Narrow vein systems represent an important source of gold which have generally been exploited by small to medium sized companies Their evaluation poses particular problems because of their grade and geological complexities The determination of grade is arguably the most important activity in resource estimation as it is generally grade and not tonnage that makes
One of the most important considerations in narrow vein mining is to minimize diluting the ore with waste rock from outside of the vein That involves careful determination of the blast hole pattern so that the ore breaks but the waste rock remains in place Stopes need to have a minimum width to allow the miners room to work within the stopes
