Accesswire ·  03/19 06:30

Newly permitted areas hold potential for further gold and copper prospects.

新获准的区域有可能进一步拓宽黄金和铜的前景。

LONDON, UK / ACCESSWIRE / March 19, 2024 / Meridian Mining UK. S (TSX:MNO)(Frankfurt/Tradegate:2MM)(OTCQX:MRRDF) ("Meridian" or the "Company") is pleased to announce the initial findings from positive metallurgical trials using a more selective reagent for copper sulphides. Preliminary results using Solvent 3418A achieved higher recoveries of copper ("Cu") than the ~92.4% achieved by the reagent PAX used in the 2023 PEA. Solvent 3418A is a common Cu reagent, engineered to also be an efficient collector of gold ("Au") and silver ("Ag"), which may lead to possible increases in their recoveries. Work is ongoing to verify the promising initial copper recoveries observed for future economic studies.

英国伦敦/ACCESSWIRE/2024 年 3 月 19 日/英国 Meridian Mining。S(多伦多证券交易所股票代码:MNO)(法兰克福/TradeGate: 2mm)(OTCQX: MRRDF)(“子午线” 或 “公司”)欣然宣布使用更具选择性的硫化铜试剂进行阳性冶金试验的初步发现。使用溶剂3418A的初步结果使铜(“铜”)的回收率高于2023年PEA中使用的试剂PAX的约92.4%。溶剂 3418A 是一种常见的铜试剂,其设计也是金(“Au”)和银(“Ag”)的有效收集剂,这可能会提高它们的回收率。目前正在开展工作,以验证观测到的初步铜回收率,以供未来经济研究使用。

Cabaçal's Pre-Feasibility Study ("PFS") program of infill drilling ("Figure 1") is progressing well. The drill program is currently focussed on converting Inferred zones1 hosting moderate grades of gold and copper mineralization to a higher status. Drill results have included CD-418's 16.8m @ 1.2g/t AuEq2 and CD-409's 10.0m @ 1.1g/t AuEq. Cabaçal's post-PEA drill program includes some recent robust copper dominant intersections. Further drill results are pending.

Cabacal的填充钻探预可行性研究(“PFS”)计划(“图1”)进展顺利。钻探计划目前的重点是转换推断区域1 拥有中等品位的金和铜矿化,地位更高。钻探结果包括 CD-418 的 16.8 米 @ 1.2g/t auEQ2 还有 CD-409 的 10.0m @ 1.1g/t auEQ。Cabacal的Pea后钻探计划包括一些最近以铜为主的坚固十字路口。进一步的钻探结果尚待确定。

With the simultaneous advancement of Cabaçal's PFS and Santa Helena's resource programs, the Company has focused on updating environmental permits and access agreements to unlock additional areas for further exploration upside. Multiple prospects hosting extensive copper and gold geochemical anomalies are being progressively opened to exploration.

随着Cabacal的PFS和Santa Helena资源计划的同步推进,该公司专注于更新环境许可和准入协议,以解锁更多区域,为进一步的勘探上升空间。存在大量铜和金地球化学异常的多个前景正逐步开放供勘探。

Mr. Gilbert Clark, CEO, comments: "It is great to see our metallurgical optimization trials indicating the potential for even higher recoveries of Cu than we initially achieved with the PEA. If the Au and Ag results replicate our expectations, this can only improve the already high quality of Cabaçal's Cu, Au & Ag concentrates. In addition, Cabaçal's drill program will increase confidence in the deposit's resource base, with continued Cu-Au-Ag intercepts over the 2km length of the PEA's open pit. This will be the solid base for the PFS study where we hope to confirm Cabaçal as a long-life stand-alone mine development. We are opening up more areas for exploration, expanding our field programs to test for Au and Cu mineralization along the mine corridor and its extensions. Meridian's strategy and timing to advance this emerging Cu-Au VMS belt presents a strong investment opportunity for investors seeking exposure to a development-focussed copper gold company in Brazil".

首席执行官吉尔伯特·克拉克先生评论说: “很高兴看到我们的冶金优化试验表明,铜的回收率有可能比我们最初使用PEA实现的还要高。如果金和银的结果与我们的预期相似,这只会提高Cabacal的铜、金和银精矿已经很高的质量。此外,Cabacal的钻探计划将增强人们对该矿床资源基础的信心,继续在PEA露天矿的2公里长度上截获铜金银。这将是PFS研究的坚实基础,我们希望在该研究中确认Cabacal是一个寿命长的独立矿山开发项目。我们正在开放更多勘探区域,扩大我们的实地项目,以测试矿山走廊及其延伸部分沿线的金和铜矿化情况。Meridian推进这一新兴铜金矿带的战略和时机为寻求投资巴西一家以开发为重点的铜金公司的投资者提供了强大的投资机会”。

子午线正忙于在多个战线上推进Cabacal PFS。这包括重点优化铜、金和银的冶金回收率,以及让三台钻机延续资源定义,重点是将推断资源转化为更高的可信度。

Cabaçal Metallurgical Update

Cabacal 冶金最新消息

The historical Cabaçal mine's metallurgical data and the Company's own testwork have confirmed the highly favourable metallurgical processing characteristics of the deposit's Cu-Au & Ag sulphide and free gold mineralization. Cabaçal's mineralization is characterized as soft to medium in hardness, with high recoveries via a relatively coarse 200-micron grind. Recommendations from the PEA included the evaluation of alternative reagents. The Company's metallurgical consultant, Mr. Norman Lotter, has scoped a series of tests using the selective collector Solvay 3418A ("3418A") in the rougher and copper cleaner circuit. 3418A is a widely used reagent that has a known ability to enhance copper and precious metal recoveries from sulphide mineralization, like that found at the Cabaçal deposit. Initial tests were performed using the Cabaçal PEA's master composite samples and initial results indicate higher recoveries of Cu, exceeding those used in the 2023 Preliminary Economic Assessment3. Repeat testing is scheduled to generate a comprehensive data set, to determine the total metal recoveries to be used in the PFS. Amongst the test samples are intervals with stronger or dominant copper mineralization. If 3418A continues to deliver higher metal recoveries, this will have a positive effect not only on these intersections but potentially on the broader haloes of Cu-Au mineralization currently below resource cut-off grades.

Cabacal矿的历史冶金数据和公司自己的测试工作证实了该矿床硫化铜-金和银硫化物以及游离金矿化的非常有利的冶金加工特性。Cabacal 的矿化特点是硬度软到中等,通过相对粗糙的 200 微米研磨可以获得很高的回收率。PEA的建议包括评估替代试剂。该公司的冶金顾问诺曼·洛特先生使用选择性收集器索尔维3418A(“3418A”)在更粗糙的铜清洁回路中进行了一系列测试。3418A是一种广泛使用的试剂,已知它能够提高硫化物矿化中铜和贵金属的回收率,例如在CabaCal矿床中发现的回收率。初步测试是使用Cabacal PEA的主复合样品进行的,初步结果表明,铜的回收率更高,超过了《2023年初步经济评估》中使用的回收率3。计划进行重复测试以生成全面的数据集,以确定PFS中使用的总金属回收率。测试样本中有铜矿化程度较强或占主导地位的间隔。如果3418A继续提供更高的金属回收率,这不仅会对这些交叉点产生积极影响,而且有可能对目前低于资源临界等级的更广泛的铜金矿化光环产生积极影响。

Comparative testwork was also undertaken to examine Cabaçal's flow sheet with and without a gold gravity circuit. Higher total Au recoveries were confirmed with the inclusion of a gravity circuit, than without. The importance of Au recovered by a gravity circuit extends to the Cabaçal belt's free Au, hosted both within the VMS mineralization and the late-stage gold over print.

还进行了比较测试,以检查Cabacal的流程图,有无金重力回路。经证实,加入重力回路的总金回收率要高于不包含重力回路的总金回收率。通过重力回路回收金的重要性延伸到卡巴卡尔带的游离金,这种金存在于VMS矿化区和晚期的压印金中。

The Santa Helena mine's historical floatation-only flow sheet excluded a gravity circuit and Au recoveries averaged 65%. This is the Au recovery factor used in the calculation of the 2022 Santa Helena Exploration Target4. Cabaçal's PEA outlined Au recoveries averaging 89.7%, via a combination of gravity and flotation circuits, a 38% difference. Santa Helena's mill's tailings data also records a much higher gold grade than Cabaçal's historical tailings and Meridian's own 2022 data.

圣赫勒拿矿历史上的浮动流量表不包括重力回路,金的平均回收率为65%。这是计算2022年圣赫勒拿岛勘探目标时使用的金回收系数4。Cabacal的PEA概述了通过重力和浮选回路相结合的平均金回收率为89.7%,相差38%。圣海伦娜工厂的尾矿数据也记录的黄金品位比卡巴卡尔的历史尾矿和子午线自己的2022年数据高得多。

The late-stage gold overprint has been outlined at Santa Helena5 and the potential for higher total gold recoveries, like those demonstrated at Cabaçal, will be determined by the planned metallurgical test program that will include a gravity circuit. If the potential for comparative Au recoveries is achieved from Santa Helena's metallurgical testwork, then a material increase in the Au recovery factor for the future resource calculations would be used.

圣赫勒拿岛概述了后期的黄金套印5 而且,像在Cabacal所展示的那样,更高的总金回收率的可能性将由计划中的包括重力回路在内的冶金测试计划决定。如果从圣赫勒拿的冶金测试工作中可以获得可比较的金回收率,那么将使用大幅提高金回收系数来进行未来资源计算。

Cabaçal Drilling Update

Cabacal 钻探更新

The Cabaçal resource development program continues, with three rigs currently deployed in the CNWE. Results recently received included holes from the end of the 2023 program, and initial holes from the mine area and extensions of the Cabaçal deposit to the south (Figure 1). Some holes such as CD-436 are from peripheral or close-out positions corresponding to known lower grade zones of the deposit and are inline with expectations for confirming the limits of pit design.

Cabacal资源开发计划仍在继续,目前在CNWE部署了三台钻机。最近收到的结果包括2023年项目结束时的钻孔,以及矿区的初始钻孔和向南延伸的Cabacal矿床(图1)。一些钻孔,例如 CD-436,位于与矿床已知低品位区域相对应的边缘位置或收尾位置,符合确认矿坑设计极限的预期。

From the ongoing drill program and surface mapping program results, Cabaçal's open pitable mineralization in places remains open. The remaining drill program will seek to close out the mineralization so as to optimise the pit design that will be used in the PFS. Meridian's drill program at Cabaçal continues and is expected to deliver an updated drill hole data base to its independent resource and mine design consultants over Q2-Q3 of this year.

从正在进行的钻探计划和地表测绘计划的结果来看,Cabacal在某些地方的露天矿化区仍然开放。剩余的钻探计划将寻求封闭矿化,以优化将在PFS中使用的矿坑设计。Meridian 在 Cabacal 的钻探计划仍在继续,预计将在今年的 Q2-Q3 期间向其独立资源和矿山设计顾问提供更新的钻孔数据库。

Update on New Licencing Of Exploration Areas

勘探区域新许可的最新情况

The Company continues to work with local landholders and the state environment agency, SEMA, to increase the footprint of permitted land for exploration targeting. Environmental licences for exploration (Licença de Operação Provisória Mineral "LOPM") have recently been expanded. The project has historically defined gold and base metal stream anomalies and soil anomalies that cumulatively extend over kilometers in scale. Additional areas of the greenstone belt remain open for further sampling and testing.

该公司继续与当地土地所有者和国家环境署SEMA合作,以增加允许的勘探用地占地面积。勘探环境许可证(矿业许可证 “LOPM”)最近有所扩大。该项目历来定义了金和贱金属流异常以及累积规模超过千米的土壤异常。绿岩带的其他区域仍开放供进一步采样和测试。

To the south, additional access has been approved in areas to the west of Santa Helena. The Company has already initiated soil sampling where gaps in coverage exist in the BP Minerals sampling. 200 samples have been collected and have outlined a new Cu anomaly ~ 4km to the west of Santa Helena, extending over ~575m at a 150ppm threshold. Gold assay results for this soil anomaly are pending. The area and its extensions will be targeted with future surface geophysical programs.

在南部,已批准在圣赫勒拿岛以西的地区增设通道。该公司已经启动了英国石油矿业采样中存在覆盖范围空白的土壤采样。已经收集了200份样本,并概述了圣赫勒拿岛以西约4公里处的新铜异常,在150ppm的阈值下延伸约575米。该土壤异常的金化验结果尚待确定。该区域及其延伸部分将成为未来的地表地球物理计划的目标。

The Company has also now added a total of 11 properties in the Cigarra area to the LOPM north of Cabaçal. This target lies within licences 866002/2016, 866455/2016, spanning 3,746 Ha across a 7km strike length of the northern extension of the Cabaçal Belt. The Company continues discussions with landholders to formalize agreements on some of the larger properties in the area. Historical records describe a geological / geochemical environment similar to that of the chloritic outcrops of the Cabaçal deposit setting in this region, with gold and base metal anomalies present.

该公司现在还在卡巴卡尔以北的LOPM的西加拉地区共增加了11处房产。该目标位于866002/2016、866455/2016的许可证范围内,横跨卡巴卡尔地带北延伸部分的7千米打击长度为3,746公顷。该公司继续与土地所有者进行讨论,以就该地区一些较大的房产正式达成协议。历史记录描述的地质/地球化学环境与该地区Cabacal矿床的氯化物露头相似,存在金和贱金属异常。

Meridian Mining UK S is focused on:

Meridian Mining UK S 专注于:

  • The development and exploration of the advanced stage Cabaçal VMS gold‐copper project;
  • Regional scale exploration of the Cabaçal VMS belt; and
  • Exploration in the Jaurú & Araputanga Greenstone belts (the above all located in the State of Mato Grosso, Brazil).
  • 开发和勘探已进入后期阶段的Cabacal VMS金铜项目;
  • Cabacal VMS 地带的区域规模勘探;以及
  • 探索 Jauru 和 Araputanga 绿岩带(以上均位于巴西的马托格罗索州)。

Cabaçal is a gold-copper-silver rich VMS deposit with the potential to be a standalone mine within the 50km VMS belt. Cabaçal's base and precious metal-rich mineralization is hosted by volcanogenic type, massive, semi-massive, stringer, and disseminated sulphides within deformed metavolcanic-sedimentary rocks. A later-stage gold overprint event has emplaced high-grade gold mineralization.

Cabacal是一个富含金铜银的VMS矿床,有可能成为50公里VMS带内的独立矿山。卡巴卡尔的底矿和富含贵金属的矿化由变形的变质火山沉积岩中的火山成因型、块状、半块状、串状硫化物和浸染型硫化物组成。后期的金叠印事件已经形成了高品位的金矿化。

The Preliminary Economic Assessment technical report (the "PEA Technical Report") dated March 30, 2023, entitled: "Cabaçal Gold-Copper Project NI 43-101 Technical Report and Preliminary Economic Assessment, Mato Grosso, Brazil" outlines a base case after-tax NPV5 of USD 573 million and 58.4% IRR from a pre-production capital cost of USD 180 million, leading to capital repayment in 10.6 months (assuming metals price scenario of USD 1,650 per ounces of gold, USD 3.59 per pound of copper, and USD 21.35 per ounce of silver). Cabaçal has a low All-in-Sustaining-Cost of USD 671 per ounce gold equivalent for the first five years, driven by high metallurgical recovery, a low life-of-mine strip ratio of 2.1:1, and the low operating cost environment of Brazil (see press release dated March 6, 2023).

2023年3月30日的初步经济评估技术报告(“PEA技术报告”),标题为:“巴西马托格罗索州Cabacal Gold-Copper Project NI 43-101技术报告和初步经济评估” 概述了税后NPV5为5.73亿美元的基本案例和来自1.8亿美元的内部收益率为58.4%,从而在10.6个月内实现资本偿还(假设金属价格情景为1,6美元)每盎司黄金 650 美元,每磅铜 3.59 美元,每盎司白银 21.35 美元)。在冶金回收率高、矿山条带材寿命比为2. 1:1 的低水平以及巴西的低运营成本环境(见2023年3月6日的新闻稿)的推动下,CabaCal在头五年的总体维持成本较低,为每盎司黄金当量671美元。

The Cabaçal Mineral Resource estimate consists of Indicated resources of 52.9 million tonnes at 0.6g/t gold, 0.3% copper and 1.4g/t silver and Inferred resources of 10.3 million tonnes at 0.7g/t gold, 0.2% copper & 1.1g/t silver (at a 0.3 g/t gold equivalent cut-off grade), including a higher-grade near-surface zone supporting a starter pit.

CabaCal矿产资源估算包括5,290万吨的指示资源,即0.6g/t黄金,0.3%的铜和1.4g/t的银,以及推断的1,030万吨资源,即0.7g/t黄金、0.2%的铜和1.1g/t的银(按0.3g/t的黄金当量临界等级),包括支撑起始矿坑的更高品位的近地表区域。

Technical Notes

技术笔记

Samples have been analysed at SGS and ALS laboratories in Belo Horizonte and Lima. At SGS, samples are dried, crushed with 75% passing <3 mm, split to give a mass of 250-300g, pulverized with 95% passing 150#. Gold analyses are conducted by FAA505 (fire assay of a 50g charge), and base metal analysis by methods ICP40B and ICP40B_S (four acid digest with ICP-OES finish). Visible gold intervals are sampled by metallic screen fire assay method MET150-FAASCR. At ALS, samples are dried, crushed with 70% passing 85% passing 200#. Routine gold analyses have been conducted by Au‐AA24 (fire assay of a 50g charge with AAS finish). High‐grade samples (>10g/t Au) are repeated with a gravimetric finish (Au‐GRA22), and base metal analysis by methods ME-ICP61a and OG62 (four acid digest with ICP-AES finish). Visible gold intervals are sampled by metallic screen fire assay method Au‐SCR21. Samples are held in the Company's secure facilities until dispatched and delivered by staff and commercial couriers to the laboratory. Pulps and coarse rejects are retained and returned to the Company for storage. The Company submits a range of quality control samples, including blanks and gold and polymetallic standards supplied by Rocklabs, ITAK and OREAS, supplementing laboratory quality control procedures. Approximately 5% of archived samples are sent for umpire laboratory analysis, including any lots exhibiting QAQC outliers after discussion with the laboratory. In BP Minerals sampling, gold was analysed historically by fire assay and base metals by three acid digest and ICP finish at the Nomos laboratory in Rio de Janeiro. Silver was analysed by aqua regia digest with an atomic absorption finish. True width is considered to be 80-90% of intersection width. Assay figures and intervals are rounded to 1 decimal place. Gold equivalents for Cabaçal are calculated as: AuEq(g/t) = (Au(g/t) * %Recovery) + (1.492*(Cu% * %Recovery)) + (0.013*(Ag(g/t) * %Recovery)), where:

贝洛奥里藏特和利马的SGS和ALS实验室已经对样本进行了分析。在 SGS,样品经过干燥,以 75% 的比例压碎 10g/t Au),采用重量法完成(Au‐gra22),并通过Me-ICP61a和OG62方法(经过ICP-AES表面处理的四酸消解)对贱金属进行分析。可见的金间隔是通过金属屏幕火焰分析方法Au‐SCR21采样的。样本保存在公司的安全设施中,直到工作人员和商业快递员将样本发送并交付到实验室。纸浆和粗糙废弃物被保留并返回公司进行储存。该公司提交了一系列质量控制样品,包括由Rocklabs、ITAK和OREAS提供的毛坯以及金和多金属标准,以补充实验室质量控制程序。大约5%的存档样本被送去仲裁实验室分析,包括与实验室讨论后出现QAQC异常值的任何批次。在BP Minerals的采样中,历史上是通过火法分析来分析黄金,在里约热内卢的Nomos实验室通过三次酸性摘要和ICP完成分析来分析贱金属。由王水文摘分析仪对银进行了分析,表面经过了原子吸收处理。实际宽度被视为交叉点宽度的80-90%。化验数字和间隔四舍五入到小数点后 1 位。Cabacal 的黄金当量计算公式为:aueQ (g/t) = (Au (g/t) * %回收率) + (1.492* (Cu% * %回收率)) + (0.013* (Ag (g/t) * %回收率)),其中:

  • Au_recovery_ppm = 5.4368ln(Au_Grade_ppm)+88.856
  • Cu_recovery_pct = 2.0006ln(Cu_Grade_pct)+94.686
  • Ag_recovery_ppm = 13.342ln(Ag_Grade_ppm)+71.037
  • au_recovery_ppm = 5.4368ln (au_grade_ppm) +88.856
  • cu_recovery_pct = 2.0006ln (cu_grade_pct) +94.686
  • ag_recovery_ppm = 13.342ln (ag_grade_ppm) +71.037

Recoveries based on 2022 metallurgical testwork on core submitted to SGS Lakefield

回收率基于向 SGS Lakefield 提交的 2022 年岩心冶金测试结果

Gold equivalents for Santa Helena are based on metallurgical recoveries from the historical resource calculation, updated with pricing forecasts aligned with the Cabaçal PEA. AuEq (g/t) = (Au_(g/t) * 65%Recovery) + (1.492*Cu(%) * 89%Recovery) + (0.474*Zn% * 89%Recovery)) + (0.013Ag(g/t) * 61%Recovery)).

圣赫勒拿的黄金等价物基于历史资源计算中的冶金回收率,并根据与Cabacal PEA一致的定价预测进行了更新。auEq (g/t) = (Au_ (g/t) * 65% 回收率) + (1.492*Cu (%) * 89% 回收率) + (0.474*Zn% * 89% 回收率) + (0.013Ag (g/t) * 61% 回收率))。

Soils samples have been analysed at the accredited SGS laboratory in Belo Horizonte. gold analyses have been conducted by FAA505 (fire assay of a 50g charge), and base metal analysis by portable XRF calibrated with certified references. ~10% of base metal results are verified by laboratory analysis at SGS using methods ICP40B (four acid digest with ICP-OES finish). Samples are held in the Company's secure facilities until dispatched and delivered by staff and commercial couriers to the laboratory. Pulps are retained for umpire testwork, and ultimately returned to the Company for storage. The Company submits a range of quality control samples, including blanks and gold and polymetallic standards supplied by ITAK and OREAS, supplementing laboratory quality control procedures.

土壤样本已在贝洛奥里藏特的经认可的 SGS 实验室进行了分析。黄金分析由 FAA505(50g 电荷的火法分析)进行,贱金属分析由经过认证参考文献校准的便携式 XRF 进行。大约 10% 的贱金属结果经过 SGS 实验室分析的验证(ICP-OES 表面处理的四种酸性消化法)。ICP40B样本保存在公司的安全设施中,直到工作人员和商业快递员将样本发送并交付到实验室。纸浆被保留用于裁判员的测试工作,并最终返回公司进行储存。该公司提交了一系列质量控制样品,包括ITAK和OREAS提供的空白样品以及金和多金属标准,以补充实验室质量控制程序。
