The course of the veins is certainly not uniform; they run in varied directions, and are often tortuous as well as displaced by faults.

More generally gold occurs related to different minerals, chiefly (in decomposed ores) the oxides of iron, and (in stable ores) iron and copper pyrites, galena, blende, mispickel (all of which could also be auriferous), bismuth, stibnite, magnetite, hematite, numerous spars, and quartz.
