Rock with native gold provided by Weinrich Minerals. The streak test is a way to identify minerals, including gold, by rubbing them on an unglazed ceramic tile and observing the color of the streak they leave. Gold will leave a gold streak, while other minerals like pyrite and mica leave black and white streaks, respectively.
microcline), acid plagioclase (oligoclase), mica (biotite, muscovite), and amphibole. The gabbro contains mafic plagioclase (calcium enriched feldspar with high anorthite component), pyroxene, amphibole, mica, magnetite, and olivine. The gold is particulate within arsenopyrite grains. The RGO ore is a complex refractory gold ore.
