Narrow-vein modelling and Mineral Resource estimation ...

Narrow veins are major sources of many commodities, including gold, silver, tin, tungsten, coal, uranium and sometimes copper, lead and zinc. Mining this narrow style of mineralization can be considered as relatively high risk, not only due to the high cost of exploration and mining per unit of metal, but also to the frequently limited size of the resource.

The Narrow Vein Mining Advantage Great Eastern Gold

Secondly, narrow vein mining is far more precise in targeting the ore body. In most mining operations, the size of the excavations needed to allow access for their large machinery is much larger, which dilutes the grade of gold they take can take, meaning for every ounce of gold produced, significantly more rock needs to excavated.

Choice of Method - Welcome to the Narrow-Vein Mining Project

Conventional cut-and-fill, shrinkage and panel mining are typically employed by Kinross to excavate the narrower gold bearing vein structures. Each of the preceding mining methods are used to extract vein structures in vertical and or near horizontal attitudes. Veins mined by these methods typically range from 0.20 m to 2 m (0.65 to 6.5 ft) and ...
