Geochemical indicators of mineralization at the Yellowknife gold belt

TerraX的Yellowknife City Gold项目包括加拿大主要黄金区之一的700多平方公里的连续土地。通过广泛的钻探和分析，TerraX增加了该地区的已知资源，并发现了新的矿体。然而，黄金分析既耗时又昂贵。因此，可以就地或在比金矿更大的范围内使用的不同金矿化类型的指示将有助于在该带进行更有效的勘探。该项目的目标是：1)使用来自TerraX的可用分析数据集来确定不同矿化风格的潜在主/次元素向量；2)通过便携式x射线荧光（pXRF）重新评估与这些分析相对应的牙髓、粗弃料和岩心/露头，以评估pXRF分析分析数据的可重复性；3)通过该区已知的矿化、未矿化以及目前的目标构造运行测绘和pXRF样带，以评估pXRF作为该地区矢量工具的能力。便携式XRF是一种手持式技术，可在现场提供即时的地球化学数据。因此，如果能够识别出与成矿类型有系统关联的pXRF可测量的主量元素和微量元素，则可以显著减少勘探的时间和金钱费用。黄金资源是北部地区经济的重要贡献者，黄刀带是加拿大几个世界级的太古宙金带之一。该项目将在早期阶段进行数据评估，定期报告，并在TerraX地质学家、项目负责人和项目学生之间举行会议。在后期阶段，与公司地质学家进行为期六周的直接工作，将进一步确保知识的转移。

The Yellowknife City Gold project from TerraX includes over 700 square kilometers of contiguous land in one of the major gold districts in Canada. Through extensive drilling and assaying, TerraX has increased the known resources in the region and discovered new ore bodies. However, gold assaying is time consuming and expensive. Therefore indicators for the different gold mineralization styles that can be used in-situ or at broader scales than gold would be useful towards more efficient exploration in the belt.The objectives of this project are: 1) to use the available assay dataset from TerraX to determine potential major/minor element vectors towards different mineralization styles; 2) to re-evaluate pulp, coarse rejects, and core/outcrop corresponding to those assays through portable X-ray fluorescence (pXRF) in order to assess the reproducibility of assay data by pXRF analyses; 3) to run mapping and pXRF transects through known mineralized, unmineralized, as well as currently targeted structures in the belt to evaluate the capabilities of pXRF as a vectoring tool in the district.Portable XRF is a hand held technique that provides immediate geochemical data in the field. Therefore, if major and trace elements measurable through pXRF that correlate systematically with mineralization styles are identified, the time and monetary expense of exploration could be significantly reduced. Gold resources are a significant contributor to the economy of northern regions and the Yellowknife belt is one of several world-class Archean gold belts in Canada.This project will have an early stage of data evaluation with periodic reports and meetings between TerraX geologists, the PI and the student in the project. A later stage with six weeks of direct work with the company geologists will further ensure transfer of knowledge.
