In many gold mines exploited during the gold rushes of the 19th century, vein material alone was typically sought as ore material. In most of today's mines, ore material is primarily composed of the veins and some component of the wall rocks which surrounds the veins.. The difference between 19th-century and 21st-century mining techniques and the type of ore sought is based on the grade of
