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.

TerraX的耶洛奈夫城市黄金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，黄金分析是耗时且昂贵的。因此，可以在现场或在比金更广泛的尺度上使用的不同金矿化类型的指标将有助于在该带中进行更有效的勘探。本项目的目标是：1）使用TerraX的可用分析数据集来确定不同矿化类型的潜在主/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纸浆、粗弃物和岩心/露头，以便通过pXRF分析评估分析数据的再现性; 3）通过已知的矿化，未矿化，便携式XRF是一种手持式技术，可提供该地区的即时地球化学数据，领域因此，如果通过pXRF可测量的与矿化类型系统相关的主元素和微量元素被确定，则勘探的时间和金钱费用可以显著减少。黄金资源是北方地区经济的重要贡献者，耶洛奈夫带是加拿大几个世界级太古代金矿带之一。该项目将有一个早期的数据评估阶段，定期报告和TerraX地质学家、PI和项目学生之间的会议。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让。
