Characterization of the precious metal-bearing base metal mineralization at the Homer Lake prospect, Yellowknife greenstone belt, Northwest Territories

拟议的研究将集中在荷马湖矿区的贵金属贱金属矿化，该矿区位于西北地区耶洛奈夫市以北约25公里处。远景显示新太古代玄武岩岩性中有(半)块状硫化物聚集。由于它既具有火山成因块状硫化物矿床的特征，又具有剪切型矿床的特征，因此其成因尚不明确。拟议的研究将涉及三名高素质的人员(1名硕士，2名学士)，其中硕士将使用野外工作和微观分析方法相结合的方法，以填补对荷马湖前景、黄刀绿岩带(YGB)、南部奴隶克拉通(YGB)的研究不足。MSC将重点研究(半)块状硫化物的空间分布、组合、结构和矿物化学，并约束矿床的成因，重点是热液条件、硫的来源(S)和相对金矿侵位的时间。这将提供一个矿床模型，解释锌铅金银在双峰镁铁质寄主组合中的富集性，并完善成矿样式。这两名理科学生将通过限制：(1)矿床形成的温度(BSC#1)和(2)使用全岩地球化学的蚀变程度(BSC#2)来补充MSC的工作。这项拟议的研究是学术界(马尼托巴大学)、政府(西北地区地质调查局)和工业界(Gold Terra Resources Corp.)之间的合作。不仅将培训学术界、政府和业界高度追捧的各种技能方面的高素质人才，包括岩心测井、数据管理和批判性思维；结果还将有助于了解YGB的矿化史。此外，这项研究的结果将有助于正在进行的和未来在YGB和奴隶克拉通进行的贱金属矿化勘探，并有助于正在进行的关于变质和变形对金属男高音的作用的辩论。这项研究的结果将有可能对包括当地土著社区在内的新界地区的经济增长产生积极影响。

The proposed research will focus on the precious metal-bearing base metal mineralization at the Homer Lake prospect, located circa 25km north of the city of Yellowknife, Northwest Territories (NT). The prospect shows (semi-)massive sulfide accumulations in Neo-Archean basaltic lithologies. The genesis of the prospect is ambiguous since it has characteristics of both volcanogenic massive sulfide and shear-hosted mineral deposits. The proposed research will involve three highly qualified personnel (1MSc, 2BSc) of which the MSc will use a combined approach of field work and micro-analytical methods to fill in the lack of research on the Homer Lake prospect, Yellowknife greenstone belt (YGB), southern Slave craton. The MSc will focus on the spatial distribution of the (semi-)massive sulfides, their assemblage, texture, and mineral chemistry and constrain the genesis of the deposit with focus on hydrothermal fluid conditions, source(s) of sulfur, and relative timing of gold emplacement. This will provide a deposit model that explains the zinc-lead?gold-silver enrichment within a bimodal-mafic host assemblage and refine the mineralization style. The two BSc students will complement the MSc's work by constraining: (1) the temperature at which the deposit formed (BSc#1) and (2) the degree of alteration using whole rock geochemistry (BSc#2). The proposed research is a collaboration between academia (University of Manitoba), government (Northwest Territories Geological Survey), and industry (Gold Terra Resource Corp.) and will not only train highly qualified personnel in various skills that are highly sought after in academia, government and industry including core logging, data management and critical thinking; the results will also aid in understanding the mineralization history of the YGB. Furthermore, results from this study will aid in on-going and future exploration of base metal mineralization in both the YGB and the Slave craton and contribute to the on-going debate on the role of metamorphism and deformation on metal tenor. The study's outcomes will have the potential to positively impact the economic growth of the NT including local Indigenous communities.
