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.
