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，可以检测黄金和其他矿物，对各种样品进行90秒的测量，如岩心，碎石，纸浆，沙子和类似材料。该设备可检测微米级的黄金、金合金、黄铁矿、黄铜矿和其他矿物。它通过拍摄一组3 mm 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组合，并使用专有算法进行分析，该算法可检测小至1.6微米的颗粒。该项目将研究Gold Sniffer如何测量金合金和矿物的二维表面浓度，并使用该信息来提供样品的金属和矿物浓度的估计。如果能够证明Gold Sniffer可以提供有用的金属浓度估计，如金，铜，锌和钼，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其产品和服务。Gold Sniffer测量可用于为勘探地质学家提供现场数据，这将提高勘探计划的效率，为采矿工作面的地质学家和采矿工程师提供数据，这将提高采矿效率，并为地质学家提供有关矿物成分的数据，这将有助于优化，以提高矿物加工中的金属回收率。

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.
