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.

黄金嗅探器是一种可见光光学设备，可以在钻芯、碎石、纸浆、沙子和类似材料等各种样品上进行一次90秒的测量，即可检测到黄金和其他矿物。该设备探测微米级的金、黄金合金、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像素数码照片来确定金属和矿物的浓度、颗粒大小和形状以及矿物组合，并使用检测小至1.6微米的颗粒的专用算法进行分析。该项目将研究Gold Sniffer如何测量黄金合金和矿物的二维表面浓度，并利用这些信息提供样品的金属和矿物浓度的估计。如果能够证明黄金嗅探器可以提供金、铜、锌和钼等金属浓度的有用估计，该公司将能够向客户展示黄金嗅探器的能力，从而向采矿和矿产勘探行业出售他们的产品和服务。黄金嗅探器测量可用于为勘探地质学家提供现场数据，以提高勘探方案的效率，为采掘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，并为冶金学家提供关于之前的成分的数据，以促进优化以提高选矿金属回收率。
