Blake Hylands, P.Geo., CEO of Lithium Ionic, commented, "The initial mineral resource at Salinas marks a significant milestone for us, establishing the Project as another cornerstone asset for the Company. When we acquired the Salinas properties 12 months ago, we recognized the capacity for these claims to quickly and significantly scale our resource base, and it's very exciting for us to see this materialize. Our exploration team is confident that the initial discoveries at Salinas are just the beginning, and the next phase of drilling is underway to reveal the full scope of the potential. While our focus remains on near-term production at Bandeira, we now have another meaningful deposit to advance in parallel."

Lithium Ionic首席執行官布萊克·海蘭茲P.Geo評論說:“薩利納斯的初始礦產資源對我們來說是一個重要的里程碑,使該項目成爲公司的另一項基石資產。當我們在12個月前收購薩利納斯的房產時,我們意識到這些索賠有能力快速顯著擴大我們的資源基礎,看到這一點我們感到非常興奮。我們的勘探團隊相信,薩利納斯的初步發現僅僅是開始,下一階段的鑽探正在進行中,以揭示全部潛力。雖然我們的重點仍然是Bandeira的短期產量,但我們現在還有另一筆有意義的存款可以同時推進。”

Carlos Costa, P.Geo., Lithium Ionic's VP of Exploration, commented, "This maiden NI 43-101 mineral resource estimate at a third project site is a major achievement for Lithium Ionic and I am very proud of what our exploration team has accomplished in only eight months. Our efforts will continue over the next year, with a focus on significantly expanding upon the excellent foundation established at both Salinas and Bandeira. We are one of the only lithium companies in the region with large lithium deposits being delineated at multiple sites. Within our large land package in the Lithium Valley, it is our belief that we will continue to identify additional deposits over time and continue to grow our resources to a globally important scale."

Lithium Ionic勘探副總裁Carlos Costa,P.Geo. 評論說:“對第三個項目地點的首次NI 43-101礦產資源估算是鋰離子公司的一項重大成就,我爲我們的勘探團隊在短短八個月內取得的成就感到非常自豪。我們將在明年繼續努力,重點是大幅擴大在薩利納斯和班德拉建立的良好基礎。我們是該地區僅有的在多個地點劃定大型鋰礦牀的鋰公司之一。在我們位於鋰谷的大型土地一攬子計劃中,我們相信,隨着時間的推移,我們將繼續發現更多的礦牀,並繼續將我們的資源增長到全球重要的規模。”

Salinas Lithium Project – Initial Mineral Resource Estimate

薩利納斯鋰項目——初步礦產資源估算

Strong Foundation with Outstanding Scale Potential

堅實的基礎,卓越的規模潛力

The Salinas Project is located in the lithium-rich Araçuaí Pegmatite District, in the northern part of the Eastern Brazilian Pegmatite Province, which hosts the largest lithium reserves in Brazil.

薩利納斯項目位於巴西東部偉晶岩省北部的富含鋰的阿拉蘇艾偉晶岩區,該地區擁有巴西最大的鋰儲量。

Salinas is situated approximately 100 kilometres north of the Bandeira Project where feasibility studies are being finalized, and approximately 20 kilometres east of the Salinas municipality, a town of approximately 40,000 people.

薩利納斯位於班德拉項目以北約100公里處,該項目正在完成可行性研究,位於薩利納斯市以東約20公里處,該鎮人口約爲4萬人。

The Salinas MRE contain M&I resources of 5.86Mt grading 1.09% Li2O, containing 158,678 tonnes of Lithium Carbonate Equivalent ("LCE"), the benchmark equivalent raw material used in the lithium industry, along with Inferred resources of 8.90Mt grading 0.97% Li2O in the Inferred category, or 214,572 tonnes of LCE (see MRE results in Table 1). The MRE is based on 122 diamond drill holes comprising 27,030 metres of drilling completed between May 2023 and November 2023. An additional 24 holes (6,001 metres) have been drilled since then.  

SalinasMRE包含586萬噸的M&I資源,Li2O等級爲1.09%,含有158,678噸碳酸鋰當量(“LCE”),這是鋰行業使用的基準當量原材料,以及推斷類別中890萬噸Li2O的推斷資源,即214,572噸LCE(見表1中的MRE結果)。MRE 以 2023 年 5 月至 2023 年 11 月期間完成的 122 個金剛石鑽孔爲基礎,包括 27,030 米的鑽探。從那時起,又鑽了24個洞(6,001米)。

GE21 collaborated closely with the Company's geological team to confirm the presence of a series of North-East trending moderately SE dipping pegmatite veins extending up to 1,200 meters along strike, from surface to a depth of approximately 300 meters .

GE21與該公司的地質小組密切合作,證實了一系列向東北傾斜的中度傾斜偉晶岩礦脈,沿走向延伸至1,200米,從地表延伸到大約300米的深度。

In addition to the MRE, GE21 analyzed results from drill holes located outside of the mineral resource area in the newly discovered Noé target, which is believed to be the northeast extension of a large outcropping pegmatite that has been mined for spodumene intermittently for several decades called "Lavra do Zoe". This pegmatite body is at least 15 metres thick and has a strike length of at least 210 metres.

除了 MRE 之外,GE21 還分析了位於新發現的 Noeé 目標礦產資源區之外的鑽孔結果,據信該目標是一塊名爲 “Lavra do Zoe” 的大型露頭偉晶岩的東北延伸,幾十年來一直間歇性地開採鋰輝石。這種偉晶岩體厚度至少爲 15 米,走向長度至少爲 210 米。

Based on the initial drilling to date, GE21 has identified the Noé target as having strong near-term potential to further increase the MRE by between 10-15Mt with grades ranging from 1.0-1.3% Li2O following the completion of additional drilling*.

根據迄今爲止的初步鑽探,GE21已確定Noe的目標在短期內具有很強的潛力,在完成額外鑽探後,將MRE進一步增加10-15Mt,品位介於1.0-1.3%Li2O之間*。

Exploration work and drilling will be ongoing at Salinas for the remainder of 2024 to continue to expand and upgrade the mineral resources. An upgraded MRE for Salinas is expected later this year.

在2024年的剩餘時間裏,薩利納斯的勘探工作和鑽探工作將持續進行,以繼續擴大和升級礦產資源。薩利納斯的MRE預計將於今年晚些時候升級。

The NI 43-101 technical report for the MRE, will be accessible on SEDAR+ () under the Company's issuer profile and the Company's website within 45 days of this news release.

在本新聞發佈後的45天內,將在公司發行人簡介下的SEDAR+()和公司網站上發佈MRE的NI 43-101技術報告。

*The potential quantity and grade of the lithium mineralization at the Noé target is conceptual in nature and there has been insufficient exploration to estimate a Mineral Resource or Reserve and it is uncertain if further exploration will confirm the target ranges.

*Noé目標處鋰礦化的潛在數量和品位本質上是概念性的,勘探不足以估算礦產資源或儲量,也不確定進一步的勘探能否確認目標範圍。

Details related to the calculation of the MRE

與 MRE 計算相關的詳細信息

The MRE was prepared by Leonardo Soares, P.Geo., M.Sc., of GE21 (the "Author" or "QP") with an effective date of January 4, 2024.

MRE由GE21的P.Geo.,理學碩士萊昂納多·蘇亞雷斯編寫(“作者” 或 “QP”),生效日期爲2024年1月4日。

The MRE was prepared using the following geological and resource block modeling parameters which are based on geological interpretations, geostatistical studies, and best practices in mineral estimation.

MRE 是使用以下地質和資源區塊建模參數編制的,這些參數基於地質解釋、地質統計研究和礦物估算的最佳實踐。

The QP is not aware of any factors or issues that materially affect the MRE other than normal risks faced by mining projects in the province in terms of environmental, permitting, taxation, socio-economic, marketing, and political factors, and additional risk factors regarding inferred resources.

除了該省採礦項目在環境、許可、稅收、社會經濟、營銷和政治因素以及與推斷資源有關的其他風險因素方面面臨的正常風險外,QP沒有發現任何對MRE產生重大影響的因素或問題。

  • The Project geology comprises Neoproterozoic age sedimentary rocks of Araçuaí Orogen intruded by fertile Li-bearing pegmatites originated by fractionation of magmatic fluids from the peraluminous S-type post-tectonic granitoids of Araçuaí Orogen. Lithium mineralization is related to concordant and discordant swarms of spodumene-bearing tabular pegmatites hosted by cordierite-biotite-quartz schists.

  • Drilling conducted by Lithium Ionic included diamond core drilling of NTW (64.2mm diameter).

  • Diamond core has been sampled in intervals of ~ 1 m where possible, otherwise intervals less than 1 m have been selected based on geological boundaries. Geological boundaries have not been crossed by sample intervals. 1⁄2 core samples have been collected and submitted for analysis, with regular field duplicate samples collected and submitted for QA/QC analysis.

  • Drill core samples were submitted to SGS Geosol laboratories in Brazil where they were analyzed for a 31-element suite via ICP90A (fusion by sodium peroxide and finish with ICP- MS/ICP-OES). Assay data were composited to 1 m.

  • The MRE was estimated from the diamond drill holes completed by Lithium Ionic from May 2023 until November 2023. Data from a total of 122 drill holes comprising 3,276 assays were included in the mineral resources model.

  • The 3D modelling of lithium Mineral Resources was conducted using a minimum cut-off grade of 0.3% Li2O within a preliminary lithological model.

  • The interpolation was conducted using Krigging methodology with three interpolation passes.

  • The block model was defined by a block size of 5 m long by 5 m wide by 5 m thick and covers a strike length of approximately 1,200 m to a maximal vertical depth of 300 m below surface.

  • The MRE was classified as Measured, Indicated and Inferred Mineral Resource based on data quality, sample spacing, and pegmatite continuity. The Measured Mineral Resource was defined using a search ellipsoid of 50 m by 50 m by 30 m, and where the continuity and predictability of the mineralized units was reasonable. The Indicated Mineral Resource was defined using a search ellipsoid 100 m by 100 m by 50 m. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 100 m by 100 m by 50 m for all remaining blocks.

  • Classification focused on spatial relation using a minimum of five composites in at least three different drill holes for the Measured and Indicated resources.

  • Validation has proven that the block model fairly reflects the underlying data inputs. Variability over distance is relatively moderate to low for this deposit type therefore the maximum classification level is Indicated.

  • Mineralization at the deposits extends to surface and is expected to be suitable for open cut mining; no minimum mining width was applied; internal mining dilution is limited to internal barren pegmatite and/or host rock intervals within the mineralized pegmatite intervals; based on these assumptions, it is considered that there are no mining factors which are likely to affect the assumption that the deposit has reasonable prospects for eventual economic extraction.

  • It is the QP's opinion that the current classification used is adequate and reliable for this type of mineralization and MRE.

  • Initial Metallurgical tests results are not available at this stage of project advancement. An assumed concentrate (DMS) recovery of 65% has been applied in determining reasonable prospects of eventual economic extraction.

  • Mineral Resources were constrained within the boundaries of an optimized pit shell using the following constraints: Concentrate price: USD$2,750; mining costs: USD$2.5/t ROM; Processing costs: USD$12.5/t ROM, General/Admin: USD$4.0/t ROM, Lithium Recovery: 65%, Mining Recovery: 95% and Pit slope: 60°.

  • The MRE reported is a global estimate with reasonable prospects of eventual economic extraction.

  • 該項目的地質包括阿拉誇伊造山脈的新元古代時代沉積岩,這些沉積岩被肥沃的含鋰偉晶岩侵入,這些偉晶岩來自阿拉誇伊造山脈的過鋁S型構造後花崗岩的岩漿流體的分離。鋰礦化與一致和不協調的含鋰輝石板狀偉晶岩群有關,這些偉晶岩由堇青石-黑雲石-石英片岩構成。

  • Lithium Ionic進行的鑽探包括對NTW(直徑爲64.2mm)的金剛石岩心鑽探。

  • 儘可能以約 1 m 的間隔對鑽石巖芯進行採樣,否則將根據地質邊界選擇小於 1 m 的間隔。樣本間隔沒有跨越地質邊界。已經收集了 1⁄2 個岩心樣本並提交分析,定期收集現場重複樣本並提交質量保證/質量控制分析。

  • 鑽芯樣本被提交給巴西的 SGS Geosol 實驗室,在那裏通過 ICP90A(過氧化鈉融合,最後使用 ICP-MS/ICP-OES)對這些樣本進行分析,以獲得 31 種元素的組合。分析數據合成到 1 m。

  • MRE 是根據 Lithium Ionic 在 2023 年 5 月至 2023 年 11 月期間完成的金剛石鑽孔估算得出的。礦產資源模型中包含了來自總共122個鑽孔的數據,包括3,276次化驗。

  • 鋰礦物資源的三維建模是在初步巖性模型中使用0.3%的Li2O的最低臨界品位進行的。

  • 插值是使用 Krigging 方法進行的,有三次插值通道。

  • 區塊模型定義的區塊大小爲長 5 米、寬 5 米、厚 5 米,其走向長度約爲 1,200 米,最大垂直深度爲地表以下 300 米。

  • 根據數據質量、樣本間距和偉晶岩連續性,MRE 被歸類爲測量、指示和推斷的礦產資源。測得的礦產資源是使用50 m x 50 m x 30 m的搜索橢球來定義的,並且礦化單位的連續性和可預測性是合理的。指定礦產資源是使用搜索橢球 100 m x 100 m x 50 m 來定義的。推斷礦產資源被分配給所有剩餘區塊的鑽孔間距大於 100 m x 100 m x 50 m 的區域。

  • 分類側重於空間關係,在測量和指示資源的至少三個不同的鑽孔中使用至少五種複合材料。

  • 驗證已經證明,分組模型公平地反映了基礎數據輸入。對於這種礦牀類型,距離上的變異性相對中等至低,因此顯示了最大分類級別。

  • 礦牀的礦化作用延伸到地表,預計適合露天開採;沒有適用最低開採寬度;內部採礦稀釋僅限於礦化偉晶岩區間內的內部貧乏偉晶岩和/或主巖間隔;基於這些假設,認爲沒有任何採礦因素可能影響該礦牀最終具有合理經濟開採前景的假設。

  • QP認爲,目前使用的分類對於這種類型的礦化作用和地雷風險評估是足夠和可靠的。

  • 在項目推進的現階段,尚無初步冶金測試結果。假設的濃縮物(DMS)回收率爲65%,已用於確定最終經濟開採的合理前景。

  • 使用以下約束條件將礦產資源限制在經過優化的礦殼範圍內:精礦價格:2750美元;採礦成本:2.5美元/噸ROM;加工成本:12.5美元/噸ROM,一般/管理:4.0美元/噸ROM,鋰回收率:65%,採礦回收率:95%,礦坑斜率:60°。

  • 報告的MRE是一項全球估計,具有合理的最終經濟開採前景。

Bandeira Feasibility Study Update

Bandeira 可行性研究最新情況

A Feasibility Study for Bandeira is currently being finalized by AtkinsRéalis (formerly SNC-Lavalin). Results were recently presented to the Company, which were in line with guidance and expectations, however certain aspects of the study require additional work to meet the standard of accuracy expected at a feasibility level study. Further detail is being developed on installed equipment costs to ensure the capital estimate meets a level of precision suitable for project financing. While the CAPEX of the Project is not expected to be materially different from the PEA results, this additional work will increase the certainty of the economic model and better support the transition to the execution phase of the project. AtkinsRéalis has indicated that they require approximately 4-6 weeks from today's date to complete this additional work. The Company is capitalizing on this additional time to complete further metallurgical process tests to optimize dense media recoveries. Losses associated with fines during the crushing stage are typical in DMS (Dense Media Separation) circuits, however the Company is exploring solutions to maximize the recoveries of these fines to further enhance the project. The completion of the Feasibility Study is now expected in May 2024.

阿特金斯雷阿利斯(前身爲SNC-Lavalin)目前正在完成班德拉的可行性研究。最近向公司提交了結果,這些結果符合指導和預期,但是該研究的某些方面需要額外的工作才能達到可行性研究中預期的準確性標準。正在制定有關安裝設備成本的更多細節,以確保資本估算達到適合項目融資的精確水平。儘管預計該項目的資本支出與PEA的結果不會有重大差異,但這項額外工作將增加經濟模型的確定性,更好地支持項目向執行階段的過渡。阿特金斯雷阿利斯表示,從今天起,他們需要大約4-6周的時間才能完成這項額外工作。該公司正在利用這段額外的時間來完成進一步的冶金工藝測試,以優化密集介質回收率。粉碎階段與細粉相關的損失在DMS(密集介質分離)迴路中很常見,但是該公司正在探索解決方案,以最大限度地回收這些粉末,以進一步加強該項目。可行性研究現在預計將於2024年5月完成。

Helio Diniz, President of Lithium Ionic, commented, "The Feasibility Study is nearing completion, with results aligning closely with our expectations and projections. Our current focus is on ensuring that the quality and level of detail of the study meets our expected standard, while also exploring every avenue for project optimization before advancing to the next stages of development. We are confident that this diligent work will result in a highly accurate and reliable study that will support a seamless transition to the execution phase of the project."

Lithium Ionic總裁Helio Diniz評論說:“可行性研究即將完成,結果與我們的預期和預測非常一致。我們目前的重點是確保研究的質量和細節水平符合我們的預期標準,同時在進入下一個開發階段之前探索項目優化的所有途徑。我們相信,這項辛勤工作將產生一項高度準確和可靠的研究,這將支持項目無縫過渡到執行階段。”

Bandeira Environmental Licence On-Track

Bandeira 環境許可證步入正軌

The review of the Concomitant Environmental and Installation License ("LAC", or Licença Ambiental Concomitante in Portuguese) application for the Bandeira Project is well underway by the Minas Gerais State Department of Environment and Sustainable Development ("SEMAD"). Since submitting the application in November 2023 (see press release dated November 21, 2023), Lithium Ionic has engaged in productive discussions with SEMAD, during which no significant concerns or issues were highlighted. The license is expected to be granted in early Q3 2024, aligning with our projected timeline.

米納斯吉拉斯州環境與可持續發展部(“SEMAD”)正在對班德拉項目的伴隨環境和安裝許可證(葡萄牙語中的 “LAC”,或Licenca Ambiental Concomitante)申請的審查工作正在順利進行。自2023年11月提交申請(見2023年11月21日的新聞稿)以來,Lithium Ionic一直與SEMAD進行了富有成效的討論,在此期間沒有強調任何重大擔憂或問題。該許可證預計將在2024年第三季度初發放,與我們的預計時間表一致。
