Abstract
A gold detection apparatus capable of detecting gold in field mineral samples such as rock or soil with little or no preparation. Light in red and violet wavelengths is directed at a surface of a mineral sample and the reflected light intensity is measured by an array of sensors or pixels. Based on the characteristic reflectance properties of gold, the reflected light intensity in each wavelength is used to determine the presence of gold particles.
