    The quartz veins in the mineralized zone are not large and have not been mined as veins underground, as they are just too small Most have a strike length of perhaps 15 to 30 feet In some districts, fine gold is all there is and as a result, there are basically no placers formed

    In other areas such as Dunolly these indicators are very thin metosomatic quartz veins, heavily mineralised with ironstone and other minerals These indicators do not hold gold themselves, but where these indicator veins intersect quartz reefs they usually form deposits of gold (nuggets) They are usually dead straight where they cross the ground

    The gold of these veins, like that of the adjacent placers, appears to be coarser than that of the Vulture vein" The tendency for coarse gold to form in smaller veins is not a hard and fast rule and there are some large veins which have produced very coarse gold (like the 16 to 1 mine in the Allegheny District of California) However, big gold
