Geochemical indicators of mineralization at the Yellowknife gold belt

来自TerraX的耶洛奈夫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。通过广泛的钻探和化验，TerraX增加了该地区的已知资源，并发现了新的矿体。然而，黄金化验既耗时又昂贵。本项目的目标是：1)利用TerraX现有的分析数据集，确定不同矿化类型的潜在主次元素向量；2)通过便携式X射线荧光分析(PXRF)重新评估与这些分析相对应的矿浆、粗碎屑和岩心/露头，以评估pXRF分析的分析数据的重复性；3)通过已知的矿化、未矿化以及当前靶区的构造进行制图和pXRF横断面，以评估pXRF作为该地区的矢量化工具的能力。便携式XRF是一种手持式技术，可提供现场即时的地球化学数据。因此，如果能识别出与成矿类型有系统关联的、可通过x射线荧光光谱测量的常量元素和微量元素，就可以大大减少勘探的时间和金钱费用。黄金资源是北方地区经济的重要贡献者，黄刀金矿带是加拿大几个世界级太古代金矿带之一。该项目将通过定期报告和TerraX地质学家、PI和项目学生之间的会议进行数据评估的早期阶段。稍后阶段将与该公司进行为期六周的直接工作，地质学家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.
