Placer gold is a popular target because it has concentrated over a long period of time and is fairly easy to find if you are in gold bearing country Five Indicators that Gold May be Present Rock Types for Gold are Nearby If a certain rock type is known to be productive for gold in one zone and the same rock type exists nearby this is aGet Detail
In most gold bearing veins the gold does not form into welldeveloped crystals Unlike quartz which often forms good crystals gold requires a very specific set of circumstances to grow into good crystal shapes Few gold deposits produce good crystal specimens as most gold forms naturally as irregular masses and lumpsGet Detail
