- Contained metal content in the indicated open pit category includes 317 million pounds of copper, 263 million pounds of nickel and 452,000 ounces of combined palladium, platinum and gold.
- Both deposits remain partly open along strike and at depth, and the Company holds the mineral rights to three other near-surface mineral deposits in the belt that could augment the mineral resource inventory in the future.
- Both deposits have had extensive metallurgical test work completed over multiple campaigns with results indicating that saleable sulfide concentrates can be produced (nickel at Makwa; separate copper and nickel concentrates at Mayville).
- The main factors contributing to the increased resources from previous estimates are improvements in modelled metallurgical recoveries, changes in metal prices and forex used in the resource calculation and additional drilling.
- The Mayville Deposit has no royalty; the Makwa Deposit has a 1% NSR royalty of which one half of a percent can be re-purchased for CAD$500,000.
- There are no offtake obligations on either of the deposits. The Company is currently seeking expressions of interest to fund resource expansion and project development through marketing of nickel and copper offtake rights for the project.
- The target/model for the project is +80 million tonnes of open pit resources augmented by the delineation of high-grade massive sulfide deposits throughout the belt.
- The Company has the mineral rights to the majority of the prospective Bird River Greenstone belt which has a geologic analogue to the McFaulds Lake Greenstone Belt which hosts the Ring of Fire deposits (see reference 2 at end of the press release)
- Among the economic parameters used in the mineral resource estimate, metal prices for the key metals are US$3.75 lb for copper and $9 lb for nickel.
- Strip ratios for the resource shells were 3.2 for Mayville and 4.7 for Makwa and are provided in the resource Tables 1A and 1B.
- Company plans to commence an initial phase of exploration drilling later in 2024 to test high priority nearby targets including possible massive sulphide targets identified from the recent geophysical review.
- 所述露天礦類別中所含的金屬含量包括3.17億磅銅、2.63億磅鎳和45.2萬盎司的合金、鉑金和金。
- 這兩個礦牀在走向和深度均處於部分開放狀態,該公司持有該地帶其他三個近地表礦牀的礦產權,這可能會增加未來的礦產資源庫存。
- 這兩個礦牀已經通過多次活動完成了大量的冶金測試工作,結果表明可以生產出可銷售的硫化物精礦(在Makwa生產鎳;在梅維爾分開銅和鎳精礦)。
- 與先前的估計相比,導致資源增加的主要因素是模擬冶金回收率的改善、資源計算中使用的金屬價格和外匯的變化以及額外的鑽探。
- 梅維爾存款沒有特許權使用費;Makwa存款有1%的NSR特許權使用費,其中一半的百分比可以花50萬加元回購。
- 這兩筆存款都沒有承購義務。該公司目前正在尋求意向書,通過營銷該項目的鎳和銅承購權來爲資源擴張和項目開發提供資金。
- 該項目的目標/模型是8000萬噸露天資源,再加上整個地帶上高品位塊狀硫化物礦牀的劃定。
- 該公司擁有大部分潛在的伯德河格林斯通帶的礦產權,該帶的地質類似於存放火環礦牀的麥克福茲湖綠石帶(參見新聞稿末尾的參考文獻 2)
- 在礦產資源估算中使用的經濟參數中,主要金屬的金屬價格爲銅3.75美元和鎳的9磅價格。
- 資源殼的剝離比率爲梅維爾的3.2,Makwa的資源殼帶寬率爲4.7,見資源表1A和1B。
- 該公司計劃在2024年晚些時候開始勘探鑽探的初始階段,以測試附近的高優先目標,包括最近的地球物理審查中確定的可能的大規模硫化物目標。
Robin Dunbar, CEO of Grid Metals, commented, "The resource estimate announced today provides impetus for further exploration and continued expansion of the MM copper/nickel Project. The MM Project resource is a conventional and near surface copper-nickel sulfide resource with readily apparent upside. The Project is ideally located to service critical metals demand in North America. The Mayville deposit is located directly adjacent to the Company's advanced exploration stage Donner Lithium Project which is currently progressing through the mine permitting process. We see tremendous synergies between our copper/nickel and lithium project development plans as we continue to build the mineral resources necessary to develop an important critical metals production and processing hub in a Tier 1 mining jurisdiction."
Grid Metals首席執行官羅賓·鄧巴評論說:“今天公佈的資源估算爲進一步勘探和持續擴張MM銅/鎳項目提供了動力。MM Project資源是一種傳統的近地表銅鎳硫化物資源,具有明顯的上升空間。該項目地理位置優越,可滿足北美的關鍵金屬需求。梅維爾礦牀直接位於該公司高級勘探階段的唐納鋰項目附近,該項目目前正在進行礦山許可程序。隨着我們繼續建設在一級採礦管轄區開發重要的關鍵金屬生產和加工中心所需的礦產資源,我們看到銅/鎳和鋰項目開發計劃之間存在巨大的協同效應。”
Project Overview
項目概述
The MM Project includes a copper-rich (Mayville) and a nickel-rich (Makwa) disseminated magmatic sulfide deposit along with three additional near-surface deposits (Page, Ore Fault, and New Manitoba) which were acquired by Grid in April 2023. The Mayville and Makwa deposits are located in the northern and southern parts of the Bird River Greenstone Belt, respectively, in southeastern Manitoba (see Figure 1). The Bird River Greenstone Belt and its mineral occurrences have been the subject of multiple research projects including research work completed under the Targeted Geoscience Initiative by the Canadian Geological Survey. The Project area has been identified as being a direct analogue to the Ring of Fire belt in northwestern Ontario (Houlé et al., 2020) which hosts several significant mineral deposits.
MM項目包括一個富銅(梅維爾)和一個富含鎳(Makwa)的浸染岩漿硫化物礦牀,以及另外三個近地表礦牀(佩奇、礦石斷層和新曼尼託巴),這些礦牀於2023年4月被電網收購。梅維爾和馬克瓦礦牀分別位於曼尼托巴省東南部伯德河綠巖帶的北部和南部(見圖1)。伯德河綠巖帶及其礦物礦牀一直是多個研究項目的主題,其中包括加拿大地質調查局在 “有針對性的地球科學計劃” 下完成的研究工作。該項目區域已被確定爲與安大略省西北部的環火帶(Houleé等人,2020年)的直接類似區域,該地帶擁有多個重要的礦牀。
The Project consists of a mining lease and mineral claims held by the Company and its subsidiaries. It is readily accessible year-round, by provincial highways from the capital city of Winnipeg located ~145 km to the southwest. The Mayville deposit is situated two km north of the Company's Donner Lithium Project where the Company has published a NI 43-101 Resource Estimate Technical Report. Both the Donner and MM Projects will benefit from efficiencies in exploration, government and First Nations relations, permitting and infrastructure.
該項目包括公司及其子公司持有的採礦租約和礦產索賠。從位於西南約145公里的首都溫尼伯出發,可通過省級公路全年輕鬆抵達。梅維爾礦牀位於該公司唐納鋰項目以北兩公里處,該公司已在該項目發佈了NI 43-101資源估算技術報告。Donner和MM項目都將受益於勘探、政府與原住民關係、許可和基礎設施方面的效率。
In total, 99 mineral claims and one mineral lease (Makwa) are held for base metal exploration by the Company and its subsidiaries. A further 51 mining claims are under option from Gossan Resources with a $300,000 option payment remaining under the option and due in April 2025. The Makwa Deposit is held under a Mineral Lease granted by the Province of Manitoba that expires in 2040 and is subject to annual payments of approximately $10,000 per year. Under the mineral tenure system in Manitoba, assessment credits are "banked" to enable the claims to be held without annual payments provided sufficient exploration credits are expended on the Property. Currently, the Company has sufficient exploration credits to keep the Project in good standing for over 10 years.
該公司及其子公司共持有99份礦產索賠和一份礦產租約(Makwa),用於基本金屬勘探。Gossan Resources還有51份採礦索賠可供選擇,期權下還有30萬美元的期權付款,將於2025年4月到期。Makwa存款是根據曼尼托巴省批准的礦產租約持有的,該租約將於2040年到期,每年約需支付1萬美元。根據馬尼托巴省的礦產保有制度,評估信貸被 “存入”,以便在不支付年度付款的情況下保留索賠,前提是將足夠的勘探信貸用於財產。目前,該公司擁有足夠的勘探信用,可以使該項目在10年內保持良好的信譽。

Exploration Potential
探索潛力
The Company views the updated MM resource estimate as an important base upon which it can expand. The Company notes that by far the majority of the exploration completed to date has focused on near surface disseminated mineralization. The higher-grade cores of the deposits and higher-grade values associated with massive sulfides in multiple drill holes give clear indication that the potential for higher-grade massive sulfide is evident throughout the belt as well as proximal to the known deposits.
該公司將最新的MM資源估算視爲其擴展的重要基礎。該公司指出,到目前爲止,迄今爲止完成的大部分勘探都集中在近地表浸染礦化上。礦牀的更高品位岩心以及與多個鑽孔中的塊狀硫化物相關的更高品位值清楚地表明,在整個礦帶以及已知礦牀的附近,更高品位的塊狀硫化物的潛力顯而易見。
The Project has several walk-up targets that could provide immediate upside to the current mineral resource. These include the newly acquired New Manitoba Cu-Ni historical occurrence and the untested EM conductors between New Manitoba and the Mayville Cu-Ni Deposit approximately 10 km to the west. As well, the newly acquired Page and Ore Fault deposits and their potential extensions are also priority targets. The Company plans to complete an initial drill program to test these priority targets later this year and will provide further details on the targets and timing as soon as possible.
該項目有幾個逐步實現的目標,可以立即爲當前的礦產資源提供上行空間。其中包括新收購的新馬尼托巴省銅鎳歷史遺蹟,以及新曼尼托巴省與向西約10公里處的梅維爾銅鎳礦牀之間未經測試的電磁導體。同樣,新收購的Page和Ore Fault礦牀及其潛在延期也是優先目標。該公司計劃在今年晚些時候完成初步的鑽探計劃,以測試這些優先目標,並將儘快提供有關目標和時間的更多詳細信息。

In summary, the updated open-pit resource estimate for the Mayville deposit includes 32.0 million tonnes in the indicated category with 0.40% Cu and 0.16% Ni and byproduct concentrations of cobalt, palladium, platinum and gold (0.61% copper equivalent grade). The open pit resources at Makwa include 14.2 million tonnes in the indicated category with 0.48% Ni, 0.11% Cu, 0.02% Co, 0.37 g/t Pd and 0.10 g/t Pt (0.75% nickel equivalent grade). The Makwa deposit is subdivided into a central, higher-grade zone ('HG1') and a flanking (both hanging-wall and footwall) lower-grade ('LG1') zone. The new resource estimate includes 4.8 million tonnes of the HG1 zone grading 0.89% Ni (1.26% nickel equivalent grade).
總而言之,梅維爾礦牀的最新露天資源估計包括指定類別的3,200萬噸,銅含量爲0.40%,鎳含量爲0.16%,以及鈷、鈀、鉑和金的副產品濃度(銅當量品位0.61%)。Makwa的露天礦資源包括指定類別的1,420萬噸,其中 0.48% 的鎳、0.11% 的銅、0.02% 的鈷、0.37 g/t Pd 和 0.10 g/t Pt(0.75% 的鎳當量品位)。Makwa礦牀被細分爲中央高等級區域(“HG1”)和側翼(包括懸掛牆和腳牆)低等級(“LG1”)區域。新的資源估算包括480萬噸的HG1區域,鎳品位爲0.89%(鎳當量品位爲1.26%)。
The previous resource estimate for the MM Project was published by RPA Inc. (2014) and supported a Preliminary Economic Assessment based on two open pit mines feeding a central concentrator to be located at the Mayville property. Low base metal prices during the period of 2014 to 2020 precluded any significant new development activity and drilling at the Project. However, with an improved outlook for copper prices and the increasing strategic importance of nickel as a critical metal, the Project ranks favourably for future exploration and development.
MM項目先前的資源估算由RPA Inc.(2014年)發佈,支持了一項初步經濟評估,該評估基於位於梅維爾地產的兩座露天礦山爲中央選礦廠供水。在2014年至2020年期間,基本金屬價格低迷,使該項目無法進行任何重大的新開發活動和鑽探。但是,隨着銅價前景的改善以及鎳作爲關鍵金屬的戰略重要性日益增強,該項目在未來的勘探和開發中名列前茅。
Compared to the previous published resource estimate for the MM project (RPA Inc., 2014), the combined open pit resources (indicated category) increased by 12.4 million tonnes or 36.8%. This increase is largely attributable to the inclusion of recent infill drilling (Makwa - 2022), improved metallurgical recoveries from testwork completed after the previous resource estimate was published, and a more favourable US dollar to Canadian dollar exchange rate.
與先前公佈的MM項目資源估算(RPA Inc.,2014年)相比,合併露天礦資源(指定類別)增加了1,240萬噸,增長了36.8%。這一增長主要歸因於包括最近的填充鑽探(Makwa-2022年)、在上次資源估算公佈後完成的測試工作中提高了冶金回收率,以及美元兌加元的匯率更加有利。
Mayville Deposit
梅維爾存款
The Mayville magmatic sulfide deposit is a copper-rich disseminated sulfide deposit hosted by the western part of the ~17 km long late Archean Mayville mafic-ultramafic complex. The Mayville deposit is approximately 1.5 km long, up to 200 metres wide, and has been delineated to maximum depth of ~500 metres. It dips steeply to the south. The deposit includes the Main Zone (Figure 2, below) and two satellite zones (not shown here) located at the eastern end of the deposit. The two satellite zones have not been included in the current resource estimate.
梅維爾岩漿硫化物礦牀是一個富含銅的浸染硫化物礦牀,位於長約17千米的晚阿奇安·梅維爾鎂鐵質-超鎂鐵質複合體的西部。梅維爾礦牀長約1.5公里,寬度可達200米,最大深度已劃定爲約500米。它急劇向南傾斜。該礦牀包括主區域(見下圖 2)和位於礦牀東端的兩個衛星區域(此處未顯示)。這兩個衛星區未包括在目前的資源估計中。
The mineralization in the Mayville deposit occurs principally as disseminations of chalcopyrite and pyrrhotite with lesser pentlandite and pyrite hosted in what has been described as an intrusive breccia unit emplaced near the base of the Mayville Complex.
梅維爾礦牀的礦化主要是黃銅礦和硫鐵礦的散佈,較小的五邊形巖和黃鐵礦位於梅維爾綜合體底部附近的據稱侵入性角礫岩單元中。

The Makwa deposit is a conventional, basal-contact related, Ni- and Pd-rich disseminated magmatic sulfide deposit. The steep south-dipping and west-plunging Makwa deposit has a minimum strike length of 1.1 km, an average vertical depth of ~350 metres and an average width of 30-50 metres. The Makwa deposit remains open along strike to the east and partially down-dip below its currently defined vertical extent. The deposit was briefly mined from a shallow open pit by a subsidiary of Falconbridge Ltd. in 1974. It was the subject of a standalone Prefeasibility Study completed in 2008 (Micon International) for the mining and production of nickel concentrate for sale to a smelter.
Makwa礦牀是一種傳統的、與基底接觸有關的、富含鎳和鈀的浸染型硫化物岩漿礦牀。陡峭的南傾和向西傾斜的Makwa礦牀的最小走向長度爲1.1千米,平均垂直深度約爲350米,平均寬度爲30-50米。Makwa礦牀在向東走向沿線保持開放,部分向下傾斜至目前確定的垂直範圍以下。1974年,Falconbridge有限公司的一家子公司從一個淺層露天礦中短暫地開採了該礦牀。這是一項獨立的預可行性研究(美康國際)的主題,該研究旨在開採和生產出售給冶煉廠的鎳精礦。
The Micon resource estimate discussed here subdivides the deposit into a central higher-grade zone (HG1) and a flanking lower-grade zone (LG1). The metal tenor in both zones is very similar, such that the Ni (and Pd) grades are strongly correlative with the total amount of sulfide present. Localized high-grade nickel mineralization is present in associated with narrow lenses of net-textured and semi-massive sulphides. A longitudinal section of the deposited is shown in Figure 4 and a sectional view of the mineralization block model is shown in Figure 3 below.
此處討論的美康資源估算將礦牀細分爲中央高品位區域(HG1)和兩側低品位區域(LG1)。這兩個區域的金屬含量非常相似,因此鎳(和鈀)等級與存在的硫化物總量密切相關。局部的高品位鎳礦化與網狀和半塊狀硫化物的窄透鏡有關。沉積物的縱向截面如圖 4 所示,礦化區塊模型的剖面圖如下圖 3 所示。

Resource Modeling Methods
資源建模方法
The mineral resource estimation (MRE) strategy adopted for the Makwa and Mayville deposits comprises the following sequence:
對馬誇和梅維爾礦牀採用的礦產資源估計(MRE)策略包括以下順序:
- Exploratory data analysis/review
- Modelling
- Compositing/Grade Capping/Statistics
- Geostatistics/Variography/Spatial Analysis
- Definition of Block Model and Search Parameters
- Grade Interpolation and Validation
- Determination of Tonnage
- Establishment of Parameters/Prospects for Economic Recovery
- Mineral Resource Definition: parameters; classification
- 探索性數據分析/審查
- 建模
- 作文/成績上限/統計
- 地統計學/變異學/空間分析
- 區塊模型和搜索參數的定義
- 成績插值和驗證
- 噸位的測定
- 確定經濟復甦的參數/前景
- 礦產資源定義:參數;分類
While both the Makwa and Mayville deposits belong to the same deposit class, the former is nickel dominant while the later is copper dominant. Accordingly, the two deposits have been estimated separately.
雖然Makwa和Mayville礦牀屬於同一個礦牀類別,但前者以鎳爲主,後者以銅爲主。因此,這兩筆存款是分開估算的。
The bulk of the new resources estimated are constrained by optimized pit shells. In addition, a small underground resource was also estimated by Micon for both Makwa and Mayville.
估計的大部分新資源都受到優化的礦坑外殼的限制。此外,Micon還估計了Makwa和Mayville的少量地下資源。
