Open Pit Mining
Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure Openpit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.
Grab Sample
Grab sampling takes equal amounts of ore at selected intervals from a mine dump or muck pile. This method is not usually considered a reliable one. Other mining sampling methods are bulk sampling, channel sampling, and chip sampling. The results of all these methods are combined in order to determine the grade of the ore body.

The Quartz Page: Occurrence
Rocks are sometimes cut by quartz veins at random orientations, with or without crystals. In other cases there is an obvious pattern in the orientations of the veins: for example, when a igneous rock shrinks during cooling, the cracks may develop into a regular system of fissures that might be filled with quartz from percolating hot brines.
