Developing Visible Light Measurement Methods to Detect Gold and Sulphide Minerals on Unpolished Drill Core and Crushed Rock

黄金嗅探器是一种可见光光学设备，可以在90秒内对各种样品（如钻芯、碎石、纸浆、沙子和类似材料）进行单次测量，以检测黄金和其他矿物。该设备可检测微米级的金、金合金、黄铁矿、黄铜矿和其他矿物。它通过拍摄一组3mm x 4.5 mm区域的20 MP数字照片来确定金属和矿物浓度，颗粒大小和形状，以及矿物关联，这些照片使用专有算法进行分析，可检测小至1.6微米的颗粒。该项目将研究黄金嗅探器如何测量金合金和矿物的二维表面浓度，并利用这些信息对样品的金属和矿物浓度进行估计。如果可以证明Gold Sniffer可以提供有用的金属（如金、铜、锌和钼）浓度估计，该公司将能够通过向客户展示Gold Sniffer的功能，向采矿和矿产勘探行业销售他们的产品和服务。Gold Sniffer的测量结果可用于为勘探地质学家提供现场数据，以提高勘探计划的效率，为开采工作面的地质学家和采矿工程师提供数据，以提高采矿效率，并为冶金学家提供有关成分的数据，以促进矿物加工中金属回收率的优化。

The Gold Sniffer is a visible light optical device that can detect gold and other minerals with a single 90 second measurement on avariety of samples such as drill core, crushed rock, pulps, sand and similar materials. The device detects micron-sized gold, goldalloys, pyrite, chalcopyrite, and other minerals. It determines metal and mineral concentrations, particle size and shape, andmineral association by taking a set of 20 MP digital pictures of a 3 mm x 4.5 mm area which is analyzed with a proprietaryalgorithm that detects particles as small as 1.6 microns.The project will investigate how the Gold Sniffer can measure the two-dimensional surface concentration of gold alloys andminerals, and use this information to provide an estimate of the metal and mineral concentrations of a sample. If it can bedemonstrated that the Gold Sniffer can provide useful estimates of the concentrations of metals such as gold, copper, zinc, andmolybdenum, the company will be able to sell their products and services to the mining and mineral exploration industries bydemonstrating to customers the capabilities of the Gold Sniffer. The Gold Sniffer measurements can be used to provideexploration geologists with data in the field that will increase the efficiency of exploration programs, to provide data to geologistsand mining engineers at the mining face that will increase the efficiency of mining, and to provide data about the composition ofore to metallurgists that will facilitate optimization to increase metal recovery from mineral processing.
