的目的,在礦產資源所在地的鑽探區共收集了4,389份樣本,涵蓋了所有風化類型和代表性巖性。然後,在礦產資源估算中爲每種風化類型和代表性巖性分配了密度值。
  22. 根據礦化線框從分析數據庫中提取了1m的井下複合材料,構成了統計分析、變異分析和品位插值的基礎。
  23. 在單個域基礎上對黃金分析進行了審查,以確定每個域的適當頂切值,以減少等級異常值的影響。應用於選定域名的排行榜均高於 95 第四 成績百分位數。一般而言,品位域代表不同的地質和統計群體,爲礦產資源估算提供了堅實的基礎。
  24. 使用ISATIS® 軟件完成了變異分析,以分析主要礦化域內品位的空間連續性。共選擇了5個超域進行分析,以表徵等級插值的等級連續性。選擇這些域的基礎是它們充分了解了鑽探數據,擁有最大的礦化體積,代表了主要的宿主巖性類型及其在礦化趨勢上和沿線的空間分佈。生成的變異函數模型用於確定將品位插值到單個礦化區的區塊模型中的相應估計參數。
  25. GEOVIA Surp TM 軟件用於對兩個區塊模型進行品位估算(一個用於西部礦化趨勢,另一個用於坦科羅礦牀內的東部礦化趨勢)。普通克里金法和反向距離 (ID) 2 ) 方法分別用於西部和東部趨勢估計。所有區塊估算值均基於對母細胞的等級插值,每個礦化域的尺寸爲 5m x 25m x 10m (XYZ)。爲了更好地近似礦化域,區塊模型分別在西部和東部礦化趨勢的N25°和N0°的方位角上對齊。

  27. 區塊模型完成後,生成了條帶圖,將區塊的估計金品位與所有礦化區塊的東、北和海拔10m、50m和20m間距上的綜合原始金品位進行比較。通過進行 “反向距離平方” 估算進行比較,進一步驗證了區塊模型(兩個估計值的總含金量在2%以內,表明礦產資源估算中沒有系統偏差)。
  28. 根據地質和估算置信度,區塊模型被歸類爲 “指示性”、“推斷式” 和 “未分類”。考慮了數據密度、地質和品位連續性、鑽孔間隔、鑽孔質量、材料類型、估算方法的適用性以及局部估計偏差。
  29. 通過生成露天礦優化殼和地下采礦封鎖,對建模的礦化作用進行了評估,以確定最終實現合理的經濟開採前景的可能性。基於 Lerchs-Grossmann 算法的露天礦優化是使用 GEOVIA Whittle 進行的 TM 包含黃金價格、冶金回收率、運營成本和坑壁角度的假定輸入參數的軟件。選擇1800美元/盎司的外殼是爲了限制建模礦化,用於報告目的。使用截止品位、走向和傾角連續性、最小採礦寬度、最小採場高度、區塊的空間分佈和礦坑/地下相互作用標準,評估了位於露天礦殼下方的新鮮材料中的建模礦化是否可能適合地下采礦。三維線框是針對符合所有標準的建模區塊逐礦生成的。在露天礦坑或地下限制採礦形狀內捕獲的方塊均被標記。
  30. 按採礦形狀限制標記的區塊由一系列截止等級(按材料類型、按潛在採礦方式)進行詢問,以報告最終的礦產資源。用於計算報告截止等級的輸入反映了用於生成限制性採礦形狀的輸入。在地質學上被歸類爲 “未分類” 的礦化物質被排除在礦產資源報告之外。
  31. 由此得出的礦產資源估算符合 2016 年加拿大國家儀器 43-101 的要求(” NI-43-101 “) 以及 2012 年《澳大利亞勘探結果、礦產資源和礦石儲量報告守則》(” JORC 守則 “)。

1. The mineral resource estimate was undertaken by Cube Consulting Pty Ltd, a minerals industry consultancy based in Perth, Western Australia, which is independent of Sarama.

1。礦產資源估算是由Cube Consulting Pty Ltd進行的,該公司是一家位於西澳大利亞州珀斯的礦業諮詢公司,獨立於薩拉馬。

2. The 4 prospect areas that are the subject of this mineral resource are located on the Djarkadougou 2 exploration property and the validated mineral resource drilling database contained the following drillhole physicals that were used directly in the modelling of the mineral inventory: 14 air-core (" AC ") drillholes (531m), 689 reverse-circulation (" RC ") drillholes (49,021m) and 86 diamond drillholes (17,503m).

2。該礦產資源所涉及的4個勘探區域位於Djarkadougo 2號勘探區內,經過驗證的礦產資源鑽探數據庫包含以下直接用於礦產庫存建模的鑽孔實物圖:14 aircore (” AC “) 鑽孔 (531 米),689 個反向循環 (” RC “) 鑽孔(49,021 米)和 86 個鑽石鑽孔(17,503 米)。

3. The mineral resource estimate used only diamond, RC drilling data. Information from the AC holes were used to guide the interpretation of the mineralised lodes, but they were not incorporated in the estimation process.

3。礦產資源估算僅使用鑽石、反滲透鑽探數據。來自交流孔的信息被用來指導礦化礦脈的解釋,但這些信息並未納入估算過程。

4. The drilling was completed in several phases by Sarama (July 2017 - July 2018) and Orezone Gold Corporation (" Orezone ") (January 2003 - February 2016).

4。Sarama(2017 年 7 月至 2018 年 7 月)和 Orezone Gold Corporation(” Orezone “)(2003 年 1 月至 2016 年 2 月)。

5. Drilling on the property was undertaken along a range of conjugate orientations, predominantly 90°+270° and 110°+290°, and to a lesser extent 60°+240°, according to the observed and interpreted strike of mineralisation. A range of drill-line spacings were used depending on geological complexity and the intent of the drill programs. Interpretations of mineralisation were made with drill fence spacing varying from approximately 25m to 250m, however areas of excessive drill spacing remain geologically 'unclassified' and do not contribute to the mineral resource. Within the lodes contributing to the mineral resource, drill spacing varies from 25-100m and is typically 25m.

5。根據觀測和解釋的礦化走向,在該物業上鑽探的方向是一系列共軛方向,主要是90°+270°和110°+290°,在較小範圍內,鑽探的方向爲60°+240°。根據地質複雜性和鑽探計劃的意圖,使用了一系列的鑽探線間距。對礦化的解釋是,鑽孔圍欄間距從大約25米到250米不等,但是鑽探間距過大的區域在地質學上仍然 “未分類”,對礦產資源沒有貢獻。在爲礦產資源貢獻的礦脈內,鑽探間距從 25-100 米不等,通常爲 25m。

6. Collars for drillholes used in the mineral resource estimate have been surveyed using several different methods over various different exploration phases. In general, the collars were surveyed using either a differential GPS or total station systems. Minor check surveys on historical drill collars have been undertaken by Sarama using a differential GPS system which is considered to provide a location accuracy of <10cm horizontally and <15cm vertically, however additional surveying is required to improve confidence.

6。在不同的勘探階段,已經使用幾種不同的方法對礦產資源估算中使用的鑽孔項圈進行了調查。通常,使用差分 GPS 或全站儀系統對項圈進行測量。薩拉瑪使用差分 GPS 系統對歷史鑽項圈進行了小型檢查調查,該系統被認爲水平定位精度小於 10 厘米,垂直方向小於 15 厘米,但要提高可信度,還需要進行額外的測量。

7. Downhole surveys have been conducted on the majority of diamond and RC holes using either magnetic single-shot or gyro multi-shot electronic survey instruments. Some downhole surveys were conducted on AC drillholes.

7。已經使用磁性單發或陀螺儀多發電子勘測儀器對大多數金剛石和反滲透孔進行了井下調查。一些井下調查是在交流鑽孔上進行的。

8. Geological logging of drillholes includes state of weathering, lithology, alteration, mineralogy, structural defects and groundwater conditions. All drillhole logging data was compiled into a master drilling database.

8。鑽孔的地質記錄包括風化狀態、巖性、蝕變、礦物學、結構缺陷和地下水狀況。所有鑽孔記錄數據都已編譯到主鑽孔數據庫中。

9. AC and RC drilling was logged and sampled over regular 1m intervals for the entire hole, whilst diamond holes were logged and sampled over varying intervals (average 1.3m sample length) according to geological observations. In the case of diamond drilling, samples submitted for assay were half-core. In the case of regional AC drilling, some sampled intervals were composited over 2m for initial assaying. Some early (May 2003) RC drilling was sampled over regular 2m intervals.

9。根據地質觀測,在固定的1米間隔內對整個鑽孔進行了記錄和採樣,而鑽石孔的記錄和採樣間隔不同(平均樣本長度爲1.3m)。就鑽石鑽探而言,提交化驗的樣本爲半核。就區域交流鑽探而言,一些採樣間隔超過2m,用於初始化驗。一些早期(2003 年 5 月)的 RC 鑽探採樣間隔爲 2 米。

10. Diamond drilling within the database for the Djarkadougou 2 Property had core recovery data available for approximately 8,570m with a length-weighted average of 95%. Sample weight data is available for 7,530m of AC drilling within the database for the Djarkadougou 2 Property and had an average sample collection rate of 19kg/m. Sample weight data is available for 59,600m of RC drilling within the database for the Djarkadougou 2 Property and had an average sample collection rate of 27kg/m. Sample recovery and quality was not generally assessed, in part due to incomplete drilling and sampling records.

10。Djarkadougo 2礦產數據庫中的鑽石鑽探可獲得約8,570米的核心回收數據,長度加權平均值爲95%。Djarkadougo 2地塊的數據庫中提供了7530米交流鑽井的樣本重量數據,平均樣本採集率爲19kg/m。Djarkadougogu 2地塊數據庫中提供了59,600米反向鑽探的樣本重量數據,平均樣本收集率爲27kg/m。樣本回收率和質量沒有得到評估,部分原因是鑽探和採樣記錄不完整。

11. AC and RC sample splitting was performed at Sarama's and Orezone's preparation facilities in Burkina Faso. In the case of wet AC and RC drilling by Sarama, full samples were dried by wood-fire prior to splitting (Orezone's procedures are unknown). Diamond core sawing was also undertaken at Sarama's and Orezone's preparation facilities.

11。在布基納法索的Sarama和Orezone的製備設施中進行了AC和RC樣本拆分。就薩拉馬的溼式交流和反滲透鑽探而言,全部樣品在分裂之前用柴火乾燥(Orezone 的程序尚不清楚)。Sarama和Orezone的準備設施也進行了金剛石岩心鋸切。

12. Sampling and sample submission were conducted in accordance with a quality assurance/quality control program which includes the use of certified and uncertified reference materials for diamond, RC and AC drilling and field duplicates for AC and RC drilling. Ancillary field split, crush duplicate and lab pulp duplicate data was available for certain samples.

12。採樣和樣本提交是根據質量保證/質量控制計劃進行的,其中包括使用經過認證和未經認證的參考材料進行鑽石、反滲透和交流鑽探,使用現場副本進行交流和反滲透鑽探。某些樣本的輔助現場拆分、粉碎副本和實驗室紙漿重複數據可用。

13. All drilling samples are securely bagged at the preparation facility and assigned sample identification numbers prior to their transport to assay laboratories in Burkina Faso, Mali and Ghana operated by SGS SA, Transworld, Bigs Global, ALS Limited and Abilab.

13。所有鑽探樣本都安全地裝入製備設施並分配樣本識別號,然後運送到布基納法索、馬裏和加納由SGS SA、Transworld、Bigs Global、ALS Limited和Abilab運營的化驗實驗室。

14. Gold content was determined by a several methods (with lower detection limit of at least 0.01 g/t Au) including:

14。金含量是通過多種方法測定的(檢測下限至少爲 0.01 g/t Au),包括:

  • fire assay using a 50g charge of head material, lead collection and an atomic absorption spectroscopy finish; and
  • bulk leaching (" BLEG ") of head material, in 1kg or 2kg charges, in a NaCN solution using an atomic absorption spectroscopy finish. The leached tail of certain samples was subsequently analysed by fire assay (50g charge) to allow computation of a total gold content (solution + tail). In instances where the leach tail was not analysed by fire assay, the solution assay represents a partial determination of the gold content of the head material (given leach dissolutions have been observed to range from approximately 60-99%).
  • 使用 50 克的頭部材料、鉛收集和原子吸收光譜儀表面進行火試驗;以及
  • 批量浸出 (” BLEG “)在使用原子吸收光譜表面處理的NaCn溶液中以1kg或2kg的電荷爲單位的頭部材料。隨後通過火試驗(50g 裝藥)對某些樣品的浸出尾部進行了分析,以便計算出總金含量(溶液+尾巴)。在未通過火法分析浸出尾巴的情況下,溶液分析代表了對頭部材料金含量的部分測定(據觀察,浸出溶解度約爲60-99%)。

15. The prevalence of partial gold contents for samples in the database (originating from the Orezone era), prompted an extensive QAQC review by Sarama in Q1-Q3 2021. The review examined the performance of all assay lab + methodology combinations and reviewed assay repeatability and accuracy and extent of determination of total gold content for the head samples. In general, the review concluded that sample preparation by Orezone was likely to be of an acceptable standard, however the extensive use of uncertified reference materials (with likely poor manufacture and resultant erratic gold content) prohibits the definitive assessment of both sample preparation and lab analytical accuracy and repeatability. The review also concluded that the use of partial leaching of gold is less than ideal, particularly for samples within the interpreted mineralised lodes.

15。數據庫中樣本中部分金含量的普遍性(源自奧雷佐時代),促使薩拉瑪在 Q1-Q3 2021 年進行了廣泛的質量保證審查。該審查檢查了所有分析實驗室+方法組合的性能,並審查了分析的可重複性、準確性以及頭部樣本總金含量的測定範圍。總體而言,審查得出的結論是,Orezone的樣品製備可能達到可接受的標準,但是大量使用未經認證的參考材料(可能製造不佳,由此產生的金含量不穩定),無法對樣本製備和實驗室分析的準確性和可重複性進行明確評估。審查還得出結論,使用部分浸出金的方法並不理想,特別是對於解釋後的礦化礦脈內的樣品而言。

Given the assay dataset consists of full and partially determined gold content samples, it was decided to identify a 'pass subset' - comprised of full, or near full, gold content samples for use in a resource estimate. The following general process was adopted by Sarama to produce this subset:

鑑於測定數據集由完整和部分確定的含金量樣本組成,因此決定確定一個 “合格子集”,由完整或接近完整的金含量樣本組成,用於資源估算。薩拉瑪採用了以下一般流程來生成該子集:

  • flag samples with head fire assays as acceptable;
  • flag head BLEG assays with associated leach tail fire assays as acceptable;
  • flag samples with head BLEG assays only (that is, no associated leach tail fire assays) as acceptable if the leach dissolution of samples (on a batch-by-batch basis) were demonstrably high (<95%); and
  • to the extent possible, identify sample preparation and lab analytical accuracy and repeatability issues with any of the above samples and remove them from the 'pass subset'.
  • 將經過頭部射擊分析的樣本標記爲可接受;
  • flag head BLEG 檢測和相關的浸出尾火檢測結果爲可接受;
  • 如果樣品的浸出溶出度(逐批處理)明顯很高(
  • 儘可能找出上述任何樣本的樣本製備和實驗室分析精度和可重複性問題,並將其從 “通行證子集” 中刪除。

Sarama then selected 'pass subset' samples were then cross-referenced with those samples comprising the interpreted mineralised lodes (interpretation process outlined below). Composite intervals of samples intersecting the interpreted mineralised lodes that were not fully comprised of samples in the 'pass subset' were further assessed as to the materiality of the 'non-passing' samples. 'Non-pass' samples within the mineralised lode's composite interval were included in the 'pass subset' if one of the 3 conditions were satisfied:

然後,薩拉瑪選擇的 “通行子集” 樣本與包含解釋礦化礦脈的樣本進行交叉引用(解釋過程概述如下)。對 “未通過” 樣品的重要性進行了進一步評估,這些樣本與解釋的礦化礦脈相交的複合間隔,這些樣本不完全由 “通行子集” 中的樣品組成。如果滿足以下三個條件之一,則礦化礦脈複合區間內的 “未通過” 樣本包含在 “通行子集” 中:

  • the composite grade of the mineralised lode was ≤0.4g/t Au;
  • the contribution of 'non-pass' samples to the total gram x metre gold content for the composite interval of the mineralised lode was ≤15%; or
  • the composite interval of the mineralised lode was ≤3m.
  • 礦化礦脈的複合品位爲 ≤0.4g/t Au;
  • 在礦化礦脈複合區間,“未通過” 樣本佔總克 x 米金含量的比例爲 ≤ 15%;或
  • 礦化礦脈的複合間隔爲 ≤3m。

The resulting 'pass subset' was then used by Cube to perform geostatistical analysis and the estimation.

然後,Cube 使用生成的 “pass 子集” 進行地統計分析和估計。

16. Structure, lithology, alteration, mineralisation, weathering and surface topography surfaces were interpreted in 3D by Cube using Seequent Leapfrog Geo TM and GEOVIA Surpac TM software.

16。Cube 使用 Seequent Leapfrog Geo 以三維方式解釋了結構、巖性、蝕變、礦化、風化和地表地貌表面 TM 還有 GEOVIA Surp TM 軟件。

17. Mineralised lode interpretations generally honour a 0.30 g/t Au lower cut-off to define the mineralised interval within a drillhole. Lithological, structural and alteration information was also incorporated in the interpretation of the mineralised lodes. The interpretation was typically extended past the last drillhole intercept by <40m downdip and <30m along strike where the geological and grade continuity could be reasonably implied. 129 individual domains were interpreted.

17。礦化礦脈解釋通常遵守 0.30 g/t 金的下限值,以定義鑽孔內的礦化間隔。巖性、結構和蝕變信息也被納入礦化礦脈的解釋中。解釋通常延伸到最後一個鑽孔截距以外,向下傾小於40米,沿走向延伸小於30米,在那裏可以合理地暗示地質和品位連續性。對129個單獨的區域進行了解釋。

18. Additional criteria of a minimum 2m downhole interval length, and the minimisation of internal dilution were considered during the interpretation of the mineralised domains. However, internal dilution was incorporated where required to preserve the overall continuity of the mineralised domains.

18。在解釋礦化區域時,還考慮了至少2m的井下間隔長度和最大限度地減少內部稀釋等其他標準。但是,爲了保持礦化域的整體連續性,在必要時加入了內部稀釋法。

19. The vertical extent of the reported mineral resources varies across the individual prospects with approximate vertical depths as follows: Solo - 320m, Antilles - 125m, Malbus - 65m and Dengar - 55m.

19。報告的礦產資源的垂直範圍因勘探區而異,垂直深度大致如下:梭羅——320米,安的列斯群島——125米,馬爾布斯——65米,登加——55米。

20. Cube extracted 4,900 density measurements from the database provided by Sarama. Cube was not provided with information relating to the nature of the samples collected for density as well as methodology used to obtain the measurements and as such has taken the density data at face value. The samples were coded by weathering status and statistical analysis was carried out for each weathering domain. An average density value was assigned to each domain however a multimodal population was observed for the fresh sample population, suggesting that future geological modelling should be carried out to properly assign the density in the fresh zone.

20。Cube 從 Sarama 提供的數據庫中提取了 4,900 個密度測量值。Cube沒有獲得與密度採集的樣本性質有關的信息,也沒有提供用於獲得測量值的方法的信息,因此根據面值採集了密度數據。樣本按風化狀態編碼,並對每個風化域進行了統計分析。爲每個區域分配了平均密度值,但觀察到新樣本種群中存在多模式種群,這表明未來應進行地質建模,以正確分配新區域的密度。

21. The drillhole database was coded by the interpreted mineralised lodes and assessment of the raw assay interval lengths was carried out which determined a common sample length of 1m.

21。鑽孔數據庫由解釋的礦化礦脈編碼,並對原始分析間隔長度進行了評估,確定常見樣本長度爲1m。

22. The samples were composited to 1m downhole using the best fit method in Surpac, with a minimum threshold of 50%, meaning a minimum allowable composite size of 0.5m. A very small proportion (0.4%) of the samples did not satisfy these criteria, which are mainly associated with low Au grade value. Removal of these samples do not constitute a material risk to the estimate.

22。使用Surpac中的最佳擬合方法將樣品合成到井下1米,最低閾值爲50%,這意味着允許的最小複合尺寸爲0.5m。極小一部分(0.4%)的樣本不符合這些標準,這主要與金等級值低有關。移除這些樣本對估算不構成實質性風險。

23. The composited samples were subsequently coded by the QA-QC status extracted from Sarama's "Q1-Q3 2021 QA-QC assessment", where most importantly samples that were flagged as "FAIL" during this assessment were not incorporated in the estimation process.

23。隨後,根據Sarama的 “Q1-Q3 2021 QA-QC評估” 中提取的QA-QC狀態對合成樣本進行編碼,其中最重要的是,在此評估期間被標記爲 “不合格” 的樣本未納入估算過程。

24. Statistical analysis of the composited Au grade per mineralised lodes was conducted. Domains with high coefficient of variation (i.e. greater than 1.5), had grade caps applied. The capping thresholds were determined through analysis of the histogram, log probability plots of the domains of interest as well as the spatial location of the outliers. Local distance restrictions were also applied for selected domains where gold grade above a given threshold is not extrapolated past a chosen distance (around 30m), in order to mitigate the smearing of high grade into poorly informed areas.

24。對每個礦化礦脈的複合金品位進行了統計分析。變異係數高(即大於 1.5)的域採用了等級上限。上限閾值是通過分析直方圖、感興趣域的對數概率圖以及異常值的空間位置來確定的。當地距離限制也適用於不超過給定閾值的黃金等級推斷出選定距離(約30米)的選定域名,以減少高等級對信息不足地區的影響。

25. Variogram analysis was carried out using Supervisor software, on the major Domain 1001 as this domain best informed domain and is representative of the main mineralisation style. Gold assays within Domain 1001 consist of a combination of total gold assays and partial gold assays. The variogram analysis was carried out on the total gold assays only in order to avoid additional variability introduced from using a mixture of data. Normal score transformation was applied to the data prior to the analysis in order to mitigate the effect of outliers and to assist identification of the underlying structure of the gold variable. The resulting variogram models were back-transformed into real space for use in the estimation process.

25。變異圖分析是使用Supervisor軟件在主域1001上進行的,因爲該域信息最充分,代表了主要的礦化風格。Domain 1001 中的黃金分析包括總金測定和部分金測定的組合。對總金分析進行變異函數分析只是爲了避免使用混合數據會帶來額外的變異性。在分析之前,對數據應用了正態分數變換,以減輕異常值的影響並幫助識別金變量的潛在結構。生成的變異函數模型被反向轉換成真實空間,用於估算過程。

26. An omnidirectional variogram in the plane of mineralisation was defined for Domain 1001. This model was also used to determine the appropriate estimation parameters for grade interpolation into the block model. The variogram model for Domain 1001 was applied to the other domains, where the sill was adjusted to the variance of the domain of interest.

26。爲域 1001 定義了礦化平面中的全向變異函數。該模型還用於確定區塊模型等級插值所需的相應估計參數。將域 1001 的變異函數模型應用於其他域,其中根據感興趣域的方差對基準進行了調整。

27. GEOVIA Surpac TM software was used to perform the grade estimation into two separate block models (one for the western mineralised trend and one for the eastern mineralised trend within the Bondi Deposit). The ordinary-kriging (" OK ") methodology was used for both areas. All block estimates were based on grade interpolation into parent cells with dimensions of 12.5mE x 12.5mN x 5mRL and sub-blocked to 1.5625mE x 3.125mN x 1.25mRL for Bondi West. For Bondi East, the parent cell sizes are 20mE x 60mN x 20mRL and sub-blocked to 5mE x 3.75mN x 2.5mRL. The parent blocks sizes approximate half the average drillhole spacing in both areas.

27。吉奧維亞 Surpac TM 軟件用於對兩個獨立的區塊模型進行品位估算(一個用於西部礦化趨勢,另一個用於邦迪礦牀內的東部礦化趨勢)。普通克里金法 (” “) 這兩個領域都使用了方法。所有區塊估計值均基於對母細胞的等級插值,其維度爲12.5mE x 12.5mN x 5mRL,邦迪西部的子屏蔽爲1.5625Me x 3.125mn x 1.25Mrl。對於 Bondi East,母細胞大小爲 20mE x 60mN x 20mRL,子封鎖爲 5mE x 3.75mN x 2.5MRL。父塊的大小大約是這兩個區域平均鑽孔間距的一半。

28. Gold grades were estimated in the block model using a single pass approach with a 300m search ellipse, a minimum number of samples of 6 and maximum number of samples of 16. For poorly informed domains, the minimum number of samples was relaxed to the number of samples inside the domain if less than 6. Most of the blocks in the interpreted mineralised lodes were estimated using a single pass. Only two domains out of 129 domains had un-estimated blocks after the first pass and these blocks were assigned the estimated mean gold grade for the corresponding domain.

28。區塊模型中的黃金等級是使用單程法估算的,搜索橢圓爲300m,樣本的最小數量爲6,最大樣本數爲16。對於知情不足的領域,如果小於 6 個,則最低樣本數量放寬爲該域內的樣本數量。解釋後的礦化礦脈中的大多數區塊都是使用單次通道估算的。在129個域名中,只有兩個域名在第一次通過後有未估算的區塊,這些區塊被分配了相應域的估計平均黃金等級。

29. Validation of the estimate was carried out by visually comparing the block estimate with the drillhole data. Statistical comparison of the gold grades between the declustered capped composites and the OK estimate were computed on domain-by-domain basis. The differences are within acceptable ranges of the classification of the resource. Swath plots in the Northing, Easting and RL directions were also generated using varying slicing width (25-50m) and there is no observed significant bias between the capped composite / declustered capped composite and the gold grade estimate at a local scale. A check estimate using Inverse Distance Squared (" ID 2") methodology was also carried out and overall, there is a difference of less than 2% between the two estimation methodologies, which is considered to be immaterial to the estimate.

29。通過對區塊估計值與鑽孔數據進行直觀比較來驗證估算值。去簇封頂複合材料與OK估計值之間的金品位的統計比較是逐領域計算的。差異在資源分類的可接受範圍內。北向、東向和向右方向的條帶圖也是使用不同的切片寬度(25-50m)生成的,在局部尺度的上限複合/去簇封頂複合材料和金品位估計值之間沒有觀察到明顯的偏差。使用反距離平方 (”) 進行檢查估算值 身份證 2“) 還採用了方法,總體而言,兩種估算方法之間的差異不到2%,這被認爲對估算無關緊要。

30. The block model was classified as 'inferred' and 'unclassified' according to geological and estimate confidence. Consideration was given to data density, geological and grade continuity, drill spacing, drill quality, material type, assay reliability assessment, suitability of estimation methodology and local estimation bias.

30。根據地質和估算置信度,區塊模型被歸類爲 “推斷” 和 “未分類”。考慮了數據密度、地質和品位連續性、鑽孔間隔、鑽孔質量、材料類型、分析可靠性評估、估算方法的適用性以及局部估計偏差。

31. Artisanal mining is noted to have occurred at the Solo, Cassian and Zanawa Prospects. Depletion of mineralisation by this artisanal mining was reflected in the block model by coding affected blocks with open pit and underground depletion factors.

31。據指出,梭羅、卡西安和扎納瓦勘探區均有手工採礦。通過使用露天和地下枯竭係數對受影響的區塊進行編碼,這種手工採礦對礦化的消耗反映在區塊模型中。

  1. In the case of open pit depletion, a pit crest offset perimeter was surveyed in affected areas and visual estimates of pit depths were recorded at approximately 15m intervals along strike. A 3D void model was constructed (assuming vertical walls) and visually compared to the interpreted mineralisation. As the mineralised lodes are generally sub-vertical and planar and the artisanal mining generally extracted the full width of the lodes, a 2D polygonal zone of the affected area was approximated using bounding northings and RLs. Interpreted mineralised blocks (for affected lodes) within the affected zone were assigned open pit depletion factors of 100%. Pit depths were generally in the range of 20-30m.
  2. In the case of underground depletion, discussions with artisanal miners were used estimate the depth extent of underground workings developed from the floors of the pits. As the mineralised lodes are generally sub-vertical and planar, a 2D polygonal zone of the affected area was approximated using bounding northings and RLs. Underground workings were noted to be 1-2m in width, which was compared to an average width of interpreted mineralisation in the affected zone to compute an average extraction factor. It was assumed that one underground gallery was present in the workings, however two galleries were assumed to be present in wider areas (>10m). Computed mining factors ranged 20-40%. Assumed extraction factors of 50% were then applied to reflect the likely presence of stability pillars and remnant areas. Resultant overall underground depletion factors ranging 10-20% were applied to all interpreted mineralised blocks in the affected zone (for the affected lodes).
  1. 就露天礦枯竭而言,對受影響地區的礦坑頂偏移周長進行了測量,並記錄了走向沿線每隔約15米的間隔對礦坑深度的直觀估計。構建了一個三維空隙模型(假設牆壁是垂直的),並在視覺上與解釋的礦化進行了比較。由於礦化礦脈通常是亞垂直和平面的,而手工採礦通常會提取礦脈的整個寬度,因此使用邊界北方和 RL 對受影響區域的二維多邊形區域進行了近似估算。受影響區域內解釋的礦化區塊(針對受影響礦脈)的露天礦損耗係數爲100%。礦坑深度通常在20-30米之間。
  2. 就地下枯竭而言,通過與手工採礦者的討論,估算了從礦坑地板開採的地下作業的深度。由於礦化礦脈通常是亞垂直和平面的,因此使用邊界北方和 RL 對受影響區域的二維多邊形區域進行了近似估算。注意到地下作業的寬度爲1-2米,將其與受影響區域解釋礦化的平均寬度進行比較,以計算出平均開採係數。假設施工中有一個地下畫廊,但是假設兩個畫廊位於更廣闊的區域(>10m)。計算出的採礦係數介於 20-40% 之間。然後使用假設的提取係數爲50%,以反映穩定柱和殘餘區域的可能存在。由此得出的總體地下消耗係數在10-20%之間,適用於受影響區域內所有已解釋的礦化區塊(針對受影響的礦脈)。

The depletion factors were used to inform the determination of the mineralised areas to have reasonable prospects of eventual economic extraction (" RPoEEE ").

消耗係數被用來爲確定礦化區域是否具有合理的最終經濟開採前景提供依據(” rpoeee “)。

32. Modelled mineralisation was assessed for likelihood to have RPoEEE by generating open pit optimisation shells and underground mining blockouts. Open pit optimisations, based on the Lerchs-Grossmann algorithm, were conducted using GEOVIA Whittle TM software with assumed input parameters for gold price, metallurgical recovery, operating costs and pit wall angles. The US$1800/oz shell was selected to constrain the modelled mineralisation for reporting purposes. Modelled mineralisation in fresh material located beneath the extent of the open pit shell was assessed for potential suitability for underground mining using cut-off grade, strike and dip continuity, minimum mining width, minimum stope height, spatial distribution of blocks and pit/underground interaction criteria. 3D wireframes were generated on a lode-by-lode basis for modelled blocks meeting all criteria. Blocks captured within either the open pit or underground constraining mining shapes were flagged.

32。通過生成露天礦優化殼和地下采礦封鎖,對建模的礦化情況進行了評估,以確定出現 rPoEEE 的可能性。基於 Lerchs-Grossmann 算法的露天礦優化是使用 GEOVIA Whittle 進行的 TM 包含黃金價格、冶金回收率、運營成本和坑壁角度的假定輸入參數的軟件。選擇1800美元/盎司的外殼是爲了限制建模礦化,用於報告目的。使用截止品位、走向和傾角連續性、最小採礦寬度、最小採場高度、區塊的空間分佈和礦坑/地下相互作用標準,評估了位於露天礦殼下方的新鮮材料中的建模礦化是否可能適合地下采礦。三維線框是針對符合所有標準的建模區塊逐礦生成的。在露天礦坑或地下限制採礦形狀內捕獲的方塊均被標記。

33. Blocks flagged by the mining shape constraints were interrogated by a range of cut-off grades (by material type, by potential mining style) to report final mineral resources. The inputs for the calculation of the reporting cut-off grades reflected those inputs used for the generation of the constraining mining shapes. Mineralised material categorised geologically as 'unclassified' was excluded from the reporting of mineral resources.

33。按採礦形狀限制標記的區塊由一系列截止等級(按材料類型、按潛在採礦方式)進行詢問,以報告最終的礦產資源。用於計算報告截止等級的輸入反映了用於生成限制性採礦形狀的輸入。在地質學上被歸類爲 “未分類” 的礦化物質被排除在礦產資源報告之外。

34. The resulting mineral resource estimate is compliant with the requirements of Canadian National Instrument 43-101, 2016 (" NI-43-101 ") and the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, 2012 (" The JORC Code ").

34。由此得出的礦產資源估算符合 2016 年加拿大國家儀器 43-101 的要求(” NI-43-101 “) 以及 2012 年《澳大利亞勘探結果、礦產資源和礦石儲量報告守則》(” JORC 守則 “)。

35. The final block model included the estimated mineralised domains with attributes for prospect, weathering type, density, estimation domain code, geological classification, constraining flag for open pit and underground mining shapes and a flag for mineral resource.

35。最終的區塊模型包括估計的礦化域,其屬性包括前景、風化類型、密度、估算域代碼、地質分類、露天和地下采礦形狀的限制標誌以及礦產資源標誌。

Tonnage-grade curves were generated for a range of reporting cut-off grades, material types and by prospect.

噸位曲線是針對一系列報告的截止品位、材料類型和潛在客戶生成的。

Table Notes

表格註釋

  1. Mineral resources are not mineral reserves and do not demonstrate economic viability.
  2. All tonnage, grade and ounces have been rounded and minor discrepancies in additive totals may occur.
  3. Mineral resources are reported as a mining shape-constrained subset of the modelled mineral inventory following assessment for 'reasonable prospects for eventual economic extraction' by the generation of open pit optimisation shells (" OP ") and underground mining blockouts (" UG "). The assessment and is not supported by a preliminary economic assessment or a feasibility study and the geological classification and reporting categorisations do not imply that mineral resources demonstrate economic viability.
  4. In the case of the Tankoro Deposit, cut-off grades were determined using a gold price of US$1800/oz, metallurgical recoveries supported by testwork and based on oxide material being processed by a CIL flowsheet and transition and fresh material being processed by a flotation+BIOX®+CIL flowsheet and operating cost assumptions for mining, processing and G&A activities considered appropriate for the anticipated configuration of a potential development at the Project.
    • OP Oxide and transition material reported at a cut-off grade of 0.2g/t Au and 0.3g/t Au respectively.
    • OP Fresh material at the Guy, Legbenege and Poggle Prospects is assumed to be free-milling and reported at a cut-off grade of 0.3g/t Au. All other OP fresh mineral resources reported at a cut-off grade of 0.5g/t Au.
    • UG fresh material mineral resources reported at a cut-off grade of 1.6g/t Au.
  5. In the case of the Bondi Deposit, cut-off grades were determined using a gold price of US$1800/oz, metallurgical recoveries supported by testwork and based on oxide, transition and fresh material being processed by a CIL flowsheet and operating cost assumptions for mining, processing and G&A activities considered appropriate for the anticipated configuration of a potential development at the Project.
    • OP material is reported at a cut-off grade of 0.2g/t Au (oxide) and 0.3g/t Au (transition & fresh).
    • UG fresh material mineral resources reported at a cut-off grade of 1.5g/t Au.

  4. 就坦科羅礦牀而言,邊界品位是根據1800美元/盎司的黃金價格、由測試工作支持的冶金回收率、由CIL流程和過渡流程處理的氧化物以及通過Flotation+Biox® +CIL流程表處理的新材料以及被認爲適合該項目潛在開發項目預期配置的採礦、加工和勘探活動的運營成本假設來確定的。
    • OP 氧化物和過渡材料的臨界品位分別爲 0.2g/t Au 和 0.3g/t Au。
    • OP Guy、Legbenege和Poggle Prosperts的新鮮材料被假定爲自由研磨,報告的臨界品位爲0.3g/t Au。所有其他OP新鮮礦產資源報告的臨界品位爲0.5g/t Au。

Table Notes

表格註釋

  1. Mineral resources are not mineral reserves and do not demonstrate economic viability.
  2. All tonnage, grade and ounces have been rounded and minor discrepancies in additive totals may occur.
  3. Mineral resources are reported as a mining shape-constrained subset of the modelled mineral inventory following assessment for 'reasonable prospects for eventual economic extraction' by the generation of open pit optimisation shells (" OP ") and underground mining blockouts (" UG "). The assessment and is not supported by a preliminary economic assessment or a feasibility study and the geological classification and reporting categorisations do not imply that mineral resources demonstrate economic viability. OP and UG constrained mineral resources are exclusive of eachother.
  4. Constraining mining shapes were generated using a gold price of US$1800/oz, metallurgical recoveries supported by testwork and based on oxide material being processed by a CIL flowsheet and transition and fresh material being processed by a flotation+BIOX®+CIL flowsheet and operating cost assumptions for mining, processing and G&A activities considered appropriate for the anticipated configuration of a potential development at the deposit.
  1. 礦產資源不是礦產儲備,不顯示出經濟可行性。
  2. 所有噸位、等級和盎司均已四捨五入,添加劑總量可能存在細微差異。
  3. 在通過生成露天礦優化殼對'最終經濟開採的合理前景'進行評估後,礦產資源被報告爲建模礦產庫存中受採礦形狀限制的子集(” OP “) 和地下采礦封鎖 (” UG “)。該評估沒有初步經濟評估或可行性研究的支持,也沒有地質分類和報告分類的支持,並不意味着礦產資源顯示出經濟可行性。OP 和 UG 受限的礦產資源是相互排斥的。
  4. 限制性採礦形態是使用1800美元/盎司的黃金價格、由測試工作支持的冶金回收率,並基於CIL流程和過渡流程處理的氧化物材料,以及通過浮選+Biox® +CIL流程表處理的新材料,以及被認爲適合礦牀潛在開發項目預期配置的採礦、加工和勘探活動的運營成本假設。

Table Notes

表格註釋

  1. Mineral resources are not mineral reserves and do not demonstrate economic viability.
  2. All tonnage, grade and ounces have been rounded and minor discrepancies in additive totals may occur.
  3. Weathering classification is based on visual assessment of drill core and cuttings by geologists and does not represent a definitive geo-metallurgical classification.
  4. Mineral resources are reported as a mining shape-constrained subset of the modelled mineral inventory following assessment for 'reasonable prospects for eventual economic extraction' by the generation of open pit optimisation shells (" OP ") and underground mining blockouts (" UG "). The assessment is not supported by a preliminary economic assessment or a feasibility study and the geological classification and reporting categorisations do not imply that mineral resources demonstrate economic viability. OP and UG constrained mineral resources are exclusive of each other.
  5. Cut-off grades were determined using a gold price of US$1800/oz, metallurgical recoveries supported by testwork and based on oxide material being processed by a CIL flowsheet and transition and fresh material being processed by a flotation+BIOX®+CIL flowsheet and operating cost assumptions for mining, processing and G&A activities considered appropriate for the anticipated configuration of a potential development at the Project.
  6. Fresh material at the Guy, Legbenege and Poggle Prospects is assumed to be free-milling and reported at a cut-off grade of 0.3g/t Au. All other OP fresh mineral resources reported at a cut-off grade of 0.5g/t Au. UG fresh material mineral resources reported above a cut-off grade of 1.6g/t Au.
  1. 礦產資源不是礦產儲備,不顯示出經濟可行性。
  2. 所有噸位、等級和盎司均已四捨五入,添加劑總量可能存在細微差異。
  3. 風化分類基於地質學家對鑽芯和岩屑的目視評估,並不代表明確的地質冶金分類。
  4. 在通過生成露天礦優化殼對'最終經濟開採的合理前景'進行評估後,礦產資源被報告爲建模礦產庫存中受採礦形狀限制的子集(” OP “) 和地下采礦封鎖 (” UG “)。該評估沒有初步經濟評估或可行性研究的支持,地質分類和報告分類並不意味着礦產資源顯示出經濟可行性。OP 和 UG 受限的礦產資源是相互排斥的。
  5. 臨界品位是根據1800美元/盎司的黃金價格、由測試工作支持的冶金回收率、由CIL流程和過渡流程處理的氧化物以及通過浮選+Biox® +CIL流程表處理的新材料以及被認爲適合該項目潛在開發項目預期配置的採礦、加工和併購活動的運營成本假設來確定的。
  6. 假設Guy、Legbenege和Poggle Prosperts的新材料是自由研磨的,報告的臨界品位爲0.3g/t Au。所有其他OP新鮮礦產資源報告的臨界品位爲0.5g/t Au。據報道,UG新鮮材料礦產資源的臨界品位高於1.6克/噸金的臨界品位。
