Although little detailed information is available on ore and gangue mineralogy, wallrock alteration effects, grades, production, or reserves for these deposits, they appear to be mostly typical low-sulfide gold-quartz veins, with quartz as the major gangue mineral Gold sometimes occurs as a lode deposit in small amounts in rock, known as gold ore. Gold can also be found in alluvial deposits known as placer deposits, as flakes, grains, or nuggets. Ore, a naturally occurring rock or sediment with enough minerals, must be considered economically important enough to extricate. Ores can be either metals or gems

Geology: Identify A Gold Bearing Are

There are some gold bearing areas where gold and quartz are commonly found together. Many times the gold nuggets that are found will have a very coarse texture and still have quartz attached to them down in the grooves of the nugget. This indicates that they were eroded directly from the quartz These veins are where hard rock gold mines follow and remove the gold bearing quartz. Usually, the ground where gold lodes are now used to be near volcanoes that perished many millions of years ago. To get an idea of the time span involved, some major gold-bearing quartz finds which are considered younger are about 400 million years old Rock Identification Guide.

The survey will help provide an overall structural picture of the property and identify extensions of known gold-bearing structures as well as any previously unrecognized structures on the. Placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles.When heavy, stable minerals are freed from their matrix by weathering processes, they are slowly washed downslope into streams that quickly winnow the lighter matrix. Thus the heavy minerals become concentrated in stream, beach, and lag (residual) gravels and constitute workable ore. Quartz is an important mineral element and the most abundant rock-forming mineral that controls the mineralogy of a reservoir. At the surface, quartz is more stable than most other rock minerals because it is made up of interlocking silica that makes it quite resistant to mechanical weathering. Quartz abundance is an indication of mineralization in many metal deposits; therefore. Waste rock, which consists of rock and target minerals in concentrations too low for economic recovery, is removed along with the ore. Waste rock includes granular, broken rock that ranges from fine sand to large boulders, depending on the nature of the formation and mining methods employed
